2results about How to "Increase selenium content" patented technology

The application provides a preparation method of selenium-rich rice vermicelli and belongs to the technical field of food processing. The preparation method comprises the steps of rice pretreatment, selenium-rich rice bran pretreatment, raw material mixing, grinding, steamed powder extrusion, cooling and shaping, drying and packaging, and parameters of each step are optimized to ensure that process stability and product quality are improved simultaneously. Through the composite pretreatment process, the synergistic effect is realized, the selenium content of the finished product is greater than or equal to 0.5 mg / kg, the GI value is less than or equal to 55, the selenium bioavailability is greater than or equal to 65%, the breakage rate is 0%, the cooking loss is less than or equal to 6.7%, the rehydration rate is about 125%, the color is white and uniform, and no visible impurities are observed; the total drying time is shorter than that of the prior art, the method is suitable for industrial grinding production system, and the nutritional health, food quality and production efficiency are considered.

This invention belongs to the field of animal husbandry and deep processing of agricultural products, specifically relating to a method and its application for cultivating low-cadmium, selenium-rich mealworms using cadmium-containing feed. Specifically, this invention involves adding a low concentration of selenium to a cadmium-containing bran and rice bran feed to raise 3rd-4th instar mealworms. In the later stages of rearing, the mealworms are transferred to a selenium-only feed for cadmium removal, ensuring that the cadmium content in the mealworms does not exceed relevant standards and achieving the goal of efficiently treating cadmium-containing agricultural waste and obtaining low-cadmium, selenium-rich mealworm products. Finally, lipids in the mealworm powder are extracted in one step using low-boiling-point petroleum ether to obtain low-cadmium, selenium-rich mealworm protein powder. In summary, this invention is simple, low-cost, and can efficiently process cadmium-containing materials while simultaneously yielding low-cadmium, selenium-rich, high-quality mealworm products and mealworm protein powder, without affecting mealworm yield. It achieves multiple benefits and has good practical application value.
