During a coronary virus pandemic, scientists pay special attention to the state of the human immune system, which should serve as a reliable antiviral barrier and prevent the development of the disease. Numerous clinical trials have shown that probiotic lactic acid and propionic acid bacteria are able to increase the body's resistance to certain diseases through immunostimulatory action. Probiotics play an important role in support of colonization resistance, providing pronounced antagonistic activity against pathogenic microorganisms, producing various organic acids, hydrogen peroxide, antibiotics and bacteriocins. Producing highly active hydrogen peroxide, some lactic acid bacteria have a pronounced viral effect. Promoting the production of antibody cytokines in the intestine, they stimulate the synthesis of interferon by gamma lymphocytes, as well as increase the activity of phagocytes and natural cells-killers (NK cells). Immunomodulatory properties of lactic acid bacteria are able to balance the imbalance in immune reactions that cause allergies. They also have a positive effect on cholesterol blood serum.

Modern science offers dairy producers unique combined protective cultures that provide probiotic properties to fermented milk products and prevent the development of unwanted microflora, maintaining shelf life. Protective probiotic yeasts of the ASTRO series Italian manufacturer CALZA CLEMENTE contains strains of lactobacilli - L. rhamnosus, L. plantarum, L. paracasei, which show an antagonistic effect against technically harmful and pathogenic microflora. These strains do not affect the activity of beneficial lactic acid bacteria, improve the taste and aroma of products, eliminate foreign tastes of milk, allow you to get "initially fresh" products, even at the end of storage. Propionic acid bacteria P. Freudenreichii, which are part of the protective culture of ASTRO-LP, have a powerful immunomodulatory and antimutagenic effect. These bacteria are able to take root in the intestines of humans and reduce the toxic effects of a number of chemical compounds and UV rays. Unlike other probiotic bacteria, propionic acid bacteria are capable of significant synthesis of corinoids and antioxidant enzymes. P. freudenreichii bacteria block the action of carcinogens and tumor growth promoters.

In total, the application of protective probiotic cultures ASTRO allows manufacturers to produce truly healthy dairy products, standardize their production process, extend shelf life, reduce economic losses, reach a new level of quality and brand recognition.
