The purpose of this study was to investigate the quality characteristics and antioxidative effect of cookies prepared with Curcuma longa L. powder (0, 1, 2, 3, 4%) substituted for flour. The pH of cookie dough decreased significantly in response to the addition of all levels of Curcuma longa L. powder (CLP). However, there were no significant differences in dough values among the test groups. Furthermore, when the spread factor values were compared among the groups, they were found to be inversely proportional to the CLP concentration. In addition, Hunter's color L value significantly decreased with increasing CLP content, whereas the a and b values increased. According to textural measurements, substitution of 1~4% for CLP resulted in increased hardness, cohesiveness, springiness, and brittleness when the samples were compared to the control. The results of sensory evaluation showed that the cookies containing 2% CLP had the highest scores. The acid value, peroxide value, and thiobarbituric acid value were all lower in cookies with 2% and 3% CLP than in cookies made with 4% CLP and control cookies.

The purpose of this study was to investigate the quality characteristics of fish paste added with different amounts (0%, 0.5%, 1%, 1.5%, and 2%) of spirulina powder. Specifically, moisture content, pH value, color value, texture value, total polyphenol content, DPPH radical scavenging activity, and sensory evaluation were measured in the samples. The moisture content of the fish paste added (0.5%, 1%, 1.5%, and 2%) ranged from 68.60% to 69.03%, and the increased amounts of spirulina powder in the fish paste tended to decrease the pH value. For the Hunter color values, the L, a values of surface and inside of the fish paste decreased with increased amounts of spirulina powder. The b values of the fish paste increased with increased amounts of spirulina powder. In the texture meter test, the hardness, gumminess, and adhesiveness decreased with the increased amounts of spirulina powder, and chewiness of group adding spirulina powder was measured lower than control. Springiness of the fish paste did not appear statistically significantly different among the samples according to the increased amounts of spirulina powder. Total polyphenol content of fish paste added with spirulina powder increased with increased amounts of spirulina powder, and DPPH radical scavenging was heightened according to increased amounts of spirulina powder. In sensory evaluation, the addition of 1% spirulina powder had the best score in odor, texture, taste, and overall preference. These results suggest that spirulina powder can be applied to fish paste to increase quality, preference, and functionality.

Comminuted sausages with reduced fat (25-0%) and increased moisture (19-44%) combinations were manufactured, and their chemical composition, and physico-chemical, textural and sensory properties were determined for the selection of the most palatable sausage treatment. The moisture and fat contents of the comminuted sausages varied from 55-79% and 26.4-2.14%, respectively, whereas, the protein content was relatively constant at 13.5-14.5%. Expressible moisture (EM, %) decreased with increased fat addition, and the high-fat control sausage (~25% fat) had lower EM than those with lower than 15% fat addition. Increased fat level also increased Hunter L values (lightness) of sausage samples taken from the core, and differences in lightness were observed between 15 and 25% fat level at the initial mixture. Sausages without fat addition had different textural characteristics from high-fat control sausages in most texture profile analysis (TPA) values. However, no differences in TPA values were observed among treatments with added fat (<25%) in the formulation. Results of the sensory evaluation showed that the most appropriate fat content of comminuted sausages to have better sensory properties ranged from 15-20% of added fat at the initial mixture. These results also indicated that decreased fat and increased moisture contents produce sausages with higher EM and lower lightness. Comminuted sausages without fat addition had different textural characteristics from the high-fat control.

This study was conducted to investigate the applicability of gamma irradiation for improving the quality of paprika and Japanese apricot extract-treated nitrite free pork jerky. Pork jerky was gamma-irradiated at 0, 3, 5, 7 and 10 kGy and physiochemical properties such as proximate composition, 2-thiobarbituric acid (TBARS) values, color stability, texture, and sensory property were then evaluated. The results showed that the treatment of paprika and Japanese apricot extract to the pork jerky increased Hunter color value and texture property and at the same time decreased TBARS values. When gamma irradiated, natural pigment extract-treated pork jerky did not produce any change in its proximate composition (moisture, crude protein, crude lipid contents), and TBARS values. However, the redness (a-value) of pork jerky increased as the irradiation dose increased, whereas shear force of pork jerky was decreased. Sensory result showed that gamma irradiation induced to decrease the sensory scores. Therefore, these results suggest that gamma irradiation and the addition of paprika and Japanese apricot extracts could be an effective mean to improve color and texture of restructured pork jerky without use of nitrite.

This study aimed to determine optimum leaves per shoot in 'Campbell Early' grape through investigating changes of fruit quality after veraison 70~75 berries of first cluster and 35~40 berries of second cluster at 30 days after full bloom. Soluble solids content (SSC) increased dramatically during 28 days after veraison and afterwards it was stabilized. 15 leaves per shoot treatment showed fast increase of SSC from early veraison and reached to over 16.0oBx at 28 days after veraison. No considerable increase of SSC were occurred on either 5 or 0 leaves per shoot treatments after veraison. Titratable acidity (TA) was decreased continuously during 28 days of berry ripening in the all treatments. In 15 leaves per shoot treatment, TA decreased fast during first 7 days after veraison and continuously decreased to 0.5% by harvest time. While, 5 and 0 leaves per shoot treatments showed TA decrease slightly only at the early veraison. Hunter L and b values of 15 leaves per shoot treatment decreased fast during first 7 days of veraison, and gradually decreased by 14 days, whereas Hunter a value increased fast during the first 7 days from veraison. Total anthocyanin content in 15 leaves per shoot treatment increased fast from 7 days of veraison and the increase became slow after 28 days of veraison. Other treatments showed no significant difference from veraison to harvest time.

The purpose of this study was to evaluate the quality of castella added with different concentrations (0%, 5%, 10%, and 15%) of Panax ginseng sprout powder. The specific gravity of castella made with 15% ginseng sprout powder was the highest (0.65), and baking loss rate was highest well. However, the height and weight of castella were highest in the control. The pH of castella decreased with increasing levels of Panax ginseng sprout powder, whereas sugar content of castella did not show significant differences. The Hunter L, a, and b values of crust decreased as the concentration of Panax ginseng sprout powder increased. The Hunter L and a values of crumb decreased as the concentration of ginseng sprout powder increased, whereas b values of crumb increased. The gumminess and chewiness of castella increased by addition of Panax ginseng sprout powder, whereas cohesiveness of castella decreased. The hardness and springiness of castella did not show significant differences. In the sensory evaluation, crust color, crumb color, aroma and moistness did not show significant differences among samples while sweet taste, and chewiness were highest in the control group. The overall acceptability of castella added with 5% Panax ginseng sprout powder was the highest. Therefore, the results suggest that castella added with 5% ginseng sprout powder could be helpful for improving physical quality and taste.
