In this study, comb and industrially processed honey samples collected from Bonga forest were investigated in relation to Melissopalynology and enzyme content, antioxidant and physicochemical properties. Melissopalynology categorized honey samples as and honey. The physicochemical properties of the honey were determined using the Association of Official Analytical Chemists (AOAC) and International Honey Commission (IHC) methods. The enzymatic and antioxidant properties of honey were evaluated using the spectrophotometric method. The highest enzyme activity was observed in comb honey (diastase = 7.44 ± 0.13°Schade and invertase = 13.97 ± 0.2 Invertase number (IN). processed honey exhibited the highest values in flavonoids (83.36 ± 1.65 mg Catechin equivalents (CEQ)/100g)), Ferric reducing antioxidant power (FRAP) (69.94 ± 1.0 mg Ascorbic acid equivalents (AAE)/100g), and Inhibitory Concentration (IC) (136.3 ± 0.00 mg/ml), while comb honey had stronger 1,1-diphenyl-2-picrylhydrazyl radical scavenging (DPPH) (49.47 ± 0.00%) activity. The principal component analysis revealed that enzymes can be associated with comb honey, and antioxidants with processed honey. Thus, comb and processed honey can be differentiated based on the enzyme level, and and honey can be identified using pollen analysis.
在本研究中,对从邦加森林采集的蜂巢蜜和工业加工蜂蜜样本进行了与蜂蜜花粉学、酶含量、抗氧化和物理化学性质相关的调查。蜂蜜花粉学将蜂蜜样本归类为[具体类别1]和[具体类别2]蜂蜜。使用美国官方分析化学家协会(AOAC)和国际蜂蜜委员会(IHC)的方法测定蜂蜜的物理化学性质。采用分光光度法评估蜂蜜的酶活性和抗氧化性能。在[具体蜂巢蜜类型]蜂巢蜜中观察到最高的酶活性(淀粉酶 = 7.44 ± 0.13°施德单位,转化酶 = 13.97 ± 0.2转化酶值(IN))。加工蜂蜜在黄酮类化合物(83.36 ± 1.65毫克儿茶素当量(CEQ)/100克)、铁还原抗氧化能力(FRAP)(69.94 ± 1.0毫克抗坏血酸当量(AAE)/100克)和抑制浓度(IC)(136.3 ± 0.00毫克/毫升)方面表现出最高值,而[具体蜂巢蜜类型]蜂巢蜜具有更强的1,1 - 二苯基 - 2 - 苦基肼自由基清除(DPPH)(49.47 ± 0.00%)活性。主成分分析表明,酶与蜂巢蜜相关,抗氧化剂与加工蜂蜜相关。因此,蜂巢蜜和加工蜂蜜可以根据酶水平进行区分,并且[具体类别1]和[具体类别2]蜂蜜可以通过花粉分析来鉴定。
