Park, Seok-Hee ; Roh Young-Kyun ; Cho, Doo-Hyun ; Choo, Yeun-Dae ;
Korean Journal of Food Preservation, volume 7, issue 3, 2000, Pages 241~244
Grapes(Vitis labruscana B) were fumigated with acetic acid at 20mg/liter to reduce storage decay and packaged with polyethylene film(0.03mm), then stored for 90 days at 2
. Modified atmosphere packaging reduced slightly weight loss and soluble solids content during storage. Acetic acid fumigation decreased effectively berry shattering and achieved remarkable control of rotting for storage. Two grape cultivars, 'Campbell Early' and 'Sheridan', fumigated with acetic acid had only 0.7~2.9 berries rot compared with 8.3~27.6 berries rot of cluster for grapes that were not fumigated.

It was attempted to find a method to prevent greening of crushed garlic. The storage conditions and heat treatments before crushing were tested for the prevention of greening in crushed garlic. 'Namhae' garlic (sub-tropical type), 'Seosan' and 'Danyang' garlic (traditional) type for cool area) were stored in room temperature(20
, low temperature(0
), and CA(O
5%) storage for five months, and their samples were crushed. The crushed garlic had no significant differences in greening according to the cultivars. Greening did not occur for the crushed garlic from bulbs stored either in room temperature or CA storage. Greening was the unique symptom observed in crushed garlic from bulbs stored in low temperature. For the prevention of greening, heat treatment was conducted at 40, 35 and 30
prior to make the crushed garlic from bulbs which were stored in low temperature. The effective duration of heat treatment before crushing was 7 days at 30
, 3 days at 35
, and 1 days at 40
Greening was most effectively prevented in 1 day at 40
treatment. During the heat treatments, changes in enzymatic pyruvic acid content and sprouting rate were slightly observed in garlic bulbs treated at 40
for 1 day.

Soybean curd has been known as one of the most favorite traditional Korean foods as well as being high in protein. Each concentration of added natural materials soybean curds was chosen as 4% of carrot, 10% of cucumber, 1.0% of spinach and 0.05% of green tea powder. The yield of soybean curd containing natural materials was similar to that of non-containing curd. According to add GDL as coagulant, the yield of soybean curd containing natural materials was the highest. The turbidity of added natural material soybean curds was the highest coagulated with
, but soybean curd containing green tea had the highest turbidity in the coagulated with GDL. In the chromaticity and texture properties of the additive natural materials in yhe soybean curd, the variety of additives had no effect. In the composition of natural materials, the carotenoid and chlorophyll content of soybean curds were high with
but polyphenol was high use of

Korean Journal of Food Preservation, volume 7, issue 3, 2000, Pages 256~261
Carrot, cucumber, spinach which contain carotenoid and chlorophyll pigment, and green tea which contain catechin were selected to natural materials. Although the yield of soybean curd with added natural materials were below than non-added soybean curd. Also, the additive natural materials in the soybean curd had no effect to the texture in soybean curd. The optimum concentration of added natural materials were high acceptability opposed to the non-containing soybean curd. The optimum concentration of added natural materials soybean curds was obtained : 4% of carrot, 10% of cucumber, 1.0% of spinach and 0.05% of green tea powder. And soybean curd with spinach and green tea addition had a longer shelf life because it prevented growing of bacteria in the early stage. Therefore, it could be possible to prevent the deterioration of soybean curd with added natural materials.

The rhizomes of Polygonatum odoratum(Dunggulle in korean name) have been used as a traditional medicine for a tonic, remedy of fevers of influenza, cough and lung trouble. In this experiment, water extract of Dunggulle was added in brewing korean traditional rice wine. Fermentation characteristics such as content of total acid, pH, temperature, total sugar and alcohol concentration were investigated during fermentation periods. Changes of fermentation characteristics were remarkable in the initial period(0~3 days), slow in the middle(4~6 days), and almost unchangeable in the final(7~10 days). Total acid content was remarkably increased during the initial period but slowly decreased afterward. As the content of Dunggulle extract is increased, total sugar content was slightly increased. At the first day of fermentation, total sugar content was 19.6% in control, 22.6, 23.3 and 25.6% in Dunggulle extract 2.5, 5.0 and 7.5% added group, respectively. In the initial period, content of alcohol in control was highest than in Dunggulle extract added group. The content of alcohol in 4 kinds of wine showed highest value at the sixth day and those of control and Dunggulle extract 2.5% were 16.0, 16.1%, respectively. Sensory evaluation in taste was not significantly different among control and Dunggulle extract added group.

Lee, Jung-Eun ; Lee, Eun-Young ; Kwon, Joong-Ho ; kim, Hyun-Ku ;
Korean Journal of Food Preservation, volume 7, issue 3, 2000, Pages 273~277
Some fundamental conditions were investigated in microwave-assited extraction (MAE) for oleoresin from Chinese dried ginger. The fifty watts of microwave energy(2,450 MHz), 60 mesh in particle size and 1:10 (g/mL) ratio of sample to solvent were the optimum conditions. Lower yield of soluble oleoresins was obtained at higher concentrations of ethanol. Radical scavenging ability was highest in extracts by using 25% of ethanol. Total phenolics in extracts were remarkably increased at above 50% of ethanol concentration. Overall yield of oleoresin components increased in proportional to extraction time up to 7 min. Based on the above results, it is indicated that ethanol concentration is a critical parameter in MAE.

To compare the contents of well-known effective constituents, paeoniflorin, albiflorin and benzoic acid, of Korean paeony roots cultivated at different regions, this study was to provide the basic information for the quality evaluation of paeony roots. HPLC analysis showed that the paeoniflorin contents of white paeony roots of 3 years grown at Eui-seong gun, Kyungpook was the highest of 2.06% and red paeony roots of 3 years grown at Im-sil gun, Junpook was the lowest of 1.33%. The highest level of albiflorin contents was 2.04% of red paeony root grown at Ul-jin gun, Kyungpook, while the lowest levels were 0.05% of Eui-seong gun, Kyungpook and 0.06% of Im-shil gun, Junpook. The highest level of benzoic acid contents was 0.12% of red paony roots grown at Choung-do gun, Kyungpook and that grown at Ul-jin gun, Kyungpook was the lowest. Based on the average of three available constituents, the paeony roots cultivated at Kyungpook province was the highest contents of 2.03%, while 1.47% at Junpook province. These results suggest that Kyungpook province is the best region for the cultivation of white and red paeony roots, the combining of three available constituents would be more accurate than use of paeoniflorin only.
