Question 4 1 pts What does fermentation do to milk? O Fermentation produces lactic acid which acidifies the milk resulting in casein micelles losing their negative charge, falling apart, and coagulating into curds. Fermentation produces lactose whicha their negative charge, falling apart, and coagulating into curds. O Fermentation produces lactic acid which acidifies the milk resulting in whey micelles losing their negative charge, falling apart, and coagulating into curds. Fermentation produces lactic acid which acidifies the milk resulting in casein micelles losing their positive charge, falling apart, and coagulating into curds. Question 5 2 pts When making cheese, if you used a large amount of acid but very little rennet, what kind of cheese do you expect you would make?

Explanation / Answer

Ans 4.

(a) fermentation produces lactic acid which acidifies the milk resulting in casein micelles losing their negative charge, falling apart, and coagulating into curds.

Explaination:- The process of fermentation of milk involves the addition of lactic acid producing microorganisms these microorganisms consume the lactose present in the milk and thus they release lactic acid. Normally milk has a pH of 6.6 and the casein proteins have a negative charge but once lactic acid is produced by these microorganisms the pH decreases and the negative charge of casein is neutralised thus they fall apart and results in curd formation.
