The low-dose gamma irradiation of dilute aqueous pectin solutions after appropriate adjustment of pH with hydrochloric or certain other inorganic acids leads to the formation of thermoreversible gels. Maximum gel strength is attained only under optimum conditions of pH, concentration, temperature, radiation dose, and exposure time, and only in the absence of oxygen and a number of radiation protectants.
