Abstract

The invention provides the aqua one-step method separation and extraction technology of sunflower seed oil protein; the main process comprises the following steps: a sunflower seed is pre-treated by removing husk and knocking out the kernel, and then soaked in water of 30 DEG C to 80 DEG C by the ratio of the kernel to the water of 1:8 and jordaned; the oil protein is extracted for 30 to 80min by the ratio of the material to water of 1: 10 to 20; the pH value is regulated to be 3 to 8; the material liquid is 30 DEG C to 80 DEG C and slowly stirred for 40 to 80min; supernatant liquid, intermediate liquid and dregs are separated; the supernatant liquid is washed by water and separated into crude oil and water; the pH value of the intermediate liquid is regulated to be 3 to 7 by edible ethanol, and chlorogenic acid is extracted and removed; when the pH value of hydrochloric acid is regulated to be 3 to 7 by protein paste, the acid is precipitated for 60min, and whey water and protein gel are separated; the pH value of the protein gel is regulated after the protein gel is crushed; and then the product is instantly sterilized at 140 DEG C to 160 DEG C of high temperature, and prepared into sunflower protein after being desaerated, homogenated and dried.

Description

The aqua one-step method separation and extraction technology of sunflower seed oil protein

Technical field

The present invention is a kind of sunflower seeds grease new method for extracting, specifically sunflower seeds " aqua one-step method " separating oil, protein process.

Background technology

At present, the oil prodution industry traditional processing technology all is that mechanical expression and solvent (light petrol) leach both at home and abroad, that its drawback is inadequately is economical, safety inadequately, and mechanical expression and solvent leach will be through high-temperature process, make protein denaturation in the grouts, limited its application in food and feed, made it lose edible characteristic and the value of natural green.

Summary of the invention

Goal of the invention of the present invention provides sunflower seeds " aqua one-step method " separating oil, protein extracting method, for guarantee that oil and protein are not polluted and pyrometamorphism by solvent (light petrol) in process, adopt a step separation of produced method of " aqua one-step method " separating oil, protein, and one chlorogenic acid of the nuisance in the albumen removed, improved the quality of made protein, make oil and protein keep original natural edible characteristic, realized that the sunflower seeds resource makes full use of.

Description of drawings

Fig. 1 is the process chart of sunflower seeds of the present invention " aqua one-step method " separating oil, protein extracting method.

The specific embodiment

The aqua one-step method separation and extraction technology of sunflower seed oil protein, main processes:

Raw material is handled: sunflower seeds is after impurity elimination, dedusting, and classification enters decorticator and peels off, and isolates benevolence, shell through machine for separating kernel and shell, and stripping is not returned in clean whole grain sunflower seeds again and peeled off.

Handle early stage: the polly seed nucleole after peeling off is broken into the 6-8 lobe through disintegrating machine and enters in the steeping tank, with the softening hot water of 30-80 ' C in benevolence: water: the immersion of 1: 8 ratio (weight ratio) entered the colloid mill defibrination in 30-80 minute again, and the granularity of slurry is the 40-80 order.

Water is carried: the slurries that mill is good are squeezed into extractor with pump, a certain amount of aqua of adding in jar (material: water: 1: 10-20＜weight ratio 〉) oil in the slurries, albumen are extracted, time is 20-60 minute, send into gravity tank then, and when deployed alkali lye is regulated pH value=3-8 in jar, control feed temperature and about 30-80 ℃, stirred at a slow speed 40-80 minute by adding the hot water mode.

Centrifugation: the slurries that stir enter three centrifuges that separate to be separated, and the seperator separation factor is that 3000-8000 changes, and isolates supernatant, intermediate liquid, slag respectively.

The oil man section: the centrifuge separated liquid supernatant, after washing, enter centrifuge and separate, the centrifuge separation factor is that 8000-12000 changes, and separates fuel-displaced, water, isolated crude oil is made senior sunflower health care oil after conventional refining 6 is taken off.

Albumen workshop section: the isolated intermediate liquid of centrifuge adds edible alcohol by 1: 40 (weight ratio) and mixes, send in the chlorogenic acid extractor, extract when regulating pH value=3-7, the slurries that extracted are sent into centrifuge and are separated, isolate protein milk and solution of chlorogenic acid, solvent is multiplexing after steaming is taken off, and chlorogenic acid is got rid of.Isolate protein milk through seperator and send in heavy jar of the acid, acid is heavy 60 minutes when regulating pH value=3-7 with hydrochloric acid, washes protein precipitation with water.Separate with centrifuge then, separating whey water and protein gel, protein gel is separated broken through machine for decomposing and smashing, regulate pH value according to product requirement, send in the sterilizer high temperature instantaneous sterilization then, spray into through high-pressure pump and steam jar through 140-160 ℃, remove wherein part moisture, and at the bottom of jar, extract out with pump, entering the homogenizer homogeneous and handle, the slip of the sunflower protein behind homogeneous is sent into dry workshop section.

Dry workshop section: with the albumen slurry of sending here, send into spray tower through high-pressure pump, the shower nozzle atomizing, the hot blast of sending here through the air heater heating carries out following current exchange dehydration again, be dried to powder, send into cyclone separator then with the wind, sieve through 100 mesh sieves, will be wherein the bulky grain powder return the heavy workshop section of acid and handle again, qualified albumen powder enters the cloth bag powder extractor case through blower fan and reclaims albumen powder and pack.

This method adopts " aqua one-step method " that albumen in the sunflower benevolence and grease are extracted simultaneously, can significantly reduce investment, condition simplifies the operation, reduce production costs, also (traditional method is 33% to the recovery rate of albumen than high many of traditional method, aqua method is 40%), and do not pass through high-temperature process, basically there is not sex change, can keep the various nutritional labelings of sunflower protein effectively, and, can provide high-quality protein for market, edible health-care oil and protein product to after the extraction of the chlorogenic acid in the sunflower protein.

Sunflower protein contains eight necessary seed amino acids of human body, can be used to the abundant Food ﹠ Drink of production multiple nutrients.These products have very high medical value, can play the effect of removing body's cholesterol, softening blood vessel, stimulating circulation, effectively preventing angiocardiopathy, promoting health, improve whole people's fitness, thereby this method have remarkable economic efficiency and social benefit.
