GreenFood Nutrition Beta Glucan 90 capsules

The oyster mushroom is a popular mushroom known for its characteristic appearance and taste. Oyster mushrooms have been popular and widely used for thousands of years in China due to their high content of Beta-glucans. It grows naturally on wood, often on tree stumps and trunks. The cold process helps to preserve the bioactive properties of beta glucans because there is no thermal damage to the molecules. The gentle extraction process ensures high purity of the final product, which is important for its quality and effectiveness. Cold-extracted beta glucans retain their solubility and stability. Beta glucans are natural polysaccharides composed of glucose molecules. They are one of the main structural components of the cell walls of fungi, cereals, yeasts and some bacteria. Beta glucans differ in their molecular structure, which affects their biological properties and use in the food and pharmaceutical industries.

The process of growing oyster mushrooms

The mushroom is valued not only for its culinary properties, but also for its nutritional and bioactive content, including beta glucans. Oyster mushrooms are grown on cellulose-rich substrates such as wood chips or straw. The cultivation process is controlled to ensure the high quality and purity of the mushrooms. After harvesting, the oyster mushroom is dried at low temperatures to reduce the water content and preserve the bioactive components, facilitating the subsequent extraction of beta glucans. Heat breaks down beta glucans. The dried mushrooms are ground into a fine powder, which is then subjected to an extraction process. Usually, aqueous or ethanol extraction methods are used to isolate beta glucans from fungal cell walls. The extract is then filtered and concentrated to obtain pure beta glucan. Pure beta glucan is dried by spray drying or freeze drying, which provides a stable and easy to use powder.
