[0003] What is known so far is that tilapia fish scales are used as raw materials through lime soaking, acid hydrolysis or alkaline hydrolysis, or only tilapia fish skins are used as raw materials through hot water extraction, acid extraction, and alkaline extraction. , salt extraction and enzymatic extraction and other traditional methods, the products produced in this way have long production cycle, low yield, high production cost, low protein and amino acid content, and large molecular weight; in addition, tilapia is used The remaining tilapia skin has to be disposed of as a low-value item in the method of extracting collagen from fish scales. In order to overcome the disadvantages of the traditional production process, a production of fish collagen powder extracted from tilapia skin and fish scales is now invented. method

Embodiment 1

[0010] A production method for extracting fish collagen powder from tilapia fish skin and scales, which is characterized in that: fresh tilapia fish skin and scales are selected to remove impurities, washed, and then cleaned with purified water, using food grade The concentration of citric acid is 0.5%, soak for 2.5 hours, stir and stand still every half an hour, pour out the oil on the liquid surface, soak for 2.5 hours, rinse with pure water to neutrality, put the fish skin and scales into the plastic frame to drain , And then put the drained fish skin and scales evenly into the freeze-drying bin and quickly freeze to minus 40 degrees. Under vacuum, the frozen water molecules of the fish skin and scales are directly sublimated into water vapor, and then removed from the bin to dry The process takes about 10 hours. The dried fish skins and scales are pulled to the clean workshop, first coarsely pulverized and then ultra-finely pulverized to 120 meshes. The materials are weighed...

Embodiment 2

[0012] A production method for extracting fish collagen powder from tilapia fish skin and scales, which is characterized in that: fresh tilapia fish skin and scales are selected to remove impurities, washed, and then cleaned with purified water, using food grade The concentration of citric acid is 0.5% soak for 3 hours, stir and stand still every half an hour, pour off the grease on the liquid surface, soak for 3 hours, rinse with pure water to neutrality, put the fish skin and scales into the plastic frame to drain , And then put the drained fish skin and scales evenly into the freeze-drying bin and quickly freeze it to minus 35 degrees. In a vacuum state, the frozen water molecules of the fish skin and scales are directly sublimated into water vapor and removed from the bin for drying. The process takes about 10 hours. The dried fish skins and scales are pulled to the clean workshop, first coarsely crushed and then ultra-finely crushed to 100 meshes. The materials are weighed ...

Abstract

The invention belongs to a production method for extracting fish collagen protein powder from Tilapia mossambica skin and scale. The production method is characterized in that the fish collagen protein powder is pure fish collagen protein powder and is prepared by the following processes of: steeping the Tilapia mossambica skin and scale which serve as the raw materials in acid, freezing and drying, performing biological enzymolysis, filtering, spraying and drying, etc.; and the biological activity of the effective constituents is remained completely. The fish collagen protein powder subjected to the production extraction is high in content of extracted protein and amino acid and relatively low in content of fat, can meet the demand of human body to nutrient substances each day, is easily absorbed and utilized by the human body, and is helpful for improving the immunity of the organism of a human body, improving the memory, keeping the body healthy and energizing the body after long-term use. According to the production method, the leftovers of the Tilapia mossambica are fully utilized and prepared into the foods with nutrient substances, so that the enterprise benefit and the social benefit are obviously increased; and the production method is simple and convenient and is easily realized by technicians.

Description

[0001] Technical field [0002] The invention relates to a production method for extracting fish collagen powder from tilapia fish skin and scales. Background technique [0003] What we know so far is to use tilapia fish scales as raw materials through lime soaking, acid hydrolysis or alkaline hydrolysis, or only use tilapia fish skins as raw materials through hot water extraction, acid extraction, and alkaline extraction. , Salt extraction and enzymatic extraction and other traditional methods, so that the product produced has a long production cycle, low yield, high production cost, low protein and amino acid content, and large molecular weight; in addition, tilapia is used Fish scales are used as raw materials to extract collagen. The remaining tilapia skins have to be treated as low-value items. In order to overcome the shortcomings of the traditional production process, a production of tilapia skin and fish scales extracted fish collagen powder has been invented. method....
