Description
Technical field
The invention belongs to food processing technology field, especially belong to the prescription and the processing technique field thereof of noodles with fresh sweet potato.
Background technology
Sweet potato is a kind of coarse food grain that is rich in the multiple nutrients composition.It is compared with wheat, rice, corn, Chinese sorghum, and its protein, sugar, cellulose, inorganic salts, calcium, carrotene, thiamine, riboflavin, ascorbic acid, anthocyanidin rank first, and contains rich in amino acid.The necessary amino acid of human body particularly, than wheat, rice height, sweet potato also is rich in mucus protein, can keep the lubrication in the articular cavity, keep the elasticity of human body painstaking effort tube wall, stop atherosclerotic, reduce subcutaneous fat, prevent adesmosis in the liver kidney, improve body immunity, thereby have significant antimutagenic effect and tangible effect for reducing blood fat.Nineteen ninety-five U.S. biologist finds that sweet potato contains dehydrobenzene (DEHA), can be used for preventing colon cancer and breast cancer; Japanese state-run illness Prevention Research institute in 1996, selecting 20 kinds has the vegetables of remarkable depression effect to cancer, wherein, first is ripe sweet potato (98.7%), second sweet potato of making a living (94.7%), asparagus ranked third position (93.7%), more than shallot (16.3%), garlic (15.9%) by force; In addition, sweet potato still is a kind of physiological alkalinity food, can regulate the human acid-base balance, and therefore, sweet potato is a kind of comparatively desirable health food.
Konjaku is by the rehabilitation class dietotherapy articles for use of the traditional Chinese medical science as diabetes and high fat of blood; Konjaku powder is used in the food processings such as jelly, dessert, the smooth preferably swelling effect of tool.Konjaku powder has strong water imbibition, and the concentration as 0.50% just can form thicker thick mucus, but only remains just can demonstrate its stronger adhesion strength after its abundant slowly suction.Therefore, must be according to the characteristics requirement of different food products, the konjaku powder of selecting different size is as auxiliary material, and the effect of selecting for use process matched therewith just can obtain.
Vermicelli are one of staple foods of China people, and the enhancing along with growth in the living standard and health of people consciousness in recent years, more and more is subjected to people's welcome as functional form, health vermicelli such as egg noodle, jet rice vermicelli, kelp vermicelli, fine-dried vegetable noodles.Wherein, also have with sweet potato (application number: 921029187,03135115.8) or konjaku (200510020832.0) be the vermicelli that raw material is made; In addition, the nineties in last century, once there was report to do cladding (95 years people such as Chinese sweet potato Feng Ji) with sweet potato whole powder.But they or adopt sweet potato starch, or adopt sweet potato whole powder to make vermicelli, and directly be not processed into vermicelli with fresh sweet potato, can make bright nutrient sweet potato ingredients from lossing like this, reduce its nutritive value.This main cause is to be rich in polyphenolic substance in the fresh sweet potato, under the normal condition, redox reaction is that coupling is carried out in the sweet potato tissue, clean, peel, in the process such as incision, and be under the situation of enduring cold, impel redox reaction unbalance, so under oxidasic effect, cause enzymatic browning; In addition, also be rich in sugar and amino acid in the sweet potato, in process, carbonyl in the sugar and the amino generation carbonyl ammonia condensation reaction (claiming Maillard reaction again) in the amino acid generate class melanin, have just caused non-enzymatic browning; Based on enzymatic browning, enzymatic browning is oxidasic catalytic reaction in this two classes brown stain, and abnormal reaction is rapid, makes the very fast blackout of the fresh sweet potato surface of a wound, also produces mashed stink smell when serious.These brown stains make the outward appearance of converted products and mouthfeel all relatively poor, and the consumer is difficult to accept.For above-mentioned reasons, the difficulty that makes the fresh sweet potato of utilization prepare vermicelli strengthens, therefore, and unmanned so far the employing.In addition, no matter adopting sweet potato whole powder or sweet potato starch is the feedstock production vermicelli, exists also that noodles toughness is relatively poor, the section rate is higher, fine and smooth inadequately, and mouthfeel is relatively poor, so their occupation rates in vermicelli market just can only be lower.
Summary of the invention
The present invention seeks to, at adopting bright sweet potato is the brown stain that exists in preparation vermicelli process of raw material and finished product face toughness is relatively poor, frangibility and adopt the defective that the sweet potato starch energy consumption is big, nutriment easily runs off, cost is high, proposing a kind of is raw material with bright sweet potato, flour, be aided with konjaku powder etc., the vermicelli that the lovely luster that processes, good toughness, non-frangibility, mouthfeel be good, be rich in nutriment, favourable health;
Another object of the present invention is the preparation method who proposes these vermicelli.
The object of the invention is achieved through the following technical solutions.
A kind of noodles with fresh sweet potato, the component of these vermicelli and the weight portion of each component are:
Bright sweet potato 500-700 part konjaku powder 2-6 part
Flour 1000-1200 part salt 50-150 part
With water 0-50 part.
Described noodles with fresh sweet potato prescription can further be optimized, and the weight portion of its component and each component is:
6 parts of 700 parts of konjaku powders of bright sweet potato
150 parts of 1200 portions of salt of flour
With 50 parts in water.
