Mechanical properties and microstructure of frozen carrots during storage as affected by blanching in water and sugar solutions

•Mechanical and structural properties were affected by process, frozen state and sugar enrichment.•SEM analysis evidenced a thermoprotective effect of sugars on over-blanched carrots.•SEM analysis showed a cryoprotective effect exerted by sugars upon frozen storage.•Trehalose thermo-protection on PE...
