This study was carried out to extract ginsenosides in by-products from honeyed red ginseng. Response surface methodology (RSM) was used to optimize the extraction conditions. Based on D-optimal design, independent variables were ethanol (extraction solvent) concentration (30-90%, v/v), extraction temperature ($25-70^{\circ}C$), and extraction time (5-11 h). Extraction yield (Y1) and total ginsenosides (Y2) in the extract were analyzed as dependent variables. Results found that extraction yield increased with increasing extraction temperature and time, whereas it was decreased with increasing ethanol concentration. Similar trends were found for the content of ginsenosides in the extracts, except for ethanol concentration, which was increased with increasing ethanol concentration. Regression equations derived from RSM were suggested to coincide well with the results from the experiments. The optimal extraction conditions for extraction yield and total ginsenosides were an extraction temperature of $56.94^{\circ}C$, ethanol concentration of 57.90%, and extraction time of 11 h. Under these conditions, extraction yield and total ginsenoside contents were predicted to be 84.52% and 9.54 mg/g, respectively.

This study was conducted to investigate the effects of the gloss of a product's packaging on purchase intention and the mediating role of perceived corporate eco-friendliness and perceived quality in food area. The participants were randomly assigned to product package condition (glossy vs. matte) and after observing ketchup and potato chips, they responded to questions on about perceived corporate eco-friendliness, perceived quality, and purchase intention. The participants reported their opinion that companies that manufactured matte package products would likely use more organic ingredients and would be more eco-friendly than companies that manufactured glossy package products. The more the participants perceived a company to be eco-friendly, the better they evaluated the company's product quality and the higher their purchase intention. This study has theoretical and practical implications, in that it extends the study of the product package in relation to its effect on corporate image, and it proposes a practical use of matte product package for improving the eco-friendly image of the company. Limitations and further research were also discussed.

Multiple lines of study have shown that Acanthopanax species have anti-oxidant and chemopreventive effect. However, the suitability of Acanthopanax sessilifloru fruit (Ogaza) as a functional food source remains to be investigated. Therefore, we have investigated the effect of Ogaza as an anti-oxidant and anti-inflammatory substance. The phenolic content of Ogaza is 56.1${\pm}$5.2 mg gallic acid equivalents (GAE) per 1 g of Ogaza. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging effects of Ogaza extract at 0.25, 0.5, 1, or 2 mg/mL were 34.0, 73.0, 194.3, or 339.7 $\mu g$/mL vitamin C equivalent antioxidnat capacity (VCEAC), respectively. Ogaza extract (1 or 2 mg/mL) inhibited LPS-induced TNF-$\alpha$ production (decrease of 22${\pm}$2% or 19${\pm}$6%, respectively). It also inhibited LPS-induced IL-6 production (decrease of 18${\pm}$2% or 24${\pm}$3%, respectively). In addition, Ogaza extract (0.25, 0.5, 1, or 2 mg/mL) inhibited COX-2 luciferase activity (decrease of 80${\pm}$1%, 83.${\pm}$7%, 96${\pm}$4%, or 98${\pm}$2%, respectively). Overall, these results indicated that Ogaza is promising as a functional food source due to its antioxidant and anti-inflammatory effects.

This study was carried out to investigate the effect of NaCl, pH and phosphate on the functional properties of a mixed system of plasma protein and myofibrillar proteins. The solubility of plasma protein, myofibrillar protein and the mixture (plasma+myofibrillar protein) increased according to the increase of NaCl concentration ($0{\sim}4%$) and pH $pH4{\sim}8$). The solubility, emulsifying activity and capacity of the mixture were lower than those of plasma protein, whereas higher than those of myofibrillar protein. The gel strength of the mixture and myofibrillar protein showed a significant increase when NaCl concentration was increased from 2 to 3%. The gel strength of myofibrillar protein increased about four times when 0.3% polyphosphate added to the sample containing 2% NaCl, whereas the moisture loss of the mixture and myofibrillar protein decreased significantly. The gel strength of plasma protein, myofibrillar protein and the mixture increased slightly at $3{\sim}5%$ protein concentration, whereas the gel strength of those increased significantly as the protein concentration increased from 5 to 9%.

The aim of this study was to investigate the change of volatile aroma compounds in kimchi during fermentation, before and after drying process. Also, the encapsulation effect of cyclodextrin on volatiles during the drying process was examined. GC-MS was used for detection and identification of volatile compounds. During kimchi fermentation, in the early stage, dimethyl sulfide, carbon disulfide were detected as major compounds and after 7 days several sulfur compounds, dimethyl disulfide, methyl 2-propenyl disulfide, allyl methyl sulfide, and di-2-propenyl disulfide bacame the major volatiles. After vacuum-drying, the kimchi powder lost 11 compounds but still retained 13 volatiles of which major compounds were dimethyl sulfide, acetaldehyde and methanethiol. In order to keep volatiles in kimchi powder along with the drying process, 0.25-1.0% cyclodextrin was added in kimchi and dried-kimchi was prepared by using vacuum dryer. Cyclodextrin acted as an encapsulation agent for aroma compounds and it resulted in less loss of volatiles during drying process. Addition of cyclodextrin will permit industry-scale production of dried-kimchi powder with less loss of aroma compounds.

The objective of this study was to increase the efficiency of starch extraction from potato sludge by different concentration of food-grade hemicellulase. The potato sludge, which is a by-product of potato processing industry, was treated with food-grade hemicellulase. Starch extraction efficiency displayed no significant difference in hemicellulase concentration. The purities of potato starch increased from 83.40 to 95.91, 97.44, 95.58, and 97.79%, with treated 0.5, 0.75, 1.0, and 1.5% hemicellulase, respectively. The physicochemical properties of the starches, such as granule structure, particle size, pasting, and thermal transition, were not affected by the concentration of hemicellulase. These results indicate that food-grade hemicellulase treatment is an efficient method for starch extraction from potato sludge.

그간 농식품부에서는 세계 여러나라와의 협상을 통해 2021년 6월 기준 홍콩, UAE, 캄보디아, 말레이시아로 수출 가능국을 확대한 것은 사실이나 2015년 한우고기 홍콩 첫 수출 이후 타 국가의 수출실적은 전무한 상황이다. 우리나라의 경우 쇠고기 수출 관련 할랄 인프라가 전무한 것이 가장 큰 문제이지만 더불어 할랄 시장에 대한 이해도와 시장상황에 대한 자료가 부족하여 관련 농가 및 업체들이 투자를 꺼려하는 것도 문제점 중 하나로 지적되고 있다. 본 연구팀은 세계 할랄 시장의 큰 축을 담당하고 있는 UAE, 말레이시아 중 할랄 도축관련 비관세 장벽이 비교적 낮은 말레이시아의 시장조사 및 관련기관 인터뷰를 실시하여 말레이시아 시장에서 한우고기의 가격경쟁력을 분석하였다. 조사·분석 결과 한우고기 1++등급의 경우 수출 조건(냉장/냉동) 및 경로(항공/해상)와 상관없이 사태, 앞다리를 제외한 모든 부분육에서 가격경쟁력이 있는 것으로 나타났다. 한우고기 1+등급의 경우 수출 조건(냉장/냉동) 및 경로(항공/해상)와 상관없이 사태, 앞다리를 제외한 모든 부분육에서 가격경쟁력이 있는 것으로 나타났다. 한우고기 1등급의 경우 수출 조건(냉장/냉동) 및 경로(항공/해상)와 상관없이 등심, 채끝 부분육에서 가격경쟁력이 있는 것으로 나타났다.
