Formulasi Sereal Susu Berbahan Baku Sorgum sebagai Pangan Sarapan

Abstract

Sorghum can be used as a basic ingredient in developing ready to eat cereals. The general aim of this study was to develop cereal milks based beverages with sorghum as a main ingredient. The materials used to make cereal milk sorghum were milk powder, sorghum flour, sugar, cocoa powder, vanillin powder, and salt. This study covered two stages of experiment, i.e. preliminary and main experiments. The objective of preliminary study was to produce sorghum flour that can be rehydrated and has good characteristics. Flour that can be rehydrated known as pragelatinized flour. Pragelatinized sorghum flour can be achieved by studying the comparison of the amount of water added in the cooking stage that studied in the preliminary experiment. The ratio of coarse sorghum flour and water (w/v) tested were 1 : 2.5, 1 : 3, 1 : 3.5, 1 : 4, 1 : 4.5. The physical properties of the products resulted such as yield, water solubility index, and the rehydration time were analyzed. Based on these test results, the ratio of flour and water to be used in the main study was 1 : 4. The main study aimed to get a cereal milk formula that was suitable and acceptable by consumers. Variables observed on the main research in determining the optimum formulation of cereal milk were the amount of pragelatinized sorghum flour and milk powder added. The organoleptic test conducted showed that the formulation with a ratio of milk and pragelatinized sorghum flour 3 : 7 was chosen. Based on proximate analysis, the chosen formula contain (dry basis) 5.82% moisture content, 5.87% fat, 8.16% protein, 2.73% ash, and 83.24% carbohydrate. Chosen formula also contain 14.76% dietary fibre and total phenolic compound 3.28 mg GAE (Gallic Acid Equivalent)/ g product. Financial analysis that has been done shows milk cereal product development is feasible.
