    Abstract:
    On the basis of two experiments on the storage of raw shrimps (Pandalus borealis) in ice and on samples taken out from different trawlers after different days at sea, we have attempted to find the criteria of choice for the lower limit of quality of raw shrimps which are meant for further processing for human consumption. A content of TVN of approximately 50 mg/100 g peeled shrimp and a content of TMA-N of approximately 10 mg/100 g peeled shrimp probably represent such an objective lower limit if a comparison with organoleptic assessment is made. Assuming suitable storage conditions, this corresponds to a maximum period of 7 days. In this paper we have also attempted to find the content of TMAO in fresh raw shrimps from different fishing grounds in the Barents sea and off the Eastern coast of Greenland. The content of TMA-N was found to vary from 166 to 211 mg/100 g peeled shrimp.
