  • Recently, the incidence of cardiovascular diseases including high blood pressure and heart disease has increased with increased meat consumption in Korea. This study was performed to determine the optimal mixing ratio among ratios of 0, 1:0, 0:1, 1:1, 2:1, and 1:2 of mulberry leaf powder to mulberry fruit powder based on the anti-inflammatory effects. Then, the quality characteristics of the sauce for meat prepared with different mixing ratios (0, 1:1, 1:2, 1:3, 1:4, and 1:5) of mulberry leaf powder to mulberry fruit powder were assessed. The inhibitory effects of ML2MF1 (2:1 ratio of mulberry leaf powder to mulberry fruit powder) on NO and TNF-${\alpha}$ production were superior to those of other mixing ratios. With respect to color values of the sauce for meat prepared with different mixing ratio of mulberry leaf powder to mulberry fruit powder, as the mulberry fruit powder mixing ratios was increased, redness was increased but lightness and yellowness were decreased. The sensory evaluation of ML1MF5S (1:5 ratio of mulberry leaf powder to mulberry fruit powder) sauce for meat showed the highest score with respect to color, smell, taste, harmony with meat and the overall preference. In conclusion, as the mulberry leaf powder mixing ratio was increased, the anti-inflammatory activities were increased. But sensory evaluation scores were increased as the mulberry fruit powder mixing ratio was increased. Therefore, by performing further study, the method to increase mulberry leaf powder in the mixing ratio for improving the sensory evaluation should be provided.

  • This study was established to investigate the effects of Ca application on fruit mineral nutrients, quality, and browning of 'Fuyu' sweet persimmon (Diospyros kaki). Ca foliar application at 40ml/20L/tree had a greater fruit Ca concentration than did control, Ca fertigation (40ml/20L/tree), and Ca foliar application (40ml/20L/tree) coupled with IBA fertigation (40ml/20L/tree). Fruit mineral nutrient concentrations for Mg, B, and Mn were similar or lower in the foliar treatment compared to other treatments. Fruit color was not affected. Ca treatment, whether foliar applied or fertigated, was effective in maintaining fruit firmness and in decreasing the browning symptom in fruit after MA storage at $0^{\circ}C$ for 60 and 100 days. Although Ca foliar application + IBA fertigation treatment improved fruit firmness, the positive effect on the browning and decay occurrences in fruit was not shown.

  • The effects of developed grape bags on the micro-climate changes of bag, physiological disorder, pathogenic decay, quality and harvest time evaluation in 'Campbell Early' grapevines were studied. The temperature and light transmittance of developed grape bags showed no differences compared with the onces of conventional bag and non-bagging, but relative humidity and the amount of water evaporation were changed in all treatments. The occurrence of unfertilized fruit, poorly colored fruit, russet and gray mold rot showed no significant difference in all treatment at harvest time. Developed grape bags decreased effectively the occurrence of cracking fruit and bitter rot in 'Campbell Early' fruit. There was no difference in growth of cluster and berry, soluble solids and total acidity in fruits, degree of skin color and bloom appearance at harvest time. The skin color and fruit boom and harvest time evaluation in developed grape bags were resulted excellent compared with the once of conventional bag and non bagging.

  • The purpose of this study was to evaluate nutrition intake and diet quality according to beverage consumption status in elementary school students (ESS = 317), middle-school students (MSS = 431), and high-school students (HSS = 373). We analyzed data from the combined 2007-2008 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects were divided into two groups, the non-beverage group and the beverage intake group according to beverage intake from drink types (fruit-vegetable drinks, carbonated drinks, and dairy drinks). Intake of dairy drinks was significantly lower in the carbonated drinks intake (CDI) group, compared with the non-CDI group in the MSS group. Intake of vitamin C was significantly higher in the fruit-vegetable drinks intake (FVDI) group, compared with the non-FVDI group. Intake of Ca and P was significantly lower in the CDI group, compared with the non-CDI group. Intake of vitamin B2, Ca, and P was significantly higher in the dairy drinks intake (DDI) group, compared with the non-DDI group. The mean adequacy ratio (MAR) of the FVDI group and the DDI group was significantly higher than those of the non-FVDI and non-DDI group. In diet quality, nutrients less than 1 on the index of nutritional quality (INQ) were significantly higher in the CDI group, compared with the non-CDI group. In conclusion, consumption of carbonated drinks dropped the diet quality however, consumption of fruit-vegetable drinks and dairy drinks improved the diet quality of micronutrients. Therefore, a well-planned diet must be used for replacement of nutrients lost from excessive intake of carbonated beverages during a time in life when growth is especially prominent.

  • This study was carried out to determine the optimum nodes of pinching and fruit setting in muskmelon cultured by deep flow technique. A fruit was set either at 7~8th, 11~12th, or 15~16th nodes, and main shoot was pinched either at 22nd or 27th node. Distance between rows was set the same at 100cm, while the distance between plant in the row was set at 25, 35, 45, or 55cm. In treatments with the same node of fruit setting, fruit quality was enhanced and mean fruit weight increased on 22nd node compared to 27th node. terms of fruit quality as affected by node of fruit setting, larger fruits with lower soluble solid concentrations were produced as fruits were set at higher nodes. In terms of planting density, larger fruits with higher concentrations of soluble solid were produced in the 100cm$\times$45cm and 100cm$\times$55cm treatments compared to 100cm$\times$25cm or 100cm$\times$35cm treatment. Total fruit yields decreased as the planting density decreased. However, percent marketable fruits produced was the greatest in the 100cm$\times$45cm treatment, followed in descending order 100cm$\times$25cm, 100cm$\times$35cm, and 100cm$\times$55cm treatments.

  • This work was carried out to evaluate the effect of preharvest sprayable 1-methylcyclopropene (1-MCP: $Harvista^{TM}$) treatment on the fruit quality attributes in cold stored 'Gamhong' (Malus domestica Borkh) apples. Preharvest sprayable 1-MCP treatment did not affect fruit qualities at harvest but titratable acidity (TA) was higher in fruit treated 10 days before harvest (DBH) than in control. During cold storage, fruit firmness and TA were higher in 1-MCP treated fruit than in control fruit as storage duration progressed, while SSC was not affected. Internal ethylene concentration (IEC) levels were not different among treatments at harvest. While the IEC level in control fruit reached to $58.3{\mu}L{\cdot}L^{-1}$ after 6 month cold storage, the IEC levels in 1-MCP treated fruit ranged from 18.2 to $25.0{\mu}L{\cdot}L^{-1}$. Therefore, this result indicates that preharvest sprayable 1-MCP treatment should be another promising approach to retain fruit quality attributes in long-term cold stored 'Gamhong' apples.

  • 'Niitaka' (Pyrus pyriforia) has been the major cultivar of the Asian pear since the 1970s, and yielded about 70% of pear production in South Korea in 2002. When Chuseok (Korean Thanksgiving Day) is earlier than the fruit maturation period, farmers seek to advance the harvesting date to keep pace with the increase in consumer demand caused by the holiday. However, unripened fruit is of suboptimal marketable value because the flesh has a low soluble solid content, the fruit color is not attractive, and stone volume is high. Compost treatment can enhance soil microbial activity and affect soil chemistry, which may accelerate fruit maturation and allow an earlier harvesting date. Therefore, we examined the effect of 2 years of compost application on the fruit quality of Asian pear trees grown under conventional management conditions. The Hunter "L" and "a" values were higher in compost-treated fruit, which also showed greater sweetness and lower acidity than did conventional fruit. The stone volume was reduced and fruit calcium concentration was increased by compost treatment. Therefore, compost treatment may advance fruit harvesting owing to the increased marketability afforded by attractive skin color, sweetness, and reduced stone volume.

  • Schisandra chinensis is a fruit which is called Omija in South Korea. The Korean word Omija means "five flavors" (sweet, spicy, sour, bitter, and salty). The aim of his study was to investigate the correlation between growth characteristics and lignans (gomisin A, gomisin N, schisandrin) contents of Schisandra chinensis. The method for determining lignans was validated by measuring the linearity, limit of detection (LOD), limit of quantification (LOQ), precision and accuracy using UPLC-UV. Growth characteristics of S. chinensis such as number of fruits per fruit bunch, length of fruit bunch, width of fruit bunch, fresh weight of fruit bunch, length of fruit, width of fruit, fresh weight of fruit, fresh weight of 30 fruits, and sugar contents of fruit were measured. From the results of correlation analysis, it was found that the contents of lignans showed a significantly negative correlation with fresh weight and sugar contents of fruit. These results will be used to study for quality control of S. chinensis fruit.

  • In response to the continuous changes in current consumer demands and market trends for postharvest produces, the functional application for agricultural packaging is becoming increasely significant. This paper focuses on the overview of important changes in physical and chemical status related to postharvest physiology and applications of the functional packaging materials for maintaining the freshness of fruits after harvest. During postharvest treatment and storage periods, fresh fruits undergoes the ripening process in quality attributes of the fruit such as major changes of texture, color, and flavor. Major fruit packaging technologies are concerned with correct gas permeable film and functions of ethylene removal, antimicrobial, and antifogging substances to keep the effective freshness. Application guidelines for the functional packaging in fresh produces were studied.
