The quality of these extracts is governed by the freshness and quality of the oil of lemon employed in making them, for, as a rule, the extract of lemon used in flavoring is made from the oil. If the oil be old, it is likely to acquire a turpentine-like odor; and even though of moderate age, it often loses its fresh lemon sweetness and becomes harsh. Oil of lemon, like vanilla beans, may be obtained in commerce of different qualities and at different prices. Those proposing to make flavoring extracts of lemon from the oil should pay special attention to its quality. There is little economy in purchasing cheap oil of lemon. At the present time it is possible to obtain this oil (hand-pressed is the best) of unquestionable purity. The pharmacist may, as a rule, depend upon the statement made by the jobbing druggist concerning the quality of the oil, and, if he is willing to pay the price demanded for a first-class oil, he can readily obtain it. We will add that it is not always possible (without great experience) to prejudge the value of oil of lemon by the odor. Upon the contrary, it is possible for an oil of lemon that has a very pleasant odor to produce an extract that shows evidence of turpentine, especially after having been mixed with syrup.
