These notes on Jam, Jelly and Marmalade
present both theoretical and practical information on the processing of Jam,
thus offering the reader both the principles and practices of small and medium-scale Jam processing. In
preparing these notes of 137 pages help from several books, technical
literature of commercial pectin manufacturers and other published matter is
liberally taken. Besides, it includes my practical factory experience of 35 years
in jam making.
Although
successful results under factory conditions can be obtained purely on the basis
of the skilled operator's experience, it must be emphasized that such
experience if based on a thorough understanding and application of the scientific
principles involved will be very helpful in developing new recipes and
troubleshooting if they arise.
