Ultra-high-pressure technology has been taking the sterilization and inactivation of agricultural products and food as core research and application fields since its birth. This book first outlines the basic principles of ultra-high pressure and then introduces non-traditional applications of the ultra-high-pressure technology in agricultural products such as Baijiu (the Chinese liquor), brown rice, and wood. These applications were discovered by the author, as well as the representative quality improvements of treatment objects brought by these applications. Finally, the author puts forward his own ideas on the non-traditional application trend of ultra-high-pressure technology in the future. This book aims to broaden the thinking for the application and research of ultra-high-pressure technology in agricultural product processing and propose specific ideas for future research and application in this field on the basis of the author’s current research.
