High-oleic peanut is favored by consumers because its a longer shelf life and benefits for cardiovascular health. Up to the high-oleic standard and with good taste is essential for peanut products in food processing. The aim of present study was to explore the effect of foliar fertilizers on chemical and eating quality of high-oleic peanuts. Three high-oleic peanut cultivars, namely Huayu 09C2, Huayu 9621, and Huayu 962, were used as materials. Huayu 09C2 and Huayu 9621 were planted in Fuxin, Liaoning, foliar sprayed with Fosforil at 2250 mL/ha, and Huayu 962 was sown in Jvnan, Shandong, foliar sprayed with Foliplus at 1500/3000 mL/ha. The chemical and sensory quality of peanut harvested from the treatment plots and controls was evaluated. Results showed that, Huayu 09C2 and Huayu 9621, foliar spraying with Fosforil in Fuxin, Huayu 962, foliar spraying with Foliplus in Jvnan, all still maintained high oleate content levels, and the Fosforil treatment was effective in raising the in-tensity of sweetness of roasted kernels. This study demonstrated the feasibility of improving chemical and sensory quality of high-oleic peanut through foliar fertilizer.
