Abstract
ABSTRACTPepper rings packed in brine containing CaCl2 were firmer, had higher bound calcium, chelator soluble pectin and pectin DE, and less water‐soluble pectin (WSP) than peppers packed in brine containing no CaCl2. Pepper rings packed in low acid brines (1% and 1.2% acetic acid) were firmer and had less WSP than those packed in high acid brine. Those samples (4% acetic acid) resulted in softening and pectin solubilization, but CaCl2 resulted in less softening. Monosaccharide composition of cell walls was not affected by CaCl2 or acetic acid. Firmness retention in CaCl2 treated samples was probably due to greater association between calcium ions and pectic substances, which resisted acid hydrolysis.
