摘要: Chemical reactions occur during freezing and frozen storage of foods. Whereas some these may be desirable, more often than not they have undesirable consequences. Understanding is therefore critical in controlling minimizing the detrimental changes that subsequent storage. To monitor reactions, measurement chemical markers food product conducted. are compounds whose concentrations reflect quality. The usefulness illustrated by their ability to provide quantitative information, used predictive modeling, mimic other processes take place vicinity site where measurements made. objective this chapter discuss both preparation for analysis analytical methods quantify reactions. Proceeding from discussion traditional techniques, will also touch on development application new sensor technologies should a major impact quality evaluation
