Chilling injury affects kaffir lime leaves by low-temperature, but nonfreezing, temperatures. At these temperatures, the tissues weaken because they are unable to carry on normal metabolic processes. Various physiological and biochemical alterations occur in the sensitive species in response to low‐temperature exposure. These alterations lead to the development of a variety of chilling injury symptoms, such as surface pitting, discoloration , growth inhibition, wilting, loss of flavor, and decay. This review article describes the changes in membrane lipids, permeability, energy supply, respiration, and other metabolic processes that are affected by chilling temperatures.
