Chinese also known as: Pleurotus ostreatus English: Pleurotus ostreatus Pleurotus ostreatus is rich in nutrients, containing 20-23 grams of protein per 100 grams of food, and has a complete variety of amino acids and rich mineral content. Mushrooms can form complete active ingredients only when they grow into fruiting bodies. Therefore, we prefer Pleurotus ostreatus fruiting bodies as the extraction material to eliminate common quality problems such as heavy metals and excessive pesticide residues in the raw materials. More than ten years of mushroom extraction and production experience has enabled us It is possible to achieve extract products with low or even no auxiliary materials to the greatest extent. In the raw material extraction process, we are different from the traditional direct feeding method. We pass the raw materials through the unique raw material breaking technology to maximize the release of active ingredients. Compared with similar products in the market, the polysaccharide content is increased by 5-10%. At the same time, the pre-processing of materials also increases the yield of the final product. It seems that the process is cumbersome and the process is increased. In fact, it reduces the cost and improves the product quality.
