摘要: The present work examined water bath (WB) heating with microwave heating (WM) under different levels of transglutaminase (TGase) additions in a low-salt Mandarin fish surimi to obtain excellent gel properties. The breaking force was gradually enhanced with increased TGase additions (0.0- 0.8 U/g), while WM with 0.8 U/g TGase produced the maximum gel strength. In the texture analysis, WM depicted a reduced hardness and an increased springiness at the corresponding TGase additions than that of WB. In low-field nuclear magnetic resonance spectroscopy (LF-NMR) studies, TGase reduced water protons' relaxation times to different extents, while WM increased their water-binding abilities, especially at 0.8 U/g. Fourier transform infrared spectroscopy (FT-IR) revealed that the relative contents of the secondary structures did not apparently change at 0.2- 1.0 U/g. Therefore, using WM and adding 0.8 U/g TGase improved the gel quality of low-salt Mandarin fish surimi gel, providing a new strategy for preparing healthy surimi products.
