Annatto Extract E160b

Annatto Extract is a plant-derived yellow-orange food colour obtained from the seed coating of Bixa orellana. It is used by food manufacturers for warm yellow, golden, orange and cheese-orange shade development in dairy, cheese, butter, margarine, bakery, snacks, sauces, seasonings, confectionery and colour-standardisation programs. Industrial selection depends heavily on whether the target application needs an oil-soluble bixin grade, a water-soluble norbixin grade, an emulsion, a dispersion, a powder or a custom shade blend.

Technical purchasing notes

When reviewing Annatto Extract, compare the supplier specification against the intended application, target shade, colour strength, pH, fat content, protein content, heat process, light exposure, packaging format, label expectations and destination-market rules. Annatto is not one universal colour grade. Bixin-based products are normally used where oil solubility or fat-phase distribution is needed, while norbixin-based products are usually evaluated for water-based, protein-containing or aqueous systems.

For industrial purchasing, the most useful inquiry normally includes target shade, bixin or norbixin preference, colour strength, application matrix, pH, process temperature, required declaration, carrier restrictions, sample requirement, annual quantity, destination country and document requirements. If you are replacing beta-carotene, paprika, curcumin, synthetic yellow/orange colours or another annatto grade, provide the current dosage, shade target and approved reference sample.

Bixin vs norbixin: grade selection

Annatto Extract is mainly selected by pigment chemistry and solubility. Bixin is the principal oil-soluble carotenoid pigment in annatto seed coating and is commonly used for fat-rich systems such as cheese, butter, margarine and oil-based coatings. Norbixin is produced from bixin through alkaline processing and is more suitable for water-based or protein-containing systems where aqueous distribution is required.

Industrial application guidance

• Cheese and dairy: annatto is widely evaluated for cheddar-type cheese, processed cheese, cheese sauces and dairy spreads. Buyers should test colour distribution, whey loss, curd retention, pH, salt level and storage shade stability.
• Butter and margarine: oil-soluble grades can help standardize golden yellow shade across seasonal fat-colour variation.
• Snack seasonings: powder or dispersion grades may support orange cheese, barbecue, spicy, savoury and roasted seasoning shades.
• Bakery and fillings: annatto may be used in cakes, icings, fillings, creams and fat-based bakery systems where heat stability and shade retention are acceptable.
• Sauces and condiments: water-soluble or emulsified grades can support yellow-orange sauces, dressings, soups, spice blends and savoury bases.
• Confectionery: compatibility with acids, gel systems, cooking temperature, water activity and packaging must be checked.
• Meat and savoury systems: annatto can contribute warm yellow-orange tones to selected sausages, coatings, marinades, soups and prepared meals where permitted.
• Plant-based foods: useful for cheese alternatives, vegan spreads, sauces and meat analogues that require dairy-like or cooked-orange shades.

Colour strength and shade standardisation

Annatto products should be purchased by colour performance, not only by price per kilogram. Supplier specifications may express strength as bixin percentage, norbixin percentage, colour value, absorbance, optical density, E1% value, extract solids or application-standard strength. Buyers should confirm the measurement basis before comparing offers.

• Request colour strength method, wavelength, solvent, dilution, pH and calculation basis.
• Compare shade in the final product matrix, not only in water, oil or laboratory solvent.
• Use an approved colour standard, L*a*b* target, reference product or retained production sample.
• Confirm batch-to-batch colour tolerance and supplier standardisation process.
• Evaluate cost-in-use based on the dose required to match target shade.
• Check whether the offered grade is single-source, blended, emulsified, plated, beadletized or custom-standardised.

Stability and processing considerations

Annatto pigments are carotenoid-based and can be affected by oxidation, light, heat, pH, metals, emulsifier system, carrier oil quality and packaging oxygen barrier. Stability should be validated over the full process and shelf life. A colour that matches immediately after mixing may fade, brown, separate, stain packaging, migrate into fat, bind to protein or shift shade during storage.

• pH: check final product pH and pH drift during storage, especially for norbixin grades.
• Heat: validate pasteurization, cooking, baking, extrusion, spray drying or hot-fill conditions.
• Light: use light-exposure testing for transparent packaging, retail display and surface-coloured foods.
• Oxygen: control headspace oxygen and packaging oxygen transmission where oxidative fading is a risk.
• Metals: iron, copper and other trace metals may accelerate colour degradation.
• Proteins and salts: dairy, meat and sauce systems may require testing for binding, precipitation or shade change.
• Emulsifiers: emulsified annatto grades should be validated for droplet stability, ring formation and phase separation.
• Acids and preservatives: test interaction with citric acid, lactic acid, acetic acid, sorbates, benzoates and sulphites where relevant.

Specification checklist for buyers

A professional Annatto Extract specification should define pigment basis, source, colour strength, physical form, carrier system, contaminants and application guidance. Because annatto grades can differ significantly in colour strength and solubility, supplier qualification should combine technical documents with application trials.

• Botanical source and raw-material origin
• Colour basis: bixin, norbixin, mixed carotenoids, emulsion or standardised blend
• Colour strength, bixin content, norbixin content or colour value
• Analytical method for pigment content or absorbance
• Shade description and application-standard colour target
• Physical form: liquid, powder, oil solution, water solution, dispersion, emulsion, lake or beadlet
• Carrier, diluent, emulsifier, stabilizer, solvent or anticaking agent declaration
• Solubility, dispersibility, sedimentation, clarity or emulsion stability where relevant
• pH, heat, light and oxygen stability guidance
• Moisture, solids, viscosity, bulk density or particle size depending on grade
• Residual solvent information where solvent extraction is used
• Sulphite status and preservative declaration where relevant
• Microbiological limits including total plate count, yeast and mould, coliforms, E. coli and Salmonella
• Heavy metals, pesticide residues, mycotoxins or other contaminants where required
• Allergen, GMO, halal, kosher, vegan or vegetarian declarations where required
• Shelf life, storage conditions, packaging format and batch traceability

Quality control and factory handling

Annatto Extract should be controlled as a sensitive colour preparation. Liquid grades may settle or separate, powder grades may dust or clump, and emulsions may require controlled mixing before use. Manufacturing teams should validate the addition point, dispersion method, mixing time and dosing accuracy before scale-up.

• Approve each lot against COA, colour strength and retained reference sample before release to production.
• Check appearance, odour, separation, sediment, caking, container integrity and expiry date on receipt.
• Mix or homogenize liquid concentrates according to supplier guidance before dosing.
• Pre-disperse powders or beadlets where needed to prevent specking or uneven shade.
• Use food-compatible pumps, hoses, vessels and dosing equipment that can be cleaned effectively.
• Protect opened containers from light, oxygen, heat and contamination.
• Monitor finished-product colour visually and, where possible, by L*a*b* measurement.
• Retain production samples under normal and accelerated storage conditions for shade tracking.

Regulatory and labelling review

Annatto Extract is identified as E160b in many additive systems, but the exact regulatory treatment depends on source, extraction method, food category, dosage, carrier system and destination-market rules. Buyers should confirm whether the finished product should declare Annatto Extract, annatto colour, E160b, colour, colouring food, vegetable extract, spice extract or another locally accepted term.

Claims such as “natural colour”, “no artificial colours”, “colouring food”, “plant-based”, “vegan”, “clean label”, “non-GMO”, “halal” or “kosher” should be reviewed against the exact supplier grade, carrier system, processing method and market-specific legislation. Some markets distinguish between colour additives and colouring foods, so the same botanical source may not always have the same declaration.

Packaging, storage and logistics

Annatto Extract may be supplied in jerrycans, drums, bottles, bag-in-box packs, bags, cartons, pails or light-protective containers depending on the form. Packaging should protect against light, oxygen, heat, moisture and contamination. Buyers should confirm storage temperature, remaining shelf life, transport conditions and opened-container handling before purchasing.

• Request net weight, gross weight, pallet configuration and container loading quantity before confirming freight.
• Confirm whether the grade requires ambient, cool, refrigerated or frozen transport.
• Ask whether the product is packed in light-protective or oxygen-protective packaging.
• Confirm production date, expiry date, batch number and remaining shelf life before shipment.
• Check whether opened-pack storage differs from unopened-pack storage.
• Request packing photos, label draft and pre-shipment COA when import clearance or customer approval requires them.
• For export orders, confirm HS code guidance, document legalization needs and destination import requirements.
