Analysis of glycans in a Burnt-on/Baked-on (BoBo) model food soil using Microarray Polymer Profiling (MAPP) and immunofluorescence microscopy

•Microarray Polymer Profiling allows high-throughput mapping of glycans in food.•Hemicellulose, starch and pectin were detected using monoclonal antibodies.•Xylan is a major component of a model Burnt-On/Baked-On (BoBo) food polymer.•Burning during cooking causes cell-wall glycan structure disintegration.•Adding CAZymes to dishwashing detergents may improve cleaning of food soils.
