Specific surface area changes and functional potential exploration of Pleurotus pulmonarius under ultrasonic frequency control

This article explores the changes in the specific surface area of <i>Pleurotus pulmonarius</i> under the control of different ultrasonic frequencies, analyzes the changes in flavor substances of <i>P. pulmonarius</i> and explores its functional nutritional potential. The results show that within a certain range, the specific surface area and pore size increase with the increase of ultrasonic waves, which has a significant effect on the release of flavor substances of <i>P. pulmonarius</i> and also affects its ability to adsorb and release substances. Therefore, controlling the specific surface area and pore structure of <i>P. pulmonarius</i> by ultrasonic frequency can make <i>P. pulmonarius</i> more effectively absorb nutrients in the surrounding environment and improve its nutritional value and availability.
