Kefir is a complex fermented dairy product created through the symbiotic fermentation of milk by lactic acid bacteria and yeasts contained within an exopolysaccharide and protein complex called a kefir grain. As with other fermented dairy products, kefir has been associated with a range of health benefits such as cholesterol metabolism and angiotensin-converting enzyme ACE inhibition, antimicrobial activity, tumor suppression, increased speed of wound healing, and modulation of the immune system including the alleviation of allergy and asthma. These reports have led to increased interest in kefir as a focus of research and as a potential probiotic-containing product.

Milk ke fi r : nutritional , microbiological and health bene fi ts

Kefir is fermented milk produced from grains that comprise a specific and complex mixture of bacteria and yeasts that live in a symbiotic association. Kefir originates from the Caucasus and Tibet. Recently, kefir has raised interest in the scientific community due to its numerous beneficial effects on health. Currently, several scientific studies have supported the health benefits of kefir, as reported historically as a probiotic drink with great potential in health promotion, as well as being a safe and inexpensive food, easily produced at home. Regular consumption of kefir has been associated with improved digestion and tolerance to lactose, antibacterial effect, hypocholesterolaemic effect, control of plasma glucose, anti-hypertensive effect, anti-inflammatory effect, antioxidant activity, anti-carcinogenic activity, anti-allergenic activity and healing effects. A large proportion of the studies that support these findings were conducted in vitro or in animal models. However, there is a need for systematic clinical trials to better understand the effects of regular use of kefir as part of a diet, and for their effect on preventing diseases.

After fermentation, free amino acids were Glutamic acid was majority in both, suggesting that microbial proteolysis leads to an increase in free amino acids including glutamic acid. Lactococcus lactis , Kazachstania unispora , and Saccharomyces cerevisiae were isolated as major microorganisms in both kefirs. Both kefirs also exhibited antioxidant activity and bactericidal activity against Escherichia coli , Salmonella Typhimurium, and Staphylococcus aureus. Kefir is a fermented beverage consumed since ancient times that presents typical flavour characteristics through the presence of lactic and acetic acids, ethanol, and carbon dioxide. Several health-promoting properties have been associated with kefir consumption [ 1 ], and various properties including antitumor, antibacterial, antioxidant, antifungal, antimutagenic, and hypocholesterolaemia have been demonstrated [ 2 — 4 ].

Seven benefits of kefir

There is a huge demand for food-derived polysaccharides in the field of materials research due to the increasing concerns posed by synthetic biopolymers. The scientific community is extensively searching for other natural, food-derived or bio-inspired polymers that possess promising potentials and advantageous properties that can be promptly utilized for multifarious applications. Kefiran, a food-derived microbial exopolysaccharide extracted from kefir grains has exhibited evidence of non-toxicity, anti-microbial activity, nutritional value, and other favourable characteristics. This review aims to shed light on the properties of kefiran and provide an overview of its applications in the agri-food and biomedical sectors. The present work also discusses the challenges and prospects that lie ahead for kefiran in finding its place amongst the existing spectrum of natural and biodegradable polymers.

Kefir's History. Kefir dates back many centuries to the shepherds of the Caucasus mountains. They discovered that fresh milk carried in leather pouches would occasionally ferment into an effervescent beverage.

Мгновение спустя, словно в дешевом фильме ужасов, свет в ванной начал медленно гаснуть. Затем ярко вспыхнул и выключился. Сьюзан Флетчер оказалась в полной темноте. Сьюзан Флетчер нетерпеливо мерила шагами туалетную комнату шифровалки и медленно считала от одного до пятидесяти. Голова у нее раскалывалась.

Сьюзан прочитала открывшееся сообщение, которое состояло из одной строчки, потом прочитала его еще. ПООБЕДАЕМ У АЛЬФРЕДА. В 8 ВЕЧЕРА. В другом конце комнаты Хейл еле слышно засмеялся. Сьюзан взглянула на адресную строку сообщения. FROM: CHALECRYPTO. NSA.

Как он поведет машину, если они все же доберутся до. И тут в его памяти зазвучал голос одного из преподавателей Корпуса морской пехоты, подсказавший ему, что делать. Применив силу, говорил этот голос, ты столкнешься с сопротивлением. Но заставь противника думать так, как выгодно тебе, и у тебя вместо врага появится союзник. - Сьюзан, - услышал он собственный голос, - Стратмор - убийца. Ты в опасности.

Тогда Стратмор напрягся и рванул тело изо всех сил. Внезапно его швырнуло назад, и он больно ударился спиной о кожух генератора. Пытаясь подняться на ноги, Стратмор в ужасе смотрел на предмет, зажатый в его пальцах: это была рука Чатрукьяна, обломившаяся в локтевом суставе.

Очередь из десяти человек, толкотня и крик. Испания не славится эффективностью бюрократического аппарата, и Беккер понял, что ему придется простоять здесь всю ночь, чтобы получить информацию о канадце. За конторкой сидела только одна секретарша, норовившая избавиться от назойливых пациентов.

Где-то в темноте, казалось, прямо над ними, послышались пронзительные гудки. Стратмор повернулся, и Сьюзан сразу же его потеряла. В страхе она вытянула вперед руки, но коммандер куда-то исчез.

На ней стояли пустая бутылка из-под шампанского, два бокала… и лежала записка. Протерев глаза, она натянула на плечи одеяло и прочла: Моя драгоценная Сьюзан. Я люблю .
