This study reports on the physicochemical and sensory attributes, total phenolic content, and antioxidant activity of 36 honey samples produced by two different stingless bee species ( and ) from Australia. The findings reveal moisture content across all samples ranges from 24.9% to 30.8% (/), electrical conductivity from 1.02 to 2.15 mS/cm, pH levels between 3.57 and 6.54, soluble solids from 69.2 to 75.1 °Brix, trehalulose concentrations from 6.20 to 38.2 g/100 g, fructose levels from 7.79 to 33.4 g/100 g, and glucose content from 3.36 to 26.8 g/100 g. Sucrose was undetectable in all investigated samples. In a sensory analysis involving 30 participants, Australian stingless bee honey was perceived as having a more pronounced sourness compared with New Zealand Manuka honey. The study reveals considerable variability in the composition of Australian stingless bee honey, influenced by factors such as floral availability, geographical origin, and time of harvest. It also demonstrates the presence of phenolic compounds and antioxidant activity in stingless bee honey, underlining their potential as a natural source of antioxidants. All investigated samples contain trehalulose, which supports the findings of other recent studies that propose this unusual disaccharide as a marker compound of stingless bee honey.
本研究报告了澳大利亚两种不同无刺蜂(和)所产36份蜂蜜样品的理化和感官特性、总酚含量及抗氧化活性。研究结果显示,所有样品的水分含量在24.9%至30.8%(/)之间,电导率在1.02至2.15毫西门子/厘米之间,pH值在3.57至6.54之间,可溶性固形物在69.2至75.1°Brix之间,海藻酮浓度在6.20至38.2克/100克之间,果糖含量在7.79至33.4克/100克之间,葡萄糖含量在3.36至26.8克/100克之间。在所有调查样品中均未检测到蔗糖。在一项涉及30名参与者的感官分析中,与新西兰麦卢卡蜂蜜相比,澳大利亚无刺蜂蜂蜜被认为酸味更明显。该研究表明,受花源可用性、地理来源和收获时间等因素影响,澳大利亚无刺蜂蜂蜜的成分存在相当大的变异性。研究还证明了无刺蜂蜂蜜中存在酚类化合物和抗氧化活性,突显了其作为天然抗氧化剂来源的潜力。所有调查样品均含有海藻酮,这支持了其他近期研究的结果,即提出这种不寻常的二糖作为无刺蜂蜂蜜的标志性化合物。
