成熟蜜与非成熟蜜酸度值的检测与研究

Detection and Study of Mature Honey and Non-Mature Honey Acidity Value

本文对同一蜜种蜂蜜进行样品采集和酸度值检测,并对仓储一年的蜂蜜酸度值进行追踪检测,对不同品质蜂蜜酸度值的差别及酸度值随存储时间的变化进行了深入研究。实验可知,成熟蜜酸度值密集区间为5~8 ml/kg,非成熟蜜即水蜜酸度值普遍高于成熟蜜酸度值,且大部分在10 ml/kg以上区间,经过一年仓储后,成熟蜜酸度值升高但绝大部分仍小于10 ml/kg,非成熟的水蜜酸度值升高后已有部分接近甚至高于40 ml/kg,酸败明显。根据我国相关行业标准要求,正常蜂蜜酸度值应小于40 ml/kg,通过本研究可知,成熟蜜与非成熟蜜初始酸度值均可在合理范围内,但随时间延长,蜂蜜酸度值均呈现升高趋势,成熟蜜酸度值变化不大,而非成熟蜜酸度值升高变化较显著,由此可知非成熟蜜不利于甚至无法正常保存,经过一定时间的存储,其酸度值会自然升高超出合理范围,所以当蜂蜜酸度值高到一定数值时,说明很可能是非成熟蜜即水蜜或已发生酸败的变质蜜。

In this paper, the samples of the same kind of honey were collected and the acidity of the honey was detected, and the acidity of the honey stored for one year was tracked;the difference of acidity value and the change of acidity value with storage time were studied. The results showed that the acidity value of mature honey was 5 - 8 ml/kg;the acidity value of non-mature honey or water honey was higher than that of mature honey;and most of them were above 10 ml/kg;the acidity of ripe honey increased after 1 year, but most of them were still less than 10 ml/kg. The acidity of non-mature water honey increased;some of them were close to or even higher than 40 ml/kg, and the rancidity was obvious. According to the requirements of relevant industry standards in China, the acidity value of normal honey should be less than 40 ml/kg. We can know that the initial acidity value of mature honey and non-mature honey can be within a reasonable range. With the extension of time, the acidity of honey showed an increasing trend. The acidity of mature honey changed little, but the acidity of non-mature honey increased significantly, which showed that non-mature honey was not good to be preserved or even could not be preserved normally;after a certain period of storage, the acidity of honey will naturally increase beyond a reasonable range. So when the acidity of honey is high to a certain value, it is likely to be non-mature honey, water honey, or rancid honey.
