Client: SuisseBio AG, Switzerland A well-known mid-to-high-end natural health brand in Switzerland specializing in premium oral antioxidant beverages and slow-release dietary capsules, sold in high-end supermarkets and specialist pharmacies across Switzerland, France, Luxembourg and other Western European countries, complying strictly with EU EFSA food standards and cGMP production specifications. The brand had long purchased grape seed extract with total proanthocyanidins ≥90% for two product lines: liquid oral beverages and solid capsules. Half a year after mass production using the raw material, consistent quality abnormalities emerged on production lines, causing multiple finished product indicators to fail compliance standards. Internal R&D teams adjusted formulas and production parameters repeatedly yet failed to fully resolve issues, delaying new product launches. The client therefore commissioned HiSiaddi to conduct technical diagnosis and deliver a complete implementable solution.
Grape seed extract powder features strong hygroscopy, readily clumping and agglomerating in the client’s ambient-temperature production workshop. This blocked automatic feeding and conveying pipelines, triggering frequent equipment shutdowns for cleaning and drastically reducing production efficiency. Uneven powder mixing also caused excessive deviation in active ingredient content per capsule, violating quality control requirements for premium products.
When formulated into herbal beverages, the extract produced delamination and fine sediment after one week of ambient storage alongside reduced light transmittance. Beverages in transparent packaging continuously darkened under light exposure with rapid proanthocyanidin oxidation, limiting conventional shelf life to merely 45 days, far below the brand’s 12-month requirement.
Beverages underwent 82°C pasteurization while capsules used 70°C granulation drying. These two high-temperature processes caused up to 8% loss of proanthocyanidins, while the raw material’s inherent bitter astringency intensified, masking the beverage’s natural fruit flavor and failing sensory standards for premium positioning.
Polyphenols within the extract reacted with trace metal ions and thickening agents in the formula, accelerating ingredient degradation and generating micro flocculent precipitates that further destabilized finished product quality.
Partnering with manufacturer technical teams, HiSiaddi traced core root causes by cross-referencing raw material test reports, client production conditions and formula systems:
1. High powder porosity, elevated free moisture and exposed polyphenol groups enabled rapid moisture absorption and agglomeration; lack of anti-caking pretreatment rendered the raw material incompatible with continuous automated production lines.
2. Residual macromolecular polysaccharides and resin impurities in the extract reduced compatibility with aqueous systems. Proanthocyanidins contain abundant phenolic hydroxyl groups highly sensitive to light, oxygen and high temperatures; standard raw materials without stabilizing modification underwent rapid oxidative degradation.
3. Conventional extraction retained large quantities of bitter secondary metabolites amplified under high heat, while raw materials lacked heat resistance beyond process temperature thresholds.
4. Absence of ion passivation treatment on the extract allowed polyphenols to complex with trace metal ions in formulas, disrupting system balance and triggering adverse reactions.
Raw materials underwent low-temperature fluidized bed granulation to optimize particle size and reduce specific surface area, physically lowering moisture absorption. Food-grade anti-caking aids permitted under EU regulations were uniformly dispersed to eliminate agglomeration.
Low-temperature vacuum secondary drying controlled raw material moisture within 3.5%, while upgraded packaging combining aluminum foil vacuum bags, moisture-proof outer drums and built-in desiccants addressed moisture risks during warehousing and workshop temporary storage. Post-modification, powder remained loose under standard workshop conditions, enabling unobstructed automated feeding and controlling capsule ingredient content deviation within compliance limits.
Membrane separation technology removed macromolecular polysaccharides, colloids and other insoluble impurities to enhance raw material purity and water solubility, resulting in crystal-clear beverage formulations with no delamination or sediment after prolonged standing.
Molecular coating stabilization formed a protective layer around proanthocyanidin molecules to isolate light and oxygen exposure, while adjusting raw material pH to neutral ranges suppressed oxidation reactions. Testing confirmed negligible color change and over 95% active ingredient retention after 6 months of light exposure.
We assisted the client in adjusting production parameters: segmented short-duration controlled-temperature pasteurization for beverages and gradient heating capsule drying shortened raw material high-temperature exposure time, cutting proanthocyanidin loss to under 2%.
Ambient-temperature molecular taste masking adsorbed bitter substances without damaging active ingredients. Supplementary formula adjustments incorporating natural fruit flavor auxiliaries neutralized residual bitterness, delivering fresh, clean finished product taste and fully resolving sensory defects.
Specialized ion passivation processing reduced the reactivity of polyphenols prone to complexation with metal ions. We also provided auxiliary material matching recommendations, replacing reactive additives and optimizing the overall formula system to completely eliminate flocculent precipitation caused by compatibility conflicts.
HiSiaddi simultaneously issued standards for raw material storage and workshop temperature & humidity control, recommending workshop humidity maintained at 30%–40% and stable temperatures of 20–25°C, with raw materials used immediately upon opening to minimize open-air exposure. Technical specialists provided remote follow-up debugging to ensure full solution implementation.
Lab and pilot trials: HiSiaddi shipped modified trial samples for multiple rounds of client formula debugging and production line testing, resolving all identified issues with all indicators meeting EU standards and internal brand control requirements.
Mass production: Modified bulk raw materials were deployed for formal manufacturing, enabling uninterrupted automated line operation. Beverage and capsule finished products maintained consistent quality, achieving the required 12-month shelf life with compliant sensory and activity metrics.
Deepened long-term cooperation: Recognizing HiSiaddi’s technical service capabilities, the client designated HiSiaddi as its fixed grape seed extract supplier, subsequently submitting further demands including specialized low-OPC optimization and compound polyphenol raw material development, expanding bilateral collaboration continuously.
Premium daily chemical and dietary products impose far more stringent requirements on plant extracts than basic content indicators, with production adaptability, formula compatibility, stability and sensory experience all serving as core assessment criteria. Standard generic raw materials cannot match refined production workflows and high-end formula systems, while most overseas clients lack in-depth technical expertise for deep-processing plant extracts.
Beyond supplying compliant raw materials, HiSiaddi delivers end-to-end technical diagnosis, process optimization and formula guidance tailored to downstream application scenarios, comprehensively resolving technical challenges spanning raw materials to finished consumer goods. This integrated capability underpins long-term trust from mid-to-high-end overseas brands.
