Detection of Pectin in Plant Tissues

Pectin is an important polysaccharide present in the middle lamella and primary cell walls. Pectin, cellulose, hemi-cellulose and protein are the main polymetric composition of cell walls. Pectin has an effect on the cell wall properties, such as firmness, elasticity, plasticity, porosity, surface charge, pH, ion balance and so on. Besides, compared with cellulose and hemicellulose, pectin has stronger moisturizing properties and is also an important moisturizing component in the cell wall. The pectin content is different among plants, within a plant over time, and in various parts of a plant.

Pectin plays an important role in plant growth and morphological development, and activates plant defense response. It is also widely used as gelling, stabilizing and thickening agent in a variety of foods such as jam, drinks, and ice cream. Furthermore, pectin is proved to have multiple health promoting functions.

The determination and analysis of the species and content of pectin in plant samples can help to understand the positive role of pectin in plant growth, morphological development, plant defense, and biomedicine. STEMart is able to efficiently and accurately determine the content of pectin in plant tissues.
