Abstract
Rapeseed dregs is the unconventional protein feed resource of one of aquaculture, and glucosinolate (being called for short sulphur glycosides) content is the bottleneck limiting its extensive use.The present invention utilizes a kind of new feed processing technology---Steam explosion treatment technology, the sulphur glycosides of the overwhelming majority in rapeseed dregs can be removed fast and efficiently.Pretreatment adds water to make rapeseed dregs aquation a period of time; Add pretreatment rapeseed dregs in the feed bin of steam blasting instrument, under specific pressure, process certain hour; The sulphur glycosides of in rapeseed dregs 87.2% can be removed after explosion.Compared with prior art, this technology has the features such as pretreatment is simple, the time is short, efficiency is high, pollution-free, is conducive to carrying out detoxification from rapeseed dregs raw material beginning of production.
Description
Technical field
The invention belongs to feed processing technology, be specifically related to a kind of feed processing technology removing glucosinolate in rapeseed dregs (being called for short sulphur glycosides) content fast.
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 import.China produces dregs of rapeseed cake per year and reaches more than 7,000,000 tons, but obtains 30% of the grouts inadequate resource total amount of efficiency utilization for a long time.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 efficiency utilization key technology research in a deep going way.The crude protein content of rapeseed dregs is higher, and reach about 34% ~ 38%, crude fiber content is higher, reaches about 12% ~ 13%.Poisonous and harmful element in rapeseed dregs is sulphur glucoside mainly, sulphur glucoside itself is nontoxic, its catabolite is isothiocyanates and oxazolidine thione mainly, the disorder of animal Thyroid Gland Swell, thyroxine secretion and liver enlargement can be caused, hepatosis, thus impact is grown and production performance, is even poisoned to death.In addition sulphur glucoside has acid, can reduce the appetite of animal, reduces the nutritive value of rapeseed dregs, thus limits its extensive use.
The method of the detoxification of rapeseed dregs mainly soil buries method, infusion method, alkali lye neutralisation, expanded method and fermentable process.Although these processing methods have certain effect, but virus elimination rate height differs, also exist: after detoxification, the loss of rapeseed dregs nutriment is larger, as caused protein denaturation, solubility reduces, protein digestibility declines, some water miscible nutriments run off, thermo-responsive nutriment is destroyed, mineral element loss etc. because of alkali effect; 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, there is 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 there is excellent species and be difficult to problems such as cultivating, conservation is difficult.This area is in the urgent need to a kind of method overcoming sulphur resources in the quick removal rapeseed dregs of above-mentioned shortcoming.
Summary of the invention
The invention provides the method for glucosinolate content in a kind of quick removal rapeseed dregs, comprise the steps:
(1) in rapeseed dregs, add water, place until the abundant aquation of rapeseed dregs;
(2) steam regulation explosion instrument, after reaching specific steam pressure, by step 1) rapeseed dregs that obtains puts into the feed bin of steam blasting instrument, and dimension pressure 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, obtains virus-free rapeseed meal.
In a preferred embodiment, the amount adding water described in described step (1) is with 20 ~ 40% of described rapeseed dregs weighing scale.More preferably, the amount adding water described in described step (1) is with 25 ~ 30% of described rapeseed dregs weighing scale.
In a preferred embodiment, the time of placing described in described step (1) is 1 ~ 20 hour.More preferably, the time of 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 explosion treatment time in described step (2) is 15 seconds ~ 120 seconds.More preferably, the Steam explosion treatment time in described step (2) is 30 ~ 90 seconds.Especially preferably, the Steam explosion treatment time in described step (2) is 60 ~ 90 seconds.
In a preferred embodiment, the present invention can remove the sulphur glycosides of in rapeseed dregs 74%.More preferably, the sulphur glycosides of in rapeseed dregs 87.2% can be removed.
The present invention has the features such as pretreatment is simple, the time is short, efficiency is high, pollution-free, overcomes that virus elimination rate in prior art is low, the processing time is long, requires high, to reduce feed palatability, excellent species conservation difficulty, detoxification high in cost of production problem to the anticorrosive of equipment.Specifically, the present invention only needs the humidity adjusting rapeseed dregs with water, 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 to control fermentation temperature, Steam explosion treatment equipment 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 the sulphur glycosides of in rapeseed dregs 87.2%, comprehensive benefit is the highest.
Accompanying drawing explanation
Fig. 1 provides the result of the test of embodiment 1.
Detailed description of the invention
In order to better the present invention is described, 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 feed bin, dimension pressure a period of time, carry out explosion; Collect the sample after explosion treatment, dry, pulverize, namely complete the detoxification treatment of rapeseed dregs.Fig. 1 gives the result of 6 process, 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 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; NY/T1582-2007 method is adopted to detect the content of sulphur glycosides in virus-free rapeseed meal after process.Result shows, the inventive method can remove the sulphur resources of in rapeseed dregs 87.2%, and detoxification efficiency is obvious.
