Description

A kind of preparation method of the special sweet potato noodles of chafing dish
Technical field
The invention mainly relates to the preparation side of glass noodle processing technical field, more particularly to a kind of special sweet potato noodles of chafing dish Method.
Background technology
Sweet potato noodles, sweet potato sheet jelly, slip-knot and sweet potato vermicelli are the traditional cuisines of ancient Han nationality, primary raw material is scarlet Potato, with boiling not rotten long, delicate fragrance is tasty, food fado sample the characteristics of, be that the regional masses of most of China like and common food; Presently commercially available sweet potato noodles brand is various, and price is also uneven, and most of bean vermicelli not resistant to cook, and culinary art in short-term will lose Chewy mouthfeel is gone, and the bean vermicelli for being only seldom used exclusively for adding in the sweet potato noodles of chafing dish, chafing dish in the market leads to It is often that high temperature is stewed when long, accordingly, it would be desirable to bean vermicelli has a preferable suppleness, but some illegal businessmans are in order to increase bean vermicelli Boiling fastness, adds a large amount of additives, seriously endangers the healthy of consumer.
The content of the invention
In order to make up the defect of prior art, it is an object of the invention to provide a kind of preparation side of the special sweet potato noodles of chafing dish Method.
A kind of preparation method of the special sweet potato noodles of chafing dish, comprises the following steps:
(1)Sweet potato is crushed:Selection substance is 200 ~ 500g, fresh, complete sweet potato, cleans after soil, sweet potato is placed in totally In water, in 32 ~ 34kHz supersound washings 30 ~ 40 minutes, after taking-up, clear water was rinsed, and removes surface soil, it is ensured that bean vermicelli is without sand tooth Sense, is crushed to 60 ~ 80 mesh, obtains sweet potato paste;
(2)Soya bean is crushed:Soya bean is cleaned, is placed in the water of 3 ~ 4 times of amounts of soya bean weight and soaks 8 ~ 10 hours, be crushed to 40 ~ 60 Mesh, filtering obtains soya bean slurry;
(3)Soya bean is boiled:Yellow heating soybean milk is boiled 8 ~ 10 minutes, room temperature is naturally cooled to, surface grease is removed, must boil Soya-bean milk;
(4)Go out powder:Sweet potato paste is filtered, the water of potato slag weight equivalent is added into potato slag, in 30 ~ 35 points of 34 ~ 36kHz ultrasounds Clock, filtering, the ultrasound that adds water repeatedly 3 times merges all filtrates, 20 ~ 24 hours is stood in 8 ~ 10 DEG C, removes upper strata moisture, obtain wet Starch;
(5)Starch is dried:Soya-bean milk will be boiled to add in wet starch, be well mixed, be in -38 ~ -36 DEG C of freeze-drying to water content 3 ~ 5%, it is to avoid nutrition leak, increase the nutrient content of bean vermicelli, improve the boiling fastness of sweet potato noodles, it is to avoid traditional bean vermicelli is soft rotten viscous The shortcoming of pot, meets the dietary requirements of consumer, adds lactic acid bacteria, obtains dried starch;
(6)And powder:Add water, the weight of water is the 60 ~ 65% of dried starch weight, be well mixed into dried starch, it is quiet in 40 ~ 42 DEG C Put fermentation 5 ~ 7 hours, reduce powder ball pH, slightly sour agreeable to the taste, a large amount of small molecule nutritional ingredients of generation can increase powder ball suppleness, Sweet potato noodles is kept smooth chewiness after stewing, in 121 DEG C of thermophilic digestions 8 ~ 10 minutes, obtain ripe powder ball;
(7)Leak powder:Ripe powder ball is placed in vermicelli machine, leakage powder is carried out, a diameter of 3 ~ 4mm is placed in -32 ~ -30 DEG C of freezings 13 ~ 15 Hour, take out, obtain agar silk;
(8)Dry:It is that in 60 ~ 65 DEG C of drying room, drying to water content is 36 ~ 38% that agar silk is placed in into temperature, it is cooled to 40 ~ 45 DEG C, drying to water content is 24 ~ 26%, is 8 ~ 10% most after 32 ~ 34 DEG C of drying to water content, obtains dry bean vermicelli;
