The Relationship Between Ergosterol and Alternaria Mycotoxins in Tomatoes With Different Surface Decayed Proportions

Abstract

This study evaluates the relationship between ergosterol (ERG) and Alternaria mycotoxins (AOH, AME, TenA) concentrations in tomato samples with varying decay levels. Using Rio Grande tomatoes, decay levels ranged from 89% to 99%. Samples were categorized based on visible mold, processed into pulp, and evaluated for quality parameters such as soluble solids, pH, acidity, and color. HPLC determined ERG, TenA, AOH, and AME levels, providing data on standard curve linearity, detection limit, recovery, and precision. Correlations between decay proportions and toxin concentrations were analyzed to understand variable relationships and quality implications for the tomato industry. Results indicate significant (p<0.05) effects of decay levels on toxin concentrations, emphasizing the importance of these measures for tomato quality assessment. The strong correlations among parameters underscore their relevance for quality control in tomato processing. This study contributes valuable insights for future research in this domain.
