English to Spanish Other Food & Drink

En una lista interminable de productos, aparece:

"Dried and Dehydrated Fruits, Vegetables and Soup Mixes

Establishments primarily engaged in sun drying or artificially dehydrating (including freeze drying) fruits and vegetables, or in manufacturing packaged soup dry mixes from dehydrated ingredients. Products include dates; dehydrated fruits, vegetable and soups; dried olives; fruit flour, meal and powders; noodle mixes; olives, dried; potato flakes, granules and other dehydrated potato products; prunes; raisins; rice, uncooked: packaged with other ingredients; salad dressing and sauce mixes, dry; soup mixes and powders; **sulfured fruits and vegetables**; vegetable flour, meal and powders; etc."

To sulfur se traduce sulfurar o azufrar [wordmagic], pero no logro encontrar ninguna referencia que me permita corroborar sulfurado o azufrado en este contexto.

¿Alguien sabe de qué se trata? Muchísimas gracias
