Table of content
• How healthy is rapeseed oil ?
• Rapeseed oil in food
• Biodiesel and heath
Saturated fatty acids
• 6 % in rapeseed
• 7-8 % of the daily energy feed charge
• Not as healthy as unsaturated fatty acids
• Cannot be used by the body
Unsaturated fatty acids
• 66 % in rapeseed
• 12-13 % of the daily energy charge
• Very healthy
• Used by the body
Polyunsaturated fatty acids
• 27 % in rapeseed
• 7- 8 %
• Very healthy –> cannot be synthesized by the body
• Omega-6 fatty acid and Omega3 fatty acid 2 : 1 rate in a rapeseed
Nutrition
• Different types of oil
• Use in dishes
Types of oil
• Pressing - central oil mill (hot pressed, more oil) - decentral oil mill (cold pressed, less oil)
• Extraction
Rapeseed oil in food
• Virgin oil has the best aroma and is the healthiest
• Fine oil has a neutral taste and has a wide variety of use
Cold and warm dishes/cake
• Virgin oil for cold dishes (like salads or dips)
• Fine oil for cooking
• Fine oil for baking (neutral taste and soft fats)
Frying and marinating
Frying :- Fine oil (heat resistant)
Marinating :- Virgin oil (better taste)- Marinating and frying is better with the more
heat resistant fine oil
Health and biodiesel
• Cholesterol
• More clever babies
• Biodiesel
Cholesterol
• HDL healthy LDL unhealthy• Rapeseed oil has a higher quality against
cholesterol than olive oil; no omega3 fatty acids• Native oil drops the LDL level due to the
phytosterol in the rapeseed• Fish, soy and lecithin drop the LDL level• Sport and outdoor activities increase the
amount of HDL
More clever babies
• Omega-3 fatty acids• Have positive effects on the mental
development of newborns• Omega-3 fatty acids prevent from heart
diseases• Are contained in rapeseed oil, walnut oil,
salmon, anchovies and other fat sea fish
Biodiesel
• Lower the risk of premature deaths and cancer
• Environmental friendly cultivation of rape
• Less asthmatic people due to the decrease of airborne particles with the combusting of biodiesel
