Sažetak
Relaxation time 'f1 for proton spin-lattice relaxation was
measured by the 90-90° pulse method over a temperature range
from -150 to + 120° C in starches of various origin, and in both
starch fractions, in soluble starch, in the amylase iodine complex,
and in deuterated starches and starches of different humidity. At
24 MHz resonant frequency a common T 1 - minimum of about
0.1 sec with a relatively low activation energy (1.3 to 2.1 kcal/mol)
is found at temperatures above o° C. The comparative study of
different starches indicates that the T 1 - minimum is caused by
the rotation of -CH20H groups in the starch molecule.
