“…Mahajan et al, (2011) showed that low storage temperature (6°C) could delay the ripening of the Allahabad Safeda cultivar of the guava fruits. Recently, Thapa et al, (2022) observed that applying exogenous Putrescine could delay fruit ripening and maintain phenolic and antioxidant levels. In general, the pattern of phenolic synthesis is comparable to the post-harvest storage to some extent other than the exogenous application of ripening inhibitors.…”

Anatomical (Scanning Electron Microscopy), phenolic (total phenol and total flavonoid), antioxidant (DPPH, FRAP, and ABTS) and analytical profiling (LC and GC-MS) were performed for three different ripening stages (pre-ripe, ripe and over-ripe) of guava. Overall, the antioxidant-phenolic parameters showed a sigmoid pattern of change during the maturation progress of the fruit at room temperature (28±2ºC). Further, the PCA (Principal Component Analysis) established a strong correlation among different phenolic-antioxidant variables studied in this work. Analytical characterization by GC and LC-MS identified 55 (fifty-five) compounds from the guava extract. The PCA revealed a few compounds, namely, Glycine, Gamma Sitosterol, Kaempferol-4'-glucoside, Thiamine, Catechin and n-Hexadecanoic acid, could contribute significantly to the ripening process of guava. Finally, it is expected that an in-depth metabolic study of the guava ripening life cycle performed here could lead to the future development of highly stable fruit varies, with extended post-harvest shelf life at room temperature.

Anatomical (Scanning Electron Microscopy), phenolic (total phenol and total flavonoid), antioxidant (DPPH, FRAP, and ABTS) and analytical profiling (LC-MS and GC-MS) were performed for three different ripening stages (pre-ripe, ripe and over-ripe) of guava with the hydro-methanolic extraction technique. Overall, the antioxidant-phenolic parameters showed a sigmoid pattern of change during the maturation progress of the fruit at room temperature (28±2ºC). Further, the multivariate PCA (Principal Component Analysis) established a strong correlation among different phenolic-antioxidant variables studied in this work. Analytical characterization by GC and LC-MS identified 55 (fifty-five) compounds from the guava extract. The PCA revealed a few compounds, namely, Glycine, Gamma Sitosterol, Kaempferol-4'-glucoside, Thiamine, Catechin and n-Hexadecanoic acid, could contribute significantly to the ripening process of guava.
