The authors’ previous study16
certified that the released free purine-related compounds
in grass shrimp during cooking were
indeed transferred to the cooking juice. In the steps
after grinding and after cooking, the content of
Hyp decreased slightly, presumably because of the
amount of Hyp released and the surimi product
being filled in a sealed polyvinylidene chloride
case during cooking. Ade also decreased after
washing from 5.66 to 3.60 mmole/g dry basis, then
decreased steadily after grinding and cooking.
There were no differences in Gua during processing.
