Description
Technical field
The invention belongs to edible bean vermicelli processing technique field, be specifically related to a kind of bean vermicelli that mung bean and pea prepared by fermentation as raw material of take.
Background technology
Bean vermicelli is a kind of traditional food of China, and mainly take mung bean, broad bean, pea, corn, potato, sweet potato etc. is raw material, through extraction process, obtains starch, further by starch gelatinization, moulding, slaking, the technique such as dry, is prepared from.In the raw material of all production beans vermicelli, because the insoluble amylose content of green starch is up to more than 35%, than pea, corn, potato, sweet potato starch etc., exceed 10%, so green bean vermicelli has good, not easily broken of boiling fastness, does not stick with paste soup, boils the feature that loss is little and bean vermicelli mouthfeel is good.But mung bean price is more expensive, resource is less, flour extraction is lower, simple is that Raw material processing bean vermicelli often causes production cost too high with green starch, businessman and consumer are all difficult to bear, therefore, be necessary that the bean starch of seeking performance and green starch is close, cost ratio green starch is cheap reduces the production cost of bean vermicelli.Simultaneously, raising along with economic development and the level of consumption, both at home and abroad the demand of high-quality bean vermicelli is constantly risen, in order to improve the quality of bean vermicelli, each manufacturer has been used food additives to some extent in raw material, such as using alum, gel etc. to improve tough elasticity, boiling fastness and the reduction strip-breaking rate etc. of bean vermicelli, this has just brought the edible safety problem of bean vermicelli.
At present, existing document discloses and has utilized pure green starch, pure pea starch to produce the method for bean vermicelli, but there is no green starch and the composite report for the production of bean vermicelli of pea starch.CN102187979A discloses a kind of preparation method of green bean vermicelli, CN102461803A discloses a kind of method for processing green bean vermicelli, these two kinds of methods all be take pure mung bean as raw material, first prepare green starch, then with green starch, prepare green bean vermicelli, because mung bean price is more expensive, resource is less, flour extraction is lower, causes production cost too high.CN103168986A discloses a kind of production method of green bean vermicelli, raw material also comprises except green starch that tapioca, glutinous rice flour, asparagus, overlord spend, Laoyin tea, mushroom, honeysuckle, sugarcane top, dandelion, hawthorn, ginger, Ilex Latifolia Thunb, folium lycii, roselle, sweet osmanthus and dried orange peel, totally 17 kinds, raw material is too complicated, in order to increase the tough elasticity of bean vermicelli, in preparation process, added edible glue sodium alginate.CN102113653A discloses a kind of pure pea starch noodle and preparation method thereof, and first the method take pea as raw material extracts pea starch, then pea starch is prepared into pea starch noodle, but has added saline solution in powder ball preparation process.Said method is when preparing green starch or pea starch, what adopt is the static immersion of non-circulating water, this immersion way exists that soak time is long, production efficiency is low, raw material local temperature difference is large, soak the problems such as inhomogeneous, and raw material beans is soaked inhomogeneous meeting and causes the problem that flour extraction is low.
Summary of the invention
The deficiency existing for prior art, first object of the present invention is to provide a kind of bean vermicelli that mung bean and pea prepared as raw material of take, to meet people to high-quality, high safety performance bean vermicelli demand; Second object of the present invention is to improve the production efficiency of bean vermicelli, reduces the production cost of bean vermicelli.
For first object of the present invention, natural mung bean pea starch noodle provided by the invention, is to take green starch and pea starch by following method, to be prepared from as raw material, and described preparation method comprises the steps:
(1) mixed powder slurrying: take green starch and pea starch, then add the drinking water of green starch and pea starch dry weight sum 15~35%, mix formation starch slurry;
(2) Lactobacillus plantarum fermentation: to the Lactobacillus plantarum bacterium liquid that adds starch slurry weight 0.1~6.0% in starch slurry, after mixing in 28~37 ℃ of fermentation 8~24h; Total plate count in described Lactobacillus plantarum bacterium liquid is 10
7~10
9cfu/mL;
(3) and slurry beat paste: the drinking water to adding green starch, pea starch and 75~80 ℃ in the starch slurry of fermentation ends, then mixes and is modulated into powder ball; The total amount that adds of described green starch and pea starch is 20~50% of fermentation starch slurry weight, and the addition of drinking water is 10~35% of green starch and pea starch dry weight sum;
(4) leak powder, slaking: powder ball is stirred under vacuum condition to the air of removing in powder ball material, then it is made to bean vermicelli by powder discharger, gained bean vermicelli is placed in to the curing in water sizing of 90~95 ℃;
