Resumen:
In this work, chemical crosslinking with 1,4-butanediol diglycidyl ether(BDDGE) is used as strategy to enhance mechanical performance of fish gelatin (FG) gels in order to meet the properties´ range of mammalian gelatin physical gels. Joint analysis of free amino groups, swelling ratio, and total solublematerial indicates that crosslinking degree increases with increasing FG concentration and it is favored by a 0.2 BDDGE/FG ratio. Increasing crosslinkingdegree enhances gel indentation strength and shear modulus (μ) whiledecreases fracture toughness (GIC). Measured μ and GIC values lies within therange exhibited by mammalian gelatin physical gels, but the relationshipbetween these parameters is opposite. This is due to the different fracturemechanisms occurring in chemically crosslinked and physical gels.
