In this study, xanthan gum was used to produce cryogel and conversion of cryogel to oleo-gels, and the structural and chemical characteristics of the produced oleo-gels was investigated. Results showed, the produced oleo-gels (COS) contained about 66% oil content and they have able to holding oil at about 60%. The pseudo-second order model can predict the oil absorption kinetics of cryogels. There was no difference between the amount of fatty acids of sunflower oil and COS. 1H NMR and 13C NMR signals, the hydro peroxide (initial oxidation product) and aldehydes (secondary product oxidation) was not revealed in COS. Also, it was observed no exothermic process in the curve in the differential thermal analysis curve (DTA) up to 350 °C. AFM the formation of a uniform, homogeneous, and stable gel network that matched the results of the mechanical properties of the COS.
