Apa Itu Pectin Lyase? Aplikasi, Dosis, Alternatif & Spesifikasi

Pectin is a natural high-molecular-weight water-soluble polysaccharide extracted from the cell walls of plants. It is an important category of plant-derived hydrophilic colloids, and is one of the most widely used gelling agents and thickeners in the global food industry. Its INS number is 440, EU E number is E440, and CAS number is 9000–69–5. In terms of chemical structure, pectin is an anionic high-molecular-weight polysaccharide composed mainly of α-1,4-linked D-galacturonic acid units. Part of the carboxyl groups are methyl esterified, while others exist as free carboxyl groups or their calcium/sodium salts. The degree of esterification (DE) is a key parameter for determining the gelling properties of pectin. Based on the degree of esterification, pectin is mainly divided into two types: High Methoxyl Pectin and Low Methoxyl Pectin. From the source point of view, commercial pectin is mainly extracted from citrus peel, apple pomace, lemon peel, and other fruit peels or pomace. Citrus peel is one of the highest-quality sources of pectin, and apple pomace is also an important extraction raw material, together accounting for approximately 72% of global pectin production. Pectin appears as a white to light yellow-brown powder, odorless, stable in acidic solutions, and more easily degraded in alkaline environments. There is a fundamental difference in the gelling mechanism and conditions between HM and LM pectin. HM pectin requires soluble solids ≥60% and pH 2.6–3.4 to form an irreversible gel, whereas LM pectin requires the presence of divalent cations such as calcium or magnesium to form a gel, with lower requirements for sugar and acid.

Pectin is recognized as a natural fruit-derived gelling agent and is the most widely used hydrophilic colloid in the food industry, holding a foundational position in modern food processing, pharmaceutical health, and daily chemical products. Its most outstanding core advantages lie in its pure plant origin, flexible and tailorable gelling properties, and extremely wide application adaptability.

Pure Plant-Derived Natural Attribute: Pectin is a natural plant-derived colloid extracted from sources such as citrus peel and apple pomace, perfectly aligning with consumer demand for clean-label, plant-based, and non-GMO ingredients. The global expansion of the plant-based food and clean-label market creates strong momentum for pectin adoption.
