High-calcium corn oil with function of supplementing zinc, and preparation technology of corn oil

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of oil processing, in particular to a zinc-supplemented high-calcium corn oil and a preparation process thereof. Background technique [0002] Corn oil is extracted from corn germ. The fat content of corn germ is between 17% and 45%, accounting for more than 80% of the total fat content of corn. The fatty acid in corn oil is characterized by unsaturated fatty acid content as high as 80% %~85%, corn oil itself does not contain cholesterol, it has a dissolving effect on the accumulation of cholesterol in the blood, so it can reduce the hardening effect on blood vessels, corn oil is rich in vitamins A, D, E, easy to digest and absorb for children. [0003] Zinc exists in many enzyme systems and is an essential substance for the synthesis of nucleic acids, proteins, carbohydrates and the utilization of vitamin A. It can promote growth and development and improve taste. When zinc is deficient, poor taste and...

Calcium plays an important role in various growth and development stages of life, from childhood to adulthood and even old age. It is an essential element to ensure human health and longevity. At all stages of life, calcium nutrition must be paid attention to. If it can be supplemented early, the effect will be greater. Even better, in children and adolescents, calcium supplementation is helpful for physical development and the establishment of a higher peak bone mass. Due to special physiological conditions, pregnant women and breastfeeding women have increased calcium requirements and must increase calcium intake. 35-40 years old Increased calcium intake in the future can delay the rate of bone loss. Increased calcium intake in postmenopausal women and elderly men can effectively prevent osteoporosis and keep the body light and healthy. The best source of calcium is food, the traditional Chinese dietary calcium Mainly derived from plant foods such as vegetables and grains, but the absorption rate of calcium is low
