Buyer: Provence Bio, a premium organic dairy enterprise headquartered in Provence, France, a leading brand of high-quality Western European dairy products. Its core offerings include organic lactose-free shelf-stable yogurt, fresh cheese and infant formula dairy products, distributed to high-end organic supermarkets and premium maternal & infant stores across France and Belgium. All products comply with EU EFSA, FCC and LFGB clean label regulations, with an annual lactase procurement volume of 18 tons. The group previously purchased lactase imported from Denmark for long-term use.
To cut raw material costs, the client replaced imported enzymes with conventional domestic powdered lactase, which triggered four major technical failures during mass production, resulting in bulk non-conforming finished goods and frequent production line shutdowns. Internal formula adjustments failed to resolve the issues, so the group entrusted HiSiaddi’s technical team to conduct full-process rectification covering raw material improvement, formula reconstruction and production process optimization.
The client adopted a closed feeding system for in-situ lactose hydrolysis in fresh milk at ambient temperature. Conventional domestic fine-powder lactase absorbed moisture and agglomerated, clogging spray pipelines and precision filters, leading to a raw material loss rate of 19.5% and 2–3 daily shutdowns for pipeline unclogging. Root cause: Domestic bulk grades are uncoated fine powder with lactose-based carriers featuring strong hygroscopicity, while imported enzymes are modified via low-temperature microcapsule granulation. The client directly applied feeding parameters designed for imported enzymes without matching the powder dispersion properties of domestic raw materials.
Hydrolysis rates fluctuated between 72% and 97% across production shifts using the same batch of raw materials, with residual sugar exceeding 0.5g/100g in partial batches, barring "lactose-free" labeling. Root cause: Conventional domestic lactase contains high levels of heteroproteins, batch-to-batch enzyme activity deviation exceeds 12%, and trace exogenous proteases are mixed in. Minor pH fluctuations in fresh milk trigger sharp activity drops.
After 7–15 days of storage, organic yogurt developed whey precipitation and sour taste, making premium products unsellable in high-end supermarkets. Root cause: Conventional lactase retains residual miscellaneous proteases that continuously break down milk proteins during fermentation and storage, destroying the yogurt emulsification system. Protein decomposition generates free amino acids that accelerate Maillard reactions and produce unpleasant off-flavors, masking natural milk aroma.
Trace bovine allergen risks emerged in the client’s zero-dairy infant yogurt formulas. EU regulations prohibit dairy-containing additives in organic infant food. Conventional domestic lactase carriers generally incorporate skim milk powder and edible lactose, conflicting with the client’s clean label formulation requirements.
1. Optimize yeast fermentation and two-stage nanofiltration purification processes to remove miscellaneous enzymes and heteroprotein impurities, limiting residual exogenous proteases and narrowing enzyme activity tolerance to ±3%.
2. Replace milk powder/lactose carriers with single-component non-GMO corn maltodextrin to achieve zero dairy and zero lactose formulations, meeting compliance requirements for organic infant food.
3. Deploy low-temperature spray microcapsule coating technology to produce spherical particles of 80–110 mesh, enhancing instant cold-water dispersibility and eliminating dust, caking and pipeline clogging at the raw material source.
1. Shelf-stable organic yogurt production line: Adjust lactase dosage downward by 16% based on incoming fresh milk pH, paired with trace food-grade sodium citrate buffer to stabilize feedstock pH at 6.3–6.5, locking lactose hydrolysis rate above 99% and residual sugar below 0.08%.
2. Fresh soft cheese production line: Split enzyme dosing into multiple stages before curd formation to shorten contact time between enzymes and casein, avoiding continuous protein breakdown by miscellaneous enzymes and eliminating whey separation in finished cheese.
3. Lactose-free infant dairy products: Adopt a high-purity refined enzyme powder compound formula and remove auxiliary buffer additives from original recipes to align with EU strict clean label controls for infant food.
1. Feeding process adjustment: Abandon direct dry powder feeding at ambient temperature. Pre-dissolve enzyme powder in 32°C clean water to prepare concentrated enzyme liquid, stir at low speed for 8 minutes before pumping into fresh milk tanks. Raw material loss due to clogging dropped from 19.5% to below 4.2%.
2. Temperature control optimization: Fix fresh milk pretreatment temperature at 36–39°C to avoid the thermal deactivation range of lactase, balancing hydrolysis efficiency and preventing the formation of undesirable flavor compounds at high temperatures.
3. Warehouse storage standards: Repackage raw materials into independent nitrogen-flushed 5kg aluminum foil bags for immediate use upon workshop opening, preventing moisture absorption and enzyme deactivation during storage.
1. Laboratory accelerated shelf-life testing: All three product lines showed no stratification or off-flavors after 45 days of constant-temperature storage, with all lactose indicators compliant.
2. Factory pilot production: 1 ton of optimized lactase was used for full-line mass production, and finished goods passed random inspection by France’s national food safety laboratory for full supermarket rollout.
1. For Provence Bio France: Stable localization replacement of imported lactase was realized, cutting comprehensive raw material procurement costs by 28.7%. Product yield rose from 73% to 99.3%, and three new organic lactose-free infant yogurt lines were launched. Domestic French sales increased by 23% within half a year.
2. For domestic partner manufacturers: A mature mass production process for zero-dairy microcapsule customized lactase was finalized based on this benchmark European order. Customized products command a 31% premium over conventional bulk grades, generating subsequent sampling inquiries from organic dairy manufacturers in Belgium and Luxembourg.
3. For HiSiaddi Foreign Trade: A closed-loop technical service model of "raw material defect diagnosis → raw material process improvement → end-product formula optimization → workshop production line rectification" was established, consolidating competitive advantages in Western European high-end food enzyme export via dairy application technical expertise.
Most domestic lactase manufacturers focus on mass production of standard grades aligned with China’s national food standards, with products featuring higher impurity levels, dairy-based carriers and poor powder morphology designed for general food applications, lacking modified specifications tailored to European high-end organic dairy requirements. Western European mid-to-high-end dairy enterprises operate automated production lines and formulations calibrated for imported modified lactase; direct substitution with conventional domestic raw materials triggers cascading issues including unstable hydrolysis, product deterioration and equipment malfunctions.
Leveraging professional technical expertise in food enzyme applications, HiSiaddi delivered full-chain solutions covering raw material modification, formula adjustment and on-site production process rectification, enabling clients to smoothly switch to domestic raw material supplies. Meanwhile, domestic manufacturers escaped low-price competition and unlocked premium European high-end food raw material markets, delivering a triple win for overseas end clients, domestic manufacturers and the foreign trade service provider.
