Product Overview

What Is Coix Seed Powder?

Using current methods to process this old Asian grain from Coix lacryma-jobi var. ma-yuen (Job's Tears) keeps a lot of its nutrients.

Why they're not like others:

• Standardised potency: 98% coixenolide is ensured, compared to 0.3% to 0.5% in raw grains
• Improved bioavailability: nanoparticles that are sprayed dry are taken four times better than powders that are ground.

Manufacturing Process: From Seed to Extract

Step 1: Raw Material Qualification

• Source from GAP-certified farms in Guizhou/Yunnan provinces
• Incoming inspection: Moisture, impurities, coixenolide pre-screening
• Cold storage at 5-10°C to prevent enzymatic degradation

Step 2: Zero-Sulfur Cleaning

Unlike traditional sulfur fumigation (banned in EU/US supplements), we use:

• Mechanical destoning and air classification
• Ozone treatment for microbial reduction
• Cold plasma surface sterilization

Step 3: Low-Temperature Extraction

• 50°C vacuum drying (vs. 80-120°C in standard processing)
• Cryogenic milling at -20°C prevents lipid oxidation
• Nitrogen blanketing throughout process

Step 4: Spray Drying (Patented Nozzle Design)

• Inlet temperature: 140-160°C (outlet: 60-80°C)
• Achieves <5% moisture in single pass
• Creates 10-50μm particles for optimal dissolution

Step 5: Quality Verification

Every batch undergoes 47-point inspection:

• Identity testing
• Contaminant screening (heavy metals, pesticides, mycotoxins)
• Stability testing

Step 6: Packaging

• Food-grade LDPE bags (UV-blocking)
• Aluminum foil outer layer (oxygen barrier)
• Oxygen absorbers + nitrogen flush
• Tamper-evident seals

Quality Documentation Provided:

• Certificate of Analysis (COA)
• MSDS / SDS
• Allergen declaration

FAQ

Q: Does your 98% coixenolide extract compare to entire coix seed flour?

A: Whole flour has 0.3-0.5% coixenolide. Our extract concentrates this 200-fold, enabling 1/200th the dosage for bioactivity. This lowers formulation costs and promotes customer compliance (smaller capsules, less powder flavour).

Q: Does this replace barley or oat flour in gluten-free baking?

A: Its particular protein/starch ratio makes it suitable as a 10-30% replacement. Our food experts can advise on hydration and binding agents for complete formulation assistance (100kg+ orders).

Q: How do you prevent rancidity given the natural oil content?

A: Three layers of defence:

• Process using mixed tocopherols (natural vitamin E).
• Packaging that flushes nitrogen eliminates oxygen
• Place under cool (<25°C) circumstances.
• Peroxide value remains <5 meq/kg for 24 months (vs. industry limit of 10).

Q: Do you test glyphosate?

A: We evaluate 15 herbicide residues, including glyphosate, glufosinate, and paraquat. Our normal values are <0.01ppm (100x below EU MRL).

Q: Are there payment conditions or full prepayment?

A: First orders:

• 50% deposit, 50% before shipping (T/T or PayPal for <$5,000).
• Net 30 terms with credit application for established clients (3+ orders).

Q: Can you help with formulation if we've never used this ingredient?

A: Yes, our application engineers offer:

• Product type-specific use guidelines
• Testing your other components for compatibility
• Advanced ageing guiding stability methods

This is free for 50kg+ purchases.

Q: Do you contract manufacture finished products?

A: OEM/ODM division. Can produce:

• Gelatin or veggie capsules
• Effervescent or compressed tablets
• Stickpacks or bottles of powders
• Gummies—our latest capability
