SUMMARYBlanched and unblanched dice of carrot phloem were dehydrated at two different rates and stored for periods up to 6 months. The rehydrated volume was always greater for blanched dice than for unblanched. In all samples, the rehydrated volume decreased as a result of storage. No consistent differences among samples could be attributed to differences in rate of dehydration. Cellulose, extracted from the dice, was examined for crystalline content by water‐vapor sorption, X‐ray diffraction, iodine adsorption, enzymatic digestibility, and density methods. All methods agreed in showing a higher crystallinity in unblanched than in blanched samples, a continual increase in crystallinity in all samples as storage time increased, and no notable differences in crystallinity as a result of different dehydration ra
