Abstract

The development of gluten-free brownies with purple yam paste and mocaf is an alternative for individuals who avoid consuming gluten. This study aims to determine the effect of the ratio of purple yam paste and mocaf on the characteristics of brownies. A Randomized Block Design was used with six treatment levels of purple yam paste to mocaf ratios: 0:100, 15:85, 30:70, 45:55, 60:40, and 75:25. Each treatment was replicated three times. The data obtained were analyzed using Analysis of Variance. If a significant effect was found, the analysis was continued using Duncan new Multiple Range Test (DnMRT) at the 5% level. The results showed that the ratio of purple yam paste to mocaf significantly affected the texture, color, and the hedonic organoleptic qualities of texture and color. The best treatment was the 75:25 ratio which resulted in a texture force of 105.5 N, water content of 20.16%, and color values of L* 37.1 a* 7.8 b* -2.9. Organoleptic scores for this treatment were: texture 3.48 (rather soft), color 4.40 (purple), taste 4.00 (like), overall acceptance 4.04 (like). However, texture and overall acceptance were lower than commercial brownies. The nutritional composition of this treatment included an ash content of 1.42%, protein content of 4.82%, fat content of 29.12%, and carbohydrate of 44.49%.

Abstract

Tempoyak, a traditional fermented food derived from durian (Durio zibethinus), which holds considerable cultural, nutritional, and health significance, and plays an important role in Jambi’s distinctive culinary heritage. This product is generally produced through spontaneous fermentation dominated by Lactic Acid Bacteria (LAB), which plays a crucial role in shaping its sensory attributes, texture, and antimicrobial properties. Nevertheless, such traditional fermentation practices often lead to inconsistent product quality due to variability in raw materials, fermentation conditions, and microbial composition. This review provides a comprehensive examination of the integration of modern food technologies aimed at improving the quality, safety, and functional potential of tempoyak, including molecular-based microbial identification, the use of starter cultures and standardized durian raw materials, as well as the application of innovative packaging technologies such as High Pressure Processing (HPP) and vacuum packaging. These approaches are anticipated to ensure more consistent and safe production of tempoyak, while simultaneously enhancing its functional and economic value, thereby reinforcing its recognition as a heritage food with global market potential.
