Lack Of Information

The need of better labelling of fats in processed animal origin products is urgent. The lack of information makes it possible to exclude n-3 fatty acids in preparations of foods. The higher fat content, the higher n-6/n-3 ratio seems to be a rule. It is desirable to broaden the labelling into which oils have been used when foods are processed. The dietary balance of n-6 and n-3 fatty acids is important for homeostasis and normal development in humans. The ratio between n-6/n-3 fatty acids suggested to be evolutionary developed is between 1 and 4. The main conclusion is that the fat sources used during processing and preparation of convenient foods have the largest impact on the food FA content and composition. A proposal is therefore that this should be declared on the product label especially the n-3 FA content. It is also of large importance to increase consumption of freshwater fish fed suitable feeds containing n-3 fatty acids in central Europe to enable a generally lower n-6/n-3 ratio in the human diet. Therefore optimizing feeds to freshwater fish in culture is urgent and important.

Abstract The lipid composition of Piqui (Caryocar coriaceum) seed oil and pulp oil was analyzed and found to contain triacylglycerols (95.1/95.3%) as major components followed by free fatty acids (1.7/1.6%), diacylglycerols (1.6/1.5%), squalene (0.3/0.3%) and monoacylglycerols (0.1/0.1%). Phospholipids were found only in seed oil (0.2%). They were identified as phosphatidylethanolamine and phosphatidylinositol. The sterol fraction (0.1/0.1%) contained stigmasterol and β-sito-sterol. In seed oil triacylglycerols the C-53 molecular species were dominated (52.8%) follow ed by C-55 (37.7%), C-57 (6.9%) and C-51 (2.6%) in minor quantities. In pulp oil triacylglycerols C-55 (51.7%) was predominant followed by C-53 (30.6%) and C-57 (17.7%). Palmitic (16:0) and oleic (18:1) acids were always the major fatty acids in both oils. In seed oil their quantities were nearly the same, whereas in pulp oil oleic acid was predominant. Composition of Lipids of Piqui (Caryocar coriaceum Wittm.)

The sensitivity of Listeria monocytogenes Scott A and ATCC 19114 to antimicrobial compounds was altered when bacterial membrane lipid composition was modified by growth in the presence of added fatty acids. Analysis of cellular fatty acid composition by gas-liquid chromatography indicated that L. monocytogenes Scott A cells contained 0.97, 2.32, 0.81, and 0.72% (relative) of C14:0, C16:0, C18:0, and C18:l, respectively. In the presence of exogenously supplied C14:0, C16:0, C18:0, and C18:l, the percentages increased to 14.03, 30.92, 16.30, and 27.90%. Average MICs for L. monocytogenes Scott A and ATCC 19114 to sodium chloride, tertiary butylhydroquinone, methyl paraben, and propyl paraben were 10.0%, 81, 1406, and 544 μg/ml, respectively. Growing either strain in the presence of 50 μg/ml of either exogenously added C14:0 or C18:0 fatty acids increased their resistance to the four antimicrobial compounds. However, growth in the presence of C18:1 led to increased sensitivity to the antimicrobial agents. The results indicate that the susceptibility of L. monocytogenes to antimicrobial agents is related to the lipid composition of the cell membrane. Consequently, food preservation processes which alter fatty acid composition of L. monocytogenes could result in changes in antimicrobial susceptibility.

Optimum Growth Temperature

Lipid composition of three Arthrobacter strains (mesophilic, psychrotrophic, and psychrophilic strains) grown at their optimum growth temperature was studied. Great differences appeared only in the nature of their fatty acids: the psychrophilic strain synthesized less linear acids, C17 acids, and more iso isomers than the other two strains.Incubation of the three strains at temperatures below their optimum resulted in variations only in proportion of the different fatty acids: increase of the ratio of unsaturated, of branched, and of short-chain fatty acids.The relation between lipid composition and ability to grow at temperatures around 0 °C is discussed.
