Bulk Cold-Pressed Edible Walnut Oil

Atlas Nut Supply, LLC supplies bulk cold-pressed edible walnut oil for manufacturers, brands, and distributors who need a consistent procurement lane (not a one-off spot buy). We cooperate with California supplier programs to match your sensory profile, oxidation stability targets, packaging, documentation, and delivery requirements for U.S. distribution and export shipments.

Cold-pressed walnut oil is typically chosen when walnut aroma and taste matter in the finished product. In bulk manufacturing programs, it’s commonly qualified by odor/flavor, acid value/peroxide targets, color/clarity, and pack-out constraints.

Bulk supply focus: what buyers qualify

Cold-pressed edible walnut oil programs are typically evaluated on sensory consistency and oxidation stability first—then packaging and documentation. We build quote-ready programs around what procurement and QA teams actually check:

  • Sensory profile: target odor/flavor notes (mild vs pronounced), acceptable variation by lot, suitability for your application
  • Oxidation limits: defined thresholds (commonly acid value and peroxide value) to support shelf-life
  • Color & clarity: filtration expectations (as required) and appearance targets
  • Packaging & handling: drums or totes with receiving constraints and pallet parameters supported
  • Documentation: COA, traceability, allergen statements, country of origin, and supporting compliance docs upon request
  • Delivery lanes: U.S. domestic routes and export shipments depending on destination requirements

If you have a benchmark oil or finished-product reference, mention it—this helps align sensory expectations and reduce lot-to-lot surprises.

Cold-pressed vs refined walnut oil

Manufacturers choose cold-pressed programs when walnut character is part of the product identity. Refined walnut oil may be preferred when you need a more neutral oil with tighter sensory/color limits.

  • Choose cold-pressed for flavor-forward dressings, sauces, finishing oils, and premium blends
  • Choose refined when you need a more neutral profile for higher formulation flexibility
  • Choose crude when the oil is a processing input for downstream refining/blending

If you’re unsure, tell us the end application and heat exposure (if any). We’ll help match the right program.

Cold-pressed edible walnut oil options

Common program formats (availability varies by supplier program and season):

  • Cold-pressed edible walnut oil (bulk): sensory + oxidation targets defined for manufacturing
  • Crude/refined alternatives: available in some programs for different sensory or processing needs
  • Pack-out: drums or totes depending on receiving constraints
  • Documentation: COA and supporting compliance documents upon request (program-dependent)
Odor/Flavor Target Acid Value / PV Limits Color / Clarity Drums or Totes COA + Traceability

Bulk packaging is typically drums or totes. Share your receiving constraints (dock access, height limits, temperature control preferences) and we’ll align the right pack-out.

Industrial applications

Typical manufacturing, culinary, and ingredient uses:

  • Dressings & sauces: flavor-forward emulsions and specialty formulations
  • Finishing applications: culinary lines where walnut aroma is desired
  • Bakery & confectionery blends: fat systems where nut character supports the profile
  • Nutritional systems: ingredient blends where documented inputs and consistent lots matter

Product specifications (typical quote parameters)

Specs vary by supplier program, crop year, and filtration/handling. The table below shows common parameters used to qualify edible walnut oil. If you have an internal spec sheet, send it and we’ll match a program to your targets.

Parameter Typical target / range (program-defined)
Acid value (mg KOH/g) Define maximum acceptable level for your program (often used as an FFA proxy)
Peroxide value (mEq/kg) Define maximum acceptable level to support oxidation stability and shelf-life targets
Moisture & volatiles (%) Low moisture targets support handling and stability (program dependent)
Insoluble impurities (%) Define filtration/clarity expectations for your receiving and processing needs
Iodine value (g I2/100g) Useful for confirming oil identity/unsaturation (program dependent)
Saponification value (mg KOH/g) Common identity/quality parameter (program dependent)
Color / clarity Define appearance range and filtration requirements (clear vs lightly hazy)
Sensory (odor/flavor) Target “mild” vs “pronounced” walnut notes + acceptable variation by lot
Metals (Fe/Cu) & contaminants Specify limits if required by your QA program or destination market
No additives (cold-pressed) Many cold-pressed programs are specified as “no additives” (program dependent)

Tip: If you need “cold-pressed” specifically, include your expectations for filtration, sensory profile, and oxidation limits in the same request—this reduces rework and speeds up approval.

Composition & fatty-acid profile (useful for R&D)

Walnut oil is naturally rich in polyunsaturated fatty acids, which is one reason buyers focus on oxidation targets and storage discipline. If you’re building a nutritional panel or running R&D, share your label goals and we’ll help align a program.

Major fatty acids Typical % range (reference values; lot/program dependent)
Linoleic (C18:2) Commonly the largest fraction in walnut oil
Oleic (C18:1) Varies inversely with linoleic in many lots
Linolenic (C18:3) Secondary PUFA fraction (program/varietal dependent)
Palmitic (C16:0) + Stearic (C18:0) Smaller saturated fractions (still relevant for identity/consistency checks)

If you’re comparing suppliers, ask for COA history (multiple lots) where possible—this helps model sensory and oxidation variability over time.

Storage & shelf-life management

Storage guidance depends on your exact program, packaging, and facility conditions. In general, the goal is to reduce exposure to heat, light, and oxygen and to maintain lot-level traceability.

  • Protect from heat/light: improves stability over your target window
  • Minimize oxygen exposure: keep containers sealed; avoid repeated headspace cycling
  • FIFO rotation: align receiving and production schedules to reduce long dwell time
  • Traceability: record lot IDs through production and finished goods
  • Confirm receiving conditions: temperature controls if required for your facility

Tell us your intended use (dressings/sauces, finishing oil, blends, or other) and your desired shelf-life window, and we’ll recommend program-appropriate best practices.

Packaging: drums & totes

Bulk edible walnut oil is typically packed for industrial receiving. Include constraints in your inquiry to avoid receiving issues.

  • Pack types: drums or totes (program-dependent)
  • Pallet configuration: max height, weight limits, and dock constraints
  • Receiving constraints: forklift access, internal handling preferences, temperature controls if needed
  • Labeling: lot ID, production date (where applicable), documentation alignment for traceability

Documentation & compliance support

Typical documentation available upon request (varies by supplier program):

  • COA (including key quality parameters such as acid value and peroxide, as applicable)
  • Traceability / lot documentation
  • Allergen statements and handling declarations
  • Country of origin documents
  • Export documentation support depending on destination requirements

If you need certifications or special compliance documents, list them in your inquiry so we can match the right supplier program.
