Freshly pressed milk beverage containing fructo-oligose-anthocyanin and preparation method of freshly pressed milk beverage

Abstract

The invention belongs to the technical field of functional drink preparation and particularly relates to freshly pressed milk beverage containing fructo-oligose-anthocyanin and a preparation method of the freshly pressed milk beverage. The freshly squeezed milk beverage is prepared from the following components in parts by weight: 30-50 parts of ultra-fine cold pressed peanut meal powder, 30-50 parts of rock candy, 70-90 parts of fructo-oligose, 10-20 parts of maltose, 0.1-0.5 part of salt, 0.08-0.16 part of citric acid and 50-80 parts of black chokeberry juice, and a soluble soybean polysaccharide which is 0.2-0.5% of total weight is added. Through adding the ultra-fine cold pressed peanut meal powder to the black chokeberry juice, the ingredients, such as revertose contained in cells, multiple amino acids, metal elements, unsaturated fatty acid and isoflavone are fully exposed and dissolved into the black chokeberry juice due to cell lysis of a peanut powder sample, and through addition of 10% fructo-oligose, the stability of the anthocyanin in black chokeberry juice drink is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of functional beverage preparation, and in particular relates to a raw milk beverage containing fructooligosaccharide-anthocyanin and a preparation method thereof. Background technique [0002] Cold-pressed peanut meal is a by-product of low-temperature cold-pressed peanut oil. Because the low temperature damages less active ingredients such as polysaccharides and proteins, it has good functional properties and high development and utilization value. Peanut cold-pressed meal contains a lot of protein, and each component contains 18 kinds of amino acids, the content of unsaturated fatty acids is very high, it contains a variety of vitamins and it is difficult to obtain copper, magnesium, potassium, calcium, zinc, selenium from other foods , iodine and other elements; peanut meal is also rich in isoflavones, antioxidants and other plant active compounds. [0003] Anthocyanin is a kind of pigment widely used i...
