OIL FROM GRAPEFRUIT
Americans were told recently that grapefruit rinds, instead of being discarded, can be used as raw material for valuable essential oils used as flavors and perfumes. About ,100,000 tons of grapefruit are processed annually by United States canners, and at least half of the rinds could be profitably collected. This quantity of rinds should produce about 50,0001b. of essential oils. Government chemists have found that the grapefruit oil contains 90 per cent, of limonene, or oil of lemon, two to three per cent of volatile constituents, and seven to eight per cent of non-volatile, waxy constituents. Oil of lemon is used in many perfumes, and the other ingredients are used for sharp odour and flavours. In the terpen free oil of the Florida grapefruit the following constituents are identified —actyl and decyl aldehydes, geraniol and octvl alchohols (both free and combined), cadiene, and small quantities of citral and methyl anthranilate. The latter is the flavour of grapes, and is manufactured synthetically to flavour some grape juices.
