| Summary: | The objective of this study was to evaluate the effect of alginate edible coating supplemented with glycerol and brown seaweed extract Sargassum polycystum (A-G-S film) on fresh-cut apples. The result obtained with the formula film A-G-S is the concentration of alginate/ water 1.0%, glycerol 20%, and additional extract 2.0%. The A-G-S film on the surface of fresh-cut apples has the same antioxidant capacity as A-G-As film, using ascorbic acid as an antioxidant. These fresh-cut apples are recommended to be stored at 5±2oC for 12 days with a commercial acceptance ratio (CAR) of 59.57%. The values of WL, TSS/TA, TPC are respectively 16.51±0.52%, 30.80, and 0.63±0.02 mg/g. The film has an average thickness of 7.04 µm, uniform surface, certain ductility, and water vapor transmittance rate (WVTR) of the film 5.31x10-4 g/mm2. |
