Abstract

The present invention relates to the technical filed of fish meal and particularly relates to a preparation method of steam fish meal and the prepared steam fish meal. The preparation method consists of the following steps: A. raw materials are selected, the selected raw materials are washed, and the washed raw materials are smashed; B. the smashed raw materials are subjected to a cooking treatment; C, the cooked raw materials are subjected to a squeezing treatment to obtain squeezed cakes and squeezed liquid; the squeezed cakes are subjected to a shredding treatment; and the squeezed liquid is treated to obtain coarse residues, coarse fish oil and juice water, the juice water is concentrated, the concentrated juice water and the coarse residues are added into the squeezed cakes, and the mixture is subjected to a steam drying; and D, the mixture is cooled, and the cooled mixture is subjected to a crushing treatment to prepare the steam fish meal. The preparation method is simple in technology, stable in quality, and less in nutrient loss, slows down the lipid oxidation process of the fish meal and reduces the effects of environment caused by excrement. The steam fish meal is good in quality, high in nutritional value, high in protein contents, has main amino acids basically the same with the in vivo tissue amino acids of chickens, fish, shrimps and other aquaculture animals, is rich in mineral contents, can promote the growth and development of cultured animals, and improves the nutrient content of the cultured animals.

Description

technical field [0001] The invention relates to the technical field of fish meal, in particular to a method for preparing steamed fish meal and the prepared steamed fish meal. Background technique [0002] Fish meal is a high-protein feed raw material that is made of one or more kinds of fish, after degreasing, dehydration, and crushing. Fish meal does not contain cellulose and other difficult-to-digest substances. It has high crude fat content and is rich in vitamins and minerals. and growth factors, which play an extremely important role in industries such as feed. [0003] The quality of fishmeal is greatly influenced by raw material selection and processing methods. In the current production of fishmeal, there are often the following defects: the loss of nutrients in fishmeal is serious, resulting in serious waste of materials, and it also leads to a large amount of pollutant discharge in the process of fishmeal processing, which seriously pollutes the environment. In ...
