Benzyl Thiocyanate Taint in the Milk of Dairy Cattle ingesting Coronopus didymus Sm.

Naturevolume 207page640 (1965) | Download Citation



AN objectionable flavour is found in the milk of dairy cattle which graze on pastures infested with the cruciferous weed Coronopus didymus Sm. (bitter cress or land cress)1. This taint is of considerable concern in Queensland and New Zealand where the weed is widespread during winter; unlike many other fodder or weed taints in milk, it cannot be removed during the manufacture of cream or butter1,2. The taint in milk is characteristically a burning flavour with a sharp odour, while in butter it is a burnt flavour with a burning after-taste.
