Embodiment
The present invention provides a kind of preparation method of dried orange peel extracts, the dried orange peel extracts prepared and application, to make the present invention
Purpose, technical scheme and effect it is clearer, clear and definite, the present invention is described in more detail below.It should be appreciated that this place
The specific embodiment of description only to explain the present invention, is not intended to limit the present invention.
Aurantiamarin is the main active substances in dried orange peel, and the present invention is using the content of aurantiamarin in measurement dried orange peel as evaluation
The quality standard of dried orange peel extraction efficiency and dried orange peel extracts.
One aspect of the present invention provides a kind of method for preparing dried orange peel extracts, including using dried orange peel as raw material, using cellulose
Enzyme and pectase joint enzymolysis prepare dried orange peel extracts.
In one embodiment of the invention, the total amount of the cellulase and pectase accounts for the 2.5- of dried orange peel dosage
4.0%.
In one embodiment of the invention, the proportioning of the cellulase and pectase is 1:2-6.
In one embodiment of the invention, comprise the following steps：
Dried orange peel adds water to be warming up to 50-60 DEG C, and regulation solution ph is 3.0-3.5, then adds the cellulose of special ratios
Enzyme and pectase, enzyme digestion reaction is carried out, the reaction time is 2-3 hours, and the dried orange peel after enzymolysis is made；
After the completion of the enzyme digestion reaction, ethanol solution is added into the dried orange peel after enzymolysis, is warming up to 80-90 DEG C, carries out alcohol
Reaction is proposed, the reaction time is 2-3 hours, is filtered, concentration, dries obtained dried orange peel extracts.
In one embodiment of the invention, the dried orange peel needs to first pass through pulverization process.It should be understood that the crushing
Method can be crushed using those skilled in the art's conventional method, such as pulverizer etc..
In one embodiment of the invention, the proportioning of the dried orange peel and water is 1:8-10.This proportioning is that inventor passes through
Many experiments are obtained, if because the proportioning of dried orange peel and water is too low, cellulase and pectase can not be thoroughly dispersed in water, are influenceed
Contact of the enzyme with dried orange peel, causes the yield of aurantiamarin to reduce.But too high proportioning can dilute the useful effect concentration of enzyme, drop again
The catalytic activity of low enzyme, so as to reduce the yield of aurantiamarin.Content (mg)/dried orange peel of yield=aurantiamarin of the aurantiamarin
Quality (mg) × 100%.
In one embodiment of the invention, the heating is heated up using steam, is warming up to 50-60 DEG C.Enzyme digestion reaction has
Suitable reaction temperature, temperature is too low, and enzyme activity is relatively low, it is impossible to gives full play to effect of enzymolysis.But temperature is too high will
