The cooperating client is Holland Taste, a leading mid-to-high-end food and fragrance enterprise based in the Netherlands. Its core business covers premium spirits, European bakery essences and home fragrance essential oils, with products sold across Western Europe including the Netherlands, Belgium and Germany. It partners with high-end wineries, chain bakery brands and organic fragrance stores. All product lines strictly adhere to EU food additive regulations, IFRA fragrance standards and food contact material safety specifications, with extremely stringent requirements for raw material compatibility, aroma stability, production adaptability and finished product shelf life.
The client has long purchased national standard superior-grade star anise oil for three core product categories: alcoholic essences, bakery oil pastes and liquid home fragrances. After deploying new batches of raw materials recently, recurring issues emerged including abnormal formula compatibility, aroma deterioration, high production wall adhesion loss and low-temperature pipeline crystallization. These problems reduced finished product qualification rates, triggered frequent production line shutdowns and delayed new product R&D. The client’s internal technical team failed to resolve root causes despite repeated adjustments to formulations and equipment parameters, and subsequently commissioned HiSiaddi to conduct full-dimensional technical diagnosis, formula optimization, production process rectification and on-site implementation guidance. The client required all issues to be fully resolved within 14 days to restore full-capacity stable production.
Combining raw material test reports, the client’s formula system, production line operating conditions and warehousing environment, HiSiaddi’s technical team identified four critical root causes:
1. Unbalanced aroma in compound formulations & flavor degradation during storage The core component anethole in star anise oil is susceptible to oxidation. When compounded with fruit acid and alcohol-based essences for alcoholic flavorings, chemical interactions occur. After 15 days of storage, the bright sweet aroma fades and stale off-notes develop, disrupting the overall flavor profile of spirits and failing premium liquor flavor retention standards.
2. Delamination & crystallization in bakery oil paste essences Within oil-based bakery essence systems, star anise oil exhibits poor compatibility with plant oils. After one week of ambient storage, oil phase separation occurs with fine crystals precipitating at the bottom, destroying the uniform texture of oil pastes and negatively impacting aroma release and appearance of baked goods.
3. Severe wall adhesion during feeding & elevated raw material losses The raw material’s high viscosity and surface tension cause oil to adhere to pipeline inner walls and mixing tank sides during automated pipeline conveying and open mixing operations. Single-batch production loss reaches 9.8%, inflating raw material costs and causing inconsistent active ingredient concentrations across batches.
4. Low-temperature pipeline crystallization & material blockages Workshop and raw material storage temperatures drop to approximately 12°C during Western European winters. The high solidification point of the star anise oil batch leads to gradual crystallization and thickening within sealed conveying pipelines, causing frequent blockages that force production line shutdowns for cleaning and drastically reduce operational efficiency.
HiSiaddi assembled a team of fragrance application engineers, food formulators and production process specialists. Without requiring core equipment replacement, altering the original product flavor positioning or exceeding EU safety limits, targeted optimization solutions were developed and deployed sequentially.
1. Raw material pre-treatment: Seal raw materials with food-grade inert nitrogen to isolate air and slow anethole oxidation rates, mitigating degradation risks at the source.
2. Formula optimization: Add EU-approved natural composite antioxidants to alcoholic essence systems to block oxidation reactions. Adjust compound feeding sequence: fully mix fruit acid and alcohol base materials first, cool to ambient temperature before adding star anise oil to avoid antagonistic chemical reactions under high temperatures.
3. Validation Results: After optimization, finished products retain pure aroma without off-notes after 60 days of ambient storage, with flavor attenuation controlled below 2.5%, fully meeting the 18-month shelf-life requirement.
For bakery oil paste systems, food-grade composite co-solvents and emulsifying stabilizers compliant with organic high-end food standards were selected. Mixing processes were adjusted: homogenization temperature maintained at 45°C via a three-stage mixing protocol (low-speed pre-mixing → high-speed homogenization → low-speed blending) to improve fusion between star anise oil and plant oils. Post-rectification, oil pastes remain uniform without delamination or crystallization after 90 days of static storage.
1. Process optimization: Apply food-grade anti-adhesive pre-treatment to mixing tank and pipeline inner walls; minimize raw material exposure time by adopting fully closed conveying operations.
2. Parameter adjustments: Moderately increase pipeline flow velocity and add a 3-minute wall-scraping mixing cycle at the end of blending procedures.
3. Outcome: Comprehensive raw material loss reduced from 9.8% to below 3.2%, with cross-batch component concentration deviation controlled within 0.3%, significantly improving product consistency.
1. Raw material conditioning: Blend compliant natural auxiliary materials in controlled proportions without altering aroma or violating food regulations to adjust oil crystallization properties, lowering the practical operating solidification point to below 12°C.
2. Equipment modification: Install simple constant-temperature insulation layers on conveying pipelines to stabilize pipeline temperatures at 14–16°C and prevent low-temperature crystallization. Post-rectification, pipelines operate continuously without blockages even under winter low-temperature operating conditions, enabling round-the-clock stable production line operation.
HiSiaddi engineers visited the client’s production plant to deliver hands-on training covering full workflows of flavor blending, batching, conveying and filling, clarifying standardized parameters including temperature, rotational speed, feeding sequence and operation duration. Bilingual Chinese-English operation guides were compiled to ensure long-term stable execution of optimized solutions.
1. Lab-Scale Sampling & Inspection: Five batches of lab-scale production trials were completed, with full testing of aroma, system stability, raw material loss and low-temperature fluidity. All indicators met standards, and the client’s R&D team confirmed solution feasibility.
2. Full Production Resumption: The client fully adopted revised formulas and production specifications. Over 20 consecutive production batches exhibited zero recurrence of the four core issues, finished product qualification rates recovered to 100%, and production line capacity returned to normal levels.
3. End-User Feedback: Post-launch, winery and bakery retail partners reported consistent flavor and favorable application experience, driving sustained positive end-market reputation.
· Full resolution of technical bottlenecks: The client’s existing raw material inventory was fully utilized, new product R&D schedules returned to original timelines, and reduced raw material losses directly cut production costs.
· High Client Recognition: The client’s Technical Director stated that HiSiaddi possesses in-depth expertise in the physicochemical properties of natural fragrances and European food production standards. The solutions balance practicality and regulatory compliance, addressing immediate failures while delivering long-term control recommendations, with professional capabilities aligned with the brand’s premium positioning.
· Deepened Partnership: The client designated HiSiaddi as the core supplier and exclusive technical service partner for star anise oil, expanding annual procurement volume.
