Citrus pectin polysaccharide extracting method

Abstract

The invention provides a citrus pectin polysaccharide extracting method which comprises the steps of raw material smashing treatment, ultrasonic extraction and polysaccharide content determination. In a high-power energy-gathering ultrasonic mode, a high-strength ultrasonic field directly acts on extract raw materials, the ultrasonic energy utilization rate is high, uniform material smashing is ensured, local excessive crushing is decreased, and the cavitation effect of ultrasonic waves, mechanical effect, heat effect and other effects on the aspects of cell disruption, mass transfer promotion, reaction acceleration and the like are fully played. The method has the advantages that the extracting temperature is low, the time is short, the energy consumption is small, the extracting rate is high, effective ingredients are not easily damaged, the automation degree is high, a structure is compact, a split movable design is adopted, the occupied area is small, and citrus pectin polysaccharide is convenient to use and safe and the like. The shortcomings of a traditional extracting method are broken through, an energy-gathering ultrasonic reinforcing solvent is adopted to extract the citrus pectin polysaccharide, the optimal technological conditions are optimized through response surface design, and technological reference is provided for protection and comprehensive utilization of citrus peel resources.

Description

technical field [0001] The invention relates to a method for extracting citrus pectin polysaccharides, belonging to the technical field of sugar extraction. Background technique [0002] Citrus peel (Pericarpium Citri Reticulatae), also known as tangerine peel, is the dry and mature peel of Rutaceae plant orange (Citrus Reticulata Blanco). . According to reports, citrus peel has pharmacological activities such as cardiotonic, anti-shock, anti-tumor, anti-oxidation, soothing liver and gallbladder. Citrus is the fruit with the largest production volume, trade volume and processing volume. It is cultivated in many countries and regions. According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), the world's citrus cultivation area has reached 7.8 million m2 in recent years, with a total output of 1- 400 million tons. Citrus peels account for about 20% to 40% of the weight of the fruit, and the peels are often treated as waste, which wast...
