Whey protein solid beverage containing N-acetylneuraminic acid and preparation method thereof

Abstract

The invention discloses a whey protein solid beverage containing N-acetylneuraminic acid. The beverage is prepared from sugar, concentrated whey protein powder, whole milk powder, N-acetylneuraminic acid, probiotics, prebiotics, ethylenediaminetetraacetic acid ferric sodium salt and casein phosphopeptides. According to the whey protein solid beverage, all raw materials are effectively combined, the immunity of all kinds of people including infants and young children can be effectively enhanced, the whey protein content is high, nutrition is rich, absorption is facilitated, and more sufficientnutrition and energy can be provided for drinkers.

Description

technical field [0001] The invention relates to a solid beverage and a preparation method thereof, in particular to a whey protein-based solid beverage containing N-acetylneuraminic acid and a preparation method thereof, belonging to the field of food. Background technique [0002] Whey protein is a protein extracted from milk, mainly composed of β-lactoglobulin, α-lactalbumin, bovine serum albumin, immunoglobulin, etc. Among the more than 20 kinds of amino acids contained in it, there are 8 kinds necessary for the human body Amino acid, its protein potency, biological potency and protein net utilization rate are all better than casein and soybean protein. At the same time, whey protein is rich in cysteine ​​and methionine. These sulfur-containing amino acids can maintain the level of antioxidants in the human body and try to stabilize DNA during cell division. Experiments have shown that whey protein can also stimulate the human immune system, prevent chemical substances f...

AI Technical Summary

Problems solved by technology

Composed of fructo-oligosaccharides or fructose, soybean lecithin, sodium caseinate, low-fat pectin and other ingredients, the main components in the formula are water-soluble dietary fiber and protein powder, the main function is to replace meals for weight loss, to supplement nutrition and vitamins, There is no mention of improving eyesight, supplementing physical fitness, etc.

Moreover, existing whey protein solid beverages also have problems such as uneven dispersion and rough mouthfeel when brewing with water.

[0004] The main reason is that the heat sterilization process of whey beverage in the production process can easily lead to denaturation of whey protein, easy to produce floc precipitation, and it is difficult to ensure the stability of protein during the normal shelf life; in addition, as a liquid beverage, When the content of whey protein in it is high, for example, if the content of whey protein in the beverage reaches 0.1wt% or higher, it will also bring peculiar smell (fishy smell) to the beverage, and the excessive content will also increase the viscosity of the beverage , causing the problem that the taste of the drink is not refreshing
