4. Chemical kinetics âthe study of the rates of chemical processes 3. Reviews general modes of food deterioration, summarizes a general approach to the kinetics of food deterioration, and provides a kinetic approach to accelerating shelf-life deterioration. Physical Pharmacy, upon its publi-cation in 1960, provided great clarity and deï¬nition to a dis-cipline that had been widely discussed throughout the 1950s but not fully understood or adopted.
