To determine the amount of milk needed to obtain the desired amount of lactic acid, we need to calculate the amount of lactose present in the milk.
Given that the milk has 48.5 g of lactose per kilogram of milk, we can calculate the lactose content in 2000 kg of milk.
Lactose content in 2000 kg of milk = 48.5 g/kg * 2000 kg = 97,000 g = 97 kg
Since lactose is transformed into lactic acid, the amount of lactic acid produced will be equal to the amount of lactose present in the milk.
Therefore, the amount of milk needed to obtain 2000 kg/h of yogurt with a concentration of 0.8% lactic acid is 97 kg.
It is necessary to make 2000 kg / h of yogurt whose concentration of lactic acid (C3H6O3) is 0.8%.
The reactions that account for the process are the following:
C12H22O11 + H2O -----> C6H12O6
C6H12O6 + Microorganisms -----> C3 H6O3
Determine the amount of milk to obtain this acidity if we start with milk that has 48.5 g of lactose per kilogram of milk, assuming that all the lactose is transformed into lactic acid.
