The purpose of this study was to investigate the effects of the addition of various concentrations of antler powder on the physicochemical and sensory characteristics of mango jelly As for pH and viscosity of the mango jelly, antler powder added group showed higher pH and viscosity than that of control group. As for turbidity, absorbance increased significantly(p<.001) by the addition of antler while permeability decreased. The syneresis increased with the passage of time. According to sensory evaluation, Sleekness showed the highest by adding $0.2\%$ antler powder in mango jelly. The hunter color L and b value decreased significantly(p<.001) by adding antler powder. The mechanical properties such as hardness, springiness, cohesiveness and brittleness were highest by adding $1.0\%$ antler powder while gumminess was highest by adding $0.2\%$ antler powder in mango jelly. Overall quality, taste, appearance, texture were most superior by adding $0.2\%$ antler powder in mango jelly. From these test results, the optimum recipe for mango jelly added with antler powder was $0.2\%$ of antler powder, $10\%$ sugar, $\2%$ agar and 351.2ml of mango juice.

Hovenia dulcis fruit powder (HFP) has shown diverse functional activities; thus, it is rational to incorporate HFP into suitable food products with enhanced nutritional and functional quality, and their incorporation into bakery products such as cookies could be a good alternative for the increase of consumption. The aim of this study was to examine the effect of HFP addition on the quality characteristics of cookies. The pH of cookie doughs ranged from 5.80-6.34, with no remarkable differences by HFP addition. Density of cookie doughs significantly decreased upon addition of HFP (p<0.05), but there were no significant differences among samples added with HFP (p>0.05). Moisture content and spread factor of cookies significantly increased with higher content of HFP in the formulation (p<0.05). For color values of cookie surface, $L^*$ and $b^*-values$ decreased while $a^*-value$ increased as a result of HFP substitution (p<0.05). 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging activities were significantly increased (p<0.05) with higher substitution of HFP, showing a positive correlation. Hedonic sensory results indicated that cookies supplemented with 4% HFP received the most favorable acceptance scores for sensory attributes. Overall, HFP-added cookies could be developed with improved physicochemical qualities without sacrificing consumer acceptability.

This study aimed to determine the physicochemical properties (proximate composition, color, pH, salinity, water holding capacity (WHC), curing yield, and shear force) and sensory properties (electric nose and sensory evaluation) of Bulgogi sauce with added crust derived from dry-aged beef loin. Increasing the amount of crust in the Bulgogi sauce tended to increase the protein content, fat content, and pH. Uncooked Bulgogi also tended to have elevated fat content, ash content, pH, and shear force. Increasing the crust content tended to decrease the water content, lightness, redness, and yellowness of Bulgogi sauce. The yellowness of uncooked Bulgogi with 6%-12% crust in sauce was significantly lower than that of the control (no crust) and the sample with 3% crust in sauce (p<0.05). The redness of the cooked control Bulgogi was significantly lower than that of the samples with crust in sauce (p<0.05). The WHC of uncooked Bulgogi with 6%-12% crust in sauce was significantly higher than that of the control and the sample with 3% crust in sauce (p<0.05). The flavor, texture, and overall acceptability of the Bulgogi with 9% crust in sauce were significantly higher than those of the control (p<0.05). These findings showed that the crust did not degrade the physicochemical properties of Bulgogi sauce and meat. The sensory characteristics of Bulgogi marinated with 9% crust in sauce were rated the best as persensory evaluation. Therefore, crust is a suitable flavor enhancer for Bulgogi sauce, and a 9% addition amount is optimal in terms of quality.

Meat jerky is a type of meat snack with a long shelf life, light weight, and unique sensory properties. However, meat jerky requires a long manufacturing time, resulting in high energy consumption. In this study, beef jerky was prepared by injecting different concentrations of brine at different hot-air drying times (0-800 min). When the brine injection levels were increased to 30%, the drying characteristics of beef jerky, such as drying time and effective moisture diffusivity, were significantly improved owing to the relatively high water content and the formation of porous structures. The physicochemical properties (e.g. meat color, porosity, shear force, and volatile basic nitrogen) of the beef jerky injected with 30% brine were improved owing to the shortened drying time. Scanning electron microscopy images showed that the beef jerky structure became porous and irregular during the brine injection process. Our novel processing technique for manufacturing beef jerky leads to improved quality characteristics and shortened drying times.

The effects of low viscosity chitosan on the rheological properties of soymilk using a model system and on tofu qualities were examined. The flow behavior of soy milk with chitosan closed the Newtonian flow and stabilized according to increasing chitosan concentration. The soymilk containing $glucono-\delta-lactone$ exhibited a more pseudoplastic flow behavior compared with that of the control soymilk. The addition of low viscosity chitosan to the tofu preparation did not significantly affect its physicochemical properties. However, the results of the TEM image and instrumental textural properties showed that low viscosity chitosan affected the construction of the tofu structure. Chitosan tofu had low scores across the whole field of appearance in the sensory evaluation, and its overall eating quality was scored significantly lower. These results suggest that the addition of low viscosity chit os an affects the quality of tofu, which changes according to the degree of polymerization and concentration of chitosan.
