Zero trans fat acid corn oil and refining process thereof

Abstract

The invention provides zero trans fat acid corn oil and a refining process thereof. The appropriate processing of corn oil is achieved through the processes of alkali refining, dewaxing, decolorizing, deodorizing and packing of crude corn oil to produce the zero trans fat acid corn oil. The refining process is characterized in that the corn oil is decolorized after being dewaxed, and the decolorized corn oil is deodorized, wherein the dewaxing procedure adopts a corn oil tubular continuous dewaxing technology, and the deodorizing procedure adopts a dual-temperature and dual-tower deodorizing technology. The zero trans fat acid corn oil has the advantages that the trans fat acid content is less than or equal to 0.3%, the Vitamin E content is larger than or equal to 1,000 mg / kg, the phytosterol content is larger than or equal to 10,000 mg / kg, any chemical synthesis antioxidants and nutrition enhancers are not added, and the corn oil is more nutritious and safer and is beneficial to long-term health of people.

Description

technical field [0001] The invention belongs to the field of corn oil processing, and in particular relates to a zero-trans fatty acid corn oil and a refining process thereof. Background technique [0002] With the advancement of technology, the quality of corn oil mostly meets the national standards, and the quality problems have been solved, but there are many hidden dangers in the nutrition problem. On the one hand, the corn oil produced by the traditional oil-making process has a relatively high content of trans fatty acids. Trans fats are produced in the process of partial hydrogenation of vegetable oils. High levels of trans fatty acids will increase blood cholesterol levels, Lead to the occurrence of cardiovascular diseases, increase blood viscosity and cohesion, promote thrombosis, increase low-density lipoprotein, that is, "bad lipoprotein", reduce high-density lipoprotein, that is, "good lipoprotein", and promote arteriosclerosis , promote the occurrence of type 2...

AI Technical Summary

Problems solved by technology

On the one hand, the corn oil produced by the traditional oil-making process has a relatively high content of trans fatty acids. Trans fats are produced in the process of partial hydrogenation of vegetable oils. High levels of trans fatty acids will increase blood cholesterol levels, Lead to the occurrence of cardiovascular diseases, increase blood viscosity and cohesion, promote thrombosis, increase low-density lipoprotein, that is, "bad lipoprotein", reduce high-density lipoprotein, that is, "good lipoprotein", and promote arteriosclerosis , promote the occurrence of type 2 diabetes, and for infants and young children, trans fatty acids can also affect growth and development, and have adverse effects on the development of the central nervous system; It is manifested in the addition of white clay, high temperature and long time in decolorization and deodorization process, etc. Excessive refining will not only cause waste of resources and energy, aggravate environmental pollution, cause loss of oil, but also cause loss of nutrients in corn oil itself (such as vitamin E, sterol content)
