General Product information

  • WalcoRen® Liquid Rennet Paste Dolce is a pure natural rennet paste which is based on the production of traditional rennet paste. It is produced exclusively from the fourth stomach of young calf’s through an extraction process which was especially developed in Tyrol/ Austria.
  • The balanced composition between Chymosin, Pepsin and Lipases results only on the natural processes in the calf’s stomachs.
  • A fault free system of control from the slaughter house to delivery of the finished product guarantees precise batch traceability.

  • The commercial concentration is set at 1:15.000 Soxhlet / 166 IMCU/ml.
  • WalcoRen® Liquid Rennet Paste Dolce is a brownish to yellow cloudy liquid with natural cheesy odour. Small colour differences between individual batches depend on the natural raw materials employed.

This rennet has been microbiologically analysed in accordance with the analysis regulations of the Swiss Dairy commission and it fulfils all the bacteriological demands.

Total viable plate count < 120.000/ml
Yeasts/moulds < 100/ml
Coliform bacteria < 30/ml
Salmonella negative in 25 ml
Listeria negative in 25 ml
Staphylococcus Aureus negative in 25 ml

The above bacteriological analysis details are valid only for correct storage at 0-8°C and for containers with their original seals.
  • SHAKE VERY WELL BEFORE USE – as this product tends to un-mix during storage it is necessary to shake well before each use to guarantee the ideal and unique mixture of all the enzymes.
  • WalcoRen® Liquid Rennet Paste Dolce is especially used for all flavoured soft, semi-hard and white – blue mould cheeses where calf-lipase is wanted for the development of the typical ripening flavours.
  • The dosage quantity is determined by the quantity of milk, the required process parameters and the enzyme concentration - pH, temperature, required coagulation time, pasteurised milk.
  • WalcoRen® Liquid Rennet Paste Dolce should be stirred into 15 to 30 times of the amount of chlorine free cold water and then be added to the milk. Because of its natural pureness WalcoRen® Liquid Rennet Paste Dolce does not need to be filtered and can therefore be directly added to the milk.

WalcoRen® Liquid Rennet Paste Dolce is a brownish to yellow cloudy liquid with natural cheesy odour and contains only approx. 20% table-salt (sodium chlorite) and max. 0,5% of Sodium-Benzoate and is therefore safe to utilise.
As with all natural enzymes, WalcoRen® Liquid Rennet Paste Dolce should be stored in a dark place at a temperature between 0°C and +8°C.
