TI  - Investigating the origin of tomatoes and triple concentrated tomato pastes 
      through multielement determination by inductively coupled plasma mass 
      spectrometry and statistical analysis.

AB  - The concentration of 32 elements (Al, As, Ba, Be, Ca, Cd, Ce, Cu, Dy, Fe, K, La, 
      Lu, Mg, Mn, Na, Nd, Pb, Rb, Sm, Sr, Th, U, V, Zn) was determined in tomatoes 
      harvested in different four Italian regions and in triple concentrated tomato 
      paste samples coming from Italy, China, Greece and California. The resulting 
      multielement profiles were processed using three chemometric techniques to 
      evaluate the possibility of discrimination between different cultivation areas. 
      The closed-vessel microwave digested samples were diluted and analyzed by 
      DRC-ICP-MS with CH(4) as reaction gas. The accuracy of the proposed method was 
      considered acceptable (values in the range 75-120%) for 25 out of the 35 elements 
      of the reference material NCS ZC85006 Tomato. The origin of tomato fruits and the 
      areas of production as "Italy" and "non-Italy" of the triple concentrated pastes 
      were evaluated by three supervised pattern recognition procedures, linear 
      discriminant analysis (LDA), soft independent modeling of class analogy (SIMCA) 
      and K-nearest neighbors (KNN).
