Abstract

The objective of this study was to establish a quantitative procedure for strawberry (Fragaria chiloensis) anthocyanins, and to apply this method of freeze-dried and frozen strawberries of three cultivars. The following information was presented:

1. The E for P-3-G in 1% methanolic HCl was determined to be 2.908 x 10⁴.

2. The E for C-3-G in 1% methanolic HCl was determined to be 4.89 x 10⁴.

3. A direct, quantitative procedure for the two anthocyanin pigments of the strawberry, including a simplified method of extraction.

4. Data indicating that the anthocyanin pigments of strawberries are unaffected by the process of freeze-drying.
