Description

High-protein modified milk and preparation method thereof Technical Field The invention belongs to the technical field of foods, and relates to a high-protein modified milk and a preparation method thereof. Background With the increasing aging of the global population, health problems of middle aged and elderly people are increasingly concerned. In terms of diet, the middle-aged and elderly people have unique eating habits and nutritional requirements. From the aspect of eating habits, the daily intake and the daily frequency of the middle-aged and elderly people in China are relatively small, and the people are contraindicated for cold food, and the main reason for forming the habits is based on the consideration of personal health and mainly preventing diseases. In terms of nutrition requirements, the middle-aged and elderly people have special requirements for nutrients such as proteins, vitamins, minerals and the like. For example, protein intake is positively correlated with muscle mass and strength, and many elderly people have significantly reduced muscle mass and strength due to insufficient protein intake, and the loss of muscle tissue and even visceral tissue in the extremities results in reduced body multi-system function. Meanwhile, the middle-aged and elderly people have higher requirements on improving intestinal health, strengthening bones, maintaining cognitive health and other functions. The food and beverage products aimed at middle-aged and elderly people in the market are numerous and can be roughly divided into dairy products, such as milk powder, liquid milk and the like for middle-aged and elderly people, which are high in calcium and protein and rich in vitamins, cereal beverages, such as pulp beverages prepared from coarse cereals, which are natural, healthy and digestible, functional beverages, such as products with added probiotics, dietary fibers and the like, which are declared to improve intestinal functions and regulate blood sugar and blood fat, and medicine and food homologous beverages, which are combined with traditional health maintenance concepts and added with food materials, such as medlar and Chinese yam. But the high-protein modified milk products which are specially used for meeting the special nutritional requirements of middle-aged and elderly people and are excellent in all aspects are still to be perfected. The existing product mainly contains casein, the digestion capacity of middle-aged and elderly people is reduced, a large amount of casein is difficult to digest, and the lactose intolerance of middle-aged and elderly people is obviously higher in proportion. Most products only strengthen single protein of animals or plants, neglect the collocation combination of animal and plant proteins and the requirement of the old on nutrients such as different amino acids, dietary fibers and the like, and the high protein addition easily causes thick milk products, heavy powder quality, influences drinking experience and is not easy to swallow. Therefore, it is highly desirable to provide a high protein milk blend suitable for digestion and absorption by middle-aged and elderly people, which meets the nutritional requirements and has better drinking experience and product stability. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide high-protein modified milk and a preparation method thereof. In order to achieve the aim of the invention, the invention adopts the following technical scheme: in a first aspect, the invention provides a high-protein modified milk, wherein the raw materials for preparing the high-protein modified milk comprise raw cow milk, whey protein, polydextrose, soy protein, tremella powder and rice milk powder. The high protein modified milk is protein content of more than 6g in each 100mL products, and sources of protein in the products comprise soybean protein, raw cow milk, whey protein and the like. The invention aims to provide a preparation method of a high-protein modified milk for middle-aged and elderly people, which effectively solves the problems of insufficient protein intake and skeletal muscle loss of the middle-aged and elderly people by optimizing raw material formulas, particularly sources, proportions and dosages of proteins, has important roles in various aspects of human bodies, and has quality and function decline which are related to risks of various accidental injuries or diseases and are closely related to functions of strengthening skeletal and cerebral nerve health and the like of the middle-aged and elderly people. In addition, the prepared milk has the functions of improving intestinal health of middle-aged and elderly people, maintaining cognitive health, tonifying qi, tonifying blood and the like. The protein source of the invention adopts animal protein and plant protein to be compounded and matched. The animal protein comprises whey protein and casein in cow milk, wher
