Tóm tắt

Mango (Mangifera indica L.) is a tropical fruit of the Anacardiaceae family, origin in the Indo–Burma – Malay region and later spread to other regions. Vietnam is a major global mango producer; however, the expansion of international trade has increased the prevalence of low-quality and fraudulent products, emphasizing the necessity of origin identification for quality assurance and market integrity. This study investigated the traceability of Vietnamese mangoes, especially the valuable Hoa Loc mango variety, through an integrated analytical approach using principal component analysis (PCA) on inductively coupled plasma mass spectrometry (ICP-MS) elemental concentrations. Mango samples from Tien Giang, Vinh Long, Dong Thap, and Can Tho provinces were evaluated for their elemental composition(Mg, Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Sr, Mo, Ag, Cd, Sb, Cs, Ba, Hg, and Pb). PCA of the elemental data showed significant differences between regions. Important elements for distinguishing mango samples included Mg, Cu, Rb, Sr, Cs. Notably, Can Tho samples had the highest Mg concentration (140.83 µg/g), while Tien Giang had the lowest concentration (28.30 µg/g). Cu concentration in Tien Giang also the lowest of the 4 provinces (0,21±0,02 µg/g) and Can Tho is the highest (1,96±0,04µg/g). The above differences contributed to the assessment of the origin of mango samples. Other notable elements such as Al, Ti Cr, Fe were also analyzed and evaluated by province. The results of this study demonstrate the effectiveness of applying advanced analytical techniques in traceability and quality control of Hoa Loc mangoes in particular, and agricultural products in general.
