Virgin, refined and olive-pomace oils are separate products
Codex defines virgin olive oils as oils obtained from olive fruit solely by mechanical or other physical means under conditions that do not alter the oil. Refined olive oil is produced by refining virgin olive oils, while olive-pomace oil comes from olive pomace and remains a separate category. USDA also distinguishes U.S. Extra Virgin, Virgin, Lampante, Olive Oil, Refined Olive Oil and multiple olive-pomace grades. Atlas retains the exact product category and processing history before comparing grade, production, price or trade evidence.
