여름철 강원도 고랭지 재배되는 착색단고추는 비상품과로 분류되는 생리장해과가 발생이 많은데, 본 실험은 이들 생리장해과의 신선편이 이용 가능성을 알아보고자 실시하였다. 착색단고추의 정상과와 배꼽썩음과 그리고 납작과를 수확하여 신선편이로 제조하여 수확 후 생리현상과 몇 가지 MAP 조건에서 저장성을 비교하였다. 저장전 이들 신선편이의 호흡률과 에틸렌 발생 률은 정상과와 생리장해과의 차이에 일정한 경향이 었으며 통계적 유의성도 나타나지 않았다. 이들 3가지의 형태의 과실의 신선편이를 두께 $25{\mu}m$와 $50{\mu}m$의 세라믹 필름으로 포장하여 $4^{\circ}C$와 $9^{\circ}C$ 그리고 상온에서 저장하였다. 저장중 생체중 감소는 모두 1.1% 이하로 과실형태로는 그 차이에 유의성이 없었으며 필름 두께가 얇을수록 저장 온도가 높을수록 컸다. 이들 포장재내 이산화탄소와 산소농도의 경우 품종과 과실형태별 차이에 유의성은 없었으며 저장온도별로 저온이었던 $4^{\circ}C$ 처리와 필름종류에서는 두께가 얇았던 $25{\mu}m$ 세라믹 필름포장처리에서 낮은 이산화탄소와 높은 산소 농도를 보였다. 저장기간 중 변화를 보면 $4^{\circ}C$ 저장은 9일 이후, $9^{\circ}C$ 저장은 6일 이후 포장재내 급격한 이산화탄소 농도 증가와 이와 동반된 산소 농도 감소나 나타났는데, 이 시점은 외관상 품질이 급격히 감소한 때와 일치하였다. 에틸렌 농도는 상온을 제 외한 모든 처리구에서 $7{\mu}L{\cdot}L^{-1}$ 이하를 보였는데 포장재 두께가 얇은 $25{\mu}m$ 세라믹 필름포장과 $4^{\circ}C$ 저장 처리구에서 낮게 유지되었으며 과실형태별로 유의성 있는 차이나 일정한 경향은 없었다. 저장 최종일에 외관상 품질은 3일간 저장하였던 상온에서 가장 크게 감소하였으며 처리간 차이에 유의성은 없었다, $9^{\circ}C$와 $4^{\circ}C$ 저장에서는 정상과에서 외관상 품질이 높게 유지되었으나 생리장해과와의 차이에 통계적 유의성은 없었다. 저장온도별로 9일간 저장한 $9^{\circ}C$에 비해 12일간 저장한 $4^{\circ}C$에서 높게 유지되었다. 이상의 결과를 종합하면, 착색단고추 과실의 형태 및 품질이 신선편이의 저장성에 큰 영향을 주지 않았으며 저온 장해가 있는 착색단고추 과실이지만 신선편이의 경우 $4^{\circ}C$의 저온이 보다 효과적인 것을 알 수 있었다.

Southeast Asia, a typical tropical region, plays an important role in exporting a variety of fruits worldwide. The market for fresh fruits has been growing consistently, and this is a chance for Southeast Asian countries to increase their national income. However, export of tropical fruits has limitations such as a short shelf life and difficulty in maintaining the quality because of tropical climate conditions and undeveloped postharvest technologies in Southeast Asia. An important objective for developing postharvest technologies is to extend the shelf life of fresh fruits without deterioration in fruit quality. Therefore, it is essential to determine factors that affect the shelf life of fruits. The shelf life of tropical fruits is significantly dependent on the inherent properties of the fruits, extrinsic conditions, postharvest treatment, and microbial contamination. Recently, Southeast Asian countries have supported agricultural research groups for developing new postharvest technologies and minimizing postharvest losses and maintaining export fruit quality so that the total sales of tropical fruit farms can increase. This review introduces how the primary factors for extending the shelf life of tropical fruits can be determined and discusses the development of postharvest technologies for tropical fruits in Southeast Asian countries.

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.

A survey on Korean families′purchase of fresh fruits and vegetables was conducted to increase understanding of families′food decision making. Two hundred ninety seven families with at least one elementary-school age child were selected from four elementary schools to complete a questionnaire during April, 2001 in Gyeongju, Korea. Descriptive statistics, Chi-square test, T-test, and ANOVA statistics were used to analyze the data. The major findings are as follows: Families bought fresh fruits and vegetables at the public markets or the farmer′s markets and a large supermarket most frequently in both summer and winter. Families grew produce by themselves and bought them from farmers directly least frequently in both summer and winter. Families whose housewives had less than middle school education brought fruits and vegetables from Agricultural Co-ops and grew thens by themselves more frequently compared to those who had higher education. On the other hand, families whose housewives had graduated from 4 year college bought fruits and vegetables from large supermarkets more frequently compared to those who had lesser education. "Quality"and "safety production"of fruits and vegetables and "clean environment of store"were the three most important factors when they decided the place to buy fruits and vegetables. "Being treated as a valuable customer" and "ease of finding things"were the two least important factors. Families whose housewives were in their thirties valued "cleanness of the store"and "being treated as a valuable customer"important factors when they decided the place. Families whose housewives had less than middle school education thought that price, availability of public transportation, and availability of locally grown food were the important factors for deciding the place compared to those who had higher education. The price was the factor which low-income families thought important for decision making on the place to buy fruits and vegetables.

Moisture loss of fresh fruits and vegetables is a main cause of deterioration. It resulted not only in the direct quantitative loss, but also in change in appearance, texture and nutrition. To reduce the loss of moisture content during the distribution in the market, fresh products are packaged using plastic films. But, most of the fresh products are packaged manually in Korea. In order to minimize the labor requirement, the packaging machine for fruits and vegetables was developed and tested. Prototype was composed of film feeding unit, bag former, products feeding conveyor, film feeding roller, center sealer, end sealer and discharge conveyor. Green peppers, carrots and perilla leaves were tested with prototype. Prototype could pack 1780, 1390, 1780 bags per hour at the feeding speed of 0.08m/s respectively and 2250, 1810, 2640bags per hour at the feeding speed of 0.10m/s respectively. And packaging speed of green peppers and carrots was improved by 3.7 and 3.4 times compared with manual packaging. The packaging condition with the prototype was good and the products had almost no damages.

The anthelmintic substance of the roasted fruits of Prunas mume against Clonorchis sinensis was isolated and its structure was identified by chemical and physical methods. The results obtained from the experiments are as follows: 1) The methanol extract of the roasted fruits of P. mume was fractionated into four parts: petroleum ether, ethyl ether, ethyl acetate and water soluble part. Among these, etherial fraction was found to have strong wormicidal effect on liberated metacercaria of Clonorchis sinensis. 2) From the etherial fraction, the wormicidal substance was isolated by silica gel, polyamide and sephadex column chromatography and identified to be 5-hydroxymethylfurfural (5-HMF) by chemical and spectral data. 3) 5-HMF was synthesized and administered to the rabbits infected with C. sinensis. On the 2nd day after administration, the EPG (eggs per gram in feces) reached to the maximal value. Among the adult worms isolated from the bile duct of the treated animal, 84% of worms were damaged morphologically. 4) The content of 5-HMF in the fruits of P. mume which were roasted in an oven at $90-110^{\circ}C$ for 52 hours and that in the fresh fruits was evaluated by HPLC. The content of 5-HMF was 0.8% in the roasted fruits and 0.02% in the fresh ones.

The effects of modified atmosphere(MA) storage for fresh red chili pepper and red bell pepper fruits were investigated with storing in polyethylene film with various fine holes. During the storage of the both pepper fruits, the weight loss, color change, mold emergence, and firmness were evaluated. The weight loss of pepper fruits packaged without holes on film was less than 3%, even though it was each 50% and 25% for non packaged red chili pepper and red bell pepper fruits. The rates of mold emergence of red chili pepper and red bell pepper fruits were reached to each 60% and 50% at the end of storage period as stored in film without holes. However, the rate of mold emergence of pepper fruits was lowered when fruits were stored in MA with low relative humidity (70∼80%). The color and firmness of pepper fruits were not much changed when fruits were stored in MA with high humidity.
