The time for roasting pine nuts in the air fryer is ten minutes. The optimum temperature for roasting pine nuts in air fryer is 170 to 180℃ and roasting for 10 min. This temperature range can ensure that pine nuts are heated evenly during baking, and pine nuts are baked quickly and evenly. It should be noted that in order to avoid the pine nuts from being burnt, the frying basket can be suspended in the roasting process to ensure uniform heating, and the roasted pine nuts can be taken out and put on a shelf for cooling, so as to avoid the influence of excessive temperature on the taste. The temperature setting of air fryer has a direct influence on the time of roasting pine nuts. Too high or too low temperature will affect the baking effect of pine nuts. If a lot of pine nuts are roasted at the same time, it is necessary to extend the roasting time to ensure that all pine nuts can be evenly heated and cooked.
