This study was conducted to investigate the quality characteristics of soybean curd prepared with Opuntia ficus-indica fruit, freeze-dried Opuntia ficus-indica fruit powder, or heat-dried Opuntia ficus-indica fruit powder, without addition of a coagulant. The yield rates of the soybean curd were slightly decreased for the three curds containing Opuntia ficus-indica fruit; this was accompanied by a significant decrease in pH. Furthermore, the hardness and springiness of soybean curds coagulated with added freeze-dried Opuntia ficus-indica fruit powder or heat-dried Opuntia ficus-indica fruit powder were higher than the hardness and springiness of the coagulated controls. However, the cohesiveness and brittleness of two soybean curds were lower than for the controls, while the gumminess of the four soybean curds containing control fruit was the same. In terms of overall acceptability, the preferred soybean curd was the curd containing freeze-dried Opuntia ficus-indica fruit powder.

This study was carried out to investigate the quality characteristics and storage of noodle with added flowering cherry fruit powder. Wet noodles were prepared at concentration of 1, 2, and 3% (w/w) of the fruit based on flour weight. Moisture content of the noodles with or without flowering cherry fruit powder was 33.09~33.50%. Ca, K and Mg contents of flowering cherry fruit noodle were increasing at increasing concentrations of flowering cherry fruit powder. Cooked weight, volume, and water absorption decreased with increased fruit powder, whereas turbidity increased. For Hunter's color values of noodles, L (lightness) and b (yellowness) values decreased with increasing concentration of flowering cherry fruit powder, whereas a (redness) value increased. For mechanical characteristics of the noodles, adhesiveness of cooked noodle with flowering cherry fruit powder were higher than those of control. The pH of flowering cherry fruit noodle was lower than that of control during storage. Bacterial counts of wet noodle with flowering cherry fruit powders were lower than those of the control on the 10th day of storage at $5^{\circ}C$. From the sensory evaluation of 20's, texture, taste, and overall preference were not significantly different between the control and the fruit groups, but the color scores of 2% and 3% flowering cherry fruit noodle were significantly higher than that of 1% fruit noodle (p<0.05). In 40's sensory evaluation, color and overall preference scores of flowering cherry fruit noodle were significantly higher than those of control. In conclusion, the results of this study were suggested that the addition of flowering cherry fruit powder in combination with flour was tended to improve antimicrobial effects during storage when compared to control.

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 divided to three experiments for evaluating the effects of pre- or post-load 1-MCP on quality of 'Fuji' apples exposed to ethylene. The first experiment was compared for fruit quality at room temperature at 7, 14, 21, and 28 days between the control and 1-MCP-treated fruits followed storage of 130, 150, and 170 days. 1-MCP-treated fruits maintained higher fruit titratable acidity and firmness than those of control fruits. The second experiment was compared for fruit quality at room temperature at 7, 14, 21, and 28 days between fruits applied with pre-loaded-1-MCP on ethylene treatments (10 ${\mu}L/L$, 20 ${\mu}L/L$, and 40 ${\mu}L/L$) and control fruits. 1-MCP-treated fruits were not affected by ethylene concentrations, and had higher fruit weight and firmness than those of control. The third experiment was compared for fruit quality at room temperature at 7, 14, 21, and 28 days between fruits applied with pre-loading with ethylene (10 ${\mu}L/L$) followed by ventilation (8 h, or 32 h, or 56 h) and 1.0 ${\mu}L/L$ 1-MCP treatment. As observed above experiments, 1-MCP-treated fruits had higher fruit weight and firmness than those of control fruits, regardless of the delayed applications of 1-MCP.

BACKGROUND: Recently, the need for a method to cultivate 'Haryejosaeng' Satsuma mandarin has been increasing. However, there is limited information available as this is a new Satsuma mandarin cultivar, which was bred by the RDA in 2004. Many farmers who cultivate this cultivar follow the cultivation method similar to that used for 'Miyagawa' Satsuma mandarin, and suffer low production of optimum-sized fruits. METHODS AND RESULTS: This study was conducted to find out the optimum ratio of leaf-to-fruit for the stable production of high quality 'Haryejosaeng' Satsuma mandarin fruits in a non-heated plastic film house. Seven-year-old 'Haryejosaeng' Satsuma mandarin trees were used in the study. Before the treatment, the leaf-to-fruit ratio ranged from 5.7 to 17.9. The treatments included 10, 20, 30, and 40 leaves per fruit. The fruits were removed if over fruiting was observed at day 60 after full bloom. We investigated the fruit size and quality on the day of harvest. Flowering and fruiting patterns in each treatment were recorded for the following year. In the experiments, the flower-to-leaf ratio was 1.12 to 1.74. As the leaf-to-fruit ratio decreased, the fruit size and weight also decreased. Contrarily, the higher the ratio of leaf-to-fruit, the higher fruit size and weight were. It was noted that the ratio of 20:1 was ideal to produce the M grade optimum-sized Satsuma mandarin fruits on the day of harvest. However, higher ratio might result in fruits weighting above 100 g. There was no difference among the treatments in terms of fruit quality, such as total soluble solid contents, titratable acid, and color. In the subsequent years, flowering and fruiting in the treatments were lowered when the leaf number per fruit was 10, but they were improved when the leaf number per fruit was above 20. CONCLUSION: Based on the above results, the optimum ratio of leaf-to-fruit was found to be 20:1 for flowering and fruiting of 'Haryejosaeng' Satsuma mandarin. It is important that optimum ratio of leaf-to-fruit is set as a standard to produce good grade and quality of 'Haryejosaeng' Satsuma mandarin fruits.
