Note 54 — Chapter IX · TREATMENT
Reading edition
There is no relation whatever between the acidity of canned vegetables and their possible contamination with tin. Experiments carried out to determine this question demonstrated, for example, that a “sample of red kidney beans showing the highest acidity contained the least tin,” and that those samples containing the most tin were all relatively low in acidity.
