Effect of processing and storage on the texture of canned berries

Creator:: Rao, Akkinapally Venketeshwer
Abstract:: The texture of processed berry fruits changes both during processing and subsequent storage. A study was made of these changes in processed strawberries, raspberries, blackberries, and blue- berries, spin-cooked and stored at 100°F. for 28 days in tin and glass containers. Four samples, from each of the two replications of...
