Corn

Corn, also known as maize, is a cereal grain that originated in Mexico. It is a staple crop grown worldwide, harvested when mature and typically dried. The kernels can then be processed in various ways, such as milling into flour or starch, or used whole.

Corn and its derivatives, such as corn starch and corn syrup, are widely used in the food industry. Corn starch acts as a thickener in sauces and desserts, while corn syrup is a common sweetener in confectionery and baked goods. Whole corn kernels are also used as a vegetable in many dishes.

Corn itself is not a food additive and does not have an E-number. It is a source of carbohydrates, fibre, and some vitamins and minerals. Whole grain corn provides beneficial fibre, while refined corn products like corn syrup are primarily sources of sugar. The NHS Eatwell Guide recommends that starchy carbohydrates should form the basis of most meals, and that free sugars should be limited.
