Abstract
The invention discloses a preparation method of arrowhead starch, belonging to the technical field of food processing. The preparation method comprises the following steps of: selecting irregular arrowhead or arrowhead leftover materials, with the diameter below 3cm, as raw materials, soaking the irregular arrowhead for 30-40 minutes in a cleaner filled with water, and washing; crushing the clean arrowhead by using a crusher to obtain arrowhead powder; placing the arrowhead powder into a stirring barrel, adding water, stirring 2-3 times, sedimenting for 3-4 hours, removing floats on the upper part of the stirring barrel and 65-75 percent of water, and repeating 2-3 times; filtering a arrowhead powder solution with a infiltration screen, draining to obtain wet arrowhead starch; baking the wet arrowhead starch for 20-30 minutes by using a baker at 80-90DEG C; and packing and storing. The invention has the advantages of simplicity, convenience, and easy operation and production, and the arrowhead starch prepared by baking with the baker at 80-90DEG C not only preserves nutrition constituents of the arrowhead, but also increases additional value of the arrowhead, thereby improving the enthusiasm of farmers on planting the arrowhead.
Description
Technical field
The invention discloses a kind of preparation method of arrowhead starch, belong to food processing technology field.
Background technology
Arrowhead is a lower fat, low in calories, and the plant of rich vitamin and several mineral materials is a kind of food that is loved by the people.But the arrowhead of plantation is except that section port at present, and major part is consumed as common vegetable.The income of peasant planting arrowhead has only 400-500 unit for every mu, and value-added content of product is very low, influences the enthusiasm of peasant planting arrowhead.With the arrowhead deep processing, increase the arrowhead value-added content of product, improve the enthusiasm of peasant planting arrowhead, be being anxious for of arrowhead plantation family always.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of arrowhead starch.
The objective of the invention is to be achieved through the following technical solutions, the preparation method of arrowhead starch is characterized in that may further comprise the steps:
(1) selects materials: select diameter 3cm following irregular arrowhead or arrowhead scrap stock to make raw material, mildew and rot, rotten, infested person are picked out;
(2) clean: the irregular arrowhead below the diameter 3cm is soaked 30-40 minute in adding the cleaning machine of water after, the coring on the raw material is removed in washing, and in time water washes down;
(3) pulverize: with pulverizer to clean arrowhead scrap stock or the arrowhead after cleaning carry out pulverization process and obtain the arrowhead powder;
(4) precipitation: the arrowhead powder is put into agitation vat, add water, stir 2-3 time, each 5-8 minute, stirring velocity was 5-6 rev/min, precipitates to remove the drift on agitation vat top and the water of 65%-75% after 3-4 hour, repeat settling step 2-3 time, obtain arrowhead powder solution;
(5) filter: with arrowhead powder solution, filter, drain and obtain the wet arrowhead starch of 2000-3000 purpose with web;
(6) baking: wet arrowhead starch was toasted 20-30 minute at 80-90 ℃ with baking machine, make arrowhead starch;
(7) packing: will make arrowhead starch with the laminated bag that is printed on coloured picture and marks relevant criterion and pack, warehouse-in.
The present invention is simple and easy to do, manufactures easily, adopts baking machine at the 80-90 ℃ of arrowhead starch that wet arrowhead starch baking is made, and has both preserved arrowhead starch nutrition composition, has increased the added value of arrowhead again, has improved the enthusiasm of peasant planting arrowhead.
Embodiment
Select diameter 3cm following irregular arrowhead or arrowhead scrap stock to make raw material, mildew and rot, rotten, infested person are picked out.Irregular arrowhead below the 3cm of footpath soaked 30-40 minute in adding the cleaning machine of water after, the coring on the raw material is removed in washing, and in time water washes down.The arrowhead scrap stock are scrap stock of not using when making other arrowhead food, are what to clean, so directly enter shredding stage.With pulverizer to the arrowhead scrap stock or/and the arrowhead after cleaning carries out pulverization process, filter with web, obtain 2000-3000 purpose arrowhead powder.The arrowhead powder is put into agitation vat, add water, stir 2-3 time, each 5-8 minute, stirring velocity per minute 5-6 changeed, and precipitates and removes the drift on agitation vat top and the water of 65%-75% after 3-4 hour, repeats to precipitate 2-3 time, obtains arrowhead powder solution.Arrowhead powder solution is filtered with web, drain, the arrowhead starch that obtains wetting.Wet arrowhead starch is evenly placed on the baking machine,, make arrowhead starch in 80-90 ℃ of baking 20-30 minute.To make arrowhead starch with the laminated bag that is printed on coloured picture and marks relevant criterion and pack, every bag of 250-500 gram (or as required), vanning is sealed with wrapping machine, the external application adhesive tape case mouth of obturaging, warehouse-in.
