The purchaser, FruitVita Srl of Italy, is a leading mid-to-high-end natural fruit and vegetable beverage enterprise in Southern Europe. Its products are sold in high-end organic Coop supermarkets across Italy, Swiss health supermarket chains and premium beverage specialty stores in Austria. The company operates three core product lines: NFC not-from-concentrate fruit and vegetable puree, low-acid organic sparkling drinks, and natural fruit drop supplements for children. All products comply with multiple access standards including FCC, USP, EU EFSA additive specifications, EU Organic Regulation 2018/848, Kosher certification and BRC Grade A food safety standards. The enterprise previously imported food-grade L-malic acid from Spain year-round. Affected by annual price hikes of European raw materials and seasonal production capacity shortages, it launched a China customized procurement project in 2025, with total annual customized procurement volume of L-malic acid reaching 108 tons.
The client’s self-developed formulas were incompatible with standard domestic DL-malic acid and conventional L-malic acid available on the market, requiring three differentiated non-standard customized indicators. The client previously independently contacted four major domestic malic acid manufacturers (Changmao Biochemical, Nanjing Adufu, Anhui Huabang and Jiangsu Ruibang). All mass production lines of domestic manufacturers were set up for standard specifications, mainly producing conventional granules and powder widely circulated in the market. Manufacturers faced high technical renovation costs for production lines and preferred spot goods delivery, refusing to separately adjust fermentation, refining and crystallization processes for niche high-end formulas. Four rounds of sample delivery all failed, resulting in problems such as browning of finished fruit juice, crystal precipitation of beverages under low temperature, and astringent taste of children’s drops. High raw material scrap costs were incurred during mass production trials, putting the new product launch plan on hold. After failing to find manufacturers willing to conduct technical rectification, the client formally entrusted HiSiaddi Foreign Trade to fully coordinate customized R&D of raw materials, production line renovation, pilot mass production and full-chain compliance support delivery.
1. Configuration & impurity customization: Only natural L-malic acid produced via microbial fermentation is allowed; chemically synthesized DL-type is prohibited. Optical purity of L-malic acid ≥99.8%, fumaric acid residue ≤0.02%, maleic acid not detected. Heavy metals including lead, arsenic and cadmium are controlled within 50% of FCC standard limits to meet clean label requirements for infant and toddler products. Standard commercial products generally contain 0.1%–0.3% fumaric acid, failing to meet low-temperature stability requirements for beverages.
2. Customized crystal forms and particle sizes for three dedicated product grades ① Ultra-fine water-soluble micropowder with D50=20μm (for children’s fruit drops): Instantly fully soluble in cold water, no crystal precipitation during long-term storage at 4°C under weak acid conditions; ② Hollow regular crystalline granules of 30–60 mesh (for NFC puree): Fast dispersion during feeding, resistant to agglomeration, and will not accelerate fruit juice browning during high-temperature instantaneous sterilization; ③ Slow-release coarse crystals of 12–20 mesh (for organic sparkling beverages): Slow acid release, limiting pH fluctuation of beverages within ±0.06 throughout shelf life.
3. Customized raw material traceability & packaging: Raw materials limited to non-GMO corn sugar for fermentation, with full-chain raw material traceability archives retained. Conventional 25kg kraft plastic composite bags are replaced with customized food-grade aluminum foil vacuum inner bags to isolate air and prevent moisture oxidation, adapting to high-temperature storage environments in southern Italy.
HiSiaddi assembled a team of organic acid engineers, food formulation specialists and compliance specialists, screened two source manufacturers (Changmao Biochemical and Nanjing Adufu) with flexible customized technical renovation capabilities, and set up independent isolated dedicated production lines to avoid cross-contamination with general DL-malic acid. Optimization was implemented across four key links: fermentation regulation, multi-stage refining, fractional crystallization and customized packaging.
1. Guide manufacturers to select specialized acid-producing strains, precisely regulate fermentation dissolved oxygen and temperature to reduce by-product fumaric acid generation from the source;
2. Add a three-stage Simulated Moving Bed (SMB) separation unit combined with low-temperature activated carbon deep impurity removal section to replace traditional single crystallization processes, accurately removing maleic acid and trace heavy metals. Tested finished products achieved fumaric acid content of 0.015% and optical purity of 99.86%, both exceeding the client’s customized thresholds.
1. Ultra-fine powder for children’s drops: Adopt low-temperature airflow pulverization and closed graded screening to strictly control D50=20μm, eliminating coarse particles and meeting stability standards for weak acid low-temperature systems;
2. 30–60 mesh crystals dedicated to NFC fruit juice: Adopt stepwise slow cooling crystallization to generate hollow porous crystals, accelerating dissolution during feeding and reducing triggers for fruit juice browning under high-temperature processing;
3. 12–20 mesh coarse crystals for sparkling beverages: Extend crystal ripening time to produce large-particle crystals with reduced dissolution rates, enabling slow acid release and stabilizing beverage pH throughout shelf life.
1. HiSiaddi coordinated designated non-GMO corn deep processing bases to establish full-batch traceability ledgers covering corn raw materials → glucose solution → fermentation → refining → finished products, with one-to-one correspondence between raw material batch codes and finished goods, and issued EU-recognized organic traceability documents;
2. Cooperate with packaging manufacturers to customize inner aluminum foil composite food bags with light and oxygen barrier properties. Barrels are printed with bilingual Italian-English product information, E296 additive code, raw material sources and allergen prompts, complying with EU Label Regulation (EU) No 1169.
Issue bilingual English-Italian COA quality inspection certificates in accordance with FCC and EU standards, accompanied by third-party CNAS test reports, SDS safety data sheets, batch-specific Kosher sub-certificates and organic compliance statements to facilitate customs clearance in Italy and local product filing.
HiSiaddi delivered samples in three batches sequentially: 500g laboratory samples → 60kg pilot samples → 1-ton mass production trial materials. The client’s R&D center in Italy conducted formula compatibility, accelerated stability and full-scale production line tests. All three customized raw materials passed inspection, completely eliminating previous issues including browning, crystal precipitation and unstable acidity. The client signed a 108-ton annual framework procurement order: 35 tons of ultra-fine water-soluble powder (infant and toddler drops), 42 tons of 30–60 mesh crystals (NFC puree), and 31 tons of 12–20 mesh coarse crystals (sparkling beverages), with monthly scheduled shipments across 12 batches per year. The first batch of goods was shipped from Shanghai to Naples Port and cleared customs in one go, enabling full operation of the client’s three production lines and timely launch of new products in high-end supermarkets across multiple Southern European countries.
In the second year of cooperation, the client expanded into high-end beverage markets in Greece and Croatia, adding 36 tons of customized malic acid procurement, bringing total annual procurement volume up to 144 tons. All organic acid procurement and customized development projects under the brand were fully entrusted to HiSiaddi for coordination.
Procurement costs of domestically customized L-malic acid decreased by 27.3% compared with raw materials imported from Spain. The three lines of organic beverages achieved a 32% terminal price premium versus competing products using imported raw materials. Relying on raw material acceptance standards sorted out by HiSiaddi, the client established internal control specifications for organic acid warehouse incoming inspection, cutting subsequent R&D cycles for new product raw material customization by 55% and drastically reducing sample scrap costs.
Supported by this high-end European customization project, the two manufacturers completed technical renovation of refined L-malic acid production lines and improved quality control systems aligned with FCC and EU organic standards. With this successful case as a reference, they successively secured designated orders from three high-end beverage enterprises in Portugal and Slovenia, successfully entering the high-end organic acid supply chain in Southern Europe and escaping low-price cutthroat competition focused on low-end DL-malic acid.
Breaking away from the traditional spot goods price-difference trading model, HiSiaddi built integrated service capabilities covering customized process implementation, particle size modification, traceability control and full-set compliance support. Relying on technical barriers in customization, the enterprise established deep binding ties with mid-to-high-end European food clients and formed differentiated competitiveness in the organic acid category.
Most domestic malic acid manufacturers focus on mass production of low-cost DL-malic acid and standard L-malic acid with fixed production line processes. Their R&D priorities lie in cost reduction and capacity expansion, lacking refined crystallization and graded crushing supporting production lines tailored for high-end European and American beverages, as well as technical reserves for overseas customized regulations and formula application. High-end organic beverage brands in Europe and America feature highly refined formulas; minor deviations in raw material impurities, crystal forms and particle sizes can lead to finished product failure. As a neutral foreign trade service provider, HiSiaddi connects upstream production technical renovation and downstream end customized demands, bridging process and information gaps between China and foreign markets. The enterprise not only helps overseas high-end clients achieve localized procurement with cost reduction, but also supports high-end domestic malic acid to successfully enter the high-end ingredient market in Europe.
