Vitamin B1 Mononitrate (Thiamine Mononitrate) · Food-Grade Vitamin B1 for Enrichment & Fortification

Key characteristics

• Chemical name: Thiamine mononitrate (vitamin B1 mononitrate).
• Form: Typically a white to off-white, odourless or almost odourless, crystalline powder.
• Stability: More stable than thiamine hydrochloride in many dry blends and premixes, especially at neutral pH and low water activity.
• Solubility: Sparingly soluble in water compared with thiamine hydrochloride, which is an advantage for dry blending and shelf life but requires appropriate formulation design for instant beverages.
• Function: Used to restore or increase vitamin B1 content in refined flour and cereal products, and to formulate B-complex and multivitamin systems in foods, beverages and supplements.

Atlas helps formulators select thiamine mononitrate vs. thiamine hydrochloride depending on the desired application, solubility, stability and labelling strategy.

Indicative specification points

Final specifications are agreed with your QA/QC teams. Typical food-grade thiamine mononitrate parameters include:

• Assay: usually in the range 98.0–101.0% on dried basis.
• Identification tests: confirm thiamine structure and nitrate content according to pharmacopeial / food-grade methods.
• Loss on drying: controlled to maintain stability and flowability.
• Residue on ignition / sulphated ash: limited in line with specification.
• pH (in solution): monitored for consistency and quality control.
• Heavy metals and impurities: controlled to meet food or nutrition ingredient requirements.
• Particle size and bulk density: tailored for premix design, uniform blending and low dusting.
• Microbiological criteria: suitable for flour, bakery, cereal and nutrition applications.

Each batch is supplied with a Certificate of Analysis (COA) and a detailed technical data sheet. Additional documentation (GMO status, allergens, dietary suitability, contaminants, origin) can be provided as part of your supplier approval process.

Flour, bakery & cereal products

• Wheat flour enrichment – thiamine mononitrate is widely used to restore B1 levels in refined flour after milling, often together with other vitamins and minerals (e.g. riboflavin, niacin, iron).
• Bread, rolls and bakery products – vitamin B1 from premixes is carried through into finished bakery products, supporting nutrition labelling and enrichment standards.
• Breakfast cereals and cereal bars – used together with other B-vitamins and minerals in coatings, syrups or base blends to create fortified cereal portfolios.
• Fine bakery and pastry items – selected recipes may use vitamin premixes containing thiamine to support fortified ranges and on-pack claims.

Instant noodles & snack foods

• Instant noodles – thiamine mononitrate can be blended into noodle flour or seasoning premixes to support vitamin B1 claims, subject to local regulations.
• Extruded snacks and crackers – added via base dough or seasoning premixes to create better-for-you snack concepts.

Beverages & powdered drinks

• Powdered beverages (e.g. malt drinks, chocolate beverages and nutrition drinks) where B1 is added in dry premix form, together with sweeteners, acidulants and flavours from the Flavorings portfolio.
• Ready-to-drink fortified beverages – thiamine mononitrate can be part of a vitamin premix added prior to or after heat treatment, with attention to stability, pH and processing conditions.

Nutrition, supplements & premixes

• B-complex and multivitamin premixes used for foods, beverages and dietary supplements, where thiamine mononitrate is one component alongside other B-vitamins.
• Infant, follow-on and young child nutrition – vitamin B1 is an essential nutrient in many regulatory frameworks. Dedicated grades and documentation are required for these applications and must follow market-specific regulations.
• Clinical and medical nutrition – thiamine mononitrate may be part of tailored vitamin premixes for specialised nutrition products, with strict quality and regulatory requirements.
• Dietary supplements – used in tablets, capsules and powders as a source of vitamin B1, often in combination with other B-vitamins and minerals.

Formulation guidance

• Thiamine mononitrate is typically incorporated via vitamin premixes to ensure homogeneous distribution at very low inclusion levels.
• Dosage is determined by:
  • Target vitamin B1 content per serving,
  • Local enrichment and fortification regulations,
  • Process and storage losses, and desired on-pack claims.
• In heat-treated products, formulation must account for thermal stability and potential losses during baking, extrusion, sterilisation or drying.
• Thiamine’s characteristic odour at high levels makes precise premix design and dosage control important to avoid sensory issues.
• Regulatory teams should confirm maximum levels, enrichment standards and claim conditions in each country and product category.

Quality & documentation

• Supplied as food or nutrition-grade vitamin B1 mononitrate with agreed specifications for assay, impurities, physical properties and microbiological limits.
• Each lot is accompanied by a Certificate of Analysis (COA) and a technical data sheet describing key parameters and analytical methods.
• Additional documentation can include GMO and allergen statements, contaminants and heavy metal data, dietary suitability (e.g. vegetarian/vegan where applicable), BSE/TSE statements and origin declarations.
• Production facilities typically operate under recognised ISO and food safety management systems; Halal and/or Kosher certificates may be available depending on producer and grade.
• Customers remain responsible for regulatory compliance, enrichment standards, fortification limits, nutrition and health claims and label declarations in each destination market.

Packaging, storage & logistics

• Standard packaging: usually 25 kg fibre drums or cartons with multi-layer inner bags for moisture protection; alternative sizes can be discussed for specific projects.
• Suitable for full-container loads or mixed-container shipments together with other vitamins, minerals, sweeteners, thickeners and functional ingredients.
• Store in a cool, dry place, protected from direct light, heat, moisture and strong odours to maintain vitamin potency and powder flowability.
• Under correct storage conditions, typical shelf life is indicated on the product specification and COA; customers should validate vitamin retention in their own applications.
• Atlas coordinates export, customs and quality documentation from Ankara, Türkiye, under agreed Incoterms such as FOB, CFR or CIF, depending on customer preference.
