Abstract
The present disclosure relates to a method for preparing a subcritical water extract of an almond by-product, and specifically, to a method for extracting polyphenols from almond hulls in high yield using subcritical water extraction. The present disclosure can effectively utilize almond hulls, which is an almond by-product generated during the production and harvest of almonds, and minimize the amount of almond waste, and is environmentally-friendly because polyphenols are extracted using only subcritical water. Additionally, the extraction yield of polyphenols within almond hulls can be improved by performing the extraction under specific conditions.
Claims5
A method for preparing a subcritical water extract of an almond by-product, comprising:
- grinding an almond by-product using a grinder;
- maintaining the induction time, which is the time required for the temperature of an oven inside a subcritical water extractor to become the same as the pre-set temperature of the subcritical water extractor;
- supplying the ground almond by-product to the subcritical water extractor;
- and
- supplying distilled water to the subcritical water extractor and performing subcritical water extraction at a temperature of 130° C. to 150° C. and a pressure of 8 MPa to 12 MPa.
