Production method of diet food with fishes as raw material

Abstract

The invention discloses a production method of diet food with fishes as a raw material. The production method of the diet food with the fishes as the raw material comprises the following steps: addingwater into cooked fish, and crushing an obtained mixture by means of a colloid mill with processing granularity of 1-9 [mu]m into a paste; adding a pre-processed gelatin solution into the paste to obtain pulp, so as to make the content of hydroxyproline in the pulp equal to 200-500 [mu]g / g and to make the total content of gelatin in the pulp account for 2%-5% of the weight of the pulp; homogenizing the pulp to obtain cream, so as to make the particle size of the cream equal to 100-5000 nm and to make the average particle size equal to 100-3000 nm; and conducting filling and sterilizing on thecream to obtain the diet food. By means of the production method of the diet food with the fishes as the raw material, the fish with a rough taste is refined into micron-sized or even nano-sized particles, and a product with layered solid and liquid is processed to achieve an even stale state; and texture properties of a solid meat product are changed so that people with poor swallowing functionscan fully take in food, and accordingly the risk of malnutrition caused by choking is avoided.

Description

technical field [0001] The invention relates to the technical field of food processing, and more specifically, relates to a method for preparing dietary food using fish as raw materials. Background technique [0002] my country is a major producer of aquatic food in the world. According to statistics from the 2019 China Fishery Statistical Yearbook, from November 1, 2017 to October 31, 2018, the total output value of the fishery economy of the whole society in my country was 2,586.447 billion yuan, and the total output of aquatic products reached 64.5766 million tons, including 33.0143 million tons of marine products and 34.5623 million tons of freshwater products, accounting for 51.1% and 48.9% of the total output respectively; 53.97% and 58.86%, it can be seen that fish processing plays an increasingly important role in ensuring the supply of aquatic products in our country. At present, the processed fish products in my country are mainly surimi products, dry-cured products...

Problems solved by technology

Due to the high water content of freshwater fish meat, the cathepsin in the body is very active at room temperature, and the fish meat is easy to be corrupted. After freezing and thawing, it is easy to separate the water and meat. Therefore, there are few processed freshwater fish products on the market.

Moreover, due to the logarithmic freshwater fish having many intermuscular spines, it is not easy to process, and the types of deep-processed freshwater fish products are poor and the output is scarce.

[0004] At present, the food sold in the Chinese market for people with dysphagia is mainly coagulated powder based on thickeners. Consumers need to add it to liquid food by themselves, such as milk, soup and other foods. It is difficult for consumers to accurately control the amount of coagulated powder added, and patients Nutrient sources are limited to liquid food, which can easily lead to unbalanced nutritional intake and affect the health of patients
