In the present work, the hydration and retro-gradation of mixtures of wheat starch and fructooligosaccharides in diluted hydrated matrixes were discussed. Rapid Visco-Analyzer, differential scanning calorimeter, Fourier transform-infrared spectroscopy, scanning electron microscopy, and x-ray diffraction were used to determine the properties of the mixture of wheat starch and fructooligosaccharides. Swelling of the wheat starch showed significant changes when the addition of fructooligosaccharides surpassed 0.1 g/g starch. Water absorption index showed obvious change but there was no regular variation. The water solubility index of starch increased after adding the fructooligosaccharides and the highest value was up to 19.85 as compared with the control (3.61). There was no significantly change for the pasting parameters of the mixture. Fructooligosaccharides significantly affected the enthalpy of wheat starch from the result of differential scanning calorimeter analysis, and enlarged the freezing scope of the mixture gel (from –23.09 ± 0.25ºC to –38.85 ± 0.32ºC). The melting enthalpy of sample with fructooligosaccharides decreased by 9.9 J/g as compared with the control. Fourier transform-infrared spectroscopy results showed that there were no obvious differences between the samples with or without fructooligosaccharides except that the O–H stretching vibration of hydrogen bond of the mixture gel strengthened after storage for 2 or 4 days. Scanning electron microscopy results indicated fructooligosaccharides should be conductive for starch to form fine gel structures and could inhibit the retrogradation of wheat starch. X-ray diffraction spectrum further illustrated the fructooligosaccharides could interfere with the retrogradation of wheat starch during storage. 相似文献

A controlled acid thermal hydrolysis process of fructans from agave (Agave tequilana Weber var. azul) was designed to produce a mixture of functional prebiotic fructooligosaccharides and sweetening power. Despite its highly branched structure, first-order kinetic behaviour with respect to substrate concentration was found with an activation energy of 95 kJ/mol, similar to the value found for other linear fructans such as chicory inulin. Fructose equivalent (FE) an analogous parameter to dextrose equivalent (DE) used in the starch industry was introduced to characterise fructan hydrolysis; maximum oligosaccharide production was observed when fructose equivalent (FE) reached 27–48 with a structural profile analysed by high-performance anion-exchange chromatography HPAEC-PAD. After hydrolysis, glucose and fructose may be eliminated through a biological purification step involving the addition of Pichia pastoris cells, which selectively consume these sugars but are unable to metabolise fructooligosaccharides. 相似文献
