Our Process

Primary medium : Sawdust
Supplemented medium : corn cobs, Kelp meal & various brans
Key point : Fresh medium is essential

Mechanically mixing and watering substrates in a large revolving mixing container
Key point : Achieve even mixture of ingredients with a desired level of moisture (60 – 67%)

Mixed and moistened substrates are filled into heat resistant polypropylene bottles with a capacity of 1,100ml, then five holes are punched in the filled bottles, and bottles are covered with plastic lid.
Key point : Unform amounts of the mixed substrates are filled in each bottle.

The substrate is sterilized with air steam at 100 ~121ºC in high pressure auto clave.
Key point : Complete pasteurization is essential to kill unwanted competitive micro organisms.

The pasteurized substrate is cooled down to 20ºC to achieve optimal condition for spawning.
Key point : Keep cooling room condition clean at
CLASS 5,000 maintaining positive air pressure.

The substrate is inoculated with the optimal amount of liquid spawn by automatic inoculation equipment, so as to reduce contamination risk.
Key point : Keep room condition clean at CLASS 1,000, maintaining positive air pressure.

Production and maintenance of pure mycelial cultures is a necessity to ultimate spawn preparation and spawn production.
Key point : To produce a desirable mycelial culture, pure and free of contaminants and of sectoring of other abnormalities is the most critical factor.

After the mycelium is allowed to colonize the substrate (spawn run), the desired level of environment conditions are maintained for about 25 to 35 days in dark incubating room.
Temperature : 20 – 23ºC
Humidity : 60% – 70%
CO2 : 800 – 3,000ppm
Key points : Temperature, light intensity and relative humidity interact each other influencing the nature and quality of mycelial growth.

After the substrate is fully colonized, the original inoculum is removed mechanically from the surface of the substrate and the bottles are placed upside down for a few days.
Key points : Any contaminated bottles are thoroughly screened during the scratching process.

After removal of original inoculum by scratching, the top surface (substrate) is exposed to conditions favorable for primordial formation for 10 to 12 days.
Temperature : 20 – 23ºC
Humidity : 60-70%
CO2 : 800 – 3,000ppm
Key points : To stimulate primordium maturation, a delicate environment condition should be provided.

After primordial formation, if optimum fruiting environment is maintained, the mushrooms begin to elongate above the lip of the bottle.
Key point : To further improve quality during fruiting, temperature is maintained at lower (11 – 13ºC) until harvest.

When mushrooms are mature to be 13 – 14cm long, the entire cluster of fruiting bodies are pulled as a bunch from the substrate.
Key point : In order to obtain high quality freshness, harvest the mushroom before they are fully matured.

The mushrooms are placed into trays, bags and boxes and packed properly for shipping to the market.
Key point : Packing process should be kept clean always.

After only one flush of mushrooms is harvested, ” spent mushroom substrate ” is removed from bottles. The bottles are cleaned by pressurized air. The cleaned bottles are used for refilling the fresh substrate and the process is repeated.
Key points : Bottle cleaning area should be kept clean always.
