The invention relates to the technical field of 
oil processing, and in particular relates to high-
calcium corn oil with a function of supplementing 
zinc, and a preparation technology of the 
corn oil. The preparation technology comprises the steps of taking fresh 
lichen and turnip, cleaning, putting the cleaned 
lichen and turnip into a beater to prepare 
slurry, feeding ground cheese and 
vitamin B3 into the 
slurry, evenly mixing, and placing in a sealing way; feeding 
protease into crab shells, dried clams and sardines, carrying out enzymolysis for 4-5 hours, 
drying the crab shells, the clams and the sardines, 
grinding and screening by a 40-mesh 
sieve body; cooking 
yolk, 
goose liver and 
chicken liver, then 
grinding, extracting for 4 hours by taking CO2 as a 
solvent, and separating the first oil and residue; heating the 
corn oil up to 145-150 DEG C, evenly mixing the 
lichen and the turnip which are treated by enzymolysis, the crab shell 
powder, the clam 
powder, the 
sardine powder, the 
yolk residue, the 
goose liver residue and the 
chicken liver residue, frying the mixture in the heated corn oil for 1-2 minutes, and removing oil residue by 
filtration to obtain the second oil; squeezing the oil residue in an oil press to obtain the third oil; evenly mixing the first oil, the second oil and the third oil to obtain the high-
calcium corn oil with the function of supplementing 
zinc. The high-
calcium corn oil is simple in formula and easy in material obtaining; the processed corn oil contains rich 
zinc and calcium, so that the defect that the 
edible oil on the market at present does not contain zinc is overcome; the 
food material cooked by the corn oil is delicious and is capable of supplementing zinc and calcium which are needed by the daily life of a 
human body, so that the corn oil is a simple and convenient method for supplementing zinc and calcium for families who seldom eat the food materials with higher zinc content.
