Example Embodiment

[0018] Example 1:

[0019] A preparation method for improving the antifreeze property of rapeseed oil includes the following steps:

[0020] (1) Raw material impurity removal: use 80-100 mesh screen to remove light impurities from the rapeseed mixture, and place it in an electromagnetic vibrating screen to vibrate to remove metal impurities, where the electromagnetic can adsorb the metal impurities in the mixture;

[0021] (2) Stir-frying: After removing impurities, the rapeseed mixture is fried and micronized by microwave heating to obtain the rapeseed mixed powder. The energy generated by the microwave can destroy the cells and promote the release of intracellular components. The raw material is micronized in the subsequent processing The contact area with the enzyme is enlarged to improve the efficiency of enzymatic hydrolysis;

[0022] (3) Enzymatic hydrolysis: add mixed enzyme solution a to the rapeseed mixed powder, cellulase and pectinase can dissolve the plant cell wall, promo...

Example Embodiment

[0031] Example 2:

[0032] Comparing this embodiment 2 with embodiment 1, the main step changes are as follows:

[0033] For the rapeseed mixture described in step (1), the mass parts of the ingredients are:

[0034] 47 parts of rapeseed, 8.5 parts of camellia seeds, 7 parts of sunflower seeds, 2.6 parts of pecan kernels, 4.2 parts of whole wheat, mixed well to obtain a mixture.

[0035] The microwave heating frying described in step (2) has a heating temperature of 66°C and a frying time of 29 minutes.

[0036] The mixed enzyme solution a of step (3), wherein the mass ratio of pectinase and cellulase is 1:3, the mass concentration of the mixed enzyme is 6.2%, the enzymolysis temperature is 44°C, and the enzymolysis time is 2h; Mixed enzyme solution b, in which the mass ratio of protease and lipase is 8:1, the mass concentration of mixed enzyme is 3%, the added amount is 9% by mass of rapeseed batter, the enzymolysis temperature is 41℃, and the enzymolysis time is 0.8h .

Abstract

The invention discloses a preparation method of rapeseed oil with high anti-freezing property. The method is characterized by comprising the following steps: (1) removing impurities of raw materials, specifically, using a filter screen and an electromagnetic vibrating screen to remove light and metal impurities in a mixture; (2) frying, specifically, frying the rapeseed mixture by means of microwave heating, and then carrying out micronizing treatment on the fried rapeseed mixture; (3) carrying out enzymolysis, specifically, adding mixed enzyme a and mixed enzyme b into rapeseed mixed powder, and carrying out enzymolysis at constant temperature; (4) steaming the obtained material, specifically, steaming the molded rapeseed cake at the low temperature and the high temperature; (5) extracting, specifically, carrying out squeezing extraction on the rapeseed cake in a vertical squeezer, and then soaking the squeezed rapeseed cake in 95% ethanol for extracting; (6) curing for storing, specifically, storing the extracted rapeseed oil for 2-3 days at the temperature of 9-13 DEG C, and curing. The preparation method of the rapeseed oil can effectively improve the anti-freezing property of rapeseeds, increases the rapeseed oil extraction rate by 12.33%, and reduces the processing cost of the rapeseed oil by 17.3%.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and in particular relates to a preparation method for improving the antifreeze property of rapeseed oil. Background technique [0002] Rapeseed oil, also known as rapeseed oil, coriander oil, and canola oil, is one of the main edible oils in my country. The human body can absorb 99% of rapeseed oil. It has the effects of softening blood vessels and delaying aging. The phospholipids and low cholesterol contained in it can not only promote the development of blood vessels, nerves, and brain, but will not cause long-term consumption of cholesterol to increase. However, due to the wide range of consumption of rapeseed oil, the temperature varies greatly from place to place, especially in winter when the temperature can drop to tens of degrees below zero, and the temperature in the north is basically maintained at around -10°C. However, rapeseed oil gradually becomes turbid at -5°C, form...
