Abstract

A method for quickly brewing the low-salt squid soy sauce features that the by-product generated by processing squid is used as one of its raw materials, the endogenous proteinase is used for its hydrolyzing at 35-55 deg.C for 48-72 hr, and their soy leaven is used for its fermenting at 40-55 deg.C for 21-28 days and then at 30-38 deg.C for 7-12 days.

Description

A kind of speed of less salt petis is made production technology

Technical field

The present invention relates to a kind of flavouring, particularly relating to a kind of is the speed wine technology that raw material is produced the less salt petis with the squid processing byproduct.

Background technology

By traditional petis production technology, earlier with the raw material fish through thawing, cleaning, salted, fermentation, filtering, make liquid aquatic products flavouring through allotment again.The part by weight of raw material fish and salt is 1: 3, and at temperature 30-35 ℃ of condition bottom fermentation 9-18 month, the finished product color and luster was amber, and delicate flavour is dense.But because its fermentation period is long, the hold facility cycle is long, and investment is big, the product cost height; On the other hand, the petis salt content of making can not satisfy the demand of consumer to high-quality less salt petis up to 25-30g/100ml; Moreover traditional petis is the mixed culture fermentation of multiple microorganism, does not carry out strict control bacterium, makes the metabolite complexity, and some poisonous and harmful metabolites (as biogenic amines such as histamine) can impact consumer's safety; Because fermentation raw material and fermentation temperature all are fit to the spoilage organisms growth very much, can cause the fermentation failure of less salt petis again.At present, be used for being becoming tight raw material resources day of petis processing, and processing byproducts such as the fish head in the squid process, internal organ, skin account for greatly fish heavy about 1/3, contain rich in protein, have very high edible health and be worth, at present only as the source of partially protein in the feed.

Summary of the invention

The speed that the purpose of this invention is to provide a kind of less salt petis is made production technology, it can guarantee under the high-quality prerequisite of petis, make full use of the squid processing byproduct of low value, shorten the production cycle, reduce production costs, increase economic efficiency, constant product quality, goods rate height is easy to adopt automatic continuous production.

A kind of speed of less salt petis is made production technology, comprises raw material is thawed through flowing water that vacuum refrigeration is cut and mixed, hydrolysis, hydrolysate sterilization, koji, the system wine with dregs, fermentation is filtered, allotment, sterilization is characterized in that described hydrolysis is to utilize endogenous proteinase to be hydrolyzed, the water and the former slip weight ratio of adding are 0.4-2.0: 1, hydrolysis temperature is 35-55 ℃, and initial pH is 4.5-7.0, and hydrolysis time is 48-72 hour; Described system wine with dregs is that the hydrolyzate after the sterilization is placed the fermentation tank of sterilization, the saline solution and the former slip weight ratio of adding are 0.2-1.0: 1, the content of salt is 20-30g/100ml in this saline solution, and the soy sauce koji of interpolation and former slip weight ratio are 0.1-0.25: 1; Described earlier fermentation temperature is 40-55 ℃, and fermentation period is 21-28 days, and amino nitrogen content enters later stage fermentation when reaching 0.7-1.5g/100ml, and the later stage fermentation temperature is 30-38 ℃, and fermentation period is 7-12 days.

The present invention can guarantee under the high-quality prerequisite of petis, make full use of the squid processing byproduct of low value, increase the economic worth of squid processing byproduct, reduce of the pollution of squid processing byproduct to environment, shorten the production cycle, reduce production costs, increase economic efficiency, the product collection sauce perfume (or spice) of producing, ester perfume (or spice), bright perfume are one, and color and luster is reddish brown transparent, and every index has all reached the standard of unblemished fish soy sauce, constant product quality, goods rate height is easy to adopt automatic continuous production, and the product of production can satisfy the demand of market to high-quality less salt petis product.
