What key features should be considered when selecting a mayonnaise emulsifier?
Selecting the right mayonnaise emulsifier depends on production volume, product specifications, and compliance requirements. Key features to evaluate include:
a. Shear Force Capacity
Mayonnaise requires high, consistent shear to achieve stable emulsification. Look for equipment that specifies shear rates (typically 8,000–12,000 s⁻¹) and can handle the high oil content (65–80% of mayonnaise formulations). Insufficient shear will result in a thin, runny product or phase separation; excessive shear may over-process ingredients and affect texture.
b. Temperature Control
Egg yolks and oil are sensitive to heat—even small temperature spikes (above 25°C/77°F) can cause egg proteins to coagulate, breaking the emulsion. Opt for emulsifiers with jacketed mixing chambers or integrated cooling systems to maintain temperatures between 15–20°C (59–68°F) during processing.
c. Ingredient Feeding and Mixing Sequence Control
Mayonnaise production requires a specific ingredient addition order (e.g., adding oil slowly to the egg yolk-vinegar base). Look for equipment with programmable feeding systems (e.g., metered oil pumps) to ensure precise, gradual addition—this prevents "breaking" the emulsion by avoiding sudden oil overloads.
d. Sanitary Design
Food safety is non-negotiable. Choose emulsifiers with:
CIP (Clean-in-Place) compatibility (to streamline cleaning and reduce downtime between batches).
e. Scalability
For small-batch production (e.g., artisanal mayonnaise), a tabletop or semi-automatic emulsifier may suffice. For industrial-scale operations (1,000+ liters per batch), select a continuous-flow emulsifier that integrates with production lines to avoid batch-to-batch delays.
