Summary

Shrimp (Pandalus borealis) from a commercial freezer trawler were thawed then subjected to different treatments (conditioning) by holding them in ice, water and brine of various salt concentrations before being steam-cooked and peeled. Various parameters such as pH, peelability, yield, salt content, dry matter, and water holding capacity were measured. Near infrared (NIR) spectra were obtained on samples of whole shrimp and minced flesh from the various treatments. Analysis of the spectral and compositional, treatment and processing data using principal components and partial least squares indicated that NIR could be used to distinguish between frozen and thawed material, between salt content, pH in the flesh, cooking period (temperature) of both whole or minced shrimp. NIR data could not be used to determine peelability, water holding capacity, dry matter or salt content in whole or minced shrimp.
