Abstract

An edible coarse soybean protein powder is prepared from fresh soybean dregs through adding alkali, flour and water, biochemical treating, dewatering, baking, cooling pulverizing and sieving, or through fermenting, dewatering, drying, adding broken corn grains, puffing, pulverizing and sieving. Its advantages are rich nutrients including Fe, Ca, Se, P and isoflavone and health-care function.

Description

Process for preparing edible coarse protein powder from soybean

The present invention relates to a kind of preparation method of plant crude protein, particularly from the soybean bean dregs, produce the method for edible crude protein powder.

People stay a certain amount of bean dregs always making in the process of bean product such as bean curd of soybean, according to detection, contain calcium, iron, selenium, phosphorus in the bean dregs, the essential composition of multiple health such as isoflavones particularly, and its content surpasses bean product.For a long time, bean dregs are used as and feed pigs, the treated seldom again health food that is of value to health of people of making, and this is a kind of great waste really.

The objective of the invention is to remedy the deficiencies in the prior art, provide that a kind of processing ease, bean dregs utilize, the preparation method of added value height, good in economic efficiency edible coarse protein powder from soybean again.

Technical scheme of the present invention is: after a kind of processing of bright bean dregs in following two kinds of methods, obtain the crude protein powder.Method one: in bright bean dregs, add alkali, flour and water, stir the back biochemical treatment, dewater again, dry, cool off, pulverize, sieve, promptly obtain the crude protein powder; Add alkali 10～40g in the bright bean dregs of every 2.5kg, add flour 15～150g, add water 200～400g.Method two: after bright fermenting bean dregs processing, dehydration, the drying, add broken iblet or fritter potato in etc. agricultural byproducts, mix thoroughly, after expanding treatment, cool off, pulverize, sieve, promptly get the crude protein powder; After the bright bean dregs dehydration of every 2.5kg, add 10～70% broken iblets or other agricultural byproducts.

In the said method, in oven dry or the drying process, make moisture content drop to 10～20%, temperature is 120～180 ℃ during described expanding treatment, and the back finished product granularity of sieving is 40～260 orders, and oversize material row is again pulverized, and recycles.

Add alkali among the present invention, help bean dregs to decompose, change its molecular structure, absorbed by human consumption easily, adding flour can tackify, and plays whitening effect; Add broken iblet or other agricultural byproducts, and carry out expanding treatment, then further balanced nutrients composition, mouthfeel is better.The present invention operates easily, does not need much investments, can effectively utilize the soybean slag charge, and produce human nutrition, healthy very useful edible crude protein, and then make good to eat non-staple food and leisure food, the added value height, good in economic efficiency.

Further specify the embodiment of the invention below.

Example one: bright bean dregs 25kg adds dietary alkali 0.3kg, flour 1kg, water 3kg, stir the back biochemical treatment, carry out extrusion dehydration again, driven type is dried to moisture content and is dropped to about 15%, is cooled to normal temperature, roll pulverizing, cross 100 mesh sieve, promptly obtain the crude protein powder, the residue material utilizes again on the sieve.

Example two: bright bean dregs 25kg, fermentation process dehydrates to moisture content and drops to about 15%, adds broken iblet 4kg, mixes thoroughly, and the expanding treatment temperature is 140 ℃, is cooled to normal temperature, rolls pulverizing, and 150 orders that sieve promptly get the crude protein powder, and residue utilizes again on the sieve.

Claims

1, a kind of process for preparing edible coarse protein powder from soybean is characterized in that obtaining the crude protein powder with after a kind of processing of bright bean dregs in following two kinds of methods;

Method one: in bright bean dregs, add alkali, flour and water, stir the back biochemical treatment, dewater, dry, cool off, pulverize, sieve, promptly get the crude protein powder, add alkali 10～40g in the bright bean dregs of every 2.5kg, add flour 15～150g, add water 200～400g;

Method two: after bright fermenting bean dregs processing, dehydration, the drying, add broken iblet, mix thoroughly, after expanding treatment, cool off, pulverize, sieve, promptly get the crude protein powder, after the bright bean dregs dehydration of every 2.5kg, add 10～70% broken iblets.

2,, it is characterized in that making moisture content drop to 10～20% in oven dry or the drying process by the described crude protein powder of claim 1 preparation method.

3, by the described crude protein powder of claim 1 preparation method, temperature is 120～180 ℃ when it is characterized in that expanding treatment.
