Pengembangan Teknologi Pembuatan Mi Sagu (Metroxylon sagu)

Abstract

Sago (Metroxylon sagu) is one of local food in Indonesia which has the potency to be further developed as raw material for gluten-free noodle (non-wheat noodle). The purpose of this research is to develop an extrusion-based technology for sago noodle production. The addition of a protein sources, i.e. soy flour was done to determine the effect of protein on cooking loss, elongation, hardness, cohesiveness, and adhesiveness of sago noodle. The addition of soy flour with concentrations of 5%, 10%, 15% and 20% has a significant effect in increasing cooking loss, reducing its elongation, hardness, and cohesiveness (p <0:05). Furthermore, sago noodle without the addition of soy flour (F1) and with the addition of 5% soy flour (F2) could decrease hardness while retaining a minimum cooking loss, which is less than corn noodle and commercial spaghetti. F2 contains higher protein, fat, and ash, but lower carbohydrate than F1. Hedonic rating test results showed F1, F2 and corn noodles acceptance were not significantly different in texture attributes (p ≥ 0.05), while the color and flavor attributes of corn noodle has the highest acceptance. The acceptance of F1 and F2 noodle were not significantly different (p ≥ 0.05) on all attributes.
