Juice extracted from lowbush blueberries was used to prepare a low-calorie jelly. Extraction methods included cold-extraction, hot-extraction, and enzyme-extraction. Enzyme-extraction produced the highest yield and least viscous juice with lighter and redder color than other extraction methods whereas hot-extracted juice had an intermediate yield, greatest viscosity and darkest color. Cold-extracted juice made the hardest jelly. Jellies prepared from cold-extracted and enzyme-extracted juices were darker and had a more intense purple color than the corresponding juices, whereas jelly prepared from hot-extracted juice was lighter and redder in color than its corresponding juice.
