Abstract：
This article examined the effect of geographical (different climate conditions) and floral origins on some quality parameters of honey including the activity of diastase enzyme. Moreover, some non-quality parameters were investigated such as the pH, fructose, glucose, ratio of fructose/glucose and invertase. The honey samples were collected from Asir (cold climate) and Jazan (hot climate) regions at the southwestern part of Saudi Arabia. The geographical origin significantly affected the mean value moisture of the Acacia honey (p-value = 0.02), conductivity of the polyfloral honey (p-value = 0.03), sucrose of the Acacia honey (p-value = 0.02), diastase activity of the Acacia (p-value = 0.001), Ziziphus (p-value = 0.046) and polyfloral honey (p-value ≤ 0.001), fructose of the Acacia honey (p-value = 0.01), glucose of the Ziziphus honey (p-value = 0.03), fructose/ glucose ratio of the Ziziphus honey (p-value = 0.035), and invertase activity of the polyfloral honey (p-value ≤ 0.001). Regarding the effect of the floral origin of the honey from Asir region, the sucrose percentage of the Acacia honey was significantly more than that of the polyfloral honey (p- value = 0.003), the diastase activity of the Acacia honey was significantly more than its activity in the Ziziphus honey (p- value = 0.044), glucose percentage of the Ziziphus honey was significantly more the glucose percentage of the Acacia honey (p-value = 0.009) and the fructose/ glucose ratio of the Ziziphus honey was significantly more than that of the Acacia and polyforal honeys (p-value = 0.011 and p-value = 0.045, respectively). Concerning the significant effects of the floral origin on the quality parameters of the honey samples from Jazan region, the moisture of the Ziziphus honey was significantly increased when compared to the moisture of the Acacia honey (p-value = 0.038), the acidity of the polfloral honey was significantly more than the acidity of the Acacia honey (p-value = 0.049), the sum of fructose and glucose of the polyfloral honey was significantly increased compared to that of the Acacia honey (p-value = 0.015), the pH of the Ziziphus hiney was significantly more than the pH of the polyfloral honey (0.011) and the fructose of the polfloral honey was significantly more than that of the Acacia honey (p-value = 0.031). The effect of the geographical origin of the honey samples on their quality parameters depends on their floral origin and the effect of their floral origin differs according to their geographical origin. This article suggests considering collectively the geographical and floral origins effect when developing honey standards. However, the Codex standards for honey started considering this issue when it changed the standard concentration of HMF in honey from not more than 80-40 mg/Kg for honeys from cold climate and 80 mg/Kg for honeys from hot climates.
摘要：
本文研究了地理（不同气候条件）和花卉来源对蜂蜜某些质量参数的影响，包括淀粉酶的活性。此外，研究了一些非质量参数，如pH，果糖,葡萄糖，果糖/葡萄糖和转化酶的比例。蜂蜜样品是从沙特阿拉伯西南部的Asir（寒冷气候）和Jazan（炎热气候）地区收集的。地理来源显着影响相思蜂蜜的平均值水分（p值=0.02），多花蜂蜜的电导率（p值=0.03），阿拉伯胶蜂蜜的蔗糖（p值=0.02），相思的淀粉酶活性（p值=0.001），Ziziphus（p值=0.046）和多花蜂蜜（p值≤0.001），金合欢蜂蜜的果糖（p值=0.01），Ziziphus蜂蜜的葡萄糖（p值=0.03），Ziziphus蜂蜜的果糖/葡萄糖比（p值=0.035），和多花蜂蜜的转化酶活性（p值≤0.001）。关于阿西尔地区蜂蜜的花卉来源的影响，金合欢蜂蜜的蔗糖百分比显着高于多花蜂蜜（p值=0.003），相思树蜂蜜的淀粉酶活性明显高于其在Ziziphus蜂蜜中的活性（p值=0.044），Ziziphus蜂蜜的葡萄糖百分比显着高于金合欢蜂蜜的葡萄糖百分比（p值=0.009），并且Ziziphus蜂蜜的果糖/葡萄糖比率显着高于金合欢和金合欢蜂蜜（p值分别为0.011和p值=0.045）。关于花源对Jazan地区蜂蜜样品质量参数的显着影响，与金合欢蜂蜜的水分相比，Ziziphus蜂蜜的水分显着增加（p值=0.038），花粉蜂蜜的酸度明显高于相思蜂蜜的酸度（p值=0.049），与相思蜂蜜相比，多花蜂蜜的果糖和葡萄糖的总和显着增加（p值=0.015），Ziziphushiney的pH值明显高于多花蜂蜜的pH值（0.011），而多花蜂蜜的果糖明显高于金合欢蜂蜜（p值=0.031）。蜂蜜样品的地理来源对其质量参数的影响取决于它们的花来源,并且它们的花来源的影响根据它们的地理来源而不同。本文建议在制定蜂蜜标准时共同考虑地理和花卉来源的影响。然而,当食品法典标准将蜂蜜中HMF的标准浓度从寒冷气候下的蜂蜜的标准浓度从不超过80-40mg/Kg到炎热气候下的蜂蜜的标准浓度80mg/Kg时，它开始考虑这个问题。
