Preserving
Fruit
After approx. 40 to 50 minutes, small bubbles begin to form at
short intervals. Switch off the oven.
After 25 to 35 minutes of residual heat, remove the preserving
jars from the cooking compartment. If they are allowed to cool
for longer in the cooking compartment, germs could multiply,
promoting acidification of the preserved fruit.
Vegetables
As soon as bubbles begin to form in the jars, set the
temperature back to between 120 and 140 °C. Depending on
the type of vegetable, heat for approx. 35 to 70 minutes. Switch
off the oven after this time and use the residual heat.
Taking out the jars
After preserving, remove the jars from the cooking
compartment.
Caution!
Do not place the hot jars on a cold or wet surface. They could
suddenly burst.
Acrylamide in foodstuffs
Acrylamide is mainly produced in grain and potato products
prepared at high temperatures, such as potato crisps, chips,
toast, bread rolls, bread or fine baked goods (biscuits,
gingerbread, cookies).

Beetroot approx. 35 minutes approx. 30 minutes
Brussels sprouts approx. 45 minutes approx. 30 minutes
Beans, kohlrabi, red cabbage approx. 60 minutes approx. 30 minutes

Tips for keeping acrylamide to a minimum when preparing food
General
■ Keep cooking times to a minimum.
■ Cook meals until they are golden brown, but not too dark.
■ Large, thick pieces of food contain less acrylamide.
Baking With top/bottom heating max. 200 °C.
With 3D hot air or hot air max.180 °C.
Biscuits With top/bottom heating max. 190 °C.
With 3D hot air or hot air max. 170 °C.
Egg or egg yolk reduces the production of acrylamide.
Oven chips Spread evenly over the baking tray, in a single layer. Bake at least 400 g per baking tray
so that the chips do not dry out
