The invention relates to a preparation method of natural corn stigma and corncob essence. The method comprises the following steps: mixing corn stigma and corncob, adding an aqueous solution with a certain mass ratio to the corn stigma and corncob, and pulping by a double-channel pulping machine; adding the pulped mixture of the corn stigma and corncob into a concentrator with vacuum, and carryingout vacuum concentration; adding medium-chain triglyceride into a vacuum pump buffer tank of the concentrator, and carrying out circulating cooling on the medium-chain triglyceride in the tank through an ice cooling unit; allowing gas evaporated by the concentrator to direct enter the vacuum pump buffer tank from the lower part of the buffer tank without being condensed; after the concentration is finished, discharging the liquid in the vacuum pump buffer tank, adding a edible salt into the liquid, and standing to fully stratify the liquid; discharging a lower-layer water phase, and collecting and filling an upper-la
