Problems solved by technology

[0012] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing rapeseed meal detoxification reaction, such as incomplete detoxification, large geographical restrictions, affecting the nutritional value of rapeseed meal, high cost or difficult to popularize equipment, etc., and When the content of rapeseed meal in the feed exceeds 2-5%, it will make the feed black, which is not conducive to sales and use, and the decolorization reaction alone will increase the defect of the process burden, thereby providing a kind of rapeseed meal and its processing Method, and feed containing the rapeseed meal

Embodiment 1

[0039] The influence of embodiment 1 food-grade sodium bicarbonate on the decolorization of rapeseed meal

[0040] 1. The concentration of sodium hydrosulfite affects the decolorization of rapeseed meal

[0041] (1) Detoxification and decolorization of rapeseed meal: heat samples 1 to 5 in a constant temperature water bath at 80° C. for 20 minutes.

[0042] Among them, sample 1 is obtained by mixing 40 g of sodium hydrosulfite aqueous solution with a concentration of 0.1% and 60 g of rapeseed meal. In sample 1, sodium hydrosulfite accounts for 0.04%, water accounts for 39.96%, and rapeseed meal accounts for 60%.

[0043] Sample 2 is obtained by mixing 40 g of 0.3% sodium hydrosulfite aqueous solution and 60 g of rapeseed meal. In sample 2, sodium hydrosulfite accounts for 0.12%, water accounts for 39.88%, and rapeseed meal accounts for 60%.

[0044] Sample 3 is obtained by mixing 40 g of sodium hydrosulfite aqueous solution with a concentration of 0.5% and 60 g of rapeseed me...

Embodiment 2

[0063] Embodiment 2 The influence of food-grade sodium bicarbonate on the decolorization of rapeseed meal

[0064] (1) Detoxification and decolorization of rapeseed meal: heat samples 6 and 7 in a constant temperature water bath at 80° C. for 20 minutes.

[0065] Among them, sample 6 is obtained by mixing 30 g of sodium hydrosulfite aqueous solution with a concentration of 0.4% and 70 g of rapeseed meal. In sample 6, sodium hydrosulfite accounts for 0.12%, water accounts for 29.88%, and rapeseed meal accounts for 70%.

[0066] Sample 7 is obtained by mixing 60 g of sodium hydrosulfite aqueous solution with a concentration of 0.9% and 40 g of rapeseed meal. In sample 2, sodium hydrosulfite accounts for 0.54%, water accounts for 59.46%, and rapeseed meal accounts for 40%.

[0067] (2) Detoxification again: the rapeseed meal treated in step (1) was mixed with FeSO 4 ·H 2 O mixed, heated, expanded; the rapeseed meal and FeSO 4 ·H 2 The mixing mass ratio of O is 100:0.5; the di...

Embodiment 3

[0069] Example 3 The influence of food-grade sodium bicarbonate on the detoxification of rapeseed meal

[0070] (1) Detoxification and decolorization treatment of rapeseed meal: 1 ton of sample 3 was steam heated at 80° C. for 15 minutes.

[0071] (2) Detoxification again: the rapeseed meal treated in step (1) was mixed with FeSO 4 ·H 2 O mixed, heated, and dried under reduced pressure; the rapeseed meal and FeSO 4 ·H 2 The mixing mass ratio of O is 100:0.2.

[0072] (3) Determination of TTC and OZT content according to national standards GB13087-91 and GB13089-91, the results are shown in Table 1.

[0073] Table 1 Pilot detoxification results of rapeseed meal (mg / kg)

[0074] deal with

[0075] It can be seen from Table 1 that the processing method of the present invention has a detoxification rate of 96.05% for rapeseed meal, making the residual poison of rapeseed meal less than 0.2 mg / kg, reaching the domestic leading level.

Abstract

The invention relates to an animal feed, and provides a processing method of rapeseed meal, the method comprises the following steps: detoxificating and decolouring of the rapeseed meal, mixing sodium dithionite, rapeseed meal with water and heating. The invention overcomes the defects of incomplete detoxification, large restriction of geography, influenced nutrition value of rapeseed meal, high cost or difficult popularization of equipments in the present detoxification reaction of rapeseed meal, and when the rapeseed meal content in feed exceeds 2-5%, the feed turns black and is unbeneficial to the sale and usage, so that the invention provides the rapeseed meal and its processing method, and the animal feed containing the rapeseed meal. The processing method of the rapeseed meal realizes a continuous processing of detoxificating and decolouring of the rapeseed meal at same time, and has the advantages of low cost for decolouring, good detoxificating efficiency with residual toxic dose less than 0.2 mg / kg, high safety performance and simple technology, the rapeseed meal and its processing method are suitable for industrial application, and the adding proportion of the processed rapeseed meal can reach 5-15%.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a rapeseed meal and a processing method thereof, and an animal feed containing the rapeseed meal. Background technique [0002] Rapeseed is one of the main oil crops in the world and also one of the main crops in my country. my country's rapeseed production ranks first in the world, with an annual output of more than 5 million tons, and 3.5 million tons of rapeseed meal after oil extraction. Rapeseed meal is a good protein resource, generally containing 35%-45% protein. The amino acid composition of rapeseed protein is reasonable, which is very close to the model recommended by the Food and Agriculture Organization of the United Nations (FAD) and the World Health Organization (WHO). Its nutritional value It is superior to soybean protein, comparable to casein, and is a promising source of complete protein feed. [0003] The main anti-nutritional and toxic substances in rapeseed m...
