Which term describes the addition of nutrients back into food?

The term that describes the addition of nutrients back into food is enrichment. Enrichment specifically refers to the process of adding vitamins and minerals back to food items that may have lost these nutrients during processing. For example, white flour is often enriched with thiamin, riboflavin, niacin, folic acid, and iron to restore some of the nutrients that are lost when whole grains are milled.

In contrast, fortification involves adding nutrients to foods that do not naturally contain them. Preservation generally refers to methods used to keep food safe and prevent spoilage, whereas modification can mean altering the food in various ways but does not specifically indicate the addition of nutrients. Understanding these distinctions is important in the context of nutrition and food science.
