Effects of high-pressure pretreatment and calcium soaking on the texture degradation kinetics of carrots during thermal processing

The high-pressure pretreatments combined with calcium chloride infusion can improve the texture of carrots during thermal processing as it retards the rate of thermal softening. Texture degradation, monitored by a texture analyzer, and the changes in the texture characteristics were associated with the degree of methylation of carrot pectins, which is independent of pectimethylesterase (PME) activity.
