What term describes a product that has not undergone processing, freezing, or heating?

The term that describes a product that has not undergone processing, freezing, or heating is "fresh." Fresh products are typically in their natural state and have not been altered from their original form through preservation methods. This ensures that they maintain their original taste, texture, and nutritional value, which are highly valued in the culinary world and among health-conscious consumers.

In contrast, the other terms apply to products that have been processed or preserved. "Organic" refers to agricultural products produced without synthetic fertilizers or pesticides, and while they may be fresh, the term does not specifically indicate that they are unprocessed. "Frozen" indicates that the product has been subjected to low temperatures for storage, which means it is not fresh. "Preserved" implies that the product has been treated in some way, often through techniques like canning or pickling, to extend its shelf life, again moving away from the natural state that defines fresh products.
