Description
Technical field
The invention belongs to food processing technology field, relate to a kind of extraction process and the corollary system thereof that contain grease-nut (such as pine nut, walnut) the low grease-nut sauce mud obtaining high-quality vegetables oil and can be used for reprocessing from height, especially a kind of method and system of Extraction parts crude oil from high oil-containing nut spreads mud.
Background technology
Pine nut has another name called sieve pine nut, Korean pine seed, new sieve pine nut, Pinus koraiensis, pinenut, Song Yuan.There is very high nutritive value, and there is certain health-care effect.LI Shi-Zhen once gave very high evaluation to the pharmaceutical use of pine nut, and he writes in Compendium of Material Medica: " Korean pine seed, releases a Xin Luo pine nut, and smell is sweet little nontoxic; Cure mainly joint wind, dizzy, remove dead flesh, bleach, aproll gas, moistening five ZANG-organs, by wandering arthritis cold air, empty thin weak breath tonifying for the deficiency, fertile the five internal organs, loose all wind, wet stomach, takes body for a long time light, prolongs life not old." pine nut is described as by people the desirable health food that " Longevity " is the elderly, is also the desirable food of ladies' moistening skin beautifying.According to surveying and determination, containing a large amount of crude protein, crude fat, polysaccharide, robust fibre in Korean pine benevolence, unsaturated fatty acid content wherein in pine nut is very high, can more than 93% be reached, and the lipid acid containing a kind of uniqueness---Pinolenic acid, and pine nut oil can the activities of antioxidant enzymes of enhancing body, the cardiovascular and cerebrovascular for the elderly has good health-care effect.In addition, the pinenut also trace element such as rich vitamin, mineral substance and calcium, phosphorus, manganese, brill, copper, zinc, iron.Although the nutritive value of pine nut is very high, the food-processing industry of China for the deep processing of pine nut and development ratio very low, directly to eat, be badly in need of exploitation for the processing units of pignolia core or process system.
Walnut nutritious value is enriched, and has the good reputation of " treasured of long live, Longevity, health ".In walnut, lipid content is up to 62%, wherein the fat of 86% is unsaturated fatty acids, and therefore, walnut is the good source of quality plant grease, walnut is rich in copper, magnesium, potassium, vitamin B6, folic acid and VITMAIN B1, also containing fiber, phosphorus, nicotinic acid, iron, Lin Suanna Vitamin B2 Sodium Phosphate and pantothenic acid.Therefore, be that raw-material product is well received by consumers with walnut, walnut is also as one of the first-selected product of health of people health.
In the vegetable protein beverage course of processing, because oleaginousness is higher, not only easily cause the floating of fat, make the greasy feeling of beverage comparatively strong, affect the organoleptic quality of product, and beverage stability is poor, very easily deterioration by oxidation.Current, the extractive technique for nut crude oil is mainly divided into three kinds: organic solvent extraction, supercritical fluid extraction, milling process.Organic solvent extraction can consume a large amount of solvent, and easy contaminate environment, easily exists organic solvent residual in oil, and the band shell nut dregs of rice after extracting can only be used in feed, and comparatively milling process is low for the value of oil; Supercritical fluid extraction extraction yield is high, but energy consumption is high, and the requirement for equipment is higher.Milling process security is higher, oil yield is low, the oily impurity obtained is many, in refining process oil rate of loss large compared with first two, the nut dregs of rice after oil expression utilize scope narrower, and, the method does not almost have effect to some nut (as pignolia core), general containing in its treated seed dregs of rice plants fur clothing or residual shell, and oil pump capacity is few, and range of application is little.Meanwhile, also there is the defect that vegetables oil and the seed dregs of rice can not utilize simultaneously in common method of the prior art.
