Introduction to the Source Plant of Pleurotus Ostreatus Extract: Its Distribution and Growing Environment

Pleurotus ostreatus, commonly known as the oyster mushroom, is a widely consumed fungus and one of the main sources for Pleurotus ostreatus extract. Below is an overview of the plant’s source, distribution, and growing environment.

Source Plant Overview:

Pleurotus ostreatus, also known as oyster mushroom or abalone mushroom, belongs to the kingdom Fungi, order Agaricales, family Pleurotaceae. It features a fan-shaped cap, soft flesh, white gills that are attached to the stem in clusters, and a short, laterally growing stem, often shaped like a fan or semicircle with firm flesh.

Distribution:

Oyster mushrooms are widely distributed, primarily found in temperate and subtropical regions, especially across the northern hemisphere. They thrive in various environments, including forests, grasslands, edges near trees, marshlands, open woodlands, and decaying wood piles or tree stumps.

Growing Environment:

  1. Temperature Requirements: Optimal growing temperatures range from 15°C to 25°C, with the ideal being around 20°C. Extreme temperatures can negatively impact growth and yield.
  2. Humidity Requirements: They thrive in high humidity, preferably between 60% and 70%. Adequate moisture supports mycelial growth and fruiting body formation, but excessive humidity may encourage pathogen growth.
  3. Light Requirements: Oyster mushrooms are neutral light fungi; they prefer shaded or low-light conditions. Direct sunlight can dry out the mycelium and hinder growth.
  4. Soil Texture: The soil should be rich in organic material, well-draining, with a pH level between 6.5 and 7.5. Soil that is too hard or too loose is detrimental to growth.
  5. Climate Conditions: Highly adaptable, oyster mushrooms can thrive in various climate conditions; however, they do not perform well in dry or excessively cold environments.

In conclusion, Pleurotus ostreatus is a common fungus that is widely distributed in temperate and subtropical regions, with relatively flexible growing environment requirements, showcasing strong adaptability. Understanding these growth conditions is crucial for effective cultivation and production.

Processing and Storage of Pleurotus Ostreatus Extract

The processing of Pleurotus ostreatus extract typically includes the following steps: first, fresh mushrooms are harvested, cleaned, and ground into powder or sliced. Then, appropriate solvents (such as water or ethanol) are employed to extract the mushroom, yielding an extraction liquid. Following this, the liquid undergoes processes like filtration, concentration, and drying to produce a powdered form of Pleurotus ostreatus extract. Finally, quality checks are performed, and the product is sealed for storage.

For storage, Pleurotus ostreatus extract should be kept in a cool, dry, and well-ventilated environment away from direct sunlight and high humidity. It's crucial to protect it from moisture to prevent spoilage. It is advisable to store the extract in sealed containers to minimize exposure to air to extend its shelf life. If any clumping or unusual odors arise, usage should be discontinued immediately.
