咖啡作为世界上人们最喜爱的饮品之一, 具有广阔的消费市场, 需求量巨大。但由于干旱和农作物疾病的影响, 近年来巴西、非洲等咖啡主要产地的咖啡产量显著下降。咖啡豆的资源紧缺和高利润导致咖啡真实性问题逐渐成为全球关注的热点。咖啡中的物种掺假、品种掺假和地理来源标示虚假是3种比较常见的真实性问题。本文综述了国内外研究者关于咖啡真实性鉴别技术的研究进展, 包括光谱检测技术、色谱/质谱检测技术、分子生物学检测技术和多种手段联合技术, 探讨了不同检测技术的优缺点, 并对该领域分析技术未来的发展趋势进行展望, 以期能为咖啡的真实性问题的解决提供资料参考和依据。 |
Coffee, as one of the world’s favourite beverages, has a broad consumer market and huge demand. However, due to drought and crop diseases, coffee production in Brazil, Africa and other major coffee-producing regions has declined significantly in recent years. The scarcity of resources and high profits of coffee beans have led to the issue of coffee authenticity gradually becoming a hotspot of global concern. Species adulteration, varietal adulteration and false geographical origin labelling in coffee are 3 kinds of relatively common authenticity problems. This paper reviewed the research progress of domestic and foreign researchers on coffee authenticity identification techniques, including spectroscopic detection techniques, chromatography/mass spectrometry detection techniques, molecular biology detection techniques and multi-means combined techniques, discussed the advantages and disadvantages of different detection techniques, and looked forward to the future development trend of analytical techniques in this field, with a view to providing information reference and basis for solving the authenticity problem of coffee. |
