• 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
