The production practice in recent years has proved that the high-end magnesium carbonate project of Hebei Messi Biology Co., Ltd. is scientific and reasonable, with strong practicality and operability, stable production system operation, accurate and reliable automatic control, and stable product quality indicators. After a large number of sampling tests in daily production, all brands of food-grade magnesium carbonate products produced by the company are strictly tested according to the prescribed standard test methods. Their physical and chemical performance quality indicators have met the design requirements. The application performance quality indicators of the products have been tested by different quality inspection agencies and some customers have been applied in practice, and the reflection is good, which is completely comparable to international well-known brands of the same kind.
The overall quality level of food-grade magnesium carbonate products of Hebei Messi Biology Co., Ltd. is better than that of domestic peers, and the main basic quality indicators have reached or even exceeded the quality level of international first-class products. In particular, the quality indicators of product stability, content, whiteness, etc. are completely up to or slightly better than those of international well-known brands, and the products of different months and batches have maintained a very stable quality level. After inspection of impurities and harmful elements in the products by foreign testing agencies, the content of heavy metals such as lead, arsenic, chromium, mercury, hydrochloric acid insolubles, sulfates, chlorides and other toxic and harmful substances in the products is low or even zero, which meets the requirements of European and American indicators. It has been recognized by domestic and foreign companies and is another fruitful result of the scientific and technological innovation of Messi Biology. It fills the gap in the application of magnesium carbonate in food in China and plays a positive role in enhancing product differentiation competition and promoting enterprise transformation and upgrading.
After multiple batches of testing and use by different industries and users, it is generally believed that the main physical and chemical indicators and application indicators of food-grade magnesium carbonate products of Hebei Messi Biology Co., Ltd., including content, heavy metals, whiteness, particle size, etc., can meet the application requirements. Among them, the product dispersibility, hiding power and whiteness are better than similar domestic products, and are basically the same as or even slightly better than well-known foreign products such as Israel and Japan. It can completely replace imported high-end magnesium carbonate products in general application fields.
