  • This study is to evaluate moisturizing effect and durability of UV A/B blocking activity with multiple (W/O/W) emulsion system. Most of the sun protective products come to be hot issue having both high SPF and long-lasting activity as using special products when is going out, mountain climbing and sports. Also, many consumers prefer the products which have the excellent waterproofing activity of sun care cosmetics as well as the non-sticky feeling that carried out the study of the sensorial science and texture preference. Therefore, development of the specific formulation using this multiple (W/O/W) emulsion technology, it has O/W type hydro skin feel having soft and moist texture when it is treated on the skin. Finally, this formulation is instantly changed to W/O type feel after adsorbed into the skin. The purpose of this study is to get high SPF lasting effect having high water resistance tactivity with high functional multiple (W/O/W) emulsion cream. We used major ingredients, UV-B absorbers were selected with ethylhexyl methoxycinnamate, isoamyl-p-methoxycinnamate, ethylhexylsalicylate, and octocrylene, UV-A absorbers were selected with butylmethoxydibenzoylmethane, bis-ethylhexyloxyphenol methoxy phenyltriazine. SPF effect of O/W type cream was 34.1. SPF effect of W/O/W type cream was 40.6 (increased about 19%). Water resistance effect after 4 hours, SPF effect of O/W type cream was 3.6 (quickly drop down). SPF effect of W/O/W type cream having 81.0 % waterproofing effect was 32.7 (decreased about SPF 7.9). Moisturizing effect of O/W cream at first was superior comparing multiple emulsion. But after 3 hours quickly was drop-down. Moisturizing effect of multiple emulsion was high comparing O/W type and other sun block creams after 4 hours was constantly maintaining water-content.

  • This study was conducted to develope a new type of ready-to-eat smoked Sebastes schlegeli product with high acceptability and extended shelf-life. A Sebastes schlegeli was salted at 4% salt concentration for 6 hr at $4^{\circ}C$. The cold smoking conditions for the salted Sebastes schlegeli consisted of drying for 2 hr at $22{\sim}24^{\circ}C$ followed by smoking for 2 hr at $22{\sim}24^{\circ}C$. The warm smoking conditions for the salted Sebastes schlegeli consisted of drying for 2 hr at $22{\sim}24^{\circ}C$, smoking for 2 hr at $22{\sim}24^{\circ}C$, and smoking again for 30 min at $47{\sim}50^{\circ}C$. The rancidity of the smoked Sebastes schlegeli did not change after 1 year storage at $-20^{\circ}C$ by monitoring the iodine value, peroxide value, and acid value. The number of viable cells in the cold and warm smoked samples were counted as $7.4{\times}10^5$ and $6.2{times}10^5$ CFU/g, respectively. Viable cells were not detected after 1 year of storage at $-20^{\circ}C$. The sensory evaluations of the processed Sebastes schlegeli showed that elastic texture increased with smoking as compared to with salting. There were no significant differences between cold and warm smoking in terms of sweetness, elastic texture, color, and smoke flavor. However, for overall acceptability, preference were in the oder of cold smoked, warm smoked, and salted.

  • This study was conducted to investigate the effects of dietary quercetin on feed utilization, blood parameters, and meat quality of Korean native goats. Totally sixteen Korean native goats, 15 kg of average BW aged at 7 months, were employed in the experiment with eight replicates per treatment. One group was fed quercetin at 200 mg/kg level and the other group was fed none as control for 15 days. Dietary inclusion of quercetin did not affect feed intake, water intake, and the amount of urine and feces. Digestibilities of crude fat, NDF, and ADF for 5 days were not affected, but digestibility of crude protein was increased by the dietary inclusion of qurecetin (P<0.05). Quercetin increased rumen total VFA, propionate, and butyrate significantly (P<0.05). Acetate/propionate ratio (A/P) in the quercetin treated group was significantly higher than control. 2,2-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) ($ABTS^+$) reducing activity of the loin from goat fed quercetin was higher than that of control. Sensory analysis conducted at 24 hr post mortem revealed that color, texture, and overall acceptability of the loin from goat fed quercetin were significantly preferred to that of control. Feeding quercetin did not influence pH, water holding capacity, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, TBARS value, and fatty acid composition of the loin significantly. In conclusion, the dietary inclusion of quercetin increased the digestibility of crude protein, rumen total VFA, propionate, butyrate, and A/P ratio. In addition the higher color and texture preference and ABTS+reducing activity of loin indicating some beneficial effect on enhancement of meat qualityin goats.

  • The aim of this study was to evaluate the quality characteristics and antioxidative properties of cookies supplemented with mulberry pomace (0%, 4%, 8%, 12%). The bulk density, spread ratio, and leavening rate of cookies decreased with increasing amounts of mulberry pomace. The lightness and b value (of the Hunter color system) decreased based on the amount of mulberry pomace. The pH of cookies decreased (acidity increased) with increasing mulberry pomace. The soluble solid content increased according to the amount of added mulberry pomace, but the amount of reducing sugars decreased. In texture analysis, cookies with 12% mulberry pomace had the highest hardness. Total phenol and flavonoid content increased according to the amount of mulberry pomace added. Antioxidant activities, such as DPPH radical scavenging, hydroxyl radical scavenging, ABTS radical scavenging, and FRAP were highest in cookies with 12% mulberry pomace. In the sensory evaluation, sensory scores for color, taste, flavor, texture, and overall preference were highest in cookies with 8% mulberry pomace. Thus, our results suggest that the optimum amount of mulberry pomace to add to cookies is 8%.

  • This study was conducted in order to determine the effect of autoclave and microwave treatments on cookies. Wheat dough was treated in an autoclave (30 min), a microwave (1 min), and both autoclave and microwave (30 min/1 min). The treated dough was baked or non-baked and cookies quality was assessed. The pH, moisture content, color, and texture were measured, and sensory evaluation was performed. The pH showed a slight increase when dough was treated in a microwave (before baking) and decreased in both the autoclave and autoclave/microwave (after baking) treatments. The moisture content showed a significant increase, compared to the control, in autoclave treatments. Regarding surface color of cookies, lightness was decreased in all treatments and redness was higher compared with the control, except for microwave (before baking), and yellowness was lower compared to the control, except for microwave treatment (after baking). Hardness, gumminess, chewiness, and shear force showed a significant increase when dough was treated in an autoclave/microwave (after baking) compared to the control. In the sensory evaluation, color, taste, texture, shape, and overall preference of cookies treated with an autoclave/microwave (after baking) showed a low score. These results suggest that autoclaving and microwaving may reduce the quality of bread and that preparation of countermeasures is necessary.

  • Perilla leaves powder was added to cookies to determine a practical use for the herb, which has been shown to have medical benefits and functionality. We examined the antioxidant activity and quality characteristics of cookies prepared with different amounts (as ratios of 0.5%, 1%, 3%, 5% to the total materials) of perilla leaves powder. The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenolic compound content in perilla leaves powder and cookies. The quality characteristics of the perilla leaves cookie were estimated in terms of the bulk density, pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations. While the bulk density and pH of the dough as well as total polyphenol contents and DPPH free radical scavenging activity of cookies significantly increased, the spread factor, loss rate, leavening rate and L value of the cookies decreased with increasing perilla leaves powder content(p<.05). The consumer acceptability scores for the $1{\sim}3%$ perilla leaves cookie groups ranked significantly(p<.05) higher than those of the other groups in appearance, taste, flavor, texture, and overall preference. This study suggests that perilla leaves powder is a good ingredient to increase the consumer acceptability and the functionality of cookies.

  • This experiment was conducted to research the effects of Yellow Clay(YC) on the sensory evaluation of cooked meat in broiler chicks. A total of 216 one day old broiler chicks were divided into 6 groups at random. The six groups are consisted of one control group, to which no YC was added, and 5 groups to which an amount of YC was differently added. Diets contained 0.5, 1.0, 2.0, 4.0 and 8.0% of YC and fed to the 5 group broilers for 6 weeks. The lightness of meat in the broilers treated with YC was significantly higher than that of the control group in after-cooking(P<0.05). Besides, the lightness of meat was higher after-cooking than before-cooking. The properties of hardness, gumminess and chewiness were significantly lowered in the groups treated with Yellow Clay, as the amount of Yellow Clay increased at before-cooking and after-cooking(P<0.05). The turbidity of stock was higher in the groups treated with Yellow Clay as the percentage level of Yellow Clay increased, compared with the control group(P<0.05). The acceptability of color, flavor, and texture of meat and stock was higher in the groups treated with Yellow Clay, when compared with that of the control group(P<0.05). In total, the group treated with the 4 percentage of Yellow Clay was the highest in the overall preference(P<0.05).

  • This study was designed to determine the optimal ratio of dropwort powder in castella by adding the powder at levels of 0, 3, 6, 9, and 12% respectively. The properties of the castella were analyzed by specific gravity, specific volume, color determinations, texture properties and sensory evaluation. The Specific gravity increased with increasing amount of dropwort powder. However, the specific volume decreased with increasing dropwort powder. For the color values, as more dropwort powder was added, the L-value decreased. The castella with 9% dropwort powder had a higher hardness, gumminess, and chewiness. A sensory panel perceived that the external and internal color of the castella become darker with the dropwort powder substitution and the grain size decreased with increasing amount dropwort powder, while sweet taste showed no significant difference. The order of overall preference was DP 9>DP 6>DP 12>CON>DP 3. Therefore, the substitution of 9% of wheat flour with dropwort powder was recommended in the production of castella.

  • In this study, we investigated the physical properties, color values of mixtures with starch from potato in preparing a cartridge for 3D printing using golden threadfin bream (Nemipterus virgatus) surimi as raw material. The results show that the hardness and gumminess of the surimi mixture added potato starch increased but cohesiveness decreased compared to the negative control. This means that the starch makes surimi stronger texture than the negative control. After 7 days of cold storage at 4 ℃, for unheated surimi, firmness is increased but adhesiveness is decreased. And among physical properties of surimi stored after heating, hardness and gumminess were decreased compared to before storage. Lastly, after storage for 7 days, the hardness and gumminess of fried surimi decreased compared to fried surimi before storage. As a result of sensory evaluation, texture, elasticity scent of surimi stored after heating were decreased but overall favorability was similar. Compared to the after storage, result of sensory evaluation of fried surimi, result of the before storage showed no significant differences. From these results, it is suggested that potato starch, which increases overall physical strength and have little effect on preference, can be used as an additive for golden threadfin bream surimi.

  • The combination of early heading time, maturing time and short grain-filling period is very important to develop early varieties in winter barley. The 4 parental half diallel crosses (parents, $F_1$s, $F_2$s) were cultivated at the field. The heading date was from April 3 to 26, maturing date from May 15 to 27 and grain-filling period from 31 days to 42 days, showing that the varietal differences about the 3 traits were remarkable. According to half diallel cross analyses, Dongbori 1 for heading time (late heading) was dominant, but Oweolbori (early heading) was recessive, showing partial dominance with high additive component of genetic variance. Dongbori 1 for maturing time was dominant, but Oweolbori was recessive, showing partial dominance with high additive variance. Reno for grain-filling period (short grain-filling period) was dominant, but Oweolbori (long grain-filling period) was recessive with additive, and partial dominance. There were highly significant mean squares for both GCA and SCA effects on the heading and maturing times, and GCA/SCA ratios for all traits were high, showing the additive gene effects more important. Sacheon 6 and Oweolbori had greater GCA effects for early heading and maturing times, and Dongbori 1 and Reno had greater GCA effects for late times. GCA effects were highly significant in $F_1$ and $F_2$ generations, showing high GCA/SCA ratios (7.02). The heading and maturing times in field were positively correlated with antifreeze proteins concentrations, accumulation, resistance to photoinhibition and winter survival, respectively) but the grain-filling period did negatively correlated with the trails.
