摘要
Abstract
In order to probe reason of texture deterioration and improve texture quality, moisture status change of ready-to-eat shrimps during storage were studied. Results of TPA indicated that texture of shrimps deteriorated obviously during storage. Moisture status change was analyzed by means of DSC and LF-NMR. Results showed that contents of bound and intermediate water decreased in the late of storage. It is thus clear that there was a transformation from intermediate and bound water to free water during the storage. Main reason is the destruction of protein-water system due to protein degradation. Protein degradation and moisture stasus change lead to quality deterioration of ready-to-eat shrimps during storage. It provides theoretical basis for improving storage quality of ready-to-eat shrimps.
