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 a

Embodiment 1

[0101] A method for preparing dietary food using fish as raw material, comprising the steps of:

[0102] S1, raw material screening: take the fish meat of perch;

[0103] S2, ripening: place the fish described in step S1 at 100°C and heat for 15 minutes to obtain cooked fish;

[0104] S3, pre-crushing: add water to the cooked fish meat described in step S3, and use a colloid mill to crush it into a paste. The treatment particle size of the colloid mill is 2 μm; wherein, the weight ratio of the cooked fish meat to water is 1:1;

[0105] S4. Hydroxyproline content monitoring: Add the pretreated gelatin solution to the paste described in step S3 to obtain a slurry, so that the hydroxyproline content in the slurry is 300-400 μg / g, and the total gelatin content is the required 3 ± 1% of the slurry weight, the assay method of the hydroxyproline content is operated according to GB / T 9695.23-2008 (meat and meat products-hydroxyproline content determination); the preparation of the pr...

Embodiment 2

[0111] A method for preparing dietary food using fish as raw material, comprising the steps of:

[0112] S1, raw material screening: take the fish bones, fish skin, fish scales and fish meat of grass carp;

[0113] S2, ripening: place the fish described in step S1 at 100°C and heat for 20 minutes to obtain cooked fish;

[0114] S3. Pre-crushing: add water to the cooked fish described in step S3, and use a colloid mill to crush it into a paste. The treatment particle size of the colloid mill is 1 μm; wherein, the weight ratio of the cooked fish to water is 1:1;

[0115] S4. Hydroxyproline content monitoring: Add the pretreated gelatin solution to the paste described in step S3 to obtain a slurry, so that the hydroxyproline content in the slurry is 400-500 μg / g, and the hydroxyproline content in the slurry is The total gelatin content is 4 ± 1% of the slurry weight, and the determination method of the hydroxyproline content is operated according to GB / T 9695.23-2008 (meat and m...

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...
