Storage Roots

Storage roots of `Jewel', `Centennial' and `Beauregard' were chilled at 5C for 0, 10, 20, 30 or 40 days. After chilling, the roots were placed at 21C for two days to allow hardcore development. Hardcore was measured as weight of root that remain hard after boiling for 45 minutes. Hardcore and fatty acid composition of total lipids were compared for the three cultivars. Hardcore was present at 10 days in both `Jewel ' and `Centennial' and at 20 days for `Beauregard'. Severity of hardcore increased with time of chilling. Linoleic acid content of 'Beauregard ' was higher for the 0, 10, and 20 day sampling periods, and decreased to a level equal to that found in 'Jewel ' and `Centennial'.

In 1990ys antiatherogen, antioxidant and anticarcinogen effect of conjugated linolacids (CLA) was detected. From this reasons, our aims in this study were producing pork rich in CLA and studying the change of fatty acid composition of the produced pork cooked different kind of fats. For frying palm and sunflower oil and swine fat were used. Thigh was cutted for 100 g pieces. Meat pieces were fried at 160 °C for 1 and 8 minutes. Estimation of frying data it was determined that higher (0.13%) CLA content of pork was spoiled (60-70%) except in case of swine fat cooking,because it is extremly sensitive for oxidation and heating. Swine fat has higher (0.09%) CLA content than plant oil, protecting the meat’s original CLA content. Cooking in swine fat did not have significant effect on fatty acid composition of meat. Low level of palmitic acid contect of sunflower oil (6.40%) decreased for half part of palmitic acid content of pork (24.13%) and it produced cooked meat with decreased oil acid content. Contrary of above, linoleic acid content of fried meat was increased in different folds as compared to crude pork. If it was fried in sunflower oil with high level linoleic acid increased (51.52%) the linoleic acid content in fried pork. The linoleic acid content of the high level CLA pork increased four times (48.59%) to the crude meat (16.59% and 12.32%). The high palmitic acid content of palm fat (41.54%) increased by 60% the palmitic acid content in fried pork, low stearic acid (4.44%) and linoleic acid content (10.56%) decreased the stearic and linoleic acid content of crude meat.

Linoleic Acid Content

This study was conducted to compare fatty acid composition and content of conjugated linoleic acid (CLA) in different regions of sheep carcasses. Lambs of the Dağlıç breed were used for this purpose. Subsequent to a 68-day period of intensive fattening, fatty acids were examined in samples taken from the legs, shoulders, breasts, and ribs of lamb carcasses. According to the analysis, in leg, shoulder, breast, and rib, respectively, total saturated fatty acids (SFA) were found to be 40.38, 42.69, 42.56, and 40.27%, unsaturated fatty acids (MUFA) were found to be 40.38, 44.17, 46.17, and 49.50%, polyunsaturated fatty acids (PUFA) were found to be 4.79, 4.29, 3.80, and 3.72%, and CLAs were found to be 1.49, 1.69, 1.53, and 1.59%.

Kernel Color

Four cultivars of pecan [Carya illinoinensis (Wangenh.) K. Koch] were studied for 3 years to determine if variations in yield influence fatty acid composition of kernels. Trees used in the study are part of the U.S. Dept. of Agriculture, Agricultural Research Service Historical Block, a test orchard planted in randomized block design with four blocks, having one single-tree replication per block and containing 36 cultivars. Four trees of each of four cultivars (`Cheyenne', `Mohawk', `Pawnee', and `Osage') were used in this test. Trees were in their 5th to 7th leaf from grafting and showed patterns of increasing yield over time for each cultivar. `Osage' was earliest to mature nuts each year and produced nuts with the lowest linoleic acid content. `Cheyenne' was latest to mature nuts and had nuts with the highest linoleic acid content. Oleic acid composition varied with yield in `Osage' and `Pawnee': as yield (kilogram/square decimeter trunk area) increased, oleic acid content decreased. Kernel color, as determined by a Hunter LabScan 5100 Spectrocolorimeter, varied in relation to fatty acid composition for `Osage' and `Pawnee': as oleic acid content increased, kernel lightness decreased. High oleic acid content and light kernel color are associated with high-quality pecans. The pattern of decreasing oleic acid content associated with increasing kernel lightness raises questions concerning the role kernel color evaluation should play in selecting high-quality pecan cultivars.
