•Pectin and insoluble fiber were separated from soy hull (SH) flours.•Beef patties were formulated with 1% pectin, insoluble fiber, or their mixture.•SH pectin decreased display weight loss and increased cook yield of beef patties.•SH pectin minimized hardness change of frozen/thawed beef patties.•Insoluble SH fiber decreased color and lipid oxidation stabilities of beef patties.
The objective of this study was to determine the effects of pectin and insoluble fiber isolated from soy hulls on water-holding capacity (WHC), texture, color, and lipid oxidation of fresh and frozen/thawed beef patties. Beef patties were formulated with no dietary fiber (control), 1% soy hull pectin, insoluble fiber, or their mixture (1:1), respectively. The addition of soy hull pectin significantly decreased display weight loss and increased cook yield of both fresh and frozen/thawed beef patties. In addition, no significant difference in hardness between fresh and frozen/thawed beef patties was observed for all dietary fiber treatments. However, incorporation of insoluble soy hull fiber decreased color and lipid oxidation stabilities of both fresh and frozen/thawed beef patties. Our results indicate that the incorporation of soy hull pectin could be an effective non-meat ingredient to minimize water loss and hardness defects of frozen beef patties.
