Aplikasi Edible Coating Lidah Buaya dan Suhu Penyimpanan untuk Menjaga Mutu Salak Pondoh (Salacca edulis Reinw.) Terolah Minimal.

Abstract

Application of edible coating and storage temperature are common to maintain fruit’s quality. A source that can be used as edible coating is aloe vera which contains antimicrobial substance. Unfortunately extra effort is needed to prepare aloe vera to be edible coating (peeling, crushing, and filtering) that causes difficulties in application. Formulation of aloe vera edible coating in powder form could ease the application. This research aimed to know the effect of spray drying process on aloe vera edible coating characteristics and its effectiveness to maintain minimally processed salak pondoh. Furtheremore, this research aimed to get information about the effect of aloe vera edible coating and storage temperature on minimally processed salak pondoh (Salacca edulis Reinw.). Fruits quality parameters in this research were firmness, weight loss, percentage of damage, and visual changes. Statistical analysis used was Completely Randomized Design with twice replications. The result showed that spray drying process decreased aloe vera edible coating viscosity, total soluble solid (TSS), and titratable acidity, while its pH value increased. Aloe vera edible coating color changed to be yellowish from smooth green. Furtheremore storage temperature gave significant (α=0.01) effect on all parameters, while aloe vera edible coating did not give significant effect on all parameters analyzed, but uncoated fruits were contaminated by molds sooner than coated ones.
