Abstract
The invention discloses an integrated extracting technology of oil and protein powder from corn pangen, which comprises the following steps: 1) extracting pangen slag and immersed oil solution from corn pangen through alcohol; separating immersed oil solution from oil; 2) dissolving pangen slag through alkaline solution to obtain insoluble slag and alkaline protein liquid; sedimenting protein in the alkaline protein liquid to obtain the protein powder.
Description
Technical field
The present invention relates to a kind of from maize germ integrate extraction method for oil and albumen powder technology.
Background technology
Maize germ oil contains more unrighted acid, but also contains than more vitamin E of other edible oils and phytosterol, so be internationally recognized healthy oil.The extracting method of tradition maize germ oil is milling process, lixiviation process, perhaps presses earlier the method for afterwards soaking.No matter but adopt which kind of method, in order to improve the oil productivity of plumule, all plumule is carried out high-temperature process more than 100 ℃, purpose be to destroy plumule eucaryotic cell structure, make the protein coagulating sex change, be beneficial to obtain more oil.Even in plumule, mix 20% maize peel, with the mediation oil circuit.Below only considered the recovery of the oil of the 35%-40% in the plumule, reckoning without the protein that also contains in the plumule about 20% can't recycle.Because germ protein is in above-mentioned system oil process, sex change can only be made cheap feed and sell.Present a large amount of corn protein powders of being produced of cornstarch manufacturing enterprise are not because of wherein globulin and albumin content are full price albumen less than total amount 8%, so can only do cheap protein feed use.And globulin and albumin content reach more than 60% of total content in the corn germ protein, and its contained human body must amino acid, meet the regulation of WHO's full price albumen.Maize germ oil is per ton in the world is 700 dollars, and corn embryo albumen powder is per ton to be more than 1400 dollars, and only about 300 dollars of conventional corn albumen powders.So study when from plumule, extracting embryo oil, consider from plumule, to reclaim the germ protein powder, with the comprehensive utilization ratio of raising resource, and be that society develops the new protein resource of nutrient health more, have practical significance.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, provide a kind of from maize germ integrate extraction method for oil and albumen powder technology, to improve the comprehensive utilization benefit of maize germ.
Technical scheme of the present invention is: a kind of from maize germ integrate extraction method for oil and albumen powder technology, comprise the following steps:
1) obtain the plumule slag and leach oil solution with the alcoholic extract maize germ, the temperature of alcoholic extract is 45-60 ℃, leaches oil solution and separates oilyly;
2) dissolve said plumule slag with alkali and obtain alkali insoluble slag and the molten protein liquid of alkali, the protein in the molten protein liquid of precipitation alkali gets albumen powder.
The invention has the advantages that technology is simple, improve the economic benefit of maize germ comprehensive utilization greatly.
Describe technical process of the present invention in detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
At first carry out pretreatment of raw material: the wet corn plumule contains protein 15-20% (all being weight percentage, down together), fatty 35-40% usually.Under 10-50 ℃ of condition, the wet corn plumule is dried to moisture 5-10%.Be crushed to more than 40 orders after the election contest peeling.
Alcoholic extract: in raw material: the ratio of alcohol=1: 2-3 adds alcohol, be not more than under 60 ℃ the condition extraction in temperature 3-5 hour, obtain the plumule slag and leach oil solution (alcohol and oily mixed solution), leach oil solution, boil off alcohol with the cold boiler evaporation.Under the residue is embryo oil (crude oil).Extract the remaining plumule slag in oily back, be about the 85-90% of plumule weight.The dissolution rate of extraction temperature influence oil, the general too high meeting of temperature causes protein coagulating, and the stripping quantity that temperature is crossed low then oil reduces.The preferred 45-55 of extraction temperature ℃
Protein Extraction: with the plumule slag in the plumule slag: the ratio of water=1: 10-14 adds water, is incubated 35-45 ℃, slowly adds alkali lye, makes PH reach 8-9.5.Filter then, get molten protein liquid of alkali and alkali insoluble slag, the molten protein liquid of alkali is splashed into acid solution, make albumen precipitation, filter when PH reaches 4-4.5, filter cake is an albumen powder.Usually the rate of recovery of albumen powder is 14-17%.The preferred NaOH solution of alkali lye, the preferred HCl solution of acid solution.
Usually the oil that also contains small amount of residual in the alkali insoluble slag can continue it is extracted with alcohol, and method is the same.
Embodiment 1
Moisture 5% plumule of 40 orders 500 grams add 1330 milliliter of 95% alcohol, and 50 ℃ of temperature extracted 5 hours, got the leaching mixed liquor 790ml of spirituosity and embryo oil.Leach mixed liquor with the cold boiler evaporation and slough alcohol, obtaining the crude oil amount is 50 grams.The rate of recovery of oil is 10% in the plumule, and the remaining quantity of slag of doing is about 430 grams.It is 1: 12 that the dried slag of 10 grams is added water to solid-to-liquid ratio, splashes into NaOH.Be incubated 40 ℃, to PH=9.Filter the back, gets the molten protein liquid 112.5ml of alkali, and the molten protein liquid of alkali is splashed into HCL, and protein is precipitated, when PH reached 4.5, the heavy liquid of acid was 112 milliliters, gets the albumen powder filter cake after filtration, with the filter cake low temperature drying, get albumen powder 1.85 grams, the recovery of protein rate is 17.3% in the plumule.
Embodiment 2
Plumule 500 grams of 40 orders moisture 5%, 1330 milliliters of the alcohol of adding 95%, 55 ℃ of temperature extracted 4 hours, got the leaching oil mixed liquor 820ml of spirituosity and embryo oil.Leach oily mixed liquor with the cold boiler evaporation and slough alcohol, obtaining the crude oil amount is 47 grams.The rate of recovery of oil is 9.4% in the plumule, and remaining dried plumule slag is about 420 grams.10 gram plumule slags are added water to the plumule slag: water=1: 12, be incubated 45 ℃, splash into NaOH to PH=8.5.Filter the back, gets the molten protein liquid 119.5ml of alkali, and the molten protein liquid of alkali is splashed into HCL, and protein is precipitated, when PH reached 4, the heavy liquid of acid was 113 milliliters, gets the albumen powder filter cake after filtration, with the filter cake low temperature drying, get albumen powder 1.74 grams, the recovery of protein rate is 14.76% in the plumule.
Embodiment 3
Plumule 500 grams of 40 orders moisture 5% add 1330 milliliters of 95% alcohol, and 55 ℃ of temperature extracted 4 hours, get the leaching oil mixed liquor 800ml of spirituosity and embryo oil.Slough alcohol with the cold boiler evaporation, obtaining the crude oil amount is 48 grams.The rate of recovery of oil is 9.6% in the plumule, and the remaining plumule quantity of slag of doing is about 455 grams.It is 1: 12 that the dried plumule slag of 10 grams is added water to solid-to-liquid ratio, splashes into NaOH.Insulation 40C is to PH=9.5.Filter the back, gets the molten protein liquid 118ml of alkali, and the molten protein liquid of alkali is splashed into HCL, and protein is precipitated, when PH reached 3.5, the heavy liquid of acid was 118 milliliters, gets the albumen powder filter cake after filtration, with the filter cake low temperature drying, get albumen powder 1.77 grams, the rate of recovery 16.1% of albumen powder in the plumule.
With also obtaining the alkali insoluble slag behind the alkali dissolving plumule slag, in the alkali insoluble slag oil residues is arranged still generally speaking in the various embodiments described above, can continue it is extracted with alcohol, method be with maize germ is extracted.For example get alkali insoluble slag 100 grams that the various embodiments described above obtain, add 266 ml ethanols, temperature is 50 ℃, and extraction in 4 hours boils off alcohol then, obtains crude oil 9 grams.
