HYDROXYPROPYL DISTARCH PHOSPHATE
Modification is carried out with 0.1 per cent. phosphorus oxychloride
and 8-10 per cent. of propylene oxide. Cross-linkage would be no
greater than is experienced on modification with phosphorus
oxychloride alone and other linkages would probably nol exceed 20 per
100 anhydroglucose units.
Digestibility was tested in groups of five rats fed for seven days a
basal diet supplemented by 0, 1 g and 3 g modified or control starch.
No difference in weight gain was observed (Prier, 1961).
There are virtually no suitable data available for evaluation.
Adequate metabolic studies preferably in man are required to elucidate
the fate of this compound and the moieties containing the various
modifying radials. Ninety-day studies in two species (one a non-rodent
mammal) are also required.
Not possible on the data available.
