The purpose of this study was to investigate the effects of garlic or lemon juice on the lipid oxidation of fish oil as antioxidants and color difference of fish muscle. The samples was treated with garlic or lemon juice by the amount 5%(w/w) or 10%(w/w) of fish muscle were stored at $4\pm$1^{\circ}C$$ and $-18\pm$2^{\circ}C$$ for 10 and 40 days, respectively. The results of this study were as follows; 1. pH of fish muscle had little change during all the storage time at $-18\pm$2^{\circ}C$$. pH of the fish muscle was decreased within 5 days and then was increased untreated or treated with garlic juice at $4\pm$1^{\circ}C$$. 2. Lipid oxidation of fish was measured by POV and TBA value. Both POV and TBA value of the sample treated with garlic juice were generally lower than those of the sample treated with lemon juice and the sample treated with 5f% garlice or lemon juice was lower than the sample treated with 10% garlice or lemon juice. 3. Lightness of the sample treated with loft lemon juice was the highest and that of untreated sample was the lowest during all the storage time at $4\pm$1^{\circ}C$$. As the storaging periods at $4\pm$1^{\circ}C$$, redness of the samples treated with 5% garlic or lemon juice were higher than that of the samples treated with lO%) garlic or lemon juice. Yellowness of the samples treated with 10% garlic or lemon juice showed the highest. Yellowness of the samples treated with lemon juice was higher than that of samples treated with garlic juice.

This study was designed to investigate the effects of Garlic Jug A Jii, a popular processed food for Korean was given of HCI-ethanol in rats as experimental Model. Oral administration HCI-ethanol to fasted rats produced extensive necrosis in the gastric mucosa. Pretreatment with garlic juice and 3 week stored Garlic Jang A Jii juice prevented such necrosis and the effects were dose-dependent. The effects of garlic Jang A Jii juice comparing with raw garlic juice were reduced but statiscally significant differences were not found. 5 week-stored Garlic Jang A Jii was inhibited the formation of gastric mucosal injury. Comparing with garlic Jug A Jii for 3 weeks, while garlic Jang A Jii juice and 1 : 10 diluted garlic Jang A Jii juice did not show significant shifts but the effects of 1 100 diluted garlic Jang A Jii was decreased. Oral administration of disulfide prevented the gastric mucosa injury whereas sulfhydryl blockers such as N-ethylmaleimie and indomethacin was decreased on gastric mucosa protective effect. The content of diallyl disulfide was 1.41mg% in raw garlic, 0.96mg% in garlic Jang A Jii for 3 weeks. The content of diallyl disulfide was gradually reduced according to the elapse of storage period.

This study was conducted to understand the inhibitory garlic and ginger against the growth of food born pathogenic bacteria. Juice was prepared from the raw spices by using an electric homogenizer and membrane filter. Dry-powdered spices were treated with double distilled water and 70% ethanol to extract the antibacterial substances, respectively. Growth inhibitory effects of juice and extracts of the spices were monitored by using bacterial strains such as B. subtilis, L. moncytogenes, S. aureus,E. coli O157 : H7, P. aeruginosa, and S. typhimurium. On a solid medium where E. coli and S. aureus cells were grown, ginger juice formed inhibitory zone at the concentrations of 2-10% by paper disc test. The Bone formed by ginger juice was wider and more transparent than that formed by garlic juice on the same concentration.1. monocytogenes and B. subtilis were more sensitive to garlic juice than others, and stopped growing at 2% garlic juice. Ginger juice showed the growth inhibition by 30-50% at 1.0% concentration. On the contrast, P. aeruginosa which resisted to the garlic juice was the most sensitive to ginger juice. Water extract of garlic was not effective to inhibit the bacterial growth, while 2% ginger extract completely inhibited the growth of E. coli and S. aureus. Alcohol extract of ginger inhibited the growth of bacteria at the concentration of 0.3%. This growth inhibition is almost 10 times lower than that of the garlic extract. It was clear that ginger had more potential than garlic as an inhibitor to control the growth of the indicator organisms.

This study was carried out to find optimum substitution amounts of garlic juice for the purpose of garlic-Yackwa development. Five experimental groups containing 0 t.s, 1/2 t.s, 1 t.s, 1 and 1/2 t.s, and 2 t.s of garlic juice per 1 cup of flour were compared with basic group containing 2 t.s of ginger juice per 1 cup of flour (ginger-Yackwa), by Hunter's colorimetry, texture profile analysis and sensory evaluation. In Hunter's color value, Yackwa, substituted garlic juice from 1/2 t.s to 2 t.s per 1 cup of flour for ginger juice, were lower than ginger-Yackwa. The higher amounts of garlic juice in garlic-Yackwa showed the lower tendancy of L and a values. The b value of garlic-Yackwa containing from 0 t.s to 2 t.s of garlic juice was higher than that of ginger-Yackwa. The higher amounts of garlic juice in garlic-Yackwa showed the higher tendancy of b value. In the texture characteristics, hardness, adhesiveness, springiness and chewiness of all garlic-Yackwa were significantly lower than those of ginger-Yackwa. Cohesiveness of garlic-Yackwa containing from 1 t.s to 2 t.s of garlic juice was significantly higher than that of ginger-Yackwa. Gumminess of Yackwa with garlic juice was higher ($1_{1/2}$ t.s, 2 t.s) than that of ginger-Yackwa, or lower (0 t.s∼l t.s) than that of ginger-Yackwa. The higher amounts of garlic juice in garlic-Yackwa showed the higher tendancies of hardness, cohesiveness and gumminess, while springiness and chewiness showed vice versa. In sensory evaluation, the higher amounts of garlic juice in garlic-Yackwa showed the better color, appearance, flavor, taste and overall acceptability. Especially garlic-Yackwa with 2 t.s of garlic juice showed the best color, appearance, taste, overall acceptability among them. Garlic-Yackwa with 2 t.s of garlic juice evaluated the best, while ginger-Yackwa evaluated the worst. In conclusion, these results indicated that 2 t.s of garic juice per 1 cup of flour could be very useful as a substitute for ginger juice in developing garlic-Yackwa.

It was attempted to observe the effect of garlic on the hepatic purine metabolizing enzymes in this study. The activities of adenosine deaminase, guanase, and uricase in rats were not changed significantly following the feeding of 5% garlic juice. Whereas, garlic juice inhibited significantly the hepatic xanthine oxidase activity compared to control group with the lapse of treated-period. The orate level of serum in rats was significantly decreased by the treatment of garlic juice. The above inhibitory effect of garlic was greater in boiled garlic juice than fresh garlic juice-treated group. These results indicated that, according to the chemical properties of allicin which is unstable in heat, other components than allicin in garlic may regulate the hepatic purine metabolizing enzymes.

Forty-eight 40-wk-old Hi-sex laying hens were individually caged in an environmentally controlled house to evaluate the effect of garlic (Allium Sativum) juice administration on egg production, egg quality, and yolk cholesterol. Garlic juice was prepared by blending pealed garlic cloves with distilled water (1:1, w/w). Hens were randomly divided into four equal groups; one served as a control and the other three groups were individually gavaged, 3.75 ml, 7.5 ml, or 15 ml garlic juice, three times a week, which respectively represented 0.25, 0.50 and 1% of body weight. Egg production was recorded on a daily basis; egg weight, albumen height, albumen and yolk pH, Haugh unit, and bacterial count of E. coli-challenged eggs were recorded at day of oviposition (day-1) and after 5 and 10 days of storage at room temperature. Yolk cholesterol content was analyzed for five successive weeks. Garlic juice increased (p<0.05) egg weight and mass with no change in egg production intensity. Garlic juice administration recorded higher (p<0.05) albumen height and improvement in Haugh unit. Also, eggs from garlic-treated hens recorded lower (p<0.05) albumen and yolk pH when compared to eggs collected from control hens. Garlic reduced (p<0.05) the $log_{10}$ of bacterial count in egg contents linearly when challenged with E. coli. Egg-yolk cholesterol content was not influenced by garlic juice administration. It is concluded that garlic juice improved performance characteristics and may increase egg shelf life as indicated by egg quality improvement and lower bacterial count of E. coli-challenged eggs. The levels of garlic juice used in this study were insufficient to influence egg yolk cholesterol.

In order to investigate antimicrobial substances from natural spices, the effects of garlic juice and ginger juice on the growth of microorganisms were investigated. It was showned that garlic juice inhibited the growth of bacteria, yeasts and fungi but ginger juice did not inhibit the growth of bacteria and yeasts. As result of concentration effect of garlic juice on the growth of microorganisms, the higher concentration of garlic juice was employed, the more growth inhibition was obtained. Comparing the specific growth rate at various concentration of garlic juice, the inhibition effect on yeast appeared much higher than that on bacteria.
