Description
Technical field
The present invention relates to the siphonopods aquatic products of marine fishery, and siphonopods is removed particularly with regard to low temperature quality improver
The method of microorganism in aquatic products.
Background information
For siphonopods aquatic products (octopus, squid, inkfish) compared with terricole meat product, particularity is fairly obvious：1) it is high
Albumen low fat：Bone is few or nothing and the human body is relatively plump, for the human body rich in protein but obvious low in calories, fat content is low,
But rich in the highly important unrighted acid of health.2) trace metal ion for the multiple beneficial being rich in seawater
With a variety of nitrogenous micromolecular compounds of free nonprotein：Such as taurine and carnitine.3) internal and body surface carries a large amount of water
Microorganism in body.The special moral character of above-mentioned siphonopods aquatic products cause raw material be easy in general processing environment occur with
The problem of serious down：The albumen and unrighted acid being rich in are easily air oxidation so that deterioration in quality, or even go out
Now become sour rotten；Processing is not good at, and causes the loss of highly beneficial nutrition such as taurine；The microorganism carried by itself and processing
The harmful microorganism invaded in the poor environment of place is imbued with fast-growth, breeding thereon so that quality variation, severe patient even produce
Raw poisonous and harmful substance, greatly pathogenic risk is produced after eating.Therefore, want to produce the siphonopods aquatic products of high nutrition quality
Food, scientific and reasonable processing technology must be just used, the strong micro organism quantity reduced in raw material, just turns into abnormal important
Quality control method.
Traditional siphonopods processing of aquatic products is divided into dry process and pickling method.Shortcoming is also fairly obvious：Product appearance ugliness,
Taste as chewed wax, having no mouthfeel can say.Because process be it is open, it is special by high temperature or the oxidation of illumination
Nutriment unrighted acid oxidation deterioration, the undue dehydration of protein causes serious degenerative, free non-protein amino
Thiosulfonic acid etc. is largely lost in.Undoubtedly, this marine aquatic product processing mode has been fallen behind.
Chinese patent CN1973639A discloses a kind of method for removing siphonopods aquatic products epidermal mucus silt, including following
Step：(1) raw material thaws, and removes the internal organs, and cleans inner chamber and surface；(2) ice that the ratio between ice, water are 1: 1~3 is added in roller
Brine ice is made in water, the salt for adding 2%~8%, and clean octopus is put into roller, and octopus, weight saline ratio be 1~
3: 1,10~45min of tumbling, bleed off salt solution；(3) standby same frozen water, 0.2%~0.8% alum is added, after dissolving, is poured into
Roller, 5~30min is rotated, bleeds off alum water.(4) octopus is taken out, surface is rinsed with clear water.This method is safe and non-toxic, simple real
With being widely portable to the processing of all kinds of siphonopods products.
