preparation example Construction

[0027] The application utilizes secondary biotransformation technology, which can provide safe and reliable selenium-enriched Tenebrio molitor powder with a very low proportion of inorganic selenium. One embodiment is, as figure 1 Shown is a preparation method of selenium-enriched Tenebrio molitor powder, which includes the following steps: adopting a selenium-enriched production method to produce selenium-enriched feed; using the selenium-enriched feed to feed Tenebrio molitor; using Tenebrio molitor to dry and make powder. The above preparation method first produces selenium-enriched feed, then produces selenium-enriched Tenebrio molitor and then dries and makes powder. On the one hand, the selenium-enriched feed undergoes a conversion of inorganic selenium into organic selenium, and on the other hand, the selenium-enriched mealworm undergoes another conversion of inorganic selenium into organic selenium. Selenium, equivalent to the secondary transformation of inorganic selen...

Embodiment 1

[0039] Embodiment 1: Selenium-enriched feed is produced by selenium-enriched production mode; Tenebrio molitor is fed by the selenium-enriched feed; Tenebrio molitor is used for drying and milling. Wherein, the selenium-enriched feed includes bran with a selenium content exceeding 4 mg / kg, wherein the proportion of organic selenium exceeds 85%; a certain proportion of common feed such as fine powder (such as corn flour, etc.), vegetable leaves, melons and fruits is also added during feeding. Skin, etc., and some conventional chemicals; but the proportion of selenium-enriched feed is about 65% to 75%. Among them, the larvae of Tenebrio molitor with a age of 35 to 40 days are used for drying and milling.

Embodiment 2

[0040] Embodiment 2: Different from Embodiment 1, the larvae of Tenebrio molitor with a age of 41 to 46 days are used for drying and milling.

Abstract

The invention relates to a preparing method of selenium-rich flour weevil powder and a selenium-rich flour weevil powder product. The method includes the following steps of producing a selenium-rich feed through a selenium-rich production mode, feeding flour weevil with the selenium-rich feed, and drying the flour weevil to prepare the powder. By means of the preparing method, the selenium-rich feed is produced first, and then the selenium-rich flour weevil is produced and then dried to prepare the powder; on one hand, inorganic selenium of the selenium-rich feed is converted into organic selenium for the first time; on the other hand, the inorganic selenium is converted into the organic selenium by the flour weevil for the second time, and equivalently the inorganic selenium is convertedtwice; thus, the ratio of the inorganic selenium in the selenium content of the prepared powder is greatly reduced, the powder is safe and free of toxin to human bodies, and the product can have the higher selenium content.

Description

technical field [0001] The application relates to the field of selenium-enriched Tenebrio molitor, in particular to a preparation method of selenium-enriched Tenebrio molitor powder and a product of selenium-enriched Tenebrio molitor powder. Background technique [0002] Tenebrio molitor, also known as mealworm, belongs to Coleoptera, Pedidae, and Meal beetle (Pedidae) in insect taxonomy. Native to North America, it was introduced to China from the Soviet Union in the 1950s. The longest adult lifespan is 196 days, with an average of about 51 days; it eats drum skin, soybean powder, vegetable leaves, melon skin, fruit peel, etc. Tenebrio molitor has been widely cultivated in China, and the technology is mature. [0003] Tenebrio molitor dry product contains 30% fat and more than 50% protein. In addition, it also contains phosphorus, potassium, iron, sodium, aluminum and other macro elements and various trace elements. Because dried Tenebrio molitor larvae contain about 40%...
