Climate variables, made us think about sustainability and green practices to reduce future risk and negative environmental impacts, maintain natural resources, and reduce carbon emissions. Nowadays, using reusable, biodegradable, it can also indicate recycling and manufacturing techniques that reduce pollution. Bagasse is an eco-friendly substitute for conventional packaging sources. Communally origin sugarcane fiber attends more benefits packages for the packaging. In this investigation, we tested the effect of bagasse package (T1), mixed bagasse and polyethylene package (T2), a slice of chitosan put in polyethylene package (T3) and control was commercial polyethylene package (T4) on guava fruit under cold storage. All packaging materials are found to have significant effects on physiological weight loss, chilling injury percentage, titrable acidity, vitamin C content, overall acceptability, and marketability of guava fruits under refrigeration temperature.
