Problems solved by technology

[0003] However, due to the high content of unsaturated fatty acids contained in rapeseed oil, unsaturated fatty acids are easily oxidized and deteriorated to form peroxides and other substances that are harmful to human health during the frying process.

Abstract

The invention relates to the technical field of agricultural and sideline product processing, and discloses a method for reducing the deterioration speed of rapeseed oil in a frying process. Accordingto the invention, the physical and chemical properties and the cooking taste of oil frying are studied, so that the problem that the rapeseed oil is oxidized and deteriorated to generate harmful substances in the high-temperature frying process is solved, the thermal oxidation, thermal polymerization, thermal decomposition and oxidation reactions are prevented under the frying high-temperature condition, the taste of the erucic acid in the rapeseed oil can be covered by adding the prepared anti-oxidation protection agent, the taste of the dish is not affected, the generation of the fragrancein the cooking can be promoted, and the food material processing is facilitated; the method comprises: preparing low-fat rapeseed oil by adopting a low-temperature squeezing method, adding a preparedanti-oxidation protection agent, and finally blending; and the process can well solve the disadvantage of high-temperature intolerance and easy deterioration of the existing rapeseed oil, is not addedwith harmful substances in the treatment process, has characteristics of no impurity residue, simple technology and low cost, and improves the utilization rate of the rapeseed oil in the frying process.

Description

technical field [0001] The invention belongs to the technical field of agricultural by-product processing, and in particular relates to a method for reducing the deterioration speed of rapeseed oil during frying. Background technique [0002] The human body has a very high absorption rate of rapeseed oil, which can reach 99%. Therefore, the unsaturated fatty acids such as linoleic acid and vitamin E and other nutrients contained in it can be well absorbed by the body, and it has a certain effect of softening blood vessels and delaying aging. its effect. Since the raw material for oil extraction is the seeds of plants, one strand will contain a certain amount of seed phospholipids, which is very important for the development of blood vessels, nerves, and human brain. Rapeseed oil has very little or almost no cholesterol, and people with three highs can also eat it with confidence. [0003] However, due to the high content of unsaturated fatty acids contained in rapeseed oil...
