| Abstract: | Snap beans were coated with edible chitosan and carboxymethyl chitosan and then compared the physiology and sense quality of each group to select the better edible coating. The result showed that coated snap beans had lower respiration intensity, polyphenol oxidase and peroxidase activity and the content of malondialdehyde than the control groups during the storage. N,O-carboxymethyl chitosan-based coatings were much superior in extension the life of snap beans. |
| Keywords: | snap bean(Phaseolus vulgaris L ) chitosan N O-carboxymethyl chitosan edible coatings |
