Compared to the control longans, hydrogen peroxide (H

)-treated longans exhibited higher index of pulp breakdown, higher fruit respiration rate, higher activities of pulp
phosphohexose isomerase
(PGI), succinate dehydrogenase (SDH), cytochrome C oxidase (CCO),
ascorbic acid oxidase
(

) and polyphenol oxidase (PPO), but lower activity of pulp nicotinamide adenine dinucleotide kinase (NADK). H

-treated longans also exhibited lower total activities of pulp glucose-6-phosphate dehydrogenase (G-6-PDH) and 6-phosphogluconate dehydrogenase (6-PGDH), lower levels of pulp NADP(H), but higher levels of pulp NAD(H). These data indicated that H

-stimulated longan pulp breakdown was owing to a decreased proportion of pentose phosphate pathway (PPP), the increased proportions of Embden-Meyerhof-Parnas pathway (EMP), tricarboxylic acid (TCA) cycle and cytochrome pathway (CCP) in total respiratory pathways. These findings further revealed that H

could enhance respiration rate, and thus accelerate pulp breakdown occurrence and shorten the shelf life of longan fruit.
