| Vegetable Composition | Clearly stated vegetable ingredients, with percentages listed in descending order by weight. | Supports accurate labeling, recipe consistency, allergen review, and customs classification. | Full ingredient specification, product formula, allergen declaration, and label artwork. | Essential |
| Moisture Content | Common commercial target: approximately 5%–10%, depending on the vegetable ingredients and drying process. | Lower, well-controlled moisture generally improves flowability and reduces the risk of caking and microbial growth. | Batch-specific certificate of analysis and an accredited moisture test method. | Essential |
| Particle Size | Typical powder specifications may range from about 40 to 100 mesh; the correct size depends on the final application. | Particle size affects dispersion, mouthfeel, dust formation, blending uniformity, and filling performance. | Mesh-size specification, sieve analysis, and retained-sample comparison. | High |
| Salt and Sodium Level | Choose a salt-free, reduced-sodium, or standard-sodium formula according to local nutrition requirements and consumer preferences. | Sodium content influences nutrition labeling, formulation costs, taste positioning, and suitability for clean-label products. | Nutrition specification, sodium assay, and finished-product nutrition calculation. | High |
| Flavor and Color Profile | Consistent vegetable aroma, natural-looking color, and no burnt, stale, rancid, or chemical off-notes. | Appearance and flavor consistency directly affect repeat purchases and batch-to-batch product quality. | Approved reference sample, sensory evaluation record, color specification, and stability data. | High |
| Microbiological Safety | Limits should comply with the destination market and the intended food application; Salmonella should be absent in the tested analytical portion where required by applicable standards. | Dehydrated foods are low-moisture products but can still carry pathogens if raw materials or handling controls are inadequate. | Recent microbiological COA covering Salmonella, total plate count, yeast and mold, and coliforms or E. coli where applicable. | Essential |
| Heavy Metals and Contaminants | Results must remain within the legal limits of the importing country for the relevant food category. | Vegetables and spices may be monitored for lead, cadmium, pesticide residues, mycotoxins, and other contaminants. | Accredited laboratory reports, pesticide-residue screening, heavy-metal testing, and contaminant compliance statement. | Essential |
| Food Safety System | Prefer a documented HACCP-based system and a current, independently audited food-safety certification where required by the buyer. | Preventive controls reduce contamination risk and make supplier approval and import audits more efficient. | Valid food-safety certificate, audit summary, HACCP plan, traceability procedure, and recall procedure. | Essential |
| Packaging and Barrier Protection | Food-grade, moisture-barrier packaging with a secure inner liner; packaging size should match warehouse and production needs. | Proper packaging protects powder quality during transport, storage, and repeated handling after opening. | Packaging specification, food-contact declaration, pallet details, and transport-condition recommendations. | High |
| Shelf Life and Storage | Many dry vegetable powders have a stated shelf life of about 12–24 months when kept sealed in a cool, dry, dark environment; confirm by product-specific testing. | Shelf life affects inventory planning, landed-cost risk, claims management, and suitability for long-distance shipping. | Stability study, expiry-date policy, storage instructions, and minimum remaining shelf-life at shipment. | High |
| Traceability | Each lot should be linked to raw-material records, processing dates, test results, packaging records, and shipment documents. | Lot traceability enables rapid investigation, targeted withdrawal, and compliance with food-import requirements. | Lot-code format, traceability exercise, production record, and recall-test evidence. | Essential |
| Application Performance | Test in the intended product, such as instant soup, snack coating, sauce, seasoning blend, bakery filling, or ready meal. | A powder that performs well in one application may not disperse, dissolve, or retain flavor equally well in another. | Application sample, recommended dosage, dispersion test, pilot-batch results, and sensory evaluation. | High |
| Regulatory and Label Compliance | Ingredient names, additives, allergens, nutrition information, origin statements, and claims must match destination-market rules. | Non-compliant labeling can cause customs delays, relabeling costs, product rejection, or a market withdrawal. | Regulatory review, ingredient and additive status, allergen statement, certificate of origin, and import documentation. | Essential |
| Commercial Supply Capability | Evaluate minimum order quantity, lead time, production capacity, sample-to-bulk consistency, and agreed quality tolerance. | Reliable supply is necessary to maintain production schedules and avoid emergency purchases at higher landed costs. | Quotation, lead-time schedule, capacity statement, quality agreement, and sample approval record. | High |
