Thermal Ionisation Mass Spectrometry (TIMS) was applied to discriminate a total of 118 tomato samples (berries, "passata", tinned tomatoes, sauce, double and triple concentrate) coming from two different countries. The TIMS technique gave significantly different results for the (87)Sr/(86)Sr ratios and δ‰ values between Chinese and Italian tomato samples, irrespective of the treatment type. This technique proved to be a "robust" method, suitable for a precise discrimination of the two geographical origins. TIMS was able, within the Italian samples, to discriminate different geographical production areas, by virtue of different (87)Sr/(86)Sr ratios and δ‰ values. This technique could be employed in the field of food safety and quality, as a profitable tool for authenticating tomato geographical origin.
热电离质谱法（TIMS）被应用于区分来自两个不同国家的总共 118 个番茄样本（浆果、“番茄酱”、罐装番茄、酱汁、双份和三倍浓缩物）。TIMS 技术在（87）Sr/（86）Sr 比值和 δ‰ 值方面给出了中国和意大利番茄样本之间的显著不同结果，无论处理类型如何。该技术被证明是一种“稳健”的方法，适用于对两个地理来源的精确区分。TIMS 能够在意大利样本中，通过不同的（87）Sr/（86）Sr 比值和 δ‰ 值来区分不同的地理生产区域。该技术可用于食品安全和质量领域，作为验证番茄地理来源的有利工具。
