Firmness
Generally,fresh-cut produce lose firmness during storage time,and this was also observed with fresh-cut mangoes (Fig.2).Firmness loss in mango has been attributed to the action of pectolytic enzymes, namely polygalacturonase and pectinesterase on the solubilisation of pectic substrates. Firmness loss was higher degerr at low=temperature storage because of the chilling injury.This result was softer than uncoated. WE previously hypothesised that solubility of the hydrophilic mango film might cause diffusion of water to the fruit flesh,resulting in lower firmness.Furthermore, The effect of mango film without MAP on firmness of fresh-cut mango was similar to the effect of MAP alone without coating in this study.This indicates that coating fresh-cut mango with mango film exhibited the similar effect on firmness as MAP regardless of temperature storage.The loss of mango firmness was also found in carboxymethyl cellulose coatings on fresh-cut mango. Additionally, SemperFresh edible coating showed no significant protection of firmness loss in fresh-cut mangoes.Nonetheless,coating fresh-cut mango with mango film might enhance the acceptance by consumers and reduce the loss of ripe mango during the harvest season.
