    Blackcurrants are sources of phenolic compounds, such as anthocyanins, possessing strong antioxidant, anti- microbial and antifungal activity. Therefore, the addition of different blackcurrant pomace ingredients may affect the overall meat quality. The actual chemical profile and bioactivities of blackcurrant pomace ingredients may strongly depend on its preparation; for instance, in our study the highest values of the in vitro antioxidant capacity were determined for blackcurrant seeds after supercritical CO2 extraction. Starting from these back- ground conditions, in this work, we evaluated the ability of three different concentrations (namely 1, 3, and 5% w/w) of blackcurrant (BC) seeds following EtOH/water extraction (BC-AE), before supercritical fluid CO2 extraction (BC-RS), and after supercritical fluid CO2 extraction (BC-ASC) to affect different quality parameters of pork meatballs. These latter were stored considering three different time-points, namely 1, 3 and 6 days at 4 ◦C packed under modified atmosphere (i.e., 70% N2 and 30% CO2). Untargeted metabolomics allowed to identify several lipid and protein-related oxidation products involved in redox reactions, such as 13-L-hydroperoxylino- leic acid, (12S,13S)-epoxylinolenic acid, 9,10-epoxyoctadecenoic acid, glutathione, glutathione disulfide, L- carnosine, L-ascorbic acid, and tocotrienols. Besides, multivariate statistics applied on the metabolomics dataset confirmed that the chemical profile of meatballs was an exclusive combination of both BC inclusion levels and type of BC-ingredients considered. Our findings showed that the higher the concentration of BC seed ingredients in meatballs, the lower the cooking loss and the higher the fibre content. Also, all the ingredients significantly affected the colour parameters.

    Meat extenders from different sources as protein-rich alternatives to improve the technological properties and functional quality of meat products
    (Elsevier, 2023) Rocchetti, Gabriele; Ferronato, Giulia; Sarv, Viive; Kerner, Kristi; Venskutonis, Petras R; Lucini, Luigi
    In the last years, animal proteins from meat and meat-derived products have represented one of the main concerns to achieve a sustainable food production. Within this perspective, the partial replacement of meat with nonmeat substances having a high- protein content, offers interesting opportunities to reformulate more sustainable meat products characterized also by potential health-promoting properties. Therefore, starting from these background conditions, this short review critically summarizes recent findings on extenders from different origins, namely pulses, plant-based ingredients, plant by-products, and unconventional sources, as valuable possibility to improve the technological profile and functional quality of meat, together with providing a focus on their ability to affect the sustainability of meat products.

    Untargeted metabolomics and conventional quality characterization of rowanberry pomace ingredients in meatballs
    (Elsevier, 2023) Sarv, Viive; Kerner, Kristi; Venskutonis, Petras Rimantas; Rocchetti, Gabriele; Becchi, Pier Paolo; Lucini, Luigi; Tänavots, Alo; Bhat, Rajeev
    In this study, a rowanberry pomace defatted with supercritical CO2 (2%-AC), its ethanolic extract (1%-E) and extraction residue (2%-R), were tested in meatball preparation. The meatballs with 1%-E demonstrated the highest in vitro radical scavenging capacity. In the case of 1%-E the pH of meatballs was significantly lower compared to the control sample (P = 0.0132) on the 5-day. The lowest cooking loss was achieved when the meatballs contained mainly fibre-rich 2%-R. The UHPLC method detected 184 metabolites, including strong antioxidants, such as chlorogenic acids, 3′,4′-methylenedioxy-5,7-dimethylepicatechin, hyperin, isoquercitrin. The 1%-E was particularly effective against the development of unpleasant off-flavours caused by carbonyl compounds. Consistently, the decrease in lipid oxidation, indicated by reduced 7-dodecenal and 2,4-heptadienal contents, has been observed following the addition of rowanberry extract to meatballs. Metabolomics coupled with conventional quality evaluations provided a deeper understanding of the potential utilization and valor- isation of different rowanberry pomace extracts as meat ingredients.
