In order to study the effect of modified atmosphere packaging(M.A.P.) and controlled atmosphere(C. A.) storage on keeping freshness of mushrooms (Agricus-bisporus). Mushrooms was packaged with polyethylene(P.E.) film (40, 60, 80) and C.A. conditions(CO2 concentration of 2%, O2 concentration of 2%) and storage at 01, RH(relative hummidity) 921%. Gas composition in film was changed rapidly at early of storage, but it kept a constant level after 14 days of storage, and then kept at the level of 6~9% CO2 and 2~5% O2. Weight loss was 5% in non-packed mushrooms after 3 days of storage, but P.E. film, CO2 treated, C.A. conditions were 5% after 21 days of storage. Flesh firmness of the mushrooms was continuously decreased throughout storage period and the lowest of flesh firmness changed was 80-P.E. film packing. Discoloration of the piteous of mushrooms appears to be the most Important factors to determine its marketability, L value of it appears to be of the high values at P.E. film packing and C.A. conditions during period. Large amount of ethanol and acetaldehyde were produced from the 7 days during storage, large contents of mannitol and trehalose were at the 14 days and 7 days during storage.

This study was conducted to determine the effects of storage conditions on apples treated with postharvest fungicides, benomyl and bitertanol. The fungicideds were applied to control Postharverst disease in apples during CA and cold storage. The stored Apple were tested monthly for weight loss, flesh firmness, titratable acidity, prix and free sugar. Relative to the control group, the pstharvest fungicide stoup had less disease. The fungicide treated apples stored in CA had a higher measured weight, better firmness and maintained acidity, prix and free sugar when compared to the control stoup monthly and after 200days. The fungicide treated apples in cold storage maintained their quality for 120days.

Potatoes, Irish cobbler, were subject to quality evaluation from the physiological and physicochemical points of view during storage under different temperatures and relative humidities for 11 months. Quality criteria were sprouting, rotting, weight changes, moisture, total sugar, reducing sugar and vitamin C. Low temperature condition(LT, 2∼4, 80% RH) was enough to preserve Potatoes for 11 months, but it was indicated to be limitations that the increase in reducig sugar as well as sprouting by about 3.3 to 6.7% occurred from the 3rd month of storage. Meanwhile, pit temperature(PT, 3∼15, 75∼85% RH), room temperature(RT, 7∼17, 80∼95% RH) and ambient temperature(AT, 2∼25, 62∼72 RH) were shown infeasible conditions for the storage of potatoes mainly due to the increase In sprouting-rate and subsequent quality-loss after 3 months of storage. Based on the results, it proposed that more economical conditions, ranging 10 to 15 and about 80% RH following sprout inhibition treatment should be used for the long-term storage of potatoes.

In order to determine the quality of Citrus unshiu(medium cultivar of satsuma mandarin) produced in Cheju, citrus fruits sampled at sorting places and harvested directly on citrus tree in south and north area of Cheju were analyzed. The fruits were grown in size till early of November, and soluble solids were increased continuously after that. Compared with the quality of citrus fruits as a factor of soluble solids, firmness, total sugar, pH, and color index, the optimum harvest periods were supposed to be reasonable from early of December for C. unshiu Marc. var. yonezawa and C. unshiu Marc. var. hayashi, Fruit weights and peel thickness had a linear correlation with increasing fruit size, but soluble solids and acid contents had not a correlation. The selection of C. unshiu variety was needed to determine by the properties of storage.

Physico-chemical components which are closely related to processed products were investigated on 10 varieties of Cheju citrus fruits. Juice ratio of Hungjin was the highest, 49.2%, while Sankyool was the lowest, 4.2%, which showed great differences among varieties. Peel ratio of Dangyooja was the highest, 46.1%, while both Navel orange and Hungjin were relatively low. Soluble solid(Brix) was relatively high In Sankyool, Meiwa Kumquat, Sambokam and Iyo. Acid content was the highest, 4.86% in sudachi and relatively high in Sankyool, Natsudaidai and Dangyooja. The Brix to acid content ratio was 13.9 in Meiwa Kumquat and more than 10 in Navel orange and Hungjin. Total sugar contents of Juice were 2.78∼10.94%, while reduced sugar contents were 1.63∼6.38% which showed higher in Meiwa Kumquat, Iyo and Navel Orange. Hesperidin and naringin, the sources of biiter taste and cloudness were low in Hungjin and Iyo. Soluble solid(Brix) of citrus juice showed highest statistical relationship(r=0.907) with total sugar, and was highly significant at 1% level.

Uncooked rice Tackju was prepared from the groud rice with different particle size such as 12, 20, 35 and 50 mesh, and its characteristics were analysed during the brewing. Reducing sugar and ethanol contents as well as yeast cell counts were the highest in main mash and Tackju prepared from 20 mesh fraction. Especially, reducing sugar content was about. 1.5-2.5 times as much as that obtained from 35 or 50 mesh fraction. The final concentration of ethanol in main mash prepared from 20 mesh fraction was 14.8%(v/v). It was about 1.5%(v/v) higher than the lowest one [13.35%(v/v)] which was prepared from 12 mesh fraction. No significant difference In total acidity was observed. Sensory evaluation revealed 20 or 35 mesh Tackju to be the best in overall preference, especially in sweet and refreshing tastes.

To study the shelf-life of cut cabbage kimchi, we examined the several quality characteristics of cabbage kimchi under various storage temperatures and packing materials. The pH of kimchi extracts were decreased to 4.0 in the condition of storage at 8 during 6 days, at 4 during 18days, 0 during 42 days. The increase patterns of the organic acid were reverse to the changes of pH under the all conditions. The contents of reducing sugar were continuously decreased at 8 , but increased gradually at 0 and 4 storage conditions. The contents of vitamine C were decreased at the early storage but increased to optimum ripening stage of pH 4.2-4.4 and after decreased continuously. The total bacterial cell counts of cabbage kimchi were increased suddenly at the early storage and after decreased gradually. And at the higher storage temperature, the more lactic acid bacteria were. On the results of sensory evaluation of cabbage kimchi at marketable shelf-life, sour taste and sour smell were significant under all experimental conditions by Duncan's multiple range test. On the above all results, we concluded that the marketable shelf-life of cut cabbage kimchi were 42 days, 19 days, 6 days at 0, 4, 8 storage condition respectively.

This study was performed to investigate the optimum moisture content and the best packaging method of dried persimmons for long term storage at room temperature. The package material to be used were 0.05mm polyethylene film, Wrap film, 0.08mm LDPE film exchanged nitrogen gas, and non package for untreated control. Before the storage, the initial moisture contents of dried persimmons were treated with 40%, 35% and 30%, respectively; 40% as traditional dryness, 35% as extending dry period one more week, and 30% as for two more weeks. The best package method was 0.08mm LDPE film exchanged nitrogen gas, and the optimum moisture control was 35%

Quality changes of Korean native-bee honey were investigated during processing and preseration at different temperature. There were no changes of HMF(Hydroxy methyl furfural) and proline contents, color and diastase activity in Korean native-bee honey, when the honey separated from honey combs at 20 and 40. However, at 50 and 80, browning of Korean native-bee honey was shown, HMF content was increased rapidly and proline content and diastase activity were decreased. There were no changes of chemical composition in Korean native-bee honey during storage at 4 for 6 months. But color was darken and HMF content was increased slowly in Korean native-bee honey during storage at 20. During storage at 30 and 40, HMF content was increased highly, proline content, diastase activity and total acidity was decreased rapidly. It is recommended that Korean native-bee honey is separated from honey comb and purified at less than 40 and stored at 4 through 20.
