Description
Technical field
The present invention relates to a kind of food-processing method, be specifically related to a kind of method of silkworm chrysalis being carried out to deodorization process.
Background technology
Silkworm chrysalis is the principal by product in silk spinning, silk reeling process.Be prepared into edible silkworm chrysalis and contain abundant nutrition, wherein, protein is 18 ~ 25%, containing 18 seed amino acids, wherein the necessary eight seed amino acid content of human body account for more than 40% of total amino acid, and component general equilibrium, meet FAO/WH0(FAO (Food and Agriculture Organization of the United Nation)/World Health Organization) the nutraceutical amino acid pattern of defined, this is rare in existing food; Silkworm chrysalis contains the unrighted acid of 3 ~ 4%, is one of necessary key element of growth in humans and metabolism, has and alleviate artery sclerosis, reduces the effect of the cholesterol in blood; In addition, silkworm chrysalis containing various trace elements and vitamins such as calcium, potassium, phosphorus, zinc, iron, selenium, is also a kind of desirable nutraceutical.
Have the custom of edible fresh aquatic food silkworm chrysalis in some places (such as the Northeast) of China, the price of some areas fresh aquatic food silkworm chrysalis has exceeded the price of cocoon shell.But, fresh aquatic food silkworm chrysalis there is peculiar smell and the shelf-life short.Peculiar smell due to silkworm chrysalis is in process, because protein breakdown in body causes, in prior art, for the deodorization process of silkworm chrysalis, is that silkworm chrysalis is first ground into powdery substantially, then processes.Such as, Chinese invention patent CN1142331A discloses a kind of deordoring process for silkworm chrysalis by microorgans, gets fresh silkworm chrysalis and pulverizes 40 mesh sieves, then carry out microorganism fungus kind fermentation, by zymotechnique deodorization, obtains dried silkworm chrysalis meal.Other such as active carbon adsorption and organic solvent infusion process etc. are also all process dried silkworm chrysalis meal.These methods, handling object is dried silkworm chrysalis meal on the one hand, can destroy nutrition largely in processing procedure, also causes mouthfeel to change simultaneously, does not meet traditional food custom; On the other hand, these process all can bring impact to product is edible, the microbial metabolic products such as, brought in microbial method is left over has certain peculiar smell, active carbon in active carbon adsorption is difficult to remove, organic solvent can cause secondary pollution etc., meanwhile, these methods also can only be used for dried silkworm chrysalis meal, and can not be used for fresh aquatic food silkworm chrysalis.
Owing to not having suitable fresh aquatic food silkworm chrysalis deodour method, all there is certain peculiar smell in current product, have impact on the mouthfeel of product; In addition, in order to extend the shelf life, can add Sodium Benzoate or sorbierite as anticorrisive agent, this does not meet the requirement of pollution-free food yet, and the shelf life of products of adding after anticorrisive agent is 4-6 month, still shorter.
Therefore, the deodorization processing method studying fresh aquatic food silkworm chrysalis is needed, to solve the above-mentioned problems in the prior art.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of preparation method of deodorization silkworm chrysalis, and to realize the deodorization process to fresh aquatic food silkworm chrysalis, acquisition mouthfeel is good, the deodorization silkworm chrysalis of long shelf-life.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of preparation method of deodorization silkworm chrysalis, comprises the following steps:
(1) fresh aquatic food silkworm chrysalis is cleaned, impregnation process;
(2) silkworm chrysalis after process is dry at 30 ~ 40 DEG C;
(3) adopt ozone generator to carry out deodorization process 2 ~ 3 hours to silkworm chrysalis, during process, by silkworm chrysalis monolayer alignment, ozone concentration is 400 ~ 800mg/m
3;
(4) with more than 50 degree white wine, the process of positive and negative spray is carried out to silkworm chrysalis, drain after completing;
(5) vacuum packaging radiation treatment, obtains deodorization silkworm chrysalis.
Further technical scheme, described step (1) comprises the following steps successively:
(1-1) by silkworm chrysalis tap water, drain;
(1-2) in bath raio be 1: 50 ~ 70 pure water in dipping 2 ~ 3 hours, in water, stirred silkworm chrysalis once every 25 ~ 35 minutes;
(1-3) silkworm chrysalis takes out, drains;
(1-4) step 1-2,1-3 is repeated once.
In technique scheme, in described step (1-2), in stainless steel pond, carry out impregnation process.
In technique scheme, in step (3), stirred once every 25 ~ 35 minutes to silkworm chrysalis, exchange positive and negative.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1, the present invention adopts ozone generator to process fresh aquatic food silkworm chrysalis, and through experimental verification, the silkworm chrysalis after process achieves deodorization, free from extraneous odour.
2, adopt white wine to spray in the present invention and coordinate irradiation sterilization to process, do not use anticorrisive agent, under vacuum packaging state, the shelf-life can reach 1 year, and avoid the conventional silkworm chrysalis peculiar smell adopting high-temperature sterilization method to cause increases simultaneously.
3, the present invention adopts the large bath raio impregnation process of pure water, and cooperation ozone treatment effectively can remove ash content, harmful substance and peculiar smell in product, ensures that product quality meets food standard.
4, the present invention adopts fresh aquatic food silkworm chrysalis as raw material, and does not carry out high-temperature process, and avoid the peculiar smell that high-temperature process causes, mouthfeel is good.
