The possibility of modulation of patulin production by polyphenols from traditional Croatian traditional apple varieties within the project HRZZ-UIP-2020-02-8461

The effects of climate change, which play an important role in shaping environmental factors and intensifying the secondary metabolism of agriculturally important/foodborne fungal species, have led to an unexpected risk of contamination of food and feed with mycotoxins, which have enormous and complex implications for food safety and, consequently, for human health and the global economy. Several fundamental issues are at stake, but HRZZ-UIP-2020-02-8461 is attempting to come at least one step closer to solving the overall problem of avoiding modulation of fungicide efficacy due to changing climatic factors and stress the adaptation mechanisms of fungal cells, primarily for Penicillum expansum growth and the consequential patulin production. Apples are among the most popular fruits, but they are the most frequently infested by P. expansum and contaminated with its secondary metabolites. Despite this, there are currently no satisfactory strategies to reduce patulin concentrations in apples and apple products. However, there are traditional apple varieties that contain a higher number of polyphenolic compounds compared to commercial apple varieties. These compounds are an active component of plant defence against stress conditions. In addition, traditional varieties have higher antioxidant activity and a gene profile that makes them more resistant to climatic conditions, plant diseases, and other forms of abiotic stress. This has led to the idea of developing polyphenol-based strategies to reduce patulin content in apples and apple products, both for the ongoing HRZZ-UIP-2020-02-8461 and future projects. This presentation will provide an opportunity to discuss our idea, present initial published results, and identify potential new ways to achieve the overall goal of diminishing negative impact of mycotoxins from a food and feed safety perspective.
