Abstract
A kind of extracting method that contains the natural beta-carotin of zeaxanthin as raw materials for food industry.The carotene of synthetic, inevitably contain organic substance, and natural Beta-carotene is to extract from vegetables such as tomato, red pepper or saponification reaction extraction from the raw material that contains carotene with organic solvent ether or chloroform, so raw material sources are few, product cost height, present method are to use ethanol through extraction-separation and Extraction with a large amount of byproduct protein powders that W-Gum is produced, and cost is low, raw material sources are abundant, and no waste.Its byproduct is to contain the carotene of zeaxanthin and the mixture of multiple amino acids.Residue is a feed.
Description
The invention belongs to the extracting method of raw materials for food industry
At present domestic commercially available β-Hu Luobusu is very few, most of usefulness all are synthetic product of import, expend foreign exchange, cost is higher, synthetic product also are not so good as natural quality height, and can have micro-organic substance in building-up process.According to the pertinent data introduction, the synthetic β-Hu Luobusu starts from 1954.1962 and 1964, successively synthesized apo-8-carotenal again and be used for food dyeing.The report that extracts carotene with saponification reaction (KOH) is also arranged in addition from the raw material that contains carotene, also have from vegetables such as tomato, red pepper report with ether or chloroform extraction carotene.It is unfavorable to health that these methods can be introduced organic solvent first, and second raw material sources are less, can not extract in a large number, and cost is higher.
The objective of the invention is to utilize conventional innoxious solvent ethanol from a large amount of Zein powders, to extract the β-Hu Luobusu that contains natural pigment on a large scale, with edible more conveniently.
β-Hu Luobusu is an indispensable nutrient substance in the human body, and it is converted into vitamin A and is absorbed in human body, and for the prevention eye illness, vision protection is safeguarded the physiological function of human body epithelium, promotes children's normal development all to play an important role.Can be widely used as foodstuff additive and nutrient substance.For this reason, we have proposed the method that a kind of extraction contains the natural beta-carotin of zeaxanthin, it is characterized in that ethanol is the extraction-concentrated-centrifuging of solvent.Extraction step in the present invention is:
1. get a certain amount of protein powder and add 1-3 ethanol doubly, fully stir, static to solid-liquid separation after ethanol and protein powder fully stir, the taking-up upper layer of extraction liquid places concentration tank.
2. centrifugation, solid residue dries, and packing used as fodder, its major ingredient are starch and a small amount of protein.
3. extraction liquid and centrifugate concentrate distillation in matrass, the etoh solvent that distills out returns and remakes extraction agent usefulness, when extremely being left 20% left and right sides, solution has become the thickness state, this dope is put into the whizzer centrifugation, can obtain this moment containing the β-Hu Luobusu oil of zeaxanthin and containing β-Hu Luobusu and multiple amino acids mixture.
Advantage of the present invention is the food configuration that can change China, reduces from external import carotene, changes the situation of the rarer carotene supply in market.Original only large quantities of Zein powders of used as fodder are turned waste into wealth, improve utilization ratio of raw materials and value, and can export and gain foreign exchange.And the technology of extracting is simple, and raw material sources are abundant, and product is nontoxic, pays a product and be again seed amino acid feed more than the needed by human body, therefore, does not have refuse.
Technical process of the present invention is as figure.
The present invention can extract about 5 kilograms of carotin oils that contain 1.0-1.2mg/ μ l from the product-be paid of processing one ton of W-Gum gained the 100kg protein powder, can obtain content simultaneously is about 0 kilogram of 50-60% amino acid/11.Wherein: asparagus fern amino acid 3.8-4.0% Threonine 1-1.6%, Serine 2-2.4%, L-glutamic acid 16.1-18.0%, glycine 0.8-0.9%, L-Ala 7.5-7.9%, Gelucystine 0.6-0.7%, propylhomoserin 5.5-6.0%, methionine(Met) 0.5-0.6%, leucine 14.1-15.0%, tyrosine 3.0-3.10%, phenylalanine 5.0-5.2%, Methionin 0.12-0.14%, ammonia 2.3-2.5%, Histidine 0.7-0.8%, arginine 1.0-1.2, proline(Pro) 5.0-6.9%, different shell propylhomoserin 3.0-3.1%.
In addition: also contain nontoxic natural colouring matter-be luteole in the natural beta-carotin that proposes with the present invention and the amino acid, like this beta carotene oil and amino acid, not only can be used as food additives, can be used for simultaneously the food dyeing such as beverage, cake, candy, thereby can replace artificial synthetic riboflavin.
Claims (1)
- A kind of extracting method that contains the natural beta-carotin of zeaxanthin is characterized in that with ethanol being the extraction-concentrated-centrifuging of solvent.Its concrete extraction step is: get a certain amount of Zein powder, and adding 1-3 ethanol doubly, fully stir, extracting and separating, place extraction liquid, centrifugate concentration tank (or matrass) to be concentrated into 20% o'clock of original volume, again this concentrated solution is placed the whizzer centrifugation, can obtain containing the β-Hu Luobusu of zeaxanthin.
