. Sensory properties
The L. japonica powder concentration was found to affect the sensory
properties of reduced-fat pork patties, as shown in Table 6. The
mean values of the color, flavor, tenderness and juiciness were evaluated
to determine overall acceptability. The color score was the highest
for the control and increasing the L. japonica powder concentration
decreased the color score of reduced-fat pork patties (Pb0.05). This
result may show that reduced-fat pork patties were affected by adding
L. japonica powder, which the color of L. japonica was likely dark
brown. The flavor score of reduced-fat pork patties samples without
L. japonica powder (TC) was the lowest (Pb0.05) and there was no significant
difference in the flavor between the control and low-fat pork
patty samples containing L. japonica powder (P>0.05). Tenderness,
juiciness, and overall acceptability scores of reduced-fat pork patties
containing 1% and 3% L. japonica powder were significantly higher
than the control (Pb0.05), but reduced-fat pork patties not containing
L. japonica powder (TC) have the lowest (Pb0.05). Overall, the
reduced-fat pork patties produced with 1% and 3% L. japonica powder
had the highest scores, whereas the reduced-fat pork patties containing
10% fat without L. japonica powder had the lowest score. Similar
results were obtained by Kim et al. (2008), who examined the impacts
of seaweed on the quality characteristics of muffin, and by Cho and
Hong (2006), who studied the effects of adding seaweed to Korean
type bread. These results indicate that foods containing seaweed had
better sensory scores for overall acceptability when compared to the
control. Bloukas, Paneras, and Papadima (1997) reported that dietary
fibers had a beneficial influence on the sensory quality of reduced-fat
