Aeropectin had pore sizes that varied from mesopores to small macropores and compression moduli in the range from 4 to 18 MPa. Aeropectins show plastic deformation up to 60% strain before the pore walls collapse. Pectin aerogels have a thermal conductivity below that of air in ambient conditions, making them new thermal superinsulating fully biomass-based materials. The contribution of gas and solid conduction plus radiative heat transfer were determined and discussed. %G English %L hal-01022581 %U https://minesparis-psl.hal.science/hal-01022581 %~ INSTITUT-TELECOM %~ ENSMP %~ CSTB %~ CNRS %~ ENSMP_CEMEF %~ PARISTECH %~ L2C %~ PSL %~ MIPS %~ ENSMP_DEP_MM %~ UNIV-MONTPELLIER %~ ENSMP_DR %~ ENSMP-PSL %~ UM-2015-2021 %~ TEST3-HALCNRS
