Description
Technical field
The present invention relates to food processing fields, and in particular to a kind of starch from sweet potato processing method.
Background technology
The nutritive value of sweet potato is very high, containing multivitamin and trace element, also containing abundant lysine, through often feeding
With nutrition equilibrium is conducive to, so the always favorite food of people.During traditional natural sedimentation producing starch, wherein
When starch lactic acid degree is excessive, starch and protein precipitate simultaneously, and starch separation is ineffective, when starch lactic acid degree is too small, form sediment
Powder and Separation of Proteins are ineffective, in suspension emulsion.Therefore, the processing of starch from sweet potato is unstable since the pH value of wintercherry controls
Fixed, the extraction difficulty for causing starch from sweet potato is larger, and the recovery rate of starch from sweet potato is relatively low.
The content of the invention
Against the above deficiency, it is an object of the present invention to provide a kind of starch from sweet potato processing method, starch from sweet potato is improved
Recovery rate.
To achieve the above object, technical solution provided by the present invention is：A kind of starch from sweet potato processing method, including as follows
Step：
A, the Ipomoea batatas kind for selecting content of starch high removes the sweet potato of lesion；
B, the sweet potato of selection is poured into cylinder and washes and drain away the water；
C, the sweet potato drained is crushed, obtains sweet potato paste；
D, sweet potato paste is diluted with water, the ratio of sweet potato paste and water is 1:3~3.5, it is sufficiently stirred, then first time mistake
Filter, obtains starch milk；
E, under normal temperature state, wintercherry is added in into starch milk, the wherein pH value of wintercherry is 3.6~4.0, the addition of wintercherry
It measures as the 2% of starch milk weight, is then uniformly mixing to obtain mixed liquor；
F, after stirring evenly, staticly settle 20~30 minutes, mixed liquor be divided into the clear swill on upper strata, protein, fiber and
The mixed liquor of a small amount of starch, lower floor is starch, then, extracts the mixed of the clear swill on upper strata, protein, fiber and a small amount of starch
Liquid is closed, then adds water and starch mixing, makes starch reprecipitation, while controlled at 19~22 DEG C, and stir and wintercherry is promoted to send out
Ferment, fermentation after the completion of staticly settle 24 it is small when, top layer is water；
G, upper water is extracted, then the starch after filtering is added water to rinse, when placement 24 is small, taken out by second of filtering of starch
Upper water is taken, takes out starch drying, dress bag.
Preferably, the concentration of the starch milk obtained in step d is 3.5~4.0 Baume degrees.
Preferably, the pH value of the mixed liquor added in step e after wintercherry is 5.6.
Preferably, filtering uses sieve of the aperture for 60 mesh for the first time in step d.
Preferably, second of filtering uses sieve of the aperture for 120 mesh in step g.
Beneficial effects of the present invention are：The present invention uses the pH value of wintercherry to be improved for 3.6~4.0 in process
The recovery rate of starch, and by repeatedly precipitation filter progress, make starch from sweet potato more fair and more clear, mouthfeel is more preferable.
Specific embodiment
The present invention is further described With reference to embodiment：
Embodiment 1
A kind of starch from sweet potato processing method, includes the following steps：
A, the Ipomoea batatas kind for selecting content of starch high, removes the sweet potato of lesion, takes sweet potato 10kg；
B, the sweet potato of selection is poured into cylinder and washes and drain away the water；
C, the sweet potato drained is crushed, obtains sweet potato paste；
D, sweet potato paste 30kg water is diluted, be sufficiently stirred, then filtered for the first time, obtain starch milk；
E, under normal temperature state, wintercherry 0.8kg is added in into starch milk, the wherein pH value of wintercherry is 3.6, and then stirring is equal
It is even to obtain mixed liquor；
F, after stirring evenly, staticly settle 20~30 minutes, mixed liquor be divided into the clear swill on upper strata, protein, fiber and
The mixed liquor of a small amount of starch, lower floor is starch, then, extracts the mixed of the clear swill on upper strata, protein, fiber and a small amount of starch
Liquid is closed, then adds water and starch mixing, makes starch reprecipitation, while controlled at 19~22 DEG C, and stir and wintercherry is promoted to send out
Ferment, fermentation after the completion of staticly settle 24 it is small when, top layer is water；
G, upper water is extracted, then the starch after filtering is added water to rinse, when placement 24 is small, taken out by second of filtering of starch
Upper water is taken, takes out starch drying, dress bag.
Embodiment 2
A kind of starch from sweet potato processing method, includes the following steps：
A, the Ipomoea batatas kind for selecting content of starch high, removes the sweet potato of lesion, takes sweet potato 100kg；
B, the sweet potato of selection is poured into cylinder and washes and drain away the water；
C, the sweet potato drained is crushed, obtains sweet potato paste；
D, sweet potato paste 350kg water is diluted, be sufficiently stirred, then filtered for the first time, obtain starch milk；
