Abstract

The invention belongs to the field of freeze-dried food processing and particularly relates to freeze-dried tremella soup and a preparation method thereof. Fresh tremella is chopped into 20-30 mm and placed in water to be precooked for 10-20 min, then rock sugar is placed, the tremella is heated on soft fire for 5-6 h, and stock is obtained; lotus root starch is placed in the stock, the mixture is evenly mixed and heated on big fire for 10 min, and concentrated soup is obtained; the concentrated soup is added to a mold and subjected to vacuum freeze-drying for 20-24 h after being quick-frozen for 15-20 h, metal detector packaging is performed, and the tremella soup is obtained. The finished product is rich in nutrition, long in shelf life, stable in nutrition ingredient and convenient to eat.

Description

A kind of freeze-drying dried tremella soup and preparation method thereof
Technical field
The invention belongs to frozen dried food manufacture field, be specifically related to a kind of freeze-drying dried tremella soup and preparation method thereof.
Background technology
White fungus is the good merchantable brand of nutritious tonifying, the tonic that righting is strong, also have develop immunitypty effect, existing white fungus product category and processing technology various, but usually product nutritional labeling is single, and processing cost is high, if add other nutriments, be easy to the cell tissue destroying white fungus, make polysaccharide coking in dried tremella extract, and then cause the color of dried tremella soup to deepen gradually; Further, the easy temperature influence of white fungus, especially, high temperature makes the space structure of collagen in white fungus change, and affects the absorption of human body to its nutritional labeling.
At present, white fungus product mostly is dried tremella soup and white fungus electuary on the market.Dried tremella soup is of high nutritive value, mouthfeel is good, but the shelf-life is short, mostly is namely to do and namely drinks; White fungus electuary long shelf-life, is generally dry powder, brew just edible, but nutrition leachable is low by adding water, and then causes the active ingredient of absorption of human body lower.
For this reason, dried tremella soup preparation technology combines with Vacuum Freezing & Drying Technology by the present inventor, on the one hand for solving the deficiency of existing portable type dried tremella soup product, on the other hand for improving the easy deliquescent behaviours of frozen dried food, a kind of instant being provided, being of high nutritive value, the thinking of the dried tremella soup of long shelf-life and preparation method thereof.
Summary of the invention
The object of the present invention is to provide dried tremella soup of a kind of high nutritive value, low cost of manufacture and preparation method thereof.
Be achieved especially by following scheme:
A kind of freeze-drying dried tremella soup, its raw material comprises: red date, weight part ratio that matrimony vine, weight part ratio that the bubble that weight part ratio accounts for 25% sends out white fungus, weight part ratio accounts for 20% rock sugar, weight part ratio account for 0.5% account for 0.5% account for the lotus root starch of 0.5 ~ 1%, and all the other are water.
Its preparation method, comprises the following steps:
(1) bubble is sent out white fungus chopping to 20-30mm, after putting it in water the 10 ~ 20min that precooks, put into rock sugar, with little fire heating 5 ~ 6h, obtain former soup;
(2) lotus root starch is put into after former soup stirs, heat 10min with big fire, obtain condensed soup;
(3) being added by condensed soup in mould after quick-frozen 15 ~ 20h, is 65 ~ 105 DEG C in temperature, and vacuum is through vacuum freeze drying 20-24h under 80 ~ 100Pa, and gold visits packaging, obtains dried tremella soup.
Described temperature of precooking is 80 ~ 100 DEG C.
Described little fiery temperature is 80 ~ 90 DEG C.
Described big fire temperature is 950 ~ 100 DEG C.
Described quick freezing temperature is≤-18 DEG C.
Described vacuum freeze drying temperature is 85 DEG C, and vacuum is 90Pa.
Beneficial effect of the present invention
The present invention adopts white fungus, rock sugar, lotus root starch to be that raw material makes dried tremella soup, by limiting material proportion and machined parameters control, makes storeroom generation cooperative effect.Dried tremella soup Middle nutrition composition of the present invention enriches, dried tremella soup prepared by the present invention program, under preservation a couple of days and different temperature process, carry out conventional nutraceutical composition detection, its result shows: Vitamin C content is about 90.2mg/100g, vitamin A content is about 125.3mg/100g, protein content is about 47.6%, further illustrates, and it is of value to the sound development of human body, for human body extra-nutrition element, and then be conducive to promoting body immunity.
