"The manufacture of flavoring extracts belongs properly to the art of pharmacy, but the business, through competition, has fallen into such hands that there is no longer any uniformity in the quality nor excellence in much that is made."
W. S. Snow, Ph. C.
An attempt at excuse for producing this monograph might, perhaps, be strengthened by reference to our text-books, especially our works on pharmacy. They tell of flavored syrups, but nothing is said of flavoring extracts. Hence, we see queries from druggists in pharmaceutical journals, asking for information regarding literature on this subject, and the reply that follows, "there is no work on flavoring extracts published, to our knowledge."
Thus we see that the manufacture of flavoring extracts, so far as our knowledge goes, is the only branch of industry which can be classed as an art, that has no written law by which it may be governed.
For every existing fact in nature there is said to be a cause; likewise, there may be good reasons for this existing fact.
*Note - The terms Concentrated Extracts, Concentrated Tinct ures and Concentrated Essences, as referred to in price lists, often mean the same.
To make a good flavoring extract, requires great care, as well as a critical taste which will enable the operator to judge of the quality of the materials used.
It has been said that no careless man need attempt the business of wine making, for he will surely fail. We will say that in the manufacture of flavoring extracts no careless or ignorant man need attempt their preparation, for he will utterly fail.
We have on several occasions been asked by grocers our opinion of the quality of specimens of extracts offered for sale by manufac-turers, and, as a rule, when the price was fair the extract was found to correspond with the price. Likewise, when a cheap article was offered, it was found invariably poor.
This rule, although holding good in the main, like all others, has its exceptions; especially is this so in cities, and more particularly in case of supplies furnished to confectioners, bakers and restaurants, when the article is sold in bulk. Men of much enterprise and little knowledge essay to enter a business and produce goods of which they know nothing. To secure business, they cut prices, and of necessity, they buy cheaply (the poorest is given them), common alcohol, often below the average, oils inferior, result, an extract unfit for use. We have seen such goods where the flavor was distinctly perceptible, but where the fusel oil was the more prominent of the two. While intending to make strong goods they, perhaps, put in the full amount of flavoring principle, but not understanding the conditions necessary to make a good extract, failed.
