Abstract
A detailed sample evaluation report is critical in the sourcing and quality validation process for Ganoderma lucidum (Lingzhi) extracts. This document ensures that buyers, regulatory reviewers, and internal stakeholders understand the functional quality, safety, and commercial viability of a Reishi mushroom extract sample. This article outlines the core components such a report must include to meet professional and international standards.

Introduction

When selecting a new Ganoderma extract supplier or verifying a new product batch, a comprehensive sample evaluation report acts as both a technical and compliance roadmap. Whether for nutraceuticals, functional foods, or cosmetics, this report helps stakeholders confirm that the sample aligns with the intended product requirements and regulatory benchmarks. The following sections describe the critical content a well-prepared Lingzhi extract evaluation report should provide.

1. Product Identification and Specification

Details should include:

• Common name: Reishi Mushroom / Lingzhi

• Botanical name: Ganoderma lucidum

• Product type: Extract powder / liquid / spore oil

• Appearance: Color, texture, solubility

• Product code / batch number

Including a product photograph and certificate ID helps prevent mislabeling or confusion across SKUs.

2. Active Ingredient Content and Standardization

Quantification of core bioactive markers is central:

• Polysaccharides (e.g., 20–30% w/w)

• Triterpenoids (e.g., 2–5% w/w)

• Ganoderic acids (specific quantification via HPLC)

A high-quality Ganoderma lucidum extract report includes the method of testing (e.g., UV-Vis spectrophotometry, HPLC), units (%, ppm), and acceptable tolerances. Standardization ensures consistent therapeutic efficacy.

3. Analytical Testing Results

A critical section that validates the sample’s safety and compliance.

Key parameters include:

• Moisture content: <7% (ensures shelf stability)

• Ash content: <5% (limits non-organic residues)

• Heavy metals (Pb, Cd, Hg, As): must meet WHO/USP limits

• Pesticide residues: Particularly for organic Lingzhi extract

• Residual solvents: Ethanol, methanol levels for extracts

• Microbial limits: Total plate count, E. coli, Salmonella

Testing should be performed by certified third-party labs or in-house ISO/IEC 17025-accredited facilities.

4. Solubility and Sensory Properties

For beverage or food applications, solubility in water (cold or hot) and flavor profile are essential. Reports should note:

• Solubility rate (%)

• Particle size (e.g., mesh count)

• Taste, aroma, and bitterness evaluation (subjective but valuable)

For example, a Reishi mushroom extract intended for instant tea should have >95% cold-water solubility and minimal sediment.

5. Certificate of Analysis (COA)

The COA is a core part of the report and must be current and batch-specific.

Should include:

• All lab results

• Testing methods used

• Date of testing

• Lab accreditation and analyst signature

Some clients may require COAs to align with U.S. Pharmacopeia (USP), European Pharmacopoeia (EP), or Chinese Pharmacopoeia (ChP) specifications.

6. Stability and Shelf Life Data

This section ensures the Ganoderma extract maintains integrity over time. It should cover:

• Real-time stability (6–12 months recommended)

• Accelerated stability testing (e.g., 40°C/75% RH)

• Recommended storage conditions

• Shelf life projection (typically 24–36 months for powders)

7. Application and Use Recommendations

Depending on the client’s needs, the report can include:

• Suggested dosage ranges (mg/day or per serving)

• Suitable delivery forms (capsules, beverages, cosmetics)

• Compatibility with other ingredients or carriers

Some suppliers offer this section as a “formulation guide” for brand owners.

8. Regulatory and Certification Information

This includes a summary of the extract’s compliance with:

• Organic certifications (e.g., USDA, EU Organic)

• Kosher / Halal certifications

• Non-GMO and allergen-free statements

• GACP/GMP facility status

This helps clients assess the extract’s fit within their product and market strategy.

9. Sample Evaluation Summary and Scorecard

A summary table or scorecard is useful for quick client decisions:

Conclusion

A well-prepared evaluation report for Ganoderma extract samples ensures transparency, safety, and suitability for a wide range of product applications. By including comprehensive test results, functional data, and regulatory certifications, suppliers not only build client trust but also streamline the qualification and procurement process for Ganoderma lucidum extract.
