The buyer is NATURWELL Natural Health Group, headquartered in Amsterdam, Netherlands. With 27 years of expertise in developing and producing high-end clinical dietary supplements, organic meal replacement powders and postoperative rehabilitation nutritional powders for Western Europe, its products are supplied to nutrition departments of Dutch public hospitals, high-end organic supermarket chains across Northern Europe and wellness sanatoriums in Belgium. All raw materials comply with EU-ORGANIC, USDA organic, BRCGS, IFS, EU MRL pesticide residue limits, California Proposition 65 control, as well as KOSHER and HALAL dual certifications. Its flagship product lines include fully organic additive-free powders and plant hard capsules. It rejects low-cost algae powder from scattered open-field cultivation and bulk composite raw materials blended with starch, standing as a typical mid-to-high-end raw material purchaser in Europe. The group maintains a fixed annual purchase volume of 38 tons of Spirulina-Chlorella composite powder at a customized Spirulina:Broken-cell Chlorella ratio of 62:38, used for self-developed high-end meal replacement powders and rehabilitation nutritional capsules. It previously imported finished blended powder from Danish organic algae manufacturers long-term.
Driven by skyrocketing algae cultivation costs in Northern Europe, raised minimum order quantities by overseas factories and extended shipping cycles of up to 88 days, the client launched a domestic China raw material substitution project in 2025. It independently sourced standard blended algae powder from three leading domestic manufacturers (Fujian New Daze, Yunnan Green Algae Bio, Shandong Blue Algae Industry). When applying domestic raw materials to its mature European terminal formulas for mass production, five major production failures emerged: poor powder fluidity causing blockages in automatic canning, aggravated fishy odor and oxidative discoloration of finished products during storage, stratification and precipitation upon cold-water brewing, mold adhesion and excessive disintegration rate during capsule tableting, and excessive batch-to-batch fluctuations in nutritional indicators. Three finished product production lines of the client suspended operation for debugging, incurring total losses of 79,000 EUR from auxiliary material waste, semi-finished product scrapping and laboratory sample testing consumables. The launch of its new organic rehabilitation meal replacement powder scheduled for autumn was postponed. The three raw material manufacturers only guaranteed compliance with basic protein content standards, specializing in mass production of general health supplement-grade products without R&D capabilities for downstream terminal formula applications. They failed to conduct targeted product optimization from the perspectives of raw material physical properties, blending processes and algae powder pre-treatment despite multiple minor sample adjustments. NATURWELL Group of the Netherlands therefore fully entrusted HiSiaddi to take full charge of fault tracing, raw material formula optimization, upstream production process rectification and lightweight terminal formula fine-tuning across the whole technical service chain.
Mandatory Technical Standards for Client Products (Far Exceeding National Standard Universal Algae Powder)
1. Fixed blending ratio: Spirulina 62% + Broken-cell Chlorella 38%; crude Spirulina protein ≥63%, broken-cell Chlorella protein ≥52%, Chlorella cell breaking rate ≥98.3%; batch-to-batch fluctuation of chlorophyll and phycocyanin ≤±2% to meet EU regulations on nutritional labeling of finished products.
2. Powder angle of repose ranging from 29° to 31°, 100% passing through 120-mesh sieve; moisture absorption weight gain <1.1% after 72 hours under 65% RH high-humidity environment, compatible with fully automatic high-speed canning and hard capsule tableting equipment.
3. Uniform dispersion in cold water within 30 seconds with no precipitation or floating residues; free of native pond putrid fishy odor; no oxidative yellowing or fat rancidity after 18 months of sealed light-proof storage at room temperature.
4. Contents of heavy metals, microcystins and pesticide residues all below EU EC1881 limit standards; no additional maltodextrin, silicon dioxide or other anti-caking auxiliary materials added throughout the whole process.
Collaborating with algae R&D engineers, HiSiaddi fully analyzed multiple batches of unqualified finished product test reports and incoming raw material quality inspection data from factories, breaking down the root causes of mismatches between domestic raw materials and terminal formula mass production. All failures stemmed from misalignment between upstream algae powder production processes, blending techniques, raw material pre-treatment and the client’s original terminal formula:
Universal composite powder mass-produced by the three factories featured an angle of repose ranging from 38° to 44°, uneven powder particle sizes and excessive fine powder content, leading to inconsistent self-weight feeding of raw materials. The client’s high-speed canning equipment required shutdown and silo cleaning every two hours, while capsule tableting molds frequently experienced powder adhesion, resulting in capsule filling weight RSD >5% (exceeding the EU Pharmacopoeia control standard of ≤3%) and large quantities of defective empty or underfilled capsules. Manufacturers only adopted conventional crushing processes without airflow classification modification procedures, designing powder physical properties for low-cost mass-market health supplements incompatible with high-end automated production lines.
Standard algae powder only underwent simple hot air drying without deodorization treatment for ketone and alkane odor-causing substances within algae cells. Raw materials carried earthy and pond putrid odors; after 30 days of sealed finished product storage, trace unsaturated fatty acids in algae powder gradually oxidized and decomposed, worsening the fishy odor and failing European terminal sensory acceptance standards, triggering soaring return rates from supermarkets.
Outdated Chlorella cell breaking technology in standard products delivered a cell breaking rate of only 85%~89%. Intact hard cell wall particles from unbroken cells failed to dissolve in cold water, causing rapid sinking and stratification after blending with Spirulina powder. Water-soluble phycocyanin from Spirulina easily precipitated under low temperatures, rendering the client’s low-temperature meal replacement formula non-compliant. Multiple adjustments to thickener dosage in the formula failed to eliminate precipitation fundamentally.
Spirulina and Chlorella are rich in chlorophyll and unsaturated lipids. Conventional open-air drying processes exposed algae powder to oxygen for pre-oxidation. After blending, finished products gradually turned dark brown from dark green after two months of light-proof storage, with degradation of active nutritional substances and a chlorophyll loss rate exceeding 12%, failing to meet the client’s 18-month shelf-life storage requirement.
Factories utilized fixed large-tank stirring equipment for mass blending, relying on rough manual feeding to achieve the customized 62:38 ratio without precise layered pre-mixing procedures. Differences in protein and chlorophyll values between sampling points within a single batch exceeded 4%, resulting in inconsistent nutritional test results for the client’s finished products and failure to pass filing reviews by Dutch food regulatory authorities.
HiSiaddi formed a team of algae raw material process engineers and formula R&D specialists stationed at factories, splitting solutions into two modules: upstream raw material production technical transformation and lightweight fine-tuning of the client’s terminal formula. All adjustments were implemented without altering the core framework of the client’s original formula over a 42-day period to finalize sample specifications.
Two manufacturers were selected from the three candidates: Fujian New Daze (organic Spirulina cultivation base) and Yunnan Green Algae Bio (high-end Chlorella deep processing workshop). The two raw materials were produced separately at different bases before unified precise blending in a dust-free workshop, with targeted optimization of five production sections item by item:
1. Precise Metered Layered Blending Renovation: Deploy a closed three-dimensional tumble blending system for pilot trials with two rounds of layered pre-mixing. A small quantity of base algae powder was added first as the substrate, followed by precise batch feeding of remaining powder under full automatic weighing control to lock the 62:38 fixed ratio, achieving mixing uniformity RSD <1.8% and completely eliminating batch-to-batch fluctuations in nutritional data.
2. Chlorella Cell Breaking Process Upgrade: The Yunnan base replaced equipment with ultra-high-pressure low-temperature homogeneous cell breakers for segmented ambient-temperature cell breaking, stabilizing the Chlorella cell breaking rate at 98.5%~99.1%. Fully crushed hard cell walls greatly improved cold-water solubility and eliminated the root cause of precipitation and stratification.
3. Low-Temperature Enzymatic Deodorization + Nitrogen-Sealed Drying: A compound protease low-temperature enzymatic section was added to directionally decompose fatty acids and heterocyclic compounds triggering fishy odors in algae powder. Nitrogen-sealed low-temperature vacuum drying was adopted during drying to avoid high-temperature oxidation and odor generation, delivering finished products free of native putrid fishy odors and fundamentally improving sensory defects of raw materials.
4. Airflow Classification Powder Modification: Multi-stage airflow crushing and classification were applied post-drying to screen uniform 120-mesh powder, removing oversized coarse particles and ultra-fine dust to optimize powder stacking structure. The angle of repose stabilized at 29.5°~30.8%, with moisture absorption weight gain controlled within 1.0% under high-humidity environments, fully compatible with the client’s automated canning and tableting equipment and eliminating blockage and mold adhesion failures.
5. Antioxidant Sealed Production Control: The entire production process adopted closed negative-pressure operation, with finished products filled with nitrogen before sealed packaging to block chlorophyll oxidative degradation in algae powder. Accelerated stability tests confirmed no obvious color change of finished products after 18 months of room-temperature storage, with nutritional loss controlled within 3% to meet long-cycle warehousing and distribution requirements across Europe.
Minor adjustments to auxiliary materials were proposed on the premise of retaining the core raw material ratio of the client’s original formula without disruptive formula overhauls:
1. Meal Replacement Powder Formula: Reduce the original dosage of xanthan gum and pectin thickeners by 0.15%. Leveraging the excellent dispersibility of optimized algae powder, excessive colloids were no longer required to achieve uniform cold-water suspension, reducing thick, cloying mouthfeel of finished products. Feeding sequence of the formula was fine-tuned: pre-blend composite algae powder with inorganic salts first before adding fruit and vegetable powder and vitamin components to avoid local flocculation and precipitation of algae protein upon contact with acidic auxiliary materials.
2. Capsule Filling Formula: Trace silicon dioxide anti-caking agent was removed from the original formula. High-flow modified algae powder enabled direct filling, aligning with the client’s fully organic zero-additive product positioning and lowering compliance risks of finished products. Capsule filling weight error was stably controlled within 2.0%.
After process optimization and specification finalization, 3 batches of lab samples and 2 batches of 300kg pilot mass production were completed. All samples underwent full-item testing by SGS in accordance with EU organic standards and were sent to the client’s R&D laboratory in the Netherlands for full actual measurement of canning, tableting and brewing. All indicators successfully passed the client’s acceptance confirmation.
The full-year 38 tons of composite powder were split for staggered production scheduling: the first trial production batch of 6.2 tons delivered priority shipment, with the remaining 31.8 tons divided into 9 batches produced monthly in staggered cycles. HiSiaddi conducted on-site sampling and retention inspection before delivery of each batch, issuing bilingual Chinese-English COA quality inspection reports, cultivation traceability records and a full set of EU compliance qualification documents. The first batch of goods was shipped from Xiamen Port to Rotterdam Port, the Netherlands, with all documents submitted to Dutch customs for pre-review in advance for one-time smooth customs clearance upon arrival. Raw materials were directly fed into full production lines on-site, resuming full-load operation of three suspended production lines. The high-end meal replacement new product whose launch had been delayed for three months was successfully rolled out across organic supermarket chains and public hospital nutrition departments nationwide in the Netherlands.
Compared with the original Danish imported raw materials, the client’s overall procurement cost decreased by 25.2%, while ocean delivery cycles were shortened from 88 days to 37 days, greatly improving supply chain turnover efficiency.
1. NATURWELL Group of the Netherlands fully terminated import channels from Danish manufacturers, switching 100% of its annual 38-ton composite powder sourcing to China via HiSiaddi. In the following year, the client added a low-dust ultra-fine algae powder composite new product exclusively for pregnant women, with an additional annual purchase order of 13.5 tons.
2. The client entrusted HiSiaddi with exclusive overall coordination of China procurement and formula technical planning for more than ten types of organic plant raw materials including euglena powder and barley grass powder. Drawing on the results of this process optimization project, HiSiaddi assisted Fujian New Daze and Yunnan Green Algae Bio in perfecting standardized production processes for EU-grade high-end blended algae powder, successfully developing two equivalent high-end nutrition brands in Finland and Sweden.
Leading domestic Spirulina and Chlorella manufacturers boast mature large-scale cultivation, yet production line processes, blending parameters and deep processing schemes are benchmarked against low-cost mass-market domestic health supplements, only controlling basic indicators such as protein content without supporting auxiliary technologies including powder modification for high-end EU preparations and meal replacement formulas, deep deodorization and precise blending. Mid-to-high-end overseas dietary enterprises possess mature finished product formulas but lack familiarity with technical shortcomings of domestic algae powder production processes. Switching to domestic raw materials frequently triggers mass production failures, delayed new product launches and excessive production loss of auxiliary materials.
Breaking away from the traditional foreign trade model limited to raw material intermediary sales, HiSiaddi positions itself as a third-party technical service provider, connecting two-way technical service chains covering upstream cultivation and production process optimization and downstream terminal formula adaptation fine-tuning. It not only resolves mass production technical challenges for mid-to-high-end European clients and recovers economic losses from production suspension, but also assists premium domestic organic algae manufacturers in escaping low-price competition for bulk raw materials and entering the high-value EU organic dietary raw material track, delivering long-term win-win results for both supply and demand sides.
