Embodiment 1

[0018] Take the leftover waste after processing fresh bay scallops, wash them with 3% salt water, drain the water, mash them into minced meat with a chopping machine, mix the minced meat with water at a ratio of 1:4, and grind them into a homogenous slurry with a colloid mill. Ultrasonic treatment for 0.5h, power 300W; adjust pH to 7.0, add 0.5% enzyme activity 5×10 5 U / g Bacillus subtilis neutral protease and 0.5% enzyme activity 3.9×10 5 U / g of papain, stirring and enzymolysis at 55°C for 4 hours, passing through a 200-mesh filter, high-temperature instantaneous sterilization and enzyme sterilization, distillation and concentration to the original volume at a temperature of 50°C and a pressure of 0.1MPa 1 / 3 of the scallop was spray-dried, the air inlet temperature was set at 105°C, and the outlet air temperature was 85°C, and then packaged and sealed at a relative humidity of 40% to obtain light yellow scallop hydrolyzed protein powder.

Embodiment 2

[0020] Take fresh or frozen scallop processing scraps, wash them with 1% salt water, drain the water, grind them into minced meat with a chopping machine, mix the minced meat with water at a ratio of 1:1, and then grind them into a uniform shape with a colloid mill. slurry; the homogenate was ultrasonically treated for 0.2h with a power of 400W; the pH was adjusted to 7.5, and 2% enzyme activity 5×10 5 U / g of Bacillus subtilis neutral protease, the temperature is 45 °C and the enzymolysis is 6 hours; it is filtered through a tubular pressurized filter with a 200-mesh sieve; it is sterilized by high temperature instantaneously; it is concentrated by vacuum distillation at a temperature of 50 °C. Concentrate to 1 / 4 of the original volume at a pressure of 0.1MPa; use spray drying, set the inlet air temperature at about 105°C, and the outlet air temperature at about 85°C; pack and seal at a relative humidity of 40%, and obtain a light yellow color Scallop Hydrolyzed Protein Powder...

Embodiment 3

[0022] Take fresh or frozen scallop processing scraps, wash them with 2% salt water, drain the water, grind them into minced meat with a chopping machine, mix the minced meat with water at a ratio of 1:3, and grind them into a uniform shape with a colloid mill slurry; the homogenate was ultrasonically treated for 1 hour with a power of 200W; the pH was adjusted to 6, and 0.5% enzyme activity 5×10 5 U / g Bacillus subtilis neutral protease and 1% enzyme activity 5.7×10 5 U / g of trypsin, stirring and enzymolysis at 60°C for 4.5h; filtering through a 200-mesh sieve of a tubular pressurized filter; high temperature instantaneous sterilization; concentration: concentrated by vacuum distillation at a temperature of 50°C, Concentrate to 1 / 2 of the original volume under the condition of 0.1MPa; use spray drying, set the inlet air temperature at about 105°C, the outlet air temperature at about 85°C, and pack and seal at a relative humidity of 50%, to obtain light yellow Scallop Hydrolyz...

Abstract

The invention relates to a method for preparing scallop hydrolyzed protein powder, in particular to a method for preparing scallop hydrolyzed protein powder by using scallop scrap wastes, which belongs to the field of resource environment. The method uses the fresh or frozen scallop scrap wastes as a raw material and comprises the following steps: firstly, washing the raw material after the scallop scrap waste are washed or unfrozen, mashing into meat paste by a chopper mixer; secondly, grinding the mashed raw material into colloid homogenate by a colloid mill, and processing the homogenate by the ultrasonic waves; and thirdly, adding an exogenous enzyme to be conducted for enzymolysis, filtrating, sterilizing, condensing and drying a hydrolysate to obtain the scallop hydrolyzed protein powder. With the adoption of the ultrasonic waves, the lysate and endoenzyme can be effectively promoted to be released, and the use ratio of the exogenous enzyme can be improved; furthermore, the product has trophism and functionality; and meanwhile, the protein powder is fresh in taste, high in contents of protein and amino nitrogen and implements green and environmental protection, so that the protein powder can be served as an ingredient of the condiments including seafood soy sauce and seafood seasoning packet, and can be served as the raw material for health food and medicine deep processing.

Description

technical field [0001] The invention relates to a method for preparing scallop hydrolyzed protein powder, in particular to a method for preparing scallop hydrolyzed protein powder by using scallop scraps, which belongs to the field of resources and environment. Background technique [0002] Scallops mainly include Hawaiian scallops, bay scallops, and branch-hole scallops. Because they are rich in protein and a variety of flavor substances, they are extremely delicious and are very popular among people. With the continuous expansion of the scale of scallop farming, the output has increased steadily. At present, scallop products are mostly processed into frozen scallops except for fresh ones in coastal areas, and there are also a small amount of dried scallops. Scallop products are limited to scallop meat products, and scallop scraps such as scallop shells are discarded as domestic garbage. Scallop scraps are rich in protein, and its development and utilization have not ...
