Quizplus · Accepted Answer

Sulphites are primarily used as preservatives to prevent oxidation and spoilage in foods and beverages, to maintain food color, and to prolong shelf life.

However, improving flavor is not a direct feature of sulphites; their main roles are preservation and prevention of discoloration.
