Stability of carotene from dried grass meal and of synthetic vitamin D3 in chick mash
Autor: M. E. Coates, V. H. Booth, S. Y. Thompson, C. P. Cox, M. J. R. Healy
Publikováno v: Journal of the Science of Food and Agriculture. 6:10-14
Two experiments were carried out to determine whether 5% of dried grass meal as a source of carotene, together with 1 i.u./g. of synthetic vitamin D3 (cholecalciferol), can satisfactorily replace cod-liver oil in providing vitamins. A and D3 in chick

The α-Tocopherol content of leaves as affected by growth rate
Autor: V. H. Booth, A. Hobson‐Frohock
Publikováno v: Journal of the Science of Food and Agriculture. 12:251-256
α-Tocopherol was quickly extracted from small samples of leaf with acetone, transferred to petrol, purified by two-dimensional paper chromatography, and determined by the Emmerie–Engel test. Fast-growing leaves of Lepidium sativum (cress), Lactuca

The loss of carotene from dried green crop during storage.—The gradient of loss through a stack
Autor: V. H. Booth
Publikováno v: Journal of the Science of Food and Agriculture. 7:114-119
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. an

Distribution of carotenoids in different parts of the carrot
Autor: V. H. Booth
Publikováno v: Journal of the Science of Food and Agriculture. 2:350-353
The concentration of total carotenoids in various sections of the root of the carrot was studied by extracting the fat-soluble yellow pigment and estimating it colorimetrically. The concentration had a general fall longitudinally from crown to tip al

The influence of environment and maturity on total carotenoids in carrots
Autor: S. O. S. Dark, V. H. Booth
Publikováno v: The Journal of Agricultural Science. 39:226-236
1. A study has been made of the effect of conditions of growing and of maturity on the concentration of total carotenoids (t.c.) in the root of the carrot, Daucus carota L.2. Carotene comprised nearly 90% of the total carotenoids in all categories of

Chromogenesis in stored carrots
Autor: V. H. Booth
Publikováno v: Journal of the Science of Food and Agriculture. 2:353-358
Freshly harvested carrots were stored at about 6°c. in a closed tin box. Loss of weight and mould growth were negligible. From time to time tiny cylinders were removed from each carrot and total fat-soluble pigment was extracted and estimated colori
