Korean Journal of Food Preservation, volume 7, issue 2, 2000, Pages 133~138
The research was conducted to measure the effect of temperature on respiratory and quality characteristics of 'Tsugaru' apple(Malus domestica Borkh) during storage at 4
C and 20
C. Respiration rate of the apple just after harvest was 7.57 mL CO
/kg/h at 20
C. It was decreased rapidly and was 2.86 mL CO
/kg/h after storage for 45 days at 20
C. The apples showed the highest ethylene production rate at 10
C and 20
C after 14 days, and at 4
C after 28 days during storage. Weight of the apple was reduced by 2.9% after 120 days at 4
C and by 6.1% after 45 days at 20
C. Color difference of peel and pH increased with the temperatures but titratable acidity and flesh firmness showed the reverse trends during storage. According to the subjective quality test, it could be suggested that the shelf-life of the apple is 86 days at 4
C, 65 days at 10
C and 37 days at 20

In order to extend the shelf-life of red chili pepper, MA and CA technology were used. In MA storage, red chili peppers(Jinmi and Jangkun) were packaged in 0.03 mm PE film bags(3 kg/bag) having two holes(
2~3 cm) at 2~3
C or 7~8
C. In CA storage, red chili peppers(Jinmi) were stored on following gas composition; 5 or 10% CO
in combination with 2 or 5% O
C, respectively. The changes of weight loss and decay rates during MA storage were less in Jinmi than in Jangkun and less at 2~3
C storage(except O
10% condition) while in CA it decreased after 40 days of storage. Red chili peppers would be stored for 30 days when stored in MA conditions(0.03 mm PE film bag) and for 60 days when srored in CA condition on O
10% based on overall quality of sensory evaluation.

Korean Journal of Food Preservation, volume 7, issue 2, 2000, Pages 145~149
Strawberry and cucumber were dipped with Korean medical herb extracts such as Rheum palmatum L. and Coptis chinensis Franch. to maintain the keeping quality during storage at 5
C and 10
C, respectively. Treatment with 500 ppm solutions gor strawberry retarded weight loss, microbial load increase, and decay during storage. Decay ratio was shown 68.8% for control, 45.0% for Rheum palmatum L. and 42.5% for Coptis chinensis Franch. at 10 days. Strawberry treated with Coptis chinensis Franch. showed a higher hardness and soluble solid content than others. Cucumber treated with 1,000 ppm solutions revealed a different O
concentrations after 16 days. Korean medical herb extracts showed an antimicrobial activity for the quality retention of cucumber during storage. Ascorbic acid content was generally increased till 8 days, but decreased thereafter.

The use of artificially synthesized inorganic manure for the production of fruits and vegetables gives rise to soil contamination as well as noxious effects against human. Changes in quality of strawberry (SN) cultivated with a natural organic manure developed to solve such problems were studied during storage at 4
C for 2 weeks. SN showed higher weight/volume ratio and lower weight loss during storage than strawberry (control) cultivated with commercial synthetic mature. Sweetness was higher in SN (9.2 Brix) than in control (8.2 Brix), and decrease in sweetness during storage was smaller in SN than in control. Redness (b) of strawberry was 32.1 in SN and 30.2 in control, and the redness decreased during storage showing 25.2 and 23.0, respectively, after 2 weeks. Hardness was higher in SN than in control, and decrease in hardness during storage was smaller in SN than in control. Vitamin C content was slightly higher in SN than in control, and mineral contents were generally higher in SN than in control.

Sohn, Mi-Ryeong ; Cho, Rae-Kwang ;
Korean Journal of Food Preservation, volume 7, issue 2, 2000, Pages 155~159
Apple fruit grading is largely dependant on skin color degree. This work reports about the possibility of nondestructive assessment of apple fruit color using infrared(NIR) reflectance spectroscopy. NIR spectra of apple fruit were collected in wavelength range of 1100~2500nm using an InfraAlyzer 500C(Bran+Luebbe). Calibration as calculated by the standard analysis procedures MLR(multiple linear regression) and stepwise, was performed by allowing the IDAS software to select the best regression equations using raw spectra of sample. Color degree of apple skin was expressed as 2 factors, anthocyanin content by purification and a-value by colorimeter. A total of 90 fruits was used for the calibration set(54) and prediction set(36). For determining a-value, the calibration model composed 6 wavelengths(2076, 2120, 2276, 2488, 2072 and 1492nm) provided the highest accuracy : correlation coefficient is 0.913 and standard error of prediction is 4.94. But, the accuracy of prediction result for anthocyanin content determining was rather low(R of 0.761).

Ha, Young-Sun ; Lee, Jun-Ho ; Kim, Su-Il ; Park, Nam-Ho ;
Korean Journal of Food Preservation, volume 7, issue 2, 2000, Pages 160~165
The study aimed to review linerboard compositions of corrugated fiberboard boxes for Oriental melons(Cucumis melon L. var makuwa), analyzing relationships among material compositions, price, weight of boxes, theoretical compression and bursting strength of various liner boards. 19 and 22 different liner boards were currently used for the bleached and the unbleached corrugated boards, respectively. The corrugated board containers with the bleached liners were mostly used in the market although the average price was 10 percents higher than the unbleached. The average compression strength of the bleached. We strongly recommend to redesign the boxes because the average compression and bursting strength of the current boxes were much higher than national packaging standards as much as 70 and 82, respectively.

Korean Journal of Food Preservation, volume 7, issue 2, 2000, Pages 166~170
In order to improve cut-flower export packaging on the distribution process, newly developed T-type(trapezoid type) container was tested and evaluated on the viewpoints of the protection, workability, and economics. T-type container performed better in protection and workability comparing to 0201 and modified 0201 type containers. Especially, load efficiency of T-type container was 33 percent higher than others, indicating that total distribution costs from Korea to Japan can be saved up to 1.7million dollars per year. T-type container is also advantageous because of its superior display performance and environmentally friendly design. We recommend that T-type container is suitable for most of cut-flowers which are usually horizontally packed such as roses, chrysanthemums, and lilies.

and Ethanol as a Co-solvent
Lee, Won-Young ; Chang, Kyu-Seob ; Choi, Yong-Hee ;
Korean Journal of Food Preservation, volume 7, issue 2, 2000, Pages 177~183
A supercritical fluid extraction was performed for the extraction of phenolics from grape seeds which up to now have been discarded. The optimum condition for extraction process was predicted through response surface methodology using central composit experimental design. The extraction amount of grape seed phenolics was increased by increasing extraction temperature, pressure, and concentration of co-solvent (ethanol). The optimum extraction conditions were 84.83
C, 51.50MPa and 1.27% ethanol. The yield of phenolics using SFE was higher with 3 folds than ethanol and 4 folds than hexane but less than 80% methanol. In the respects of food poisoning, the approved solvents were restricted to ethanol and hexane. So, SFE for extraction of phenolics could be powerful alternative method for solvent extraction.

To proceed mass production and improve its quality, we fermented potatoes using pilot system and investigated the changes in components during fermentation. After liquefaction and saccharification of potatoes by Nuruk(group I), crude enzyme(group II) and glucoamylase(group III), sugar contents in all groups were 18brix equally. However sugar contents in group(II) and group(III) after 24hrs decreased deeply to 7.2 and 8.8 % respectively, after 24hrs. Alcohol content in group(I) increased slowly and was the highest such as 6.8% after 48hrs. Fusel oils in all groups were n-propanol, isobutanol and isoamylalcohol. The major fusel oil in all groups was isoamylalcohol. At the early stage of fermentation, free sugars were glucose, maltose and lactose. Glucose decreased deeply during fermentation and at latter of the fermentation, galactose was detected in all groups. The contents of total free amino acid were 516.57~569.98 mg% in group(I), 193.97~292.11 mg% in group (II) and 186.31~270.53 mg% in group(III). The contents of aspartic acid, serine, glutamic acid, alanine, arginine, and histidine were high in all groups.
