Soybean oil was sprayed on Bermuda grass and mixed well. All diets were isonitrogenous. Goats were slaughtered at an average live weight of 60 kg. Our objective was to determine whether dietary soybean oil altered the fatty acid composition and the color stability of goat loin chops (longissimus muscle) after being stored at 2℃ for 9 days. Adding soybean oil (2.5 and 5.0%) to goat diets decreased (p＜0.05) the percentage of trans-11 C18:1 (p＜0.05), C18:1, C18:3, C20:5 (eicosapentaenoic acid), and C22:0 fatty acids. The percentage of cis-9, trans-11 isomer of CLA (conjugated linoleic acid) increased slight1y as the percentage of supplemental soybean oil increased, but the differences across the treatments were not significant. Treatments with soybean oil increased the levels of MUFA (monounsaturated fatty acids) and PUFA (polyunsaturated fatty acids), but decreased the level of SFA (saturated fatty acids). The Hunter L(superscript *) of the loin chops increased, but the pH value decreased with increased soybean oil supplementation.

Each hydrolysate was measured its recovery and evaluated its relative cholesterol uptake (RCU, %) in Caco-2 cells. The higher the recovery represented the higher the yield. The lower the RCU revealed the higher the cholesterol absorption inhibition. The result indicated that intact ISP could further decrease its RCU by hydrolyzing with any of these enzymes. Flavourzyme-ISP hydrolysate had the lowest RCU of 37% and maintained the highest recovery of 58% than the others. The effects of limited ISP hydrolysis using flavourzyme in terms of the degree of hydrolysis (DH, %) on recovery and RCU in Caco-2 cells were also investigated. When the DH was less than 22.8%, the RCU decreased with the increase in DH. However, extensive ISP hydrolysis using flavourzyme to obtain DH higher than 28% did not guarantee enhance the cholesterol absorption inhibition but significantly (p＜0.05) decreased the recovery. According to micelle inspection using a transmission electron microscope, the hydrolysate was clearly incorporated into the micellar membrane but ISP wasn't. This finding suggested that incorporation of the hydrolysate lead to reduce cholesterol solubility during micelle preparation as well as inhibit cholesterol absorption in Caco-2 cells.","PeriodicalId":34946,"journal":{"name":"Taiwanese Journal of Agricultural Chemistry and Food Science","volume":"20 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74352621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The field used in this study is located in Chi-san, at the Kaohsiung District Agricultural Improvement Station, in Southern Taiwan. The soils in this study were subjected to long-term studies, and were treated with organic fertilizer only (OF), chemical fertilizer only (CF), or a combination of organic and chemical fertilizers (IF), all of which were applied continuously. After transplantation, broccoli and cabbage plants were harvested at 75 and 70 days, respectively. The plants were separated into roots, leaves (wrapper leaves for cabbage), and heads. After drying to a constant weight at 65℃, the dry weight, nitrate N, total N, and insoluble N were determined, respectively. The results showed that the growth and N uptake of broccoli and cabbage from the OF-treated plot were the same or even higher than those from the CF and IF plots. The N use efficiency (NUE) for the OF plot was also higher. The NO3(superscript -)-N concentrations of both the entire broccoli and cabbage that received OF treatment were lower than those which received CF treatment. The total N and soluble N concentrations of organic fertilizer-treated broccoli were lower than those of the chemical fertilizer-treated ones; the reverse was true for cabbage. In conclusion, after 11 years of applying organic fertilizer and establishing the soil fertility, the crop yield of OF treatment, in which the application of N fertilizer was based on the mineralization capacity, can be as high as or higher than that of CF treatment, resulting in lower NO3(superscript -)-N concentrations in the plants.","PeriodicalId":34946,"journal":{"name":"Taiwanese Journal of Agricultural Chemistry and Food Science","volume":"34 1","pages":"416-424"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88802258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
