Laboratory Handbook For Oil And Fat Analysts PDF Download

Excerpt from Aids in the Commercial Analysis of Oils, Fats, and Their Commercial Products: A Laboratory Handbook The following methods are given as works methods, and it must be clearly understood that the chemical methods used in the analysis of oils and fats can, from their nature, have no pretence to a degree of accuracy such as it usually found in inorganic work. The majority of the processes used in the analysis of oils are dependent on the use of solvents, and consequently the result obtained varies with the season of the year and many other factors. There has been a great tendency of late years towards building up theoretical foundations for the various methods used, and yet in commercial work products are obtained which cannot be made to yield concordant results in duplicate estimations, and also, as will be seen from the results given later, some of the processes which are supposed to be on settled bases give results which are quite inexplicable on the current theories. All the figures given are now published for the first time. I have not entered into theoretical discussions for the reasons given above, and it appears to me that workers are much needed who will consider their results without attempting to bind themselves to preconceived notions.
