strawberry preservation

[xxbubblesxx]

I am doing a study to investigate how the preservation methods of strawberries can effect the vitamin c content, but i am finding it difficult to find any info on the processes of freezing and canning them and why the vitamin content would differ.

Also does anyone know whether added colourings may have an effect on the vitamin content i.e. allura red (E129)?????????

Any info would be greatly appreciated. thanks

I work on a berry-based project and if you e-mail me via the info link at www.berryscotland.com I can forward on a review of all the berry research, including info on preservation and the effects on vit. c content.
