Abstract
The invention relates to a method for preparing grease-contained albumen powder by using protease to hydrolyze ictalurus punctatus head, and belongs to the technical field of comprehensive utilization of ictalurus punctatus head. The method uses enzymolysis of the ictalurus punctatus head to prepare the grease-contained albumen powder, a hydrolysate of the ictalurus punctatus head has basic nutrient components as same as the fish head, but because of the enzymolysis, the hydrolysate has unique flavor and is easily absorbed by human body, and hydrolysis liquid or dried products can be used for preparing food or health-care products, so the method is quite helpful for improving processing level of wastes of agricultural, animal and aquatic products, and generates greater economic effect.
Description
Technical field
A kind of protease hydrolysis channel catfishes head that utilizes is produced the method that contains the lipoprotein powder, belongs to channel catfishes head comprehensive utilization technique field.
Background technology
The channel catfishes head is one of main tankage in the channel catfish processing, and it is nutritious, and crude protein and crude fat content are respectively 25.3% and 20.47%.Simultaneously, the content of DHA in the channel catfishes head (22 carbon acid) and EPA (20 carbon 5 alkene acid) is all very high, and these two kinds of unsaturated fatty acidss are to vessel softening, blood fat reducing, brain tonic and delay senility beneficial.Simultaneously, also contain the material that is of value to human body just like taurine etc. in a large number in the channel catfishes head.From so so far, the fish head all by Chinese as keeping fit the good merchantable brand of brain tonic, and channel catfishes head nutrition horn of plenty more can become good food materials.
China is the big country of the breed and the processing of channel catfish, the flesh of fish is mainly used to outlet, and a large amount of fish heads is often discarded or be used as feed and process raw material and be sold to feed factory, and the fresh fish head amount that is used to eat of selling is smaller, can not satisfy the requirement of industrialization comprehensive utilization far away.Utilize enzymatic hydrolysis channel catfishes head, can be amino acid and the small peptide that is easy to absorb and have certain local flavor with the proteolysis of fish head, and the lipid acid of biologically active is retained in the hydrolyzed solution.Meanwhile, enzymolysis process can make fish-bone separate with other parts of fish head quickly, makes fish-bone can be used for other processing smoothly, as produces bone gelatin(e) or bone meal.
Channel catfishes head hydrolyzate has with the basic nutrition of the first sample of fish to be formed, but because enzymolysis makes it to have peculiar flavour, and easier be absorption of human body, its hydrolyzed solution or drying products can be used for the preparation of food or healthcare products.
Summary of the invention
The purpose of this invention is to provide a kind of protease hydrolysis channel catfishes head that utilizes and produce the method that contains the lipoprotein powder, utilize channel catfishes head enzymolysis to produce and contain the lipoprotein powder, level of processing for the tankage that improve China's farming, poultry, fishery products is very useful, and can produce very big economic benefit.
Technical scheme of the present invention: with channel catfishes head flush away blood stains and foreign material, cut out from center line then, place reactor, the built-in pH7-10 of reactor, 0.02mol/L phosphate buffered saline buffer, the feed liquid weight ratio is 1: 4～2: 1, is warming up to 30～50 ℃, adds Sumizyme MP, enzyme concentration is 500～1000U/g fish head, stir simultaneously, 30～50 ℃ of hydrolysis 100-150min of attemperation, hydrolysis finishes impurity such as back elimination fish-bone, concentrate and drying, promptly get product and contain the lipoprotein powder.
Beneficial effect of the present invention: the present invention utilizes channel catfishes head enzymolysis to produce protein powder, channel catfishes head hydrolyzate has with the basic nutrition of the first sample of fish to be formed, but because enzymolysis, make it to have peculiar flavour, and easier be absorption of human body, its hydrolyzed solution or drying products can be used for the preparation of food or healthcare products.
