The acceptability of purified stevioside as a sweetner was carried out. The content of stelvioside was $7.30{\sim}17.8%$ of the dry leaf of stevia harvested in Korea and the purified stevioside showed $100{\sim}150$ folds sweeter than sucrose. Improvement of acceptability of the purified stevioside by mixing with other sweetners was as the following order: sucrose>glucose>fructose= invert sugar >saccharin-Na. When 2 kinds of sweetner were mixed stevioside the improvement was the same as one sweetner was mixed with stevioside. The mixture of the stevioside and sodium chloride did not give any off-taste.

The standard operation procedure of mouse lymphoma L5178Y $tk^{+/-}-3.7.2C$ gene mutation assay (MOLY) has been regarded as a sensitive in vitro mammalian cell gene mutation assay that is capable of detecting clastogens as well as mutagens. Using MOLY, one of natural sweetner, stevioside (5mg/ml) and its aglycon, steviol ($340{\;}\mu\textrm{g}/ml$) were evaluated the mutagenicity. Stevioside and steviol did not induce mutagenicity in MOLY. On the other hand, stevioside (250mg/kg, B.W.) and steviol (200mg/kg, B.W.) were also evaluated their ability to induce micronuclei in regenerating hepatocytes and bone marrow cells of ddY mice. From these results, stevioside and steviol did not induce any mutagenic effect both MOLY and in vivo micronucleus test.

In order to provide fundamental data of food circulation policy, we performed monitoring the safety of the imported food which was circulating through Gwangju from March to October, 2005. Acid and peroxide value which are barometers for evaluation of the quality of lipid were investigated in 130 samples of imported oil treatment food. Not-permitted tar pigment and artificial sweetner were investigated in 139 candies by TLC and HPLC. The content of sulfur dioxide in 129 samples of dried fishery products and dried fruits was investigated by Monier-Williams method. In 130 samples of imported oil treatment food, 9 samples (6.9%) were incongruent with acid value, 6 samples (4.6%) with peroxide value and 4 samples (3.1%) with acid value simultaneously with peroxide value. In 139 imported candies, not-permitted artificial sweetner were found in 2 samples (1.4%). In 129 samples in which sulfur oxide was analyzed,4 samples (3.1%) were incongruent. Finally, in total 398 samples in which this study was analyzed, 25 samples (6.3%) were incongruent.

In order to obtain data for use of algin in drink making process solution properties of algin have been investigated at various condition of algin concentration temperature pH and various food additives. At same revolution velosity viscosities of algin were increased as algin concentration raised. Algin solution showed dilatnat type flow in concentration of 0.25% to 0.4% but pseudoplastic type flow in above 0.5% showed dilatant type flow in concentration of 0.25% to 0.4% but pseudoplastic type folw in above 0.5% A maximum viscosity of algin was observed at pH 5.5 and its viscosities were also decreased as the tem-perature increased and heating at 8$0^{\circ}C$ above. Organic acids affected on the viscosity of algin with pH dependently and gel formed in pH below 3.0 Sweetners have no effect to the viscosity of algin. How-ever addition of NaCl and KCL upto 1.0% decreased a little its viscosity and CACl2 MgCl2 and FeCl3 increased the viscosity of algin Glutamic acid decreased the viscosity of algin.

The purpose of this study was to investigate effect of the amounts of rice flour, glutinous-rice flour supplementation, Chinese radish, and the kinds and amount of sweetner on the sensory and objective characteristics of Moo-dduk which is korean traditional cake supplemented with jullienne Chinese radish. The advisable recipe for Moo-dduk was obtained through the various experiments. i) The Moo-dduk blended with rice flour. rice flour 300 g Chinese radish 210 g(70% of rice flour) sugar 30 g(10% of rice flour) salt 3 g(1% of rice flour) ii) The Moo-dduk blended with rice flour and glutinous-rice flour. rice flour 225 g, glutinous-rice flour 75 g(25% of rice flour), Chinese radish 210 g(70% of rice flour) sugar 30 g(10% of rice flour) salt 3 g(1% of rice flour)

To examine the potenital of APM as the sweetner of Kimchi, the change of APM (0.1%) added to Kimchi was monitore during the fermentation of Kimchi as $25^{\circ}C$. The content of APM added to Kimchi was ecreased to the extent of 20% after 20hrs by being decomposed into aspartylphenylalaine and phenylalanine. The decomposition degree of APM during the fermentation was only below 10% caused by the joint effects of lactic acid bacteria and pH and was disclosed as mainly led the reaction of enzymes contained in the raw chines cabbage. The decomposition of APM was inhibited by increasing the concentration of NaCl.

This study examined physiological activity of aronia chung with or without aspartame. High sugar content of food is recognized to induce chronic disease including diabetes and obesity. Sugar was replaced with aspartame to develop low-sugar aronia chung containing 0%, 25%, 50% and 75% aspartame based on sugar content of control in the study. Sweetness was the similar in the chungs with 0%, 25% and 50% aspartame but it was lower in the chung with 75% aspartame. pH was the highest in aronia chung with 75% aspartame as 2.95. Total phenolic content was the highest in aronia chung with 50% aspartame but it was not significantly different with 75% one. Flavonoid content increased with addition of aspartame and it was the highest in the chung with 75% aspartame as 206.60 ㎍ QEAC/mL. Reducing power also showed the same aspect with flavonoid content. However DPPH radical scavenging ability was the highest in aronia chung without aspartame and lowest in the chung with 75% aspartame. This result implies that the addition of aspartame could sustain the sweetness and improve the physiological activity of food at the same time although there is some limitation.

Erythritol is of interest as a low calorie sweetner. Penicillium sp. KJ8l was screened for erythritol producer in nature. The effect of culture conditions on erythritol production by Penicillium sp. KJ81 was examined. This strain produced about 12 g/l erythritol and a small amout of glycerol. Erythritol was not produced from mannitol, arabinose, sorbitol, and xylose but from glucose, sucrose, fructose, mannose, lactose, maltose, and galactose. This strain was able to produce erythritol in a medium containing 60% sucrose but demonstrated the highest productivity of erythritol in a 30% sucrose medium. The highest yield in Penicillium sp. KJ8l was obtained when 0.5% ammonium sulfate was added to the medium containing 30% sucrose and 0.5% yeast extract. Penicillium sp. KJ81 produced 28.2 g/l erythritol when this strain was cultured in the medium containing 30% sucrose, 0.5% yeast extract, 0.5%$(NH_{4})_{2}SO_{4}$ 0.1% $KH_{2}PO_{4}$ and 0.01% $MgCl_{2}$ under the condition of 1 vvm aeration and 200 rpm agitation at $37^{\circ}C$ for 10 days in 5ι jar fermentor.
