Problems solved by technology

[0003] At present, the processing technology of sunflower seed crude oil products mainly has the following problems: the processing technology will generate a lot of waste, which will be discharged randomly and cause serious pollution to the environment; Environmental pollution due to the production of soapstock; the natural VE in the refined sunflower oil is seriously lost, which reduces the quality of the oil; the existing technology cannot completely remove the metal ions, resulting in the oil easily returning to color

Abstract

The invention belongs to the field of physicochemical technologies and discloses a processing method of sunflower seed oil. The processing method comprises the following steps: step 1) of preparing sunflower seed crude oil; step 2) of performing hyperfiltration; step 3) of adsorbing and stirring; step 4) of chelating; step 5) of acidizing and degumming; step 6) of centrifuging and drying; step 7) of crystallizing and removing wax; step 8) of preparing feed additive. According to the processing method disclosed by the invention, processing waste is recycled while oil is processed; the prepared feed additive has a good effect; meanwhile, environmental pollution caused by emission is avoided, and double purposes are achieved.

Description

technical field [0001] The invention belongs to the technical field of physics and chemistry, and specifically relates to a processing method of sunflower oil, and also relates to the application of waste generated during the processing of sunflower oil. Background technique [0002] 90% of sunflower oil is unsaturated fatty acid, of which linoleic acid accounts for about 66%, and also contains vitamin E, phytosterols, phospholipids, carotene and other nutrients. Sunflower oil contains more vitamin E, which can prevent excessive oxidation of unsaturated fatty acids in the body, help to promote the activity of capillaries, improve the circulatory system, and prevent arteriosclerosis and other vascular diseases. The linoleic acid contained in sunflower oil is an essential fatty acid for the human body. It constitutes the basic components of various cells and has the functions of regulating metabolism, maintaining blood pressure balance, and lowering blood cholesterol. Sunflow...
