Description

A kind of catfish fresh-keeping treating method
Technical field
The present invention relates to aquatic products Preservation Treatment technical field, and in particular to a kind of catfish fresh-keeping treating method.
Background technology
Catfish is common fresh-water fishes, and catfish delicious flavour, the few meat of thorn is more, and rich in the battalion such as protein, trace element Material is supported, is the splendid raw material as minced fish production, still, causes catfish meat easily rich in protein and fat in catfish It is oxidized, so that the flesh of fish produces bad smell, there is bilgy odour weight in surimi products production, the problem of freshness date is short, sternly Greatly developing for catfish culture industry and processing industry is affected again, so fresh-keeping guarantee the quality of catfish is a global problem, chitosan Have certain effect suppressing meat oxidation and antibacterial aspect, at present when fresh-keeping to catfish, smeared more using chitosan combine it is low Temperature preservation realization is fresh-keeping to catfish, but freshness date is not grown, and generally shorter than 7 days, also has act as protecting using nucleoprotamine at present Fresh dose of use, although nucleoprotamine biocidal property is obvious, cost of manufacture is higher, and yield is low, and then improves fresh-keeping cost, it is clear that Be not suitable for the fresh-keeping use of this cheap fingerling of catfish.
The content of the invention
The problem of fresh keeping time is short, and also or fresh-keeping cost is high be present to solve existing catfish preservation technology, it is of the invention Purpose is to provide a kind of catfish fresh-keeping treating method.
The technical solution adopted by the present invention is a kind of catfish fresh-keeping treating method, specifically:
When to catfish Preservation Treatment, fresh catfish, which is massacred, goes internal organ to clean up, after drying surface moisture, catfish surface with And inner homogeneous smears one layer of fresh-keeping liquid;
Specifically, the liquid based on bamboo fibre acidolysis thing of fresh-keeping liquid used in the present invention, Mucor fermentate, pure is added into basal liquid Spend the monoglyceride for 93-96%, modified potato starch obtains, specifically, adding the fermentation of 12-15mg Mucors in per L basal liquids Thing, 2-2.2g purity are 93-96% monoglyceride, 4-6g modified potato starch;
Specifically, by bamboo fibre be dipped in pH value be 3-3.5 light-coloured vinegar solution in, temperature be 45-50 DEG C, pressure 1.8-2MPa Lower heat-insulation pressure keeping handles 30-36 hours, filtration, is diluted to 50-60 times, based on liquid use;
Specifically, when Mucor fermentate makes, it is seeded to after Mucor is activated by 2-3 ‰ weight ratio by 30-50% wheat brans, 10- In the solid medium that 25% dregs of beans, 2-5% sucrose, 20-40% soluble proteins powder, 2-3% iron powders form, culture 96-100 is small When, 0-50 hours, beer regulation solid medium humidity is uniformly applied into culture medium in 75-78%, 51-80 hours, is led to Crossing wind mode reduces culture medium humidity to 60-62%;81-96 or 81-100 hours, 6-10 DEG C is cooled to, obtains Mucor Fermentate, after spray drying, make an addition in basal liquid;
Specifically, contain more than 90% VBT in Mucor fermentate;
Specifically, one layer of saturated brine regulation farina humidity is sprayed on farina top layer in 60-66%, in 550- 10-13 minutes are handled under 570MPa pressure, spray drying, obtain modified potato starch;
Specifically, modified potato starch after processing, forms cellular structures, 1 μm of its hole diameter <, aperture is covered with Whole starch particle surface, the volume in hole account for more than the 60% of particle volume.
Beneficial effect of the present invention is,
Catfish is after fresh-keeping treating method of the present invention processing, and under 3-5 DEG C of refrigerated condition, shelf life can extend to 35-38 My god, realize permanent effectively fresh-keeping purpose, and freshness date interior energy effectively removes catfish bilgy odour, improves the sense organ product of fresh-keeping catfish Matter;
Wherein, the present invention uses liquid based on bamboo fibre acidolysis thing, and bamboo fibre is dipped in the light-coloured vinegar solution that pH value is 3-3.5, Temperature is 45-50 DEG C, pressure is that heat-insulation pressure keeping handles 30-36 hours under 1.8-2MPa, resulting filtrate have it is stable into Film properties, it can ensure that various active ingredients are uniform in fresh-keeping liquid, are effectively adhered to catfish surface;
Wherein, the present invention adds Mucor fermentate in basal liquid, and actual Mucor fermentate is L- meat of the purity more than 90% Alkali, at present, VBT are the newly approved nutrition fortifiers in China, can promote the transport and oxidation of aliphatic acid, be generally used as Food additives use, but inventor stumbles on, and certain density VBT has preferable bacteriostasis, specific Dan Yin In sub- contrast test, the group for adding 12-15mg Mucor fermentates in every L basal liquids is applied to Nian compared to non-addition group Fish surface, under storage requirement of the present invention and in storage period, addition group catfish surface colony sum(TVC)Suppression is maintained at 3.35 below logcfu/g, rather than addition group, at the 7th day, catfish surface colony is total(TVC)Already exceed 25 logcfu/g;
In addition, during VBT is produced by Mucor fermentation, 2-3% iron powder is added into solid medium by the present invention, It is remarkably improved the purity of VBT, in single-factor contrast test, compared to non-addition group, the purity of VBT at least improves 44%;
In addition, the present invention 0-50 hours, beer is uniformly applied into culture medium during VBT is produced in Mucor fermentation Solid medium humidity is adjusted in 75-78%, mycelia fast-growth can be promoted;In single-factor contrast test, compared to applying water Group, during mycelial growth to equal height, the group for applying water has at least been used 92 hours, 51-80 hours, by wind side Formula reduces culture medium humidity to 60-62%;It can may prolong the generation phase of VBT, 81-96 or 81-100 hours, cool To 6-10 DEG C, to promote the final accumulation of VBT;
Wherein, the modified obtained farina of the present invention has fabulous adsorptivity, and storage period can have catfish bilgy odour Effect removes, and improves catfish organoleptic quality;
In addition, before to pressure treatment of the farina with 550-570MPa, one layer of saturation is sprayed on farina top layer Salt solution adjusts farina humidity in 60-66%, it is possible to increase finally gives the occupation rate of farina loose structure, i.e., The absorption property of modified potato starch is further improved, in single-factor contrast test, compared to the group of spraying water, potato The ratio that loose structure accounts for particle volume at least improves more than 33%.
