Abstract

The utilizing of arenga starch is still limited in its use in the food or non-food industry, because it needs to be dual modified. The dual modification that has been done is acetylation and phosphorylation in various ratios of sodium trimethaphosphate (STMP) and sodium tripolyphosphate (STPP). The objectives of the study was to obtain an concentrations of STMP/STPP (99: 1, b / b) ratio which based on chemical characteristics at phosphate acetylated arenga starches (PAAS). The treatment used in this study consisted of dual modification of acetylation and phosphorylation using at different concentration of STMP / STPP ratio of 2%, 4%, 6%, 8%, 10%, and 12%. Observation parameters were acetyl percent, substitution degree (DS), phosphate content, moisture content, starch content, amylose content and ash content. The results showed that the best concentration of STMP / STPP ratio was 6% because it was produced PAAS with the highest percent acetyl and DS 10.52% and 0.48 respectively. PAAS water content is lower than native arenga starch. Pospor, starch and amylose content have been relatively constant after dual modification. PAAS ash content increases with increasing concentration of STMP / STPP ratio. The dual modification process would improve the chemical properties of the resulting modified starch.

Abstract

This work deals with the effect of banana (sweet plaintain or ‘kepok’ variety) hump flour substituted to wheat flour in the making of noodle, on physical, chemical, and sensory characteristics of noodle.  A completely randomized was employed, with three replicates. Sensory analysis was conducted according to randomized group design. Four proportions of banana hump to wheat flour (10:90, 20:80, 30:70, and 40:60, weight basis) was studied. Results showed that the best physical and chemical characteristics was shown by noodle made from 10:90 proportion of banana hump to wheat flour, with 4.59% water absorption, 0.57% cooking loss, 10.37% water content, 34.21% starch content. However, result of sensory analysis suggested that the most liked noodle was that made from flour proportion of 20:80 with ‘like’ for colour, ‘like very much’ for aroma, ‘like’ for texture, ‘like’ for taste, and ‘like’ for overall preference
