  • 금년은 근래에 보기 드문 각종 농작물의 대풍의 해이다. 과실류의 작황 역시 풍작을 알리고 있다. 거기에다 농가소득증대 사업으로 특용작물의 재배가 권장됨에 따라 과실류생산은 해마다 증가되어 왔으나 가공처리는 이를 뒤따르지 못해 생산물의 대부분이 생식용으로 소비되어온 실정이다. 풍작으로 다량생산된 과실류의 안전 저장과 적기출하를 위한 각종 저장법을 사과$\cdot$$\cdot$감귤류를 중심으로 알아보기로 한다.

  • 과실류 식품에 포함된 엽산치를 Lactobacillus casei 미생물을 사용하여 분석하였다. 측정시 결합형으로 존재하는 엽산을 유리형으로 하기 위해서 conjugase효소를 사용했고, 산화되기 쉬운 형해로 된 엽산을 보호하기 위하여 비타민 C를 첨가하였다. 과실류는 일반적으로 엽산을 소량 함유한 식품으로 나타났다. 각 과실에 포함된 엽산 분석치는 사과 7.5, 살구 8.6, 바나나 20.2, 앵두 3.0, 포도 11.2, 귤 26.6, 복숭아 3.5, 배 10.5, 자두(붉은색) 3.7, 자두(노란색) 2.0, 딸기 19.7, 수학 3.8, 감 7.5, 참외 3.7, 토마도 $9.1{\mu}g$으로 각기 식품 100g 중에 함유 되었음을 보였다.

  • Bactrocera depressa and B. scutellata are serious insect pests to pumpkin in Korea. Adult stage which exposes to aerial condition is the optimal target for control because the immature stages of both species hide within host fruit, flowers or under ground. This study aimed to develop an attract-to-kill technique of their females. A commercially available attract-to-kill agent was not effective to attract these two pumpkin fruit flies. This study developed an attractant containing protein-based terpinyl acetate (TA). This TA-protein lure was effective to attract two pumpkin fruit flies. It attracted both sexes with female-biased frequency (60-70%). This TA-protein lure would be used for control both pumpkin fruit flies and may be used for monitoring field populations of B. depressa, in which specific attractant is not known.

  • Increase in world trade commodities along with climate change entails frequent pest insect invasions from subtropical to temperate zones. Tephritidae is one of two families in fruit flies along with Drosophilidae and consists of more than 5,000 species. Some tephritid flies in genera Anastrepha, Rhagoletis, Ceratitis, and Bactrocera are highly invasive and give serious economic damages on fruits and vegetables in temperate zones. This review focuses mainly on Bactrocera fruit flies, which have been well studied in control techniques to defend their invasion and colonization. Though various control techniques against Bactrocera fruit flies have been developed, less efforts have been paid to establish efficient integrated pest management (IPM) programs. This review introduces current control techniques of fruit flies and some successful IPM programs implemented in subtropical islands. In addition, major fruit flies infesting crops in Korea have been also reviewed in their occurrence and control programs.

  • This study investigated the Antimicrobial activity of Rutaceae fruit ethanol extracts against microorganisms-induced skin inflammation in cosmetic materials. Rutaceae fruits were separated in two parts of whole fruit (pulp, pulp fegment membrane, peel) and peel, and extracted with 70% ehtanol. The results demonstrated that Rutaceae fruit ethanol extracts showed antimicrobial activity in 5 strains except Staphylococcus aureus. In particular, the antimicrobial activity against Staphylococcus epidermidis was the best in fresh lemons whole fruit. The antimicrobial activity against Escherichia coli was shown only in fresh lemon peel and fresh trifoliate peel. Additionally, antimicrobial activity against Propionibacterium acnes was shown only in the dried lemon peel. In the results of antimicrobial activity against Pityrosporum ovale, in the case of fresh fruits, citron whole fruits showed the highest effect, followed by lemon whole fruits and mandarin orange peel. And in the case of dried fruits, orange peel showed the highest effect, followed by trifoliate peel, mandarin orange peel and lemon peel. Therefore, it is considered that lemon, which shows antimicrobial activity against all skin inflammation-causing microorganisms, can be used as a natural material for improving skin inflammation in cosmetics.

  • 최근 일본은 남서부지방의 과실류 등에 기생하는 것이 확인된 과실파리에 대한 방제법으로 방사선을 이용한 ${\ulcorner}$불임충방사법${\lrcorner}$의 실시를 검토중이라고 한다. 이 방법은 Co-60에 의한 감마선으로 불임화한 숫놈의 성충을 풀어 야생의 암컷과 교미시킴으로서 방제하는 것인데, 우리나라도 소나무의 솔잎혹파리근절이 산림정책의 중요한 과제의 하나인 바, 관심거리가 아닐 수 없다.

  • A rapid and very sensitive high-performance liquid chromatography/atmospheric-pressure chemical-ionization mass spectrometry method to detect ethylenethiourea (ETU) fungicide residues in fruits was developed. Methylene chloride was used as the surface extraction solvent for the target component. Recovery rates improved when cysteine hydrochloride and sodium carbonate were added to product prior to fortification. The limits of detection and quantification were approximately 0.006 and 0.02 mg/kg, respectively, from mandarin oranges. Recoveries from mandarin oranges, oranges, bananas, and pears, spiked in the range of 0.05-0.5 mg/kg, averaged 80-100%. The proposed method was used to monitor the presence of ETU in commercial fruits purchased from different markets in Seoul, Korea. ETU was found in four orange peels and in three mandarin orange peel samples. The highest ETU residue levels were $73.6{\mu}g/kg$ and $29.8{\mu}g/kg$.
