| Abstract: | The water activity ( a w) of canned mackerel, tuna and sardine was determined using three methods: a gravimetric and two instrumental methods. The a w values obtained by the gravimetric method, which only requires simple laboratory apparatus, were not significantly different from the values obtained by the other two methods, and can be used to determine high a w values. |
