Abstract

Purple sweet potato has good prospects as a raw material in the food industry, especially in the form of flour. However, purple sweet potato flour has several weaknesses such as low solubility in water, low water absorption capacity and the gel form is less uniform. The modification of purple cassava flour with pregelanitisation has been developed, but there is a decrease in the level of active components of anthocyanin and its antioxidants. The aim of this research is to find out the right pregelatinization temperature and time to produce the best modified purple sweet potato flour and to find out the ratio of modified purple sweet potato flour and moringa leaf flour to produce flakes with the best characteristics. This research was divided into two stages. The first stage was that the purple sweet potato was pregelatinized with a steaming temperature of 70oC, 80oC and 90oC and steaming time of 5 minutes, 10 minutes and 15 minutes. The best results from the first stage of research were then applied to the second stage of research, namely the effect of adding Moringa leaf flour to purple sweet potato flakes with several levels, namely 0%, 3%, 6%, 9% and 12%. The results of the first stage of research showed that steaming treatment with a temperature of 70oC and a duration of 5 minutes produced the best modified purple sweet potato flour with yield characteristics of 24.90%, anthocyanin content of 25,65 mg/L, starch content of 63.10%, amylose content of 28.73%, amylopectin content of 34.37%, anthocyanin content 25.62 mg/L, viscosity 2597 cP, water absorption capacity 113.27% and oil absorption capacity 110.68%. Modified purple sweet potato flour with the best treatment is used in making purple sweet potato flakes which is added with flour Moringa leaves. The treatment with the addition of 12% moringa leaf flour produced the best purple sweet potato flakes with yield characteristics of 59.41%, anthocyanin content of 8,02 mg/L, antioxidant activity of 19.31%, and organoleptic tests with characteristics of aroma is liked, slightly bitter and like taste, slightly crunchy and liked texture and the panelists overall acceptance is liked.

Abstract

Red sorghum is a cereal plant that can be utilized as a carbohydrates source with high content of protein and antioxidants activity, but it has anti- nutritional compounds such as tannins. The germination process can improve the physical and chemical properties of materials including protein digestibility and antioxidant activity. This research aims to determine the effects of germination time on physical and chemical properties of red sorghum sprouts flour and determine the ideal germination time to produce red sorghum sprout flour with the highest protein digestibility and antioxidant activity. This study used a Completely Randomized Design with five treatment levels of germination time: 0, 12, 24, 36, and 48 hours, each repeated three times. Parameters observed in this study included water content, protein content, tannin content, protein digestibility, antioxidant activity, and color analysis (L*, a*, b*). The data obtained were analyzed using variance analysis. The results of the research show that the germination time significantly affects protein digestibility, antioxidant activity, protein content, tannin content, and the color parameters lightness, redness, and yellowness of malted red sorghum flour, but does not affects its water content. The ideal germination time of red sorghum based on this research is 48 hours, which produce malted red sorghum flour that contains water content 7.67%, protein content 9,08%, tannin content 0.38%, protein digestibility 79.49%, antioxidant activity (IC50) 147.44 ppm, and color analysis (lightness 74.03, redness 1.60, yellowness 10.67)(yellowish white with a slight red hue).
