Abstract
The present invention relates to a method for producing food additives using flax stalks or flax cakes and flax seeds as raw materials. The method of the present invention is characterized in that an acidic water solution or an organic solvent is used for soaking to obtain flax seed adhesive. The present invention has the advantages of simple technology, reliable method, low production cost, no pollution and high quality of obtained products, and is a new approach of flax development.
Description
The present invention relates to plant stem, degreasing plant seed and plant seed are the method for raw material production foodstuff additive.
The present invention adopts flax cane or linseed oil processing and fabricating foodstuff additive.Flax is a kind of widely distributed oilseed plant, and about 630,000 public affairs of its cultivated area are inclined, and are rich in abundant grease, albumen and colloid in its seed, also contain the colloid about 10% in cane.Flax glue is a kind of good whole food thickening material, and its major ingredient is L-rhamnosyl, D-wood sugar, D-semi-lactosi and L-arabinose, and flax glue is of many uses in food, medicine, day chemical industry.
Existing method such as the Chinese patent ZL91110846.7 that produces natural flax glue, Japanese Patent JP55165902 are that employing is a raw material with the linseed oil, and the water as solvent glue makes solid-state dried glue through concentrate drying.Its weak point is to carry in the glue process for keeping linseed oil excellent, thereby glue extraction concentration is lower, glue concentrates difficulty, productive rate is on the low side, the drying of linseed oil also exists difficulty big behind the glue to carrying, the problem that energy consumption is high, gained colloid rehydration swelling property is little behind the glue concentrate drying, in the production implementation process significant limitation is arranged.
Task of the present invention is to propose a kind of new method of producing flax glue, this method is raw materials used to be flax cane, degreasing flax grouts or linseed oil, the flax glue of producing in this way, not only desirable exquisiteness of appearance luster, and the performance of product and yield all are significantly increased.
The present invention adopts following two kinds of schemes.
Scheme one: the cleaning of flax cane is ground into the long material base of 0.2～0.5mm, after (or with flax grouts that adopt the low temperature method for cold pressing degreasing) soaks 10～30 minutes with sour water earlier, add the conditioning agent temperature reaction, insulation is 0.5～1 hour when treating that temperature reaches 80～90 ℃, at last with the resultant of reaction extruding, filter, concentrate, drying makes pure flax glue.
Scheme two: flax cane is crushed to 1-2mm (or using linseed oil), use the tart polar organic solvent, after soaking 10～60 minutes below the boiling point, add conditioning agent and be incubated 20～30 minutes again, in whole process, adopt 500 rev/mins emery wheel agitator constantly to stir, make the glue shell fall into solvent, form suspension liquid, with reactant filtration, separation, dry, pulverizing, make pure flax glue at last.
The present invention adopts following technical process:
1. flax cane → cleaning impurity elimination → pulverizing segment (or using flax dregs of rice) → sour water stirring and leaching → conditioning agent lixiviate → press filtration → glue spraying concentration (or the rotation tubulation concentrates) → air-stream spraying drying → finished product.(shown in Figure of description 1)
2. flax cane → cleaning impurity elimination → pulverizing segment (or linseed oil) → organic solvent cleaning → acid organic solvent emery wheel stirring and leaching → adding conditioning agent continues stirring and leaching → filtrate distillation precipitation → dry rubber powder → pulverizing → finished product.(shown in Figure of description 2)
In technology 1, used flax grouts refer to and adopt low-temperature defatted technology, make linseed oil heating temperature in skimming processes be lower than 80 ℃, adopt low-temperature cold-squeezing technology simple, and cost is low.Flax cane or flax grouts are carried in the glue process vat liquor for acid, available organic acid, as citric acid, acetate, oxysuccinic acid, oxalic acid etc., also available mineral acid example hydrochloric acid, sulfuric acid, phosphoric acid, sulfurous acid, sulphite, hypochlorous acid, hypochlorite or the compound preparation between them, adopt hydrogen peroxide and hypochlorous acid compound preparation, effective, cost is low, and usage quantity is 0.5～5% of a raw material, and described flax glue concentrates and adopts spraying to concentrate or rotation tubulation vacuum concentration, described dry air-flow or the spraying drying of adopting, the material temperature out is lower than 80 ℃.
Used polar organic solvent among technology 2 can be that boiling points such as alcohols or acetone are lower than 90 ℃ polar organic solvent or its mixed solvent; The acid of transferring PH can be that organic acid or mineral acid use hypochlorous acid, the effect of hydrochloric acid or phosphoric acid is comparatively desirable, it is 1～5 that acidity preferably is transferred to PH, conditioning agent can be a hypochlorous acid, sulfurous acid, hydrogen peroxide, hypochlorite, sulphite or the compound preparation between them, adopt hydrogen peroxide and hypochlorous acid compound preparation effect better, usage quantity is 1～10% of a raw material: in whole leaching process, temperature of reaction is below 80 ℃, raw material flax cane or linseed oil epidermis become tawny by Vandyke brown, seed is excellent, the stirring suction strainer separates, sieve diameter 0.1～1mm, filtrate is through precipitation, behind membrane filtration or the distillation precipitation, vacuum-drying is pulverized and is got finished product, and the finished product yield is near content value; Linseed oil after coming unstuck can continue processing system oil through precipitation, and the numb cake in oil expression back can continue to produce high protein feed.
Major advantage of the present invention: scheme one is carried the concentration height of sol solution, and product yield height reduces the low operation of steam output cost with short production cycle and is easy to control.Scheme two reduces glue greatly and concentrates and drying difficulty, and the product yield is near gelationus content value on cane or the seed, and the performance of product is greatly increased, and is applicable to the requirement of industrialized production.
Below in conjunction with example the present invention is described:
Example 1
Get flax cane 100kg (or flax dregs of rice 100kg of the cold press degreasing of learning from else's experience) that is crushed to 0.2～0.5mm, add the 500kg deionized water, after transferring PH to be 3 with hypochlorous acid, stir to soak and to add hydrogen peroxide 10000ml in 10 minutes and stir and be warming up to 50 minutes press filtrations of 85 ℃ of insulations and separate glue and impurity, it is 6% that glue is concentrated into gelatin concentration with rotation tubulation thickener, is drying to obtain 11kg flax glue (is that raw material can get flax glue 15kg with flax dregs of rice) with the pneumatic spray drying device.
Example 2
Get the falx straw 100kg (or linseed oil 100kg) that cuts off long 1-2mm and added ethanol 100kg stirring and washing 10 minutes, get rid of waste liquid, adding ethanol 200kg again is 3 with hypochlorous acid or phosphoric acid accent PH, adopts 500 rev/mins emery wheel agitator warming while stirring to 75 ℃ stirring and leaching to add conditioning agent hydrogen peroxide 2000ml after 50 minutes.The continuation stirring and leaching is after 30 minutes, and the stirring suction strainer separates, and the filtrate decompression distillation is removed ethanol postprecipitation vacuum-drying pulverizing and got finished product 11kg (is that raw material can get finished product 17kg with the linseed oil).Each step washing and filtrate can recycle after distillation.
