Abstract(s)

Introduction: Fungal spoilage is a key concern for the food industry, leading to hefty economic losses Consequently, the food waste that follows is also a grave matter not only due to its social or humanitarian aspect but also its environmental impact. Objectives: The aim of this study was to assess the antifungal activity of commercial clean label alternatives to potassium sorbate against moulds isolated from a pastry filling. Methodology: Isolation of fungi from a contaminated product used in antimicrobial activity tests of clean label preservatives. Results and discussion: Fungal growth was not completely inhibited at the concentrations recommended by the manufacturers. The antimicrobial agents are still effective and, therefore, a promising alternative to traditional chemical preservatives for the pastry industry. Conclusions: In this context, the clean label movement is trending to offer natural spoilage control strategies while having their organoleptic characteristics and, most importantly, safety in sight. Future research into the application of these antimicrobial compounds in pastry fillings is an important step to guarantee their efficacy and application in the industry.
