General description

Rennet, an enzyme extract is mainly used in the dairy industry. Chymosin is the main constituent of rennet. In commercial preparation of rennet, other proteases like bovine pepsin is also present in varying concentrations.

Application

Rennet from Mucor miehei has been used:
  • for milk coagulation trials
  • to coagulate the untreated milk and patatin treated milk
  • to coagulate the defatted samples of mammary secretions

Studies have shown that heat treatment of milk causes an increase in the rennet-induced coagulation times. This time was proportional to the temperature of the heat treatment.

Physical form

Powder containing maltodextrin and sodium chloride
