Abstract
The rapeseed meal is an unconventional protein feed resource in a breeding industry; and glucosinolate (thioglycoside for short) content is a bottleneck for restricting the wide application of the rapeseed meal. According to the invention, a novel feed processing technology-steam explosion processing technology is employed, and most thioglycoside in the rapeseed meal can be rapidly removed with high efficiency. In a pretreatment step, water is added for hydrating the rapeseed meal for a while; the pretreated rapeseed meal is added to a bunker of a steam explosion instrument, the treatment can be carried out for a certain time under specific pressure intensity; so that 87.2% of thioglycoside in the rapeseed meal can be removed after explosion. Compared with the prior art, the feed processing technology has the characteristics of simple pretreatment, short time, high efficiency and no pollution, and is in favor of detoxifying at a production source of the rapeseed meal raw material.
Description
Technical field
The invention belongs to feed processing technology, be specifically related to a kind of feed processing technology of removing fast glucosinolate in rapeseed dregs (being called for short sulphur glycosides) content.
Background technology
Protein feed resource shortage is the subject matter that China's animal husbandry and feed industrial development face, and supply demand gap is large, needs a large amount of imports.China produces dregs of rapeseed cake per year and reaches more than 7,000,000 tons, but obtains for a long time 30% of the efficient grouts inadequate resource total amount of utilizing.There is very large gap in the actual demand of this situation and feedstuff industry, aquaculture and even agricultural development, therefore, is badly in need of carrying out rapeseed dregs in a deep going way and efficiently utilizes key technology research.The crude protein content of rapeseed dregs is higher, reaches approximately 34%～38%, and crude fiber content is higher, reaches approximately 12%～13%.Poisonous and harmful element in rapeseed dregs is mainly sulphur glucoside, sulphur glucoside itself is nontoxic, its catabolite is mainly isothiocyanates and oxazolidine thione, can cause the enlargement of animal thyroid gland, thyroxine secretion disorder and liver enlargement, hepatosis, thereby impact is grown and production performance, is even poisoned to death.In addition sulphur glucoside has acid, can reduce the appetite of animal, has reduced the nutritive value of rapeseed dregs, thereby limits its extensive use.
The method of the detoxification of rapeseed dregs is mainly that soil buries method, infusion method, alkali lye neutralisation, expanded method and microorganism fermentation process.Although these processing methods have certain effect, but virus elimination rate height differs, exist: after detoxification, the loss of rapeseed dregs nutriment is larger, as causing protein denaturation, solubility reduces, protein digestibility declines, some water miscible nutriments run off, thermo-responsive nutriment is destroyed, mineral element is because of alkali effect loss etc.; Waste liquid after detoxification easily causes water body environment pollution; Operating equipment relative complex, production cost is higher; After detoxification, the palatability of rapeseed dregs is poor, exists detoxifying agent residue problem.Although microbe fermentation method has the advantages such as detoxification efficiency is obvious, fermentation microorganism used therefor must meet the restriction of country to microorganism fodder, and the processing time is long, and exists excellent species and be difficult to the problems such as cultivation, conservation difficulty.This area is in the urgent need to the method for sulphur glycosides content in a kind of quick removal rapeseed dregs that overcomes above-mentioned shortcoming.
Summary of the invention
The method that the invention provides glucosinolate content in a kind of quick removal rapeseed dregs, comprises the steps:
(1) in rapeseed dregs, add water, place until the abundant aquation of rapeseed dregs;
(2) steam regulation explosion instrument, reaches after specific steam pressure, by step 1) rapeseed dregs obtaining puts into the feed bin of steam blasting instrument, and dimension is pressed 30～90 seconds, carries out explosion.
In one embodiment, said method also comprises the steps:
Collect described step 2) sample that obtains, it is dried and pulverization process, obtain virus-free rapeseed meal.
In a preferred embodiment, described in described step (1), adding the amount of water is with 20～40% of described rapeseed dregs weighing scale.More preferably, described in described step (1), adding the amount of water is with 25～30% of described rapeseed dregs weighing scale.
The time of placing described in described step (1) in a preferred embodiment, is 1～20 hour.The time of more preferably, placing described in described step (1) is 8～15 hours.
In a preferred embodiment, the steam pressure in described step (2) is 0.5～3.0MPa.More preferably, the steam pressure in described step (2) is 0.8～2.5MPa.Especially preferably, the steam pressure in described step (2) is 1.0～2.0MPa.
In a preferred embodiment, the steam blasting processing time in described step (2) is 15 seconds～120 seconds.More preferably, the steam blasting processing time in described step (2) is 30～90 seconds.Especially preferably, the steam blasting processing time in described step (2) is 60～90 seconds.
In a preferred embodiment, the present invention can remove in rapeseed dregs 74% sulphur glycosides.More preferably, can remove in rapeseed dregs 87.2% sulphur glycosides.
The present invention has the features such as pretreatment is simple, the time is short, efficiency is high, pollution-free, overcome that in prior art, virus elimination rate is low, the processing time long, equipment anticorrosive required to high, to reduce feed palatability, excellent species conservation difficulty, detoxification high in cost of production problem.Particularly, the present invention only needs water to adjust the humidity of rapeseed dregs, carry out the hydration process of some hours in room temperature, do not exist and pollute and corrosion, do not affect the palatability of feed, do not need controlled fermentation temperature, steam blasting treatment facility needs disposable infusion of financial resources, and energy consumption only needs water, electricity, liquefied gas, only needs the processing time of about 1 minute, can remove in rapeseed dregs 87.2% sulphur glycosides, comprehensive benefit is the highest.
Accompanying drawing explanation
Fig. 1 provides the result of the test of embodiment 1.
The specific embodiment
For the present invention is described better, be convenient to understand technical scheme of the present invention, typical but non-limiting embodiment of the present invention is as follows:
Embodiment
In rapeseed dregs, add water to fully wetting, open QBS-80B steam blasting instrument, steam pressure is adjusted to required vapor pressure, wet-mixing rapeseed dregs is added to feed bin, dimension is pressed a period of time, carries out explosion; Collect the sample after explosion treatment, dry, pulverize, complete the detoxification treatment of rapeseed dregs.Fig. 1 has provided the result of 6 processing, and wherein ratio of water to material (weight ratio of water and rapeseed dregs) is followed successively by 10%, 20%, 25%, 30%, 40%; Hydration time is for being followed successively by 4,6,8,10,12,15 hours; Process that pressure is followed successively by 0.8,1.0,1.5,1.8,2.0,2.5MPa; The dimension pressure time is followed successively by 15,30,60,90,120 seconds; After processing, adopt NY/T1582-2007 method to detect the content of sulphur glycosides in virus-free rapeseed meal.Result shows, the inventive method can be removed in rapeseed dregs 87.2% sulphur glycosides content, and detoxification efficiency is obvious.
