Great. I "kinda" thought that was the case. So, you read the label on a bottle of chile sauce and it says "refrigerate after opening," but you decide not to do that, and leave the sauce out for a few days. The preservatives wouldthen help to keep the sauce fresh But, if the sauce were refrigerated as suggested by the manufacturer, there'd be no need for the preservatives. Is that a fair assessment?
Also, what about the use of plastic containers ... are they permeable and can air find its way into a fresh, unopenrd bottle over time? Would a preservative be helpful in that instance?
