Description
Technical field
The present invention relates to Testa Tritici and manufacture field, reduce Testa Tritici vomitoxin particularly to a kind of extruding puffing
Method.
Background technology
Vomitoxin (vomitoxin), also known as deoxynivalenol (DON), chemistry entitled 3 α, 7 α, 15 1
Trihydroxy grass Fusariumsp-9-alkene-8-ketone, belongs to trichothecene, owing to it can cause the vomiting of pig to gain the name, right
Human body has certain damaging effect.The pollution of vomitoxin is widely present in world community, China, Japan, the U.S., the former Soviet Union, south
Non-grade is all found.Vomitoxin mainly pollutes the cereal crops such as Semen Tritici aestivi, Fructus Hordei Vulgaris, Herba bromi japonici, Semen Maydis, also pollutes cereal product, as
Bread, cookies, wheat dessert etc..It addition, be all found vomitoxin residual in the milk, egg of animal.Vomitoxin is for grain
The pollution situation of frumentum is relevant with factors such as toxigenic bacterium strain, temperature, humidity, ventilation, sunshines.Wheat scab is mainly distributed on tide
Wet Temperate Region in China, most of China area is the most exactly in this area, and it is more serious former that this is that China's vomitoxin pollutes
One of because of, in the rainy time, the pollution situation of vomitoxin is even more serious, and gibberella saubinetii poisoning is also that China is topmost very
One of bacterium property alimentary toxicosis, this most increasingly causes the attention of people.
For Semen Tritici aestivi, its vomitoxin is primarily present in Testa Tritici, and Testa Tritici is the pair after wheat processing
Product.Mostly being used as feedstuff and brewage adjuvant, economic use value is the highest.Containing a large amount of available physiologically active meals in wheat bran
Food fiber, cellulose therein and hemicellulose are the dietary fiber sources of high-quality.Due to vomitoxin in food processing non-
Often stable, fry temperature 140 DEG C, boil all destroy less.If directly Testa Tritici being processed as food as base material, have
There may be vomitoxin excessive problem.
The existing research about Testa Tritici is concentrated mainly on the extraction of wheat edible fiber and purification, the changing of dietary fiber
The extraction aspect of effective ingredient in property, dietary fiber, primarily focuses on the survey of vomitoxin about the research of Semen Tritici aestivi vomitoxin
Determine aspect, and the method about the vomitoxin removing Testa Tritici is the most fewer.
Summary of the invention
The technical problem to be solved is to provide a kind of method reducing Testa Tritici vomitoxin.Require the party
Method can effectively reduce vomitoxin contained in Testa Tritici, and operating procedure is simple.
For solving above-mentioned technical problem, the present invention provides a kind of method that extruding puffing reduces Testa Tritici vomitoxin,
Comprise the following steps:
(1) Testa Tritici is mixed with water with the ratio that weight ratio is 13 3.5 of water according to Testa Tritici, then by adding
It is 10 12 that alkaline matter adjusts pH value, soaks filter pressing after 20 30min；
(2) by the drying materials of step (1) gained, the Testa Tritici after drying is obtained；
(3) Testa Tritici after step (2) gained being dried and starch complex, mix homogeneously；
(4) Testa Tritici of step (3) gained and starch mixture are placed in extruder, carry out expanded detoxification treatment,
Obtain Testa Tritici and starch swelling thing, then Testa Tritici and starch swelling thing are placed in pulverizer pulverizing, obtain Semen Tritici aestivi after detoxification
Wheat bran puffing powder；
(5) it is that the ratio of 1 1.8 2.3 is by Testa Tritici puffing powder and water after detoxification in Testa Tritici puffing powder and water weight ratio
Mix homogeneously, add acetic acid, regulation pH value to 7 7.5, filter pressing；
(6) the filter pressing thing of step (5) is dried, obtain Testa Tritici corium farinosum.
For the sake of concise description problem, a kind of extruding puffing of the present invention reduce Testa Tritici vomitoxin method with
Under all be referred to as this method.
First Testa Tritici is soaked in being placed in aqueous alkali by this method, makes Testa Tritici fully absorb aqueous alkali.After filtration, then
The Testa Tritici of alkalescence is compounded by a certain percentage with starch after drying, enters in extruder and carry out expanded detoxification treatment,
Pulverize again and neutralize except alkali, drying prepare Testa Tritici corium farinosum.The Testa Tritici corium farinosum dietary fiber content that this method prepares is high, vomiting poison
Element amount is low, can meet Semen Tritici aestivi in " mycotoxin limitation in national food safety standard food " (GB 2,761 2011) food
The vomitoxin limit index of powder is 1000(μ g/kg) relevant criterion, Testa Tritici corium farinosum prepared by this method can be as interpolation
Thing, with the various various food rich in dietary fiber of other foodstuff base material hybrid process, range of application is the most wide.
As the optimization of this method, described alkaline matter is sodium hydroxide.
There is the lactone ring of double bond composition in vomitoxin structure, this lactone ring can be beaten under alkalescence and hot conditions
Broken, thus destroy vomitoxin to reach detoxification purpose.It is applied to food in view of the Testa Tritici corium farinosum after processing, and destroys interior
The pH value that ester ring requires is higher, as use alkalescence material will certainly be because the addition too much phenomenon that causes exceeding standard, therefore, we
The alkaline matter that method considers is the strong basicity food additive that country allows to use.
Owing to the Testa Tritici puffing powder after detoxification is alkalescence, in Testa Tritici corium farinosum, there is residual, according to China's food additive
Adding agent administrative provisions, sodium hydroxide can be applicable in varieties of food items as food processing aid, but completion of processing need to be adjusted by acidity
Joint agent is neutralized removal.It addition, as base material when processing other food, the Testa Tritici corium farinosum of alkalescence can affect the product of food
Matter, therefore, uses acetic acid to be neutralized to neutral range as acidity regulator, and pH value is neutral to alkalescence 7 7.5,
Sodium hydroxide is also neutralized completely, has substantially no effect on Testa Tritici puffing powder and processes other food for base material.
As the optimization of this method, the Testa Tritici described in step (3) is 2.6 41 with the weight ratio of starch complex.
Owing to the content of starch of Testa Tritici is relatively low, only 10% 15%, and starch is expanded basis, forms sediment in material
When powder content is less than 30%, extrusion difficulty, expansion effect is poor, and this method, according to the content of starch of Testa Tritici, is ensureing smooth squeezing
Go out expanded on the basis of, reduce the ratio of starch as far as possible, increase the ratio of Testa Tritici.
As the optimization of this method, the condition of step (4) described bulking machine detoxification treatment is: screw speed is 10 20r/
Min, extruding puffing temperature are 160 180 DEG C.
The water content of the Testa Tritici after described step (2) drying is 30 35%.
Testa Tritici extruder to be entered after processing due to alkali processes, and during extruding puffing, the water content of material is direct
Affecting expansion effect, follow-up screw speed is set to 10 20r/min by this method, and speed is relatively slow, and Testa Tritici can be made swollen
Change machine stops the longer time, therefore, water content is had strict demand: moisture is too high, make material excessively lubricate, reduce
Extruding force between material and screw rod, is unfavorable for the destruction of vomitoxin；Moisture is low, it is difficult to make material be completely dispersed molten
Melt, cause material to cause vomitoxin to destroy inequality the sleeve inner of bulking machine is uneven.
The temperature of extruding puffing is the highest, and in bulking machine, residence time is the longest, and it is the most that vomitoxin is destroyed, too high
Temperature and long-time heating can cause the polysaccharose substance generation caramelizations such as starch, generate further another kind of nuisance
Matter furfural, this method is through test of many times and detection, and under the process conditions of this method, material there is no caramelization and occurs,
Vomitoxin is destroyed to far below 1000(μ g/kg) relevant criterion.
As the further optimization of this method, the Testa Tritici corium farinosum that described step (6) filter pressing thing obtains after drying aqueous
Amount is 11 13%.
Owing to the moisture of general flour is 11 13%, it is considered to the keeping quality of Testa Tritici corium farinosum, when moisture is 11 13%,
The shelf-life of Testa Tritici corium farinosum can reach the shelf-life of flour substantially, it is simple to preserves.
This method has the advantage that
(1) the Testa Tritici corium farinosum dietary fiber content prepared is high, and vomitoxin amount is low, meets " national food safety standard food
Middle mycotoxin is limited the quantity " in (GB 2,761 2011) food the vomitoxin limit index of wheat flour be 1000(μ g/kg)
Relevant criterion.
(2) the Testa Tritici corium farinosum prepared can be various rich in meals with other foodstuff base material hybrid process various as additive
The food of food fiber, range of application is the most wide.
(3) operating procedure is simple, easily manipulates.
