preparation example Construction

[0023] Concrete preparation method comprises the following steps:

[0024] (1) krill with a selenium content of 3-50 micrograms per gram as raw material;

[0025] (2) Superfine pulverization to make krill nanometer or after shelling, perform superfine pulverization to make krill nanometer;

[0026] (3) Proportioning is prepared into additives with different selenium content.

[0027] The above-mentioned superfine pulverization can be pulverized by a fluidized bed jet pulverizer or superfine pulverizer, and a laser particle size analyzer can be used to monitor the pulverization process, and the average particle size of pulverized krill particles is controlled to be 0.5-10.0 microns.

Embodiment 1

[0029] The krill with a selenium content of about 3-50 micrograms per gram is crushed with a QYF-600 fluidized bed jet mill of the Miyou Group, and a laser particle size analyzer is used to monitor the crushing process, so that the average particle size of the krill particles is 0.5-10.0 microns. At the same time, more than 10% of the krill particles reached the nanometer level.

Embodiment 2

[0031] Krill with a selenium content of about 50 μg / g, after shelling (remove krill shells with high fluorine content to prevent exceeding the fluorine limit requirements of food additives), use an ultrafine pulverizer for ultrafine pulverization, during the pulverization process The laser particle size analyzer is used to monitor, so that the average particle size of the krill particles is 0.5-1.0 micron, and at the same time, 40%-50% of the krill particles reach the nanometer level.

Abstract

The invention discloses a method for preparing an animal organic selenium-rich additive. The method comprises the following step of: performing ultra-micro crushing and nano treatment on freeze-dried krill serving as a raw material. In the ultra-micro process, the crushing degree can be monitored by using a laser granularity instrument to control the diameter of the granules obtained by crushing. The invention also provides the animal organic selenium-rich additive prepared by the method, wherein the additive can be used for preparing selenium-rich food or selenium-rich feed. Because the selenium in the additive is from natural seafood, namely krill, the additive has the characteristics of safety, non-toxicity and good effect by combining a nano technology. The selenium-rich food prepared by using the organic selenium-rich additive provided by the invention can improve the selenium intake of a common person to 50 to 250 micrograms every day, so the incidence rate of chronic diseases related with heart and brain blood vessels and partial cancers is greatly reduced; and the selenium intake of chronic disease, low-immunity or cancer patients is improved to 200 to 800 micrograms every day.

Description

technical field [0001] The invention relates to a method for preparing an additive rich in animal organic selenium, the additive and its application, and relates to the field of food and / or feed additives. Background technique [0002] Krill (Euphausia) is a marine organism with high selenium content, and the selenium concentration is 0.5-50 μg / g. Marine organisms, such as selenoproteins and other macromolecular nutrients contained in krill, can accelerate the decomposition of oxides in the human body, prevent tumors, reduce radiation damage, and reduce the side effects of chemotherapy for cancer patients. There are about 80 species of krill in the world, which are rich in phosphorus and protein; the body shape is like a small shrimp; the length is 1-2 cm, the largest species is about 5 cm; the abdomen has 6 segments, and the end has a telson; 8 pairs of thoracic limbs, all It is a double-branch type; each base has gills, suitable for swimming, planktonic life, and all seaf...
