KAJIAN ANTIBROWNING EDIBLE COATING CMC DIPERKAYA MINYAK ATSIRI LEMON DAN DAUN SIRIH PADA FRESH-CUT APEL MANALAGI (Malus sylvestris Mill)
Abstract
This study aimed to examine the ability of edible coating CMC combined with lemon and betel leaf essential oils in inhibiting browning and assessed physiological browning activity of Manalagi-apples fresh-cut. The research method used was an experimental method in factorial with two factors arranged in a Completely Randomized Design (CRD). The first factor was CMC concentration consist of 2 levels, which were 1% and 1.5%. The second factor was concentration of essential oils consist of 3 levels, which were 0%, betel leaf 0.1%, lemon 2%. The results showed that the addition of lemon essential oil 2% at CMC 1.5% was the best treatment because it was able to suppress PPO and POD enzymes. Nevertheless, the treatment of CMC 1.5% without the addition of essential oils can inhibit browning on the visual of Manalagi-apples fresh-cut.
