Abstract

Background: This project purposes to study the changes of popcorn in texture after 5 storage days, proximate composition, coating ability and consumer acceptance by using different ratio of D-allulose in coating of popcorn. Method: Total 3 formulations, including control (100% sucrose), Formulation 1 (50% sucrose with 50% D-allulose) and Formulation 2 (60% sucrose with 40% D-allulose) were developed to determine the hardness and fractuability of popcorn in 5 days of storage time. Texture analysis, proximate analysis, microbial analysis and sensory evaluation were carried out to identify the physical properties, coating ability and acceptable index of consumer towards popcorn. Results: Moisture content (5.57%), crude fat (18.51%), crude protein (2.93%), crude fiber (1.93%), ash content (0.32%) and carbohydrate (70.94%) were determined for F2. Besides that, F2 gained the highest hardness (4048.649 g force) and fractuability (4354.398) after 5 days of storage. F1 has lowest microbial count with 2.80 x 102 CFU/g for Total Plate Count and 2.0 x 102 CFU/g for Total Yeast and Mold Count. Regarding to coating ability, F2 showed higher coverage of coating. F2 popcorn sample obtained the highest acceptance index of 98% in sensory evaluation by assess six attributes including appearance, aroma, crispiness, sweetness, hardness and overall acceptability. Conclusion: F2 popcorn sample seem to be the optimum composition for popcorn coating in term of storage, coating ability and consumer acceptance. Recommendation: More approaches and techniques need to be explored to investigate the rheology of D-allulose as coating application as well as ways to reduce the production cost of D-allulose in order to produce D-allulose containing product with fair price.
