Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of flour processing, and in particular to a processing technology for organic calcium-rich and organic selenium-rich wheat flour containing Cichorium glandulosum Boiss. Background Art
[0002] In recent years, with the increasing demand for healthy foods, the development of functional flour has become an important direction in wheat processing technology. As a wheat variety rich in selenium, organic selenium wheat plays a significant role in enhancing immunity, antioxidation, etc. With the continuous improvement of people's attention to healthy diet, Cichorium glandulosum wheat flour, as a kind of flour rich in nutrients and with characteristics, has gradually been loved by more consumers, and the market demand is also gradually increasing.
[0003] However, the growth cycle of traditional organic selenium wheat is relatively long, and the processing of organic selenium wheat flour is time-consuming and laborious, which leads to a relatively high cost of obtaining Cichorium glandulosum wheat flour, and a new process needs to be provided to improve this situation. Summary of the Invention
[0004] To solve the problems mentioned in the background art, the purpose of the present invention is to provide a processing technology for organic calcium-rich and organic selenium-rich wheat flour containing Cichorium glandulosum Boiss.
[0005] The described processing technology includes the following steps:
[0006] S1. Obtain selenium-rich wheat sprouts, and the method is as follows: Select healthy wheat seeds, soak them in selenium-rich nutrient solution for 20 - 24 hours to allow the wheat seeds to fully absorb the nutrient solution, then wash the wheat seeds, put the washed wheat seeds into a germination box for primary germination, with a germination time of 3 - 4 hours. During the germination process of the wheat seeds, they absorb the selenium in the nutrient solution and combine with their own proteins to form selenium proteins. After the primary germination is completed, the wheat sprouts are cycled through the processes of soaking in selenium-rich nutrient solution and germination. Among them, soak for 2 - 3 hours and germinate for 3 - 4 hours each time, and perform 23 - 25 cycles to obtain selenium-rich wheat sprouts, and then dry the selenium-rich wheat sprouts;
[0007] S2. Respectively take the dried selenium-rich wheat sprouts and dried Cichorium glandulosum Boiss. and perform coarse grinding to obtain selenium-rich malt powder and Cichorium glandulosum powder;
[0008] S3. Pour the Cichorium glandulosum powder and selenium-rich malt powder into a mixer according to a ratio of 10 - 15:85 - 90 for preliminary mixing, with a mixing time of 5 - 10 minutes;
[0009] S4. Perform ultrafine grinding on the preliminarily mixed powder, with a pressure of 0.8 MPa, a temperature of 10 - 20 °C, and a grinding particle size of 1 - 10 μm;
[0010] S5. Pour the ultrafine ground powder into a mixer for fine mixing, with a mixing time of 20 - 30 minutes;
[0011] S6. Low-temperature dry the finely mixed powder at a temperature below 45°C for 2 - 4 hours, with the moisture content of the powder being 10 - 12%;
[0012] S7. Screen the powder after low-temperature drying to obtain qualified nutritious flour.
[0013] Further, in step S1, the selenium-rich nutrient solution is a sodium selenite solution, and the concentration of the sodium selenite solution is 0.15% - 0.2%.
[0014] Further, in step S1, during the germination period of wheat seeds, spray and rinse with water.
[0015] Further, in step S1, the drying method is: first air-dry the selenium-rich wheat sprouts naturally, and then put them into an oven to dry until the water content drops to less than 11%.
[0016] The beneficial effects of the present invention are as follows: Improve the production method of selenium-rich wheat sprouts. The produced selenium-rich wheat sprouts not only have rich organic selenium content, but also have a simple production process, a short production cycle, and low costs. And through the steps of preliminary mixing → ultrafine grinding → fine mixing, without destroying the nutrient elements, the qiegao powder and selenium-rich wheat flour are fully mixed, and nutritious qiegao wheat flour can be obtained quickly and in large quantities, which is suitable for commercial promotion. Specific Embodiments
[0017] The technical solutions of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the protection scope of the present invention.
[0018] Example 1
[0019] A processing technology for nutritious flour containing qiegao organic calcium and wheat organic selenium includes the following steps:

Then wash the wheat seeds and put the washed wheat seeds into a germination box for the first germination for 4 hours. During the germination process of the wheat seeds, they absorb selenium in the nutrient solution and combine with their own proteins to form selenoprotein. After the first germination is completed, soak the wheat sprouts in the selenium-rich nutrient solution and perform the germination process in a cycle. Among them, soak for 3 hours and germinate for 4 hours each time. After 25 cycles (one week), the malt can grow to about 2 cm. Then air-dry the malt naturally for 24 hours, and then put the malt into an oven and dry it at 65°C for 9 hours to reduce the water content of the malt to 10%. Among them, during the germination period of the wheat seeds, spray and wash with water to prevent the wheat layer from sticking and at the same time play a role in cooling;
[0021] S2. Respectively take the dried selenium-rich wheat sprouts and dried Cichorium glandulosum Boiss. and conduct coarse grinding to obtain selenium-rich malt powder and Cichorium glandulosum Boiss. powder;
[0022] S3. Take 100 g of Cichorium glandulosum Boiss. powder and 900 g of malt powder and pour them into a mixer for preliminary mixing for 10 minutes;
