However, the test results show that more than 15% of the chromium in the chromium-enriched yeast still exists in the form of inorganic chromium, and there is still a certain safety risk if a large amount of such products are consumed

Embodiment 3

[0050] The preparation method of organic chromium-rich barley worm powder comprises the following steps:

[0051] 1) Cleaning: After the organic chromium-rich barley worm larvae cultured in Example 1 were graded and screened according to body length (they were classified into two grades of 10-12cm and 12-15cm according to body length, so as to facilitate the subsequent freeze-drying step), different Grade live worms are washed with deionized water at 90°C for 3 minutes to remove dirt and prevent barley larvae from crawling;

[0052] 2) Freeze-drying: Lay the cleaned organic chromium-rich barley larvae on a tray (20-40cm in diameter) according to the thickness of 3cm, and then freeze at -20°C for 1 hour, then take it out and put it into freeze-drying Freeze and dehydrate in the machine for 24 hours. The water content of the barley worm larvae after drying and dehydration is 4%, and they are sealed in plastic sealed bags and stored at a temperature of 0°C;

Abstract

The invention relates to a superworm powder rich in organic chromium, and a preparation method thereof. The content of organic trivalent chromium in the superworm powder rich in organic chromium is 10-200mg / kg. The preparation method of the superworm powder comprises the following steps: cleaning superworm larvae rich in organic chromium with deionized water, lyophilizing, carrying out low temperature squeezing, crushing, and carrying out ultramicro crushing. The superworm powder prepared in the invention well reserves the conformation of organic complex chromium, is rich in nutrients comprising free amino acids, water-soluble proteins, chitins and the like, and has a low protein denaturation degree, the granularity of crushed nutrients is extremely small, so it is benefit for the digestion and absorption; and the superworm powder has a low fat content, so the superworm powder has substantial healthcare effects on special people comprising fat people, diabetic patients and the like.

Description

technical field [0001] The invention relates to a barley worm powder and a preparation method thereof, in particular to an organic chromium-rich barley worm powder and a preparation method thereof. Background technique [0002] Chromium (Ⅲ) is one of the important trace elements in the human body and has the function of lowering blood sugar. When the body is deficient in chromium, the level of insulin decreases, which induces disorders of glucose metabolism and lipid metabolism. Studies have found that chromium supplementation can enhance insulin sensitivity, regulate glucose metabolism and lipid metabolism. Trivalent chromium ion is the active ingredient of glucose tolerance factor (GTF, Glucose Tolerance Factor). GTF is a substance with nicotinic acid-trivalent chromium-niacin as the axis and glutamic acid, glycine and cysteine ​​as the ligands. Pure chromium ions have no biological activity, and almost all chromium in animals is trivalent chromium, but its function of ...
