Value-Added Carp Roe Salad Supplemented with Orange Carrot Pomace Powder

Carrot pomace is the solid residue left after juice extraction from carrots. Carrot pomace, typically seen as waste, is gaining recognition for its sustainability and potential to mitigate food waste while offering essential nutrients (phenolics, carotenoids, and β-carotene), which are recognized for their nutraceutical effects and health benefits. A study was conducted to develop a process for creating an innovative product, specifically a carp roe salad with added value, by incorporating carrot pomace. The innovative aspect is represented by using different proportions of carrot powder, 6% and 12%, when creating new varieties of roe salad. The study assesses the impact of carrot pomace powder on the salad's antioxidant content, physicochemical properties, color, texture, rheological characteristics, and sensory qualities. The value-added products thus obtained are differentiated by superior phytochemical and nutritional characteristics, especially levels of carotenoids (84.01 ± 3.39-111.01 ± 1.68 mg/100 g DW), and the antioxidant activity (550.66 ± 9.25-588.32 ± 9.41 μM TE/g DW) of the developed salad. The obtained products displayed an improved color and texture profile. The sensory evaluation reveals that the carp roe salad with 12% carrot powder was favorably received by consumers, who valued the nuanced changes in flavor and the improved coloration of the product. Rich in antioxidants, fibers, and natural colorants, carrot pomace enhances the product's value by increasing antioxidant activity and positively influencing sensory properties such as color and aroma. This research highlights the potential of using food by-products to create innovative, value-added products with improved health benefits.
