Alpha-dextrins

Inclusion compounds of the Cg aromatic compounds with tris((9-phenylenedioxy)cyclotriphosphazene have been used to separate the individual isomers (43—47). The Schardinger dextrins, such as alpha-cyclodextrin, beta-dextrin, and gamma-dextrin are used for clathration alpha-dextrin is particularly useful for recovering PX from a Cg aromatic mixture (48,49). PyromeUitic dianhydride (50) and beryllium oxybenzoate (51) also form complexes, and procedures for separations were developed.

Phosphorus in starch is found in different forms, mainly starch phosphate monoester, phospholipids, and inorganic phosphate. 31P NMR spectroscopy was used to identify each of these forms in alpha-dextrins prepared from starches of different sources.128 Quantitative analysis was possible in DMSO solution. 

During illness, carbohydrates can be provided as small frequent meals, as drip-feeding, and sometimes as continuous drip-feeding. Using alpha-dextrin maltose preparations has the added advantage of low osmolality and easy digestion. 

Concentrated solutions of alpha-dextrin maltose can be used [3]. They have a low osmolality and are easily digested. The concentration that can be tolerated increases with age 15 % in infants less than 1 year, 20 % at 1-3 years, 25 % 3-6 years, and 30 % from age 6 years on. The amount can be calculated from Table 6.1.
