Abstract
The invention discloses a preparation process for low-temperature cold-pressed carotene-rich peanut oil. The process is characterized by comprising the steps of (1), removing shells and red skins of peanuts, drying the peanuts until the water content reaches 5-8%, and crushing the peanuts; weighing carrots with the weight equivalent to 20-25% of that of the peanuts, and washing the carrots clean; (2), sending crushed peanut kernels into an oil press to extract oil, so that the virgin peanut oil is obtained. According to the process, vinegar grinding, wine grinding and cold pressing technologies are adopted, the advantages of initial pressing are reserved, meanwhile, the oil yield can be improved by the vinegar grinding and the wine grinding, poisonous and harmful substances can be killed, and the quality of the peanut oil is improved. The peanut oil is rich in carotene and beneficial to human health.
Description
Technical field
The present invention relates to a kind of method of low-temperature cold pressing peanut oil, belong to the plant oil processing technique field.
Background technology
Peanut oil is a kind of Vegetable oil lipoprotein take peanut as waste, and it is nutritious, wherein contains abundant unsaturated fatty acids, vitamin-E, trans-resveratrol, β-sitosterol etc.The extracting process of the present peanut oil of China has two classes: hot moulding method and cold-press.
Peanut can cause because pressing temperature is too high nutritive ingredient loss and the peanut protein sex change such as linolenic acid in peanut, linolic acid, vitamin-E in the hot moulding process.There is the not high problem of oil yield in cold press.How to get rid of the pollution of flavacin in the peanut oil squeezing process, increase beneficiating ingredient, guarantee HUMAN HEALTH, need the improvement of research technique.
Summary of the invention
The purpose of this invention is to provide the preparation method that a kind of low-temperature cold pressing is rich in the peanut oil of carotene, oil yield is high, and the peanut oil of production meets national standard, is rich in carotene, useful HUMAN HEALTH.
Technical scheme of the present invention is as follows:
A kind of low-temperature cold pressing is rich in the preparation method of the peanut oil of carotene, it is characterized in that comprising the following steps:
(1), with peanut except shell, slough scarlet, dry to water content 5-8%, and pulverize; Take the Radix Dauci Sativae that is equivalent to peanut weight 20-25%, clean;
(2), the Semen arachidis hypogaeae after pulverizing sends into the oil press zhai squeezing and gets oil, obtain just expressing oil from peanuts;
(3), the peanut cake after squeezing takes out, and puts in the lump steamer with Radix Dauci Sativae, steamed 10-15 minute in 100-110 ℃ of steam; Then will be take the white wine of 10-15% as medium milling, standing, filter and obtain wine mill peanut oil;
(4), peanut meal after vinegar mill and carrot pomace are carried out regrind with the light-coloured vinegar of 1-5%, standing, filtration obtains vinegar and grinds peanut oil;
(5), will just express oil from peanuts, vinegar mill peanut oil, wine mill peanut oil merges, and adds the deionized water that is equivalent to the heavy 50-60% of oil, the sodium bicarbonate of 1.5-3.5%, is heated to 60-70 ℃, stirs 30-40 minute, staticly settles 5-6-hour, the filtration impurity elimination; Then, then add the citric acid that is equivalent to the heavy 1-2% of oil, in the aqueous phase dissolving, be heated to 40-50 ℃, stirred 30-40 minute, precipitation is removed in standing, filtration; Then, make oily water separation, the peanut oil dehydration after separation;
(6), peanut oil is through decolouring, filtration;
(7), obtain clean peanut oil.
described low-temperature cold pressing is rich in the preparation method of the peanut oil of carotene, it is characterized in that in described step (6), decolouring adopts discoloring agent to be made by the raw material of following weight part: wilkinite 10-12, bamboo charcoal 6-8, the preparation method puts into wilkinite 450-500 ℃ of lower roasting 3-4 hour, take out, wilkinite mixes with bamboo charcoal, put into the citric acid of 6-8%, soaked 12-15 hour, filter and take out, the sodium hydrogen carbonate solution of putting into again 10-12% soaked 3-4 hour, then filter and take out the water cleaning repeatedly, stirred 10-15 minute under 14000-16000 rev/min of condition, dry and get final product.
The present invention adopts vinegar mill, wine mill, cold pressing process, the advantage that has namely kept first press for extracting juice, simultaneously, vinegar mill, wine mill improve oil yield, can kill poisonous and harmful substances, improve the quality of peanut oil, the present invention increases Radix Dauci Sativae as raw material, improved the content of carotene in peanut oil, useful HUMAN HEALTH.
