Abstract

The quality characteristics of cookies between fresh shredded garlic(FSG) and heat-treated($150^{\circ}C$, 5 min) shredded garlic (HT-SG) were comparatively analyzed based on different content additions. The levels investigated were 0, 0.5, 1, 2, 4 and 6% for both shredded garlics. Dough pH was lower in the FSG-added cookies than in the HT-SG-added cookies. The spread factor decreased with the addition of shredded garlic compared to the control($10.63{\pm}0.57$), but differences were insignificant within each group. Cookies hardness was highest at 2% garlic content, and it was higher for HT-SG than FSG. Compared to the measured L-value of the control, the L-values of the test samples decreased with increasing garlic contents. With increasing garlic contents, the a-value increased, but the b-value remained mostly unchanged, with less significant difference compared to the control. The color of the HT-SG group tended to be brown as the garlic content increased. The degree of browning was more pronounced for HT-SG than FSG. Surface cracking of the cookies tended to be higher in the FSG samples than in HT-SG. Compared to the control, garlic taste and flavor increased remarkably with increasing garlic content, and they were stronger for the FSG cookies. The overall acceptability of HT-SG was relatively high, and it was highest for the HT-SG cookies with a 0.5~2% garlic contents than for the control cookies.
