Abstract
The present invention relates to vegetal protein feed, particularly to a technique for preparing cottonseed protein by detoxifying cottonseed cakes (meal). 10 to 35 portions of cottonseed cakes (meal) sieved by a sieve of 10 to 100 meshes are added into 40 to 100 portions of 0.01 to 10% acidic solution; after the cottonseed cakes (meal) and the acidic solution react for 0.1 to 5 hours at the temperature of 50 to 100 DEG C, liquid is centrifugally separated to obtain solid material; then 40 to 100 portions of 0.01 to 10% alkaline solution reacts with the solid material for 0.1 to 5 hours at the temperature of 50 to 100 DEG C to obtain the product through separation and drying. The product produced by the present invention eliminates free gossypol and combination gossypol, increases the protein content of cottonseeds and has the characteristics of strong detoxification capability, advanced technology, safe and reliable production, high product level, etc.
Description
The present invention relates to vegetable protein feed, the technology of cottonseed protein is produced in cottonseed cake or dregs of rice detoxification specifically.
China is one and produces cotton big country that the cottonseed cake resource is very abundant, about 400～5,000,000 tons of annual production.Protein content in the cottonseed cake is about 40%, and is suitable with soybean cake substantially; Compare with wheat with rice, protein content exceeds 5～8 times.After the cottonseed cake hydrolysis, can obtain 17 seed amino acids.Therefore, cottonseed cake is the same with soybean cake, is a kind of source best in quality rich vegetable protein feed.Yet, owing to contain a spot of noxious material--gossypol in the cottonseed cake, and can not effectively utilize, major part can only be used as fertilizer, and is very unfortunate.Supply falls short of demand for China's protein feed on the other hand, do not satisfy the needs of feed industry develop rapidly, has to from external a large amount of imported fish meals.Therefore, animal husbandry market an urgent demand exploitation China cottonseed protein resource.
Gone to do a lot of work aspect every in cottonseed processing both at home and abroad since the fifties, as the further boiling of cottonseed cake, steam heat spray, solvent leaching again, alkaline process, ferrous sulfate processing, microbial fermentation, UV-irradiation etc. are obtained certain effect among a small circle.But because the not thorough reasons such as (free gossypol are generally about 0.04% in the product) of detoxification fails to apply on a large scale.
The purpose of this invention is to provide a kind of more thoroughly, and can improve the process of cottonseed protein content cottonseed cake or dregs of rice detoxification.
Technical essential of the present invention is:
To cross 10～35 parts of the cottonseed cake of 10～100 mesh sieves or the dregs of rice by weight, add that to be selected from formic acid, acetate, propionic acid, butyric acid, boric acid, sulfuric acid, hydrochloric acid, concentration of phosphoric acid be 40～100 parts of 0.01～10% acids solution, after temperature was to react 0.1～5 hour under 50～100 ℃ of conditions, the centrifugal liquid of telling got solid material; This solid material is 40～100 parts of 0.01～10% bases solution with being selected from NaOH, calcium hydroxide, magnesium hydroxide, potassium hydroxide, sodium carbonate, potash, sodium acid carbonate, saleratus, ammoniacal liquor, concentration of ammonium carbonate again, in temperature is to react 0.1～5 hour under 50～100 ℃ of conditions, through isolating for the second time solid material, the dry product that gets.
The cottonseed protein that the present invention is given has removed free gossypol and in conjunction with gossypol, it is strong to have the detoxification ability, characteristics such as advanced technology, production safety are reliable, product specification height.Free gossypol residual quantity 0.01～0.026% removes 40～80% in conjunction with gossypol in the product.Cottonseed protein content 40～53% is higher than soybean cake in the product, approaches fish meal.The cottonseed protein yield is more than 90%.This product can all replace soybean cake to raise commodity egg with part as the protein sources component (adding 10～18%) of mixed feed, and not only not having makes pottery eliminates, and nothing is dead, and makes egg production increase production 4～25%.Replace soybean cake to add 20% in concentrated feed with this product, breeding milk cow is not observed toxic reaction, and the output of milk and soybean cake remain basically stable.
Said acids solution is formic acid, acetate, propionic acid, butyric acid, boric acid, sulfuric acid, hydrochloric acid, phosphoric acid etc. among the present invention; Bases solution is NaOH, calcium hydroxide, magnesium hydroxide, potassium hydroxide, sodium carbonate, potash, sodium acid carbonate, saleratus, ammoniacal liquor and ammonium carbonate etc.The used equipment of separation circuit is centrifuge, filter press, rotary filter etc.; Material after separating for the second time should be dried to water content≤12%.
Embodiment:
1. the hydrochloric acid solution and the 20 kilograms of cottonseed cakes (free gossypol 0.142%, total gossypol 0.992%, crude protein 47.46%) that add 50 liters 0.1% in 100 liter reactors were 80 ℃ of reactions 2 hours.Centrifugal tell liquid after, material in 100 liter reactors and the sodium carbonate liquor of 50 liters 0.1% under 80 ℃ of conditions, react 2 hours, through centrifugal tell liquid after product dry.Free gossypol 0.009%, total gossypol 0.262%, crude protein 53.19%, crude protein yield 92.5%.
2. the hydrochloric acid solution and the 20 kilograms of cottonseed dregs of rice (free gossypol 0.092%, total gossypol 1.016%, crude protein 36.53%) that add 50 liters 0.2% in 100 liter reactors were 80 ℃ of reactions 2 hours.Reactant after telling liquid, solid material in 100 liter reactors and the sodium carbonate liquor of 40 liters 0.20% under 80 ℃ of conditions, reacted 2 hours.Product is dried after telling liquid, free gossypol 0.013%, and total gossypol 0.260%, cottonseed protein are 40.91%, cottonseed protein yield 92%.
Claims (2)
1. the cottonseed protein method is produced in cottonseed cake or dregs of rice detoxification, it is characterized in that to cross by weight 10～35 parts of the cottonseed cake of 10～100 mesh sieves or the dregs of rice, add that to be selected from formic acid, acetate, propionic acid, butyric acid, boric acid, sulfuric acid, hydrochloric acid, concentration of phosphoric acid be 40～100 parts of 0.01～10% acids solution, after temperature was to react 0.1～5 hour under 50～100 ℃ of conditions, the centrifugal liquid of telling got solid material; This solid material is 40～100 parts of 0.01～10% bases solution with being selected from NaOH, calcium hydroxide, magnesium hydroxide, potassium hydroxide, sodium carbonate, potash, sodium acid carbonate, saleratus, ammoniacal liquor, concentration of ammonium carbonate again, in temperature is to react 0.1～5 hour under 50～100 ℃ of conditions, through isolating for the second time solid material, the dry product that gets.
