Changes in structure, rheology, and water mobility of apple tissue induced by osmotic dehydration with glucose or trehalose
The impact of osmotic dehydration to water activity [aw] at 0. 97 or 0. 94 with glucose or trehalose solutions on structure [optical and transmission electronic microscopy observations], rheological properties [small-scale dynamic oscillatory and creep/recovery measurements and large-scale compressi...

| 520 | |a The impact of osmotic dehydration to water activity [aw] at 0. 97 or 0. 94 with glucose or trehalose solutions on structure [optical and transmission electronic microscopy observations], rheological properties [small-scale dynamic oscillatory and creep/recovery measurements and large-scale compression force-deformation testing] and water mobility [ 1H-NMR spectra] of parenchymatous apple tissue was investigated. In general, the nature and the concentration of sugar employed significantly affected the material properties and the structure of apple tissue. A dramatic loss in rigidity [E d]; an increase in deformation at rupture [E RR], creep compliances [J0, J1, and J2], and fluidity [1n0] and a decrease in storage [G'] and loss [G''] moduli, true rupture stress [O RR], and proton transverse relaxation times [T 2i] were induced by osmotic treatments. E RR, C1, and T 2i parameters allowed to discriminate between the sugars used as osmotic agents while the different a w levels for each sugar resulted in changes in O RR, W, and T 2i values. Loss of turgor due to plasmolysis or rupture of membranes and desorganization/degradation of walls allowed explaining, at least partially, the changes in material parameters. | ||
