Description

Gel-like full-nutrition special medical food formula based on animal and plant double proteins and preparation method thereof
Technical Field
The invention belongs to the technical field of special medical foods, and particularly relates to a gel-like full-nutrition special medical food formula and a preparation method thereof.
Background
The special medical formula food is specially processed and prepared to meet the special requirements of people with limited eating, digestive absorption disorder, metabolic disorder or specific disease state on nutrients or diet, and comprises special medical infant formula food suitable for 0-12 months old and special medical formula food suitable for people over 1 year old. The formula food with special medical application can be used as a nutrition supplementing way to play a role in nutrition support. The formulation of special medical use food is mainly based on energy demand.
Double proteins refer to edible protein sources obtained from the nutritional dose-response relationship and precise interactions between vegetable and animal proteins, resulting in greater advantages than single proteins. A large number of researches show that the intake of double proteins can improve muscle level, make up for the deficiency of proteins and improve the nutrition and health of leukemia patients. Biproteins are rich in various amino acids and contain high levels of essential amino acids. The double-protein composite nutrition powder developed based on double proteins is rich in nutrition, easy to saturate and convenient to eat. In 2019, the development seminar of the "double-protein engineering" project is held in Beijing, and the seminar indicates that the foods prepared based on double proteins can effectively adjust the organism condition of the sick people and improve the physical health of the patients. The combined application of animal and plant proteins can effectively increase the quality of the proteins and improve the utilization rate of the proteins. The protein source of the current special medical use formula food is mainly milk protein of animal protein, and the special medical use protein module formula food based on animal and plant double proteins is presented.
By the end of 4 months in 2023, 108 special medical products are approved in China, special medical foods on the market are mainly divided into powder and emulsion, the domestic products mainly comprise the powder, about 80 percent of the products comprise 20 percent of the emulsion. The variety of domestic special medical food dosage forms is less. The powder has the advantages of convenient preservation, carrying and transportation, but has the disadvantages of uneven nutrients, etc. Compared with powder, the emulsion does not need rehydration operation, is simple to use, but has great development difficulty. Because the special medical food is mainly used for the nutrition support of clinical patients, the raw materials of the special medical food generally contain nutrients required by human bodies, including proteins, carbohydrates, grease, minerals, vitamins and the like. The oil-in-water (O/W) emulsion system prepared from the macro-nutrients and the micro-nutrients through the processes of mixing with water, homogenizing, sterilizing and the like is emulsion type special medical food. The special medical food in the form of milk is convenient to apply in the aspect of nutrition support without rehydration operation, and has good development prospect.
