Embodiment 3

[0086] Process test for main process optimization.

[0087] In order to realize the above-mentioned technical scheme, we conducted a large number of process experiments in the early stage, and explored and compared each process flow and parameters. Now we select the optimization process of key control points such as extraction solvent, extraction times, and refined alcohol precipitation to describe.

[0088] 1) Selection of extraction medium

[0089] The main components of vegetable oil unsaponifiables are fat-soluble components. According to the solubility preliminary experiment, it is soluble in hot ether, ethyl acetate, n-hexane, n-butanol and cyclohexanol, so these solvents are selected in this experiment. Compare. Among the three types of main components of unsaponifiable matter, sterol content accounts for the largest proportion, and its molecular structure has a certain polarity, so the total sterol content is the preferred index for investigation, and the yield of tot...

Abstract

The invention relates to a preparation method for extracting total unsaponifiable matters from vegetable oil and belongs to the technical field of food and medicines. The preparation method comprises the following steps of S1, oil enhanced alkali saponification, S2, soap base separation and drying, S3, solvent addition and extraction, S4, filtration to obtain an extracting solution, and water washing to be neutral, S5, solvent recovery and evaporation to dryness, and obtaining rude unsaponifiable matter; S6, adding ethanol for dissolving, adding activated carbon for adsorption, standing for precipitation, separating out supernate and filtering, and S7, recovering the solvent and evaporating to dryness to obtain the total unsaponifiable matter. The method is advantaged in that three unsaponifiable matter components can be extracted at the same time, less resources and energy are consumed, and the method has good economic benefits.

Description

technical field [0001] The invention relates to a preparation method for extracting total unsaponifiable matter from vegetable oil, belonging to the technical field of food and medicine. Background technique [0002] Unsaponifiables are substances contained in vegetable oils that cannot be saponified with caustic alkali and are insoluble in water. They are important companions of vegetable oils. They mainly include sterols, hydrocarbons, fatty alcohols, tocopherols and pigments. Among them, phytosterols, natural tocopherols, and squalene have various pharmacological effects. They are very precious natural ingredients for both medicine and food, and are also the main components of unsaponifiables. As an important natural pharmaceutical raw material, unsaponifiables have anti-inflammatory, anti-oxidation, anti-ulcer, and cholesterol-lowering effects. At home and abroad, there are oral medicines for dental inflammation, ointments for oral ulcers, and health products for lowerin...
