Flaxseed paste and processing method
Technical field
The invention belongs to the linseed processing technique field, be specifically related to a kind of flaxseed paste, and the processing method of this flaxseed paste.
Background technology
Flax is commonly called as flax, and the oil content of linseed is about 40%, and wherein the content of alpha-linolenic acid is over half.Alpha-linolenic acid belongs to omega-3 polyunsaturated fatty acids, is the aliphatic acid of needed by human.Studies have shown that: alpha-linolenic acid can synthesize EPA and DHA the human body metabolism, alpha-linolenic acid with and metabolite EPA and DHA have the blood fat of reduction and improve the effect that blood platelet solidifies, can prevent the diseases such as cerebral thrombus and miocardial infarction, have the nervous system development of promotion, improve memory and the functions such as retinal reflex ability, prevention senile dementia, pre-anti-cancer and allergy.Since the last century the eighties, omega-3 polyunsaturated fatty acids is acknowledged as human important and health food effective.Therefore, in recent years, linseed becomes one of focus of domestic and international exploitation.
200710061581.X disclose a kind of linseed kernel sauce and production method thereof, be take linseed as primary raw material, after baking, peeling, make flaxseed paste with sesame and/or common grinding of shelled peanut.But, because the technology for Flaxseed peeling and separation was also very unripe at that time, also contain a large amount of wastes of flax in the flaxseed after causing peeling, just inevitably in flaxseed paste, may contain the cyanogenic glycoside composition poisonous to human body.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of flaxseed paste and processing method are provided, to guarantee to provide to the consumer flaxseed paste of edible safety.
Technical scheme of the present invention is as follows:
A kind of flaxseed paste includes the composition of following parts by weight in per 100 weight portion flaxseed pastes:
70-76 part fat, wherein 38-46 part is alpha-linolenic acid;
18-21 part protein;
3-4 part ash content;
0.2-1 part moisture and volatile matter content;
The fineness of this flaxseed paste (by aperture 0.28mm standard copper sieve) is more than 97%; Acid value (take buttermeter) is 0.2-4mgKOH/g; Cyanogenic glycoside must not detect.
The processing method of described flaxseed paste is:
1) selecting ripe good linseed is raw material, and after cleaning, electricity consumption temperature controllable frying pan parch makes the moisture of linseed drop to 4.5-6.5%, naturally cooling;
2) linseed that step 1) is obtained is machined to the mixture of flaxseed and skin with the rubbing Flaxseed peeling, then with linseed kernel skin separation equipment flaxseed and skin are separated, further with the purity of color selector purification flaxseed, obtain skin-containing rate in the benevolence less than 1% flaxseed;
3) with step 2) flaxseed for preparing under 150-280 ℃ of condition frying 20-40 minute, then wear into the sauce body with stone mill;
4) the sauce body obtains the flaxseed paste product through packing, sterilization.
Studies have shown that, cyanogenic glycoside is distributed in the skin of linseed, and ripe good linseed is lower than cyanogenic glycoside content in the ripe poor linseed skin.Flaxseed paste of the present invention selects ripe good linseed as processing raw material, reduced the content of cyanogenic glycoside from the source, adopted simultaneously linseed parch operation, parch is conducive to the decortication of linseed on the one hand, and parch also is the effective ways of degraded cyanogenic glycoside on the other hand.
The present invention is the substantive breakthroughs to existing Flaxseed peeling technology with Flaxseed peeling the level rise skin-containing rate in the flaxseed in 1%.Evidence, only have the rubbing of employing flax seed dehuller, linseed kernel skin separation equipment in conjunction with linseed being peeled and separating, and with further the purify purity of flaxseed of color selector, just can produce very low, the high-quality flaxseed paste raw material of waste of flax content, in raw material the linseed skin is controlled in 1%, this is the measure that ensures flaxseed paste product safety most critical.
Described flaxseed frying has two purposes, is on the one hand to make the remaining further at high temperature degraded of cyanogenic glycoside of possibility in the waste of flax micro-in the raw material, and be the fragrance that increases flaxseed paste on the other hand.
The invention has the beneficial effects as follows.
(1) alpha-linolenic acid content reaches about 40% in the flaxseed paste of the present invention, and branched-chain amino acid proteinoid content reaches about 20%, is very high nutritious flavouring product or functional food of a kind of nutritive value.
(2) flaxseed paste of usefulness the inventive method processing, owing to comprehensively having adopted further the purify processing method of flaxseed purity of rubbing flax seed dehuller, linseed kernel skin separation equipment, color selector, could in the flaxseed paste raw material waste of flax be controlled in 1%, this is the most critical measure that ensures the flaxseed paste product safety.The present invention has also adopted and has selected ripe good linseed to be raw material, linseed is carried out parch and to the further effective measures of the degraded cyanogenic glycoside such as frying under hot conditions of the flaxseed after the decortication, can't check cyanogenic glycoside in the flaxseed paste of finally having guaranteed to produce.
(3) flaxseed paste of the present invention is of many uses, can be used for bread, steamed bun or wheaten food directly edible, also can be used in the numerous food processing, and also the sauce bag in the alternative present instant noodles improves the nutritive value of instant noodles etc., has a extensive future.
(4) for ordinary consumer, organism metabolism generally lacks alpha-linolenic acid, and flaxseed paste of the present invention has increased the approach of the additional alpha-linolenic acid of consumer, has also expanded the deep processing field of linseed.
The specific embodiment
Embodiment 1
