Description
Technical field
The invention belongs to edible oil preparing technical field, be specifically related to a kind of supercritical CO of Sunset Abelmoschus Root oil
2extracting process.
Background technology
Sunset Abelmoschus Root (
abelmoschus manihot L.Medic.), have another name called gumbo, leopard eyes flower, despot's day umbrella, cotton wormwood artemisia, be the annual or perennial sturdy upright herbaceous plant of Malvaceae Abelmoschus.Being used as medicine with root, leaf, flower and seed, can be used for clearing heat and detoxicatingly, moisturize laxation, is a kind of Chinese medicinal materials that the field of Chinese medicines is comparatively conventional.Now there are some researches show, high with fat fat content in yellow hollyhock seed, oil quality is good, has good economic worth and edible, pharmaceutical use, but in prior art, there is not yet the comparatively suitable method of squeezing Sunset Abelmoschus Root oil.
About grease what produce general employing is mainly milling process and solvent extraction method.Generally speaking, it is interior compared with the nutrition of horn of plenty that milling process has retained oil plant, and pollute without chemical solvents, thereby be considered to the safest preparation method, but because milling process exists the defect that oil yield is low, thereby in actual production, be subject to restriction largely.Solvent extraction method is generally to adopt solvent oil (No. six petroleum naphthas) glyceride stock to be carried out after abundant immersion to high temperature extraction, then pass through " six de-" technique (degreasing, come unstuck, dehydration, decolouring, deodorization, depickling) and process, its maximum feature is that oil yield is high, production cost is low.But solvent extraction method exists the defect of dissolvent residual, and production technique is comparatively complicated, thereby is subject to restriction to a certain extent in reality is promoted.
In grease extractive technique, also has a kind of noteworthy aqueous enzymatic method.It is in Mechanical Crushing ground foundation that aqueous enzymatic method is carried oil tech, adopt enzyme (comprising cellulase, polygalacturonase, amylase, proteolytic enzyme etc.) to act on oil plant, make grease be easy to discharge from oil plant solid, then utilize non-oil component (albumen and carbohydrate) to oil and the avidity difference of water, utilize profit proportion difference simultaneously and oil is separated with non-oil component.Compared with traditional technology, it has significant advantage at aspects such as energy consumption, environment and safety and sanitation, is considered to the oil tech of carrying of a kind of " green, environmental protection ".But because this technique is still in the experiment stage of fumbling, the actual utilization and extention of distance still has one section of larger distance.
Supercritical CO in recent years
2abstraction technique has been because its extraction efficiency is high, obtained promoting comparatively widely without advantages such as organic contamination, security height, but in prior art, there is not yet about supercritical CO
2be used for the correlative study report of the comparatively detailed industrial applications that extracts Sunset Abelmoschus Root oil.
Summary of the invention
