The phytotoxic effects and biodegradability of stored rapeseed oil and rapeseed oil methyl ester

No . 3458 Nutritional value of rapeseed oil

Comparison of the effects of rapeseed oil, olive oil and hydrogenated plant oil on postprandial lipids and fatty acid oxidation

Olive and rapeseed oil are both considered beneficial for lipid metabolism because of their high content of monounsaturated fatty acids. We compared postprandial lipid metabolism after test meals with these plant oils including hydrogenated plant oil as a reference. Subjects and Methods: Twenty normolipidemic subjects (age: 25.1±4.9 year, M±SEM, body mass index 21.5±0.6 kg/m) underwent three on...

Ruminal lipid balance and intestinal digestion by dairy cows fed calcium salts of rapeseed oil fatty acids or rapeseed oil.

The effects of supplemental calcium salts of rapeseed oil fatty acids (FA) and rapeseed oil on ruminal metabolism and apparent digestibility of lipids in the small intestine were studied using three multiparous Holstein x Friesian cows in a 3 x 3 Latin square design. Cows fitted with ruminal, duodenal, and ileal cannulas were fed restricted amounts of a control diet (C) containing 65% corn sila...

Ethanolysis of rapeseed oil − distribution of ethyl esters, glycerides and glycerol in ester and glycerol phase

The distribution of ethyl esters, triglycerides, diglycerides, monoglycerides and glycerol between the ester and glycerol phase was investigated after the ethanolysis of rapeseed oil at various reaction conditions. The determination of these substances in the ester and glycerol phases was carried out by the GC method. The amount of ethyl esters in the glycerol phase was unexpectedly high and th...

Milk performance of dairy cows supplemented with rapeseed oil, peanut oil and sunflower seed oil

The objective of the study was to investigate the effects of supplementing different plant oils to the basal diet on milk yield and milk composition in mid-lactating dairy cows. Forty Chinese Holstein dairy cows averaging 120 days in milk (DIM) at the start of the experiment (body weight = 580 ± 18.2 kg; milk yield = 33.0 ± 2.00 kg/day) were used in a completely randomized block design. The ani...
