Description

A kind of preparation method of silkworm chrysalis food and silkworm chrysalis food and application
Technical field
The invention belongs to silkworm chrysalis food technical field, be specifically related to a kind of preparation method and silkworm chrysalis food and application of silkworm chrysalis food.
Background technology
China is sericulture big country, and silkworm chrysalis resource is very abundant.The edible historical origin of silkworm chrysalis for a long time, is among the peoplely regarded as silkworm chrysalis product on nutritious tonifying always.Modern nutriology result of study shows, fresh silkworm chrysalis is rich in the nutrients such as albumen, fat, vitamin and mineral element, its crude protein content is up to 14%-15%, and be the adequate proteins that contains 18 seed amino acids, essential amino acid harmony is good, ratio is suitable mutually, be easily absorbed by the body, and be a kind of high-quality protein resource that has more nutritive value than pork, mutton, egg, milk.In addition, the unsaturated fatty acid content of tool plurality of health care functions high (account for amount of total fat 72%) in silkworm chrysalis fat, wherein oleic acid 33%, leukotrienes 31%, linoleic acid 8%, in addition containing function factors such as cupreol, alpha-tocopherol and lecithin.Therefore, this healthy food that has nutritive value and medical value of silkworm chrysalis is subject to consumer's favor day by day.
At present, silkworm chrysalis is unique insects food in health ministry approval " as the new resource for food list of bread and cheese management ", but its edible way is also confined to the traditional mode that marketing fresh is eaten raw, business-like food or intermediate raw material are still rare on market, and this is mainly because silkworm chrysalis exists following technical bottleneck problem in process: in (1) dry run, easily collapse-deformation causes outward appearance not good; (2) chitin shell causes flavoring to be difficult for infiltration, and the difficult evaporation of silkworm chrysalis internal moisture simultaneously causes energy consumption larger; (3) long-time high-temperature process easily causes nutritional labeling oxidation and causes local flavor not good.Therefore, by improve the techniques such as dry, excipient in silkworm chrysalis food process and seasoning obtain a kind of operate simple and easy, energy consumption is low and can keep the processing method of silkworm chrysalis profile and local flavor, is the direction of current silkworm chrysalis food development.
Summary of the invention
First object of the present invention is to provide a kind of preparation method of silkworm chrysalis food, and this preparation method is simple to operate, and energy consumption is low.
The present invention also aims to provide the silkworm chrysalis food obtaining by the preparation method of above-mentioned silkworm chrysalis food, this silkworm chrysalis food nutrition, outward appearance and raciness.
Last object of the present invention is to provide above-mentioned silkworm chrysalis food in the application of preparing in fried and tinned food, silkworm chrysalis food in the present invention, can be used as a kind of ready-to-eat food and come into the market, also can be used as a kind of intermediate raw material, make fried and tinned food etc.
First object of the present invention is achieved by the following technical measures: a kind of preparation method of silkworm chrysalis food, contains following steps:
(1) prepare half-dry type silkworm chrysalis
Select fresh silkworm chrysalis, after pretreatment, be dried processing;
(2) preparation mixes seasoning gel
Choosing agar, carragheen and white fungus Ultramicro-powder mixes, make premix rubber powder, in premix rubber powder, add sucrose water and salt to mix and make ternary premixing glue, in ternary premixing glue, add mushroom water extract, pork cream and rosemary oil, through homogeneous processing, make and mix seasoning gel;
(3) pretreatment of half-dry type silkworm chrysalis
On half-dry type silkworm chrysalis surface, pricking hole processes;
(4) excipient and seasoning
To be immersed in the mixing seasoning gel that step (2) makes through pricking the half-dry type silkworm chrysalis processed of hole, adjusting temperature is 80 ℃ ~ 90 ℃, and vacuum is 0.03 ~ 0.05MPa, carries out excipient and seasoning processing;
(5) post processing
To, through the silkworm chrysalis of step (4) excipient and seasoning processing through post processing, make silkworm chrysalis food.
The inventive method substitutes the traditional raw materials such as starch, dextrin and synthetic tasty agents with the functional raw material agar, carragheen, white fungus Ultramicro-powder, mushroom water extract and the pork cream that come from natural plants, marine alga and animal, gives product better functional.
Pretreatment described in step in the present invention (1) comprise choose cocoon after the fresh silkworm chrysalis of 4 ~ 7 days, reject disease pupa and dead pupa, fresh silkworm chrysalis low temperature is preserved to prevent that silkworm chrysalis is further developed to the adult stage.Temperature when wherein low temperature is preserved is preferably 0 ~ 4 ℃, take 4 ℃ as good.
When dry in step of the present invention (1), baking temperature is preferably 50 ℃ ~ 60 ℃, be dried to moisture in silkworm chrysalis and be 50% ~ 60% when preventing that follow-up bundle hole from processing the exosmosing of silkworm chrysalis juice; Wherein drying equipment is preferably heat pump drier.
