                                                                                                                                【適用范圍】廣泛用于檢測蜂蜜

                                                                                                                                【檢測原理】不成熟的蜂蜜,含水量高的蜂蜜,加工、儲存不當的蜂蜜以及摻假的蜂蜜,在酵母菌作用下容易發酵產酸,根據蜂蜜酸度可以鑒別蜂蜜是否發酵或摻假, 因此蜂蜜酸度是蜂蜜質量優劣的重要指標. GB18796-2005 蜂蜜標準規定每公斤蜂蜜酸度應小于40 (1mol/L  NaOH)ml/kg,本試劑盒適用于蜂蜜酸度的快速檢測。

                                                                                                                                【規    格】25次。

                                                                                                                                【使用方法】

                                                                                                                                取樣品2.0g于塑料杯中,加入20mL純凈水將其混勻,加入3滴顯色劑,將測定液滴瓶倒置并直立式滴定,應一滴一滴的滴加, 邊加邊搖勻,至出現粉紅色(30秒不褪色)為止,記錄樣品消耗顯色劑的滴數V。

                                                                                                                                【結果判斷】

                                                                                                                                蜂蜜酸度(1mol/L氫氧化鈉)ml /100g=滴數(V)*0.287;

                                                                                                                                1.測定液有腐蝕性,避免與皮膚及粘膜接觸,如誤入眼中,請立即用大量清水沖洗。

                                                                                                                                2.滴定時注意滴瓶的直立性以減少誤差。本方法測定的結果與國家標準規定量或標簽標示量僅1- 2滴之差時,應慎重處理,可送實驗室精確定量。

                                                                                                                                3.本法適用于現場快速檢測,具體結果以法定檢測單位的檢測結果為準。
