ConclusionsCommercial press‐cakes and petroleum ether‐extracted tung meals are toxic. The toxicity of press‐cake decreases markedly in common storage. The toxicity of oil‐free meals does not decrease under such storage. Many lipid solvents remove toxic material from tung products but cannot be used alone to produce a non‐toxic meal. Heat alone cannot detoxify tung meal or cake. Moistening increases the effectiveness of the heat treatment. Tung cake and meal may be detoxified by combining the moist heat treatment with solvent extraction. Two toxic materials are present in tung nuts. The biological value of tung protein is low insofar as the chick is concerned. It seems improbable that the value of the detoxified meal as a feedstuff would justify the expense of detoxication.
