[0002] At present, fishmeal plays an extremely important role in feed and other industries, and its usage is huge. Therefore, in order to meet the market demand for fishmeal, fishmeal is mainly prepared by directly processing fresh fish. However, it is found in actual production that due to fresh fish The water, oil, and large-chain protein molecules in the body are extremely high, so it is easy to cause the deterioration of fish meal and other phenomena, and it is also not conducive to the absorption of nutrients in fish meal. Therefore, in the current production of fish meal, extrusion, steaming, etc. are often used. Exclude the water, oil and protein in the fresh fish, and then prepare the fishmeal. On the one hand, this method leads to a serious loss of nutrients in the fishmeal, resulting in a decrease in the nutrition of the fishmeal, and a serious waste of materials. It also leads to fishmeal processing. The discharge of pollutants in the process is large, which seriously pollutes the environment. On the other hand, the absorption and utilization rate of protein contained in fishmeal is still relatively low, which is not conducive to absorption, which seriously affects the production and use of fishmeal. Therefore, in view of this situation, There is an urgent need to develop a new fishmeal preparation process to meet the needs of practical use

Embodiment 1

[0019] Such as figure 1 A kind of fish meal preparation method with high protein utilization rate shown, comprises the steps:

[0020] The first step is concentrated fermentation. The raw fish used to prepare fish meal is stored in a centralized manner, and the fermentation bacteria liquid is evenly sprayed on the raw fish, and then the external environment temperature of the raw fish is kept constant and fermented in an environment of 36°C for 10 hours. During the fermentation process, another The liquid produced by fermentation is collected, wherein the weight of the fermentation liquid is 3% of the weight of the raw fish;

[0021] The second step is drying and crushing. Mix the fermented raw fish with the liquid produced by fermentation, and then use drying equipment to dry. After drying, the water content of the raw fish is 20%, and then the dried raw fish Pulverize and prepare fish block particles with a length of 1 cm;

[0022] The third step is to decompose, then add ...

Embodiment 2

[0027] Such as figure 1 A kind of fish meal preparation method with high protein utilization rate shown, comprises the steps:

[0028] The first step is concentrated fermentation. The raw fish used to prepare fish meal is stored in a centralized manner, and the fermentation liquid is evenly sprayed on the raw fish, and then the external environment temperature of the raw fish is kept constant and fermented in an environment of 40°C for 20 hours. During the fermentation process, another Collect the liquid produced by fermentation, wherein the weight of the fermentation liquid is 1% of the weight of the raw fish;

[0029] The second step is drying and crushing. Mix the fermented raw fish with the liquid produced by fermentation, and then use drying equipment to dry. After drying, the water content of the raw fish is 10%, and then the dried raw fish Pulverize and prepare fish block particles with a length of 0.5 cm;

[0030] The third step is to decompose, then add pepsin solut...

Abstract

The present invention provides a preparation method for fish meal with high protein utilization. The preparation method comprises steps of centralized fermentation, drying and crushing, decomposition process, cooking, drying and crushing, puffing and the like. The preparation method has characteristics of simple process, high source material utilization and less waste pollutants, and effectively overcomes the defect that during the traditional process of preparing fish meal from fresh fishes, a fish oil-protein separation step is needed, so that on the one hand, protein content in the fish meal is effectively increased, and the material loss and waste discharge amount in fish meal processing are reduced, on the other hand, large protein chains are effectively degraded, thereby improving the absorption and utilization of proteins. So that processing costs of the fish meal are reduced, and content and absorption rate of nutrients in the fish meal are increased.
