  • Obesity is caused from an imbalance between energy intake and expenditure, which may lead to pathologic growth of adipocytes and accumulation of fat in tissue. We examined the inhibitory effects of Eriobotrya japonica leaf and seed extracts on lipid absorption in vitro and fat accumulation during the differentiation of 3T3-L1 to adipocytes. 3T3-L1 preadipocytes were stimulated with DMEM media containing 10% FBS, 0.5 mM 3-isobuthyl-1-methyxanthine (IBMX), $5\;{\mu}g/ml$ insulin, and $1\;{\mu}g/ml$ dexamethasone for differentiation to adipocytes. E. japonica leaf extract at concentration of 0.5 or 1 mg/ml inhibited pancreatic lipase activity. The cell viability of 3T3-L1 adipocytes slightly reduced about 3% by treatment of E. Japonica leaf and seed extracts. The leaf and seed extracts of E. japonica effectively inhibited the accumulations of lipid droplet and expression of $C/EBP{\alpha}$ promoting adipogenesis. Thus, this data suggest that E. japonica leaf and seed extracts inhibit fat accumulation through regulation of $C/EBP{\alpha}$, and leaf extract is more effective in lipid absorption and adipogenesis than seed extract.

  • The role of fat is important from nutritional standpoint. The physiological functions of fat are energy yielding as well as the carrier of fat soluble vitamins, with special activities of essential fatty acids. It is fortunate that Korean families prefer to use vegetable oils rather than those from animal origin. But the problems are focused on better qaulity of food oils with attempt to exploit the available resources. This study was undertaken to inevestigate the fatty acid compositions of Korean origin both from conventional and unconventional resources of gas-liquid chromatography. The results obtained are as follows. 1. The total lipid contents of seeds of red pepper, Korean squash, sesame, perilla (var Japonica), and Korean pine nuts and walnuts were 24.3%, 56.6%, 56.4%, 46.9%, 69.8%, and 67.2%, respectively. 2. The saponification numbers of samples ranged from 190 to 200. It showed that the mean molecular weights of fatty acids composing the lipids were very much closed each other. 3. Iodine numbers of varing seed oils ranged from 96.5 of Korean squash seed oil to 124.6 of walnut oil. Oils obtained from squash seeds and sesame seeds showed significantly lower value, while others ranged from 122 to 125. 4. In the fatty acid compositions, squash seed oil was composed mainly of unsaturated fatty acids, 74.9% of which was oleic acid, whereas red pepper seed oil, pine nut oil, and sesame oil contained linoleic acid as a major component showing 64.4%, 56%, 48.8%, and 47.8%, respectively. In perilla seed oil, the amounts of linoleic and linolenic acids were 14.1% and 58%, respectively which meant nearly three-fourths of the total fatty acidsbeing the unsaturated essential fatty acids. This study will encourage the use of these conventional and unconventional vegetable oils which have highr ratios of polyunsaturated to saturated fatty acids.

  • The purpose of this study was to determine the content attributes and sensory characteristics of ice cream flavored with lotus leaf and seeds (Nelumbo nucifera Gaertner). Analysis of freeze dried lotus leaf powder produced the following technical results: Freeze dried lotus leaf powder contained moisture 12.2, crude protein 5.9, crude fat 1.2, crude ash 7.0, crude fiber 13.4g/100mg; raw lotus seed powder contained moisture 65.0, crude protein 8.2, crude fat 0.3, crude ash 1.0, crude fiber 10.8g/100mg; freeze dried lotus seed powder contained moisture 14.0, crude protein 17.1, crude fat 1.9, crude ash 4.0, crude fiber 2.8g/100mg. Lotus seed was processed by 4 methods: freeze dried, roasted, freeze dried peeled inner layer, cooked cut peeled inner layer. Analysis of the color value produced the following technical results: freeze dried lotus leaf powder were L(lightness) 14.5, a(redness) 4.4, b(yellowness) 24.0; freeze dried lotus seed powder L 57.3, a 14.4, b 12.0; roasted lotus seed powder L 52.7, a 22.5, b 11.9; freeze dried lotus seed peeled inner layer L 60.0, a 1.4, b 12.3. Proportional lotus ingredients used for ice cream were 1%, 3%, 5%, 7%, 10% for lotus leaves and 1%, 3%, 5% for lotus seeds. The maximum over run ratio for lotus leaf ice cream was 45.3~56.9% at 20~25 minutes operating time. Over run was significantly decreased by increasing the contents of lotus leaf powder. A maximum over run ratio for lotus seed ice cream was 46.1~54.3% at 20~25 operating time. Over run was not significantly different based on content of lotus leaf versus lotus seed. Sensory evaluation of lotus leaf ice cream produced the following results: the highest score was for color of 4.42 and the lowest score was for sweetness of 3.30. The total mean score significantly decreased by increasing the content of lotus leaf powder. Sensory evaluation of lotus seed ice cream produced the following results: the highest score was for cooked cut peeled inner layer type and the lowest was for freeze dried type 3.86. The sensory scores were not significantly different based on the content of lotus seed. Texture was evaluated highest with a rating of 4.21 and the taste was evaluated lowest with a rating of 3.68 For whole evaluation. This study concluded that lotus leaf ice cream demonstrates relative strength in terms of color and taste, and a relative weakness in terms of over run and sweetness. Suitable content of lotus leaf ranged from 1~5%. The lotus seed processed by the cooked cut peeled inner layer method received a higher rating than dried powder for lotus seed ice cream.

  • Seventy-two crossbred pigs weighing an average of 41.5 kg were assigned on the basis of sex, weight and litter to one of four dietary treatments in a factorial (4 treatments${\times}$2 sexes) arrangement. The control diet was based on barley and soybean meal while the experimental treatments consisted of diets in which a portion of the dietary protein was supplied by 20% of a 50:50 blend of extruded ($130^{\circ}C$ for 20 to 25 sec) peas and full-fat canola seed, 20% of a 50:50 blend of unextruded peas and full-fat canola seed or a diet containing 10% peas, 6% canola meal and 4% canola oil (to equal the level of canola oil provided by 10% whole canola seed). Digestibility coefficients for dry matter, crude protein and gross energy were significantly higher (p<0.05) for the control diet than for the other three diets. Extrusion produced no beneficial effects (p>0.05) on nutrient digestibility and there were no differences in digestibility between the diet based on intact canola seed compared with the diet containing canola meal and oil. Choice of protein supplement had no significant effects on gain, feed intake or feed conversion during the grower or finisher phases and over the entire experimental period. Extrusion of the pea-canola blend produced no beneficial effects on pig performance as the performance of pigs fed either the extruded or unextruded blend of peas and canola seed was similar. In addition, the performance of pigs fed diets containing intact canola seed was similar to that of pigs fed canola meal and oil. Castrates gained faster and consumed more feed than gilts (p<0.05). However, their feed conversion was poorer than that of the gilts during the finisher period. There were no significant differences in carcass traits between pigs fed the control and any of the experimental treatments. Extrusion had no effect on carcass traits and the carcasses of pigs fed canola meal and oil did not differ from those of pigs fed whole canola seed. Castrates had a significantly lower dressing percentage, lower estimated lean yield but greater loin fat depth than gilts (p<0.05). The results of this experiment indicate that peas in combination with canola seed or canola meal are an acceptable alternative to soybean meal as a protein supplement for use in growing-finishing swine diets. Extrusion did not appear to have any beneficial effects on the nutritional value of the canola seed-pea blend as nutrient digestibility, growth performance and carcass traits were similar for pigs fed the unextruded blend of peas and canola seed compared with the extruded product. Since the process adds to the cost of the raw products, its use is unlikely to be economical.

  • Dynamic parameters of biochemistry including the contents of soluble carbohydrate (SC) , crude fat (CF) , fatty arid (FA) and soluble protein (SP) in American send (Panax qufnquelolium L.) seed are reported in the present paper. When embryo ratio (ER) increased from 7.31 to 20.48%, the SC content decreased from 4.08 to 1.16%. After that, SC content changed little. The CF content decreased successively from 34.50 to 14.40% from the beginning to the end during the embryo afterripening. The changes of FA content did not correlate with that of ER and the changing range of SP content was not large during the seed stratification. All of these may provide some information for understanding the dormancy mechanisms of American seng seed.
