Introduce the monosaccharide composition and content of manufacturer apple pectin for cherry jam
Due to factors such as the type of raw materials, growth period, harvest period, storage time and extraction method, the composition and physical and chemical properties of pectin are quite different. Therefore, the determination of the physical and chemical properties of pectin is of great significance to the characterization and quality determination of pectin.
Pectin is a form of heteropolysaccharide mainly composed of polygalacturonic acid. The Gal-A (galacturonic acid) content in commercial pectin is ≥65%. Then, we usually express the purity of pectin by the content of Gal-A. The determination of Gal-A content mostly adopts the carbazole sulfate method and the m-hydroxybiphenyl method, and the ion chromatography determination is more accurate. In addition, there are gravimetric, calcium pectinate titration and distillation titration. The composition of pectin monosaccharides varies greatly among different materials.
Monosaccharide composition can indirectly reflect the structure of pectin. Usually Gal-A (galacturonic acid) content is used to express the purity of pectin. Most of the neutral sugars of pectin are in its side chain, so Gal-A content is high. Pectin with low neutral sugar content indicates that there are fewer side chains in pectin. On the contrary, it shows that the content of side chains in pectin is higher. At present, the main methods for determining pectin monosaccharides include High Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection (HPAEC-PAD), Evaporative Light Scatter-ing Detector (ELSD) and Gas-Liquid Chromatography (GLC).
