Lactobacillus casei, as a kind of probiotic bacteria, can tolerate the defense mechanism of the organism, including enzymes in the oral cavity, low pH in gastric juice and bile acids in the small intestine. Therefore, after entering the human body, Lactobacillus casei can survive in the intestine in a large amount, which plays a role in regulating the balance of intestinal flora and promoting the digestion and absorption of the human body. At the same time, Lactobacillus casei has the functions of efficiently lowering blood pressure and cholesterol, promoting cell division, producing antibody immunity, enhancing human immunity and preventing cancer and inhibiting tumor growth; it also has a unique health function of probiotics, which can help digestion and prevent Constipation and aging of cells, anti-tumor and regulate body functions. It also has probiotic health care effects such as alleviating lactose intolerance and allergies. Because Lactobacillus casei has a significant probiotic effect on its host nutrition, immunity, disease prevention, etc., it has increasingly become the focus of people’s research, development, and production. With the increase of hypertensive people, the research on Lactobacillus casei and the use of it to develop functional dairy products are of great significance.
Lactobacillus casei can also inhibit and kill many spoilage bacteria and pathogenic bacteria in food, and does not affect food properties, and can even improve food characteristics, so adding it as a starter to food can make the product more high-quality and Antiseptic preservation during food storage also plays a positive role.
