Abstract

The present invention relates to the technical field of sweet potato vermicelli and particularly relates to a processing method of raw pulp sweet potato vermicelli. Sweet potato pulping, low temperature moisture content adjusting, edible salt adding, vacuum low temperature putting still, moisture content reducing, high speed stirring, tableting and air-spreading to cool, and shredding are carried out to prepare the sweet potato vermicelli. The nutritional components of the sweet potatoes are not destroyed and the nutrient loss of the sweet potatoes is avoided. Besides, the prepared sweet potato vermicelli is both excellent in toughness and smoothness. In the cooking process, soup burnt phenomenon is not easy to happen, and the quality of the raw pulp sweet potato vermicelli is improved. By the high-speed stirring method, the sweet potato raw pulp is subjected to a certain temperature increasing and curing during the process, so that the mouthfeel of the prepared sweet potato vermicelli is improved.

Description

A kind of raw slurry sweet potato vermicelli processing method
Technical field
The present invention relates to sweet potato vermicelli technical field, especially a kind of raw slurry sweet potato vermicelli processing side Method.
Background technology
Sweet potato vermicelli processing technique is first producing starch, then at processing bean noodles.This bean noodles Shortcoming is that bean noodles nutrition is single, because by other battalion in Radix Ipomoeae during producing starch Form and point weed out completely;Being exactly that technical process is long a shortcoming, cost is high.Therefore, Study a kind of method that will directly process bean noodles after new fresh sweet potatoes slurrying, solution is presently required Technical problem.
In consideration of it, prior art occurs in that and substantial amounts of prepares sweet potato vermicelli about Radix Ipomoeae oleo stock Method, such as the producer disclosing a kind of vermicelli with sweet potato puree of Patent No. 201110357022.X Method, comprises the following steps: 1. select without rotting, without the new fresh sweet potatoes of black speck, 2. will select Fresh sweet potato washing is clean, 3. the Radix Ipomoeae cleaned up is made the starch by 120 eye mesh screens Breast, 4. adds the α-amylase of 300~400ppm in starch milk, 5. will add amylase Starch milk be placed in the double-countercurrent evaporation device of vacuum-0.096Mpa, temperature 50 C, concentrate To the potato slurry that Baume degrees is about 30, the most again potato slurry is placed on conveyer belt formation 1.1~1.2mm Pulp layer, 7. will through gas steam formed bean sheet jelly predry 4~5min at a temperature of 80~90 DEG C, 8. by the bean sheet jelly aging 2~3h through predry, 9. by the bean sheet jelly cutting after aging, 10. finally will cut Good bean noodles dry 8h at a temperature of 35~55 DEG C.The bean noodles produced are the most glittering and translucent, chewy Softness, remains again the natural juice of Radix Ipomoeae, original flavor, former perfume (or spice).
Based on this, this researcher on the basis of existing technology, in conjunction with the nutrition to sweet potato vermicelli The improvement of the improvement of structure and mouthfeel etc. carries out research and discovery, and then uses Radix Ipomoeae raw slurry system Standby raw slurry sweet potato powder, and combine the adjustment of step of preparation process, parameter so that the Radix Ipomoeae of preparation The comprehensive nutrition of bean noodles, loses relatively low, and mouthfeel is pliable and tough, smooth, prepares for sweet potato vermicelli Field brings a kind of new approaches.
Summary of the invention
In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of raw slurry Sweet potato vermicelli processing method.
It is achieved particular by techniques below scheme:
A kind of raw slurry sweet potato vermicelli processing method, comprises the following steps:
1) after Radix Ipomoeae being peeled, it is placed in fiberizer, grinds pulping;
2) by step 1) in slurry be placed in the environment that temperature is 15-25 DEG C and process to moisture content It is 35-60% by quality ratio;
3) to step 2) slurry that obtains adds account for slurry by percentage to the quality for the Sal of 2-5%;
4) by step 3) in the serosity that processed to be placed in vacuum be under 0.02-0.08MPa, Temperature is static placement 1-3h at being 3-8 DEG C;
5) by step 4) moisture in mass is adjusted to 15-20% in the slurry that processed After, it is sent in blender, using mixing speed is 1000-8000r/min stir process After 20-30min, tabletting, airing, shredding, it is thus achieved that raw slurry sweet potato vermicelli.
Described Radix Ipomoeae, it is after peeling, and uses starch solution immersion treatment 10-40min.
Described starch solution, its be use starch and water according to mass ratio be 1: 3~7 mix after, After it is processed 1-3min in the environment that temperature is 35-47 DEG C, by it in vacuum it is Place 20-30min under 0.02-0.08MPa, and use ultrasonic Treatment 3-7min, it is thus achieved that.
Described ultrasound wave, its frequency is 20-50Hz.
Described starch solution, starch therein uses corn starch, wheaten starch, big At least one in rice starch.
Described step, is additionally included in the freezing after shredding and defrosting processes step.
Described freezing, its temperature is to carry out freezing processing 10-30min-20~-1 DEG C.
Described defrosting, is that at 10-20s, the temperature in freezing stage is warming up to 50-70 DEG C.
Described step, it also includes sterilization process steps after shredding.
Described sterilization process steps is that the material after shredding step being completed is in vapor (steam) temperature Sterilization treatment 1-3s at 80-120 DEG C, or used ultraviolet treatment with irradiation 1-3s.
Compared with prior art, the technique effect of the present invention is embodied in:
By Radix Ipomoeae is pulled an oar, low temperature adjust moisture, add Sal, vacuum and low temperature static, Reducing moisture, high-speed stirred, tabletting airing, shredding are prepared as sweet potato vermicelli so that red Nutritional labeling in potato is not exposed to destroy, it is to avoid the loss of Radix Ipomoeae Middle nutrition composition;And Make the toughness of sweet potato vermicelli of preparation, smooth degree the most excellent, and during cooking, its It is not susceptible to stick with paste soup phenomenon, improves the quality of raw slurry sweet potato noodles;And pass through high-speed stirred Mode so that the raw slurry of Radix Ipomoeae in the process, obtains certain intensification, ripening so that its system The mouthfeel of standby one-tenth sweet potato vermicelli is improved.
The present invention is a major advantage that and can guarantee that sweet potato vermicelli nutritional labeling is scattered and disappeared less Under premise, improve the toughness of sweet potato vermicelli, mouthfeel, reduce the strip-breaking rate during cooking, carry The quality of high sweet potato vermicelli;And shorten sweet potato vermicelli processing process, it is to avoid heating Energy consumption during hyperthermic treatment, reduces the production cost of sweet potato vermicelli.
The operating procedure of the present invention is simple, it is easy to operation, it is possible to realize industrialization.
In addition, this researcher, also after Radix Ipomoeae is peeled, uses starch solution to soak so that Sweet potato starch acts on the composition in starch solution, improves the quality of Radix Ipomoeae, improves Radix Ipomoeae The ratio of briquetting of sweet potato vermicelli prepared by slurry, reduces the oxygenation efficiency of starch, improves the quality of sweet potato starch.
Through the freezing and process of defrosting step so that the sharp and clear degree of sweet potato vermicelli is changed Kind.And the shelf-life of the sweet potato vermicelli of the present invention is longer, it is to avoid tradition boil sweet potato paste, The nutritional labeling that sweet potato starch etc. cause wrecks, and prepares sweet potato vermicelli by raw slurry, It is made to compare the extended shelf-life of sweet potato vermicelli prepared by traditional sweet potato vermicelli preparation technology Time of 1/3rd.
Contrast test in the shelf-life herein is mainly after producing formation product, is deposited into Under identical environmental condition, and the change to nutritional labeling therein, color and luster changes, pliable and tough, The change etc. of smooth degree is observed and is detected, and contrasts the shortest cycle of its These parameters change Add up and draw.
