Dehydrated garlic onion

When sourcing dehydrated garlic and onion, you must prioritize moisture content, which should typically be below 6% to prevent microbial growth and clumping. Color consistency is vital; garlic should be creamy white to pale yellow, while onions vary by type (white, yellow, or red) but should show no signs of browning or scorching. Additionally, evaluate the rehydration ratio, as high-quality products should effectively regain their texture and aroma when exposed to moisture.

To ensure food safety and market entry, suppliers must possess HACCP (Hazard Analysis and Critical Control Points) and ISO 22000 certifications. For specific markets like the US, FDA registration and compliance with the FSMA (Food Safety Modernization Act) are required. If you are targeting niche markets, verify Kosher, Halal, or Organic (USDA/EU) certifications to meet consumer dietary requirements.

AD (Air Dried) is the most common and cost-effective method, suitable for powders and granules used in industrial food processing. FD (Freeze Dried), while more expensive, preserves the original cellular structure, flavor, and nutritional profile much better, making it ideal for high-end instant soups or retail spice mixes. You should choose based on your target price point and application scenario.

Clearly define the mesh size for powders (usually 80-100 mesh), the dimensions for granules (e.g., 0.5-1mm or 1-3mm), and the thickness for flakes (typically 1.5mm-2mm). Ensure the supplier uses optical sorting technology and strong magnets/metal detectors to eliminate foreign materials like stones, glass, or metallic particles.

Request a COA (Certificate of Analysis) for every batch. It is highly recommended to use third-party inspection services (like SGS or Intertek) to conduct random sampling at the supplier's warehouse before shipment to test for pesticide residues, lead, and arsenic levels to ensure they meet your country's import limits.

Focus on volume-based pricing tiers; for dehydrated vegetables, prices fluctuate based on the annual harvest cycle. Negotiate for fixed-price contracts if you have long-term needs to avoid seasonal price spikes. Always ask for Gold Member status or Audited Supplier reports on Made-in-China.com to verify the factory's actual production capacity.

Dehydrated products are highly hygroscopic (moisture-absorbing). Ensure the use of double-layered packaging (PE inner bag + aluminum foil or heavy-duty carton). For sea freight, request silica gel desiccant packets inside the container and ensure the container is hermetically sealed to prevent 'container rain' from damaging the cargo.

Utilize Secured Trading Services offered by platforms like Made-in-China.com to protect your payment. Use Letter of Credit (L/C) for large bulk orders or Telegraphic Transfer (T/T) with a deposit (e.g., 30% down, 70% against B/L copy) only after verifying the supplier's business license and export history.
