Purchaser: PetPremium, a high-end pet nutrition group headquartered in Barcelona, Spain. It is a leading local premium pet food brand on the Iberian Peninsula, specializing in imported complete prescription diets, functional rations for breeding puppies and pregnant cats, and medical therapeutic pet food for post-operative recovery. All product lines hold Spain’s AENOR organic certification and comply with the EU FEDIAF pet feed standards. Its products are sold in high-end European pet retail chains and private animal hospitals, with no low-cost bulk OEM services. The group has long sourced high-purity original L-valine from Ajinomoto (Japan) and BASF (Germany), with an annual total L-valine procurement volume of 120 tons.
Affected by rising local European raw material prices and prolonged customized order lead times from overseas manufacturers (custom product delivery cycles exceeding 90 days), the client planned to develop exclusive customized modified L-valine in China. However, negotiations with four major domestic L-valine manufacturers—Meihua Bio, Fufeng, Jinghai and Xinghu—all stalled. Domestic factories only supply standard bulk L-valine powder complying with national standards, failing to meet five personalized customized indicators required by the client. Manufacturers were unwilling to invest in technical transformation, quoted exorbitant prices for small-batch trial samples, and set minimum order thresholds far exceeding the client’s sampling requirements, halting the customization project entirely. The client entrusted HiSiaddi with full-chain coordination to deliver the customized product.
Tailored to the client’s low-temperature wet extrusion granulation production line, intestinal sustained-release absorption technology and low-dust formulation process, the exclusive customized indicators are far stricter than national feed-grade L-valine standards:
1. Purity Customization: L-valine main content ≥99.2% (national standard ≥98.5%); optical rotation strictly controlled within a narrow range of +27.0°~+27.8° (national standard +26.5°~+28.5°); controlled impurities of by-products isoleucine and leucine ≤0.15%.
2. Dosage Form Customization: 20–40 mesh hollow sustained-release granules (conventional commercial products are 80–120 mesh fine powder) to achieve sustained dissolution in gastric acid and prevent premature decomposition and failure during granulation.
3. Coating Customization: Plant-based palm oil microcapsule coating, intact at 78°C wet granulation temperature; conventional mineral oil coating fails to meet EU organic pet food raw material access requirements.
4. Microbiological Customization: Total aerobic count ≤300 CFU/g; yeast and mold not detectable (national standard ≤1000 CFU/g), complying with sterile raw material standards for post-operative prescription diets.
5. Indicator Customization: Heavy metal lead ≤3 ppm, arsenic ≤1 ppm (national standard lead ≤10 ppm, arsenic ≤3 ppm); full-item EU SGS English COA test report required.
1. Mass production lines of leading manufacturers are designed for standard powder production. Switching to granulation and coating processes requires production line shutdown and technical renovation. Factories prioritize bulk generic orders and refuse to modify fermentation, crystallization and granulation sections for small customized batches.
2. Conventional fermentation strains produce high levels of valine impurities. Optimizing strain metabolic pathways requires dedicated R&D resources, which manufacturers allocate primarily to domestic bulk orders, rejecting niche formula optimization requests.
3. Standard products adopt mineral oil coating. Switching to food-grade plant-based coating materials requires readjustment of spraying equipment parameters and incurs additional raw material costs.
4. The client only requires a 3-ton initial trial batch, yet the minimum order threshold for individual factories stands at 15 tons. Quotations for standalone customized production rise by 45%, far exceeding the client’s procurement budget.
Leveraging years of amino acid supply chain resources, HiSiaddi selected two cooperating manufacturers for segmented production: Wuxi Jinghai (pharmaceutical-grade L-valine production line) and Fufeng Group customized pilot workshop. Jinghai undertakes high-purity fermentation and purification, while Fufeng’s dedicated pilot flexible production line operates separately without disrupting the main mass production lines, resolving production scheduling conflicts.
1. Collaborate with manufacturers’ R&D teams to optimize Corynebacterium glutamicum fermentation formulations by adjusting carbon and nitrogen source ratios to reduce by-product formation, stabilizing leucine and isoleucine impurities below 0.12%.
2. Optimize concentration and crystallization sections via gradient cooling recrystallization, locking L-valine content steadily between 99.3%–99.5% and maintaining optical rotation within the client’s specified narrow range to meet high-purity requirements.
1. Deploy wet extrusion granulation equipment in the workshop with precise control of moisture and air pressure to produce uniform 20–40 mesh hollow granules and eliminate excess fine powder.
2. Replace industrial mineral coating oil with EU-approved food-grade refined palm oil for low-temperature spray microcapsule coating. High-temperature baking tests at 80°C confirm intact coating integrity, compatible with the client’s wet granulation working conditions.
Add low-temperature irradiation sterilization post-production to reduce total aerobic count to below 220 CFU/g. Entrust SGS to conduct full-item testing per EU FEDIAF standards and issue an anti-counterfeit full English COA report. All heavy metal indicators outperform the client’s specified limits, securing testing certification for EU organic raw material access.
1. HiSiaddi consolidated small trial orders from two other niche high-end European pet food clients, raising the initial customized batch volume from 3 tons to 12 tons to meet the minimum production threshold of the flexible pilot workshop.
2. Bulk purchase coating and fermentation raw materials to cut raw material costs via volume procurement. The final unit price of customized products is 27% lower than the client’s original imported Japanese valine.
1. Sample Phase: 50kg customized samples were air-shipped to Spain for laboratory formula adjustment and three granulation pilot tests. Sustained release rate and mixing uniformity fully met standards.
2. Pilot Mass Production: The first 12 tons of customized modified L-valine were shipped to Barcelona in two sea containers with smooth customs clearance. Incorporated into mass production of three prescription pet food lines, feeding trials showed a 7.2% increase in intestinal absorption rate for lactating kittens, outperforming the original Japanese imported raw material.
3. Annual Long-Term Contract Signing: PetPremium Group finalized a 118-ton annual customized long-term contract with 8 monthly split deliveries. The client also referred two other high-end pet food brands from Portugal and Italy to HiSiaddi for customized L-valine services.
1. For Spanish PetPremium Client: Successfully completed localized customized replacement of high-end valine, drastically cutting raw material procurement costs. Production costs for its premium prescription pet food decreased by 9%, and shelf placement of its new post-operative recovery food in Southern European animal hospitals rose 32% year-on-year.
2. For Domestic Partner Manufacturers: The customized order enabled the establishment of mass production processes for plant-coated sustained-release valine, launching a new product line for EU high-end therapeutic pet food. Customized products carry a 35% export premium over standard feed-grade valine, opening access to the EU high-value therapeutic pet food raw material track.
3. For HiSiaddi Foreign Trade: Established a full-chain customized service system for valine covering strain optimization, purification customization, granule coating, third-party testing and order consolidation cost control. Subsequent customized amino acid projects were delivered for multiple mid-to-high-end nutrition enterprises in France and the Netherlands.
Major domestic amino acid manufacturers focus on mass production of standard generic products, with production lines, formulas and equipment designed to meet national standard general specifications. They exhibit low willingness for technical transformation, high minimum order thresholds and mismatched processes when faced with differentiated customized demands from mid-to-high-end overseas clients. High-end overseas pet food and nutrition brands are bound by strict EU raw material regulations and internal production line processes, making standard off-the-shelf raw materials incompatible with their formulas. Leveraging supply chain integration and industrial technical resources, HiSiaddi delivers exclusive customized solutions via flexible production scheduling, targeted process adjustment and consolidated order cost control. This enables overseas mid-to-high-end clients to achieve localized raw material replacement and cost reduction, while supporting domestic manufacturers to tap into high-value customized export markets.
