Study of the thermostability of vitamin C. (OCoLC) Material Type: Thesis/dissertation, Manuscript: Document Type: Book, Archival Material: All Authors / Contributors: Christopher Leo Kenny. 1. Introduction. Vitamin C is important as a pharmaceutical agent, cosmetic ingredient, and dietary supplement.
Products containing vitamin C are often subjected to thermal treatment during preparation, processing, and storage,, so it is important to ascertain vitamin C's thermal decomposition kinetics and shelf l stability is of particular interest because the results of Cited by: The thermal stability of vitamin C (including l-ascorbic acid [l-AA] and dehydroascorbic acid [DHAA]) in crushed broccoli was evaluated in the temperature range of 30 to 90 degrees C whereas that of ascorbic acid oxidase (AAO) was evaluated in the temperature range of 20 to 95 degrees C.
Thermal treatments (for 15 min) of crushed broccoli at 30 to 60 degrees C resulted in conversion of l-AA to Cited by: Vitamin C is the first book to cover the history, chemistry, biochemistry, and medical importance of vitamin C and is the first to provide an in-depth, interdisciplinary study of this essential and fascinating compound.

Substantial updates have been made to chapters on vitamins A, C, E, K, folate, and the quasi-vitamins; Provides checklists of systems affected by vitamin deficiencies and food sources of vitamins; Key concepts, learning objectives, vocabulary,case studies, study questions and additional reading lists are included making this ideally suited for.
Vitamin C is the most unstable vitamin which can be easily denatured. At high temperature, in the presence of sun light and oxygen present in air, vitamin C reacts and it is oxidized. Excessive amounts of heat can destroy vitamin C completely. At 70°C vitamin C is denatured so it should be preserved below 70°C to avoid heat damage.
Get your students to test their fruit and vegetables for vitamin C using simple kitchen equipment and household items The procedure to take part in the global experiment, measuring the quantity of vitamin C in fruit and vegetables, is detailed below.
