This research aimed to produce high value-added products, including starch and carboxymethyl cellulose from saffron corms and corncob waste respectively, as well as active extracts from saffron corms and lignin from corncob wastes. In this study, the extraction yield, antioxidant capacity, and antifungal properties of extracts obtained from saffron corms and lignin produced from corncob waste, along with the physicochemical properties of starch derived from saffron corms and carboxymethyl cellulose produced from corncob waste were investigated. The extraction yields of saffron corm extract and lignin from corn waste were more than 14% and 17%, respectively. The phenolic content and radical scavenging activity of the saffron corm extract were 137.91 mg per 100 g dry weight and 29.31%, while for corn lignin, they were 156.69 mg per 100 g dry weight and 58.85%, respectively. The saffron corm extract and lignin exhibited antifungal activity but the minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of lignin were lower than those of the saffron corm extract due to the higher content of phenolic compounds in lignin. The ash and protein content of starch obtained from saffron onion was 0.16 and 0.75%, respectively, which is close to potato starch. The extraction yield of cellulose from corn wood waste was 38.43%, and the purity grade and degree of substitution of the carboxymethyl cellulose prepared from it were 73% and 85%, respectively. The results obtained from Fourier-transform infrared spectroscopy (FTIR) confirmed the formation of carboxymethyl cellulose from cellulose extracted from corn wood.
