Postharvest loss caused by biochemical changes in fruits resulted in to number of
problems that lead to poor quality and quantity of the products. Ethylene gas and
respiration are the most notable reason why the climacteric fruits continuously deteriorate
after harvest. To be able to control the deterioration of climacteric fruits, isolation of
biopolymers from the agricultural waste of crabs and the active antioxidant from the
coffee was studied. The spectra generated from the FTIR analysis of extracted crab shell
gave the conclusion that the sample is rich in Chitin, as also indicated in the instrument’s
library. The DPPH Scavenging Activity of Robusta silver skin was 76.02% ± 0.11, and
Total Phenolic Content of 589.59 mg GAE/g. The safety of the coating was tested
through Yeast and Molds Analysis with 8 x 10 CFU/g. The effectivity and acceptability
of coating when applied to tomato was tested using Sensory Evaluation using
Quantitative Descriptive Analysis, the remarks obtained at day 21 after application was
p-value = 0.0262, significantly different from the untreated sample.
