Point content is higher, and metabolism is vigorous, not shelf-stable and transport, is easy putrid and deteriorated, and Chinese chestnut dries in processing that there is also discolorations
The problem of influencing quality, starch contained in Chinese chestnut are underutilized.Acorn nut is the general name of Fagaceae oak plant seed,
Every hectogram kernel contains 8 grams of protein, and 2 grams of fat, 50~65 grams of carbohydrate, 1.3 grams of dietary fiber, thiamine 0.03 is micro-
Gram, 7 milligrams of vitamin C, 112 milligrams of calcium, 64 milligrams of phosphorus, 5.8 milligrams of iron, 7~17 grams of tannin, content of starch is up to 60%,
However, producing acorn nut powder firstly the need of the most of tannin of removing to remove acorn nut astringent taste, but tannin is rubber again because acorn nut astringent taste is strong
Main functional component in sub- benevolence, it is crucial for how guaranteeing that its functional component is not damaged while removing acorn nut astringent taste.Seven leaves
Tree is the deciduous tree of soapberry wood Hippocastanaceae, and aesculus seed is edible or medicinal, straight although wherein content of starch is high
It is bitter to connect jealous road, need to boil that rear is edible with buck, there is no the method for effective use wherein starch at present.
Summary of the invention
The problems of in the prior art for solution, the first purpose of technical solution of the present invention is to provide a kind of gel use
Woody compound starch.
The second object of the present invention is to provide the above-mentioned gel preparation method of woody compound starch.
To achieve the above object, the embodiment of the present invention uses following technical scheme:
A kind of woody compound starch of gel, the component including following parts by weight meter:
80~120 parts of woody starch,
2~10 parts of pea starch.
Preferably, the woody starch is the mixing of chestnut starch, acorn starch and seven leaf fruit starch.
Preferably, the pea starch is black pea starch and white pea starch is 1:(5~10 in mass ratio) mixing
Object.
It is further preferred that the mass ratio of the chestnut starch, acorn starch and seven leaf fruit starch is (5~10): (5~
10): (20~35).
It is further preferred that the mass ratio of the chestnut starch, acorn starch and seven leaf fruit starch is 7:7:28.
The preparation method of the woody compound starch of above-mentioned gel, the preparation method is that: the woody shallow lake is weighed according to the ratio
It is mixed after powder and pea starch.
Preferably, step includes:
(1) water is added after crushing chestnut kernel, Chinese chestnut slurry is made, be washed with water after the Chinese chestnut slurry is displayed,
It is dry, obtain chestnut starch;
(2) water is added after crushing acorn nut kernel, acorn nut slurry is made and displays, will distinguish by the acorn nut slurry displayed
It is dry after being cleaned with water and dilute alkaline soln, obtain acorn starch;
(3) water is added after crushing seven leaf fruits, seven leaf fruit slurries are made and displays, by the seven leaf fruit slurries point by displaying
It is dry after not cleaned with water and concentrated alkali solution, obtain acorn starch;
(4) it weighs pea starch according to the ratio and chestnut starch, acorn starch and seven leaf fruits that step (1)~(3) obtain is formed sediment
Powder, after mixing to obtain the final product.
It is further preferred that step (2) described dilute alkaline soln be the sodium carbonate that mass percent concentration is 0.5~20% or
Sodium bicarbonate solution.
It is further preferred that step (3) described concentrated alkali solution be the sodium carbonate that mass percent concentration is 25~35% or
Sodium bicarbonate solution.
It is further preferred that the time displayed is 5~12h.
Chestnut starch also has treatment gastric disorder causing nausea, haematemesis, hematochezia, pyogenic infections and other effects other than full of nutrition.
