Abstract
The method for extracting flax gum from flax seed by using wet method includes the following steps: firstly crushing flax seed, separating husk and kernel, screening husk and extracting husk twice by using warm water, mixing extracts, filtering and drying filtrate to obtain the product flax gum, or using warm water to extract the husk once, and using hydrochloric acid and 18 carbon olefine acid mixed solution to extract once, drying the extract to obtain the invented product, or using sanitary alcohol to extract twice, filtering extract mixture, and reduced pressure distilling to obtain the product. Said invention is simple in technological process, easy to operate, and its product is high in yield and purity, and is non-toxic.
Description
The present invention relates to a kind of from flax (being commonly called as flax) wet method extract the method for flax glue, belong to the chemical process technology field.
Flax glue (English name Flaxseed mucilage; Latin is by name: Linseed mucilage), be to use very wide natural (green) vegetable jelly in the industry such as biology, food, pharmacy.Chinese patent CN1072184A discloses and a kind ofly Semen Lini has directly been used water extraction (50 ℃～95 ℃) and add sulfurous acid and citric acid leaches the colloidal method as leaching agent.The shortcoming of aforesaid method is, one, after Semen Lini carried glue by leaching, and also that the Semen Lini of being leached is dry again, go oil expression again, it is this that drying process must the mass consumption energy again again, and this is in suitability for industrialized production and all inadvisable economically; Two, aforesaid method is laboratory test, does not carry out suitability for industrialized production as yet, from its process, is difficult to automatic production, how by unit or manual operation; Three, its drying means may make the glue sex change; Four, lack comprehensive utilization and consider, and only consider to carry glue; What five, add helps leaching agent sulfurous acid, to edible product, especially to being disadvantageous as " green " food, because bring unnecessary inferior sulfate radical into.
The objective of the invention is to study a kind of from the Semen Lini shell wet method extract the method for flax glue, Semen Lini is fully utilized, oleum lini can be used for extracting linolenic acid, Residual oil can be changed a social system industrial lubricant, kernel presses cake and can be used for mixed fodder, make Semen Lini that purposes widely be arranged, improve the added value of Semen Lini.
The wet method from the Semen Lini shell of the present invention's design is extracted the method for flax glue, comprises following each step:
(1) Semen Lini is carried out sub-shell and separate, to obtain the Semen Lini shell with kernel;
(2) from the Semen Lini shell, extract flax glue, the method of extracting is: leached the Semen Lini shells 0.5～2 hour with 30～50 ℃ warm water, to the press filtration of leaching thing, with the slag that leaches, again with 50～85 ℃ warm water leaching 0.5～1 hour, the leaching thing is filtered, with above-mentioned press filtration and filter resulting filtrate 40～60 ℃ dry 2～5 hours down, promptly get the product flax glue;
Or with 30～50 ℃ warm water leaching Semen Lini shell 0.5～2 hour, to the press filtration of leaching thing, with the slag concentration that leaches is 0.1 hydrochloric acid and the leaching of 1M18 carbon enoic acid 0.5～1 hour, making its pH value is 2.5～4, the leaching thing is filtered, filtrate oven dry with above-mentioned press filtration and filtration gained promptly gets the product flax glue;
Or with the Semen Lini shell with alcohol volume ratio be 1: 1～3, concentration is 80% health alcohol, leached the Semen Lini shell 2～4 hours down at 15～25 ℃, the leaching thing is filtered, with the slag that leaches again with volume ratio be 1: 1～3, concentration is 80% health alcohol, 20～45 ℃ of leachings 1～2 hour down, the leaching thing is filtered, above-mentioned secondary filtration liquid is carried out underpressure distillation under 0.5 normal atmosphere, remove contained alcohol wherein, remaining meal is the product flax glue.
The sub-shell of the Semen Lini in the above-mentioned technology and kernel separate any in available rotation mill, conoidal mill or the dull and stereotyped sand table airflow milling, the rotating speed of mill is 50～180 rev/mins, gas velocity is 30～90 liters/minute.
Above-mentioned three kinds of different leaching methods are decided according to the requirement of desired product, and even the low albumin glue of preparation then with the warm water leaching, as if preparing high protein glue, then with hydrochloric acid and the leaching of 18 carbon enoic acid high temperature, if prepare epoxy glue, is then used the alcohol leaching.
Above-mentioned drying process can be used methods such as industrialized normal temperature spraying drying, underpressure distillation and ultra red ray drying with drying means.
Use the method for the extraction flax glue of the present invention's research, the extraction yield of flax glue can be up to 82～95%, the economic value added that Semen Lini is used improves 10～20 times, and the flax glue nontoxicity of extracting, the purity height, can be widely used in biology, food, medicine and other fields, thereby method of the present invention have tangible industrial production and economic benefit.
