Q. Some orange juice is labeled ''not from concentrate.'' Wouldn't that be fresh squeezed?
A. Orange juice labeled ''not from concentrate'' is flash-heated to pasteurize it immediately after the fruit is squeezed. It has never been concentrated, according to the Florida Department of Citrus guide to juice labeling.
''Fresh squeezed'' juice has not been pasteurized, according to the guidelines.
As for other orange juice designations, ''chilled'' or ''ready-to-serve'' is juice made from frozen concentrate or pasteurized juice, and ''fresh frozen'' is freshly squeezed juice packaged and frozen without pasteurizing or further processing.
Fresh-frozen orange juice is usually sold in a market's frozen food section and is ready to drink after it thaws.
