Equipment and procedures for the rapid measurement of the water vapor
permeability of polymer films and food coatings has been evaluated. The
method uses an electronic sensor to measure the concentration increase in
water vapor diffusing through a film into a chamber of known volume. Air of
known humidity is...
The effects of mold level (Botrytis cinerea), processing method (fresh, individually quick frozen (IQF), frozen sugared sliced (FSS), freeze dried (FD), canned, and preserves), and maturity (underripe, normal, and overripe) and strawberry volatiles were analyzed by gas liquid chromatography (GLC) using on-column entrainment of headspace volatiles in aqueous extracts. Computerized...
Processing and storage of berry fruits is accompanied by various changes, the important ones being the changes in the soluble solids content, titratable acidity, pH, pigments, and texture. A study was made of these changes in processed strawberries, raspberries, blackberries and blueberries, still cooked and stored at 78°F for one...
