There are many raw materials used to process fish meal, such as whole fish, dead fish, live fish, shrimp and crab, fish innards, fish head and tail, etc. When reusing whole fish to process fish meal, users usually adopt different fish meal processing solutions, such as high-fat fish and low-fat fish, according to the fat content of the fish. We will share with you the fishmeal processing method of high-fat fish here.
The processing technology of high-fat fish meal is a process of defatting fish with higher fat content and then drying and flouring. First, heat the fish with a steamer or a dry hot air blower, so that the protein of the fish body tissue is thermally denatured and solidified, and the body fat is separated and dissolved. Then the solids are squeezed by a screw press, and then the solids are dried to make fish meal.
Drying methods are divided into dry hot air and steam methods. The temperature of dry hot air can vary from 100 to 400°C due to different heat sources; the steam method is indirect heating, and the drying speed is slow, but the quality of fish meal is good. The crude protein content of the whole fish after degreasing, de-soaking, drying, and crushing ranges from 50% to 60%.
The squeezed juice is acidified, spray-dried or heated and concentrated into fish paste. Fish paste can also be produced from fish viscera. The raw materials are hydrolyzed with enzymes, centrifuged, degreasing, and the hydrolysate is concentrated to make fish paste. The prepared fish paste can be sold directly in barrels, or can be sold with starch or bran as a carrier and then dried and crushed. The latter is called fish juice feed or mixed fish starch, and its nutritional value varies with the carrier.
