Carotenoids of Grass Silage


WHEN using Moon's1 method for the estimation of ‘crude carotene’ in routine silage samples, we have applied Moore's2 chromatographic technique for removing other chromogens from the carotene solution, as obtained by Moon's method, in order to obtain a value for ‘pure carotene’. In the case of silages the ‘pure carotene’ values may be considerably less than the ‘crude carotene’ values.
