The structure-texture relationship of blanched and glucose-impregnated strawberries
The effect of water or steam blanching, glucose impregnation to attain an equilibrium water activity (a w) value of 0.93 or 0.95, and the addition of calcium on textural characteristics of strawberries was analysed. Strawberries were softened by blanching, varying the maximum extrusion force from 53...

The effect of water or steam blanching, glucose impregnation to attain an equilibrium water activity (a w) value of 0.93 or 0.95, and the addition of calcium on textural characteristics of strawberries was analysed.

Major changes in texture occurred during blanching, while the influence of the impregnation step depended on the previous treatment.
