Description
Technical field
The present invention relates to a kind of extruding and puffing technology and remove the method for flax glue in flax dregs of rice, belong to technical field of agricultural product process.
Background technology
Linseed claims flaxseed again, is the seed of flax family (Linaceae) plant flax.World's linseed output increased sharply in nearly ten years, and China has become and is only second to Canadian second-biggest-in-the-world linseed and produces state, and the output of Chinese linseed accounts for 20% of world's total amount.Wherein, linseed oil is rich in about 73% polyunsaturated fatty acid, 18% monounsaturated fatty acids and become the edible oil and fat source of high-quality.Will certainly produce a large amount of degreasing dregs of rice like this, be rich in protein, lignanoid, Soluble Fiber, mineral matter and vitamins and other nutritious components in flax dregs of rice, it is available valuable source, as not recycled, not only cause the wasting of resources, also can be corrupt owing to piling up, cause serious environmental to pollute.In addition, it contains the breach that rich in protein can replenish protein feed on the market well.But,,, and then reduce the trophism of flax dregs of rice as animal feed because of it influences the absorption of nutritional labeling in the feed comprising flax glue owing to there are some ANFs in flax dregs of rice.The existence of flax glue can influence the deep processing of flax dregs of rice equally, and for example, microbial fermentation flax dregs of rice can also just can't carry out for the fermentation of flax dregs of rice fully because the existence of flax glue makes microorganism to grow fully.
The extrusion process technology is that collection mixing, stirring, fragmentation, heating, boiling, sterilization, expanded and moulding etc. are the new and high technology of one, is widely used in food and feed processing industry.In extrusion pressing puffing process, powder or granular material are converted to face dough plasticising, thickness; Boiomacromolecule is after high temperature, high pressure, instantaneous extruding, and destroyed, the secondary bond fission of space structure, peptide bond are loose, and protein molecule rearranges; The biopolymer structure then can be redirected slabbing or filamentary structure, thereby finishes the matter structure reorganization of natural polymer, protein and the devolatilization of harmful substance, more is of value to its value.If the place allows material temperature, pressure discharge suddenly at the extruding die orifice, also can form the puff of porosity and looseness, help digestion and sweat.
According to above-mentioned principle, flax glue is a kind of polysaccharide mixture, reduce by the high temperature of extrusion, the polysaccharide molecular weight that high shear forces can make flax glue, be degraded to the little polysaccharide of monose or molecular weight, show as the viscosity of the water-soluble glue that has reduced flax dregs of rice effectively, reach the purpose of removing flax glue.
Summary of the invention
The purpose of this invention is to provide a kind of extruding and puffing technology and remove the method for flax glue in flax dregs of rice.
Described extrusion is removed the method for flax glue in flax dregs of rice, is that the waste residue flax dregs of rice that produced during with linolein process plants linseed oil are raw material, adopts extruding and puffing technology to remove flax glue in flax dregs of rice, and concrete technology is:
1) with after sheet flax dregs of rice raw material handling impurity elimination, handles or roll with pulverizer, make flax dregs of rice pulverize and be powder by grease pulverizer or feed;
2) in above-mentioned flax dregs of rice powder, add corn flour, and it is sprayed, when spraying, constantly stir, to regulate the mixture moisture content by a water mist spray device;
3) utilize twin-screw extruder that flax dregs of rice are carried out the extrusion processing of coming unstuck then;
4) at last expanded back material is carried out drying processing, after the gained drying expanded sample after testing the flax glue clearance be 52.0～73.2%.
Described flax dregs of rice are high temperature flax dregs of rice or low temperature flax dregs of rice, and moisture content is 6.07%～6.23%, and total polyoses content is 121.59mg/g, and flax glue extract viscosity is 142.0mpas.
Described flax dregs of rice powder size is 20～120 orders.
Described corn flour adding proportion accounts for 5～20% of mixture gross mass.
Described mixture moisture content is 18.8～35.1%.
The described extrusion treatment conditions of coming unstuck are: the extrusion temperature is 80～160 ℃, and screw speed is 60～180 commentaries on classics/min, and rate of feeding is 30～35kg/h.
Described drying is treated to 60～70 ℃ of oven dry or normal temperature dries.
The inventive method is simple and reliable, easy to operate, cost is low, speed is fast, flax glue clearance height.Technology of the present invention is compared with biological degumming method with existing chemistry, has not only improved a clearance of flax glue, and has made the nutrition digestion of flax dregs of rice significantly improve, and has reduced because the waste liquid that chemistry and bioanalysis come unstuck and produced.Realized coming unstuck and maturing process of flax dregs of rice simultaneously, can produce protein feed into a kind of high-quality.
