Method for extracting medlar polysaccharide

Abstract

The invention discloses an extraction method of wolfberry polysaccharide, comprising the following steps: A picking wolfberry; B grinding the fresh wolfberry into homogeneous pulp using a pulp grinder; C pouring the homogeneous pulp into a container; D microwave processing the homogeneous pulp to 50-100 centigrade and boiling the homogeneous pulp for 10-60 minute; E stopping the microwave processing and adding the purified water into the boiled pulp and continuously stirring up the pulp until the temperature is reduced to 50-80 centigrade; F inserting an ultrasonic rod to perform ultrasonic treatment for 20-90 minute; G processing the pulp being subjected to ultrasonic treatment using an industry centrifuges at 3000-5000 r and spilling out the supernatant and decompression concentrating H at 60-90 degree and adding alcohol until the final alcohol concentration is 80-90% and separating and precipitating the mixture using the industry centrifuges at 3000-5000 r to obtain the polysaccharide raw powder or coarse paste. The extraction method has features of high efficiency, energy saving and quick extraction speed. The extraction method solves the problem that the work for drying the wolfberry is heavy and the energy source is waste in Northwest China in harvest season and the extraction technology of the wolfberry polysaccharide is increased and the wolfberry polysaccharide yield is increased.

Description

technical field [0001] The invention relates to the extraction of polysaccharides from fresh wolfberry fruit, and the technical fields of microwave and ultrasonic waves. More specifically, it relates to a high-efficiency and energy-saving extraction method of wolfberry polysaccharides, which is especially suitable for directly processing wolfberry fruits in Ningxia wolfberry harvest season without drying or drying, saving manpower, material resources and energy, and at the same time, the rapid extraction process also improves production enterprises. extraction efficiency. Background technique [0002] Ningxia wolfberry is a traditional Chinese herbal medicine in my country. "Compendium of Materia Medica" records: "Nourishing liver and kidney, benefiting essence and eyesight". "Compendium of Materia Medica" states: "Goji berry can replenish qi, nourish blood, generate yang, grow yin, and dispel rheumatism. It has a wonderful effect." Traditional Chinese medicine in the pas...

Problems solved by technology

[0003] On the one hand, the present invention is based on the problem urgently needed to be solved in the production practice of Chinese wolfberry in Ningxia, Northwest my country: the harvested wolfberry cannot be dried in time on rainy days, resulting in a large number of moldy wolfberry. The quality and safety of goji berries; in order to dry goji berries in time, many farmers adopt the method of baking, but the current annual output of goji berries in Northwest China is 200,000-300,000 tons, and baking wastes a lot of coal resources

However, the existing microwave and ultrasonic extraction devices do not involve the extraction of active ingredients from fresh biological materials and the ultrafine pulverization function of microwaves.
