Abstract

Considerably more carotene was lost from the middle of a commercial type stack of dry lucerne meal than from the edges. The percentage loss, small near the outermost edges of paper sacks which were exposed to air, rose sharply in the first few cm. and then more gradually to the centre of the stack. Part of the increased loss in the centre was due to the higher temperature there. The major part of the difference in the rates of loss was due to the protective effect of moisture taken up from the air at the outer surfaces of the stack. These conclusions were verified by isolating sections of stacks of dry meal in tubes 21/2 metres long closed at one end and so stored as to eliminate temperature gradients. Loss of carotene was high within a tube except near the exposed end where moisture had been taken up.

## Abstract Carrot strips were scalded in (a) water, (b) solutions of sulphite, (e) solutions of starch, pectin or gelatin, and dried. The dried strips were stored in air in sealed cans. The ratio of loss of carotouoids from the carrot strips was the same whether they had been scalded in water or i
