[0009] Example 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 ma...

[0011] Example 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 mat...
