Abstract

(FJ), commonly known as Japanese knotweed, is now recognized as one of the most invasive plants in Europe and globally. Despite its widespread presence in Europe and its significant nectar production, there is currently limited scientific data on the unique unifloral honey derived from it. This study examines the physicochemical composition of honey (FJH) samples collected from various regions in Romania. Additionally, the nutritional and antioxidant profiles of FJH were assessed. The sensory analysis revealed a honey with a brown-caramel color and an intense flavor, characterized by fine, consistent crystals during crystallization. The results indicated that FJH has a high carbohydrate content (fructose: 35.12-40.65 g/100 g; glucose: 28.06-37.79 g/100 g); elevated electrical conductivity (387-692 µS/cm), diastase activity (9.11-17.01 DN), and acidity (21.61-42.89 meq/kg); and substantial total phenolic (89.87-120.08 mg/100 g) and flavonoid (18.13-39.38 mg/g) contents. These findings highlight FJH's favorable nutritional properties, aligning with the standard codex for honey. The antioxidant profile of FJH demonstrated strong DPPH and ferric reduction antioxidant power (FRAP) activities, comparable to those of buckwheat honey, underscoring its potential health benefits and commercial value. These results provide new insights into how this invasive plant can be harnessed as a valuable resource for sustainable beekeeping practices.

摘要

虎杖(FJ),俗称日本虎杖,现已被公认为欧洲乃至全球最具入侵性的植物之一。尽管它在欧洲广泛分布且花蜜产量可观,但目前关于源自虎杖的独特单花蜂蜜的科学数据有限。本研究检测了从罗马尼亚不同地区采集的虎杖蜂蜜(FJH)样本的理化成分。此外,还评估了FJH的营养和抗氧化特性。感官分析显示,该蜂蜜呈棕焦糖色,风味浓郁,结晶时晶体细腻均匀。结果表明,FJH碳水化合物含量高(果糖:35.12 - 40.65克/100克;葡萄糖:28.06 - 37.79克/100克);电导率(387 - 692微西门子/厘米)、淀粉酶活性(9.11 - 17.01 DN)和酸度(21.61 - 42.89毫克当量/千克)较高;总酚含量(89.87 - 120.08毫克/100克)和黄酮类化合物含量(18.13 - 39.38毫克/克)丰富。这些发现凸显了FJH良好的营养特性,符合蜂蜜的标准法典。FJH的抗氧化特性表现出较强的DPPH和铁还原抗氧化能力(FRAP)活性,与荞麦蜂蜜相当,强调了其潜在的健康益处和商业价值。这些结果为如何将这种入侵植物作为可持续养蜂实践的宝贵资源提供了新的见解。
