果胶存在于植物的细胞壁和细胞内层，是植物细胞的重要组成部分，属于碳水化合物的衍生物，广泛分布于植物果实、根茎和叶中。 本试剂盒采用咔唑比色法测定总果胶含量。即总果胶在稀酸中水解为半乳糖醛酸，在硫酸溶液中与咔唑进行缩合反应，生成紫红色物质，经光谱扫描该物质在530nm处有最大吸收峰，颜色深浅与总果胶含量成正比，进而得出总果胶含量。
Pectin is present in the cell walls and intercellular layers of plants. It is an important component of plant cells, belonging to carbohydrate derivatives, and is widely distributed in plant fruits, roots, stems, and leaves. This kit employs the carbazole colorimetric method for determining total pectin content. Specifically, total pectin is hydrolyzed into galacturonic acid in dilute acid. In a sulfuric acid solution, the galacturonic acid undergoes a condensation reaction with carbazole to form a purple-red substance. Spectral scanning shows that this substance has a maximum absorption peak at 530 nm. The color intensity is directly proportional to the total pectin content, thereby allowing the calculation of the total pectin content.
