Abstract
A walnut oil extraction process by supercritical carbon dioxide is disclosed. Walnut oil is prepared by steps of peeling walnut kernels, roasting, smashing, extracting, separating, and the like. The process and equipment procedures are simple. The process adopts supercritical extraction. The process is energy-saving, safe, and pollution-free, and prevents the problems of toxicity and harm to human bodies and environment pollution during the extraction. Compared with traditional processes, the process can protect various nutrition components from being damaged in a squeezing step, so that the oil has characteristics of natural faint scent, original taste and flavour, capability of being green and healthy, and comprehensive nutrition.
Description
Technical field
The present invention relates to a kind of extracting method of walnut oil, particularly relate to a kind of technical process of supercritical carbon dioxide extraction walnut oil, belong to food processing field.
Background technology
China has extremely abundant petal resource, and walnut kernel is familiar with by domestic and international very early as health care dried fruit product, and walnut kernel nature and flavor are sweet flat, gentle, the effect that have kidney-replenishing blood-nourishing, moistening lung Dingchuan, relaxes bowel.The simultaneously still cosmetic good merchantable brand of blacking hair and nourishing face, moisturizing health care simply of walnut kernel.Walnut kernel has the effect that strong kidney nourishes blood, so, take for a long time walnut and can make hair pitch-black glossy, to hair color, to send out withered not flourish has good curative effect.Ancient medicine man is early recognized for the pharmaceutical use of walnut kernel, and they think that informal dress walnut kernel makes us eating, and kindred is moist, the black pool of beard and hair, Xuemaitong profit.Shennong's Herbal by walnut classify as clothes of a specified duration make light of one's life by commiting suicide beneficial gas, promote longevity top grade.In numerous work in Meng the Tang Dynasty " Shiliao Bencao ", describe, eating walnut kernel can whet the appetite, and logical profit blood vessels, make kindred exquisiteness.In the works such as Song dynasty Liu Han " Kaibao Bencao ", describe, and walnut kernel " order of food is fertile strong, profit flesh, and black beard and hair, eats sharp little water more, goes five hemorrhoid." Ming Dynasty's LI Shi-Zhen work Compendium of Material Medica description, walnut kernel has effects such as " the beneficial gate of vitality, locate three warmers for benefiting qi and nourishing blood, moistening the lung and resolving the phlegm, and warm lung ease constipation, controls the cold of insufficiency type and breath with cough, and waist pin heavily aches, trusted subordinate's colic, bloody flux intestines wind ".
Walnut kernel oil length is 55%～70%; walnut oil is rich in unsaturated fatty acids; as linolic acid, linolenic acid; account for more than 90%; walnut oil is the elite of walnut; there is brain tonic and intelligence development; mend brain, improve one's memory, promote brain and nervous system development, promotion retinal development, promote calcium absorption to help skeleton development, protection stomach, relax bowel, moisten the bottom of heart, promote natural on-off cycles of hair growth, prevention and alleviate the effects such as skin eczema, enhancing development, balance metabolism, so walnut kernel and oil are precious medicine and healthcare products.
In " Chinese Food structure improvement and development planning outline ", walnut oil is listed in advocates the edible oil of promoting energetically, the method of preparing now walnut oil mainly contains milling process production technique and organic solvent lixiviation process production technique, the crude oil impurity that milling process production technique is produced is more, need be through high temperature and chemical process processing, high-temperature time is long, and product formation mode acid lipid, is unfavorable for HUMAN HEALTH; Wet distillation grease easily hydrolysis makes unsaturated fatty acids have the generation of polymkeric substance, easily cause loss and the destruction of the nutrition benefit materials such as vitamin-E in oil, carotene, plant sterol and trace element, make protein denaturation, its water-soluble protein content obviously declines, and has reduced nutritive value and the functional performance of walnut oil itself; The crude oil that organic solvent lixiviation process production technique is produced has organic solvent residual, unfavorable to HUMAN HEALTH.
Summary of the invention
The object of the invention is to the deficiency for background technology, a kind of technique of supercritical carbon dioxide extraction walnut oil is provided.
The present invention is achieved through the following technical solutions:
A technique for supercritical carbon dioxide extraction walnut oil, it is made by following steps:
1), walnut is through rejuvenator broken shell, after separation of hull from kernel, selects walnut kernel, walnut kernel put into the hot water of 86 DEG C of temperature, soaks after 8 minutes hot water is discharged, and with the cooling flushing walnut kernel of cold water, removes attached skin simultaneously;
2) walnut kernel of peeling is toasted 3～5 hours at the temperature of 50～60 DEG C, or put into frying pan, frying 25～30 minutes, temperature is 95～105 DEG C;
3) walnut kernel step 2 being made is put into pulverizer and is pulverized 30～50 order fineness;
4) walnut kernel after pulverizing is dropped in extraction kettle, spe medium carbonic acid gas is entered to extraction kettle after under meter metering, controlling supercritical extraction temperature is 40～45 DEG C, supercritical extraction pressure is 36～40Mpa, carbon dioxide flow is 300～550 ls/h, and extraction time 2～3 hours, then starts release, in stress-relief process, make pressure be reduced to gradually normal pressure, generate the mixture of degreasing walnut benevolence, liquid carbon dioxide and walnut oil;
5) mixture that step 4 is extracted to the degreasing walnut benevolence, liquid carbon dioxide and the walnut oil that make is put into oil-liquid separator, controls 50～70 DEG C of separating pressure 15～20Mpa, separation temperatures, and walnut oil is separated from oil-liquid separator;
6) walnut oil step 5 being made enters decolouring oil tank, the vacuum keep of decolouring oil tank is at 550～600mm mercury column, and oil temperature remains on 85～95 DEG C, adds the activated carbon of walnut oil weight 0.6%, after under agitation decolouring 30 minutes, filter and remove impurity, get product;
Further, in described step 6, stirring velocity remains on 55～65r/min, and filtration temperature remains on 60～65 DEG C.
Further, in described step 6, available supercentrifuge is processed and is removed impurity.
The invention has the advantages that:
1, Processes and apparatus flow process is simple, adopts supercritical extraction, energy-conservation, safe, pollution-free, can guarantee that various nutritive ingredients are not destroyed in expressing process, thereby make oily smell natural faint scent, genuineness, green health, comprehensive nutrition than traditional technology.
2, effectively avoided the residual of solvent toxicity under traditional extraction conditions, also the central murder by poisoning to human body of leaching process and the pollution problem to environment have been prevented simultaneously, extraction temperature is low simultaneously, the bioactive ingredients of retained product preferably, is protein powder after the walnut kernel after extraction walnut oil is dried.
