A very important point of pectin is the relative molecular mass of pectin. You may not know this well. As a manufacturer of pectin, we will introduce the relative molecular mass of manufacturer pectin for blueberry jam.
The relative molecular mass of manufacturer pectin for blueberry jam
First, the relative molecular mass of pectin is between 50 and 300 ku. And then, the relative molecular masses of pectin extracted from different raw materials and processes vary greatly. Gel method and High Performance Size Exclusion Chromatography (HPSEC) are the main methods to determine the relative molecular mass of pectin. The HPSEC determination is more accurate, and the results have a large amount of information. Furthermore, the HPSEC method can determine the weight-average molecular weight (Mw) and number-average molecular weight (Mn) of pectin. The polydispersity Mw/Mn characterizes the distribution width of molecular mass. Moreover, the larger the Mw/Mn, the wider the molecular mass distribution. On the contrary, the molecular mass distribution range is narrower.
At present, the relative molecular mass is widely used to connect HPSEC with Multi-angle Laser Light Scattering (MALLS) and Refractive Index Detection (RI) in series to characterize the absolute molecular mass of pectin. The advantage of the HPSEC-MALLS-RI combination technology is that the absolute molecular mass of each point in the sample map can be directly measured through the data of the MALLS and RI detectors, without any column calibration and standard reference. This method is particularly suitable for the determination of pectin macromolecular structure for which it is difficult to obtain standard products.
Therefore, the relative molecular mass of the pectin manufactured by us is in full compliance with the requirements. You can trust the quality of our company’s products.
