Abstract
From the corn natural carotene extracting technology is a kind of foods processing technique, and it extracts from the byproduct protein powder of W-Gum production.Because of the carotene in the corn nearly all is contained in the protein powder.Protein powder is dried, ground.Put into abstraction pool after sieving, and put into extraction liquid simultaneously, stir, in the pond, keep constant temperature and regular hour with agitator.Take out leach liquor then and insert in the distiller, can obtain natural Beta-carotene after the extraction liquid volatilization.Extraction liquid can be recycled after collection and treatment.This technology investment is few, technology is easy, has improved the added value of corn processed.Effectively utilize grain resource.
Description
The present invention is a kind of foods processing technique.
Natural carotene is a kind of fine coloring agent, is widely used in the painted of food, medicine and makeup.Synthetic colour is more because of the effect of paying to human body limits, and natural carotene not only can be used as tinting material, and it can be converted into vitamin A in human body, improves the resistance against diseases of human body etc., and according to the latest news, it also has significant anti-cancer effect.Natural carotene is present in the yellow corn seed, at present directly the technology of extracting in the corn it exist facility investment huge, the raw material treatment capacity is big, chemical reagent unit consumption height, materials abstraction aftertreatment complexity, so large-scale industry production is non-remunerative.
The objective of the invention is to develop corn comprehensive utilization deep processed product, improve the added value of corn processed.Efficiently utilize grain resource, make that the natural carotene extraction process is simple, less investment, the raw material treatment capacity is little, the chemical reagent unit consumption is low, thereby, the tooling cost of natural carotene reduced greatly.
As everyone knows, the production of W-Gum is by a series of Physical Processing.Each composition of corn kernel is separated, take off technological processs such as embryo, screening as corn cleaning, corn soaking, corn, produce W-Gum, and the product corn steep liquor of paying, germ oil, germ cake, protein powder, Semen Maydis grit etc. are arranged, these all are useful products, comprising protein powder.And carotene nearly all is included in the protein powder of corn.
The present invention is exactly the Technology of paying extraction carotene the product protein powder of producing from W-Gum, and the flow process of its production technique is seen accompanying drawing.Pair general water content of product protein powder of W-Gum processing is higher, does not meet carotene processing requirement, so at first carry out drying treatment, grind then, sieve again, afterwards protein powder is put into abstraction pool, and put into extraction liquid simultaneously and extract immersion.Extraction liquid of putting into and protein powder are 3: 1 by weight.Extraction liquid and protein powder keep certain temperature and certain extraction time in the pond, simultaneously in the abstraction pool agitator is housed, and the stirring that will not stop by fixed rotating speed in extraction process.After time arrived, the taking-up leach liquor was also put into distiller and is carried out normal pressure or underpressure distillation.Like this, extraction liquid evaporation, the interior last natural carotene that is needs of distiller.The extraction liquid vacuum available extraction method of evaporating during distillation is extracted in the extraction liquid container.Can be recycled through after certain processing.The extraction liquid that uses in extraction process also is very important, and its composition is that ethanol and normal hexane mix by a certain percentage.Protein powder behind the extraction natural carotene passes through drying treatment again, does not still lose original use value.
Adopting this technology to extract carotene can only increase some utility appliance on the basis that produces W-Gum equipment, just can go into operation.This technology is compared with directly extracting carotene in the yellow corn, and less investment, technology are easy again, and the raw material treatment capacity is little, and the chemical reagent unit consumption is few, and materials abstraction is handled simple, has importantly increased the added value of grain processing.The natural carotene content that obtains with this technology is up to more than 50%, and the carotene extraction rate reached in the corn is more than 90%, and it is compared with the carotene of chemosynthesis, has good water-solublely, as tinting material, can bring about a wholesome effect to human body.
In concrete enforcement, in drying process, can utilize Vacuumdrier or pneumatic drier etc. with protein powder, its water content is dried to 6-8% be advisable, use the 60-80 mesh sieve when sieving.In extraction process, the extraction time kept 4-6 hour, and temperature remains on 40-50 ℃ and is advisable, and the rotating speed of agitator is best with 300-400 rev/min.The extraction liquid that uses is with chemical pure dehydrated alcohol and chemical pure hexane, converts system by (volume ratio) 1: 1.5-2 and forms, and more than be the top condition that guarantees to extract natural carotene.
Claims (2)
1, extracts natural carotene technology in the corn and belong to foods processing technique, it extracts from the by-product protein powder of W-Gum production, it is characterized in that: protein powder is through after drying, pulverizing, sieve, extract immersion, and put into extraction liquid simultaneously, protein powder and extraction liquid keep certain temperature and time in abstraction pool, and stir with agitator simultaneously, take out leach liquor then and put into distiller, can obtain natural carotene the extraction liquid evaporation.
2, Technology according to claim 1 is characterized in that: used extraction liquid is to mix with ethanol and normal hexane, and ethanol is that chemical pure dehydrated alcohol, normal hexane are also used chemical pure, and its ratio is to be 1 by volume: 1.5-2.
