The chemical compositions of the raw material and Suan yu
differed significantly (P < 0.05) in the moisture, proteins, fat, salt
and ash contents (Table 2). High protein contents and low moisture
were found in all the fermented fish, suggesting that Suan yu could
be consumed as a nutritional and safe product. Chemical compositions
might be affected by the sources of raw materials, ingredients,
and the removal extents of water prior to processing as
well as the water loss during fermentation
