Plant essence extraction and preparation method thereof

Abstract

The invention relates to the technical field of plant essence extraction, and discloses a plant essence extraction and preparation method. The method comprises the following steps: S1, treating raw material: washing fresh orange peel with clear water, and draining; S2, soaking with lime water: adding the orange peel into the lime water for soaking; S3, rinsing with clear water: rinsing the soaked orange peel with clear water again, and draining; S4, crushing and squeezing: crushing the orange peel, adding NaHCO3 and Na2SO4, and then squeezing; S5, filtering the squeezed liquid; S6, standing: refrigerating the orange peel oil at low temperature, and then separating out upper orange peel oil; and S7, filtering again: filtering the lower layer with filter paper to obtain the orange peel oil essence. According to the plant essence extraction and preparation method, the preparation cost is reduced, the process is simple and reasonable, the product extraction rate is high, the purity is high, a large amount of organic solvents are avoided, the method is non-toxic and purely natural, and the obtained orange peel plant essence oil is good in quality.

Description

technical field [0001] The invention relates to the technical field of plant essence extraction, in particular to a plant essence extraction and preparation method. Background technique [0002] The extraction of plant volatile oil is not only of practical value to the industrial production of spices, food, and daily cosmetics, but also of great significance to human health care. Relaxation, etc., have increasingly attracted the attention of experts and scholars in the fields of medicinal chemistry, pharmacology and analytical chemistry. Plant volatile oil, also known as plant essential oil, is a volatile oily liquid that can be distilled with water vapor, mostly colorless or light yellow, with a special smell (mostly aroma) or pungent taste, generally volatile at room temperature, difficult to Soluble in water, easily soluble in absolute ethanol, ether, chloroform, fatty oil, mainly divided into terpenes, alkanes, olefins, alcohols, esters, carbonyl and carboxyl-containing...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the present invention provides a plant essence extraction and preparation method, which can solve the problem that the orange peel essential oil components obtained by the existing extraction method are not comprehensive, and some active ingredients of the orange peel cannot be extracted, which makes the orange The taste of the peel is missing, which reduces the edible and medicinal value. At the same time, the method for extracting orange oil from the existing orange peel has high cost, low utilization rate of raw materials, complicated process, and high production cost; the present invention sets a plant Essence extraction and preparation methods effectively solve existing technical problems
