Show Copper Pipes Ruin Vita-mines Vita-mines in Milk j ONE of the causes of the deterioration of the vitamlnc whlcfc guards against scurvy Is , the catalysis or chemical action due to copper pipes This was Illustrated recently by en experiment ex-periment described by Alfred F Hess. He says -that milk heated in a copper vessel will loso considerable con-siderable of the antiscorbutic vltamlne, as com- 1 pared with milk heated in a glass container. Guinea pigs receiving milk pasteurized In e copper vessel will devolop scurvy, he states, whereas those which have been fed with milk which had been heated in glass do not devolop the disorder. , ' This experiment." continued Mr. Hess, "has a very practical application, for It is well known tha milk In process of pasteurization passes through copper plpL-s ft is true that they aro lined, but the lmlng frequently becomes defec-f:e defec-f:e after a short period. Lined copper vessels are eonnnonlv used In the course of condensing and drying milk It is, therefore, not astonishing astonish-ing that copper Is found very frequently in small amounts of milk "Quite apart from the question of the destruc- tlon of the vitamlnes, the last few years have demonstrated that 1 should not consider foodstuffs food-stuffs as entities from 'lie standpoint of their vitaminr content. A food may be rich or poor in th's factor according to attendant circumstances. For Instance, carrots cannot be classed as containing con-taining a definite nmount of antiscorbutic vita-mine. vita-mine. Tf they are fresh they will contain much more than If they r.re old. or again If they have been plucked young thv will have far more than If they war tough and old " |
