Natural corn condiment and preparation method thereof

The invention relates to a natural corn condiment and a preparation method thereof and belongs to the field of food flavor ingredients. The preparation method comprises the following steps: crushing corn kernels into powder and sieving the crushed corn powder by a sieve of 60 meshes; mixing the corn powder with a 40%-50% edible ethanol solution; putting a mixture into hot water of 45-55 DEG C to be treated by a water bath for 1-2 hours; ultrasonically extracting the edible ethanol solution containing the corn powder for 20-40 minutes; carrying out ultra-filtration on centrifugal liquid by using a pipe type ultra-filtration film with the diameter of more than 10nm; concentrating by a reverse osmosis membrane and separating water; carrying out rotary distillation on an ultra-filtration reverse osmosis concentrated solution under reduced pressure and separating the water; freezing to prepare powder. The corn condiment prepared by the invention sufficiently utilizes corn biological sources; the corn condiment which can continuously keep the beneficial components is provided on the basis of not changing the corn components and is good for developing corn-flavor instant foods and beverages; the stability of the product is good.
