The effects of parboiling and of freezing at −18, −40°C or in liquid nitrogen on quality of cooked rice was studied for three Spanish varieties, Bahia, Sequial and Italpatna, using instrumental and sensory measurements. Parboiling prior to cooking and then freezing reduced rice quality. Freshly cooked samples differed from frozen cooked samples for firmness as measured instrumentally but not for any of the sensory parameters. Principal component analysis did not separate samples on the basis of their varietal quality.
