Real-time ultrasound (RTU) imaging methods for quality control of meats

In this chapter the use of real-time ultrasonography to predict in vivo carcass composition and meat traits will be reviewed. The chapter begins by discussing background and principles of ultrasound. Then aspects affecting the suitability of realtime ultrasonography and image analysis for predicting carcass composition and meat traits of meat producing species and fish will be presented. This chapter also provides an overview of the present and future trends in the application of real-time ultrasonography in the meat industry. © 2012 Woodhead Publishing Limited All rights reserved.info:eu-repo/semantics/publishedVersio

An investigation of rancidity inhibition during frozen storage of Wels catfish ( Silurus glanis

7 páginas, 3 figuras, 3 tablasThe effect of preliminary ascorbic and citric acid (AA and CA, respectively) soaking treatments on the rancidity development in Wels catfish (Silurus glanis) fillets during further frozen storage (−18 °C; up to 6 months) was studied. Rancidity development was measured by biochemical quality indices (formation of free fatty acids, peroxides and secondary oxidation products) and compared with sensory analysis (appearance, rancid odour and consistency) and general chemical analyses (pH, expressible moisture and heme iron contents). When compared with control samples, AA- and CA-treated samples showed a lower (P < 0.05) formation of primary and secondary lipid oxidation compounds that was corroborated by a longer (P < 0.05) shelf-life time as a result of a lower rancid odour formation. According to these results, control samples showed a higher (P < 0.05) heme iron breakdown (months 3–6) and a lower (P < 0.05) water-holding capacity (higher expressible moisture value) (month 6)Peer reviewe
