Abstract

The high consumption of fresh fruit encourages the development of studies on safe food coatings, such as hydrocolloid-based edible coatings. In this study, a complex polyelectrolyte based on chitosan (chi) was synthesized and applied as a coating for fresh pineapple. As a cationic polymer, chitosan interacts with anionic polymers, such as carrageenan (crg) and alginate (alg), to form complex polyelectrolyte films without involving crosslinkers. The effect of film coating on the loss of vitamin C and the weight of sliced pineapple at various storage periods was determined. Biodegradability assays and FTIR analysis of films were also studied. The FTIR spectra of the films confirmed the formation of alg-chi and crg-chi complex polyelectrolytes through the interaction of carboxylic groups (alg) and sulfate (chi) with protonated amines from chitosan, at pH 5.28. The alg-chi and crg-chi edible films could maintain the stability of the vitamin C levels and inhibit the weight loss rate in sliced pineapple. The biodegradability test showed that both films had a high % biodegradability. The alg-chi film is more accessible to decompose than the crg-chi film due to the more hydrophilic alg-chi film. Therefore, chitosan-based polyelectrolyte film is an excellent candidate for application in the food coating industry, especially for fresh fruit products.
