  • This study was done to investigate the effects of different dietary oils on hepatic mitochondrial lipid compositon, adenine nucleotide translocase(AdNT) and ATPase activities in carcinogen treated rats. Sixty male Sprague-Dawley rats, weighing 50∼60g, were fed three different types of dietary oil, beef tallow(BT), corn oil(CO) and sardine oil(SO) at 15% by weight for 14 weeks. Three weeks after feeding rats were intraperitoneally injected with a single dose of diethylnitrosamine(200mg/Kg BW). After five weeks rate fed 0.02% acetylaminofluorene contating diet for 6 weeks, and after seven weeks 0.05% phenobarbital containing diet for 7 weeks. At 14th week, rats were sacrificed and hepatic mitochondrial lipid composition, AdNT and ATPase activities were determined. Percent liver weight per body weight was significantly by carcinogen treatment. Analysis of mitochondrial lipid composition showed that body cholesterol and phospholipid contents were not affected by dietary oils but significantly increased by carcinogen treatment. Individual phospholipid composition as well as phosphatidyl ethanolamine/phosphatidyl choline ratio were altered by either dietary oils or carcinogen treatment. Fatty acid composition was changed by dietary oils but not much by carcinogen treatment. AdNT activity was affected by dietary oils in only carcinogen treated groups. ATPase activity was affected by dietary oils in only carcinogen nontreated groups. These data indicate that both dietary oils and caricinogen treatment can change mitochondrial lipid composition and thereby change AdNT and ATPase activities. Particularly effects of carcinogen treatment on cholesterol/phopholipid ratio, phospholipid compositon and ATPase activity were different among dietary oil groups. Therefore it is suggested that different dietary oils can somewhat modulate the changes of mitochnodrial lipid composition and membrane bound enzyme activites during hepatocarcinogenesis.

  • Grape seed oil was characterized to assess the usefulness in the food industry. Among the various oils, the initial antioxidant activity was the highest for grape seed oil. Heating the oil at $180^{\sim}C$ for 20 min retained 86% of the initial activity. Grape seed and sesame oils showed a low peroxide value, about 2, implying a less oxidative reaction. The oxidation of grape seed oil was increased to a less extent by heat-treatment than other oils. Light exposure for 1 month resulted in a slight decrease in the antioxidant activity of grape seed oil, maintaining 96% of the initial activity. Other oils were all light-susceptible and the activities decreased significantly. The peroxide values of all the oils increased by light exposure, but the extent of oxidation was still the least for grape seed oil. The addition of grape seed oil to perilla oil was very effective, in that the peroxide value was 5-times decreased by 1 : 5 composition of grape seed oil versus perilla oil. These results indicate that grape seed oil can be used as a good cooking oil or an additive for other oils.

  • An experiment was conducted to investigate the effects of dietary acidifier($Lactacid^(R)$) and essential oil($Immunocin^(R)$) on the performance, nutrient metabolizability, small intestinal microflora, IgG level and leukocytes and erythrocytes in broiler chickens. Five hundred males and 500 females broiler chickens($Ross^(R)$) were divided into 20 pens of 50 chickens(25 birds in each sex). Five pens were assigned to each of four dietary treatments: control, diets containing antibiotics(Bacitracin methylene disalicilate), acidifier($Lactacid^(R)$) and essential oil($Immunocin^(R)$) dietary treatments. Birds were fed experimental diets ad libitum 5 wks. Weight gain, feed intake, and feed conversion rate were significantly affected by dietary treatment(P<0.05). Overall weight gain($0{\sim}5$ wks) of $Lactacid^(R)$ treatment was significantly lower than the others. Feed intake was highest(P<0.05) in the control followed by antibiotics, $Lactacid^(R)\;and\;Immunocin^(R)$ treatment. Feed conversion rate of $Immunocin^(R)$ treatment was lowest(P<0.05) followed by antibiotics, $Lactacid^(R)$ treatment and the control. Production indices of $Immunocin^(R)$ and antibiotics treatments were significantly higher than those of the control and $Lactacid^(R)$ treatment(P<0.05). $Immunocin^(R)$ treatment was the highest and antibiotics was lowest in serum IgG level. The number of leukocytes and stress index(neutrophil/lymphocytes) tended to be lower in $Immunocin^(R)$ treatment than others. There were no significant differences in erythrocytes among the treatments. The cfu of E. coli was significantly lower in $Immunocin^(R)$ and antibiotics treatments than $Lactacid^(R)$ treatment and the control. Metabolizability of crude protein was significantly lower in the control than $Lactacid^(R)\;and\;Immunocin^(R)$ treatment while that of NFE was significantly lower in $Immunocin^(R)\;than\;Lactacid^(R)$ and antibiotics treatments. It was concluded that essential oil product $Immunocin^(R)$ is as effective as antibiotics in improving feed conversion efficiency and production index while $Lactacid^(R)$ is not.

  • The purpose of this study is to determine the effect of dietary proteins and fats on the hepatic histological changes, membrane stability, and drug-metabolizing enzyme activities during chemically induced rat hepatocarcinogenesis. Weanling Sprague-Dawley rats were fed the diet containing 20% casein or soy protein isolate and 15% perilla or corn oil for 10 weeks. Hepatocarcinogensis was initiated with diethylnitrosamine(DEN), and the rats were fed diets containing 0.02% 2-acetylaminofluorene(AAF) followed by 0.05% phenobarbital (PB). The scores of histological changes were decreased in treated rats fed soy protein diet compared to those find casein diet. Liver weights were significantly increased by AAF and PB treatment in rats fed casein diets in both oil groups. Glucose 6-phosphatase(G6Pase) activities, an index of membrane stability, were significantly reduced by AAF and PB treatment in rats find casein diets, and were lower in casein diet compared to soy protein diet groups. Especially, the activities were the highest in the rats fed soy protein-perilla oil diet. Lipid peroxide values also were increased by AAF and PB treatment in rats fed casein diet. Aniline hydroxylase activities were not influenced by protein and fat sources. Glutathione-dependent enzyme activities were increased by AAF and PB treatment. Linoleic and arachidonic acid content were increased in rats fed corn oil diet, and linolenic and eicosapentaenoic acid contents were increased in rats fed perilla oil diet. Our results suggest that soy protein isolate inhibit the abnormal histological changes in liver, possibly by maintaining the membrane stability during chemically induced rat hepatocarcinogenesis. Soy protein may be protective against the hepatocarcinogenesis induced by chemical carcinogen.

  • Forty three 7-month old, Barbados Black $Belly{\times}Malin$ crossbred sheep were used for the trial. They were allotted into three treatment groups fed varying levels of oil palm (Elaeis guineensis) frond pellets and commercial sheep pellets. Treatment diets were 80% commercial pellet+20 % (% w/w) oil palm frond pellet (CON group, n=15), 50% commercial pellet+50% oil palm frond pellet (% w/w) (HAF group, n=14) and 80% oil palm frond pellet+20% (% w/w) commercial pellet (OPF group, n=14). The plasma fatty acid profiles from these animals were compared before and after 14 weeks of feeding. Results showed that total unsaturated fatty acid content in the CON group had increased by 10% (p<0.01) from the pre-treatment values. All three treatment groups had significantly different plasma n-6 and n-3 polyunsaturated fatty acid contents at the end of the trial. In fact, the CON group had significantly (p<0.01) more n-6 polyunsaturated fatty acid content compared to its own initial values, and also the values from the HAF and OPF groups. However there was a significant (p<0.01) decline in plasma n-3 polyunsaturated fatty acids in all groups. The final total unsaturated to saturated fatty acid content ratio was significantly (p<0.01) highest in the CON group, demonstrating the high plasma unsaturated fatty acid content in these animals. This study shows the plasma unsaturated fatty acids in sheep can be increased by dietary manipulation.

  • Sucuk is the most popular dry-fermented meat product. Sucuk has a relatively high fat. Poppy seed oil as animal fat replacer was used in Turkish sucuk and effects of its use on sucuk quality were investigated. There was a significant (p<0.5) treatment × ripening time interaction for moisture, pH (p<0.05) and 2-thiobarbituric acid reactive substances (TBARS) values (p<0.01). Increasing poppy seed oil level decreased (p<0.05) TBARS values. Addition of poppy seed oil to the sucuks had a significant effect (p<0.01) on hardness, cohesiveness, gumminess, chewiness and springiness values. Cholesterol content of sucuks decreased (p<0.05) with poppy seed oil addition. Using pre-emulsified poppy seed oil as partial fat replacer in Turkish sucuk decreased cholesterol and saturated fatty acid content, but increased polyunsaturated fatty acids. Poppy seed oil as partial animal fat replacer in Turkish sucuk may have significant health benefits.
