Preparation process of corn edible oil

Abstract

The invention discloses a preparation process of corn edible oil, which comprises: 1, mixing corn germ powder and citric acid according to a certain weight part ratio, extracting, and evaporating to remove a solvent to obtain corn crude oil; 2, performing standing and precipitating the crude oil for 40-60 minutes, filtering by using a filter, and deodorizing; 3, roasting the whole corn grains at the constant temperature of 50-60 DEG C through a stirring tank, and putting the roasted corn grains into a squeezer to be squeezed to obtain oil; and 4, washing the white sesame seeds and the perilla seeds with warm water, drying in the air, mixing and stirring with all the raw materials, heating to 100-115 DEG C, reacting for 1-5 minutes, standing, and drying to 35-40 DEG C. The method has the beneficial effects that the corn germ powder and the whole corn grains are used for branch type crude oil squeezing, the content and the quality of the crude oil in the initial step can be improved, so that the process treatment delicacy is improved, and the required reaction conditions in the whole preparation process become milder.

Description

technical field [0001] The invention relates to the field of edible oil, in particular to a preparation process of corn edible oil. Background technique [0002] Corn oil is corn germ oil. It is an oil made from corn germ. It has a golden color and an aromatic smell. Corn oil is rich in unsaturated fatty acids necessary for the human body. The content of unsaturated fatty acids is more than 80%, mainly linoleic acid and oleic acid. Among them, linoleic acid accounts for more than 50% of the total amount of oil, and the content of oleic acid is about 30%. Corn oil is also rich in physiologically active substances such as phytosterols (content up to 1.1%) and vitamin E (content up to 0.99%), It has high nutritional value, and its absorption rate is as high as 97%. It is a recognized healthy edible oil at home and abroad. Its main functions are to lower human cholesterol, lower blood pressure, soften blood vessels, increase human muscle, heart, and cardiovascular system. Preve...

Problems solved by technology

According to the publication number of Chinese patent document CN110358619A, a kind of vacuum roasting device for preparing corn oil by pressing the whole grain of corn is provided, which avoids the possibility of producing the carcinogen benzopyrene due to the high roasting temperature in conventional normal pressure roasting, The problem of effectively ensuring the safety and quality of corn oil products, but this equipment can only be used in one of the preparation processes, and can not get better effects of using corn oil from raw materials and other preparation processes, according to Chinese patent document, publication number is CN105875870A, provides a kind of corn oil and preparation method thereof, and it greatly reduces the content of Aspergillus flavus, and the corn oil of production keeps nutrient composition unchanged, and taste is pure, and fragrance is lasting, can satisfy People respond to the demand for original extra-grade corn oil with mild conditions, simple operation, and good application prospects, but it is difficult to guarantee the oil yield and the quality of the finished oil, and at the same time, its preparation process and materials are difficult to improve the smell and taste of the finished oil. and oil output
