“…If the cell walls were broken or damaged as on the edge of the section, then biopolymers of all sizes could enter the cells. The repeated observation of small sized polymers (TlO, T40 and T70) remaining near the cell walls also supported the hypothesis of Jen et al (1989) concerning the attachment of biopolymers to the cell walls of broken cells.…”

“…Dextran standards were modified into blue colored compounds suitable for use as markers in microscopic examinations. The dextrans were reacted with Remazol brilliant blue R salt according to the method of Rinderknecht et al (1967) and modified by Jen et al (1989). The dye-dextran complexes were assumed to have physical properties similar to natural dextrins.…”

“…The mode of action of these biopolymers in improving the quality of processed vegetables is uncertain. Jen et al (1989) suggested that the infusion of biopolymers into intercellular spaces and cell walls may reduce collapse of vegetable cells during the dehydration process. The hypothesis was partially verified by Jen et al (1989).…”

The penetration pattern of biopolymers in plant tissue during processing was studied. Carrot dices were infused with dye-dextran standards of different molecular weights (TlO, T40, T70 and T500). Polymers of smaller size were found within the intercellular spaces and the cell walls. Larger polymers were found only in broken cells near the surface of the tissue. Biopolymers of small size were theorized to provide strength to the cell wall of plant tissue and assist in maintaining cellular integrity during dehydration. This was further verified in that the dextrans of molecular weight of 10,000 produced best quality dehydrated carrots with high rehydration ratio, more retention of carotenoids and high water-holding capacity.

“…But, if it is possible to develop a porous structure, the texture is improved, the penetration of water during the rehydration is increased and the quality of the dehydrated product is generally better. For this a good knowledge of the shrinkage mechanism and the influence of process variables is needed (Jen, Mudahar, & Toledo, 1989;Mayor & Sereno, 2004).…”
