Kombuchawhaaat? If you have never heard about this beverage, do not be afraid! The pronunciation is easier than it looks and it is tastier than it sounds! Kombucha is a beverage that results from the fermentation of black or green tea leaves and cane sugar with several bacterial and yeast species – a Symbiotic Culture Of Bacteria and Yeast (SCOBY). Kombucha is one of the rising stars in the revival of specialty fermented beverages that has been taking place in the market over the last recent years.

The rise of fermented beverages, both in variety and production volume, has been defined as one of the most important trends in 2019 within the food beverage sector. To give you a more objective picture, the global fermented beverages market is expected to increase steadily until 2023, reaching 935 billion euros (in 2015 it was valued at 600 billion euros). The beverage consumers and the millennials generation in particular have a high interest on experiencing novel and unusual flavors together with different textures and the fermentation process can strongly influence those characteristics.

What makes kombucha unique

But why is Kombucha so special within the large variety of fermented beverages? Kombucha is a low-sugar tea-based fermented beverage with considerable levels of organic acids, vitamins and polyphenols, known for their health benefits. By adding fruit, herbs or flavors into this mixture you get a quite unique and refreshing beverage that is, most often, sparkling and non-/low-alcoholic. Kombucha can have a drier and/or tarter character like the traditional ciders or the “Brett” beers and the production of alcohol can also be boosted by adjusting the fermentation conditions (if alcohol is higher than 4.5% it is referred as Hard Kombucha). The explosion of flavors present in Kombucha can be quite overwhelming in the start due to its high acidity but quite addictive afterwards. The definition of Kombucha is quite broad and there is a great variety of flavors and profiles in the market at the moment, going from soft-drink like beverages with low sugar and high drinkability to more dry and acidic beverages that can be in the direction of sour beers or dry cider.

Tea and sugar are two central ingredients for the production of kombucha

One of the best parts about Kombucha is that you can produce it at home with a very limited amount of kitchen gear, no fancy equipment being needed.

There are several dedicated websites with infographics and videos that can be very helpful before you do your first Kombucha brew, where more detailed explanations about the gear required as well as recipes and how to find and get the SCOBY. In a simplistic way, the production process of kombucha requires two fermentation steps:

  • Primary fermentation:the mixture of yeast and bacterial species converts the sugar into ethanol and organic acids. At the start of the process, oxygen is present (aerobic conditions), which promotes the cell division of the yeast species and later conversion of sugar into ethanol and carbon dioxide (CO2). The type and proportion of yeast species varies from SCOBY to SCOBY but SaccharomycesBrettanomyces, Pichia and Hanseniaspora are some of the most common ones. When sugar is depleted, ethanol becomes the most abundant carbon source, which promotes the activity of the different bacterial species that will convert it into organic acids. Species belonging to the genus AcetobacterGluconobacter and Lactobacillus are the major responsible for the production of acetic acid, gluconic acid and glucuronic acid. Acetic acid, that gives vinegar aroma and taste, is normally the most abundant organic acid when the primary fermentation is finished. At the beginning of the process the SCOBY will be at the top of the flask and during the fermentation it starts to sink, forming a new SCOBY at the top. Thus, at the end of the primary fermentation you will have two SCOBYs that can be used for two new batches of Kombucha.

  • Secondary fermentation: the Kombucha from the primary fermentation is filtered to remove the major particles and then flavored by adding fruit, juices, herbs, spices and/or others. The sugar addition from the flavoring step will promote the anaerobic fermentation of yeast, resulting in the formation of carbon dioxide (CO2) which naturally carbonates the final beverage. When this step is made directly in the bottle – bottle fermentation – it can be tricky since you need to calculate how much CO2 will be produced from the sugar added during flavoring. The first time you may get an over-carbonated beverage with too much fizz.

Even though there are many reports regarding the positive impact of Kombucha on the digestive system and gut health together with its action as anticarcinogenic, antihypertensive, antidiabetic, and hepatoprotective, it is important to note that currently, Kombucha cannot be granted with any official health claims. I believe that in a near future some concrete results from clinical studies will give a more accurate information regarding the active functionalities of Kombucha.

The Kombucha presence in the European market is still limited when comparing with the United States, where this fermented beverage can be found throughout the whole country. The implementation of Kombucha in Europe requires some more consumer education since it is a beverage with a unique and acquired taste, but it is clear that more and more people are becoming aware of its existence and benefits. Next time you see some Kombucha in a shop or pub, go for it and give it a try! Soon after there is a high chance that you will be planning your first brew of Kombucha at home.

Environmental pollution caused by industry has increased in last decades. The industrial chemical processes use mainly volatile and inflammable organic solvents and require high time and energy demands. In addition, currently, the techniques used have low extraction efficiencies and poor selectivity. The focus of scientists is now the development of more sustainable and environmental friendly chemical processes for the production, extraction and purification of biomolecules and bioactive compounds.

Ionic liquids have emerged as a promising alternative solvent since they are known by their non-flammable, non-volatile and recyclable character, being many times called green solvents. Since Paul Walden described the first ionic-liquid (ethylammonium nitrate) in 1914, the ionic liquids became one of the major scientific area of research and the number of papers addressing their outstanding properties has exponentially increased from a few to more than 5000 in the last 20 years.

In this piece I will describe ionic liquids from a clinical point of view; specifically, I will evidence how ionic liquids may be important in the diagnosis industry. In a further piece, I will describe the surprising applications that ionic liquids have on the food and drinks industry.

What are ionic liquids?

Ionic liquids are salts constituted by large unsymmetrical organic cations and organic or inorganic cations. Due to this asymmetry they not easily form a crystalline structure and they are liquid salts at low (<100ºC) temperatures. The ionic character associated to ionic liquids is responsible for their negligible vapor pressure, non-flammability and high chemical and thermal stabilities. In addition, ionic liquids are recognized by their excellent solvation ability for a wide range of compounds and as a good stabilization media for biological molecules such as proteins. Moreover, ionic liquids are recognized as tunable designer solvents, a result of the possibility of choose the cation and anion constituents offering a large number of ion combinations and the possibility of designing specific solvents allowing the development of more effective extraction and purification platforms.

Ionic liquids in clinical and pharmacological fields

Aqueous biphasic systems (ABS) are, in general, two aqueous solutions of structurally different compounds separated into two coexisting phases where, above a given concentration, one of the phases will be enriched in one of the solutes and other in the second one. Below this concentration both phases are miscible. The mono- and biphasic region of each ABS is usually depicted in a phase diagram with a binodal curve separating the miscible and immiscible region.

Phase diagram example of an IL-based ABS.

The partitioning behaviour of a protein among the coexisting phases of an ABS is a complex phenomenon but a lot of attention has been given to the extraction, purification and concentration of proteins and other biomolecules of clinical interest using ionic liquids as phase-forming components of aqueous biphasic systems, in particular, a specific type of ionic liquids.

Proteins stability is highly affected by the pH of the medium and this specific type of IL show self-buffering capacity at pHs among 6-8. Being aware of this property, researchers developed a patent pending single-step platform to extract and concentrate prostate specific antigen (PSA), a prostate cancer biomarker. However, the PSA measurement requires the use of blood in a laborious and expensive techniques. Using ABS composed of ionic liquids lead to the total extraction of PSA to the ionic liquid-rich phase and, by reducing this one, it was concentrated samples of urine with PSA up to a factor that allows their measurement in a less expensive and laborious approach such as a simple HPLC analysis. In addition, HPLC analysis have shown that different PSA isoforms could be measured allowing the use of urine for primary or complementary prostate cancer diagnosis and evaluation, what can be a revolution in methodologies of cancer for early detection. There are a lot of cancer biomarkers, and by using specific ionic liquids, it could be possible to achieve a platform where a mixture of ILs is employed in an ABS composed of ionic liquids and urine to, in a single step, measure all of biomarkers related to each type of cancer. This will thus lead to a cheaper, non-invasive, and much more reliable early detection of cancer.

Besides, attention have also been given to the use of ionic liquids in pharmaceutical industries in the production segment as a way of reducing the use of environmentally hazardous and toxic organic solvents, and as a way of reducing the pollution, recovering drugs from wastes valuing them.

ABS composed of ionic liquids were found to be a successfully platform to extract morphine and the vasodilator papaverine (extraction efficiency of 96%).

Antibiotics, such as tetracycline, penicillin G or ciprofloxacin were also studied. In one investigation, penicillin G was extracted from a filtered fermentation broth with extraction efficiencies of 90%.

Studies regarding the purification and valorization of pharmaceutical solid wastes proposes new strategies to reuse them as an alternative to incineration. An integrated platform for the recovery of non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen and ketoprofen was conceptualized and involves 3 steps: extraction and purification of NSAIDs using IL three phase partitioning systems; precipitation of the drug using antisolvents; recycle and reuse of solvents. The results shown extraction efficiencies of approximately 84% and isolation efficiencies higher than 75 %, what are promising results not only because of the possibility of reuse and recycle the components, but also because of their low cost.

Energetic drinks are, without a question, one of the hottest topics in the food industry right now. However, in a time where a considerable fraction of the population shows stress symptoms, energy drinks might not be the answer your customer is looking for.

A relaxation drink is defined as a non-alcoholic beverage that contains calming ingredients. These drinks are growing in popularity and rely on the use of nutrients and herbs to reduce anxiety and promote relaxation. Sleeping drinks are also a growing trend in consumption, relying on slightly different natural components to induce the consumer a sensation of sleepiness and promoting a longer and more relaxed sleeping. Both types of drinks act by regulating a complex hormonal response in the consumer.

Stress, anxiety and sleep

Stress and anxiety are two major factors affecting the population. Stress is a condition arising from external physical or mental overload. It can make a person feel embattled, nervous, anxious or otherwise less capable of full and normal response to environmental demands.
Anxiety is a generalized mood of fear, worry and or uneasiness. It can be stimulated from environment factors, or result from bad habits or social situations. In developed countries, anxiety disorder rates range from 13.6% to 28.8% of the population. [1] The growing
urbanization, lack of exercise and stressful quotidian are bringing stress and anxiety to historical levels. Anxiety and stress may lead to insomnia, depression or even suicide.

Sleep plays a vital role in brain function and systemic physiology across many body systems. Problems with sleep are widely prevalent and include deficits in quantity and quality of sleep; sleep problems that impact the continuity of sleep are collectively referred to as sleep
disruptions. Disruption of sleep is widespread.

A 2014 survey conducted by the National Sleep Foundation reported that 35% of American adults rated their sleep quality as “poor” or “only fair”.

Trouble falling asleep at least one night per week was reported by 45% of respondents. In addition, 53% of respondents had trouble staying asleep on at least one night of the previous week, and 23% of respondents had trouble staying asleep on five or more nights. [2]

The hormonal regulation and possible ingredients for relaxation and improved sleep

Adaptogens are herbs that improve an individual’s ability to cope with stress and anxiety. These herbs normalize the physiological process of the body and help the body adapt to changes in times of increased stress, normally by reducing the serum cortisol levels, the stress hormone. A recent study discovered that Ashwagandha root extract safely improves an individual’s resistance towards stress and improves self-assessed quality of life by substantially lowering cortisol levels. [3] Other herbs, such as linden, hops or chamomille are also considered to be adaptogens in this regard. Chamomile is widely regarded as a mild tranquillizer and sleep inducer. Sedative effects may be due to the flavonoid apigenin that binds to benzodiazepine receptors in the brain. Studies in preclinical models have shown anticonvulsant and central
nervous system (CNS) depressant effects respectively. Clinical trials are notable for their absence, although 10 cardiac patients are reported to have immediately fallen into a deep sleep lasting for 90 minutes after drinking chamomile tea. [4]

According to American researchers [1], there are different types of anxiety that could be mild or sever depending on the level of the disorders. Using drugs is a common but harsh way to treat anxiety disorders. More natural treatments including amino acid, minerals, and fatty acids
ingestion can reduce anxiety and induce relaxation. Further, herbs and botanical medicine, such as St. John’s wort (Hypericum perforatum), Ginkgo biloba, Kava Kava, which have different roles to reduce many psychiatric disorders, also reduce anxiety.

In this regard, anxiety may be managed without the harsh side effects of pharmaceuticals using nutritional and botanical treatment as well as life-style changes.

Vitamins C, D, and E, omega-3 fatty acids, and the green tea amino acid L-theanine are dietary supplements known to increase the production of dopamine. Japanese researchers have found that the ingestion of 50 to 200mg of theanine promotes the generation of α-wavesin the brain some minutes after being ingested. α-waves have been studied as a relaxation index state in humans [5]. Theanine also lowers body temperature and blood pressure, two important factors in the relaxation process absent from drowsiness.

Drugs that alter serotonin levels are used in treating depression, generalized anxiety disorder and social phobia. Monoamine oxidase inhibitors (MAOIs) prevent the breakdown of monoamine neurotransmitters (including serotonin), increasing concentrations of the
neurotransmitter in the brain and promoting a sensation of relaxation and happiness. MAOI’s may be synthesized or natural. Herbs, spices and nutrients can inhibit MAO enzymes without the unpleasant side effects of antidepressants, examples being the nutmeg extract, the
passionflower, curcumin or black pepper extract. [6]

Herbs, spices and nutrients can inhibit MAO enzymes without the unpleasant side effects of antidepressants.

The sleep-wake cycle and its modulation

Both dopamine and serotonin play a non straightforward role in mammals’sleep-wake cycle and wakefulness/relaxation sensations. Dopamine can inhibit norepinephrine, causing the subject to feel more alert. Serotonin is involved in wakefulness, sleep onset, and preventing REM sleep.

Serotonin is required to produce melatonin, a hormone that plays a major role in sleep. The production and release of melatonin in the brain is connected to the time of day, increasing when it’s dark and decreasing when it’s light. Melatonin production declines with age.
Consumers use melatonin for sleep disorders, such as insomnia and jet lag. Unlike with many sleep medications, it does not promote dependency, habituation or experience a hangover effect. It is available as an ingredient for food and drink fortification. Melatonin can be used to treat delayed sleep phase and circadian rhythm sleep disorders in the blind and provide some insomnia relief. Valerian root extract is also a major sleep promoter, safely administered in food and pill forms.

Further, supplementation with the amino acid L-tryptophan and its precursor, 5-HTP, and the B vitamins, vitamin D, selenium, and omega-3 fats increases serotonin production. Tryptophan may increase agreeableness, decrease quarrelsomeness and improve mood. Although purified tryptophan increases brain serotonin, foods containing tryptophan do not. This is because tryptophan is transported into the brain by a transport system that is active towards all the large neutral amino acids and tryptophan is the least abundant amino acid in protein. α-Lactalbumin, a minor constituent of milk, is one protein that contains relatively more tryptophan than most proteins, and milk brands are taking advantage of this situation to incorrectly claim that milk promotes a better sleep through tryptophan ingestion.

Gamma-aminobutryric acid (GABA) is a major chemical signalling molecule in the process of relaxation/sleepiness and is becoming a trendy ingredient in the food industry. A randomized, single-blind, placebo-controlled crossover-designed study was conducted to evaluate the effect of GABA on sleep. Sleep was evaluated by electroencephalography (EEG) after oral GABA administration. GABA significantly shortened sleep latency and increased the total non-rapid eye movement (non-REM) sleep time. Questionnaires showed that subjects receiving GABA realized its effects on sleep. [7] Dietary GABA supplement in clinical studies relieves anxiety and increases alpha brain waves, which are associated with relaxation.

The bottom line

The sensation of relaxation and sleeping promotion are interconnected. However, some ingredients, whether natural or synthetic, may be more adequate for a specific application, and regulatory laws may soon be imposed in incipient markets. In a further piece we will explore how regulatory laws may be applied to this sector and the market size for this type of innovative drinks.

Bone broth is made by simmering animal bones and tissue for at least 8 hours with optional vegetables, herbs, spices and salt.

The health benefits of bone broth (or soup) have been long perceived, but only a decade ago was the remedial effect of bone broth scientifically evaluated. For instance, the generally believed curing effect of chicken soup against symptomatic upper respiratory tract infection has been found to follow from an increase in nasal mucus velocity or its mild anti-inflammatory effect.

More recently, bone broth has been increasingly recommended as part of the diets for gut and psychology syndrome (GAPS) patients, such as those with autism and attention-deficit hyperactivity disorder (ADHD). Brand owners and marketeers are supporting the growth of bone broth as a functional product by claiming that it can quell inflammation, speed healing, calm allergies, combat fatigue and promote satiety. These attributes could be attributed to broth’s protein, collagen, gelatin, essential and inessential aminoacids and minerals. Several media and academic references support the positive attributes of bone broth, as shown below:

The Nourished Kitchen – Bone broths are extraordinarily rich in protein, and can be a source of minerals as well. Glycine supports the bodies detoxification process and is used in the synthesis of hemoglobin, bile salts and other naturally-occurring chemicals within the body. Glycine also supports digestion and the secretion of gastric acids. Proline, especially when paired with vitamin C, supports good skin health.

Kettle and Fire – Bones and connective tissue are storehouses for essential amino acids and minerals — which are lacking in many diets today. Bone broth is also an invaluable source of protein, collagen and gelatin.

Medical News Today – Drinking bone broth may be beneficial for the joints and digestive system, among other things. Bone broth is highly nutritious, may protect the joints, may help fight osteoarthritis, may help reduce inflammation and heal the gut, may aid sleep and may support weight loss.

Cognitune – Enhancement of weight loss and metabolism, with fantastic properties regarding detoxification, digestion and weight loss.

A 2017 research study included bone broth as part of a recommendable microbiome restoration procedure.

Brand owners and marketeers are supporting the growth of bone broth as a functional product by claiming that it can quell inflammation, speed healing, calm allergies, combat fatigue and promote satiety. However, the topic is controversial.

On a 2016 piece titled ‘Science Can’t Explain Why Everyone is Drinking Bone Broth’, Time Magazine claims that ‘there isn’t much research on bone broth to support—or refute—these health claims. But several experts on human digestion say the nutrients that supposedly make
bone broth special are not, in fact, all that unique.’ A recent australian research paper advises that ‘If the intake of collagen precursors is proven to support the synthesis of new collagen in vivo, it’s unlikely that bone broth can provide a consistently reliable source of key amino acids.’ More research is needed, and while no source claims its unhealthiness, bone broth seems to contain a fair concentration of protein and minerals, promoting satiety and a warmth feeling. However, it may not be delivering the remarkable nutrition that some entities are claiming, especially due to bioavailability issues and insuficient concentration of the key nutritional compounds for a superior level of functionality.

Evidences seem to suggest that the longer the cooking, the more gelatin and minerals are extracted, a key goal while producing bone broth. The extended cooking promotes the release of aminoacids from bones.

Production of bone broth

While any bone or ligament can be used, knuckles, chicken feet, and femur bones tend to contain the most collagen. Beef, chicken and fish are the most used animals for bone broth production. As with stock, bones are typically roasted first to improve the flavor of the bone
broth. The bones may contain a small amount of meat adhering to them. At the end of cooking, the bones should crumble when pressed lightly between the thumb and forefinger. While the bone broth is being prepared, proteinaceous foamy scum typically bubbles up at the
top of the pot. Removing it helps to clarify the broth and improve its flavor. At the end of the desired time of cooking, the bones and other debris are discarded and the remaining liquid can be filtered or strained for higher purity. After conditioning the final liquid in the fridge, the
natural fat from the broth is typically removed, yielding a brown coloured liquid with a turbid look. The final product is microbiologically unstable, so that a pasteurization/sterilization cycle will be needed to increase the shelf-life of commercial liquid bone broths. The pasteurized broth may display a shelf-life of over 2 years. Optionally, the broth may be dehydrated to a powdered form, allowing for its posterior reconstitution with boiling water.

A growing market for bone broth

According to figures from Global Market Insights, Inc, global broth market is projected to exceed USD 2.8 billion by 2024; according to a new research report by Global Market Insights, Inc. changing consumer preference towards animal-based stock as a protein source will drive broth market growth. Rising health consciousness and high disposable income will support the product penetration. Factors such as rapid urbanization and ageing population are anticipated to propel ready to drink broth market size.

North America broth market will witness growth over 4% up to 2024. High disposable income and trend of ready to eat food due to changing lifestyle will propel regional industry size. Increasing consumer consciousness regarding health benefits associated with stock
consumption over traditional soups will fuel product penetration. Asia Pacific broth market size accounted for over 15% of the industry share in 2016. The regional industry growth is attributed  to large consumer base and increasing spending on packaged food. Increasing working women population in the region is also likely to influence product demand. Development of multi outlet food channels will drive convenient buying of products thus, propelling regional industry growth.

Growing awareness regarding personal fitness among young and adults will fuel broth market size. Improved metabolism, bone strength and enhanced immunity are the key health benefits offered by the product. Increasing popularity of rich nutrient beverages to avoid dependency on medicines and health supplements will provide lucrative opportunities for the industry growth.
