Abstract:
Garcinia atroviridis fruit and gelatin extracted from Salmo salar skin were utilized to develop gummy jelly product. The gelatin extraction from Salmo salar skin was extracted under different pH (4, 6, and 8) and temperature (50, 60, and 70°C). The mixture design was used to optimize the formulation of gummy jelly with the variation of pectin (0.5–1.5%) and gelatin (8.5-9.5%). Highest yield recovery (6.20±0.09%) was obtained from the extraction at pH 4 and 50°C, while the highest value of bloom strength, viscosity, WAC, and WRC (198.67±4.51 g, 7.7±0.58 cP, 21.03±0.37%, and 148.39±2.36%, respectively) was shown by gelatin extracted at pH 6 and 50°C. The highest score of sensory evaluation in flavor (6.8±1.1), sourness (7.0±1.0), and overall liking (7.0±0.7) were obtained by gummy jelly made with the highest amount of pectin (1.5%) and least amount of gelatin (8.5%). The highest score of texture (7.1±0.5) was obtained by gummy jelly composed by highest amount of gelatin (9.5%) and least amount of pectin (0.5%). Based on the significant attributes, optimized amount of pectin and gelatin were 1.42% and 8.58%. Results on the consumer acceptance shows that there was no correlation in the acceptance and purchase intention of Garcinia atroviridis gummy jelly between consumers with the belief in Islam, Buddhism, and others, while age and occupation of the consumers shows correlation to the acceptance and purchase intention of the product.
