Compound-specific stable isotope analysis (CSIA) of food products is a relatively new and novel technique used to authenticate food and detect adulteration. This paper provides a review of recent on-line and off-line CSIA applications of plant and animal origin foods, essential oils and plant extracts. Different food discrimination techniques, applications, scope, and recent studies are discussed. CSIA δC values are widely used to verify geographical origin, organic production, and adulteration. The δN values of individual amino acids and nitrate fertilizers have proven effective to authenticate organic foods, while δH and δO values are useful to link food products with local precipitation for geographical origin verification. Most CSIA techniques focus on fatty acids, amino acids, monosaccharides, disaccharides, organic acids, and volatile compounds enabling more selective and detailed origin and authentication information than bulk isotope analyses.. In conclusion, CSIA has a stronger analytical advantage for the authentication of food compared to bulk stable isotope analysis, especially for honey, beverages, essential oils, and processed foods.
食品的化合物特异性稳定同位素分析（CSIA）是一种相对较新的技术，用于鉴定食品和检测掺假。本文综述了植物和动物源性食品、精油和植物提取物的在线和离线 CSIA 的最新应用。讨论了不同的食品鉴别技术、应用范围和最新研究。CSIA δC 值广泛用于验证地理来源、有机生产和掺假。单个氨基酸和硝酸盐肥料的 δN 值已被证明可用于鉴定有机食品，而 δH 和 δO 值可用于将食品与当地降水联系起来，以验证地理来源。大多数 CSIA 技术都集中在脂肪酸、氨基酸、单糖、二糖、有机酸和挥发性化合物上，与批量同位素分析相比，能够提供更具选择性和详细的来源和鉴定信息。总之，与批量稳定同位素分析相比，CSIA 在食品鉴定方面具有更强的分析优势，尤其是在蜂蜜、饮料、精油和加工食品方面。
