چکیده
|
He solubility and mechanical properties of purple sweet potato (psp) starch-based edible films are being investigated. the formulation was prepared using a constant amount of psp starch (4 % w/v) with five different ratios of carrageenan and glycerol (1:1,1.5:0.5,0.5:1.5,0.5:0.5,1:0) which act as gelling agents and plasticizers respectively. psp starch generates 61.79 mg/100 g anthocyanin and retains 16.78 % antioxidant capacity. carrageenan and glycerol (0.5:1.5) ratio shows the highest solubility in water (53.50 ± 0.1085 %) and highest tensile strength (9.1674 ± 0.5399 mpa) with the lowest elongation at break (20.436 ± 2.826 %). © 2016 penerbit utm press. all rights reserved.
