【摘要】 以优质南果梨为试材,着重研究了南果梨采摘后在常温条件下2~26天内的可溶性固形物、可溶性糖、可滴定酸以及糖酸比变化过程,发现在这段时间内南果梨的上述指标在后熟期内(果实采摘后2~18天内)升高,在腐败期(果实采摘后18~26天内)下降,南果梨糖酸比为27左右,属品质极佳的梨品种。通过测定发现,南果梨氨基酸含量较高,尤其是人体必需氨基酸含量丰富。更多还原

【Abstract】 The top quality nanguo pear from datun of haicheng city was used as materials. During 2~26 days, the contents of soluble solids, soluble sugar and sugar-acid ratio in nanguo pear rised in the ripening process (2~18 days after plucking) and lowered in the corrupting process (18~26 days after plucking), the sugar-acid ratio of nanguo pear is about 27, so its quality is very good; nanguo pear’s total content of amino acids, special the content of essential amino acids are very high.更多还原
