The purpose of this study was to assess consumption and satisfaction with fresh-cut produce in Korean adults. In this study, an online survey November 9~13, 2020 was conducted with 982 Korean adults age 19~64 (490 males and 492 females) with experience in purchasing fresh-cut produce in the past year. Among all respondents, the percentage with experience in buying 'washed or peeled vegetables' was the highest (71.18%), followed by those in buying 'packaged salads/sprouts/ssam vegetables' (64.15%), 'pre-cut fruits/fruit cups' (59.98%), 'pre-cut or minced vegetables' (56.01%), and 'washed or peeled fruits' (53.67%), respectively. Among the types of fresh-cut produce, 'packaged salads/sprouts/ssam vegetables' showed the highest satisfaction score at 3.73 pts, and the overall satisfaction score of fresh-cut produce consumption was also 3.73 pts. Compared to male respondents, female respondents showed a significantly higher percentage of respondents that purchased 'packaged salads/sprouts/ssam vegetables' (p=0.0409), significantly higher satisfaction scores (p=0.0124), and a higher percentage of respondents considering 'freshness' important when purchasing (p<0.0001). Additionally, the group with high household income comprised a significantly higher ratio of respondents considering 'eco-friendly or organic status' important. The study results may facilitate identify areas for improvement of fresh-cut produce in the future.

This study was conducted to investigate the bioconversion of ginsenosides as well as anti-inflammatory activities of fresh ginseng Kkakdugi during fermentation. Fresh ginseng Kkakdugi reached proper ripeness, pH 4.30, and acidity 1.69% at $15^{\circ}C$ after 10 days. Lactic acid bacteria grew until reaching $1.10{\times}10^9CFU/mL$ after 20 days of fermentation, and ${\beta}$-glucosidase activity increased from 1.154 to 1.885 units/g. The bioconversion of ginsenosides was confirmed based on increased content of Rg3, an aglycone, from 0.13 to 0.17 mg/g during fermentation through HPLC. Fresh ginseng Kkakdugi did not display cytotoxicity up to the concentrations of $80{\mu}g/mL$, regardless of ripening period. Nitrite production and expression of inflammation-related proteins, iNOS and COX-2, decreased in a dose-dependent manner regardless of ripening period. From these results, fresh ginseng Kkakdugi showed the bioconversion of ginsenosides to aglycone during the lactic acid fermentation as well as an anti-inflammatory effect through the reduction of NO production and iNOS and COX-2 expression.

매실(Prunus mume)의 착즙과 건조 특성에 동결 전처리가 미치는 영향을 조사하기 위하여, 매실을 동결처리($-20^{\circ}C$)하거나 처리하지 않고 착즙수율과 주스의 품질특성 및 건조속도와 분말의 품질특성을 각각 측정하였다. 매실의 착즙수율과 건조속도는 동결처리구가 무처리구보다 유의적으로 높은 수준을 나타내었다. 압착주스와 건조분말의 L과 b값 및 a값은 동결처리구가 무처리구보다 유의적으로 낮고 높은 수준을 각각 보였다. 압착주스와 건조분말의 유리당과 유기산 함량은 동결 전처리에 따른 유의적인 차이를 나타나지 않았다. 주스의 가용성 고형분 함량, 적정산도 및 pH는 동결 전처리의 영향을 받지 않은 것으로 나타났다. 이로써 동결 전처리는 매실의 착즙과 건조 효율을 증대시킬 수 있는 유효한 방법이지만 착즙액과 건조분말의 갈변도가 높은 문제점이 있는 것으로 확인되었다.

The effect of post-cut vanillin treatment at high concentrations on changes of quality and microorganism in fresh-cut apples was studied. Apples (Malus domestica Borkh. cv. Fuji) were sliced, treated by dipping in different vanillin solution, 0, 40, 80, and 120 mM, packed in polyethylene bag, and then stored for up to 3 weeks at $4^{\circ}C$. Changes in total aerobic bacteria, yeast and molds, browning, soluble solids, and titratable acidity during storage were investigated. Growth of total aerobic bacteria throughout storage was strongly inhibited by vanillin regardless of treatment concentrations. Growth of yeast and molds was inhibited by vanillin of all concentrations until 2 weeks of storage. Levels of browning index, soluble solids, and titratable acidity were not significant difference among the treatment conditions until 2 weeks of storage. However, when stored for 3 weeks, browning index increased more at 80 or 120 mM vanillin, while soluble solids and titratable acidity more be decreased by 120 mM vanillin as compared with other treatment conditions. These results show that the usage of vanillin in processing of fresh-cut apples had a limitation for maintaining quality.

The dielectric properties, dielectric constant (${\varepsilon}‘$) and loss factor (${\varepsilon}’$), of skin and pulp of fresh ginseng were measured from $25^{\circ}C$ to $67^{\circ}C$ using an open-ended coaxial probe technique for 915 MHz and 2450 MHz. Pulp and skin had dielectric constant of $30{\sim}64$ and loss factor between 10 and 20, each variable having a respective frequency dependence typical of materials with high water content. Although the loss factor was nearly constant, the dielectric constant increased as moisture content increased. The dielectric constant of ginseng pulp increased as temperature increased (temperature ${\leq}56^{\circ}C$), but any significant differences were not found in skin dielectric properties. Penetration depth for fresh ginseng were about 2 cm at 91.5 MHz and 1cm at 2450 MHz.

Akcakatik cheese (yogurt cheese) is produced by drying strained yogurt with or without adding cloves or black cumin. The main objective of this study was to detect the properties of both fresh and ripened Akcakatik cheeses and to compare them. For this purpose the biogenic amine content, volatile flavor compounds, protein degradation level, chemical properties and some microbiological properties of 15 Akcakatik cheese samples were investigated. Titratable acidity, total dry matter, NaCl, total nitrogen, water soluble nitrogen, ripened index, histamine, diacetyl and acetaldehyde levels were found to be higher in ripened cheese samples than in fresh cheese samples. On the other hand, the clove and black cumin ratios were found to be higher in the fresh cheese samples. Sodium dodecyl sulphate polyacrylamide gel electropherograms of cheese samples showed that protein degradation was higher in ripened cheese samples than in fresh samples, as expected. The dominant Lactic acid bacteria (LAB) flora of Akcakatik cheese samples were found to be Streptococcus salivarius subsp. thermophilus and Lactobacillus delbrueckii subsp. bulgaricus.

This study aims to confirm the appropriateness of fruit and vegetable sales at military commissaries, with the purpose of enhancing the physical health and morale of military personnel. In order to achieve this objective, we examined the actual conditions of fruit and vegetable sales at military commissaries and analyzed the soldiers' awareness of fruit and vegetable sales through questionnaire surveys. The conclusions of this study are as follows: Firstly, fresh fruits and vegetables were not sold at military commissaries. Secondly, soldiers acknowledged the need for the consumption of fruits and vegetables and strongly expressed the desire for these fresh food products to be sold at military commissaries. Although the ROK Navy privatized military commissaries for the purposes of increasing management efficiency of national defense and strengthening combat power by transferring PX salesclerk soldiers to join combat personnel, this effort produced a negative effect of price increase. The following are proposals for improving this condition: fruit and vegetable products should be introduced to military commissaries through military welfare funds; fresh food markets should be established by closely cooperating with the local community's agricultural producers; processed fruit and vegetable product (dry, frozen, airtight packaged, etc.) sales should be increased; and the privatization of the navy commissaries should be abolished.

The effects of two levels (1.4 vs 2.8%) of fresh garlic on lipid oxidation and microbial growth in pork patties were evaluated. Hunter color (L, a, b), pH, thiobarbituric acid reactive substances (TBARS), oxidative volatile compounds, total bacteria and Enterobacteriaceae in the pork patties with or without fresh garlic were measured during storage at $4^{\circ}C$. Addition of fresh garlic decreased redness (a), while increased pH and yellowness (b) values of the fresh pork patties were observed, regardless of the levels added. The TBARS values of the pork patties were increased with the addition of fresh garlic (p<0.05). Similar results were observed in oxidative volatile compounds. A total of 13 volatile compounds were detected in the patties (5 sulfur-containing compounds, including allyl mercaptan, allyl methyl sulfide, diallyl sulfide, methyl-(E)-propenyl-disulfide, and diallyl disulfide, and the 8 other oxidative compounds, including 1-pentanol, hexanal, 1-hexanol, heptanal, (E)-2-heptenal, 1-octen-3-ol, (E)-2-octenal and nonanal). Fresh garlic accelerated development of oxidative products in the pork patties, especially hexanal and the total oxidative volatile compounds. However, the addition of 1.4 and 2.8% of fresh garlic inhibited the growth of total bacteria and Enterobacteriaceae, indicating low total bacterial counts and Enterobacteriaceae than the controls.
