Summer style is healthy, and new guests dominate fashion.
In recent years, with the enhancement of people's health awareness, the health care concept of "medicine is better than food" has gradually taken root in people's hearts. Whole wheat cake, nourishing porridge, nourishing soup and herbal tea are increasingly becoming "guests" in dining and leisure time. Yogurt with unique taste and flavor is quickly promoted to the top of daily health care because of the addition of probiotics with different effects.
A large number of documents at home and abroad show that yogurt is fermented from pure milk. Lactic acid bacteria can not only retain all the nutrients of fresh milk, but also produce various vitamins necessary for human nutrition during fermentation. Its lactic acid can effectively improve the utilization rate of trace elements such as calcium and phosphorus.
Authoritative experts said that adding probiotics with various functions would add icing on the cake to yogurt. According to the definition of probiotics given by the European Food and Feed Strain Association in 2003, probiotics refer to microorganisms that can produce one or more functional health benefits when ingested in sufficient quantities. The main types of probiotics are Lactobacillus acidophilus, Bifidobacterium, Lactobacillus casei and Lactobacillus rhamnosus. Experts say that these probiotics have specific health care effects after experimental demonstration, characterized by strong acid resistance and can reach the intestine alive. The function of common lactic acid bacteria is to ferment milk into yogurt, which contributes to the taste and structure of yogurt. However, when passing through the digestive tract, ordinary yoghourt bacteria are not the normal flora of human intestine, and are very sensitive to gastric acid and bile, and cannot withstand the killing effect of gastric acid and bile, and cannot enter the intestine alive. Even if a small amount can enter the intestine alive, it cannot be colonized in the intestine and will be excreted quickly, so the health care function is limited.
Some professional researchers abroad emphasize that 1 00000 ~ 1 100 million probiotics /ml is an ideal level, which is called "minimum therapeutic dose" in the literature, that is, the minimum amount of live bacteria that consumers should consume every day is1100 million. Relevant data show that the current national standard of yogurt is very loose: as long as the number of active lactic acid bacteria in the product reaches 1 10,000 /ml, it can be called yogurt. Some developed countries have specially formulated effective intake regulations, such as the regulations of Japan Fermented Milk and Lactic Acid Bacteria Beverage Association: every milliliter of fresh dairy products must contain at least100000 Bifidobacterium; The nya Association of the United States stipulates that at least 65.438+0 billion lactic acid live bacteria /ml can be used to use nya's "live bacteria" mark.

What is the unique charm of tiny and wonderful probiotics, attracting countless dairy manufacturers and consumers to compete for production and purchase? Associate Professor Ding, who has been engaged in clinical research and practice of traditional Chinese medicine for many years, pointed out that probiotics are called "microecological regulator" or "intestinal flora imbalance regulator" in clinical pharmacology. They are widely used in clinic, which helps to restore normal intestinal flora, increase appetite and reduce the release of endotoxin from harmful intestinal bacteria to some extent.
Moreover, yogurt with different kinds of probiotics has different effects. Shanghai Institute of Preventive Medicine, Nanjing Medical University and other national authorities have conducted evaluation tests on the immune function enhancement effect of Guangming Jianneng ab 100 probiotic yogurt (rich in ab 100 probiotics-Lactobacillus acidophilus and Bifidobacterium, referred to as "ab bacteria"). The results of cellular immune function, humoral immune function and nk cell activity test show that it can improve the nonspecific immune response of human body, increase the content of immunoglobulin, have the health care function of enhancing immunity, and obtain the "health" certificate issued by the state.
The reason why Guangming e probiotic yogurt has health care functions such as regulating intestinal flora is also closely related to its rich E flora (Lactobacillus bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus and Bifidobacterium). After strict screening and scientific testing, E probiotics have strong acid and bile tolerance, and can be successfully colonized in the intestine through the gastrointestinal environment.
Bright Changyou's function of "regulating gastrointestinal function and helping to moisten intestines and relieve constipation" is also mainly attributed to the addition of "b 100" probiotics. A large number of experimental data show that compared with similar probiotics, "b 100" is more suitable for living in the intestine, promoting the balance of immune system, creating an environment that is not conducive to the growth of pathogens, maintaining the natural immune protection system, providing a suitable environment for the growth of lactic acid bacteria and bifidobacteria, promoting the growth and development of beneficial bacteria in the intestine, inhibiting the growth and reproduction of spoilage bacteria and harmful flora, maintaining the ecological balance of intestinal flora, and helping to reduce gastrointestinal dysfunction.
Experts say that some high-end yogurts without special probiotics can also have special functions if the technological formula is scientific. This is the case with Bright Korean Herbal Yogurt, which does not use probiotics, but only uses ordinary yogurt fermentation bacteria (including Streptococcus thermophilus and Lactobacillus bulgaricus). However, based on the addition of herbal essence crystals with oriental health care characteristics, yogurt not only has a unique taste, but also has different meanings because of additives.
It is reported that there are three kinds of Chinese herbal yoghourt blooms in beauty beauty, which are nourishing stomach, clearing away heat and reducing fire, and moistening face, and their effects are recorded in China People's Pharmacopoeia (2000 edition).
At the same time, experts suggest that health food or functional yogurt cannot replace medicines. If the patient's symptoms are serious, he should go to a medical institution in time, make scientific arrangements and make persistent dietary adjustments.
Dazzling on-demand choices cannot be blurred.
Hot summer has always been the season of yogurt sales. With all kinds of probiotic yogurts rushing to the market, many consumers are at a loss in the face of dazzling shelves.
Relevant experts specially reminded that buying yogurt, especially probiotic yogurt, requires "three looks". Look at the manufacturer and probiotic varieties, and buy as needed. Compared with ordinary yogurt, the price of probiotic yogurt is higher, so consumers should pay more attention to the manufacturers and probiotic varieties on the product packaging when choosing. The former determines R&D strength and trust in products, while the latter determines whether the efficacy of products meets their own needs. Consumers should pay attention to the strains on yogurt packaging according to their own or family needs: if they want to improve their immunity, choose "Jianneng ab 100" probiotic yogurt; If you want to regulate the stomach, then "e" probiotic yogurt can meet the demand; If you care about detoxifying and relaxing bowels, "Changyou" yogurt can help you realize your wish.
The probiotic yogurt produced by Guangming Company is supported by the leading national technology center in Asia, and now it has a variety of independent innovation strains. Among them, Lactobacillus casei strain lc2w and its application in preparing antihypertensive products (zl 03 129450.2), Lactobacillus casei strain bd-ii and its application in regulating blood lipid (zl 03 128995.9), Lactobacillus plantarum strain st-iii and its application in regulating blood lipid (ZL 03128995.9)
The second choice of yogurt depends on whether the cold chain is perfect. Yogurt should be refrigerated at 2℃~6℃, otherwise it may lead to the reproduction of harmful microorganisms such as yeast, make it deteriorate and can no longer be eaten. Yogurt should also be stored in the refrigerated layer of the refrigerator after being bought back, but not in the frozen layer to prevent the organizational state of yogurt from being destroyed.
Third, look at the shelf life of yogurt. Pay attention to products near the end of shelf life. Do not eat yogurt once it is found to be swollen or the product has obvious abnormal state such as water-milk separation after opening.
Five things to remember when drinking. First, don't drink yogurt after an empty stomach or strenuous exercise. Consumers with weak gastrointestinal function can take the yogurt out of the refrigerator about half an hour before eating, and then eat it at room temperature to avoid the stimulation of the low temperature of yogurt on the gastrointestinal tract. Second, yogurt should be eaten as soon as possible after opening. Please seal the unused yogurt and store it in the refrigerator again. It is suggested that the yogurt after opening should be drunk within one day. Third, yogurt can't be heated for drinking, or a large number of active lactic acid bacteria and probiotics contained in it will be killed, which will not only lose its nutritional value and health care function, but also change the physical properties of yogurt, form precipitation and disappear its unique taste. Fourth, it should not be taken at the same time as antibiotics. Antibiotics such as chloramphenicol and erythromycin and sulfonamides can kill or destroy lactic acid bacteria in yogurt, making it lose its health care function. Fifth, rinse your mouth in time after drinking. Because lactic acid has a certain corrosive effect on teeth, gargling or using straws in time can reduce the chance of lactic acid contacting teeth.
