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).

Abstract

Abstract Fish nuggets are a popular ready-to-eat food, usually made with wheat flour and cornstarch as fillers and binders. However, the gluten in wheat flour is known to trigger celiac disease, thus encouraging the exploration of alternative flours such as beneng taro flour. This study aims to evaluate the effect of variation in the ratio of beneng taro flour and cornstarch on the physicochemical and sensory characteristics of tuna fish nuggets and to identify the optimal ratio to produce the best nuggets. This study was designed with a simple Complete Random Design (RAL) with the ratio of beneng taro flour and cornstarch (70%:30%, 75%:25%, 80%:20%, 85%:15%, and 90%:10%) as the treatment. The results showed that the treatment significantly affected sensory properties, hardness, ash content, protein content, fat content, and carbohydrate content but did not significantly impact moisture content. The sensory test showed that the tuna fish nuggets that the panelists liked the most were those produced from the formulation of a comparison of beneng taro flour and cornstarch 80%:20% with the average preference value on the color somewhat preferred, and the aroma, taste, texture, and overall acceptance were preferred. This formulation produces tuna fish nuggets with the following characteristics: hardness 8.59 N, moisture content 21.21%, ash content 2.19%, protein content 24.98%, fat content 15.50%, and carbohydrate content 36.12%. These findings indicate that the optimal ratio of beneng taro flour and cornstarch to produce gluten-free tuna fish nuggets with the desired characteristics is 80%:20%.
