Problems solved by technology

Among them, glucose and fructose are reducing, adding fructo-oligosaccharides will increase the content of reducing sugars, causing the strengthening of the Maillard reaction, so fructo-oligosaccharides in liquid milk, especially UHT sterilized pure milk or pasteurized milk The application is limited, usually the amount of fructo-oligosaccharide added per milliliter of milk does not exceed 2 mg, and there is no process for adding fructo-oligosaccharide to liquid milk while controlling the fururine content

Abstract

The invention discloses a liquid milk product and a preparation method thereof. The liquid milk product contains 5 to 24 milligrams per milliliter of fructo-oligosaccharide. The preparation method comprises the following steps: adding the fructo-oligosaccharide and then performing sterilization, wherein raw milk is added with the fructo-oligosaccharide after being cooled to a temperature of between 10 and 20 DEG C. The liquid milk product not only is rich in active prebiotics, namely the fructo-oligosaccharide, but also is low in furoic acid, thus the liquid milk product has mellow mouth feel, can promote the absorption of the mineral substances of Ca, Mg and the like and the proliferation of intestinal probiotics groups, and regulate the function of intestinal tracts.

Description

technical field [0001] The invention belongs to the field of liquid milk, in particular to a liquid milk product and a preparation method thereof. Background technique [0002] Fructooligosaccharides (FOS), also known as fructooligosaccharides or fructooligosaccharides, is a mixture of kestrose (GF2), kestotetraose (GF3) and fructopentose (GF4) (wherein G is Glucosyl, F is fructosyl). Fructose-oligosaccharide is a natural active substance with many physiological and health functions: promoting the proliferation of intestinal probiotics and improving intestinal function; promoting the absorption of calcium, magnesium and other minerals; improving the body's immunity; improving lipid metabolism; reducing blood lipids and Cholesterol, etc., is considered to be one of the "prebiotics". And the taste of fructooligosaccharides is pure, sweet and delicious, with a fat-like fragrance and refreshing creamy feeling. At present, the oligosaccharide project has been listed as a key r...
