Abstract

The invention belongs to the technical field of pectin extraction, and provides a method for extracting pectin from green sunflower plates by salt. The green sunflower plates are used as raw materials, enzyme deactivation is performed in a water bath kettle in constant temperature, filtering is conducted, and an enzyme-deactivated solution is removed; distilled water is added to sediment, ammoniumoxalate or sodium citrate is added for extraction, filtering is performed, filtrate is subjected to decompression and rotary distillation, and concentrated sunflower plate extract is obtained after concentration, the concentrated solution is precipitated by ethanol, still stands and then is filtered to obtain pectin, the pectin is washed once or twice with anhydrous ethanol for dehydration, thenpasses through a 60-mesh sieve, naturally dried or dried at 40 degree or below, and crushed to obtain pectin powder. The method for extracting the pectin has high pectin extraction rate, the product is attractive without decolorization treatment, the material-liquid ratio is small, and the use amount of solvents and salt is significantly reduced, the utilization ratio of the sunflower plate is effectively improved, waste utilization is achieved, and the added value of the sunflower industry is increased.

Description

Technical field

[0001] The invention belongs to the technical field of pectin extraction technology, and specifically relates to a method for extracting pectin from sunflower green plates by using salt. Background technique

[0002] The sunflower planting area in my country is extensive, and a large number of sunflower trays are discarded, causing environmental pollution and waste of resources. Sunflower plate contains 15-25% pectin, which is rich in resources and cheap and easy to get. Therefore, it is of social and economic significance to vigorously develop my country's abundant sunflower disk resources and increase its utilization rate. Sunflower pectin is a natural polymer with unique molecular structure, biological activity and functionality, and its discovery has been a research hotspot in the chemical, pharmaceutical and food fields. A lot of research work is devoted to improving quality and increasing yield, but nearly 20-30% of pectin is inevitably degraded and lost d...
