Production Process
Reishi production is more than harvesting and drying. It requires deep expertise and precise craftsmanship. Through 50 years of practice, Sungertain has continuously refined every step, ensuring every stage from strain cultivation through to the final product remains traceable and independently verifiable.
Process Overview
From strain preparation and substrate bag cultivation to the final product, this section walks through each stage of the process and explains quality testing, sustainability, and common questions.
Phase 1
Establishing the right strain source and vitality creates a stable foundation for every subsequent stage.
Step 1
Sungertain strains come from carefully selected mother cultures. Each generation is purified and screened to ensure genetic stability, growth speed, and polysaccharide levels.
Step 2
Selected mother cultures are multiplied in a sterile environment using laminar flow benches and autoclaves to reduce contamination risk.
Phase 2
Standardising the substrate, filling, sterilisation, and inoculation process so the mycelium can fully colonise in a controlled environment.
Step 3
Sawdust, wheat bran, gypsum, sugars, and water are balanced in precise ratios to create a nutrient medium that steadily supports mycelial growth.
Step 4
The prepared substrate is filled into bags at a standard weight and density, then heat-sealed to keep the specification consistent.
Step 5
Filled bags are autoclaved at 121°C and 15 psi to eliminate contaminants and pathogens.
Step 6
After cooling, the bags are inoculated on a sterile bench to minimise contamination and keep the spawn pure.
Step 7
Inoculated bags move into a spawn-run room where constant temperature, humidity, and darkness support full colonisation.
Phase 3
Once colonisation is complete, environmental changes trigger fruiting body formation, and harvest timing is set by the best maturity indicators.
Step 8
Temperature, humidity, light, and airflow are adjusted to shift the mycelium into reproductive growth and form primordia and fruiting bodies.
Step 9
Primordia, young fruiting bodies, growth, and maturation progress in sequence while the fruiting body gradually accumulates polysaccharides, triterpenoids, and other active compounds.
Step 10
Harvest decisions are based on edge thickness, colour, weight, and spore maturity to avoid picking too early or too late.
Phase 4
Post-harvest handling directly affects shelf life and bioavailability. Every step is kept at low temperature, clean, and traceable.
Step 11
Soft brushes and cloths are used to clean away surface substrate and spores, then the material is graded by appearance, integrity, and defects.
Step 12
Staged drying at 45-70°C keeps moisture below 12% while minimising heat damage to polysaccharides and triterpenoids.
Step 13
Ultrasonic cell wall disruption and mild enzymatic hydrolysis improve absorption while keeping the active compounds ready for later processing.
Step 14
Hot-water or alcohol extraction is used when needed to concentrate the active compounds while keeping temperature controlled so activity does not drop.
Step 15
Depending on the intended use, reishi is processed into powders, capsules, tablets, or beverages so the product can fit naturally into everyday life.
Quality Control
Quality is not a single inspection point. It is a traceable and verifiable process covering strains, raw materials, intermediates, and finished products.
SGS Reports
Publicly display test certificates for different products and raw materials so visitors can review batch transparency and safety information directly.
Sustainability
Production is not judged by the finished product alone; it also considers whether waste, water, energy, and the surrounding ecosystem can remain in balance over time.
After harvest, the used bags and substrate are composted and returned to the soil cycle.
Natural spring water from the Shiding mountains is used efficiently, and wastewater is biologically treated before discharge.
Solar-assisted heating is introduced in the drying rooms, while energy use continues to be optimised across each production stage.
Native trees and ecological buffer zones are preserved around the farm to support natural pest control and stable habitats.
FAQ
We have grouped the most common questions about production time, quality verification, product pairing, and storage conditions to make the page easier to understand.
From strain preparation, spawn run, and fruiting to drying and processing, the full cycle usually takes 4-6 months. These steps cannot be compressed without sacrificing quality.
You can assess appearance, aroma, texture, and solubility, and you can also review test reports for pesticide residues, heavy metals, polysaccharides, and safety.
It can be paired with astragalus, red dates, honey, and similar ingredients, but the combination should be adjusted according to the intended use and setting. Product pages will guide visitors to the most suitable format.
Store them in a cool, dry place away from direct sunlight and high humidity. Powders, capsules, and beverages may have different storage requirements, so follow the product label.
