Physiology and postharvest conservation of ‘Paluma’ guava under coatings using Jack fruit seed-based starch

Abstract The aim of this work was to evaluate the effect of jackfruit seed starch-based (S) coatings, added to chitosan and alginate on the physiology and maintenance of quality of cold stored ‘Paluma’ guavas, followed by transfer to the room condition. The design was the completely randomized, in...

Description
Summary:Abstract The aim of this work was to evaluate the effect of jackfruit seed starch-based (S) coatings, added to chitosan and alginate on the physiology and maintenance of quality of cold stored ‘Paluma’ guavas, followed by transfer to the room condition. The design was the completely randomized, in a 4x2 factorial scheme, in 4 replications, with 4 coatings (dispersion of S - 4%; S 2% + chitosan - 2% (SC); S - 2% + alginate - 2% (SA); and the uncoated control), in 2 environments (refrigerated (10±2 °C e 80±2% RH) with transfer to room condition (25±3 °C e 75±4% HR)), on the 16th and 20th day of cold storage. The SC and SA coatings were efficient in reducing the respiratory rate in fruits during 10 days at room condition. The SC coating delayed fruit ripening, and maintained firmness and color, with intention of purchasing and appearance higher than the limit of acceptance for another 6 days, following transferring to room condition, at the 16th day of refrigeration.
