Demand for honeydew honey (HDH) is growing, both from consumers and the food industry, due to its potential antimicrobial, anti-inflammatory, and antioxidant properties. However, information on the chemical profile of HDH remains scant, particularly on New Zealand honeydew honey (NZHDH). This paper aims to provide a comprehensive chemical analysis of NZHDH produced from honeybees, which feed on nectar exuded by the scale insect Ultracoelostoma assimile. This insect feeds on most species of the Southern Beech (Nothofagus spp.). The proximate composition, mineral profile, sugar profile, phenolic profile, amino acid profile, and antioxidant activity of NZHDH was determined and compared to results for HDH and other varieties of honey previously reported in literature. It was determined that the antioxidant activity of NZHDH is comparable to several studies on Manuka honey, which is widely considered as the "gold standard" for its antioxidant activity. This demonstrated that NZHDH indeed had excellent antioxidant properties. This study was the first time that a quantitative amino acid profile has been produced for NZHDH. The major amino acids were proline, L-aspartic acid, L-glutamic acid, L-alaine, and L-phenylalanine. The major phenolic compounds were pinocembrin, abscisic acid, and pinobanksin. Of the phenolic compounds quantified in this study, only p-hydroxybenzoic acid has previously been quantified in NZHDH.
由于其潜在的抗菌、抗炎和抗氧化特性，瓜纳花蜜（HDH）的需求正在增长，无论是来自消费者还是食品行业。然而，关于 HDH 的化学成分信息仍然很少，特别是关于新西兰瓜纳花蜜（NZHDH）的信息。本文旨在对由蜜蜂生产的 NZHDH 进行全面的化学分析，这些蜜蜂以蚧壳虫 Ultracoelostoma assimile 分泌的花蜜为食。这种昆虫以大多数南方山毛榉（Nothofagus spp.）为食。对 NZHDH 的近似成分、矿物质含量、糖含量、酚类含量、氨基酸含量和抗氧化活性进行了测定，并与文献中先前报道的 HDH 和其他蜂蜜品种的结果进行了比较。结果表明，NZHDH 的抗氧化活性可与几项麦卢卡蜂蜜的研究相媲美，麦卢卡蜂蜜因其抗氧化活性而被广泛认为是“黄金标准”。这表明 NZHDH 确实具有优异的抗氧化性能。本研究首次为 NZHDH 生成了定量的氨基酸图谱。主要的氨基酸是脯氨酸、L-天冬氨酸、L-谷氨酸、L-丙氨酸和 L-苯丙氨酸。主要的酚类化合物是 pinocembin、脱落酸和 pinobanksin。在本研究中定量的酚类化合物中，只有对羟基苯甲酸以前在 NZHDH 中被定量过。
