The buyer is NutriPremium SAS, a leading mid-to-high-end dietary raw material purchaser based in France. Its products are sold in premium organic sections of Carrefour France, national pharmacy chains in France, and infant complementary food counters in Belgium. The company focuses on three core product lines: organic plant-based beverages, premium sports nutrition powders, and medical oral nutrient solutions. Its raw materials must comply with six stringent standards: USP Pharmacopoeia, EP European Pharmacopoeia, LFGB, EU Organic Regulation (EU) 2018/848, Kosher and BRC Global Food Safety Standard. The group plans to custom-purchase 110 tons of bio-based high-purity L-lactic acid annually.
Unlike conventional 80% and 88% lactic acid widely available on the market, the client required three non-standard customized specifications that could not be directly produced on regular mass production lines of major domestic lactic acid manufacturers (Jindan Technology, Sanjiang Good). The customized project stalled for nearly one month before the client entrusted HiSiaddi to fully manage the entire customized development process.
1. Custom Concentration: Reject the industry-standard 80%/88% liquid specifications; customize L-lactic acid with an exact solid content of 72.5% ±0.3% and acidity fluctuation ≤±0.1%. This matches the client’s automatic online pH closed-loop regulation system for beverages, a stability target hard to achieve with conventional concentration/dilution processes.
2. Custom Configuration & Purity: Optical purity of L-lactic acid ≥99.7%, D-lactic acid isomer content ≤0.12%, internal control limits for heavy metals (lead, arsenic, cadmium) set at 50% of national standards, APHA color ≤15, and no filter aids added at all to meet clean label regulations for infant nutrient solutions.
3. Custom Raw Materials & Packaging: Fermented exclusively from non-GMO sugar beet with full organic traceability; replace standard 25kg plastic drums with sterile IBC totes lined with food-grade EVOH barrier film to block light and prevent oxidation, ensuring no discoloration or deterioration after 6 months of low-temperature storage in France.
Major domestic lactic acid manufacturers operate standardized mass production lines calibrated for common 80% and 88% lactic acid. Retooling production lines for trial runs entails high costs, and manufacturers lack translation support and compliance expertise for overseas customized specifications. Three batches of samples produced by multiple factories failed to meet standards, suffering from excessive concentration deviation, out-of-spec isomer content, and yellow discoloration during storage. Factories only supply off-the-shelf products per their internal standards and are reluctant to invest in R&D and production adjustments for niche customized grades.
HiSiaddi formed a dedicated team of lactic acid technical engineers, compliance specialists and production coordinators to liaise with two leading domestic lactic acid producers, Jindan Technology and Sanjiang Good. The full customized development cycle from lab samples to pilot production to mass production was completed in 22 days across four phases:
1. Collaborated with the manufacturer’s R&D department to adjust fermentation strains by selectively culturing high-L-configuration lactobacilli with segmented temperature and pH control during fermentation, limiting D-lactic acid by-products to below 0.1% at the source.
2. Revised downstream refining processes: replaced traditional single-stage concentration with multi-stage low-temperature membrane filtration + precise vacuum rectification, substituting high-temperature concentration. The lactic acid was slowly blended to an exact concentration of 72.5%, with real-time online solid content monitoring per batch to stabilize acidity fluctuations and resolve inconsistent concentration issues.
3. Added two-stage activated carbon ultrafiltration purification to remove trace pigments and heavy metal impurities, stabilizing the APHA color of finished products at ≤12 to satisfy low-color storage requirements.
1. HiSiaddi coordinated with domestic sugar beet planting bases recognized by France to secure exclusive batches of non-GMO beet raw materials. A five-level traceability file system covering beet cultivation, sugar production, fermentation, lactic acid refining and finished product filling was compiled, with each raw material batch linked to farm IDs, harvest documents and incoming quality inspection records.
2. Assisted the manufacturer in physically isolating dedicated customized production lines with separate fermentation tanks and refining pipelines for organic raw materials to avoid cross-contamination with conventional corn-based raw materials. EU-recognized organic filing procedures were completed, alongside COI organic certification documents.
Coordinated packaging manufacturers to develop custom sterile food-grade IBC totes with inner high-barrier light-blocking EVOH liners. Tote bodies were printed with bilingual French-English product parameters, E296 additive codes, traceability batch numbers and EU importer registration information, replacing standard PE drums to prevent oxidation and discoloration during transportation and storage.
Custom COA test reports compiled in accordance with the European Pharmacopoeia and French food laws, with additional specialized testing for isomers, heavy metals and color as specified by the client for every batch. A full set of foreign trade documents including CNAS-accredited third-party test reports, SDS safety data sheets and organic traceability archives was provided.
1. Laboratory samples (500ml): After three rounds of process fine-tuning, all indicators met specifications. Samples were sent to the client’s French laboratory for formula compatibility testing, with no abnormal pH, precipitation or discoloration observed during production trials of three end products.
2. Pilot production samples (1.2 tons): Small-batch manufacturing on dedicated factory lines passed accelerated stability testing (90 days storage at 5°C) conducted by the French client, with no changes to product color or concentration.
3. Mass Production Launch: After full qualification confirmation, the client signed an annual framework order for 110 tons of customized lactic acid, scheduled for monthly production across 9 batches and shipped in custom IBC totes by sea.
The first shipment of 13 tons of customized lactic acid departed Shanghai Port for Le Havre Port. French customs verified product parameters, organic traceability records and compliance documents without discrepancy, enabling fast customs clearance and warehousing. The client launched full operation of its three premium production lines, with finished product defect rates dropping from 18.6% (when using conventional lactic acid) to under 0.5%.
1.
French Mid-to-High-End Client Customized lactic acid enabled mass production of new products, with three organic beverage lines launched across premium Carrefour stores nationwide in France. End product premium pricing increased by 31% compared with formulations using Dutch imported lactic acid. Using the customized standard template provided by HiSiaddi, the client established internal enterprise specifications for special lactic acid raw material incoming inspection, cutting the R&D cycle for future new product raw material customization by 55% and significantly reducing sample testing losses. In the following year, the client expanded into premium nutrition channels in Spain and Portugal, placing an additional 46 tons of customized lactic acid orders to bring total annual procurement volume to 156 tons, awarding all lactic acid customization orders exclusively to HiSiaddi.
