  • In the pursuit of practical usage for Codonopsis lanceolata and development of functional processed food material, the research on the product characterization is being performed through the manufacturing of Yanggaeng which is extracted from the Codonopsis lanceolata skin concentrate. By adding Codonopsis lanceolata skin extracts (0, 40, 60, 80, 100%) to the product, the chemical property characterization and organoleptic test of the produced Yanggaeng are being conducted. The scavenging effects on DPPH free radical have a significant proportional relationship with the addition of Codonopsis lanceolata skin extracts as 61.30 for 100% added group as compared with 52.72 for the null-addition group. It is considered that the antioxidative activity increases with the addition of the Codonopsis lanceolata skin extraction as the SOD similar activity rate was increased to 49.23% from 39.31%, the flavor preference was ranked as 80%>60%>0%>100%>40% showing that 60~80% of Codonopsis lanceolata skin extraction addition seems to be the proper amount.

  • The purpose of this study was to propose optimal mixing proportion by adding stevia in powder form, which are low caloric and high intensity sweetener to cookies, and to determine the characteristic of product. It reduced the average sugar content of cookies to 50%, processed stevia powder, add them in 2, 4, 6, and 8% to make cookies and measured various product characteristics, including anti-oxidant activity. The antioxidant activity was highly correlated with the total phenolic composition of stevia cookies (r=0.967). Total phenolic contents and DPPH free radical scavenging activity of cookies significantly increased with increasing stevia powder. The bulk density of the dough, spread factor and the hardness, total polyphenol contents and DPPH free radical scavenging activity of cookies significantly increased with increasing stevia powder, while the pH of the dough, and L values of the cookies decreased with increasing stevia powder content (p<0.001). Additionally, the consumer acceptability scores for the 4% stevia cookie groups ranked significantly (p<0.001) higher than those of the other groups in color, taste, flavor, sweetness and overall preference. All the take together, the results of this study suggest that stevia powder is a good ingredient for increasing the consumer acceptability and the functionality of cookies.

  • Sodium chloride is used to improve various properties of processed meat products, e.g., taste, preservation, water binding capacity, texture, meat batter viscosity, safety, and flavor; however, many studies have shown that sodium chloride increases the resistance of many foodborne pathogens to heat and acid. Listeria monocytogenes has been isolated from various readyto- eat (RTE) meat and dairy products formulated with sodium chloride; therefore, the objective of this paper was to review the effects of sodium chloride on the physiological characteristics of L. monocytogenes. The exposure of L. monocytogenes to sodium chloride may increase biofilm formation on foods or food contact surfaces, virulence gene transcription, invasion of Caco-2 cells, and bacteriocin production, depending on L. monocytogenes strain and serotype as well as sodium chloride concentration. When L. monocytogenes cells were exposed to sodium chloride, their resistance to UV-C irradiation and freezing temperatures increased, but sodium chloride had no effect on their resistance to gamma irradiation. The morphological properties of L. monocytogenes, especially cell elongation and filament formation, also change in response to sodium chloride. These findings indicate that sodium chloride affects various physiological responses of L. monocytogenes and thus, the effect of sodium chloride on L. monocytogenes in RTE meat and dairy products needs to be considered with respect to food safety. Moreover, further studies of microbial risk assessment should be conducted to suggest an appropriate sodium chloride concentration in animal origin foods.

  • This study examined the effects of adding Pleurotus ostreatus, Agaricus bisporus and Flammulina velutipes on the quality characteristics of cookies and multiple purposes of wheat powders. The water content, crude protein content, mineral content, color value and sensory evaluation of mushroom cookies and multiple purposes of wheat powders were measured. In the case of cookies, the water content was 1.10-1.24% and crude protein content was 8.20-9.80%. General preferences, such as appearance, color, taste and texture, increased when mushroom was added to the cookies, especially flavor, which showed a much higher preference. In the studies where mushroom was added to wheat powders, the water content was 0.57-0.92% and crude protein content was 11.90-12.80%. The addition of mushroom to both of the cookies and multiple purposes of wheat powders resulted in a remarkable increase in the mineral content, especially Fe, K. In addition, an increase in the amount of added mushrooms resulted in an increase in the hunter L and a values; however, this also resulted in a decrease in the b value.

  • To develop processed meat products of pheasant, cut-up parts of pheasant carcass was analyzed, and eight different pheasant meat products were prepared and evaluated for sensory qualities. The average live weight of pheasant was 1,089.2g, and the ratio of carcass to live weight was 75.6%. The cut-up part ratios of breast, leg, neck, back and wings to carcass weight were 33.4%, 22.5%, 5.0%, 4% and 9.5%, respectively. The chemical compositions of breast and leg meat were shown to be moisture of 73.72% and 75.58%, protein of 25.31% and 22.69%, fat of 0.28% and 0.83%, and ash of 0.84% and 0.90%, respectively. Sensory evaluation of eight different meat products of pheasant revealed that all products of pheasant meat, except frankfurt sausage, received equal or better taste score compared with products of chicken or pork, and flavor score except pressed ham and salad. Color, binding ability and particle perception scores of pheasant meat products were equal or superior to those of respective meat products of chicken or pork. The present results suggest that pheasant meat has a potential to be utilized for various value-added products and that the meat bun is the most promising product of pheasant meat. A reinforcement of color, binding ability and particle perception of meat products of other species could also be expected by addition of pheasant meat to them.

  • Oriental melon has been increased in production amount, but its processed food was not made in spite of the fact that shelf-life of the fresh fruit is short. This study was carried out to develop a dried product with no use sulfur treatment. Fresh melons were peeled, cut into 6 pieces, and soaked to the following pretreatments soaking in sugar syrup(SS), sodium chloride(SC), ascorbic acid(AA) and sodium polyphosphate(SP). After preatreatments the melon pieces were dried by hot air drying at 5$0^{\circ}C$ for 9 and 12 hours, and the dried melons were air blown at $25^{\circ}C$ for 1 day. The dried samples were evaluated for moisture content, texture, rotor, and sensory quality. The moisture content of dried melons soaked in SS and SC were lower than those that were soaked in AA and SP after hot air drying. The melons dried for 12 hours were high in hardness, gumminess, chewness and adhesiveness and excellent in sensory evaluation compared to 9 hours. The "L" value of SS was higher and the "a" value was lower in Hunter color. And SS treatment inhibited browning of the dried melon and improved sensory characteristics in color, flavor, texture and taste. Sucrose concentration had no significant effect on color, hardness and sensory score in banal product. The combination of SS with SP represented a highly effective antibrowning treatment for the dried melon and the product was kept in good color for 3 months at room temperature.at room temperature.

  • This study was conducted to find out the bakery processing suitability of maca and to develop rice-based processed foods. We investigated the antioxidant activity and physicochemical properties of rice cookies prepared with the addition of maca (Lepidium meyenii) powder (1%, 2%, 3%, and 4% of the total materials). We observed an increase in the total polyphenol and flavonoid content, and DPPH-ABTS+ radical scavenging activity of the rice cookies as the proportion of added maca powder increased (p<0.05). The quality characteristics such as the "a" value, "b" value, and the hardness of the cookies increased with an increase in the proportion of maca powder (p<0.05) in the cookie, whereas the moisture content, pH of the dough, spread ratio, loss rate, leavening rate, and "L" values showed a significant decrease (p<0.05). In the sensory evaluation results, consumer acceptability showed a significantly higher value in the 2% maca cookie group (p<0.05), and the characteristic intensity rating (color, flavor, bitterness) increased as the proportion of maca added to the cookie increased (p<0.05). Therefore, this suggests that adding 2% maca powder as the functional ingredient in rice cookies can result in rice bakery products with excellent qualities.

  • This study judged that although milk with various properties is currently being released, the growth rate of the milk market has not changed significantly, and the reason for this is that a substitution relationship has been formed between existing white milk and milk with various properties and they are competing with each other. The purpose of this study was to provide implications for the future growth of the milk market by identifying the relationship between diversified milk attributes. As a research method for this purpose the own price elasticity, cross-price elasticity, and expenditure elasticity of each attribute were derived through the LA/AIDS demand system model, and an analysis of consumers' milk purchasing factors was conducted through factor analysis. Based on the analysis results, it presented implications for growth in the milk market, such as expanding products with great differentiation in attributes such as flavor, plant and lactose-free properties, establishment of marketing strategies targeting consumers with children, and expansion of online malls.

  • 시중에서 유통되는 부분 가공 원예산물의 세균밀도는 매우 높아 청결 상태가 불량하였다. 작물별로는 깐마늘에 세균밀도가 낮았으며 기타 작물의 경우 미생물 밀도는 $10^8$ 이상이었다. 특히 고사리의 경우 가장 세균 밀도가 높을 뿐아니라 이물질이 혼입된 경우도 있었다. 오존수 처리반응은 작물의 유형에 따라 차이를 나타내었는데 근채류인 우엉과 연근은 변색을 방지할 뿐아니라 살균 효과로 세절한 작물의 유통성을 향상시킬 수 있었으나 $0.3mg{\cdot}L^{-1}$ 농도에서 5분 이상 처리할 경우 오히려 불리하였다. 양상추의 경우 $0.3mg{\cdot}L^{-1}$에서 2분을 초과하여 처리할 때 조직이 물러지고 변색이 더욱 심하여 처리시간과 농도에 대한 구체적인 검토가 필요하였다. 건조나물의 경우 살균효과 뿐아니라 유통 중 세균 증식에 따른 이취 발생을 억제하는데 효과적이었다. 이러한 효과는 조직이 두꺼운 고사리보다 얇은 취나물에서 더욱 뚜렷하였다. 본 연구에서 얻어진 결과를 살필 때 건조나물을 비롯한 연근, 우엉 등의 작물에 대하여서는 실용화 가능성이 있는 것으로 판단된다.
