Product Overview

Our Wheat Germ Extract is a premium, plant-derived polyamine source extracted strictly from the germ of Triticum aestivum (non-GMO). Unlike synthetic alternatives (Spermidine 3HCl), which offer a single isolated compound, this extract provides Spermidine within its natural whole-food matrix, supporting clean-label positioning for cellular health and longevity formulations.

The defining characteristic of this ingredient is its validated potency. While many market alternatives utilize non-specific UV testing methods that can yield false positives from other nitrogenous compounds, we standardize our extract to ≥0.2% Spermidine using gas chromatography (GC). This ensures that the bioactive content is authentic, specific, and traceable.

Produced in a GMP-compliant environment, the powder exhibits excellent physical stability with moisture levels significantly below industry limits (2.45% vs standard ≤7%). This low water activity makes it highly compatible with moisture-sensitive ingredients in complex blends, such as probiotics or hygroscopic vitamins.

Unique Product Advantages:

• Authentic Natural Source: Derived 100% from Triticum aestivum germ; free from synthetic adulterants.
• GC-Verified Potency: Assay guaranteed ≥0.2% by Gas Chromatography (GC), offering superior specificity compared to UV methods.
• High Stability Profile: Measured loss on drying of 2.45% (batch BH250120CH) ensures long-term stability and reduced risk of caking.
• Strict Safety Control: Heavy metals are rigorously controlled (Pb <2ppm, As <2ppm) with a negative pathogen profile, exceeding standard food-grade requirements.
• Manufacturer Direct: Full batch traceability and consistent supply available directly from the origin factory.

Key Technical Specifications

The following specifications represent the typical analysis of our Wheat Germ Extract (Batch Ref: BH250120CH). This natural extract represents a balance of bioactive potency and physical purity.

Physical Characterization & Processing Suitability

For formulators assessing processability, we provide a deeper look into the physical characteristics based on the current batch data:

Density & Flow Profile With a Bulk Density of 0.52 g/cm³ and Tapped Density of 0.83 g/cm³, the powder exhibits a Hausner Ratio of approximately 1.60. This indicates a cohesive powder, which is typical of natural wheat germ extracts containing residual lipids.

• Processing Recommendation: While the powder shows excellent compressibility for tablet hardness, we recommend the addition of glidants (e.g., 0.5–1% Silicon Dioxide) to improve flowability during high-speed capsule filling or tableting operations.

Moisture Control The measured Loss on Drying (LOD) is 2.45%, significantly lower than the standard limit of 7%. This low moisture content provides exceptional stability, minimizing the risk of hydrolysis or microbial growth. It ensures compatibility with moisture-sensitive ingredients in complex formulations.

Particle Uniformity The specification of 100% passing 80 mesh ensures a fine, consistent particle size. This facilitates homogeneous blending with other fine powders (such as Vitamin premixes or Zinc) without the need for additional milling steps.

Quality Control: Why GC Testing Matters

In the market of polyamines, the testing method defines the authenticity of the product.

• The GC Advantage (Gas Chromatography): We utilize GC analysis to specifically separate and quantify the Spermidine molecule.
• The Risk of UV: Many generic suppliers use UV spectrophotometry. However, UV is non-specific and can detect other nitrogen-containing compounds or proteins in wheat germ as “Spermidine,” leading to inflated, false-positive results.
• Our Commitment: By adhering to GC testing, we ensure that the ≥0.2% claim represents true bioactive Spermidine content, providing reliable dosage calculations for your finished product.

Formulation & Application Guidelines

Designed for versatility, our Wheat Germ Extract (0.2% Spermidine) is optimized for dietary supplement formats. Below are specific formulation data points to assist in your product development.

Dosage Calculations & Delivery Systems

• The “1mg” Target: To achieve a label claim of 1mg Spermidine per serving, a dosage of 500mg of this extract is required.
  • Calculation: 1mg(Target) / 0.002(Assay) = 500mg.
• Capsule Fitment Analysis: Based on the Tapped Density of 0.83 g/cm³, a 500mg dose occupies approximately 0.60 ml of volume.
  • Size 0 Capsule (Vol ~0.68ml): Fits comfortably with minimal headspace (approx. 88% fill rate), ideal for a pure standalone product.
  • Size 00 Capsule (Vol ~0.95ml): Leaves ample space for blending with synergistic ingredients like Zinc, Magnesium, or B-Complex vitamins.
• Tablet Compressibility: The extract’s density profile suggests good compressibility. However, given the natural lipid content of wheat germ, we recommend using a higher compression force and appropriate binders to ensure tablet hardness and disintegration time compliance.

Recommended Blends

• Cellular Health Complex: Combine with Resveratrol or Quercetin to create a multi-pathway longevity formula.
• Immune Support: The extract pairs well with Zinc (a co-factor for cell division) and Vitamin D3.

Stability & Storage

• Storage Conditions: Store in a cool, dry place away from strong light and heat. The low moisture content (2.45%) provides excellent intrinsic stability, but the product should be kept in its original packaging to prevent hygroscopicity.
• Shelf Life: 24 months under properly stored conditions.
• Stability Data: The extract maintains Spermidine integrity in pH ranges of 3.0–8.0, making it suitable for most solid dosage forms and select functional beverage powders.

Frequently Asked Questions (FAQs)

Q: Is this Spermidine natural or synthetic?

A: This is a 100% natural extract derived from the germ of Triticum aestivum. Unlike synthetic Spermidine Trihydrochloride (3HCl), our product retains the natural whole-food matrix of the wheat germ.

Q: Does this product contain Gluten?

A: Yes, as a wheat-derived ingredient, it naturally contains gluten. It is typically used in dietary supplements where “Wheat” is declared as an allergen. For specific “gluten-free” requirements, please contact our technical team for batch-specific processing details.

Q: What is the difference between UV and GC testing for Spermidine?

A: UV methods detect total nitrogenous compounds and can result in false positives (reading higher than actual). We use Gas Chromatography (GC) to separate and quantify the specific Spermidine molecule, ensuring you get exactly what you pay for.

Q: Do you supply directly from the factory?

A: Yes, we are the manufacturer. Sourcing directly ensures full batch traceability, fresher stock (Manufacture Date: Jan 2025 for current batch), and competitive factory-gate pricing.

Q: What is the standard packaging?

A: The product is packed in 25kg Fiber Drums with double-layer PE inner bags to ensure protection against moisture and contamination during transport.
