since films have to be formulated according to the properties of the fruit to which they have to be applied.
Response surface methodology (RSM) is a statistical tool that is commonly used for optimization studies.
Several studies on the application of RSM in the development of edible coating formulations have proven the effectiveness of this statistical tool.
Study on the development of chitosan- and glycerol-based edible coating using RSM has been able to extend shelf-life and delay ripening of Berangan bananas under ambient conditions. In addition, a study on formu-lating alginate and gellan-based edible coatings with the ability to carry antimicrobial agents for fresh-cut ‘Fuji’ apples was also designed using response surface methodology.
Alginate and gellan-based edible coating formulations were also successfully optimized for application on fresh-cut pineapple.
The objective of this study was to determine the optimum con-centrations of carrageenan and glycerol to be used as edible coating for ‘Eksotika’ papaya using RSM, with firmness and colour compo-nents (L, a and b values) as the response variables
