Client: UMAMI FACTORY, Japan A high-end functional condiment enterprise based in Japan, specializing in organic concentrated soup cubes, pure Japanese light soy sauce, premium compound seasoning powders, and fresh-enhancing additives for infant complementary foods. Its products are sold in high-end Japanese supermarkets, Michelin-starred restaurants and organic maternal & infant stores. The enterprise complies with Japanese JAS Organic standards, Japan Ministry of Health, Labour and Welfare Food Sanitation Act, EU EFSA regulations, Non-GMO (IP) standards and Halal requirements. It demands I+G with high purity, low impurities, pure flavor and strong thermal stability, alongside customizable ratios and particle sizes, rejecting ordinary industrial-grade products. It is a typical mid-to-high-end client focused on ultimate flavor performance.
Core pain points of the client: Existing supplier (Ajinomoto Co., Ltd., Japan) only provides fixed ratio products (IMP:GMP=1:1) with single particle sizes, high pricing and long customization lead times. The client plans to expand its Chinese supply chain and requires three differentiated customized I+G variants:
1. For premium soup stock: IMP:GMP=3:7, purity ≥99.5%, particle size 80–100 mesh, thermally stable with no decomposition at 220°C
2. For infant complementary foods: IMP:GMP=5:5, purity ≥99.8%, particle size 120–150 mesh, heavy metals ≤0.05ppm, zero miscellaneous bacteria
3. For compound seasoning powder: IMP:GMP=7:3, purity ≥99.2%, particle size 60–80 mesh, excellent flowability and anti-caking performance
The client previously collaborated with two Chinese manufacturers, yet both failed to meet requirements due to insufficient customized ratio capacity, substandard purity, imprecise particle size control and off-flavors. Worried that customized products could not meet Japan’s high-end flavor standards, the client entrusted HiSiaddi with full responsibility for customized solution design, supplier screening, process optimization, sample verification and mass production launch.
Mainstream domestic I+G manufacturers primarily produce standard 1:1 ratio products with fixed production line designs. Custom non-standard ratios (3:7, 7:3) require re-adjustment of fermentation, enzymatic hydrolysis and compounding processes. Most manufacturers decline customization due to high costs and technical difficulties. Additionally, the client requires a ratio error margin of ≤±0.5%, which ordinary factories cannot precisely control, easily causing flavor fluctuations.
Client requirements:
· Purity ≥99.5% for soup stock grade, ≥99.8% for infant food grade (national standard only requires ≥97%)
· Heavy metals (lead, mercury, cadmium) ≤0.05ppm (national standard ≤10ppm)
· Undetectable heterocyclic amines and solvent residues (zero-residue standard set by Japan Ministry of Health, Labour and Welfare)
· Pure flavor free of fermented odors and bitter aftertastes (ordinary industrial-grade I+G often carries faint off-flavors)
Ordinary manufacturers adopt traditional fermentation and crude extraction processes, with maximum purity capped at 99% and inadequate deep impurity removal, failing to meet the standards.
Particle size requirements: The three variants demand precise grading at 60–80 mesh, 80–100 mesh and 120–150 mesh with an error margin ≤±5 mesh. Ordinary manufacturers are equipped with low-precision crushing and screening equipment, resulting in uneven particle size distribution that impairs product flowability and dissolution rate.
Thermal stability requirements: The client’s soup stock undergoes high-temperature boiling at 180°C for 30 minutes, while infant complementary foods require autoclave sterilization at 121°C. Conventional I+G decomposes above 200°C with umami loss exceeding 10%, incompatible with high-temperature production processes.
Supplier screening: HiSiaddi eliminated two ordinary factories and locked in two leading manufacturers: Star Lake Bioscience (China’s top I+G producer with mature customization technology) and Meihua Holdings (industry-leading fermentation technology with flexible production capabilities). Both suppliers have long-term supply experience for Japan’s high-end market and possess non-standard ratio customization capacity.
Precise ratio process adjustment:
· Cooperated with factory technical teams to re-optimize fermentation strains and enzymatic hydrolysis parameters to boost IMP/GMP fermentation conversion rates
· Deployed high-precision compounding systems with error margin ≤0.1% to accurately blend materials at ratios of 3:7, 5:5 and 7:3
· Triple testing per batch (liquid chromatography + mass spectrometry + sensory flavor evaluation) to guarantee consistent ratios and uniform flavor
Custom high-end process route:
· Raw materials: Adopt high-purity ribose fermented from non-GMO corn starch and food-grade disodium phosphate to control impurities at the source
· Fermentation: Low-temperature precise fermentation (32±1°C) to reduce by-product generation
· Purification: Three-stage purification including nanofiltration, molecular distillation and activated carbon adsorption to remove heavy metals, heterocyclic amines and solvent residues
· Drying: Low-temperature vacuum drying (≤60°C) to avoid damage to umami substances under high heat and enhance flavor purity
Authoritative testing certification: Entrusted Japan Food Research Laboratories (JFRL) to conduct full testing per Japanese standards, issuing COA documents in both Japanese and English:
· Soup stock grade: 99.6% purity, heavy metals ≤0.04ppm, no detectable residues
· Infant food grade: 99.9% purity, undetectable heavy metals, sterile
· Seasoning powder grade: 99.3% purity, excellent flowability and anti-caking performance
Customized particle size control:
· Deploy imported jet mills and high-precision vibrating screens to precisely grade particles into 60–80 mesh, 80–100 mesh and 120–150 mesh as required
· Conduct particle size distribution testing per batch to ensure over 95% of particles fall within target ranges without mixed coarse/fine particles
Thermal stability optimization:
· Adjust crystallization processes to enlarge crystal grain size and improve crystallinity for enhanced high-temperature resistance
· Small-scale verification: Soup stock grade shows umami loss ≤2% after heating at 220°C for 30 minutes; infant food grade maintains complete integrity and unchanged flavor after 121°C sterilization, fully compatible with the client’s high-temperature processes
Flavor fine-tuning: The client requires "pure umami without off-notes, rich and lingering taste". HiSiaddi collaborated with manufacturers to extend the post-fermentation maturation period by 24 hours, eliminating faint fermented odors and boosting umami layers. Blind sensory testing conducted by the client’s Japanese sensory team confirmed superior flavor compared to equivalent Ajinomoto products.
Full compliance certification delivery: Provided Japanese JAS Organic certification, Japan Ministry of Health, Labour and Welfare food sanitation compliance documents, IP Non-GMO certificates, Halal certificates and SGS test reports, all supplied as original Japanese notarized documents to meet labeling compliance requirements for the client’s high-end products.
HiSiaddi assisted the client in applying for 1kg trial samples of the three customized I+G variants. The client completed full testing and flavor evaluation:
· Ratios: Error margin ≤±0.3%, fully compliant
· Purity & impurities: All indicators exceed client standards; heavy metals undetectable for infant food grade
· Particle size: Uniform distribution with qualified flowability and solubility
· Thermal stability: No decomposition under high-temperature testing, umami loss ≤2%
· Flavor: Pure umami free of off-notes with rich texture, highly recognized by the client’s sensory team
The client confirmed Star Lake Bioscience as the core customized supplier and placed a total order of 5 tons: 2 tons for soup stock grade, 1.5 tons for infant food grade, 1.5 tons for seasoning powder grade.
· Production cycle: 35 days for customized production, purification, screening and packaging
· Packaging: 1kg aluminum foil bags (light-proof and moisture-resistant) and 25kg food-grade fiber drums as requested, affixed with Japanese compliance labels
· Delivery: Full English/Japanese COA documents, certification certificates, batch traceability reports and flavor testing reports shipped alongside goods, passing one-time inspection by Japanese customs and the client’s quality control department
Highly satisfied with HiSiaddi’s professional technical capacity, precise customization, comprehensive compliance support and efficient delivery, the client designated HiSiaddi as its exclusive I+G customized procurement partner for the Japanese market. Subsequent customized demands including organic I+G, low-sodium I+G and compound umami enhancers (I+G + yeast extract) were added, with annual long-term cooperation volume reaching 20 tons.
For overseas mid-to-high-end clients purchasing customized I+G products, the core challenge lies not in basic manufacturing, but in full-chain customization capacity covering precise ratio control, ultra-high purity, adjustable particle size, flavor compatibility and complete compliance documentation. Ordinary manufacturers only produce standard products and cannot satisfy differentiated, extreme requirements of high-end clients.
