Embodiment 1

[0013] Example 1 Take a certain amount of grease with a peroxide content of 21.51meq / kg and place it in an airtight container filled with inert gas. After placing the container at a constant temperature of 20°C for 300 days, the grease peroxide decomposes and the content is reduced to 5.56meq / kg. reached 74%.

Embodiment 2

[0014] Example 2 Take a certain amount of grease with a peroxide content of 22.37meq / kg and place it in an airtight container filled with inert gas. After placing the container at a constant temperature of 40°C for 60 days, the grease peroxide decomposes and the content is reduced to 7.16meq / kg. reached 68%.

Embodiment 3

[0015] Example 3 A certain amount of oil with a peroxide content of 21.96 meq / kg was filled into a closed container, and the oil in the container was kept at a constant temperature of 90 °C for 14 hours. The peroxide content of the oil was reduced to 18.84 meq / kg, and the reduction rate reached 17%.

Abstract

The invention discloses a method for decomposing peroxides in oils. Under the environmental conditions of fully isolating air and oxygen, the oils are kept at a constant temperature of 20°C to 300°C for 300 days to 5 seconds to decompose the peroxides in the oils and reduce the oil content. the peroxide content; the present invention can safely and effectively decompose the peroxide in the oil, reduce the peroxide content of the oil, the final product has low peroxide content, high safety and stability; The requirements for the experiment are not high, it is easy to implement, and the process cost is low, so it can be considered for industrial application and large-scale production.

Description

technical field [0001] The invention relates to a method for decomposing peroxides in oil and reducing the content of oil peroxides, belonging to the technical field of food chemistry. Background technique [0002] The safety of edible oils and fats is a major issue related to people's health. For a long time, people lack sufficient understanding of the hygiene and safety of edible oils, especially the hazards of oxidative rancidity of vegetable oils rich in unsaturated fatty acids have not been taken seriously. After long-term storage, due to the influence of light, air, temperature and other factors, oils are prone to oxidative rancidity. Severely oxidized and rancid oils are inedible. Not only the nutritional value is reduced, but also it can cause many diseases. [0003] The intermediate product peroxide in the process of oxidative rancidity of oil is produced by the oxidation of oil and oxygen in the air. It is highly active and can continue to decompose to produce vo...
