Bunium Persicum

<p>Volatile oil and fatty acids components of six various populations of wild Bunium persicum Boiss. (Bam and Zirkuh/Iran) and cultivated Cuminum cyminum L. (Rayen/Iran; Cukurcak, Taskopru and Asagialicomak/Turkey) species were investigated. The volatile oil content of Bam and Zirkuh populations were 3.9 and 4.7 %, respectively. The analysis of volatile oils by the GC/FID-MSD showed that γ-terpinene (33.62-39.62 %), cuminal (17.9-19.3 %), o-cymene (5.3-11.1 %), benzenemethanol, α-methyl- (7.4-9.5 %), 1-phenyl-1-butanol (6.4-8.4 %) and limonene (6.4-8.6 %) were the major components of B. persicum populations. Rayen, Cukurcak, Taskopru and Asagialicomak populations of C. cyminum had 2.6, 2.2, 2.0 and 2.5 % of volatile oil, respectively. Cuminal (22.8-37.6 %), benzenemethanol, α-methyl- (5.3-22.6 %), γ-terpinene (16.7-19.4 %), β-pinene (11.2-11.9 %) and 1-phenyl-1-butanol (5.4-12.5 %) were identified as the main components of C. cyminum. Fatty acids were detected by the GC/FID. In total, 15 fatty acids were characterised in B. persicum populations from Iran. Petroselinic acid (26.3-52.6 %), lauric acid (16.2-37.0 %) and linoleic acid (18.3-33.0 %) were the predominant fatty acids identified in Iranian populations. C. cyminum populations were rich in the same fatty acids but, the order was: petroselinic acid (47.5-55.5 %), linoleic acid (22.5-25.4 %) and lauric acid (13.4-24.2 %). Monounsaturated fatty acids (27.4-56.2 %) were the major subgroup. Overall, B. persicum populations from Iran and C. cyminum from Turkey were almost similar in fatty acids profile although they had wide diversity in the volatile oils compositional profile.</p>

The effect of dietary conjugated linoleic acid (CLA) in association with two vegetable oil sources on the fatty acids of meat and giblets of broiler chickens was evaluated. Two hundred 21-day-old broiler chickens were distributed in a completely randomized factorial design 2 x 5 (two oil sources, soybean or canola oil; and five levels of CLA, 0.0, 2.5, 5.0, 7.5, and 10.0g/kg). The addition of CLA to the diet resulted in an increase (P<0.05) in CLA deposition in the analyzed tissues. CLA supplementation also reduced (P<0.05) the rate of polyunsaturated to saturated fatty acids in thigh, breast, heart, and gizzard. There was interaction of CLA x oil source (P<0.05). The intake of soybean oil, associated with increasing CLA, resulted in an increase in lipid deposition in edible portions as observed by an increase in the overall content of fatty acids, including CLA, while the use of canola oil, associated with increasing CLA in the diet, resulted in a decrease in lipid content in edible portions, specifically regarding that of saturated fat (P<0.05) in breast meat and liver and in the content of monounsaturated fatty acids (P<0.05) in thigh, breast, liver, and gizzard.

Abstract Lauric acid (LA) is an additive used in ruminant’s diet with the purpose of mitigating the methane effect. However, the presence of a certain amount of LA in the rumen can cause a reduction in the microbial population and ruminal metabolic processes, such as the biohydrogenation. This study aimed evaluate the effect of the LA inclusion in the diet of Nellore on the fatty acids profile of the meat. Thirty-two young Nellore bulls were used with an average age of 24-months. The animals were individually fed with a total mixed ration with 40% of roughage (Cynodon sp. hay) and 60% of concentrated mix, composed with ground corn, soybean meal, urea, mineral premix and LA in 0.0; 0.5; 1.0; 1.5% of inclusion in the total diet dry matter basis. Those amounts constituted the treatments. At the end of the trial, the animals were slaughtered and the meat was stored at -21oC, before analyses. The experimental design was completely randomized, with four treatments and eight replications. The data were submitted to regression analysis, and significance was declared when P &lt; 0.05. There was no effect (P &gt; 0.05) of the inclusion of LA in the sum of saturated fatty acids (∑SAF=43.45±1.55), monounsaturated fatty acids (∑MUFA=41.9±0.29), and polyunsaturated fatty acids (∑PUFA=12.25±1.40). The inclusion of LA in the diets also did not affect the sum of omega-3 fatty acids (∑ n-3=1.05±0.22), omega-6 fatty acids (∑ n-6=3.02±0.49, and the reason n-6: n-3 (2.91±0.12). The atherogenicity (0.65±0.05) and trombogenicity (1.47±0.10) indexes, important indexes to predict heart coronary diseases risk, were not affected by the inclusion of LA in the diet of the animals. The results suggest that LA can be included up to 1.5% (DM basis of total diet) in the diets of Nellore without causing any significant changes in the fatty acids profile of the meat.

1. The fatty acid composition in platelet phospholipids and in the plasma lipid esters as well as the serum lipoprotein lipid concentrations were determined in 67 healthy male subjects in order to establish the relationships between blood lipids and platelets. 2. A positive correlation was found between the concentrations of the triglyceride rich serum lipoprotein lipids and the relative percentage of saturated and monounsaturated fatty acids in plasma. The correlations were also positive between the serum high density lipoprotein-cholesterol concentration and the relative content of linoleic acid in the plasma cholesterol esters and phospholipids. 3. Negative correlations were found between the relative percentage of saturated and monounsaturated fatty acids in the plasma lipid esters versus linoleic acid in plasma and in the platelets. On the other hand there were positive correlations between linoleic acid in the plasma lipid esters and in the platelet phospholipids. These results indicate a direct dietary influence on the platelet phospholipid fatty acid composition. 4. The correlations between the fatty acids of the n −6 series within plasma and platelets as well as between plasma and platelets indicate that a high linoleic acid content is not associated with an increased arachidonic acid concentration. The results also indicate that the limiting metabolic step in the conversion of linoleic acid into arachidonic acid may be located at different levels in plasma and in the platelets.

Overripe tempe is a food product that used by peoples in Indonesia as a food seasoning. So far, overripe tempe received less attention than fresh tempe and research of overripe tempe is rarely done. The objective of the study is to identify the fatty acid compounds of the  fifth day fermentation overripe tempe oil before and after purification . The overripe tempe oil of fifth day fermentation was extracted with soxhletation method using n – hexane solvent, then it was purified. The various fatty acids  of overripe tempe oil were analyzed by GC – MS. The purification process was done by using H3PO4 0,2% and NaOH 0,1N. The result of the study showed that before purification the oil  was composed of eight compounds  are palmitic acid (13,33%),  linoleic acid (77,57%), stearic acid (6,15%), and the five chemical components, Dasycarpidan – 1 - methanol, acetate ,  oleic acid, 9 - Octadecenamide ,Cholestane - 3, 7, 12, 25 - tetrol, tetraacetate, (3?, 5?, 7?, 12?) and  6, 7 – Epoxypregn – 4 – ene -9, 11, 18- triol - 3, 20 - dione, 11, 18 – diacetate have percentage of areas less than 3%. After purification the oil  was composed of palmitic acid (12,38% ), linoleic acid (80,35 %), stearic acid (5,84%), and 17 – Octadecynoic acid (1,42 %) .

The impacts of supplementing with whole oats grain (OG) upon performance and beef quality traits of growing steers grazing oats pasture (OP) were measured. The trial used Angus steer calves (203 kg mean bodyweight) assigned to three treatments: Control, unsupplemented OP (CON); OP plus OG fed at 0.25% BW daily (OG1); and OP plus OG fed at 0.50% bodyweight daily (OG2). All steers grazed the same paddock but were removed momentarily once daily so OG could be fed to each steer individually. Daily intake of OG averaged 597 and 1294 g DM for OG1 and OG2, respectively. Steers were slaughtered after grazing for 130 days to determine carcass characteristics and lipid profiles. In parallel with the grazing trial, four ruminally cannulated steers (613 kg mean bodyweight) were allocated to treatments CON and OG2 (n = 2) to monitor ruminal pH, volatile fatty acids, and NH3-N. Steers fed OG2 had greater (P < 0.01) average daily gain than CON; final liveweight for OG2 steers was significantly higher than both CON and OG1 steers. Although variations in plasma haematocrit and alkaline phosphatase were they did not affect animal performance. Dressing percentage was not affected by the experimental diets but OG2 steers had greater (P < 0.05) marbling scores. Although rib-eye area was numerically greater for OG1 and OG2 than CON steers (8% and 14%), these differences were not significant statistically (P = 0.3493). Intramuscular lipid content of Longissimus dorsi muscle was not significantly increased by OG supplementation but of the intramuscular fatty acids, contributions of vaccenic and α-linolenic acids decreased (P < 0.05). Linoleic acid content was lowest (P < 0.05) for OG1 steers. A no significant decrease in conjugated linoleic acid was detected when more OG was supplemented. No treatment differences in the contributions of eicosapentaenoic acid, docosahexaenoic acid, monounsaturated fatty acids, polyunsaturated fatty acids, saturated fatty acids, n-6 or n-3 to intramuscular fatty acids were detected although the n-6 : n-3 resulted numerically higher (11% and 23%) for OG1 and OG2 steers than CON steers. Rumen pH, NH3-N and volatile fatty acids were not significantly altered by OG supplementation. Supplementing diets of cattle grazing OP improved performance without rumen digestion impairs or inducing substantial changes in the lipid profile of intramuscular fat. Thus, OG supplementation would be expected to improve the efficiency of cattle grazing of OP without substantial changes to ruminal measurements or the lipid profile of beef.
