Abstract
Seven peach varieties were canned conventionally with added syrup or added water and using high vacuum flame sterilization (HVFS) with and without added syrup. The treatments were assessed for sweetness, sourness, odor intensity, darkness of color, firmness by bite and firmness by visual appearance, using ranking and R‐index measures. Cross‐sensory interference was minimized by the excluding or reducing of the effects of inappropriate senses. Conventionally canned peaches were less firm to the bite but this did not correspond with visual appearance of firmness. Peaches canned with added syrup tended to be sweeter and less sour. Color and odor differences were less clear cut. Comparisons were also made with fresh peaches.
