The industry demands high quality and standards-compliant beeswax, which is difficult to find in western countries. As a result, it is necessary to explore new geographical sources. This work focuses on the characterization of beeswax from Mozambique in terms of saturated hydrocarbon profile and thermal properties comparing them with others from diverse origins. The hydrocarbons found (C21H44-C35H72) do not contain enough information for its differentiation. However, melting and cooling enthalpies together with all the temperatures associated with the different lipid polymorphic forms achieved this goal. A higher average melting enthalpy values obtained in Mozambique samples (up to 234 J/g) and Honduras (231 J/g) indicates more energy is required to melt these beeswaxes than those from Spain (193 J/g) and an analytical reactive pure beeswaxes considered as “reference” (168 J/g). This might be linked to the tropical temperatures where the bees produce specific wax. These results are significant in characterizing beeswax from tropical climates and for the industry to exploit its peculiar properties.

莫桑比克和其他产地蜂蜡的热特性和碳氢化合物成分

该行业需要高质量且符合标准的蜂蜡,这在西方国家很难找到。因此,有必要探索新的地理来源。这项工作的重点是莫桑比克蜂蜡的饱和烃特征和热性质方面的表征,并将其与不同来源的其他蜂蜡进行比较。发现的碳氢化合物 (C 21 H 44 -C 35 H 72)不包含足够的信息来区分。然而,熔化和冷却焓以及与不同脂质多晶型相关的所有温度实现了这一目标。莫桑比克样品(高达 234 J/g)和洪都拉斯样品(231 J/g)获得的平均熔化热值较高,表明熔化这些蜂蜡比来自西班牙的样品(193 J/g)和分析反应纯需要更多的能量。蜂蜡被视为“参考”(168 J/g)。这可能与蜜蜂产生特定蜡的热带温度有关。这些结果对于表征热带气候的蜂蜡以及该行业开发其独特性能具有重要意义。
