Response of gac fruit (Momordica cochinchinensis Spreng) to postharvest treatments with storage temperature and 1-MCP

Buanong M., . and Soe Win, . and Kanlayanarat S., . and Wongs-Aree C., . Response of gac fruit (Momordica cochinchinensis Spreng) to postharvest treatments with storage temperature and 1-MCP. pp. 178-189. ISSN 22317546

The effects of various low temperatures and 1-methylcyclopropene (1-MCP) pre-treatments on changes in physical physiological and phytochemical attributes and in antioxidant activity of gac fruit were evaluated during storage. Low temperature regimes including 4 10 and 13C had the greatest impacts on ripening color changes and bioactive compound content of gac fruit compared to control at 25oC. However fruit stored at 4C showed both external and internal chilling injury symptoms starting from day 25 of the storage. Low temperature greatly preserved the reduction of phenolics and antioxidant capacity detected by FRAP (Ferric Reducing Antioxidant Power) during storage. 1-MCP fumigation at 500 nL.L-1 showed slight effect on retarding an increase of ethylene production and on delaying fruit softening during 10C storage. Nevertheless 1-MCP had no effect on changes of peel color phytochemicals and antioxidant activity of gac fruit.

Abstract

The effects of various low temperatures and 1-methylcyclopropene (1-MCP) pre-treatments on changes in physical physiological and phytochemical attributes and in antioxidant activity of gac fruit were evaluated during storage. Low temperature regimes including 4 10 and 13C had the greatest impacts on ripening color changes and bioactive compound content of gac fruit compared to control at 25oC. However fruit stored at 4C showed both external and internal chilling injury symptoms starting from day 25 of the storage. Low temperature greatly preserved the reduction of phenolics and antioxidant capacity detected by FRAP (Ferric Reducing Antioxidant Power) during storage. 1-MCP fumigation at 500 nL.L-1 showed slight effect on retarding an increase of ethylene production and on delaying fruit softening during 10C storage. Nevertheless 1-MCP had no effect on changes of peel color phytochemicals and antioxidant activity of gac fruit.
