To our knowledge, micrographs of fish minced gels containing these several hydrocolloids (anionic and nonionic) prepared with specific optical techniques have not been published before. In order to determine how a variety of the seven hydrocolloids were distributed about the matrix
and how they interacted in this gelled protein matrix, two staining procedures were used (one for the non-ionic polysaccharides and another for the anionic polysaccharides). The characteristics of the different gels occurring with each hydrocolloid were also analysed.
