EVALUASI SIFAT FISIK PATI GANYONG (Canna edulis Kerr.) SEBAGAI BAHAN BAKU PEMBUATAN KWETIAW PADA TINGKAT SUBSTITUSI YANG BERBEDA

Abstract

Canna is an alternative carbohydrate sources that have not been developed yet. With a fairly high carbohydrate
content, ganyong can be used as industrial raw materials.The aim of this research was to evaluate physical
properties of canna starch as raw material on kwetiaw production with different substitution level. This
study was conducted using randomized completely design with single factor, the persentation of canna
starch which consist of 5 levels : A = 0%, B = 25%, C = 50%, D = 75% and E = 100%. Experimental data
were subjected to ANOVA test followed by LSD with 1% level of significance. Parameter analyzed were
swelling power, viscosity, freeze-thaw stability (% sineresis) and paste clarity. The result showed that swelling
power, degradation viscosity, freeze-thaw stability and paste clarity were increased with increasing of canna
starch persentation.

Key words: canna starch, kwetiaw, swelling power, viscosity
