摘　　要：Quality analysis was performed to major cultivars, ‘Hongxin pomelo’ and ‘Wuzi pomelo＇ with uniform maturity. Total soluble solid （TSS）, titratable acid, vita- min C, juice yield, edible rate, single-fruit weight and pesticide residues of the 2 cultivars were detected. The results showed that： the TSS contents of ‘Hongxin pomelo＇ and ‘Wuzi pomelo＇ were in the range of 8%-12%, the vitamin C contents were in the range of 0.3-0.6 g/L, the juice yields were in the range of 56%-68%, the edible rates were in the range of 52%-68%, and the single-fruit weights were in the range of 1-2.5 kg. The titratable acid content was higher in ‘Hongxin pomelo＇ than in ‘Wuzi pomelo＇. Only Dursban and imidacloprid were detected at low con- centrations in pericarp, and the residues of the 3 pesticides were all lower than their detection limits. Therefore, honey pomelo produced in Hainan all could be ate safely.选择成熟度一致的海南主栽蜜柚品种‘红心蜜柚’与‘无籽蜜柚’进行品质分析。分别检测其可溶性固形物(TSS)、可滴定酸、维生素C、出汁率、可食率、单果重、农药残留。结果表明:‘红心蜜柚’与‘无籽蜜柚’TSS含量在8%~12%之间;维生素C含量在0.3-0.6 g/L之间;出汁率在56%-68%之间;可食率在52%~68%之间;单果重在1 kg^2.5 kg之间。两个品种的品质差别主要在可滴定酸上,且‘红心蜜柚’可滴定酸略高于‘无籽蜜柚’。仅在2个品种蜜柚果皮中检测出低浓度的毒死蜱和吡虫啉残留,果肉中7种农药残留均低于检出限,因此在海南境内生产的蜜柚均可安全食用。
