Abstract:
The objectives of this study were to 1) study the basic recipe for tortillas flour, 2) study the appropriate amount of Sangyod rice flour in frozen tortillas, 3) study the effect of xanthan gum in tortillas flour recipe from Sangyod rice, and to 4) study the quality of frozen ready-made tortilla flour. It was used to measure texture, color and evaluate sensory quality in terms of appearance, color, aroma, taste, texture and overall liking. Using the method of tasting with a 9-level preference score (9 - Point Hedonic Scale), the results found that all 40 panelists gave their preferences to the 3 basic flour tortilla wrap recipes a significant difference (p≤0.05). The panelists gave Recipe 1 the highest score for overall liking, appearance, and taste, with average scores of 8.13, 8.08, 8.00, 8.03, 7.65, and 8.13, respectively. In terms of the color and odor characteristics of the 3 tortilla flour recipes, the acceptability scores were not different (p≥0.05). Using Sangyod rice flour instead of wheat flour in frozen tortilla products found that the more the amount of Sangyod rice flour was added, the tortilla's brightness (L*) and yellow (b*) values decreased, and on the other hand, the red (a*) values increased according to the increasing amount of Sangyod rice flour. When using tortillas using Sangyod rice flour instead of wheat flour for studying the effects of xanthan gum, compared to the recipe without added xanthan gum, the sensory test found that all 40 testers favored the tortillas that used Sangyod rice flour instead of wheat flour were significantly different in statistics (p≤0.05). The results of the quality study in terms of microbial content of basic tortillas flour and tortillas using Sangyod rice flour instead of wheat flour found that all microorganisms, including yeast and mold, detected in the tortillas flour passed the criteria. Compared to the requirements of community product standards for instant roti (MPC.504/2004). The results of nutritional value analysis was found that the tortillas using Sangyod rice flour instead of 50 percent wheat flour per 100 grams had 399.32 kilocalories of energy, 7.46 grams
of protein, 16.32 grams of fat, 55.65 grams of carbohydrates, 2.6 grams of ash, and 17.97 grams of moisture, which the energy content was higher. However, the protein content was lower than the basic recipe that used wheat flour. As a raw material, wheat flour had a higher amount of gluten protein than Sangyod rice flour.
