Dissertation note: College of Industrial Technology.-- Bachelor of science in food technology: Technological University of the Philippines, 2025. Summary: The study aims to develop an edible coating solution from dragon fruit peel, which can extend the shelf life of mango commodities. The research involved various formulations and processes, and the results showed that the edible coating solution extended mango's shelf life. The peel and pectin's moisture analysis are <10. FTIR analysis confirmed its presence of pectin while pectin identification was done in pure dragon fruit peel which amounted 11.68%. The product's pH range was found to be appropriate for a coating solution (2.54-2.56), and the coating adhered to the mango peel through microscope observation. The product also showed promising results in terms of titratable acidity, soluble solids, color, and texture. Qualitative evaluation showed that government regulations and widespread knowledge of the innovation took time. For QDA the evaluation showed that mango coated (day 4 and day 8) was significantly different from uncoated (day 4) mango. Overall, the study validates the safety, quality, and potential of the edible coating solution for post-harvest issues.

The study aims to develop an edible coating solution from dragon fruit peel, which can
extend the shelf life of mango commodities. The research involved various formulations
and processes, and the results showed that the edible coating solution extended mango's
shelf life. The peel and pectin's moisture analysis are <10. FTIR analysis confirmed its
presence of pectin while pectin identification was done in pure dragon fruit peel which
amounted 11.68%. The product's pH range was found to be appropriate for a coating
solution (2.54-2.56), and the coating adhered to the mango peel through microscope
observation. The product also showed promising results in terms of titratable acidity,
soluble solids, color, and texture. Qualitative evaluation showed that government
regulations and widespread knowledge of the innovation took time. For QDA the
evaluation showed that mango coated (day 4 and day 8) was significantly different from
uncoated (day 4) mango. Overall, the study validates the safety, quality, and potential of
the edible coating solution for post-harvest issues.
