Karakteristik Fisik, Kimia dan Organoleptik Keripik Simulasi Berbasis Komposit Ubi kayu (Manihot esculenta Crantz )dan Beras (Oryza sativa)

Abstract

This research was aimed to obtain best formula and study the influence of cassava:rice ratio (60:40,70:30,80:20) the cooking methods (baking and frying), cooking temperatures of baking (140°C, 160°C, dan 180°C) and friying (150°C, 160°C, dan 170°C) on the physical, organoleptic, and chemical characteristics of the simulated chips enriched with carrot, cellery, skimed milk, and curry leaf. The best formula of the cassava:ricesimulated chips were studied using completely randomized design with two replicates. The results showed that the simulated chips of 80:20 ratio of cassava:rice baked at 140 ºC for 15 minutes, and the simulated chips with 60:40 ratio of cassava:rice fried at 150 ºC for 2.5 minutes was chosen as the best one. The fried chips has a smoother microstrucutal characteristics than baked chips. In addition, the organoleptic test showed that fried simulated chips was generaly more acceptable than the roasted simulated chips. The acceptability of roasted simulated chips is neutraly acceptable (3,69- 4,14) so it has potentially to be further developed.
