This study was conducted to investigate the temperatures inside and outside the pot as well as the quality characteristics of traditional Doenjang made by seven different farmers, in the Gyeonggi province during fermentation. The outside temperature of each region in the province was 5 to 10℃ higher in one place, in which fermentation took place inside the glass greenhouse, compared to other regions, while six other places showed similar changes in temperature. The moisture contents of the samples decreased according to the progress of the fermentation period from 53.6~62.3% to 51.0~58.5%. The salinity generally increased from 9.7~14.2% to 10.6~16.3% except for samples B and D, which declined from 17.0~17.2% to 16.6~16.9%. The amino-type nitrogen contents increased from 180.3~557.8 mg% to 437.3~840.7 mg%. The ammonia-type nitrogen contents decreased from 116.3~561.9 mg% to 70.7~149.2 mg%. Overall, the color of Doenjang was similar, but sample E had higher a and b values than the other regions, and the total bacterial count in the entire region was similar.

The objective of this study was to analyze the free sugar contents of ten kinds of fruits and fruit vegetables that were collected from many district in Korea. The analyzed results will be used as basic nutrition component reference to processing. The results were summarized as follows. The total free sugar contents among the ten kinds of fruit vegetables was highest in grape. The contents of glucose, fructose and sucrose were 6.39%, 6.27%, 0.28%, respectively. The average total sugar contents of four cultivar of apple was 11.42% and average fructose contents was 6.13%. The free sugar contents of thirteen samples of the same cultivar of apple were all differing with statistical significance. The average total free sugar contents of eight cultivar of peach was 8.66%. In case of tomato, glucose content was approximately 1.35~2.83% and fructose was 1.26~2.51%. The contents of glucose, fructose and sucrose in paprika were 2.19%, 2.06%, 0.1%, respectively.

Recently,mushrooms have received attention because they are material of nutritious food health-stimulating properties and medicinal effects. For the purpose of application the antihypertensive Pholiota adiposa and S. cerevisiae into development of new functional traditional rice wine, optimal fermentation condition and sensory evaluation of functional traditional rice wines were investigated and further its angiotensin-I converting enzyme(ACE) inhibitory activities were determined. Addition of antihypertensive Pholiota adiposa ASI 24012 into the mash was unaffected to ethanol production. The best acceptability showed in the PS-1 traditional rice wines which was brewed byaddition of 0.1% Pholiota adiposa ASI 24012 fruiting body into mash containing antihypertensive S. cerevisiae and cooked and also showed high ACE inhibitory activity of 78.3%.
