Description
Technical Field
The invention relates to a production process of low gossypol cottonseed meal, belonging to the technical field of cottonseed processing.
Background
At present, about 700 ten thousand tons of cottonseed is produced annually in China, and cottonseed protein is an important plant protein raw material for feeding except bean pulp and rapeseed pulp. The cottonseed protein content is high, the protein content is generally more than 50%, and the protein content can reach more than 60%. Gossypol is the most important anti-nutritional factor in cottonseed protein and is the most important factor influencing the application value of cottonseed protein in feed.
The national requirement limit for free gossypol in cottonseed meal is 1200ppm, and the requirement limit for free gossypol of dephenolized cottonseed protein is 400 ppm. The dephenolized cottonseed protein has low content of free gossypol, and has better application effect in feed formula. However, the dephenolized cottonseed protein is generally extracted by using solvents such as methanol and ethanol, and compared with the common cottonseed meal process, the solvent extraction process is added once, so that the production cost of the product is greatly increased.
At present, the demand of the low gossypol cottonseed protein in the market is increasing day by day, and an economical and efficient low gossypol cottonseed meal production method suitable for large-scale industrial production is urgently needed.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a production process of low gossypol cottonseed meal, which has the advantages of simple process, low production cost and good gossypol removing effect and is particularly suitable for large-scale industrial production.
A production process of low gossypol cottonseed meal comprises the following steps:
(1) adding an acid solution into the cotton kernels for softening and pressing the cotton kernels into embryos, and then extruding and puffing the cotton kernels to obtain cotton embryos;
(2) drying the puffed cotton blank by using superheated steam;
(3) extracting the cottonseed oil from the dried cotton embryo by using an organic solvent to obtain degreased cotton embryo;
(4) and adding water into the degreased cotton embryo, and desolventizing the residue by hot steam to obtain the low gossypol cottonseed meal.
The technical scheme of the invention is further improved as follows: adding an acid solution in the softening process in the step (1), and adjusting the pH range of the cotton kernels to 3-5 and the moisture content of the cotton kernels to 8-12%.
The technical scheme of the invention is further improved as follows: introducing direct steam in the extrusion and expansion process in the step (1), wherein the steam pressure is 0.1-0.3 Mpa.
The technical scheme of the invention is further improved as follows: in the step (2), the pressure of the superheated steam is 0.1-0.4Mpa, and the moisture of the dried cotton embryo is 2-5%.
The technical scheme of the invention is further improved as follows: the organic solvent in the step (3) is a vegetable oil extraction solvent, the material-liquid ratio of the organic solvent to the cotton embryo is 1: 0.5-1: 1, the extraction mode is countercurrent extraction, and the countercurrent extraction times are 6-9.
The technical scheme of the invention is further improved as follows: the water adding amount of the degreased cotton embryo in the step (4) is 5-8% of the weight of the cotton embryo.
The technical scheme of the invention is further improved as follows: in the step (4), the steam pressure is 0.2-0.4 Mpa.
Due to the adoption of the technical scheme, the invention has the beneficial effects that:
(1) the production process is simple and the production cost is low. The invention reduces the working procedure of one-step dephenolizing leaching which is required to be added after the degreasing leaching in the prior conventional low gossypol cottonseed meal process, simplifies the working procedures and reduces the solvent consumption by improving the process of the cottonseed pretreatment and drying working procedures.
(2) The dephenolization effect is good. According to the invention, the content of free gossypol can be greatly reduced in the drying process by puffing the cotton kernels and drying the puffed cotton kernels by using superheated steam. Acid water is added in the softening process to adjust the pH value of the cottonseed, so that the combination of free gossypol and protein can be promoted, and the dephenolization effect is further improved. The technical scheme of the invention can reduce the gossypol content in the cottonseed meal to below 400ppm, meet the gossypol control requirement of dephenolized cottonseed protein, improve the safety of the cottonseed meal, expand the application range of the cottonseed meal, and simultaneously has no adverse effect on the yield and the quality of the cottonseed oil.
