The application discloses a
selenium nutrient composition and a simple preparation method thereof, and belongs to the technical field of
selenium-containing
food processing. The
selenium nutrient composition is prepared from ordinary garlic
processing by-products and selenium-rich water as raw materials, and high-efficiency selenium enrichment is realized in one step by adopting a supercritical extraction technology, and selenium-rich
garlic powder, garlic
essential oil and garlic crude extract are simultaneously prepared. The raw materials are easy to obtain, the process is simple, green and environment-friendly, and the
utilization rate of garlic resources is greatly improved. By adjusting process parameters such as the amount of selenium-rich water and the extraction time, the selenium content of the selenium-rich
garlic powder can be accurately customized to adapt to the individual selenium supplement needs of different groups of people. The extraction process effectively separates
sulfur compounds in garlic, significantly reduces the pungent smell of the product, and the product has better
palatability. The prepared selenium
nutrient composition can be widely applied to various
food processing such as tablet candies and
solid beverages, and has the advantages of
nutrition, practicability and industrialization promotion value.
