Apple Pectin is a complex heteropolysaccharide composed predominantly of partially methylated poly-alpha-1,4-D-galacturonic acid. It is commercially extracted from apple pomace — a byproduct of juice production — using hot dilute acid extraction followed by purification and precipitation with alcohol or aluminum salts.
Available in both high-methoxyl (HM, >50% DE) and low-methoxyl (LM, <50% DE) grades, apple pectin gels under specific sugar/acid or calcium conditions respectively. Classified as E440 and holding GRAS status, it is valued for its lighter color, milder taste, and excellent clarity compared to citrus-derived pectin. It is widely specified for premium jams, fruit preparations, and confectionery where color and taste neutrality are paramount.
