Organic Whole Raw Rye Grain Seeds for Sprouting and Juicing Ryegrass

Here are standard specifications for rye grain, commonly used for milling (bread, flour), distilling, and animal feed:

Rye Grain Specifications

1. General Description

• Product: Rye (Secale cereale
• Type:
  • Milling rye (food-grade)
  • Feed rye
• Color: Greenish-grey to light brown
• Odor: Clean, fresh (free from musty, sour, or chemical smells)
• Condition: Clean, sound, and fit for intended use

2. Physical Quality Parameters

ParameterSpecification

Moisture Content

Max 12.5% – 14.5%

Foreign Matter

Max 1.0% – 2.0%

Broken/Shrunken Kernels

Max 3.0% – 5.0%

Damaged Kernels

Max 2.0% – 5.0%

Heat-Damaged Kernels

Max 0.5%

Test Weight

Min 70–75 kg/hl

Other Grains

Max 2.0%

3. Milling Quality Parameters (Food-Grade Rye)

ParameterSpecification

Protein Content

8% – 11%

Falling Number

Min 150–200 seconds

Ergot Content

Max 0.05% (very strict due to toxicity)

Kernel Uniformity

Good and consistent size

Color

Uniform and typical of variety

4. Feed Rye Requirements

• Less strict than milling rye
• Higher tolerance for:
  • Broken and damaged grains
  • Lower test weight
• Must still be safe and free from harmful contaminants

5. Purity & Cleanliness

• Free from:
  • Live insects
  • Rodent contamination
  • Moldy or rotten grains
• Minimal presence of:
  • Weed seeds
  • Other cereals
• Very low tolerance for ergot (toxic fungus)

6. Chemical / Safety Limits

ParameterLimit

Aflatoxin

Max 10 ppb

Mycotoxins (e.g., DON)

Within regulatory limits

Ergot Alkaloids

Within safe limits

Pesticide Residues

Within permissible limits

Heavy Metals

Within safe limits

• Distilling (whisky, spirits)
• Animal feed
• Food processing

11. Standards & Compliance

• Must comply with:
  • National grain grading standards
  • Phytosanitary requirements
  • Food safety regulations (e.g., Codex Alimentarius)
