The study was aimed at determining the level of cis9trans11 C18:2 acid (CLA) and trans C18:1 and C18:2 isomers in fat of hard, mould and processed cheeses as well as that of fermented drinks: yoghurts, kefirs and acidophilous milk. Fatty acid composition of the fat of the products examined was assayed with the method of gas chromatography on a 100 m capillary column with a CP Sil 88 phase. Investigations...
The fatty acid composition of milk fat during a year was determined by gas chromatography with the use of a 100-m capillary column with high-polar liquid phase. The experimental material were samples of fat isolated with the extraction method from 30% non-pasteurised cream. The study demonstrated that the range of changes in the content of trans isomers of milk fat over a year was significantly higher...
The fatty acid composition of milk from Lowland Black-and-White and Polish Red cows was determined for the period of pasture feeding. The total fatty acid profile was determined by gas chromatography with a 50 m long polar capillary CP Sil 88 column. The content of trans C18:1 acid was determined with the same column after separating first the fraction of trans monoenoic methyl esters by silver-ion...
The trans fatty acids in milk fat from the indoor feeding ( March, April) and the pasture feeding period (May) were determined. An argentation thin layer chromatography (Ag-TLC) and gas liquid chromatography (GLC) on a polar capillary column (CP Sil 88) were used.The content of trans fatty acids in milk fat showed considerable seasonal variations. The trans 18:1 content for the pasture period was...
Применяя метод газовой хроматографии для разделения гексановых экстрактов, содержащих хлорированные углеводороды, определяли содержание DDT, DDE, DDD и γ-НСН в молочном жиру, выделенном из масла, изготовленного в 1983—1984 гг. в Олыптыньском воеводстве. Исследовали масло из маслозаводов в Бартошице, Езёраны, Корше, Мронгове, Пасленке и Щитно. Отметили наличке всех определяемых соединений в разных...
