Mochi with Soy Flour Substitution. Essay. Under the guidance of Distya Riski Hapsari
and Titi Rohmayanti.
Mochi is a typical Japanese cake made from white glutinous rice flour, round
in shape, semi-moist, high in carbohydrates, low in protein. To increase the nutritional
value of protein, it is necessary to add ingredients that contain high protein. This study
aims to make mochi with soy flour substitution to increase the nutritional value of
protein. This study used a completely randomized design (CRD) with two factors, the
first factor was the ratio of white glutinous rice flour and soybean flour 95:5, 90:10 and
85:15. The second factor is the difference in steaming time of 10 minutes, 15 minutes
and 20 minutes. Analysis of the data used for the organoleptic test is frequency
distribution statistics, while for the chemical test using variance (ANOVA) with
Duncan's follow-up test, 95% confidence interval. Mochi was selected based on
hedonic results and protein content, namely the treatment of white glutinous rice flour
85%: soybean flour 15%, steaming time 20 minutes, with sensory quality test results
showing The color of white mochi is slightly yellowish, has a slightly unpleasant
aroma, slightly soy taste and chewy texture, the hedonic test has the attribute values of
color, aroma, taste, texture and overall towards liking. The results of the chemical test
of the selected mochi were 10.72% protein content, 39.44% water content, 0.91% ash
content, 1.1% fat content, 47.38% carbohydrate content.
