Pectin, a complex polysaccharide found abundantly in the cell walls of fruits and vegetables, plays a pivotal role in various food applications owing to its unique gelling, thickening and stabilizing properties. As consumer preferences lean towards natural and sustainable ingredients, the demand for pectin as a food additive has surged. This burgeoning interest has prompted a comprehensive exploration into both the extraction methods of pectin from its natural sources and its diverse technological applications in the food industry. The extraction process involves breaking down the plant cell wall to release the pectin. Traditional methods such as hot acid extraction have been widely used, but advances in technology have spurred the development of novel techniques like enzyme-assisted extraction and microwave-assisted extraction. These methods aim not only to enhance the yield and purity of extracted pectin but also to minimize environmental impact and energy consumption. Pectin's versatility has positioned it as a valuable ingredient in the food industry. Its ability to form gels under specific conditions makes it a key component in the production of jams, jellies and fruit preserves. Additionally, pectin acts as a stabilizer in dairy products, prevents syneresis in baked goods and improves the texture of confectionery items. The application of pectin goes beyond its role as a gelling agent; it is also employed in the encapsulation of bioactive compounds, enhancing the functional properties of various food products. © 2024 Society of Chemical Industry.
果胶是一种广泛存在于水果和蔬菜细胞壁中的复杂多糖,由于其独特的胶凝、增稠和稳定特性,在各种食品应用中起着关键作用。随着消费者对天然和可持续成分的偏好,果胶作为食品添加剂的需求激增。这种新兴的兴趣促使人们对从天然来源提取果胶的方法及其在食品工业中的多样化技术应用进行了全面探索。提取过程涉及破坏植物细胞壁以释放果胶。传统的方法,如热酸提取,已经被广泛应用,但技术的进步推动了酶辅助提取和微波辅助提取等新技术的发展。这些方法不仅旨在提高提取果胶的产量和纯度,还旨在最小化环境影响和能源消耗。果胶的多功能性使其成为食品工业中一种有价值的成分。它在特定条件下形成凝胶的能力使其成为果酱、果冻和水果保存品生产的关键成分。此外,果胶还可用作乳制品的稳定剂,防止烘焙食品的脱水收缩,并改善糖果制品的质地。果胶的应用不仅限于其胶凝剂的作用;它还用于生物活性化合物的包封,增强各种食品产品的功能性。版权所有 2024 化学工业协会。
