Unique Hydration Behavior of Potato Starch as Determined by Deuterium Nuclear Magnetic Resonance

“…lb for a polycrystalline powder. more, an increased dipolar broadening of the deuterium peaks in the powder pattern of D,O was observed at the lower hydration levels in powders, in agreement with the mechanism previously suggested for other biological systems (Baianu et al, 1984). The effect of subjecting the quadrupolar theoretical spectrum of a powder (solid line A, in Fig.…”

Carbon-13 nuclear magnetic resonance studies of chemically modified waxy maize starch, corn syrups, and maltodextrins. Comparisons with potato starch and potato maltodextrins

“…NMR relaxation studies of differences in the gelatinization behaviors of corn, wheat, and potato starches were also reported recently (Yakubu et al, 1990) and indicate that there are indeed significant differences not only between cereals and tuber starches but also between cultivare of the same plant. Although some of the structural differences between starches from different plant sources are known, the details of the changes occurring during gelatinization are still being debated.…”

Proton NMR relaxation and viscosity measurements on solutions and suspensions of carbohydrates and starch from corn: the investigation of carbohydrate hydration and stereochemical and aggregation effects in relation to oxygen-17 and carbon-13 NMR data for carbohydrate solutions

“…The hydration behavior of carbohydrates is of special interest in this context (Tait et al, 1972;Franks et al, 1973; Biswas et al, 1975;Sugget, 1976; Mora-Gutierrez and Baianu, 1985). Understanding the hydration behavior of biopolymers has recently made much progress with the application of high-field nuclear magnetic resonance techniques (Baianu et al, 1982(Baianu et al, ,1985(Baianu et al, ,1988Laszlo, 1983;Pessen and Kumosinski, 1985; Lioutas et al, 1986Lioutas et al, -1988; Kakalis and Baianu, 1988).…”
