Abstract
The invention relates to the technical field of food processing and discloses a production process for improving oil yield of healthy pressed rapeseed oil. The production process for improving the oil yield of the healthy pressed rapeseed oil comprises the following steps: (1) selecting rapeseeds, and respectively removing sundries on the rapeseeds by virtue of thick and thin sieves; (2) soaking the screened rapeseeds for 1.5-4 hours with solution; (3) putting the soaked rapeseeds into an ultrasonic instrument to be subjected to ultrasonic treatment for 30-60min for three times; (4) draining the treated rapeseeds, smashing, and carrying out microwave irradiation heating on the crushed rapeseeds, so as to promote oil containing cells to be fully fractured; and (5) after microwave irradiation is finished, steaming and frying for reducing moisture content of the rapeseeds to 5-15%, wherein the rapeseeds are fired with a big fire, after about half hour, the rapeseeds are fired with a small fire and right amount of coarse bran is added and fried together; and when temperature of the rapeseeds reaches 100-150 DEG C, taking out the rapeseeds from a pot, and pressing. The production process provided by the invention can eliminate glucosinolate in the rapeseeds, so that 'green smell' of rapeseed oil is eliminated, and the rapeseed oil is green and healthy; meanwhile, oil yield of the pressed rapeseed oil is improved by 14%, and cost of the rapeseed oil is reduced.
Description
Technical field
The present invention relates to food processing technology field, be specifically related to a kind of production technique improving healthy squeezing rapeseed oil oil yield.
Background technology
Rapeseed oil is called for short " rape oil ", general in deep yellow or brown, containing eicosanoic acid 0.4-1.0% in rapeseed oil, oleic acid 14-19%, linolic acid 12-24%, erucic acid 31-55%, linolenic acid 1-10%, from nutritive value aspect, human body up to 99%, and can have cholagogic function to rapeseed oil digestibility.The nutritive ingredients such as unsaturated fatty acids and vitamin-E such as the linolic acid contained by it can be absorbed by body well, the effect have certain vessel softening, delaying senility; Rapeseed oil generally can contain certain seed phosphatide, very important to the growth of blood vessel, nerve, brain; The cholesterol of conventional rapeseed oil seldom or hardly contains, so the people controlling cholesterol intake can relievedly eat.
The extraction of rapeseed oil mainly contains two kinds of processing methodes, Chemical Leaching and physical squeezing.Chemical Leaching is after vegetable seed is pressed into broken thin slice, and soaked in solvent, makes lipid solubilization form mixing oil in solvent oil, then adds heat extraction solvent oil, and the crude oil obtained comes unstuck through chemical high temperature refinery, decolour, deodorization, filtration finally make edible oil.Although lixiviation process liquefaction oil yield is high, tooling cost is low, have trace level chemical substance and remain, destroy the nutritive element such as unsaturated fatty acids and vitamin-E zinc, iron, life-time service can bring healthy hidden danger to the mankind.Therefore along with the raising of people's green health consciousness, physical squeezing oil more and more obtains popular favor.
Physical squeezing is the technique utilizing mechanical expression technique that oil is squeezed out from vegetable seed.Physical squeezing does not use chemical reagent, and without chemical residual, but oil yield rate is low, and in crushed oil cake, residua content is higher, so cost is high.In addition, containing a certain amount of sinigrin in vegetable seed, there is certain pungent odour, people claim its " blue or green smell ", also limit the edible crowd of rapeseed oil, therefore, remove blue or green smell ", improve the oil yield rate of squeezing rapeseed oil, reducing costs is the focus of physical squeezing technical study person.
Summary of the invention
The invention provides a kind of production technique improving healthy squeezing rapeseed oil oil yield, can eliminate " the blue or green smell " of rapeseed oil, improve the oil yield of rapeseed oil, thus reduce rapeseed oil cost.
In order to realize above object, the present invention is implemented by the following technical programs:
Improve a production technique for healthy squeezing rapeseed oil oil yield, comprise the following steps:
(1) the full vegetable seed do not gone mouldy is chosen, and Chu Qu silt, dust and other impurities on vegetable seed with thickness screening;
(2) the vegetable seed solution soaking of will screen, soak time is 1.5-4h;
(3) soaked vegetable seed is put into ultrasonic apparatus and carry out supersound process, number of processes is 3 times, and each treatment time is 30-60min;
(4) vegetable seed after process is drained, add in pulverizer and carry out fragmentation, the vegetable seed after fragmentation is carried out microwave exposure heating and impel oil cell fully to break;
(5) carry out steaming after microwave radiation to fry, the water content of vegetable seed is made to drop to 5%-15%, fry with big fire during beginning, after about 0.5 hour, in pot, vegetable seed has jarring, transfers little fighting to and adds appropriate chaff and fry together, period wants duty to stir, avoid phenomenon of the burnt end, when in pot, vegetable seed temperature reaches 100 ~ 150 DEG C, can take the dish out of the pot squeezing.
Preferably, in described step (2), the amount of soaking solution is 10-15 times of vegetable seed weight.
Preferably, in described step (2), soaking solution is the aqueous solution that with the addition of myrosinase, and wherein the consumption of myrosinase is the 0.1%-0.5% of vegetable seed weight.
Preferably, in described step (3), ultrasonic frequency is 25-30 kilohertz.
Preferably, the vegetable seed granularity in described step (4) after fragmentation is 10-20 order.
Preferably, the middle carry out microwave radiation heating temperature of described step (4) is to 60-90 DEG C.
Preferably, the amount of the chaff mixed in described step (5) is the 0.4%-0.8% of vegetable seed weight.
Preferably, the temperature head of expressing process vegetable seed of taking the dish out of the pot in described step (5) remains within 20 DEG C.
Beneficial effect of the present invention: with the aqueous solution soaking vegetable seed of myrosinase in production technique of the present invention, it is the sinigrin in order to decompose in vegetable seed, then use ultrasonic method to be cleaned up by the resolvent on vegetable seed surface, completely eliminate like this " the blue or green smell " of rapeseed oil.This technique green health, and the oil yield of squeezing rapeseed oil improves 14%, thus reduce rapeseed oil cost.
