Pasteurization of milk is a process

by gmatdriller » Sat Jul 09, 2011 5:06 pm
Pasteurization of milk is a process by which milk is heated to a certain temperature and then rapidly cooled, killing pathogens and increasing the milk's shelf life. Recently pasteurization has come under fire because it has been found that during pasteurization many helpful digestive enzymes are destroyed, and many dangerous pathogens, including the MAP bacterial strain, which is linked to Crohn's disease, are not. Because of this, some people have started drinking 'raw milk' milk, which is not pasteurized or otherwise processed. Proponents of pasteurization point out that that pasteurization is still necessary to reduce bacterial contamination, and that heating milk at home also kills beneficial digestive enzymes. Raw milk drinkers argue that this argument is beside the point, since most people who drink milk do not heat it first, or else misleading, since ___________________.

A: Many of the proponents of pasteurization are dairy farmers who rely on the increased shelf life of pasteurized milk to ship their product farther away

B: It is clear that killing pathogens that may be present in milk is not the only effect of pasteurization.

C: Cooked milk is generally heated to a higher temperature than pasteurized milk is.

D: milk that is subjected to both processes loses even more of the helpful digestive enzymes than milk subjected to either process alone.

E: Pasteurization serves to ensure a longer shelf life for milk, while heating milk is usually the final step in its preparation.

Explanations please! OA after some discussions.

IMO: D

First claim: Pasteurization is required to kill harmful bacteria, even heating also kills helpful enzyme.
Second claim: Aha!! - No : since most people who drink milk do not heat it first, or else misleading, since ___________________.

So we need to look for a reason why the first claim is misleading?

A: Many of the proponents of pasteurization are dairy farmers who rely on the increased shelf life of pasteurized milk to ship their product farther away ( Attack on people, INCORRECT )

B: It is clear that killing pathogens that may be present in milk is not the only effect of pasteurization. ( CONTENDER )

C: Cooked milk is generally heated to a higher temperature than pasteurized milk is. ( IRRELEVANT)

D: milk that is subjected to both processes loses even more of the helpful digestive enzymes than milk subjected to either process alone. ( CONTENDER)

E: Pasteurization serves to ensure a longer shelf life for milk, while heating milk is usually the final step in its preparation. ( IRRELEVANT )

D looks more promising, because it disapprove the first claim by showing compound effect of heating process.

I rephrased as follows:

Pasteurization (heating & cooling): has say 50 bad effects.

Proponents of pasteurization advised THAT
drinkers of raw milk pasteurize

AND THAT
heating raw milk also has equally bad effects

Drinkers of raw milk: say that argument is off track, or misleading since.........

Sure, if drinkers of raw milk do not undergo the process of heating, they could simply
obviate the bad effects of heating. If, on the other hand, they have to (i) heat AND
(ii) pasteurize, resulting to safer milk, we can say that combining both process is
an added benefit.

Option D suggests that combining both processes causes more harm than good..
My question is this: From the passage, proponents of pasteurization did not say
both processes be combined; so, how did option D arrive at such position?.
