Abstract

This study aimed to determine effect of variations in pressing time and pressing pressure on characteristics of generic nata de coco. This study used a factorial randomized group design consisting of variations in pressing time (A1=4 hours, A2=8 hours, A3=12 hours) and pressing pressure (B1=22,73 kg/m2, B2=34,09 kg/m2, B3= 45,45kg/m2, B4=56,82 kg/m2). Each treatment was repeated 3 times. Parameters observed included moisture content, weight loss, acidity (pH), water absorption, degree of development during rehydration, texture analysis using a texture analyzer and pair discrimination test. The results showed that pressing time had a significant effect on weight loss, water absorption, degree of development during rehydration, and texture. Pressing pressure had a significant effect on moisture content, weight loss, water absorption, degree of development during rehydration, and texture. The interaction between spinner time and drying time had a significant effect on weight loss, water absorption and texture. The best results were obtained in the A1B3 treatment (pressing time 4 hours and pressing pressure 45,45kg/m2) with a weight loss of 80.70%, water absorption 76.66%, degree of development 53.33%, texture before rehydration 1.00 gf and after rehydration 2.37 gf, and organoleptically not different from the control.
