ANALISIS KARAKTERISTIK KIMIA VIRGIN COCONUT OIL (VCO) DENGAN PENAMBAHAN SARI SERAI (Cymbopogon citratus) SEBAGAI ANTIOKSIDAN ALAMI

Abstract

Research aims to analyze the chemical characteristics (water content, free fatty acid, and peroxide value) of VCO with addition of lemongrass extract and analyze the antioxidant activity of VCO with the addition of lemongrass extract. Research method used was a Completely Randomized Design (CRD) Method consisted of five treatments, each treatment was repeated three times with lemongrass extract addition of 0%, 10%, 12,5%, 15%, and 17,5%. Results showed chemical characteristic of VCO water content of 0,05-0,16%, free fatty acid of 0,11-0,19%, peroxide value of 0,60-0,90 mEq/kg where all values met the VCO quality standards and antioxidant activity exhibiting IC50 values of 66-300 µg/ml categorized from strong to very weak.
