Mayonnaise

When sourcing mayonnaise, the oil content is the primary indicator of quality; standard mayonnaise typically contains 70-80% vegetable oil (soybean, sunflower, or canola). You must verify the emulsification stability to ensure the product does not separate during transit. Additionally, check the pH levels (usually between 3.3 and 4.5) to ensure microbial safety and the viscosity (measured in centipoise) to match your specific application, whether it is for dipping, spreading, or industrial food processing.

As a processed food product containing eggs, mayonnaise is subject to strict regulations. Ensure the supplier is HACCP and ISO 22000 certified for food safety management. For specific markets, you may require FDA registration (USA), EFSA compliance (EU), or Halal/Kosher certifications depending on your target consumer base. Always request a Certificate of Analysis (COA) for every batch to verify the absence of pathogens like Salmonella and Listeria.

Packaging choice directly affects the Total Cost of Ownership (TCO). For retail, PET bottles or glass jars are standard, but for food service, 5kg to 20kg buckets or flexible BIB (Bag-in-Box) systems are more cost-effective. Ensure the packaging includes an oxygen barrier to prevent lipid oxidation, which causes rancidity. Sourcing high-barrier multi-layer plastics can extend shelf life to 9–12 months without heavy refrigeration, reducing logistics costs.

Yes, professional suppliers on Made-in-China.com often offer OEM/ODM services. You can request adjustments in sugar content, acidity, or spice profiles (e.g., adding garlic or chili). For health-conscious markets, prioritize suppliers capable of producing low-fat, vegan (egg-free), or cholesterol-free versions using modified starches or plant proteins as stabilizers.

The biggest risk is temperature fluctuation. While many commercial mayonaises are shelf-stable, extreme heat can cause emulsion breakdown (oil separation), and freezing can destroy the texture. It is highly recommended to use reefer containers (refrigerated containers) set between 5°C and 20°C for long-haul sea freight to maintain product integrity.

Utilize the Secured Trading Service on Made-in-China.com to protect your payments. Before placing a large order, conduct a factory audit or hire a third-party inspector (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI). This ensures the goods meet the agreed-upon sensory and safety specifications before the final balance is paid.

Focus on volume-based pricing tiers; mayonnaise production is highly automated, so increasing an order from 500 cartons to 1,000 can often yield a 10-15% price reduction. Also, negotiate the lead time, especially for custom formulations, which typically ranges from 15 to 30 days. Requesting free samples (buyer pays shipping) is a standard industry practice to validate taste and texture before commitment.

Many countries have strict biosecurity laws regarding egg derivatives. Ensure your supplier provides a Health Certificate issued by the exporting country's government authority. Check for any anti-dumping duties or specific import quotas on vegetable oils or processed foods in your specific country to avoid unexpected costs at the border.
