A process for treating raw liquid latex to destroy antigenic protein in the latex without causing undesirable alterations of physical characteristics of the liquid latex, whereby articles made from the treated liquid latex do not produce an adverse reaction in persons sensitive to the antigenic protein. A preferred process according to the invention utilizes pasteurization equipment and procedures, wherein cold raw liquid latex is supplied to a pasteurization apparatus to heat the raw liquid latex to a pasteurization temperature of from about 140° F. to about 210° F., hold the heated latex at the pasteurization temperature for a predetermined period of time sufficient to destroy antigenic protein in the latex, and then cool the pasteurized liquid latex for subsequent handling. In one embodiment of the invention, the process uses a batch pasteurizer, and in the preferred embodiment uses a continuous plate pasteurizer.
