Mayonnaise is a semi-solid, oil-in-water emulsion that requires precise process control. Small mistakes in shear, temperature, or ingredient addition can break the emulsion, causing oil separation and inconsistent viscosity. This is why commercial mayonnaise production is far more controlled than making mayonnaise at home.
Industrial production lines use high-shear homogenizers, vacuum deaeration, inline viscosity monitoring, and CIP-compatible filling systems to deliver consistent quality, food safety, and shelf stability at high production volumes. Understanding these processes helps manufacturers choose the right mayonnaise production line and reduce downtime.
This guide explains the ingredients, the commercial mayonnaise manufacturing process, and the equipment used to produce and package mayonnaise efficiently, including automatic sauce filling machines.
What Is Mayonnaise Made Of?
Mayonnaise definitions and composition requirements can vary by market and product standard. Codex texts are not automatically law in every jurisdiction, so confirm the applicable specification before using a composition threshold. In practice, the formula balances oil, emulsifiers, acids, stabilizers and the required food-safety controls to achieve the intended texture and stability.
While ingredient ratios vary between manufacturers and product types, every commercial formula is designed to produce a stable, smooth emulsion that meets quality and food safety standards. Each ingredient has a specific role, from building viscosity and enhancing flavor to improving shelf life and preventing oil separation. Understanding these functions helps manufacturers optimize both product quality and production efficiency.
The table below outlines the primary ingredients used in commercial mayonnaise production, their typical proportions, and their role in the manufacturing process.
| Ingredient | Typical % in Commercial Formula | Function in Mayonnaise Production Process | Critical Control Point |
| Vegetable Oil | 70%–80% | Continuous phase; provides body, mouthfeel, viscosity | Oil temperature 20–25°C; filtered to 50–100 μm |
| Liquid Egg Yolk | 4%–8% | Natural emulsifier via lecithin; stabilizes oil-water interface | Pasteurized; pH <4.5; stored at 0–4°C |
| Vinegar (5% Acidity) | 2%–4% | Lowers pH to 3.6–4.1 for microbial safety; adds flavor | Final pH verification before filling |
| Water | 5%–10% | Disperses salt and sugar; forms water phase of emulsion | RO/UV treated; low hardness |
| Salt | 1%–2% | Flavor enhancement; reduces water activity | Fully dissolved in water phase |
| Sugar | 1%–4% | Balances acidity; contributes to browning if baked | Pre-hydrated to avoid lumps |
| Stabilizers | 0.1%–1% | Xanthan gum or modified starch for reduced-oil or freeze-thaw stability | Hydration time 15–30 minutes |
| EDTA | 50–75 ppm | Chelates metals; prevents oxidation and rancidity | Regulatory limit check |
The following subsections outline how each input affects the industrial mayonnaise manufacturing process.
1. Vegetable Oil
Oil proportion varies by formulation, target texture, market and process. Soybean, rapeseed, sunflower, canola and other oils may be used where their sensory, oxidative-stability and processing characteristics fit the product. Confirm the approved formula rather than applying a universal percentage.
Some also choose light olive oil, while extra virgin olive oil or regular olive oil can produce a stronger flavor and may become slightly bitter after blending.
2. Egg Yolk
Egg yolk contributes emulsification, but the egg ingredient and process must meet the applicable food-safety requirements. For U.S. food-service contexts, FDA guidance points to pasteurized eggs or egg products for mayonnaise and similar foods that are not thoroughly cooked; manufacturers should confirm the rule and process for the target market.
Typical usage is 4–8% of the formula. The phospholipids adsorb at the oil-water interface, preventing coalescence. Over-processing denatures yolk proteins, so shear and temperature are controlled during the high-shear stage.
A homemade mayo recipe typically starts with one large whole egg or raw egg, although pasteurized eggs are recommended for better food safety. Some specialty recipes separate the egg whites or combine egg and lemon juice before emulsification.
3. Vinegar or Lemon Juice
Acid can influence pH, flavor and microbial control, but the target pH and process limits are product-specific. For U.S. shelf-stable acidified foods in hermetically sealed containers, FDA requirements can include product-specific process controls and filings; confirm the applicable classification, process authority and jurisdiction before setting a critical limit. Distilled vinegar, lemon juice and other acids must be evaluated in the approved formulation.
Besides distilled vinegar, recipes may also use white wine vinegar, apple cider vinegar, or other wine vinegar varieties. Some cooks substitute bottled lemon juice or add extra lemon juice to brighten the flavor.
4. Salt, Sugar and Other Additives
Salt, sugar, stabilizers and permitted antioxidants are formula-dependent controls. Their levels should be set in the approved recipe and verified against the target market, water activity, sensory profile and process. Pre-hydration and dispersion can help prevent lumps that interfere with pumps or nozzles, but the required procedure should be confirmed during product trials.
How Is Mayonnaise Made Commercially?
The commercial mayonnaise production sequence focuses on creating a stable emulsion and protecting it through filling. Here’s how is mayonnaise made at scale.
Step 1 — Raw Material Preparation
Ingredients are staged in temperature-controlled rooms. Oil is filtered to 50–100 microns to remove particulates that could damage pumps.
Water-phase ingredients are dissolved in a pre-mix tank with agitation selected for the formula. Temperature, load-cell or flow-metering controls, Brix, pH and yolk-solids checks should be set from the approved recipe and quality plan rather than copied from a generic machine specification.
Step 2 — Mixing and Emulsification
The emulsification stage combines controlled oil addition, shear and—where appropriate—vacuum deaeration. Vacuum level, rotor-stator speed, addition rate and shear time must be established through formulation trials because they affect air incorporation, droplet structure, texture and downstream filling behavior.
Industrial mayonnaise lines may use vacuum emulsifying mixers to manage texture, air incorporation and process consistency. Temperature, mixing time, contact materials, cleaning method and any CIP features should be selected for the formula and validated process. KING PACK’s vacuum emulsifying mixer options can be reviewed as one equipment route; final materials and sanitation functions require project-specific confirmation.
Step 3 — Homogenization and Quality Control
Some lines use a secondary colloid mill or homogenizer when the formulation and target texture require it. Pressure, shear, residence time and viscosity targets should be established with representative product and checked with the agreed measurement method. QC may include pH, microbiological tests, sensory checks and stability tests, depending on the product and market.
Step 4 — Storage and Transfer
Finished mayonnaise may be held in a temperature-managed hopper or storage tank with gentle agitation selected to limit separation and air re-entry. Pump type, line geometry, transfer conditions, cleanability and any pigging or CIP approach should be confirmed against the formulation, changeover plan and site procedure.
Step 5 — Filling and Packaging
After production, mayonnaise must be filled hygienically into the selected bottle, jar, tube or pouch. Product viscosity and sensitivity to shear, air and temperature influence the choice of piston, servo-pump, auger or other dosing system. Nozzle shut-off and product trials can help manage dripping and stringing, but acceptance limits should be agreed for the actual pack.
Automatic filling machines can support repeatable dosing, hygiene and line integration when the filler, nozzle, product path and control method match the formula and package. Do not publish a universal accuracy figure; define the measurement method, sample size and acceptance limits in the FAT or qualification plan.
For example, King-Pack’s piston fillers use ceramic plungers that resist wear from acid and salt, maintaining accuracy over long runs. Nozzles dive and follow the product level to reduce air pickup and stringing. After filling, inline cappers, induction sealers, and X-ray checkweighers complete the pack.

Industrial Mayonnaise Manufacturing Process Flow
A typical mayonnaise production line follows this sequence:
Each step has PLC-controlled parameters logged for traceability. Deviations trigger alarms and lock out the batch until QA review.
What Equipment Is Used for Mayonnaise Production?
Commercial lines integrate several machines, and sizing should start from required saleable output, available production time, changeovers, cleaning, expected downtime and downstream constraints. Do not select a nominal capacity without confirming the product, package and acceptance conditions.
The table below maps each major unit in a mayonnaise production line to viscosity range, critical specs, and common applications. Use it to match equipment to your target output and container type before sizing pumps, nozzles, or CIP circuits.
| Equipment Type | Best For | Viscosity Range | Key Specs for Mayonnaise | King-Pack Example |
| Vacuum Emulsifying Mixer | Primary emulsification, batch process | Product-specific viscosity; confirm by test | Shear, vacuum, contact materials and CIP scope are configuration-dependent | KPGZA Series Vacuum Emulsifier |
| Colloid Mill | Secondary size reduction after pre-mix | Product-specific viscosity; confirm by test | Pressure, gap, speed and sanitary design require product trials | Optional inline homogenizer |
| Piston Filling Machine | Jars, bottles, wide-mouth containers | Product-specific viscosity; confirm by test | Servo/piston options; acceptance limits and contact materials require project confirmation | KPF Automatic Piston Filler |
| Servo Pump Filler | Bottles, squeeze tubes, pouches | Product-specific viscosity; confirm by test | Rotary lobe or gear pump, no-drip cut-off | King-Pack Sauce Filling Line |
| Premade Pouch Filling Machine | Stand-up pouches, spouted packs | Product-specific viscosity; confirm by test | Nitrogen-flush and zipper options; compliance scope requires project-specific verification | KPGZ-200P Pouch Filler |
Each unit affects the next stage. A stable emulsion from the mixer prevents filling errors, while proper filler design protects the emulsion you just created. The next sections detail how each machine works.
Vacuum Emulsifying Mixer
This is the core unit for the industrial mayonnaise manufacturing process.
High-shear mixing, emulsification, temperature management, vacuum options and cleanability may be relevant to high-viscosity products. Vessel volume, vacuum level, homogenizer configuration and CIP/SIP scope should be selected from the formula, batch size and validation requirements rather than a universal range.

Mayonnaise Filling Machine
Applications include mayonnaise, sauces, dressings and other cream products. Useful specifications to review include the dosing principle, product-contact materials, sanitary connections, cleanability, changeover, controls and no-container/no-fill logic; final requirements depend on the formula and line design.
For higher-output projects, rotary piston fillers may be considered where the product, package and line balance support them. Final speed and dosing performance must be demonstrated with representative product and packaging. Dive-fill nozzles, anti-drip cut-off and heated hoppers are configuration options only when trials show they are appropriate.
Automatic Sauce Packaging Machine
Suitable for ketchup, mayonnaise, salad dressing, and other viscous sauces. These lines integrate filling, capping, labeling, and case packing. For pouches, premade pouch filling machines use servo augers or pumps, nitrogen flushing, and zipper sealing.
Pouch formats can support stand-up, three-side-seal and spouted packs. Packaging format, gas flushing, sealing and hygiene requirements should be confirmed against the product, film and applicable site procedure.
Benefits of Using an Automatic Mayonnaise Production Line
- Higher Production Efficiency: Continuous or semi-continuous lines cut batch times. A 1,000 L vacuum mixer can output a batch in 20–30 minutes vs. 60+ minutes with low-shear methods.
- Consistent Product Quality: Closed-loop control of shear, vacuum, and temperature removes operator variability. Droplet size stays within a 2–8 micron target.
- Filling giveaway should be evaluated with the agreed measurement method and production baseline. Any claimed material saving must be calculated from the customer’s actual fill target, measured variation, annual volume and product cost—not from a generic accuracy assumption.
- Reduced Labor Requirements: A full line from mixer to palletizer can run with 2–4 operators, compared to 8–10 for manual lines.
- Enclosed product paths, cleanable contact surfaces and a documented cleaning process can support hygienic production. Select materials, seals and cleaning controls against the formulation, allergen profile, site procedure and applicable food-safety requirements; do not treat a material grade alone as proof of compliance.
- Easier Production Management: SCADA collects OEE, batch records, and traceability data for audits.
Homemade Mayonnaise Recipe vs Industrial Production
Commercial mayonnaise and homemade mayonnaise share the same principle: combining oil and water into a stable emulsion. Difference is equipment, production scale, and level of process control. A homemade mayonnaise recipe makes small batches, while industrial uses vacuum emulsifying mixers and high-shear homogenizers for consistent texture and quality at industrial scale.
Easy homemade mayonnaise recipe: one whole egg, 1 tablespoon of Dijon mustard, vinegar, 1 cup of oil. All traditional recipes use the same emulsification process for smooth, creamy mayonnaise.
For a stable emulsion, many use immersion blender, stick blender, or hand blender.
- A stick or immersion blender works best when blender head is fully submerged in a tall container or mason jar to emulsify evenly from bottom of the jar upward.
- A food processor suits larger batches, but a small bowl attachment is better for smaller quantities.
- A stand mixer works but takes longer for same consistency. Keep food processor running while gradually adding the oil.
As mixture begins to emulsify, mayonnaise starts forming at bottom of the container. Pour oil in a slow, steady stream – whether you pour the oil, slowly pour or slowly add, you must add oil gradually so emulsion remains stable. Rushing making mayo overwhelms the emulsifier and it will separate.
Some add herbs, spices, or other natural flavors for taste buds, others buy mayonnaise. Commercial manufacturers get smooth texture via automated metering systems that precisely control oil addition, mixing speed, temperature, and vacuum conditions, controlling droplet size, shelf stability, and quality standards without manual pouring.
Broken Mayonnaise: How to Fix Broken Mayonnaise
A broken mayonnaise occurs when the oil and water phases separate before a stable emulsion forms. At home, this usually happens when too much oil is added too quickly or when the ingredients are at very different temperatures, leaving a thin, runny mess instead of a smooth spread.
Fortunately, it’s often possible to fix broken mayonnaise. A common method is to place a fresh egg yolk in a clean bowl and slowly whisk the separated mixture into it a little at a time. The new yolk provides fresh emulsifying agents that help rebuild the emulsion and recover the broken mayo.
Industrial manufacturers reduce this risk by carefully controlling oil addition rates, mixing speed, temperature, and vacuum conditions throughout the emulsification process. Automated process controls make emulsion failure far less likely, which helps minimize product waste and maintain consistent quality from batch to batch.
How to Choose a Mayonnaise Production Equipment Manufacturer?
Selecting a mayonnaise production line manufacturer impacts uptime for the next 10–15 years. Evaluate these factors:
- Manufacturing experience: Look for 10+ years in sauces and emulsions. Ask for references in your region.
- Machine quality: confirm contact-material compatibility, gasket specification, washdown design, controls, cleanability and documentation against the user requirement specification. Do not assume FDA, EHEDG or other compliance from a generic component description; verify the applicable certificate or declaration for the project.
- Production capacity: Match mixer and filler speeds. A 500 L mixer should feed a filler at 80–120 bpm for balance.
- Customization capability: Can they adjust nozzle diameter for your jar? Add nitrogen blanketing?
- After-sales support: 7×24 technical support and local spare parts matter. King-Pack, for example, provides on-site installation and operator training.
- Compliance requirements: CE, UL, GMP, and 3-A standards depending on market.
