One sachet instead of three single-purpose products in the cupboard
Kaiser Natron is pure sodium bicarbonate in powder form — the original from Bielefeld, for the kitchen, the house and the road.
🥄
One powder, many jobs
Baking, cooking, household tasks: the range is printed on the box itself — for kitchen, house and travel.
⚗️
Mildly alkaline
Dissolved in water, sodium bicarbonate turns slightly basic. That single property is what makes the powder so widely usable.
💎
One substance, nothing else
No anti-caking agent, no flavouring, no colouring. Each sachet holds sodium bicarbonate of food grade and nothing more.
📦
Portioned, not loose
An opened sachet stays manageable while the others remain sealed in the carton. No caked powder at the bottom of an open tin.
Sunday afternoon, the cake batter is ready in the bowl — and the baking powder tub is empty. Or the black tea tastes of the tap rather than of the leaf. In a lot of kitchens there is a green carton at the back of a cupboard for exactly these moments.
The chemistry is simple. Under heat, or on contact with an acid, the salt breaks down and releases carbon dioxide — and that gas is what lifts the dough. The same reaction runs when the powder meets fruit acid: the acid is bound and loses its edge. One substance, two effects, both resting on the same principle.
Behind the green box stands Arnold Holste Wwe. GmbH & Co. KG of Bielefeld, a family business whose roots go back to 1825. The recipe has not changed in that time because there was nothing to change: one substance, one sachet, one box. Anyone after more ideas will find them in the booklet that comes with every pack.

What does mildly alkaline mean?
Dissolve the powder in water and you get a weakly basic solution with a pH of around 8. Pure water sits at 7, a classic household lye well above 11. So the powder moves only just past the neutral point — strong enough to do something, mild enough to be permitted in food. That middle ground is the whole trick.
Bicarbonate, soda ash and baking powder — where is the difference?
Bicarbonate of soda is sodium bicarbonate, NaHCO₃. Baking powder is bicarbonate plus an acidifier and a carrier such as starch, so it brings its own acid along. Soda ash, by contrast, is sodium carbonate (Na₂CO₃), markedly more alkaline and intended for cleaning rather than for food. Mix the three up and you end up with either a flat cake or the wrong product in your batter.

💬 Frequently asked questions
-
What can I use the powder for in the kitchen?+
As a raising agent in baking, to soften the acidity of fruit and dishes, to soften water for tea and coffee, and to keep the colour when cooking vegetables. The enclosed booklet lists further uses around the house and on the road.
-
Can I use it instead of baking powder?+
Only when the batter contains an acid — buttermilk, yoghurt, lemon juice, honey or sharp fruit. That is what releases the gas which lifts the dough. Baking powder already carries its acid as an ingredient, so the swap does not work in every recipe.
-
Does it contain aluminium?+
No. Each sachet holds sodium bicarbonate (E 500 ii) only, a sodium salt of carbonic acid. Aluminium compounds are not part of the composition.
-
Is Kaiser Natron the same as baking soda or bicarbonate of soda?+
Yes. Baking soda, bicarbonate of soda, bicarb and the German Natron or Speisenatron all name the same substance: sodium bicarbonate. Only "baking powder" and "soda ash" mean something different.
-
Can you taste it in baked goods?+
Too much of it leaves a soapy note, especially when there is little acid in the batter. Stick to the amount in the recipe and the taste stays in the background.
-
Is it any use outside the kitchen?+
Yes, that is what it has been meant for over generations. Which uses the maker intends is set out in the Kaiser Natron booklet that comes with every pack.
