Beer with probiotic
Scientists have created beer with beneficial intestinal bacteria
Anatoly Alizar, Geektimes, based on the materials of the National University of Singapore: NUS researchers create novel probiotic beer that boosts immunity and improves gut health
As you know, the systematic use of beer leads to the development of alcoholism. This drink has all the same harmful effects as other alcoholic beverages. In addition, according to the WHO, beer consumption increases the risk of colon cancer. That is, beer and a healthy intestine are seemingly incompatible things. But scientists from the National University of Singapore intend to change this situation to the opposite. They brewed beer, which is not harmful to the intestines, but on the contrary, it is good for him!
A group of researchers by fermentation obtained an alcoholic drink containing a probiotic strain – the bacterium Lactobacillus paracasei L26 (L26). According to some studies, it neutralizes toxins and viruses in the body, as well as improves intestinal health and increases immunity.
Probiotics are by definition good for the body. Probiotics are a class of microorganisms and substances of microbial and other origin used for therapeutic purposes, as well as food products and biologically active additives containing live microcultures. In other words, all beneficial microorganisms and food ingredients with microorganisms are commonly called probiotics. Most often, their use is to normalize the composition and (or) increase the biological activity of the normal intestinal microflora.
The scientific literature describes the beneficial effect of the bacterium Lactobacillus paracasei L26 on the human body, including the role of L26 in increasing immunity, although there is no generally recognized scientific concept on this score, and the same FDA does not recognize probiotics as medicines.
In general, many people have little idea how much influence the intestinal microflora has on the overall health of the body. Scientists have proved that microflora affects not only the immune system and a number of key body systems, but it even affects the functions of the higher nervous system! For example, the intestinal microflora affects a person's mood, can contribute to a bad mood, up to depression. It all depends on the composition and harmonious compatibility of bacteria, of which there are about 2 kilograms or 50 trillion individual organisms living in symbiosis with a carrier (human) in the intestine.
Although numerous studies show the benefits of consuming probiotics, these bacteria are rarely found in everyday foods. For example, they are in some yogurts. But the same yogurts have recently raised many questions among healthy nutrition experts in connection with cholesterol, allergens and lactose intolerance. Thus, the question arises, what alternative methods can be used to introduce probiotics into the body. Singapore scientists believe that the ideal option is beer.
Beer with probiotics was first brewed for her graduation project by Alcine Chan, a student of the last fourth year of the Faculty of Food Science and Technology at the National University of Singapore. She is a big fan of probiotics herself and takes them daily. Now it will be easier for her to do this: instead of yoghurts and other products, it is enough for Alsina to drink a 100-gram glass of self–brewed beer, or two: "Although good bacteria are often present in fermented food, but there has not been beer with probiotics on the market so far," says the inventor. –Breeding enough live probiotics in beer is a problem because there are hop acids in beer that prevent the growth and survival of probiotics."
Together with her supervisor, associate professor Liu Shao-Quan, the student perfected the brewing process for nine months before she received the perfect recipe.
During the tests, six strains of probiotics were tested, and L26 proved to be the most resistant to hop acids. Scientists have optimized the temperature, time and ingredients that are used in the fermentation process to ensure the steady growth of probiotics.
Every 100 ml of Singapore beer contains about 1 billion beneficial bacteria. This is the norm recommended for daily consumption by the International Scientific Association of Probiotics and Prebiotics. Naturally, beer is not filtered and pasteurized to preserve the living microflora. It has a standard alcohol content of about 3.5%. Student Alsina Chan and associate professor Liu Shao-Kuan assure that beer also has a pleasant "sharp and tart aroma".
The inventors have already filed a patent application for a new variety and recipe of beer. They hope for cooperation from the world's largest breweries. So soon a useful "beer with live bacteria" may appear on the shelves of our stores. At least someone will have an excuse in front of his wife: they say, I didn't want to drink, but what to do is necessary for health, I had to force myself.
Well, Mrs. Chan will receive a well-deserved bachelor's degree from the National University of Singapore in July 2017, and not just a simple one, but with honors (the highest degree of recognition).
