| Summary: | Consumer requirements for confectionery products have changed significantly over the past decade. These changes are evident in the growing demand for products that are high in protein but lower in energy content and, as a result, the market for these types of products is expanding. This study compared the chemical composition and functional properties of pork meat protein (MP) and blood plasma protein (BP) and evaluated their incorporation into cocoa cream formulations. Functional properties, such as water-holding capacity (WHC) and oil-holding capacity (OHC), were determined. Essential amino acid profiles were determined using HPLC analysis, and protein digestibility was evaluated both in the native form and after incorporation into the cocoa cream matrix via in vitro enzymatic digestion assays. Additionally, antioxidant activity of the enriched cocoa creams was assessed using the established ABTS assay. Results showed that BP contained a higher proportion of essential amino acids (26.44% of total amino acids), meeting the FAO/WHO recommendations, and exhibited superior digestibility compared to MP. Both proteins demonstrated high WHC and OHC values. The antioxidant potential of BP-enriched cocoa cream further supported its functional benefits. These findings indicate that blood plasma protein is a promising ingredient for enhancing the nutritional and functional quality of cocoa cream products. |
