Preparation, physicochemical properties, and <i>in vitro</i> digestion characteristics of coconut diacylglycerol oil.

ABSTRACT: Coconut oil (CO), rich in medium-chain fatty acids and lauric acid, has gained popularity for its functional benefits. This study focused on the preparation and analysis of coconut diacylglycerol oil (CO-DAG), exploring its physicochemical properties and in vitro digestion characteristics, providing a theoretical basis for its application in functional oil. Through enzymatic transesterification using Novozym 435, CO-DAG with a DAG content of 54.65 % was obtained under optimal conditions (substrate ratio 1:2.5, reaction time 9.18 h, temperature 65 °C, enzyme dosage 3.60 %). Compared to CO, CO-DAG exhibited a higher acid value and anisidine value but a lower peroxide value. Additionally, CO-DAG demonstrated a reduced lauric acid content. Hazardous substances levels were within accepta
