Description

A method of potato rice flour is made with the fresh sweet potato containing anthocyanidin
Technical field
The invention belongs to rice flour processing technique fields, specifically provide a kind of with the fresh sweet potato production potato containing anthocyanidin The method of rice flour.
Background technique
Osmanthus coloured silk potato is the Potato Cultivars in the area south China Dong Zuo, compared with common Potato Cultivars, is rich in cyanine Element, nutritional ingredient are higher.Its harvest season is generally annual 3-5 month, at this time exactly season of high temperature and rainy, the horse of harvest Bell potato fresh sweet potato water content is larger, it is easy to rot, be also unsuitable for long-distance outward transport, it is easy to occur unsalable, influence peasant's Income, influences the stability of Development of Potato Industry.If can process on the spot, it will well solve this problem.
Potato deep processing is mainly potato starch processing, and added value is not high.Potato fresh sweet potato is needed by washing Wash, grind, sieving, protein isolate matter, cleaning, the processes such as dehydration and drying can just be processed into potato starch, process is tedious, and In process, it will cause the loss of nutritional ingredient, also will increase pollution sources.Potato rice flour is a horse developed in recent years The far super common pure rice flour of bell potato deep processed product, nutritive value and mouthfeel.Potato rice flour on the market is typically all to use Potato starch and rice are mixed, rather than are directly prepared by potato fresh sweet potato.And the additive amount of potato is not high(Horse The additive amount of bell potato improves the strip-breaking rate that can improve rice flour).In addition, common potato rice flour is free of anthocyanidin, it is not able to satisfy Diversification of the people to things, health demand.
Summary of the invention
The purpose of the present invention is overcoming drawbacks described above, provide it is a kind of be more suitable for batch production popularization and application with containing anthocyanidin The method of fresh sweet potato production potato rice flour.
Technical solution of the present invention:A method of potato rice flour, the potato are made with the fresh sweet potato containing anthocyanidin The component of rice flour is by weight percentage:Osmanthus coloured silk potato potato fresh sweet potato 40-50% that wash clean is peeled, it impregnates and drains rice 50- 60%;
Method using said components production potato rice flour includes the following steps:
(1)Weighing will be impregnated and drained after rice wash clean, it is stand-by to wear into rice flour;
(2)After osmanthus coloured silk potato potato fresh sweet potato wash clean is peeled by weight(8-9):(1-2)It is divided into two parts, that part of weight weight Slurries are worn into after crushing and are sealed installs;That light-weight part smashs into mashed potato to pieces after cooking;
(3)By step(1)With(2)Rice flour, potato slurries, mashed potato be uniformly mixed;
(4)By step(3)Mixture be put into rice flour squeezer silk pressing semi-finished product rice flour, the extruding temperature in rice flour squeezer be made Degree is set as 105-115 DEG C;
(5)By step(4)Semi-finished product rice flour be put into the baked Fang Nei of closed baked powder 6-10 hours;
(6)By step(5)Processed semi-finished product rice flour carries out loose powder moulding;
(7)By step(6)Processed semi-finished product rice flour is put into barn drying;
(8)By step(7)Processed rice flour is packed to arrive finished product rice flour.
Further, step(1)In, it is impregnated 4-6 hours after rice wash clean with tap water at normal temperature.
Further, step(2)In, the osmanthus coloured silk potato potato fresh sweet potato is held after wearing into slurries with slot bucket, then uses bucket Lid or preservative film sealing, avoid and the big and easy to oxidize discoloration in air contact surfaces.
Further, step(3)In, it is placed in closed container, reduces after rice flour, potato slurries, mashed potato mixing Oxidation.
Further, step(4)In, the extruding temperature setting in the rice flour squeezer is 110 DEG C.Be conducive to be passivated fresh Enzyme in potato.
Further, step(5)In, baked room totally-enclosed is not light-exposed.
Further, step(5)In, Chang Wen fills in steam Dao baked room 10-20 minutes after baked powder 4-6 hours.
Further, step(7)In, the barn temperature is 25-35 degree, and drying time is 10-12 hours.
Further, the rice is old rice.I.e. using non-this season harvest, but the rice of a period of time is placed to do Rice flour, can reduce the broken strip of finished product rice flour, and the stability of finished product rice flour is higher.
Advantage of the present invention:1, the present invention makes potato rice flour using the osmanthus coloured silk potato potato fresh sweet potato rich in anthocyanidin, And optimize manufacture craft, compared with using potato starch production potato rice flour, it can be carried out after potato fresh sweet potato harvest The processing of rice flour is processed into the processing such as starch without being dried, can reduce manufacturing procedure and pollution, reduce cost, and can subtract Oligotrophic loss(In potato slag and molten nutriment in water), improve the nutritive value of rice flour;And locality can be solved on the spot Peasant sells the problem of potato hardly possible.
2, the method for the present invention mixes after rice and potato are worn into rice flour and potato slurries, and potato is further absorbed and utilized Moisture in slurries improves the nutritional ingredient of finished product rice flour;Meanwhile powder processed is remixed after cooking part potato, it can increase The toughness of finished product rice flour reduces strip-breaking rate, while the additive amount of potato fresh sweet potato also can be improved, and the nutrition for improving finished product rice flour contains Amount(Also contain a large amount of anthocyanidin while containing potato nutritional ingredient).Semi-finished product rice flour is suppressed using high temperature, can be passivated potato In enzymatic activity can extend the shelf-life of finished product rice flour in this way while guaranteeing quality of rice noodles.
Specific embodiment
Present invention will be further explained below with reference to specific examples.
