Abstract

A meal residue liquid regenerated oil dyeing agent relates to a regenerated edible oil dyeing agent and particularly relates to a regenerated edible oil dyeing agent in oil-water mixed liquid. The meal residue liquid regenerated oil dyeing agent is prepared by dissolving 10g oily blue into 100ml mixed solution of ethyl acetate and dichloromethane (at the ratio of 1 to 1). When the temperature is 0-20 DEG C, 5% methyl tert-butyl ether and 3% methyl acetoacetate are added; when the temperature is 20-40 DEG C, 10% glycol dimethyl ether and 5% methyl acetoacetate are added. The oil is dyed and foods prepared from the oil are colored, so that people are reminded of not eating; the dyeing agent has oleophylic and hydrophobic properties, can be used for dyeing oil but not water, and the environment is prevented from being polluted by generation of wastewater. The meal residue liquid regenerated oil dyeing agent is used for dyeing meal residue liquid regenerated oil.

Description

technical field [0001] The regenerated oil dyeing agent of meal residue liquid relates to a regenerated edible oil dyeing agent, in particular to a regenerated edible oil dyeing agent in an oil-water mixed liquid. Background technique [0002] With the rapid development of the catering industry in modern society, a large amount of meal residues are produced in every city every day. Unscrupulous people extract waste oil from meal dregs and sell it back for consumption, endangering the health of the masses. In order to eradicate the hazards of waste oil, it is necessary to start from the source and use meal residue liquid to separate the oil for dyeing, so as to prevent it from being eaten again. Contents of the invention [0003] The technical problem to be solved by the meal residue liquid regenerated oil dyeing agent is: to dye the regenerated oil extracted from the meal residue liquid. [0004] The technical scheme adopted is: adding a dyeing agent to the oil-water mix...
