  • This study was performed to investigate how the addition of starch nanoparticles prior to whipping could affect the quality characteristics and stability of full-fat dairy cream. Starch nanoparticles were prepared by dry heating under mildly acidic conditions and added to dairy cream as amount of 1, 3, and 5% (w/w). The whipped cream's storage stability, viscosity, overrun, and droplet size were investigated in combination with various starch nanoparticle contents. The storage stability and apparent viscosity increased in parallel with the increasing starch nanoparticle content compared to the control. The mean size and homogeneity of the droplets in the whipped cream increased with higher starch nanoparticle addition levels. Even though the whipped cream overrun was reduced by the addition of starch nanoparticles, the 1% addition level exhibited a similar overrun value as the control.

  • A study was undertaken to examine the effect of the addition of coriander leaves(Coriandrum satovim L.) and brocolli stem powder addition on the quality attributes of pound cakes. Coriander leaves & brocolli stem powder was added to the batter, at a ratio of 10, 12.5 and 15%, respectively. The antioxidant activity was estimated by a DPPH free radical scavening activity, the total phenolic compounds content and flavonoid content in coriander leaves & brocolli stem powder and pounds cakes. Antioxidative activity had correlated highly with the total flavonoids contents of coriander leaves & brocolli stem powder of pound cakes, respectively(r=0.9096). The quality characteristics of coriander leaves & brocolli stem powder pound cakes were estimated in terms of the specific load volume, hardness, hunter value of crumb and crust, and the sensory quality of the cakes. The specific volume decreased significantly, with increasingly substituted level of coriander leaves & brocolli stem powder(p<0.01). The lightness was significantly decreased with increases in the coriander leaves & brocolli stem powder of pound cake crust and crumb(p<0.01). The hardness, chewiness and gumminess tended to reduce, and the cohesiveness decrease in both of powder. The consumer acceptability score for 10% coriander leaves & brocolli stem powder of pound cakes ranked significantly(p<0.01) higher than those of the other groups in taste, flavor and color. These results showed that coriander leaves & brocolli stem powder are good ingredients to increase the consumer acceptability and the health.

  • This study was performed to determine the effect of multilayered fish oil (FO) emulsion without or with trans-cinnamal-dehyde on pork patties. Multilayered FO (-primary, -secondary, -tertiary) emulsions were prepared using a layer-by-layer deposition technique with Tween 20, chitosan, and low methoxyl pectin, and were added to pork patties at the same concentration. Pork patties were then stored for 20 d in a refrigerator ($5^{\circ}C$) to study changes in quality. The results showed that the pH value of all samples significantly decreased but cooking loss increased during storage (p<0.05). However, water-holding capacity and moisture content showed no remarkable difference between treatments and storage periods (p>0.05). All pork patties containing multilayered FO (treated samples) showed higher values for lightness and significantly lower values for yellowness compared to control pork patties (untreated sample). Lipid oxidation was higher in treated pork patties than in control pork patties during storage. In addition, lipid oxidation and total viable bacterial count in pork patties decreased as the number of coating layers increased. However, hardness, cohesiveness, and springiness of all samples showed no significant change during storage (p>0.05) as compared to fresh pork patties. Furthermore, these did not remarkable change with addition of trans-cinnamaldehyde in all pork patties. From our results, we suggest that FO emulsion did not affect the texture characteristics of fresh pork patties, indicating that it could be used to improve the quality of pork patties by contributing high-quality fat such as unsaturated fatty acids.

  • This study evaluated the effect of the addition of pig skin gelatine powder with different levels on the chemical compositions, cooking characteristics, and sensory properties of tteokgalbi. Tteokgalbi was produced from products containing 0% (control), 1%, 2%, 3%, and 4% pig skin gelatine powder. The protein and moisture contents of samples increased with an increase of pig skin gelatin powder levels. In addition, the pH value and CIE $b^*$ values of uncooked and cooked samples increased with increasing amount of pig skin gelatin powder. However, cooking loss, diameter reduction, and thickness reduction of samples decreased with an increase of gelatin powder contents. The hardness, gumminess, and chewiness of samples increased with an increase of gelatin powder contents, and sensory evaluation of tteokgalbi containing 2~3% pig skin gelatin powder was the highest. Therefore, usages of pig skin gelatin powder can improve quality characteristics of tteokgalbi.

  • Objective: This study aimed to develop a value-added product concerning technological and sensory characteristics changes of the use of mechanically deboned poultry meat (MDPM) as meat replacer in lamb and mutton emulsion-type sausages (mortadella). Methods: Sausages were produced with lamb and mutton and with different contents of MDPM. Six treatments, using lamb or mutton and 0%, 30%, and 60% of MDPM in relation to the meat batter, were produced and analyzed for pH, proximal composition, calcium and residual nitrite content, water activity, 2-thiobarbituric acid reactive substances (TBARS), instrumental color and texture profile. The sensory profile of the mortadella's was also evaluated by acceptance test and check-all-that-applies (CATA) analysis. Results: The MDPM addition increased (p<0.05) fat, residual nitrite and calcium content in the all sausage formulations, but mutton sausage had (p<0.05) higher fat and lower moisture content than lamb sausage. The pH, water activity, TBARS index and color was not affected by MDPM additions, while the mutton sausages were significantly redder (higher $a^*$, $C^*$, and lower $h^{\circ}$) and darker (lower $L^*$) than lamb sausages. Adding up to 60% of MDPM reduced (p<0.05) sausages hardness and chewiness. Overall, the meat replacement by MDPM increased the sausages acceptance, but the mutton sausage with 30% of MDPM replacer were the most preferred. Consumers related that pink color, glossy appearance, poultry meat-like taste, soft texture, juicy and greasy mouth feel to all sausages contain MDPM according to CATA analysis. Conclusion: Mutton from culled ewes can be utilized for mortadella production with 30% replacement of lean mutton and fat by MDPM.

  • This study was aimed at investigating hepatic toxicity and immunomodulating effects of defatted methanol extracts of two kinds of medicinal plants, Rubus coreanus Miq. and Atractylodes japonica Koidz. in mice. Defatted methanol extracts of fruits of Rubus coreanus Miq. and rhizome of Atractylodes japonica Koidz. were added at the level of 0.5% or 5%(w/w) to cholesterol-supplemented AIN-76 diet. Each diet was fed to 8 ICR male mice for 30 days. Weight gain and food efficiency ratio of the mice fed 5.0% extract of Rubus coreanus Miq. were significantly lower than those of the mice fed 0.5% extract Relative liver weight and activity of plasma alanine aminotransfernse were significantly increased only in the mice fed 5% extract of Atractylodes japonica Koidz. compared with the others. Splenocyte proliferation was not significantly different between the groups fed 0.5% or 5.0% extract of Rubus coreanus Miq. However, splenocyte proliferation was significantly decreased in the mice fed 5.0% extract of Atractylodes japonica Koidz. compared with that in the mice fed 0.5% Production of interleukin-2 by splenocytes from the mice fed 0.5% extract of Atractylodes japonica Miq. was significantly higher than the control value and it became lower with 5.0% dietary level. Secretion of $interferon-\gamma$ was not significantly different among groups. In conclusion, the defatted methanol extract of Atractylodes japonica Koidz. was likely to exert immunomodulating effect at the level of 0.5% but it may exert adverse effects on immune and liver functions at the level of 5.0%.

  • The significance of the image content industry, as a flagship industry of the cultural content industry, is emerging globally as a high value-added trend. Since the movie industry has diverse related industries along with a positive spillover effect from cultural and economic perspectives, it ultimately strengthens national brands as well as national competitiveness. As a national strategy cultural content industry, the movie industry in each country around the world utilizes its own diverse self-protective systems. The Korean movie industry has emerged as a 10 million-strong movie-goer market; however, in reality, it is vulnerable to high film production costs and utility. The current domestic media market demands a new paradigm through the media industry as a whole; nonetheless, it is inherently limited to past film production and distribution channels. In this study, I seek to evaluate the status quo and propose a new direction for the Korea movie industry.
