Conteúdo: | As investigation was carried out into the chemical and sensory assessment of canned satsuma mandarin during long-term storage. The carbonyl compounds as 2,4-dinitrophenyl hydrazones were separated by silica gel TLC. 3-Deoxyglucosone, 3-deonypentosone, 5-hydroxymethyl furtural (HMF) and furtural were identified. The content of HMF as a dominant carbonyl compound increased noticeably during storage at higher temperatures. Canned satsuma mandarin which contained HMF above 50 ug/g gave inferior quality in sensory evaluation. This HMF level was achieved by three to four years storage at ambient temperature. These results demonstrate that HMF is good as a quality index of canned satsuma mandarin. Furthermore, the amount of d-limonene decreased significantly during storage, whereas furtural increased. This result demonstrates that determination of these volatiles is also available for quality assessment.
