Method for efficiently extracting pectin by taking sunflower disc as raw material and application of pectin

The invention is applied to the technical field of pectin extraction, and discloses a method for efficiently extracting pectin by taking sunflower discs as a raw material, and the extraction process of the method comprises the following steps: feeding, pumping, heating, collecting, filter pressing, concentrating, drying, crushing and extracting. According to the method for efficiently extracting the pectin by taking the sunflower disc as the raw material, the sunflower disc is subjected to low-temperature steam infiltration cooking in a low-pressure environment, so that the pectin in the sunflower disc can be continuously separated out along with the falling of distilled water, and the stable separation of the pectin is ensured by the low-temperature long-time cooking mode; meanwhile, the property change of the pectin caused by high-temperature cooking is avoided, so that the separation difficulty of the method is reduced, the separated finished product is high in purity and light in color, the dried sunflowe
