Embodiment 1

[0037] (1) Screening and disinfection of corn kernels: After removing impurities and underfilled particles, the corn kernels are washed with clean water, left for 5-10 minutes, and the floating corn kernels are removed, and then soaked in 0.5% NaClO solution Sterilize for 25 minutes.

[0038] (2) intermittent seed soaking: the corn kernels in step (1) are washed with deionized water to clean the residual NaClO solution on the surface. At room temperature, soak for 7 hours and cut off water for 1 hour, and then soak for 2 consecutive times for a total of 16 hours.

[0039] (3) Soaking seeds under salt stress: soak in 5mmol / L calcium chloride solution for 8h at room temperature. After soaking the seeds, the residual salt solution on the surface of the seeds was washed with deionized water.

[0040] (4) Grain germination: put every 30g (20-25 grains) of corn grains in step (3) into a Petri dish (Ф15cm) padded with a double-layered filter paper that has been wetted, and place in...

[0045] (2) intermittent seed soaking: the corn kernels in step (1) are washed with deionized water to clean the residual NaClO solution on the surface. At room temperature, soak for 7 hours and cut off water for 1 hour, and then soak for 2 consecutive times for a total of 16 hours.

[0046] (3) Soaking seeds under salt stress: soaking in 0.5mmol / L calcium chloride solution for 8h at room temperature. After soaking the seeds, the residual salt solution on the surface of the seeds was washed with deionized water.

Embodiment 3

[0051] (1) Screening and disinfection of corn kernels: After removing impurities and underfilled particles, the corn kernels are washed with clean water, left for 5-10 minutes, and the floating corn kernels are removed, and then soaked in 0.5% NaClO solution Sterilize for 25 minutes.

[0052] (2) intermittent seed soaking: the corn kernels in step (1) are washed with deionized water to clean the residual NaClO solution on the surface. At room temperature, soak for 7 hours and cut off water for 1 hour, and then soak for 2 consecutive times for a total of 16 hours.

[0053] (3) Soaking seeds under salt stress: soak in 5mmol / L calcium chloride solution for 8h at room temperature. After soaking the seeds, the residual salt solution on the surface of the seeds was washed with deionized water.

Abstract

The invention relates to the field of development and utilization of biological resources, in particular to a method for enriching lutein with germinated corn, a product thereof and application. The method provided in the invention includes: taking corn grains with germination ability as the raw materials, conducting seed soaking in a calcium ion solution and dark culture, and then performing UV-Birradiation treatment. Determination shows that the method provided by the invention can improve the lutein content of germinated corn by 40% or more.

Description

technical field [0001] The invention relates to the field of development and utilization of biological resources, in particular to a method for enriching lutein by utilizing germinated corn, its product and application. technical background [0002] Lutein is an oxygen-containing carotenoid containing multiple unsaturated double bonds and ionone rings. It exists widely in nature and is the main component of plant pigments such as vegetables, fruits, and flowers. It is also the main component of human eyes. The main pigment in the macular region of the retina. In addition to having a certain effect on eye health, studies have also found that lutein has certain preventive and improving effects on various chronic diseases such as diabetes, cardiovascular disease, and cancer. Therefore, the development of foods rich in lutein has become a hot spot. At the same time, lutein has been allowed to be added in foods, beverages, cosmetics and health care products as food supplements....
