Abstract

It has been analyse that kwetiau adulterated with lard by approximating the sample weight and concentration of n-hexane as a solvent. This study used a Factorial Completely Randomized Design (CRD) with two (2) replications. Factor I is the difference in sample weight (B) consisting of 4 levels, namely: B1 = 50 g, B2 = 60 g, B3 = 70 g and B4 = 80 g. The second factor is the difference in the concentration of n-hexane (N) consisting of 4 levels, namely: N1 = 20%, N2 = 30%, N3 = 40% and N4 = 50%. The parameters observed were: specific gravity and refractive index. The analysis results for Specific gravity: sample weight and n-hexane concentration both had no significant effect (P> 0.05) on both lard and non-lard kwetiau. The interaction between sample weight and n-hexane concentration also had no significant effect (P> 0.05) on both lard and non-lard kwetiau. Refractive index: The sample weight on lard kwetiau had a very significant effect (P <0.01) on the refractive index. The highest refractive index is found in treatment B4 which is 1.786 and the lowest value can be seen in treatment B1 which is 1.668. The concentration of n-hexane in kwetiau lard gave a very significant effect (P <0.01) on the refractive index. The highest refractive index is found in treatment N4 which is 1.755 and the lowest value can be seen in treatment N1 which is 1.683. Treatment interactions had no significant effect (P> 0.05) on the refractive index. Meanwhile, sample weight on kwetiau without lard had a very significant effect (P <0.01) on the refractive index. The highest refractive index is found in treatment B4 which is 1.503 and the lowest value can be seen in treatment B1 which is 1.469. The concentration of n-hexane in kwetiau without lard had a very significant effect (P <0.01) on the refractive index. The highest refractive index is found in treatment N4 which is 1.497 and the lowest value can be seen in treatment N1 which is 1.474.
