Problems solved by technology

[0004] (2) The nutrient composition of rapeseed oil is worse than other vegetable oils. Among them, the content of linoleic acid, which is necessary for the human body, is low, only 1-14%, while the content of linolenic acid is high, as high as 9-11%, making the rapeseed oil The oil is difficult to store, and because of the special smell of the oil, it also affects the consumption of residents

Embodiment

[0009] The method for improving edible oil provided by the invention uses vegetable oil or animal oil as a raw material, uses the self-catalysis of bran oil to cooperate with the 2-3 kinds of vegetable oil or animal oil to carry out oil reformation by transesterification reaction, controls the feeding ratio, and retains vitamins A, B, C, E, and oryzanol; the control feed ratio is based on saturated fatty acid: oleic acid: polyenoic acid = 1:2:1 to calculate the feed ratio, through oil reforming to achieve oleic acid in the finished oil The content of erucic acid and polyenoic acid all reaches within 35 ± 2%; the self-catalysis of the bran oil is to use the monoglyceride or diglyceride present in the oil as a reaction catalyst to carry out oil reformation, so that the erucic acid content in the finished oil Below 10%; the retention of vitamins A, B, C, E, and oryzanol is through the control of free fatty acids, within the range of 1-2%, so that the oryzanol content in the refine...

example 1

[0011] Get 100 grams of rapeseed oil, 70 grams of degummed, dewaxed bran oil, put it into a three-necked flask with a stirrer, and its capacity is 350 milliliters, heat up and react for 4 hours under nitrogen, and the initial Engler viscosity is 7.8 (50 ° C) , The end point is 2.8, and then through deacidification, decolorization, deodorization, makes 120 grams of product oils.

example 2

[0013] Put 500 catties of rapeseed oil and 400 catties of bran oil into a 1500 liter enamel reaction kettle, stir at 70-80 rpm, vacuum at 740 m / mHg column, heat up and react for 2 hours, deacidify and decolorize , deodorized, and the obtained refined oil is 950 jin.

Abstract

The invention provides an edible oil improvement method, and belongs to the technical field of chemical modification of plant oil. An ester exchange process is mainly adopted, millet bran oil is utilized to autocatalyze the cooperation of the millet bran oil and 2-3 animal and plant oils, feeding is reasonably calculated to carry out an oil reforming technology in order to realize a reasonable form of aliphatic acid in product oil, effectively reserve oryzanol, vitamin A, vitamin B, vitamin C and vitamin E and reduce the content of erucic acid. Edible oil has good health effects, is sufficient, and has a low price and a substantial economic benefit, so the method expands the domestic and foreign market access of vegetable oil and bran oil, and also provides an access for the exploitation and comprehensive utilization of the animal and plant oils.

Description

technical field [0001] The invention belongs to the technical field of chemical modification of animal and vegetable oils, and in particular relates to a method for improving edible oils. Background technique [0002] There is a precedent for the use of transesterification in oil processing in foreign countries, and the United States earlier used transesterification to modify lard. Although in the future, the raw materials and the scope of use have been expanded, but they are all based on the use of solid oil or semi-solid oil as the reaction object. Due to the limited price and output of raw materials and catalysts, industrial mass production is also limited, and they can only be used for food processing. On the one hand, it is difficult to become a daily dietary necessity for the majority of residents. In addition, up to now, two reactions have been selected simultaneously to displace and rearrange erucate glycerides, especially the combination of rapeseed oil and bran oi...
