Summary: The objective of this study was to investigate the effect of blood product enrichment on techno-functional and instrumentally measured sensory properties of meat batter products. Types and quantities of enrichment were determined according to the literature taking into account the usability. The factors of the research were the followings: type of blood product enrichment (blood plasma, hemoglobin and whole blood powder), quantity of blood product enrichment (control; 10 g·kg-1, 30 g·kg-1 and 50 g·kg-1 in case of hemoglobin and whole blood powder; 10 g·kg-1, 30 g·kg-1, 50 g·kg-1, 100 g·kg-1 and 150 g·kg-1 in case of blood plasma powder) and storage time (0 days, 30 days, 60 days and 90 days). Effects of the factors on the measured attributes were evaluated by general linear models by multivariate analysis of variance (MANOVA) and Tukey’s honestly significant difference (HSD) post-hoc test for statistical significance of p < 0.05. A clearly positive effect of blood products containing albumen was found on textural properties, which was observed by scanning electron microscopy. Besides, type as well as quantity of the blood product enrichment affected colour and techno-functional properties.
