One Food Additive Supplier, Multiple Sourcing Needs
Our multi-category food additive portfolio allows buyers to evaluate several ingredients through one supply relationship.
One Supplier:Source multiple food additive categories from one experienced supplier.
One Procurement Process:Simplify communication, quotation and order coordination.
One Quality Communication Channel:Make specification and documentation discussions easier for purchasing and QA teams.
Flexible Product Selection:Choose individual products according to your formulation and application requirements.
Product Specification
Confirm exact grade and key specs (assay, moisture, pH, viscosity, particle size, heavy metals, microbiology, impurities) before comparing prices—product name alone is not enough.
Batch Consistency
Stable specifications across shipments reduce formulation adjustments, production variation, QC failures, and unexpected finished-product changes.
Technical Documentation
QA, R&D, and regulatory teams need Product Specification, TDS, COA, SDS, batch, packaging, and other supporting documents.
Regulatory Requirements
Food additive rules differ by country, category, and use. We provide documentation to assist with internal QA and regulatory evaluation.
Physical Form & Packaging
Consider powder/granular form, particle size, mesh, hydration, solubility, packaging size, inner liner, and palletization—the best spec works with your actual production process.
Supply Capacity
Longfeng states a production capacity of up to 5,000 tons/month and 60,000 tons/year, subject to product and scheduling—supporting regular and larger-volume requirements.
Delivery Reliability
Confirm product, quantity, packaging, lead time, shipping method, and destination. We support road, sea, and rail transportation.
