Tiara Amanda Lestari. B1610350. Formulation of Legume Composite Flour on
Manufacture of Elderly Instan Porridge by Tray Drier Method. Supervised by
Tiana Fitrilia and Titi Rohmayanti.
Elderly experiencing health problems due to decreased anatomic and
physiological functions in the digestive system, so that requires food that is easily
digested with sufficient nutritional content. The aim of this research is to
formulate instant porridge from legume flour composite which can meet the
nutritional needs of the elderly and find out the right drying temperature. This
study use Complete Randomized Design by two factorial. The first factor is
instant flour formulations (soybeans, kidney beans, and green beans) with three
treatment levels A1 (21%: 15%: 24%), A2 (18%: 18%: 24%), and A3 (15% :
21%: 24%). The second factor is the difference in drying temperature with two
treatment levels B1 (60?C) and B2 (70?C). Data analysis used variance analysis
(ANOVA) and showed that flour formulation, drying temperature, and interaction
between the two factors affected several physical and chemical properties of
instant porridge. The selected instant porridge is the instant formulation A1B1.
Selected instant porridge has a bulk density of 0.67 g / mL, 4.00 g / g water
absorption, 4.24% water content, 4.59% ash content, 2.98% fat content, 19.5%
protein content, 68.6% carbohydrate content, 14.1% dietary fiber, calcium 518.69
mg / 100 g, and total energy 379.5 Kcal / 100 g. The hedonic test results showed
96.7% of the elderly said they liked the color, 60.0% really liked the aroma,
93.3% liked the taste, and 70% liked the texture.
