Pure milk is one of the oldest natural beverages and is called 'white blood'. The preservation rate of the nutrient components in the sterilized fresh milk is usually more than 90%. Milk and its products are one of the important sources of protein, calcium, phosphorus, vitamin A, vitamin D, vitamin B2, etc. in the diet, contain a large amount of bioactive substances, have high nutritive value and are easy to digest and absorb. However, not only humans, but also animals, suffer from lactose intolerance. Lactose intolerance is a condition in which the patient's intestinal tract cannot secrete lactose-decomposing enzymes, but cannot digest and absorb lactose for use by the body, which is likely to cause diarrhea, abdominal distension, etc.
Pectin oligosaccharide is a low molecular carbohydrate, has a plurality of bioactive functions, and as a novel functional oligosaccharide, the excellent prebiotic property attracts more and more attention and researches, particularly the regulation effect on intestinal flora. At present, researches show that pectin oligosaccharide can reduce the number of bacteroides and clostridia and participate in growth regulation and adhesion processes of bifidobacteria in intestinal tracts, thereby reducing secretion of exotoxin and invasive enzymes, and particularly having good prevention effect on pseudomembranous colitis. The pectin oligosaccharide is also a natural bacteriostatic preservative, and can effectively inhibit or even kill putrefying bacteria in food and beverage, thereby playing a role in prolonging the shelf life of the food and beverage.
