Effects of ultrasound, CaCl2 and STPP on the ultrastructure of the milk goat longissimus muscle fiber observed with atomic force microscopy

Summary The aim of this study was to analyze the effects of ultrasound bath intensity, CaCl2 and sodium tripolyphosphate (STPP) concentration on the ultrastructure of longissimus muscle fiber from milk goats. The sarcomere length was measured by atomic force microscopy. According to the results of AFM images, the sarcomere length is longest when the conditions were an intensity of 100 W ultrasound bath (42.77% increment), a concentration of 300 mM CaCl2 injection (44.68% increment) or 90 mM STPP injection (19.41% increment). Apart from the sarcomere length, the study put forward a potential index (roughness) to represent tenderness of meat which was treated by ultrasound bath. Among different methods, ultrasound bath was chosen as the preferred tenderization method. SCANNING 9999:1–9, 2016. © 2016 Wiley Periodicals, Inc.
