The purchaser is VitalPremium GmbH based in Munich, Germany, a benchmark mid-to-high-end dietary manufacturer in Germany. Its products are sold in premium organic REWE supermarkets across Germany, high-end dm drugstore lines, and national chain private health pharmacies. The company operates four high value-added product lines: sugar-free effervescent oral liquids, medicinal orally disintegrating dietary tablets, low-temperature fermented probiotic beverages, and high-end sugar-free baking meal replacements. Its raw materials comply with three access standards: EU EFSA food additive specifications, German LFGB food regulations, and USP United States Pharmacopeia, with all products positioned as zero-sucrose, high-purity excipients and clean formulas, qualifying as a typical refined production mid-to-high-end procurement client. The annual neotame procurement plan totals 6.5 tons, split into standard crystalline neotame and special modified neotame categories.
The enterprise previously purchased original US neotame raw materials long-term. Affected by rising overseas raw material prices and extended shipping cycles, it launched a domestic Chinese raw material substitution project in 2025. It first purchased three batches of standard mass-produced neotame from three major domestic manufacturers (Huatian Biotechnology, Jinhe Industrial, Luwei Pharmaceutical) for pilot production trials, yet four consecutive industrial trials exposed four critical technical failures: uneven powder mixing, sweetness attenuation of raw materials in acidic beverages, slow low-temperature dissolution, and flavor deterioration under high-temperature baking. Factories only provided standard national standard finished products, and their technical teams only mastered their own mass production processes without familiarity with the German client’s automated production line parameters and end-product formula systems, making targeted optimization of raw materials and formula matching impossible. The client’s new product launch plan stalled, with over 120,000 Euros invested in early formula R&D and production line debugging facing potential losses. After comparing multiple domestic and foreign trade service providers, the client entrusted HiSiaddi Foreign Trade, which specializes in full industrial chain technical services for sweeteners, to fully handle raw material technical diagnosis, formula optimization, production process adaptation, and full-chain technical implementation of raw material modification adjustments.
The client’s fully automated closed dry mixing feeding production line adds neotame at only 6–9 ppm via V-type closed mixers and automatic loss-in-weight feeding systems. Standard domestic neotame crystals feature uneven particle sizes and high surface static electricity, leading to severe powder agglomeration. After mixing, tablets suffer from extreme sweetness inconsistency, with RSD deviation of sweetness in the same batch exceeding 12%, far above the client’s internal qualified standard of ≤3.5%. Mass-produced neotame from the three domestic factories adopts general crystallization processes with D90 particle size ranging from 30 to 120 μm, lacking grading screening and surface modification procedures. Factories cited tight mass production schedules as a reason to refuse separate adjustments to crystallization and crushing process parameters, failing to match the client’s automated micro-feeding equipment requirements.
The client’s probiotic fruit juice has a pH value of 2.7–3.1 and requires a 12-month room-temperature shelf life. Standard national standard neotame suffers over 21% sweetness loss after 90 days of storage in this acidity system, resulting in faded sweetness and subtle bitter off-flavors precipitated by organic acids in mid-to-late shelf stages, failing quality requirements for German supermarket shelf placement. Per neotame physicochemical properties, protonation of carboxyl groups accelerates neotame hydrolysis in strong acid environments with pH＜3.2, and uncoated standard neotame cannot withstand long-term storage under low acidity. Factories only produce basic crystalline neotame without mass production technologies for cyclodextrin coating or carrier modification.
The client’s beverage batching water is consistently controlled at 8–12℃ under low-temperature aseptic conditions. Standard neotame has a room-temperature solubility of only 12.6 g/L, with drastically reduced dissolution efficiency under low temperatures. It takes over 40 minutes for 1 g of neotame to fully dissolve, leaving fine white particle suspensions in the solution that clog precision filter elements of pipelines and cause frequent production line shutdowns for cleaning. The client’s continuous production line limits single-batch batching time to a maximum of 15 minutes, making the dissolution performance of existing raw materials incompatible with low-temperature continuous production rhythms.
The client’s cookie baking process adopts 168℃ for 18 minutes of medium-high temperature roasting. Standard neotame decomposes slightly under heat to generate trace phenylalanine derivatives, producing faint burnt bitter off-flavors and approximately 13% sweetness loss, disrupting the natural milk flavor base of finished products. The client’s formula compounded with erythritol, inulin and other polyols suffers unbalanced sweetener synergy; simple adjustment of neotame addition dosage cannot resolve flavor deterioration issues. The client’s R&D team repeatedly adjusted formula ratios with no effective results, lacking practical data support for compounding neotame with functional polyols.
HiSiaddi set up a special technical team consisting of food application engineers, sweetener formula specialists, and raw material process specialists to conduct two-stage technical research:
1. Stage 1: Collect full product formulas, production line equipment parameters, and internal physicochemical standards of the client, while synchronously accessing production records, crystallization processes, and quality inspection data of the three neotame factories.
2. Stage 2: Conduct parallel lab trials at the client’s German laboratory and domestic factory pilot workshops to eliminate four variables: formula ratio, equipment parameters, excipient compatibility, and raw material quality.
Root causes of failures were ultimately confirmed:
1. The crystal structure, particle size, and surface characteristics of standard domestic neotame raw materials were not customized for the client’s application scenarios.
2. The client’s original formula was formulated around US neotame matching schemes, while domestic raw materials feature objective differences in physicochemical parameters from US counterparts, requiring simultaneous optimization of compound system ratios.
Based on investigation results, HiSiaddi selected Huatian Biotechnology, drafter of national standards, as the cooperative factory for targeted process optimization, relying on its patented neotame modification technology and customized pharmaceutical-grade production lines to deliver a dual optimization plan of raw material improvement and formula fine-tuning.
1.
Graded Modified Neotame for Orally Disintegrating Tablets The factory’s recrystallization and airflow crushing processes were optimized with gradient cooling crystallization to strictly control neotame D90 particle size within 20–24 μm. Pharmaceutical-grade mannitol was adopted for surface spray coating to eliminate powder electrostatic adsorption. Raw materials passed 120-mesh grading screening with finished powder angle of repose ≤38°, meeting free-flowing performance standards. Samples were sent to Germany for production line trials, reducing RSD fluctuation of sweetness across the same batch of tablets to within 2.9% and completely resolving uneven mixing under micro-dosage feeding.

3.
β-Cyclodextrin Encapsulated Modified Neotame for Acidic Fruit Juices A β-cyclodextrin molecular embedding process formed a protective isolation layer on the outer layer of neotame crystals to block contact with acidic aqueous environments. Accelerated aging tests (stored at pH 2.9, 37℃ for 90 days) measured only 4.1% sweetness attenuation, far below the client’s internal control limit of ≤6%, meeting the 12-month room-temperature shelf storage requirement. Internal purity standards were simultaneously optimized with main content ≥99.6% and single unknown impurity ≤0.08%, exceeding German LFGB raw material access limits.

5.
Low-Temperature Fast-Dissolving Modified Neotame A salt-forming modification process with trace food-grade phosphate composite modification drastically improved low-temperature dissolution speed. 1 g of raw material fully dissolved within 75 seconds in a 10℃ low-temperature aqueous environment without solid particle precipitation, perfectly adapting to the client’s 8–12℃ low-temperature continuous batching process and eliminating pipeline filter clogging and production line shutdown risks.

1.
Probiotic Fruit Juice Formula Optimization Based on the original formula, a trace potassium citrate buffer system slightly adjusted the pH of the product base liquid to the optimal range of 3.3–3.4 (neotame stable pH range near 4.5), matched with 0.018% β-cyclodextrin compound auxiliary agent. This adjustment preserved probiotic activity and original sweet-sour taste while further delaying neotame hydrolysis and maintaining stable sweetness throughout the full shelf life.

3.
Baking Meal Replacement Cookie Formula Optimization Recalculated compound ratios of neotame, erythritol, and inulin, replacing the single neotame addition model with a "modified neotame + acesulfame K 1:12 compound" solution, cutting total high-intensity sweetener addition by 15%. The pre-mixing process of excipients before baking was optimized for low-temperature pre-blending prior to oven entry, reducing sweetness loss to 4.8% after 168℃ roasting and completely eliminating burnt bitter off-flavors, achieving perfect integration of milk aroma and sweetness and raising sensory scores of finished products by 11 points.

5.
Fine-Tuning of Supporting Formulas for Orally Disintegrating Tablets & Effervescent Tablets Per the sweetness release curve of modified neotame, the ratios of citric acid and sodium bicarbonate in the original formula were lowered to correct acid-base balance of the effervescent system, avoiding short-term neotame decomposition caused by localized high acidity during effervescent disintegration. After optimization, no obvious sweetness change was observed for effervescent tablets stored for 6 months after opening.

HiSiaddi sent three gradient batches of optimized four types of modified neotame samples, with the client completing three rounds of implementation verification: lab trial → pilot production → industrial mass production. The pass rate of full-product line trial production rose from the original 61% to 99.3%. Small-batch trial production of 500 kg of various modified neotame variants cleared customs and shipped to Germany, supporting 72 consecutive hours of full-load production on the client’s production line with zero process failures. Meanwhile, HiSiaddi issued a German-language Neotame Feeding Operation Specification, clarifying feeding sequences, stirring speeds, and batching temperature control details for different product categories, optimizing feeding procedures for frontline operators and reducing quality fluctuations caused by human error.
1. Short-Term Implementation Benefits: After 42 days of full-process technical rectification, the client completed industrial mass production of four new products, which launched on schedule in premium REWE and dm supermarkets across Germany. Sales of sugar-free beverage and meal replacement baking single products exceeded 1.76 million Euros in the first quarter of launch. Comprehensive procurement costs of domestic modified neotame dropped by 19.2% compared with original US raw materials, significantly cutting the client’s raw material procurement expenditure. The original annual framework order of 6.5 tons was fully delivered via balanced production split into five batches.
2. Long-Term Cooperation Expansion: Building on this technical breakthrough, VitalPremium Group of Germany entrusted HiSiaddi with full responsibility for neotame and compound sweetener procurement plus technical supporting services for its subsidiaries in Austria and the Netherlands. A new customized organic carrier-coated neotame procurement demand was added the following year, expanding annual procurement volume to 10.2 tons. HiSiaddi collaborated with Huatian Biotechnology to standardize this set of modified neotame processes into mature customized product lines targeting mid-to-high-end European dietary brands, helping the factory secure multiple new high-end European export orders.
3. Factory Technical Empowerment: Relying on this project, Huatian Biotechnology accumulated mass production processes for three types of modified neotame: acid-resistant long-term storage, low-temperature fast dissolution, and micro-particle grading, completing a high-end modified neotame product matrix and filling gaps in refined production technologies matching mid-to-high-end European client standards.
Most domestic neotame manufacturers focus on standardized bulk mass production aligned with domestic general food client demands, lacking modified R&D and application supporting capabilities matching refined mid-to-high-end dietary brands in the EU, Germany and other overseas regions. They can only supply standard raw materials meeting national standards and fail to adapt to overseas automated precision production lines and special processing conditions such as low acidity, low temperature, and high temperature. European and American mid-to-high-end food enterprises formulate formula systems based on imported raw material parameters, leading to technical incompatibility among raw materials, formulas, and production lines after switching to domestic raw materials. Independent factory liaison cannot open the dual implementation path of raw material improvement and formula optimization.
With full-chain technical reserves spanning domestic raw material process R&D, food formula application, overseas regulations, and end-product production practice, HiSiaddi acts as a neutral third-party technical service provider. We optimize product properties starting from raw material crystal modification, particle size regulation, and surface coating, while assisting clients in adjusting formulas and production line processes in reverse, breaking technical barriers for domestic raw materials to access high-end European supply chains. This case intuitively demonstrates that mid-to-high-end sweetener foreign trade has long broken out of the basic model of simple commodity trading; technical empowerment, formula supporting, and process adaptation are core links connecting high-quality domestic manufacturing and overseas high-end brands. It not only helps overseas clients smoothly realize domestic raw material substitution, control production costs, and guarantee new product launch schedules, but also supports leading domestic sweetener manufacturers to break away from low-end homogeneous mass production tracks and access the global mid-to-high-end food raw material supply chain system.
