Effect of the addition of unconventional flours and low salt content on restructured bonefish (Albula vulpes) products

| Shrnutí: | Restructured seafood products are primarily processed from undervalued fish species, fillet trimmings, or by products of non-commercial fish species. One of the underrated fisheries in southern Mexico is that of the bonefish (Albula vulpes). The objective of this study was to evaluate the effect of adding non-conventional flours and reducing the sodium chloride level on the mechanical and functional properties of restructured bonefish products. Bonefish restructured products were prepared to analyze samples with (0 %, 5 %, and 10 %) amaranth flour (AF) or cricket flour (CF) and three levels of salt (0 %, 1 % and 2 %). The cooking water loss, the amount of extractable water and the texture from gels were evaluated. The use of both non-conventional flours reduced cooking water loss by 49.09 % to 61.97 % with 1 % salt. The addition of salt reduced the extractable water in the restructured product. Hardness values varied (P < 0.05) among treatments. The highest hardness was obtained in treatments with 10 % AF and 1 % salt (64.55 N) and with 10 % CF and 2 % salt (63.50 N). Cohesiveness ranged from 0.53 to 0.71 (dimensionless) in treatments with 1 % and 2 % salt, indicating minimal changes in internal structure due to additives. Non-conventional flours allowed for protein gelation, forming restructured products with suitable textural properties for a meat product. The addition of 10 % CF or AF and 1 % salt in fish restructured product formulation offers a healthy alternative in the development of fish-based foods. |
