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 enzymes.
  • WalcoRen® Liquid Rennet Paste Semi-Piccante is especially used for flavoured cheeses where sheep-lipase is wanted for the development of the typical ripening flavours. But also mixtures of milk or pure cow’s-milk will be very suitable in combination with WalcoRen® Liquid Rennet Paste Semi-Piccante.
  • 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 Semi-Piccante should be stirred into 10 to 20 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 Semi-Piccante does not need to be filtered and can therefore be directly added to the milk.

WalcoRen® Liquid Rennet Paste Semi-Piccante is a brownish to yellow cloudy liquid with natural cheesy odour and contains only approx. ≥18% 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 Semi-Piccante should be stored in a dark place at a temperature between 0°C and +8°C.
