Summary
McElligott flash pasteurizes its apple juice in response to bacterial infections traced to its juice. Flash pasteurization involves quickly heating it and immediately chilling it. Intensive pasteurization involves heating juice for an hour, and this method kills bacteria more than any other method. Intensive pasteurization destroys the original flavor. McElligott’s orange juices have not been linked to any infections and remain unpasteurized.
Strongly Supported Conclusions
McEligott’s apple juice is more likely to have bacteria than juice that undergoes intensive pasteurization.
A
McElligott’s citrus juices contain fewer infectious bacteria than do citrus juices produced by other companies.
This is unsupported because as far as we know, McElligott’s citrus juices may have a lot or a little bacteria. We don’t know how this compares to other juice companies.
B
McElligott’s apple juice is less likely to contain infectious bacteria than are McElligott’s citrus juices.
This is unsupported because even though the apple juice is flash pasteurized, we don’t know how much bacteria the citrus juice has to begin with. The citrus juices may already have no bacteria even without pasteurization.
C
McElligott’s citrus juices retain more of the juices’ original flavor than do any pasteurized citrus juices.
This is unsupported because the author never tells us how flash pasteurization affects flavor, meaning flash pasteurized citrus juices may have as much of the original flavor as McElligott’s.
D
The most effective method for eliminating bacteria from juice is also the method most likely to destroy flavor.
This is unsupported because while intensive pasteurization is the most effective method for eliminating bacteria from juice, we don’t compare its likelihood of destroying flavor to that of any other method.
E
Apple juice that undergoes intensive pasteurization is less likely than McElligott’s apple juice is to contain bacteria.
This is strongly supported because intensive pasteurization, which McElligott’s apple juice does not undergo, eliminates more bacteria than any other method of pasteurization.
