KINTAI produces SME from high quality shiitake mushroom (scientific name: Lentinula edodes), which is a fungus with rich nutritional and medicinal values. The following is our raw material collection process:
1.Variety selection: We select shiitake mushrooms with good quality and good growth pattern as raw materials. Varieties with high yield and high content of active ingredients are carefully selected to ensure the quality and efficacy of the final product.
2.Growing environment: We carefully create a suitable growing environment, shiitake mushrooms usually grow in a moderate temperature and humidity environment with good ventilation. We control the temperature, humidity and air flow to provide the best growing conditions for shiitake mushrooms.
3.Pollution-free cultivation: We strictly follow the principles of no pesticides, no heavy metals and no pollutants in our cultivation. We ensure the quality of soil and water sources to avoid contamination of shiitake mushrooms by harmful substances.
4.Timing of picking: During the growth of shiitake mushrooms, we choose the appropriate time for picking according to their physiological characteristics and optimal maturity period. This ensures the freshness of the shiitake mushroom and the content of its active ingredients.
5.Extraction process: After picking, we process the shiitake mushroom initially, remove impurities and chop it. Then, using modern technology extraction process, we extract the active ingredients from the shiitake mushroom to get the pure SME.
6.QC and Quality Control: Throughout the production process, we strictly enforce quality control standards to ensure that our products meet international quality requirements. Each batch of SME is subjected to a number of tests, including the content of active ingredients and microbial safety.
