Processing of the FTIR spectra of acetylated wheat starch
Original language description
Compared to other cereal or tuber starches, wheat starch comprises mainly two different types of granules, so-called A-starch and B-starch, which are refined into two parts during starch processing. These types differ not only in size and shape but alsoin the chemical structure of amylopectin, its granular arrangement, and content of lipids and proteins. Wheat A- and B-starch was subjected to acetylation with acetic anhydride at temperatures in the range of 115 - 133°C and reaction time 0.5 - 12 hours.Then the sample was dried 2-3 days at a temperature of 40 - 45 °C and disintegrated. The degree of substitution (acetylation) of starch in the range of 0.5-3.0 was determined by 1H NMR using as a standard benzoic acid. These values were used for calibration and validation of infrared spectra of starches by Fourier transform spectroscopy. The infrared spectra were evaluated using programs Omnic, Statistica 8.0 and TQ Analyst, where the degree of acetylation was estimated using the PLS (P
