Abstract

Muffin is a wheat flour-based snack with gluten content and high glycemic index, so substitution is needed to reduce the impact of excess consumption on health. The ingredients used are purple sweet potato and red bean which have high content of energy, carbohydrates, protein and low GI. The study aimed to determine the effect of substituting wheat flour with sweet potato flour and red bean flour on the nutritional value of muffins. This was an experimental study with a single-factor completely randomized design (CRD) with one control group and three treatment groups with the proportion of wheat flour: purple sweet potato flour: red bean flour namely 100:0:0 (P0), 30:20:50 (P1), 30:35:35 (P2), dan 30:50:20 (P3). They were repeated 3 times.  The results showed that there was an effect of wheat flour substitution with sweet potato flour and red bean flour on the nutritional value of muffins (p<0.001). The highest average nutritional value of each treatment is water content P3 (34.45%), ash content P3 (3.06%), protein P1 (9.92%), fat P1 (9.39%), carbohydrate P3 (44.67%), and energy P1 (294.23 kcal). The nutritional value of 50g muffins is in accordance with the quality standards according to SNI and the standard requirements for children, but the fat content is above the standard if it is consumed as snacks for DM patients, therefore it needs to reformulate to fulfill the standard.

Abstract

Diabetes Mellitus is a metabolic disorder marked by hyperglycemia resulting from the body's failure to synthesize insulin. Nutritional therapy is effective in controlling glucose levels by providing low glycemic index and high in antioxidant foods, including sweet potatoes and red beans. The primary objective of this study was to elucidate the influence of wheat flour replacement with composite flour consisting of sweet potato and red bean flour on anthocyanin content and the sensory preferences of muffins. A single-factor completely randomized approach was used in this experimental investigation. The treatment involved substituting wheat flour with a composite flour consisting of sweet potato and red bean flours, in the following ratios: 30:20:50 (F1), 30:35:35 (F2), 30:50:20 (F3), and 100:0:0 (F0, control). Anthocyanin content was analyzed using the differential pH method, while sensory preferences were evaluated by 30 semi-trained panelists using a hedonic scale test. The results showed that substituting wheat flour with composite flour high in sweet potato content increased anthocyanin levels. However, the substitution of wheat flour generally reduced the overall sensory preference for muffins. Despite this, formulations with a higher proportion of sweet potato flour improved the preference scores. In conclusion, the substitution of wheat flour with composite flour rich in sweet potato increased anthocyanin content and improved sensory preferences for color, aroma, and taste in muffins
