Abstract
The invention discloses a production process for low-temperature pressed compound rapeseed oil. The process comprises the steps of (1), washing rapeseeds and grape pips clean, drying the rapeseeds and the grape pips until the water content reaches 5-8%, and preparing materials with the weight ratio of the rapeseeds to the grape pips to be 1:(0.1-0.2); (2), frying the dried rapeseeds and the dried grape pips at 50-60DEG C, and pressing the rapeseeds and the grape pips to obtain the oil. According to the process, white vinegar is used for grinding the rapeseeds, the oil yield of the rapeseeds is improved, a modified decolorising agent is used, and decolorizing and heavy metal ion eliminating effects are improved.
Description
Technical field
The present invention relates generally to a kind of rapeseed oil and preparation method thereof, belongs to edible fat production field.
Background technology
Rapeseed oil is exactly our your rape oil of custom, and be again rapeseed oil, caraway oil, squeeze out by Semen Brassicae campestris, be one of Chinese main edible oil, rapeseed oil golden yellow color or pale brown, has certain pungent odour, and among the people drawing is called " blue or green smell ".This smell wherein contains caused by a certain amount of mustard seed ring, but the Semen Brassicae campestris of special quality product kind is not then containing this material.Take from the seed (oil-containing 22%-49%, average 40%) of Brassica napus and Chinese cabbage type oil Lay, containing protein 21%-27%, phosphatide about 1% is one of Chinese main edible oil.There is poisonous residual, the problem such as oil yield is not high, nutritive and health protection components is not enough in existing stir-fry seed rapeseed oil production technique.
Summary of the invention
The object of the invention is just to provide the production technique of the composite rapeseed oil of a kind of low temperature pressing.Production process safety, oil yield is high, adds nourishing function.
The present invention is achieved by the following technical solutions:
A production technique for the composite rapeseed oil of low temperature pressing, is characterized in that: comprise the following steps:
(1), by Semen Brassicae campestris, Semen Vitis viniferae clean up, dry to water content 5-8%, prepare burden by Semen Brassicae campestris, Semen Vitis viniferae weight ratio 1:0.1-0.2;
(2), Semen Brassicae campestris, the Semen Vitis viniferae after drying is fried at 50-60 DEG C after, squeeze fuel-displaced;
(3), be separated after obtain Semen Brassicae campestris, Semen Vitis viniferae slag, put into after water vapor steams 20-30 minute, take out that to add 3-5% light-coloured vinegar be medium milling, leave standstill, filter and obtain vinegar mill oil;
(4), pressed oil and vinegar grinds after oil merges, adds and is equivalent to the oil heavy deionized water of 50-60%, the citric acid of 0.5-1.5%, be heated to 80-90 DEG C, stir 30-40 minute, staticly settle 5-6-hour, filtration impurity elimination; Then, then add the sodium bicarbonate being equivalent to the heavy 1-2% of oil, dissolve in aqueous phase, be heated to 40-50 DEG C, stir 30-40 minute, leave standstill, filter and remove precipitation; Then, make oily water separation, the oil dehydration after separation;
(5), oil is through decolouring, filtration;
(6), clean composite oil is obtained.
The production technique of the composite rapeseed oil of described low temperature pressing, it is characterized in that in described step (5), decolouring adopts discoloring agent to be obtained by the raw material of following weight part: wilkinite 10-12, bamboo charcoal 6-8, preparation method is roasting 3-4 hour at wilkinite is put into 450-500 DEG C, take out, wilkinite mixes with bamboo charcoal, put into the mature vinegar of 6-9%, soak 12-15 hour, filter and take out, the sodium hydrogen carbonate solution putting into 10-12% again soaks 3-4 hour, then the cleaning of taking-up use water is filtered repeatedly, 10-15 minute is stirred under 14000-16000 rev/min of condition, dry and get final product.
The present invention adopts vinegar mill, low temperature pressing technique, namely remains the advantage of cold press, and meanwhile, vinegar mill improves oil yield, can kill poisonous and harmful substances, improves the quality of oil.Raisin seed oil can increase the health value of rapeseed oil.
Embodiment
A production technique for the composite rapeseed oil of low temperature pressing, comprises the following steps:
(1), by Semen Brassicae campestris, Semen Vitis viniferae clean up, dry to water content 5-8%, prepare burden by Semen Brassicae campestris, Semen Vitis viniferae weight ratio 1:0.12;
(2), Semen Brassicae campestris, the Semen Vitis viniferae after drying is fried at 50-60 DEG C after, squeeze fuel-displaced;
(3), be separated after obtain Semen Brassicae campestris, Semen Vitis viniferae slag, put into after water vapor steams 20-30 minute, take out that to add 3-5% light-coloured vinegar be medium milling, leave standstill, filter and obtain vinegar mill oil;
(4), pressed oil and vinegar grinds after oil merges, adds and is equivalent to the oily deionized water of heavy 50-60%, the citric acid of 1.5%, be heated to 80-90 DEG C, stir 30-40 minute, staticly settle 5-6-hour, filtration impurity elimination; Then, then add be equivalent to oil weigh 2% sodium bicarbonate, dissolve in aqueous phase, be heated to 40-50 DEG C, stir 30-40 minute, leave standstill, filter remove precipitation; Then, make oily water separation, the oil dehydration after separation;
(5), oil is through decolouring, filtration;
(6), clean composite oil is obtained.
In step (5), decolouring adopts discoloring agent to be obtained by the raw material of following weight part (kilogram): wilkinite 10, bamboo charcoal 6, preparation method is roasting 3-4 hour at wilkinite is put into 450-500 DEG C, take out, wilkinite mixes with bamboo charcoal, puts into the mature vinegar of 6-9%, soak 12-15 hour, filter and take out, then the sodium hydrogen carbonate solution putting into 10-12% soaks 3-4 hour, then filter the cleaning of taking-up use water repeatedly, under 14000-16000 rev/min of condition, stir 10-15 minute, dry and get final product.
