This study aimed to assess bioactive compounds contents in cherry tomatoes and classify samples according to cultivation techniques. Simple and cost-effective analyses were conducted on 128 samples cultivated using hydroponic, organic, and conventional practices. An HPLC-FD method was validated in-house for eight biogenic amines while antioxidants were evaluated using total phenolic content and anti-radical activity assays (DPPH and ABTS+ assays). Chemometric evaluation was applied to extrapolate significant information from data-sets. Variable selection using correlation matrix and the Fisher test was performed. Principal component analysis and linear discriminant analysis were used to construct a mathematical model to classify samples. Correct classifications were achieved in training (95.2%), validation (98.5%), and testing (100%). The results showed that cherry tomatoes cultivated using different techniques could be discriminated based on bioactive profiles using chemometric approaches.

Abstract

This study aimed to assess bioactive compounds contents in cherry tomatoes and classify samples according to cultivation techniques. Simple and cost-effective analyses were conducted on 128 samples cultivated using hydroponic, organic, and conventional practices. An HPLC-FD method was validated in-house for eight biogenic amines while antioxidants were evaluated using total phenolic content and anti-radical activity assays (DPPH and ABTS+ assays). Chemometric evaluation was applied to extrapolate significant information from data-sets. Variable selection using correlation matrix and the Fisher test was performed. Principal component analysis and linear discriminant analysis were used to construct a mathematical model to classify samples. Correct classifications were achieved in training (95.2%), validation (98.5%), and testing (100%). The results showed that cherry tomatoes cultivated using different techniques could be discriminated based on bioactive profiles using chemometric approaches.
