Abstract

ABSTRACT Soaking summer squash in calcium prior to commercial blanching at 99°C decreased sloughing, increased sensory firmness and had no effect on lightness or pH of the canned product. Although blanching squash in calcium decreased sloughing, improved lightness, decreased pH and produced off‐flavors, the effect of hand blanching at 93°C with no calcium present increased sloughing, lightness, pH, and sensory firmness of the processed product. Adding calcium at the point of squash filling into cans after a commercial blanch produced no change in sloughing, decreased pH, increased sensory firmness and had no effect on lightness. Grade 1 squash exhibited the highest drained weight and lowest sloughing values. Drained weight increased at the end of the harvest season. Method of cultivation had no effect on the quality of canned squash.
