  • Among the 6500 accessions of the pepper germplasm which conserved at RDA Genebank, 319 accessions were investigated charateristics such as their growth habit, flowering and fruit shape in Capsicum frutescens. All accessions were characterized for their 14 qualitative and 16 quantitative characters. Results revealed that both qualitative and quantitative characters exhibited wide variation among the studied germplasm. The hypocotyl color, which investigated in juvenile stage, was divided in three types such as green, purple, and purple with green, and most of the accessions showed in purple. Flowering starts from 7 May, and most accessions were starting to flower from 27 May to 25 June. The fresh color of the mature pepper were red, yellow, orange, Etc. Fruit shape were mostly elongated, while exhibited ball shape and round shape were a few. The fresh weight of fruits ranged from 0.2 to 42.3, and the diameter of fruit showed from 4.2 to 45.1 mm, respectively. The phenotypic diversity exists in Capsicum frutescens. provide valuable information to improve agronomic traits in pepper breeding program.

  • 기능성 소재로서의 버찌 분말의 이용가능성을 알아보기 위해 버찌 분말을 0, 1, 3 및 5% 첨가한 식빵을 제조하여 품질 특성을 조사하였다. 반죽 및 식빵의 pH는 버찌분말 첨가에 의해 감소하였으나, 무게는 증가하였다. 식빵의 부피, 비용적, 굽기 손실률은 버찌분말 첨가에 의해 유의적으로 감소하였다. 발효팽창력 또한 버찌분말의 첨가량이 증가할수록 유의적으로 감소하는 경향을 보였다. 식빵의 색도 측정 결과는 L(lightness)값과 b(yellowness)값에서 crust와 crumb 모두 버찌 분말 첨가량이 증가할수록 유의적으로 감소하였고, a(redness)값은 crust, crumb 모두 버찌 분말을 첨가할수록 유의적으로 증가하였다. 버찌 분말 첨가 식빵의 견고성, 씹힘성은 버찌 분말의 첨가량이 증가할수록 유의적으로 증가하는 것으로 나타났고, 응집성은 감소하는 것으로 나타났다. 탄력성은 유의적 차이를 보이지 않았다. 항산화 활성은 버찌분말 첨가량이 증가함에 따라 항산화 활성이 증가하였다. 식빵의 관능검사 결과 버찌 분말 첨가는 색, 냄새, 맛, 질감 및 전체적인 기호도를 향상시키는 긍정적인 영향을 미치나 5% 이상의 너무 많은 버찌 분말 첨가는 관능적인 기호도를 오히려 떨어뜨리는 것으로 나타났으며, 버찌 분말 3% 첨가군의 선호도가 가장 좋아 식빵의 품질 및 관능 특성, 기능성을 고려한 버찌 분말 첨가량은 3% 첨가군이 최적 조건일 것으로 판단된다.

  • 본 연구는 1988년 식품개발연구원 지방명품 산학연 협동연구사업 연구비 지원에 의해 수행되었음. ^x The possibility of winemaking from a new wild grape(NWG) cultivated in north Kyungki province in Korea, was tested by analyzing the proximate and physicochemical components of fresh fruit, the chemical components and sensory evaluation of wines made from the grape. NWG contained about 10% seed, and about 70% of juice. Total sugar content, total acidity and pH of the fruit juice were 17.50, 1.14 and 3.48%, respectively. Tartaric acid and malic acid contents of the NWG juice were 0.396 and 0.509%, respectively. Ethanol fermentation of the NWG by Saccharomyces cerevisiae Montrachet was rapid. The ethanol content, total acidity and pH of pink wine made from the NWG juice showed 11.88, 0.85 and 3.55%, respectively. Tartaric acid and malic acid contents of pink wine were 0.208 and 0.421%, respectively. Total anthocyanin content(A520) and color intensity(A520+A420) of pink wine were 5.46 and 9.39, showing greatly higher total anthocyanin content and color intensity than those of European red wines. Total phenol contents of NWG wine were 2,300∼3,800mg/ℓ. The pink wine made from the fruit juice was better than the red wine in their quality parameters and sensory scores.

  • In the present study, we investigated the effects of artificial removal of corolla and calyx lobes from open flowers on fruit development and fruit quality of strawberry (Fragaria ${\times}$ ananassa Duch.). Removing the corolla had no significant effect on fruit weight, hardness, length, and diameter, Hunter L, a, b values, sugar content and acidity. However, removing the calyx lobes significantly inhibited longitudinal and transverse growth of the fruits, resulting in diminished fruit size. In addition, merchantable fruit quality significantly decreased upon removing the calyx lobes, and this tendency was increased as more calyx lobes were removed. Nonetheless, removal of the calyx lobes had no effects on fruit color, sugar content, or acidity, similar to the effect of corolla removal.

  • This study was carried out to get the information of Plum tree (192 germplasm) collected in Korea, and to evaluate the organic acid contents and fermentation solution. The organic acid content of fruit was 50.9 ± 6.0 mg/g, and which was composed of 55.5% of citric acid, 43.4% of malic acid and 1.1% of oxalic acid, and showed large difference among germplasms. Oxalic acid and malic acid made no differences in organic acid content according to flesh color, whereas citric acid and total organic acid contents were highest in orange color and lowest in whitish green. Malic acid, citric acid and total organic acid contents did not show differences among fruit weight groups, but oxalic acid content was highest at fruit weight of 5.1 ~ 10.0 g and lowest at more than 20.1 g. The sugar content of fermentation solution of fruit was 55.7 ± 1.6 °Brix and the harvest rate was 116.7 ± 8.7%. The correlation coefficients among fruit weight, the sugar content (°Brix) and harvest rate of fermentation solution were very low, and there were correlations of r=-0.551⁎⁎ between fruit weight and oxalic acid, r=-0.767⁎⁎ between malic acid and citric acid, and r=0.834⁎⁎ between citric acid and total organic acid content.

  • Melon fruits are a year-old plant in the family Cucurbitae and are the most cultivated fruit in tropical countries. Melon flesh is an important source of anti-cancer, antioxidant effects, attracting attention as a functional food. We investigated the morphological properties, β-carotene content, and cucumisin activity of seeds of 58 melon genetic resources. Melon resources have shown various morphological properties. Melons grouped by morphological properties were the five groups. β-carotene content varied between 82.34 mg/kg, 86.75 mg/kg, 25.56 mg/kg, 86.25 mg/kg, and 54.65 mg/kg. Between β-carotene, cucumisin activity and other quantitative fruit morphological properties, the color of the pulp and the firmness of the pulp had a significant amount of correlation between the β-carotene content. However, cucumisin activity and β-carotene content had significant negative correlation, and the color of the fruit and shape of the fruit had significant negative correlation with β-carotene content and activity of cucumisin. Our study vindicated that high diversity in melon morphological characters of genetic sources that provide beneficial baseline data for the future and in the activity of β-carotene and cucumisin, and these results could predict indicators of β-carotene content by the length of leaf, the width of fruit, the length of joint, and the length of seed, and collectively the morphological properties of melons could help predict indicators of β-carotene content and help develop functional sarcoma and farmhouse cultivation.

  • Fruit bagging paper is used for protecting of fruits from insect and/or microorganisms. Generally, fruit bagging paper controled light, temperature and humidity and then it is used for good fruit color, size and taste. The physical properties of conventional(domestic and abroad) fruiting bag and wrapping paper were analyzed and compared to each other. And also, the optical properties of conventional(domestic and abroad) fruiting bag and wrapping paper were analyzed and compared to each other. The chemical additives and residual herbicide in conventional fruiting bag and wrapping paper were analyzed and compared to each other. The analyzed data was bench marked for developing water repelling paper and embossing paper.
