Shrimp Processing Assessed by Low Field Nuclear Magnetic Resonance, Near Infrared Spectroscopy, and Physicochemical Measurements—The Effect of Polyphosphate Content and Length of Prebrining on Shrimp Muscle
Abstract: The effect of using polyphosphates during prebrining and the effect of prebrining time of cold water shrimp ( Pandalus borealis ) was studied with low field nuclear magnetic resonance (LF‐NMR) transverse relaxation time measurements (benchtop and unilateral) and near infrared (NIR) spectro...
