Geotrichum candidum arthrospore cell wall particles as a novel carrier for curcumin encapsulation

•G. candidum arthrospore cell wall particles (APs) were made by chemical method.•Curcumin was encapsulated into APs via vacuum infusion to obtain Cur-APs composite.•APs had curcumin-loading efficiency of 36.5 % and yield of 730.6 μg/g (wet basis).•Curcumin in Cur-APs showed excellent storage, thermal and antioxidant stability.•Simulated digestion showed that curcumin in APs had a max bioaccessibility of 65.6%.
