High moisture content (>20%) in stingless bee (kelulut) honey contributes to many undesirable reactions that deteriorate the quality of the honey. This study proposed an alternative method to facilitate moisture reduction in Geniotrigona thoracica honey using unglazed clay pots with different surface diffusion areas. Stingless bee honey with an initial moisture content of 26.4 ± 0.3 g/100 g was placed in two custom-designed clay pots, and a glass bottle (control), stored at 25 ± 2 °C and evaluated for 10 days. Results showed that the honey stored in the clay pot with the larger surface area reduced moisture content more effectively, i.e., <20% in <3 days. The pH and free acidity did not change over the storage period, indicating that the honey was stable against fermentation. Hydroxymethylfurfural was not detected in all samples, showing that the quality of honey was preserved. Molds and yeasts were not detected in honey stored in clay pots as the aw was relatively low (<0.63).

上无刺蜂的物理化学和微生物学性质陶罐的表面积(的效果Geniotrigona胸)蜜

无刺蜂(kelulut)蜂蜜中的高水分含量(> 20%)导致许多不良反应,从而降低了蜂蜜的质量。这项研究提出了另一种方法来促进胸腺Geniotrigona的水分减少蜂蜜使用表面扩散面积不同的无釉陶罐。将初始水分含量为26.4±0.3 g / 100 g的无刺蜂蜂蜜放入两个定制的陶罐和一个玻璃瓶(对照)中,在25±2°C下储存并评估10天。结果表明,储存在比表面积较大的煲中的蜂蜜可以更有效地降低水分含量,即在不到3天的时间内降低20%。在储存期间,pH和游离酸度没有变化,表明蜂蜜对发酵稳定。在所有样品中均未检测到羟甲基糠醛,这表明蜂蜜的品质得以保留。在存储在陶罐作为一个蜂蜜中未检测到霉菌和酵母瓦特相对较低(<0.63)。
