Abstract

The invention relates to a preparation method of a deacidifying agent with lotus leaves and belongs to the technical field of preparation of the deacidifying agent. For solving the problem that an adsorption deacidifying agent in the prior art has single effect and high limitation, cannot effectively remove oleic acid, and is liable to decompose during adsorption. The preparation method includes the steps of: drying and grinding fresh lotus leaves, extracting nuciferine under ultrasonic wave, grinding and activating dried lotus leaves to prepare a microporous deacidifying agent supporter, and compositing the nuciferine with the microporous deacidifying agent supporter to support the nuciferine onto the activated deacidifying agent supporter to effectively remove oleic acid in plants. The deacidifying agent has low oil loss rate being only 0.1% and is improved in adsorption efficiency by 25-30% than other deacidifying agents, is simple in preparation process, is green and environment-friendly and is free of environment pollution.

Description

technical field [0001] The invention relates to a preparation method of lotus leaf deacidification agent, belonging to the technical field of deacidification agent preparation. Background technique [0002] Oil refining is to process a certain quality of oil to be refined into finished oil that meets the quality requirements. The essence of this process is to remove the non-neutral oil components in the oil to be refined, so as to obtain relatively pure finished oil, that is, neutral oil. Purification process. Generally speaking, oil refining mainly includes oil filtration, degumming, deacidification, decolorization, deodorization, winterization, dewaxing and other processes. Among them, the oil that has been filtered, degummed, and deacidified is called semi-refined oil, while the oil that has been decolorized, deodorized, winterized, and dewaxed is called refined oil. Generally, unrefined crude oil contains a certain amount of free fatty acid, and the process of removing...
