Abstract
Starch which is an abundant and naturally occurring polysaccharide
was used to prepare and evaluate edible biodegradable films. Different
starch sources namely potato starch (PS), corn starch (CS) and oxidized
corn starch (OCS) were used. The formed films were characterized by
physical, mechanical and physiochemical properties determination. Films
solutions were evaluated as edible coatings for maintenance of quality
and extending shelf life of fruits.
The results revealed that coatings prepared from 5% PS, and 2.5%
CS at PH 5 were the best among all used coatings as it extended shelf-life
of apple slices for 17 days and strawberries halves for 9 days. Coatings
prepared from 5% CS, and 2.5% OCS at PH 5 extended shelf-life of
strawberries whole fruits for 13 days. While coatings prepared from 5%
PS and 5% CS at PH 5 were the best coatings for potato balls extended
shelf-life for 9 days.
