In rat and some other species a diet with a high caloric per cent of rapeseed oil induces the rapid accumulation in their heart muscles of fat droplets, consisting mainly of triglycerides [ 1, 21. Macroscopically the hearts grow pale and the contractile force of the heart muscles decreases markedly after 2-3 days, The adverse effect of rapeseed oil is mainly caused by erucic acid (cis13-docosen...

Pennycress (Thlaspi arvense L.), a plant naturalized to North America, accumulates high levels of erucic acid in its seeds, which makes it a promising biodiesel and industrial crop. The main carbon sinks in pennycress embryos were found to be proteins, fatty acids, and cell wall, which respectively represented 38.5, 33.2, and 27.0% of the biomass at 21 days after pollination. Erucic acid reache...

In Sri Lanka, mustard (Brassica juncea) is cultivated as a subsidiary crop for the seeds used as a condiment in cooking. In the Indian sub-continent, however, it is an important oilseed crop used as a source of vegetable oil. Mustard has over 45% erucic acid (C22:1) which is unsuitable nutritionally for human consumption. The Brassica oilseed species, B. napus and B. campestris, were developed ...

Edible oil is an important element in the diet of most transitional countries; nevertheless, little is known about the fatty acid composition of these oils. We examined the consumption of edible oils and the fatty acid composition of these oils obtained from a market survey conducted in seven Chinese provinces and in Beijing. Three days of measured household food intake from the 1997 China Heal...

Background: Utilization of energy-dense lipid fuels is critical to the rapid development and growth of neonates. Objective: To increase efficiency of milk fat utilization by newborn pigs, the effect of clofibrate on in vivo and in vitro longchain fatty acid (LCFA) oxidation was evaluated. Methods: Newborn male pigs were administered 5 mL of vehicle (2% Tween 80) with or without clofibrate (75 m...

Canola is an offspring of rapeseed (Brassica napus and Brassica campestris/rapa), which was bred through standard plant breeding techniques to have low levels of erucic acid and glucosinolates. Canola seed is rich in oil, and after oil extraction, the remaining “canola meal” (CM), is a rich protein source used as feedstock to different animal species, mainly dairy cows in North America and in E...

In a previous communication it was reported that feeding rape oil to rats for a month as 25 per cent by weight of their diet caused a 3to 4-fold increase in the amount of cholesterol in their adrenals (1). A similar effect has been obtained by feeding large amounts of turnip seed oil, nasturtium seed oil, or a weed seed oil obtained chiefly from species of Brassica. Other fats and oils have gen...
