The article discusses the production, properties, and applications of pectin, pectinase, and protopectinase. Pectin is a type of plant-based polysaccharide that gives fruits their soft texture. The traditional pectin production process involves acid extraction, purification, and drying, but it has drawbacks. Researchers are exploring a new method using specific enzymes to improve pectin production. Protopectinase is an enzyme that breaks down protopectin into soluble pectin, which is important for various applications.
