Data for indicating the effects of different treatments, (this include treatments with extracts) on the enzymatic browning fresh cut apples and potatoes that were stored at different temperatures for 5 days. The colour changes in terms of Lab values, Browning score and Browning Index were determined  for the different treatments.

Liquid chromatography-mass spectrometry (LCMS) results show the indication of the bioactive compounds present within the Carica papaya extracts.

Microbial screening tests shows that the extracts were active against bacteria and not yeast strains. Additionally, the gram positive Listeria monocytogenes was more susceptible than gram positive Escherichia coli.
