Which of the following is classified as an IQF fruit?

The correct answer is blueberries. IQF stands for Individually Quick Frozen, which is a freezing process designed to preserve the quality and texture of fruits. This method allows each piece of fruit to freeze separately, preventing them from clumping together while still maintaining their flavor, nutritional value, and original appearance.

Blueberries are often processed as IQF fruit because they are delicate and can easily become mushy if not frozen quickly. The IQF method helps retain their firm texture and makes it easy to use them in various dishes, from smoothies to baked goods, without the risk of them losing their structural integrity.

While raspberries, strawberries, and mangoes can also be found in IQF form, the emphasis here is on blueberries as the most commonly recognized example of IQF fruit in many product lines and recipes. Therefore, when considering the categories of IQF fruits, blueberries serve as a representative choice in this context.
