Regarding the country’s pears for processing, high purchase costs and the instability of supplies are pointed out as the largest difficulties in the operations of pear processing companies. The ratio of domestic pears supplied as raw ingredients to the food producing in gredients was about 6.9% in 2008, indicating a predominant level of reliance on imports for raw materials in the fruit beverage industry. If the prices of the original fruits of raw materials are high, fruit processing businesses should process their products by importing cheap ingredients from foreign countries. Therefore, the measures to reduce raw material costs through the reduction in pear cultivation and production costs and operating expenses are required. Accordingly, this study identified the methods to replace the work of bagging (coating) for the purpose of reducing production costs and the pear thinning limits by cultivars to reduce the use of agricultural chemicals for processed pears, and reviewed the values and practicality of those measures.
In order to find out the effects of the application of TiO2 and Kaolin on replacing the task of bagging ,the diluted solutions of 0.5% TiO2, 1.0%TiO2, 2.0% TiO2, 10% Kaolin, and 20% Kaolin were processed. When the weight changes of the pears according to the growth phases of 90days after the full bloom and after the foliar spray were examined, the ‘Hosui’ cultivar showed similar weights to the conventionally controlled pears. The pears treated with the foliar spray of 1.0% TiO2 and 10% Kaolin were revealed to be marginally influenced by heavy fruiting. When the content by each pear was examined, the sugar content of the pears after the foliar spray of TiO2 and Kaolin did not show consistent patterns by processing methods and cultivars. In terms of fruit pressure, among the pears processed with the foliar spray of 1.0% TiO2, the ‘Hwangkeumbae’ and ‘Kamcheonbae’ cultivars were shown to have substantial pressure enhancement effects. As for skin coloration, based on the skin color of non-bagging pears, the pears processed with 0.5, 1.0% TiO2, and 10% Kaolin were confirmed to have acceptable levels of coloration. Interms of the curbing effects on the occurrence of pearscab, the processing with 0.5, 1.0% TiO2 and 10% Kaolin was relatively effective. The content of polyphenol compounds was revealed to be markedly high in the pears processed with 1.0% TiO2 and 10% Kaolin as compared to the conventionally controlled pears.
To identify the effects of rain-shelter with net cultivation aimed at reducing the use of agricultural pesticides, the test pears were segmented into a group processed with rain-shelter with net, a group processed with mating disrupters, and a group with
conventional control. Excluding the rain-shelter with net cultivation pears, the pears processed with mating disrupters and conventional control were categorized into the test pears that were subject to the spray of pesticides. When compared with the
conventionally cultivated pears, the rain-shelter with net pears showed the low incidences of pear rust, scab, and black spot. As for mites, the conventionally cultivated pears showed a two times higher incidence. The occurrences of Carposinasasakii, Archippusbreviplicanus, and Adoxophyes spp. were rarely found in the rain-shelter with net cultivation pears.
In order to identify the limits of pear thinning by cultivars for the quality maintenance of the pears for processing purposes, the levels of thinning were segmented into light (two pears per each small cluster), medium (one pear per each small cluster), and heavy (one pear per each small cluster after removing one small cluster between small clusters). According to the comparison on the sizes and qualities of the selected pears, the ‘Kamcheonbae’ and ‘Hosui’ cultivars showed similar total
outputs according to thinning levels. In terms of the comparison of fruit sizes, the ‘Hwangkeumbae’, ‘Kamcheonbae’, and ‘Hosui’ pears exhibited similar levels. In terms of sugar content, the ‘Hwangkeumbae’ and ‘Hosui’ pears showed a low difference. The Scab occurrence by different fruit loads at harvest time in pear cultivars, the ‘Kamcheonbae’ and ‘Hwangkeumbae’ were indicated a higher resistence against the scab disease. The damage occurrence by insects at the different fruit loads in pear cultivars, the ‘Kamcheonbae’ and ‘Hosui’ had demonstrated the most low level of damage.
In order to find out suitable cultivars according to individual processing purposes, juices, dried fruits, fresh cut pears, wines, and vinegars were manufactured, and then the quality characteristics by pear cultivars were examined. Among the pear juices, Wonhwang, Gamcheon, and Hosui pears showed the best color formation and juice yields. As for the dried pears, Hwanggeum and Mansoo cultivars had superior coloration and textures. In the fresh-cut pears, the browning of Gamcheon and Niitaka pears were delayed. When the freshness of the cut pears was taken into account, storages at 0℃ were most suitable. As for the pear wines, 11 to 12% alcohol was produced in all cultivars on the 15th day of fermentation, which was a similar level to the alcohol content of commercial wines. In addition, the total phenolic compound content of the pear wines by cultivars was exhibited in order of Gamcheon> Hwanggeum> Hosui> Niitaka> Chuhwang. In color formation, the Niitaka, Chuhwang, and Hwanggeum wines showed yellow colors. According the results of a TLC analysis on the pear wines, compared to the beginning of fermentation, the wines on the 60th day of fermentation showed the pattern of an increase in antioxidant activity. Among the pear vinegars, the total acidity and total phenolic compound content of those made from the Chuhwang and Gamcheon pears were most superior.
Accordingly, the results of this study on substitution methods for bagging, using of rain shelter with net for application of agro-chemicals reduction, and the different fruit loads at the harvest time for examination into the most optimal condition of processing pear cultivars quality should be recognized as very useful important methods for cultivative coast reduction in the aspect of scientific and practical application.
