Goji barbarum polysaccharide is a natural macromolecular substance with a variety of biological activities, which is widely used in medicine, health care products, food and other fields. The traditional method of extracting polysaccharides from wolfberry mainly uses hot water extraction, but the extraction time is long, the efficiency is low, and the purity of the extracted polysaccharides is not high. With the increasing application of ultrasonic technology in the extraction of natural products, the extraction of polysaccharides from wolfberry by ultrasonic technology has become a new research direction.
The principle of ultrasonic extraction of wolfberry polysaccharides is to use the vibration of ultrasound to break the cells inside the material, and the solvent penetrates into the cells to release the polysaccharide components in the cells. Compared with the traditional hot water extraction method, ultrasonic extraction has the advantages of short extraction time, high efficiency and high purity of polysaccharides.
In order to obtain the best ultrasonic extraction results, it is necessary to select the appropriate extraction conditions. Experiments show that the power of ultrasonics, extraction time, solid-liquid ratio and other factors have a significant impact on the extraction effect. Within a certain range, with the increase of ultrasonic power, the yield of polysaccharides gradually increased. However, when the power reaches a certain value, the polysaccharide yield will decrease. Therefore, choosing the right ultrasonic power is key. Extraction time and solid-liquid ratio also affect the yield of polysaccharides, and the optimal extraction conditions need to be determined experimentally.
In addition to ultrasonic technology, other auxiliary means can be used to improve the extraction rate of wolfberry polysaccharides. For example, the release of polysaccharides within cells can be facilitated by the addition of co-solvents or enzymatic hydrolysants. At the same time, high-speed centrifugation or membrane separation technology can be used to remove impurities in the extract and improve the purity of polysaccharides.
Goji polysaccharides have a variety of biological activities, such as antioxidant, anti-fatigue, and immune regulation. Studies have shown that wolfberry polysaccharides have preventive and auxiliary effects on a variety of diseases. Through in-depth research and development, it is expected to make greater contributions to the cause of human health.
In the industrial production of wolfberry polysaccharides, factors such as production efficiency and cost need to be considered. Therefore, it is of great practical significance to study the process optimization and equipment realization of ultrasonic extraction of wolfberry polysaccharides. In the future, the extraction rate and purity of wolfberry polysaccharides can be further improved, the production cost can be reduced, and the application and development of wolfberry polysaccharides can be promoted by improving ultrasonic equipment, optimizing the extraction process, and developing new separation and purification technologies.
In conclusion, ultrasonic technology is an effective method for extracting polysaccharides from wolfberry. Through experimental research and process optimization, the extraction rate and purity of wolfberry polysaccharides can be further improved, which can provide strong support for the application and development of wolfberry polysaccharides. With the continuous progress of ultrasonic technology and the in-depth development of research, it is believed that the application prospect of wolfberry polysaccharides will be broader.
