Effects of Laminaria japonica on the physico-chemical and sensory characteristics of reduced-fat pork patties

Reduced-fat pork patties produced with the addition of Laminaria japonica powder were evaluated for the chemical composition, cooking characteristics and sensory properties. Reduced-fat pork patties containing L. japonica powder had significantly higher moisture, ash, carbohydrate content, yellowness, and springiness than the control sample (P < 0.05). Protein and fat contents, energy value, lightness, redness, cooking loss, reduction in diameter, reduction in thickness, hardness, gumminess, and chewiness of the regular-fat (20%) control samples were significantly higher than reduced-fat pork patties containing L. japonica (P < 0.05). The sensory evaluations indicated that the greatest overall acceptability in reduced-fat pork patties was attained at a L. japonica concentration of 1 or 3%. Pork patties with fat contents reduced from 20% to 10% and supplemented with 1 or 3% L. japonica had improved quality characteristics that were similar to the control patties containing a fat content of 20%.
