Which fruit juice brand was founded in 1947 in Florida?

The fruit juice brand founded in Florida in 1947 was Tropicana.

Italian immigrant Anthony T. Rossi established the business in the Bradenton-area citrus industry. Its early operations included packing fruit gift boxes and preparing fruit segments for salads under the name Manatee River Packing Company. The company later expanded into orange juice and adopted the Tropicana name as the brand grew.

A major turning point came in 1954, when Rossi developed a flash-pasteurization process designed to preserve the flavor of chilled, non-concentrated juice. Tropicana Pure Premium became the company’s signature product, helping make refrigerated orange juice a widely distributed supermarket staple.

Welch’s is best known for grape products, Ocean Spray is a grower-owned cooperative associated with cranberry drinks, and Minute Maid is a separate juice brand launched by the Vacuum Foods Corporation. They are plausible beverage answers, but none matches the 1947 Florida founding described here.
