Project Number: 5358-22000-033-05
Project Type: Grant

Start Date: Jun 20, 2005
End Date: Sep 30, 2008

Objective:
To determine antioxidant activity, total phenolics, anthocyanins, and ellagic acid of canned, frozen, dehydrated berries, and berry jams. Strawberries, raspberries and blackberries are the berries studied in this project.

Approach:
Products made from Northwest raspberries, strawberries, and blackberries will be evaluated in this study. Each category of the samples will be selected from at least 2 Northwest berry processors. When it¿s necessary, products from different varieties of the same type of berry will be examined to gain knowledge on the variety effect. Berry samples will be extracted using the method of Kalt et al. (2000). All samples will be subjected to the analysis on their total phenolics, anthocyanins, ellagic acid, and antioxidant capacity.
