Physicochemical characteristics of surimi-like material made from the muscle tissues of freshwater mussels (Sinanodonta woodiana Lea, 1834)

Abstract The aim of the study was to determine selected characteristics surimi-like material (SLM) made from muscle tissues Sinanodonta woodiana (Lea, 1834) freshwater mussels. research consisted unwashed mussel homogenate as control sample—C, tissue twice washed with water (SLM-W) and sample NaCl at a concentration 0.169 mol/L well (SLM–S). A raw surimi like-materials were analysed using SDS-PAGE technique. They also tested DMTA method (dynamic mechanical thermal analysis) while heating samples up 80 °C cooling 20 °C. drip texture gels after (75 °C, 30 min) determined. washing procedure had significant impact on protein composition SLMs. significantly (p < 0.05) higher percentage proteins molecular weights 270–273 kDa 105–110 (corresponding specific filamin isoforms), 42–43 actin), found in SLMs compared C. Ccorrelation analysis confirmed strong positive relationship between share above values elasticity modulus (r ≥ 0.84) firmness 0.88) SLM gels. SLM-S characterised by lowest values. During heating, rheological traits all changed two stages: 50 over highest dynamics variation (G′) value noticed temperatures exceeding samples. G′ greater than revealed correlation 0.81) determinants their parameters. Sample SLM-W one showed that textural properties mainly resulted reaction spatial matrices interactions.
