Lipid and fatty acid composition of turkey liver, skin and depot tissue

Abstract

Total lipid and phospholipid contents of liver, skin and depot fat from yearling hen turkeys have been studied. Liver lipid averaged 88.5 mg/g wet tissue; skin, 385.0 and depot fat, 753.5. Phospholipids comprised 32.05% of total lipid of liver, but only 0.81% of skin and 0.46% of depot fat. Fatty acids of liver differed from those of skin or depot fat by larger amounts of 16∶0, 18∶0, 20∶4, 22∶0 and 24∶0, and smaller amounts of 16∶1, 18∶1, 18∶2, 18∶3 and 20∶0. Similarity existed between skin and depot fat.

Total Fatty Acid Composition of Duck Fatty Tissues

“…Although actual quantitation was not performed, visual observations of revealed spots was the basis of this conclusion. These findings are consistent with those reported by Katz et al (1966) and Marion et al (1971) for chicken and turkey lipids, respectively.…”

“…Data indicate that only five fatty acids deserve major considerations: oleic>palmitic>linoleic>stearic>palmitoleic. Individual percentages obtained are similar to those presented by Marion et al (1971) for turkey fat, by Barford et al (1965) for chicken fat, and by Mecchi et al (1956a) for duck fat. The order of level of major fatty acids is also about the same.…”

“…reported describing the glyceride and fatty acid composition and other characteristics of chicken and turkey fats (Hilditch et al, 1934;Barford et al, 1965;Katz et al, 1966;Mickelberry et al, 1966;and Marion et al, 1971). In general these fats have a similar fatty acid composition (Mecchi et al, 1956b;and Miller et al, 1962).…”

“…In general these fats have a similar fatty acid composition (Mecchi et al, 1956b;and Miller et al, 1962). Both fats are known for their degree of unsaturation (Hilditch et al, 1934;and Marion et al, 1971) and their low degree of stability (Mecchi et al, 1952(Mecchi et al, , 1956a.…”

Chemical characteristics of <i>solanum sisymbriifolium</i> lam seed oil and residual seed meal

“…Cabe destacar el elevado contenido en insaponificable total, si bien superior a lo determinado en otras especies de Solanum, dentro de valores encontrados en algunas Solaná-ceas (Dasso et al, 1980). El fósforo lipídico es equivalente a 0,38 % de fosfolípidos (factor de transformación 25; Marion et al, 1970).…”
