Apple juice – Germany’s sweetheart

With an annual per capita consumption of 6.8 litres, apple juice is one of the most popular juices in Germany. For the production of 1 litre of apple juice, approx. 1.5 kg of apples are needed. After pressing, the juice is naturally cloudy, i.e. with fruit flesh. By centrifuging and filtering the juice, it finally becomes clear. To preserve the juice, it is pasteurised. For this purpose, the apple juice is heated briefly to 78°C to kill microorganisms and germs.


Ethanol content in fruit juices


Ethanol can form even before the fruit is harvested. In Germany, an ethanol content of 3 grams per litre is permitted in fruit juices, which corresponds to about 0.38 % vol. Pasteurisation also ensures that an already started fermentation process (ethanol formation) is stopped.


Organic and conventional apple juice varieties


In terms of taste, it makes no great difference whether organic or conventional cultivation is used. However, if you take a closer look, up to four pesticides were found in all conventionally produced apple juice varieties. These were only present in trace amounts. Good news for producers and consumers: none of the tested varieties failed.

What must the apple juice taste like?


  • fruity
  • slightly acidic
  • fresh


Apple juice should have a good balance between acidity and sugar content. How an apple juice smells and tastes depends mainly on the apple varieties used, the production process and storage.
At bilacon GmbH there are professionally trained employees who examine your apple juice in the field of sensory.


Patulin in apple juice


Another important issue for apple juice is the patulin content.

Patulin is a mycotoxin, which occurs particularly in brown rotten apples and is harmful to health. Brown rot on fruit is caused by insects, weather and storage of the apples. Brown rot spots are a good breeding ground for patulin-forming fungi.

Patulin is classified as a nerve poison and can lead to gastrointestinal problems, including gastritis and liver damage.

To prevent this, the EU has adopted a regulation setting maximum levels for patulin

For example

  • Apple juice and apple spirits a maximum level of 50 µg/kg
  • Solid apple products, e.g. apple puree a maximum of 25 µg/kg
  • Products for infants and young children a maximum of 10 μg/kg
