Worked Solution & Example Answer:State the role of each of the following in relation to the processing of cheese - Leaving Cert Home Economics - Question 5 - 2010
Step 1
lactic acid bacteria
Answer
Lactic acid bacteria play a crucial role in cheese processing by acting as a starter culture. They facilitate the fermentation process by converting lactose into lactic acid. This increase in acidity not only helps in the development of flavor but also serves as a preservative, inhibiting the growth of undesirable microorganisms in the cheese.
Step 2
rennet
Answer
Rennet contains enzymes that are pivotal in the cheese-making process, especially in coagulating the milk protein caseinogen into curds. The action of rennet leads to the formation of a gel-like structure, which separates the curds from the whey, forming the basis for cheese production.
