Abstract
The invention relates to the field of food processing and in particular discloses a sweet potato powder treatment process. The process comprises the following steps: treating raw materials; crushing; grinding and filtering; pulping; skimming a jar and performing acid slurry fermentation; discharging the pulp; discharging the powder; and drying. According to the sweet potato powder treatment process provided by the invention, the process is simple, the preparing cost is low, and the produced sweet potato powder is fine and smooth and good in taste. Meanwhile, calcium and magnesium in the produced sweet potato starch are easy to absorb, and the effects of preventing osteoporosis and reducing the blood pressure can be achieved.
Description
Technical field
The present invention relates to food production field, specifically disclose a kind of sweet potato powder treatment process.
Background technology
Along with the development of society, people are also improving constantly the requirement of self living standard.Ipomoea batatas relies on the abundant nutrition value of self containing to be brought up to dining table by increasing people.But single edible Ipomoea batatas can not meet the diverse requirements of people to food.Therefore, the starch that Ipomoea batatas machining obtains becomes one of food indispensable in people's daily life.
Summary of the invention
In order to solve the technical problem existed in prior art, the object of the present invention is to provide a kind of sweet potato powder treatment process, its technological process is as follows: Feedstock treating, and---broken---------------playing powder---is dry to skim slurry to skim cylinder and fermented wintercherry to convert slurry to grind filtration, technique is simple, low cost of manufacture, and the sweet potato powder produced is fine and smooth, mouthfeel is good.
The technical solution adopted in the present invention is as follows:
A kind of sweet potato powder treatment process, comprises the steps:
(1) Feedstock treating: select new fresh sweet potatoes, removes Ipomoea batatas in spite of illness, is poured in cylinder by the fresh potato selected and adds supernatant water, with manually carrying out turning over washing, washing rear taking-up, draining Yu Shui;
(2) broken: the fresh potato disintegrating machine after draining breaks into fragment, and the size of block is that below 2cm is for subsequent use;
(3) grind filtration: fresh potato fragment is sent into stone mill or Buddha's warrior attendant sand milling and add water and wear into potato and stick with paste, then potato to be stuck with paste impouring aperture be filter in 60 object sieves;
(4) convert slurry: the starch milk obtained after filtration puts into vat, add acidity and the concentration of wintercherry and water adjustment starch milk immediately in proportion;
(5) cylinder and fermented wintercherry is skimmed: after converting slurry, about leave standstill 20 ~ 30 minutes, precipitation is completed, can carry out slash cylinder, be taken out by the mixed liquor of clear for upper strata swill and protein, fiber and a small amount of starch, what stay bottom is starch, add water in bottom starch after skimming cylinder mixing, furnishing starch milk, makes starch precipitate again, plays fermented wintercherry effect in precipitation process, ferment complete, starch sedimentation;
(6) skim slurry to filter: namely skim slurry is use upper strata wintercherry skimmed as converting slurry, skim slurry after starch sieve aperture be 120 dusting cover sieve, oversize is thin slag, screenings is starch, proceed to little cylinder, after starch proceeds to little cylinder, add water rinse starch, about need placement 24 hours, prevent fermentation phenomenon;
(7) powder is played: after starch precipitates in little cylinder, supernatant liquid is little slurry, can with wintercherry with the use of, or as grinding with water, after skimming little slurry, the greyish white oil-bound distemper of one deck is left on starch surface, the impure starch of system containing protein, oil-bound distemper available water washes away from starch surface, and bottom starch scoop takes out, fine sand may be had bottom starch to adhere to, brushed away;
(8) dry: to adopt daylight to dry wet starch or send into drying room and dry.
The precipitation of the acidity of starch milk and concentration and starch and protein has substantial connection.If starch milk acidity is excessive, starch and protein precipitate simultaneously, make starch separation unclear.Acidity is too small, then protein and starch all precipitate bad, in emulsion, cannot be separated.
Further, in described step (3), the ratio of fresh potato weight and amount of water is 1:3 ~ 3.5.
Further, in described step (4), wintercherry optimal pH is 3.6 ~ 4.0.In vat, starch concentration is 3.5 ~ 4.0 Baume degrees, add that wintercherry amount is starch milk 2%, and after adding wintercherry, the pH value of starch milk is 5.6.
Further, in described step (5), fermented wintercherry operative temperature is 20 degrees centigrade.The fermented wintercherry time is 20 ~ 24 hours.
Sweet potato powder treatment process of the present invention, its beneficial effect shows:
Technique is simple, low cost of manufacture, and the sweet potato powder produced is fine and smooth, and mouthfeel is good; Produce calcium in starch from sweet potato and magnesium is easy to absorb simultaneously, can prevention of osteoporosis disease and the effect that reduces blood pressure.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated.
