Answer:
Agricultural products that are produced extremely long distances from the US can be sold in American markets today due to refrigeration and preservation.
Explanation:
Preservation refers to a process that preserves food for a longer period without spoiling. Preservation inhibits microbial activity and enzymatic activity, allowing food products to be marketed throughout the year, regardless of geographical location, which offsets local variations in production and seasonal differences in availability.
The most common preservation methods are freezing, sugaring, drying, salting, lactic acid fermentation, smoking, acidification, vinegar preservation, sealing, heat treatment, irradiation, use of preservatives, pasteurization and UHT heating.
