RENNET STRENGTH 213 



Time between addition of rennet and coagulation 

 = 6 minutes, or 360 seconds. 



I CO. rennet solution contains—^ = -05 grams (or cc.) 



of rennet. 

 Now -05 gram rennet in 360 seconds coagulate 



100 cc. milk, 

 therefore i gram rennet in 40 x 60 seconds coagulate 



100 X I X 40x60 



•05 X 360 ^'^^^ 



The rennet strength in this case is, therefore, 13,333. 



Rennet solutions may possess strengths up to 10,000, while 

 rennet powder may attain a value of 300,000. The reaction being 

 a catalytic one, a small proportion of rennet may theoretically 

 coagulate an infinite volume of milk.
