This study aimed to evaluate the chemical composition, antioxidant activity, and spectral profile of honey samples collected from different geographical origins within the Amazonas region (Peru). Color parameters, total phenolic content, and antioxidant activity were determined. Sugar composition (glucose, fructose, and sucrose) was quantified by UHPLC, while Fourier-transform infrared spectroscopy (FTIR), combined with chemometric analyses (PCA and HCA), was used to assess spectral variability and sample differentiation. The results revealed significant variability among samples ( p \u003C 0.05), which may be associated with differences in the production areas analyzed and the overall sample composition. Dark-colored honey samples showed higher phenolic content (634–643 μmol TE\u002F100 g), whereas light-colored honey samples showed lower bioactive potential (\u003C300 μmol TE\u002F100 g). Glucose and fructose were the predominant sugars, with concentrations ranging from 40.20 to 46.50 g\u002F100 g and 25.10 to 36.50 g\u002F100 g, respectively. Sucrose content varied among samples (3.16–12.60 g\u002F100 g), with some exceeding the reference limit of 5 g\u002F100 g. FTIR spectra confirmed the presence of characteristic functional groups related to carbohydrates, water, and minor compounds. Chemometric analysis enabled the discrimination of samples into distinct groups based on compositional differences, explaining up to 84.0% of the total variance in PCA. Positive correlations were found between total phenolic content and antioxidant activity ( r = 0.92–0.94, p \u003C 0.001), suggesting an association between phenolic content and antioxidant activity. This preliminary study provides insights into the chemical variability, antioxidant activity, sugar composition (fructose, glucose and sucrose), and FTIR spectral profiles of honey samples from the Amazonas region. However, future studies including a larger number of samples and complementary analyses will provide a more comprehensive understanding of the factors associated with honey variability.","蜂蜜是一种复杂的天然产物，其化学组成和生物活性特性可因地理来源和生产条件的不同而存在差异。本研究旨在评估采集自秘鲁亚马孙地区不同地理来源的蜂蜜样品的化学组成、抗氧化活性及光谱特征。测定了色泽参数、总酚含量和抗氧化活性。采用超高效液相色谱（UHPLC）对糖类组成（葡萄糖、果糖和蔗糖）进行定量分析，同时利用傅里叶变换红外光谱（FTIR）结合化学计量学分析（PCA和HCA）评估光谱变异性并实现样品区分。结果表明，样品间存在显著差异（p \u003C 0.05），这可能与分析的生产区域差异及样品整体组成不同有关。深色蜂蜜样品的酚类含量较高（634–643 μmol TE\u002F100 g），而浅色蜂蜜样品的生物活性潜力较低（\u003C300 μmol TE\u002F100 g）。葡萄糖和果糖为主要糖类，浓度范围分别为40.20–46.50 g\u002F100 g和25.10–36.50 g\u002F100 g。蔗糖含量因样品而异（3.16–12.60 g\u002F100 g），部分样品超过了5 g\u002F100 g的参考限值。FTIR光谱证实了与碳水化合物、水分及微量化合物相关的特征官能团的存在。化学计量学分析能够根据组成差异将样品区分为不同组别，在PCA中可解释高达84.0%的总方差。总酚含量与抗氧化活性之间呈正相关（r = 0.92–0.94，p \u003C 0.001），表明酚类含量与抗氧化活性之间存在关联。本初步研究为了解亚马孙地区蜂蜜样品的化学变异性、抗氧化活性、糖类组成（果糖、葡萄糖和蔗糖）及FTIR光谱特征提供了参考。然而，未来纳入更多样品及补充分析的研究将有助于更全面地理解与蜂蜜变异性相关的因素。",null,"Frontiers in Sustainable Food Systems","2026-09-10T00:00:00Z","论文",10,false,62,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},8,18,14,13,9,1,"秘鲁亚马孙蜂蜜的化学组成与FTIR光谱鉴别研究，方法有参考价值但属区域性初步研究，产业影响有限。",[25],{"name":10,"url":6},[27,28,29,30,31],"光谱检测","蜂产品","农产品品质","地理溯源","抗氧化活性",0,"10.3389\u002Ffsufs.2026.1929136",{"doi":33,"openalex_id":35,"authors":36,"venue":10,"cited_by_count":32,"oa_url":6,"card":54,"direction":58,"ingested_from":60},"W7212125106",[37,40,42,44,46,48,50,52],{"name":38,"orcid":39},"Katherine Reyna-Gonzales","https:\u002F\u002Forcid.org\u002F0000-0002-5579-8238",{"name":41,"orcid":9},"Juan Carlos Altamirano-Oporto",{"name":43,"orcid":9},"Alexa J.
