Kajian Pembuatan Beras Analog Berbasis Tepung Komposit dengan Penambahan Konsentrasi Bubur Rumput Laut (Gracilaria sp.) dan Gliserol Monostearat

Abstract

Rice consumption is estimated to increase along with the increase in
population every year. Analog rice is one alternative to functional food diversification
and was expected to help reduce people's dependence on rice consumption. The addition
of seaweed and glycerol monostearate in the study was intended to improve the shape of
rice grains from previous studies which were sticky so that the shape of the rice was
lost, enriching antioxidants and fiber from analog rice. The purpose of this study was to
determine the interaction and effect of the addition of seaweed pulp extracts and
glycerol monostearate to analog rice. The design of this study is a factorial randomized
block design (RBD-F). Factor I is seaweed with 3 levels of concentration {1%, 2%, 3%},
factor II is glycerol monostearate with 4 levels of concentration {1%, 2%, 3%, 4%}. The
results of the study the highest value on the water content of the addition of seaweed 3%
by 7.51%; carbohydrate glycerol monostearate level of 1% was 91.78%; the antioxidant
activity of rice and rice in seaweed concentration of 3% by 27.35% and 25.57%; The
highest value of rice fiber and rice in the treatment of Seaweed 3% and GMS 3% by
1.53% and 1.63%. Organoleptic results in the form of appearance (5.33 = interesting),
taste (4.44 = somewhat like), fondness (4.33 = somewhat like), aroma (2.67 = not fishy),
and texture (2.33 = not sticky).
