Abstract

The production method of pure white vermicelli by using sweet potato and potato includes the following steps: using 100 portions of sweet potato raw paste, adding 10 portions of fermented starch paste to obtain their mixture, mesh-filtering, separating and sealing with clear water to obtain pure white starch, then blending material, forming, cooling and drying so as to obtain the invented pure white vermicelli. Said invention is reasonable in technological process, convenient in operation, and said product vermicelli is silvery white in colour, palatable in taste, soft and smooth in mouth feel and possesses sweet-taste of natural sweet potato.

Description

The production method of whole sweet potato white vermicelli

The present invention relates to a kind of production method of producing white vermicelli with Ipomoea batatas, potato.

The production method of producing at present potato vermicelli comprises the cleaning of potato (Ipomoea batatas, potato), pulverize defibrination, separate to remove slag and make starch, adopts the chemical method decolouring, and batching is made bean vermicelli.

Though this method has many advantages, also exist many technological deficiencies.Adopt the decolouring of oxidant sodium sulfite or sodium hydrogensulfite, decolorizing effect is relatively good, but this inorganic matter belongs to sulfide, contain the Sulfur flavor, in decolouring, potato starch is polluted, lose the nutritive value of tuber crops food, more can not classify the potato vermicelli of producing in this way as the pollution-free food category.

Purpose of the present invention just provides a kind of production method of producing whole sweet potato white vermicelli.

The object of the present invention is achieved like this: the production method of whole sweet potato white vermicelli comprises that defibrination, screen cloth are cleaned, pulverized to bright potato (not removing the peel) or dried sweet potato to be separated and remove slag, make starch slurry and through precipitation, this method also comprises following processing step:

A. silt, impurity are removed in above-mentioned starch fluid refining, venting yellow lake powder;

B. add the ratio of 10 fens wintercherry water in the starch fluid (Ipomoea batatas virgin pulp liquid) of 100 fens a flow processs, make starch from sweet potato wintercherry mixing water, separate through screen filtration, remove the yellowish toner in top layer, limpid to water, pH value through the clear water sealing, is made pure white starch again at 4-5;

C. connect 100 fens pure white starch fluids (content of starch is 35-40%), add salt 0.1-0.25 kilogram, edible oil 0.03-0.05 kilogram, edible alum 0.001-0.025 kilogram, make mixed liquor through mixing to stir;

D. above-mentioned mixed liquor is made bean vermicelli and made whole sweet potato white vermicelli through cooling, drying.

The present invention compares with prior art, has following advantage:

1, the full sweet potato vermicelli that adopts the present invention to produce is a natural green food, particularly the Ipomoea batatas of this product is all taken from the mountain area, Daba Mountain Wanyuan of rich selenium, in conjunction with brand-new biodecolouring process, the bean vermicelli color and luster is silvery white in color, mouthfeel is soft moist good to eat, with the fragrant and sweet flavor of Ipomoea batatas of nature.

2, owing to adopt biodecolouring process, not sulfur compound and any harmful chemical, sweet potato noodles is not subjected to any pollution, do not contain any anticorrisive agent, simultaneously because this product is rich in natural organic selenium, satisfy people and thirsted for from wholefood, mending an urgent demand of selenium, thereby had wide commercial market prospect.

3. add certain salt in batching, the product mouthfeel is better; Improved the boiling fastness of at present full sweet potato vermicelli, reduced strip-breaking rate, the instant bean vermicelli outward appearance of producing is better, more gets consumer reception.

4, the bean vermicelli that adopts the present invention to produce, owing to discharged silt, impurity thoroughly, effectively, color and luster is pure whiter, mouthfeel is finer and smoother, and is salubriouser.

5, the full sweet potato vermicelli that adopts the inventive method to produce, dietary fiber and the multivitamin of Ipomoea batatas do not go to pot, and normal eating can be prevented constipation, makes stool unimpeded, the generation of the anti-system person in middle and old age carcinoma of the rectum.

6, technology of the present invention is simple, reasonable.As in Ipomoea batatas magma, directly adding wintercherry water, not only simplified technology, and it is convenient and easy to operate.

Further be illustrated below by specific embodiment, but be not limited only to following examples.

The production method of whole sweet potato white vermicelli comprises following technology:

1, washes potato: scarlet potato (not removing the peel) or dried sweet potato are cleaned in water spray or circulating water;

2, pulverizing, defibrination: Ipomoea batatas of cleaning or potato are done pulverizing mushroom one-tenth potato slurry in the input fiberizer;

3, the screen cloth separation is removed slag: the potato slurry is isolated the potato slag through 120 eye mesh screens;

4, precipitation: the starch slurry that will remove slag is conveyed into stillpot, makes starch;

5, refining: above-mentioned starch is sent into refining discharge silt, impurity in the purifier;

6, decolouring:, make starch wintercherry mixing water, through 120 eye mesh screen isolated by filtration by the ratio of 10 fens wintercherry water of the starch fluid (Ipomoea batatas magma) of 100 lease making refinings adding, remove the yellowish toner in top layer, limpid to water, pH value is controlled at 4-5, through the clear water sealing, make pure white full sweet potato starch again;

7, spice: by 100 fens pure white starch fluids (content of starch is 35-40%), add salt 0.1-0.25 kilogram, edible oil 0.03-0.05 kilogram, edible alum 0.001-0.025 kilogram,, make mixed liquor through mixing;

8, powder process silk: the mixed liquor of scattered paste shape is made bean vermicelli through vermicelli machine;

9, cooling: through cooling off naturally or being conveyed into the freezer cooling, bean vermicelli changes software strategy into software-hardware strategy;

10, open powder: the bean vermicelli of cooling is through rubbing scattered or vibrating into loose shape;

11, dry, packing: send in the dryer oven dry or under natural daylight, dry opening bean vermicelli behind the powder, again through cutting, pack, make finished product.

Claims

1, the production method of whole sweet potato white vermicelli comprises that defibrination, screen cloth are cleaned, pulverized to scarlet potato (not removing the peel) or dried sweet potato to be separated and remove slag, and makes starch slurry and through precipitation, it is characterized in that this method also comprises following technology:

B. add the ratio of 10 fens wintercherry water in the Ipomoea batatas magma of 100 fens a flow processs, make starch wintercherry mixing water, separate, remove the yellowish toner in top layer through screen filtration, limpid to water, through the clear water sealing, make pure white starch again;

C. by 100 fens pure white starch fluids, add salt 0.1-0.25 kilogram, edible oil 0.03-0.05 kilogram, edible alum 0.001-0.025 kilogram,, make mixed liquor through mixing;
