This study was conducted to evaluate the combined effect of heating and gamma irradiation on the shelf-stability and quality of kimchi during storage at
. The optimum condition for heat treatment of kimchi was considered at
for 30 min. Irradiation after kent treatment was effective to inhibit the growth of microorganisms and prevent the quality change of kimchi during storage. In particular, microorganisms of kimchi co-treated with heat and 20 kGy-irradiation were not detected and sensory scores of that were the highest after storage at
for 14 days. Therefore, combination treatment of heat and irradiation was considered as the effective method to improve the shelf-stability of kimchi in the accelerated condition.

Korean Journal of Food Preservation, volume 13, issue 5, 2006, Pages 581~588
Dynamic changes of free sugar and amino acid in the mixture of red bean paste sediment by corn syrup concentration and heating conditions were monitored. Glucose and fructose contents of red bean paste increased with an increasing blown color intensity. Amino acid content was affected by the heating temperature, increased with an increase in browning color intensify. Browning color intensity of each samples increased up to
, but decreased above
. This result was the same tend as changes of glucose and amino acid. The result of correlation coefficients among free sugar amino acid and browning color intensity show that increase in browning color intensity was not correlated directly with changes of free sugar and amino acid content. It seems that the contents of free sugar and amino acid resolved from saccharides and protein were much mote than contents nea for browning reaction.

The highest value was shown in outward leaf in Wineter Pride (12.70 mg/100 g fresh wt.) and core leaf in 55 Days cultivars (18.60 mg/100 g fresh wt.). leaf pare were 1.7-9.0 times higher in vitamin U levels than those in midribs in both cultivars. levels of vitamin U in stored Chinese cabbages increased with storage time. Moreover, two cultivars used far this experiment showed different pattern during storage. In Winter Pride, vitamin U levels sharply increased in leaf and midrib of cote part during storage. This value reached about 2.5 times for leaf and 4 times for midrib compared to the levels of initial storage time in core part In 55 Days cultivars, outward leaf showed an increased level of vitamin U of 1.8 times compared to that of 1 month storage time. Methionine known as a precursor of vitamin U synthesis did not showed clear relationship with vitamin U levels. Methionine was either not detected or at negligibly low levels in Chinese cabbages during storage. Methionine may not play a role in an increase of vitamin U during storage of Chinese cabbages at
. No clear relationship of free amino acids and soluble sugars for vitamin U accumulation during storage of Chinese cabbages was shown in this study.

Korean Journal of Food Preservation, volume 13, issue 5, 2006, Pages 629~633
Pinus rigida Miller leaf extract (PRLE) showed antimicrobial activity remarkably against food pathogenic and spoilage bacteria at concentrations of
. Alcohol-soluble PRLE had higher antimicrobial activity against Staphylococcus aureus and E-coli than any other-soluble PRLE such as butanol, ethyl acetate, ether and water. As PRLE concentration increased alcohol-soluble PRLE increased the remarkable inhibitory zone of microbial growth on the microbial media. PRLE showed good stability against temperature and pH in the range of
, respectively. This may indicate that PRLE can be a potential anti-microbial agent for industrial application. In addition, SEM of Listeria monocytogenes suggested that it antimicrobial component would perturb the functions of microbial cell membranes synergistically. In the feeding experiment the formaldehyde content in the serum of formalin-fed and PRLE-treated me decreased remarkably due to the lysis of formaldehyde and the rate of hemoglobin biosynthesis was recovered to the orignal state within a short breeding time.

Lee, Jae-Joon ; Park, Se-Young ; Lee, Myung-Yul ;
Korean Journal of Food Preservation, volume 13, issue 5, 2006, Pages 634~642
This study was performed to investigate the effects of lotus root ethanol extinct (LRE) on 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity in vitro, and lipid metabolism in the serum and liver of rate fed normal or high cholesterol diet in vivo. LRE (200 mg/kg/day and 400 mg/kg/day) was administered only to rats with fed high cholesterol diet for 6 week. We divided into 6 groups: normal diet group (NC), high cholesterol diet group (1% cholesterol and 0.25% sodium cholate)(HC), LRE 200 mg/kg treated group (NC-LREL), LRE 400 mg/kg teated group (NC-LREH), high cholesterol diet and LRE 200 mg/kg treated group (HC-LREL), and high cholesterol diet and LRE 400 mg/kg teated group (HC-LREH). LRE significantly inhibited the HMG-CoA reductase activity in a concentration-dependent manner in vitro. The body weight gain and liver weight of the high cholesterol diet group were higher than the normal diet group whereas the groups administered LRE were gradually decreased. The high cholesterol diet group increased serum triglyceride, total cholesterol, free cholesterol and LDL-cholesterol levels, and decreased atherogenic index, HDL-cholesterol and phospholipid levels as compared with the normal diet group. LRE administrated groups were increased in serum HDL-C/T-C, HDL-cholesterol and phospholipid levels, and decreased serum triglyceride, total cholesterol, free cholesterol, and LDL-cholesterol levels as compared with the high cholesterol diet group. These effect of LRE within the high cholesterol diet groups were concentration-dependent manners. There were no differences in the levels of serum triglyceride, total cholesterol, phopholipid, HDL-cholesterol and free cholesterol between normal diet groups. The hepatic LRE administrated groups than in the high cholesterol diet group. Teken together, it is suggested that LRE exerts hypocholesterolemic effect by reducing serum cholesterol concentration in rats with high cholesterol diet-induced hypercholesterolemia.

Korean Journal of Food Preservation, volume 13, issue 5, 2006, Pages 649~654
To enhance beneficial effects of citron fruits, anticancer and antioxidant activities of citron fruits extracts were assessed with or without ascorbic acid. Total phenolic acids and flavonoids of fruits peels and flesh extracts were determined. Fruits peels contained more phenolic acids and flavonoids than those detected in flesh extracts. Scavenging activities of 1,1-diphenyl-2-picrylhydrazyl radicals and reducing powers were increased depending on the concentration. The antioxidant activities on oxidation of linoleic acid emulsion incubated at
were increased but the effect was small to that of butylated hydroxy toluene and ascorbic acid. The anti-tumorigenic effect of these compounds were investigated. They were shown to inhibit the in vitro proliferation of four human tumorigenic cell lines, HT-29, MCF-7, DU-145 and HepG2, in a doso-dependent manner. This study demonstrated that the antioxidant and anticancer activities of citron fruits extracts were derived from their phenols and flavonoids.
