For further formulation optimization consultation, please contact HiSiaddi customer service.
Savoria, an Italian manufacturer with three mature product lines, achieved acceptable sensory and stability results in small-batch trials when switching to standard domestic national standard I+G (fixed IMP:GMP=50:50). However, mass industrial production triggered widespread defects across all three production lines, leaving approximately 1,800kg of semi-finished goods at risk of scrappage and delaying the new product launch timeline. The client previously relied on mature production processes developed for Japanese imported raw materials, lacking familiarity with differences in fermentation byproducts, crystal particle size, and enzyme sensitivity of Chinese domestic I+G. Domestic raw material producers only monitor national standard indicators such as purity and loss on drying, with no technical expertise in condiment formulation applications, attributing all finished product defects to flawed client recipes. Technical deadlock between supplier and buyer prompted the client to entrust HiSiaddi with full technical troubleshooting.
The client’s broth features a low-sodium weak acid system (pH4.1–4.4), pasteurization at 85°C, and full cold-chain storage. Standard domestic I+G contains trace fermentation residues including pyrophosphates and macromolecular polysaccharides with insufficient low-temperature solubility, forming white flocculent precipitates after 28 days of storage at 5°C. Japanese customized I+G undergoes multi-stage ion exchange impurity removal and remains fully clear under identical formulations. Uneven powder particle size of domestic I+G also causes agglomeration during direct dry powder feeding, leaving tiny white specks in the broth base.
Sauces ferment at low temperatures using fresh animal and plant raw materials containing endogenous phosphatase enzymes. Standard domestic I+G exhibits poor anti-enzymatic stability; endogenous enzymes continuously break down nucleotide structures and deplete active flavor components. Imported grades feature molecular coating modification to resist enzymatic degradation and maintain stable umami throughout shelf life. The client copied production parameters developed for Japanese raw materials without pre-treatment to deactivate enzymes, leading to severe umami loss.
When mixed with citric and malic acid for flavor adjustment, standard domestic I+G releases bitter irritant byproducts: trace free ammonium salts and heavy metal impurities precipitate in acidic environments, while partial cyclization and hydrolysis of GMP components under strong acid conditions create unpleasant bitter flavors. High-purity refined Japanese I+G undergoes strict impurity control and generates no flavor defects after organic acid compounding.
HiSiaddi deploys food ingredient application engineers and condiment formulation R&D specialists to coordinate targeted technical upgrades at domestic I+G factories upstream, fine-tune formulation parameters remotely with the Italian R&D team, and standardize workshop operating SOPs to resolve all three product defects one by one.
1. Cold-water soluble clear broth grade I+G: We coordinated factory technical upgrades adding three-stage membrane filtration, activated carbon deep adsorption, and ion exchange desalination to remove polysaccharide and pyrophosphate fermentation byproducts, reducing total impurity content from 0.62% to below 0.07%. Optimized low-temperature crystallization and air-flow grinding produce uniform 600-mesh microcrystals, boosting low-temperature solubility by 18% and eliminating low-temperature precipitation at the raw material stage. The IMP:GMP ratio was adjusted to 53:47 for a cleaner fresh flavor matching clear broth formulations.
2. Enzyme-resistant modified I+G for fermented sauces: Micro-coating modification is applied during crystallization to form a thin barrier layer on nucleotide crystal surfaces, blocking contact between endogenous phosphatase and active flavor components and drastically improving anti-enzymatic performance. Raw material moisture is strictly controlled ≤7.0% to prevent accelerated decomposition of active ingredients from moisture absorption during storage. The IMP:GMP ratio is adjusted to 47:53 for richer meaty umami suited to fermented sauces.
3. High-purity low-impurity infant-grade I+G: Two additional resin impurity removal stages are added to control free ammonium salts ≤3ppm, lead <0.4ppm, and arsenic <0.25ppm, exceeding both national standards and EU infant food limits to reduce flavor defects when compounded with acids. A balanced 50:50 ratio is retained to meet infant formula safety requirements. Factories are required to provide SGS full impurity test reports, HPLC component chromatograms, and COA quality certificates for every batch, benchmarked against internal control standards of Japanese imported raw materials.
1. Weak acid clear broth formulation: Add 0.35% food-grade propylene glycol as a solubilizer and slightly increase buffer salt dosage to stabilize pH within 4.2–4.5, reducing precipitation risks from pH fluctuations. Adjust the monosodium glutamate to I+G synergy ratio from 20:1 to 18.5:1 to optimize umami amplification efficiency.
2. Low-temperature fermented sauce formulation: Add a short 5-minute preheating step at 83°C in the early fermentation stage to deactivate endogenous phosphatase enzymes and block I+G degradation pathways. Supplement with 0.22% yeast extract to offset minor umami loss.
3. Infant seasoning powder formulation: Add trace food-grade sodium citrate chelating agent to complex trace heavy metal ions and suppress bitter byproduct formation from impurity reactions under acidic conditions. Split organic acid feeding into two stages: dissolve and cool organic acids fully before adding I+G powder to avoid localized strong acid concentration triggering raw material hydrolysis.
1. Eliminate direct dry powder feeding: Standardize pre-dissolution of I+G in 45–55°C warm water to prepare a 3% fully clear aqueous solution before pumping into mixing tanks, eliminating powder agglomeration and undissolved particles.
2. Staged feeding for high-temperature sterilized products: Add 30% of total I+G upfront for broth base mixing, then supplement the remaining 70% after sterilization once the mixture cools to 60°C, avoiding thermal decomposition and deactivation of nucleotides from prolonged high heat exposure.
3. Raw material storage protocols: Store customized I+G in cool, dry, shaded warehouses; consume all opened packaging within 48 hours to prevent moisture absorption and caking that impede dispersion performance.
4. HiSiaddi issued Italian-English bilingual operation manuals and delivered remote video training for Italian production line technicians to unify standardized feeding workflows across the entire workshop.
1. Three rounds of cross-border sample testing: 5kg air samples of each modified I+G grade were shipped to the Italian R&D laboratory for 6-month ambient shelf-life, 5°C cold storage, and accelerated strong acid compatibility stability testing. Broths exhibited no flocculent precipitation, sauces retained target umami levels, and infant powder produced no bitter off-notes; all sensory and physical-chemical indicators matched Japanese original I+G.
2. Small-batch pilot production: 600kg trial orders for each grade enabled full-process formal production trials at the client’s factory. All 1,800kg of defective semi-finished goods were reworked to meet specifications post-formulation adjustments, avoiding full scrappage losses.
3. 7 split shipments across the year: Total order volume reached 27.2 tons (10.1t broth grade, 9.5t fermented sauce grade, 7.6t infant powder grade). Goods were cleared at Shanghai Port and shipped to Genoa Port. HiSiaddi supplied full EU Clean Label documentation, non-GMO certificates, and batch test files for seamless customs clearance and warehousing.
1. Scrap losses of approximately €112,000 for semi-finished goods were avoided, and three organic condiment lines launched on schedule in Italian high-end supermarkets. New product sales rose 32% year-on-year within six months of launch. Total procurement cost of customized Chinese I+G decreased by 30.2% versus Japanese imports, while ocean transit lead time shortened from 52 days to 21 days.
2. A 31-ton annual long-term contract was renewed the following year, with additional customized R&D requests for zero-additive plant-based organic I+G. The client built an internal technical archive for domestic raw material application based on formulation and feeding specifications provided by HiSiaddi.
1. This landmark case with a European premium organic condiment brand enabled factories to complete production line processes for low-impurity, enzyme-resistant, and ratio-split customized I+G. Export premium pricing of 25% applies to high-end modified grades, and this reference client unlocked customized orders from organic food brands in Spain and Austria.
2. A quality control system for I+G targeting EU Clean Label markets was established, escaping low-price homogenization competition for standard national standard I+G in the domestic market.
1. A full technical service system covering raw material modification, downstream formulation optimization, and production process guidance for I+G was built, alongside a selection and rectification database categorized into three core application scenarios: clear broths, fermented sauces, and infant seasonings.
2. Subsequent I+G localization and technical support projects were secured from multiple mid-to-high-end organic food manufacturers in France and Switzerland.
1. Industry Pain Points: Domestic I+G manufacturers focus on mass production of standard national standard grades, only monitoring factory exit physical-chemical indicators with no R&D expertise in condiment end-formula compatibility. Mid-to-high-end overseas organic condiment brands rely on refined modified imported I+G and copy existing mature formulas and production processes directly when switching to domestic raw materials. Differences in raw material impurities, crystal morphology, and enzyme tolerance frequently trigger mass quality defects, with a technical information disconnect between raw material manufacturers and end-product clients.
2. Procurement Characteristics of Mid-to-High-End Clients: Shelf-life stability and sensory flavor performance take precedence over raw material unit price. Raw material compatibility with end formulas forms a non-negotiable procurement threshold, with zero tolerance for finished product defects including turbidity, off-odors, and umami degradation.
3. Core Value of HiSiaddi: Acting as a neutral third-party technical foreign trade service provider, we break technical barriers between upstream raw material production upgrades and downstream end-formula & mass production processes, implementing full-dimensional rectification covering raw materials, recipes, and manufacturing workflows to resolve all technical risks of domestic raw material substitution in one-stop service.
