Another little known trick food producers use to protect their sales without regard to how it affects the buyer.

White blush discolorization is unsightly and unappetizing. As a result, consumers invariably associate white blush with distastefully old carrots, even though the taste and nutritional value of processed carrots are not affected by the appearance of white blush. This fact leads to significant commercial waste when processed carrots are pulled from the shelf due to the appearance of white blush even though taste and nutrition are not being effected.
