Carrageenan is a food-grade additive derived from certain types of red seaweed. Widely used in the food industry for its gelling, thickening, and stabilizing properties, carrageenan is particularly known for its application in dairy and plant-based products. As a natural hydrocolloid, carrageenan undergoes careful processing to meet food-grade standards, ensuring its safety and efficacy. It is commonly employed in products like ice cream, yogurt, and plant-based milk alternatives to enhance texture, prevent ingredient separation, and create a smooth, appealing consistency. Despite its extensive use, carrageenan has been a subject of occasional debate regarding its safety, and various forms, such as degraded carrageenan, have been studied for their potential health implications. As research continues, the food industry remains attentive to consumer concerns, exploring alternative stabilizers while utilizing carrageenan within established safety guidelines.
