摘要：

The molecular weight of water-soluble and EDTA-soluble pectin from carrot following blanching, blanching + dehydration, and dehydration without blanching was determined by the viscometric measurement and gel permeation methods. The viscometric measurement indicated that after blanching + dehydration, the molecular weight of the water-soluble pectin increased 2.5-fold and that of EDTA-soluble pectin 2.3-fold as compared with the untreated tissue. Dehydration without blanching drastically decreased the molecular weight of the pectin in both fractions.
