Abstract
New heat-induced gel products prepared from farmed meagre (Argyrosomus regius) and psyllium dietary fiber (DF; up to 4.0%, w/w) with reduced salt content (from 2.5 to 1.0%, w/w) were studied. The effect of chilled storage time (15 days vs. 1 day) was also measured. Psyllium DF worsened breaking force and deformation as well as springiness, but it did not affect the remaining textural properties and improved water holding capacity (WHC). Salt reduction from 2.5 to 1.0% (w/w) decreased breaking force and deformation, cohesiveness, and WHC. The textural, color, and WHC properties of heat-induced meagre gels were unaffected by chilled storage time. Results pointed to the feasibility of using psyllium DF addition up to 4.0% (w/w) as a strategy not only to improve nutritional value of the gel products, but also to countervail some of the negative effects of a lower salt content.
