The enhanced extraction of oil by the ultrasonic field of oil extraction can significantly increase the extraction efficiency, improve the quality of oil, save raw materials, and increase the amount of oil extracted. Ultrasonic field can not only intensify the extraction process of substances by conventional fluids, but also intensify the extraction process of substances in the supercritical state. In the process of ultrasonic-enhanced supercritical CO2 fluid extraction, wheat germ oil is extracted from malt germ. After supercritical fluid extraction with ultrasonic field, the extraction rate of wheat germ oil is increased by about 10% without causing degradation of wheat germ oil.
Protein extraction Ultrasonic extraction also has significant effects on protein extraction. Ultrasonic waves can not only pulverize the above-mentioned embryos in water, but also liquefy 80% of the proteins, and also extract thermally unstable 7S protein components. Ultrasonic treatment can increase the protein extraction rate; ultrasonic treatment can also increase the separation temperature of the slurry and reduce the viscosity of the slurry, which can be used to directly produce high-protein soy milk products. The soybean slurry of different concentrations, the heat-treated soybean slurry before grinding and the separated bean dregs are subjected to ultrasonic treatment. Compared with the untreated soybean slurry, the protein content of the soybean milk after ultrasonic treatment has been significantly increased, and the increase range is 12%-20%.
Compared with the traditional technology of ultrasonic polysaccharide extraction, ultrasonic enhanced extraction has simple operation, high extraction rate, no material loss and no side reactions during the reaction process. The extraction of polysaccharides from Flammulina velutipes fruiting bodies can be enhanced by ultrasound, which can increase the extraction rate of polysaccharides by 76.22%; the extraction rate of Tremella fuciformis polysaccharides with ultrasonic hot water extraction is 5% higher than that of enzymatic method, and the extraction time is greatly shortened. Ultrasonic extraction of natural spices has a significant effect on the extraction rate. Ultrasound strengthens the supercritical fluid and extracts (SSFE) capsaicin from peppers. The results of ultrasonic extraction of valerian spice and the results of extraction without ultrasonic were compared. The absorbance of the filtrate and the absorbance of the filtrate using ultrasonic was 12%-40% higher than that of the filtrate without ultrasonic.
Food analysis For food analysis applications, ultrasonic extraction is also used for the pretreatment of food samples. The national standard (GB5009.696) acid hydrolysis method for determining the fat content of luncheon meat is time-consuming and cumbersome, and it is difficult to master because of human factors. The method of acid hydrolysis to determine the fat content of luncheon meat has been improved by using ultrasound. Ultrasonic extraction of samples does not require heating, which shortens the digestion time of samples. It can simultaneously determine the fat content of large quantities of samples. Ultrasonic extraction equipment technology and conventional extraction technology , Ultrasonic assisted extraction is fast, cheap and efficient. Compared with the water boiling and alcohol precipitation process, ultrasonic extraction has the following outstanding characteristics: no high temperature, atmospheric pressure extraction is required, safety is good, operation is simple and easy, maintenance is convenient and has a broad spectrum. Wide applicability. Ultrasonic extraction equipment can be used for most of the various components of Chinese medicinal materials. Ultrasonic extraction has a small relationship between the nature of the solvent and the target extract. Reduces energy consumption. The processing volume of raw materials is large, and it is doubled or several times higher, and there are few impurities. , The effective ingredients are easy to separate, the purification and extraction process cost is low, and the comprehensive economy
