CLARIFIED NEEM OIL AND METHODS OF PRODUCING.

摘要

A clarified neem oil having a cloud point below 13 degree C exhibits reeduced phytotoxicity. Treatment of crude neem oil with a dilute aqueous basic solution or with an enzyme having lipid-degrading activity yields a clarified neem oil having acceptably low phytotoxicity. The methods are advantageous because they reduce or eliminate the waste stream of waxy byproduct generated using existing methods for clarifying crude neem oil.
