The aim of this study was to investigate the proteolytic ability of some strains of aspergilli, fusaria, and penicillia and the metabiotic effect of Fusarium oxysporum and Penicillium expansum on Salmonella. The proteolytic activity of the target molds was determined on tomato juice agar and tomato juice, whereas the metabiotic effect of F. oxysporum and P. expansum on Salmonella was assessed in a model system consisting of tryptone soy broth with different amounts of tomato juice added. Fusaria, some aspergilli, and one strain of penicillium showed a proteolytic activity on tomato juice agar. In addition, Salmonella survival was enhanced in tryptone soy broth plus 20 or 50% tomato juice in the model system previously inoculated with F. oxysporum.

Background: The loss of flavor in modern tomato cultivars represents a great challenge for the food industry. This study investigated the potential of power ultrasound as an innovative approach to improve tomato juice flavor by releasing bound volatiles.
Results: It was found that power ultrasound offered a more viable, environmentally friendly technique for enhancing the aroma of tomato juice compared with enzymatic or acid hydrolysis methods.

Diverse species of yeasts are commonly associated with food and food production environments. The contamination of food products by spoilage yeasts poses significant challenges, leading to quality degradation and food loss. Similarly, the introduction of undesirable strains during fermentation can cause considerable challenges with the quality and progress of the fermentation process.

Background/objectives: This study explores the significance of beetroot and tomato juices, two prominent health-promoting foods known for their rich nutrient content and bioactive compounds. The growing consumer awareness of the link between diet and well-being emphasizes the need for food producers to align their products with health-conscious preferences. The aim of this research was to assess the composition, color, and sensory attributes-specifically color, taste, and odor-of various commercially available beetroot and tomato juices and to evaluate their acceptability among consumers.
