The cooperating client is SwissAroma, a well-known mid-to-high-end brand in Switzerland specializing in organic aromatherapy essential oils, luxury aromatherapy candles and high-end Western food flavorings. Its products cover premium European markets including Switzerland, France and Italy, fully complying with IFRA fragrance standards, EU food additive regulations and organic product specifications with stringent requirements for raw material compatibility, aroma stability, production adaptability and finished product shelf life.
The client has long purchased food-grade cinnamon oil for three product lines: warm-toned aromatherapy essential oils, aromatherapy candles and Western sauce flavorings. After deploying new batches of raw materials, recurring issues emerged including aroma deterioration, material stratification, severe wall adhesion during production leading to high raw material loss, and low-temperature pipeline crystallization blocking, causing frequent production line shutdowns and stalling new formula R&D. Internal technical teams adjusted parameters multiple times without fundamental resolution, prompting the client to entrust HiSiaddi with problem diagnosis, formula optimization, process rectification and on-site guidance, requiring complete resolution within 13 days to restore full stable production capacity.
Combining raw material testing, the client’s formula system, production operating conditions and warehousing environment, HiSiaddi’s technical team identified four core root causes:
1. Aroma susceptible to oxidative deterioration and disrupted fragrance balance Cinnamaldehyde, the primary component of cinnamon oil, is chemically active and prone to oxidation upon exposure to air and light, generating irritating acidic substances. When blended with plant essential oils and lipids, the mild sweet cinnamon notes fade within roughly 20 days of finished product storage, replaced by rancid off-odors that ruin the overall fragrance profile, failing to meet aroma retention requirements for premium aromatherapy products.
2. Poor compatibility in oil-based sauce systems leading to stratification and precipitation In Western oil paste sauce systems, cinnamon oil exhibits insufficient miscibility with vegetable oils, resulting in floating oil phases and fine bottom crystallization after one week of ambient storage, creating uneven paste texture that compromises food taste and appearance quality.
3. Severe wall adhesion during feeding leading to high raw material loss Cinnamon oil features relatively high viscosity. The client adopts open stirring kettles and long-distance pipeline transportation, causing oil to adhere to equipment inner walls, with a single-batch production loss rate reaching 10.2%. This not only increases costs but also triggers deviations in active ingredient content across batches, reducing product consistency.
4. Low-temperature crystallization blocking pipelines and halting production Workshop and warehouse temperatures drop to approximately 11℃ during autumn and winter in Europe. The solidification point of the cinnamon oil batch in question is excessively high, leading to gradual crystallization and sharp viscosity spikes inside sealed transport pipelines, frequent pipeline blockages and mandatory production line shutdowns for cleaning, drastically cutting production efficiency.
Collaborative work between HiSiaddi’s flavor application engineers, food formulators and process specialists delivered targeted solutions for each issue without replacing main production equipment, altering the original product flavor profile or exceeding EU safety limits.
· Raw Material Pre-treatment: Inventory cinnamon oil is hermetically sealed with food-grade nitrogen to isolate oxygen and slow cinnamaldehyde oxidation from the source.
· Formula Optimization: EU-approved natural composite antioxidants are incorporated into aromatherapy and flavoring systems; the feeding sequence is adjusted to add cinnamon oil only after base materials cool to ambient temperature to avoid accelerated component reactions under high heat.
· Packaging Recommendations: Finished aromatherapy essential oils and aromatherapy candles are uniformly switched to dark brown light-proof containers to block light-induced degradation.
After optimization, finished products retain pure aroma without rancidity after 90 days of ambient storage, with flavor attenuation controlled within 2.8%, meeting the 24-month shelf life standard.
Multiple food-grade compliant solubilizers and emulsifying stabilizers were blended to align with organic food standards. Meanwhile, stirring processes were adjusted: homogenization temperature set at 48℃ with a three-stage stirring protocol of "low-speed pre-mixing – high-speed homogenization – low-speed blending" to boost miscibility between cinnamon oil and vegetable oils. After rectification, oil paste sauces remain uniform without stratification or crystallization after 90 days of static storage.
· Equipment Modification: Food-grade anti-stick coating is applied to inner walls of stirring kettles and transport pipelines; airtight gas collection devices are installed at feeding ports to reduce oil volatilization and adhesion from exposed surfaces.
· Process Adjustment: Pipeline flow velocity is increased, and a dedicated 3-minute wall-scraping stirring step is added at the end of mixing procedures; the duration of raw material exposure and transfer is shortened.
After rectification, the comprehensive raw material loss rate dropped below 3.1%, with cross-batch ingredient content deviation ≤0.3%, significantly improving product consistency.
· Raw Material Blending: Compliant natural homologous fractions are blended per food and fragrance regulations to fine-tune the oil’s crystallization characteristics, lowering the operational solidification point below 12℃.
· Equipment Optimization: Thermal insulation layers are installed on transport pipelines to maintain a stable pipeline temperature of 14~16℃.
After rectification, pipelines operate continuously without crystallization or blockages under low-temperature working conditions, enabling round-the-clock stable production line operation.
HiSiaddi engineers traveled to the client’s production plant to deliver hands-on training covering full procedures including batching, stirring, transportation and filling, standardizing parameters for temperature, rotational speed and feeding sequence. Bilingual Chinese-English operation manuals were compiled to guarantee long-term stable execution of the optimized solutions.
· Small Batch Sampling Inspection: Four batches of pilot production were completed with full testing of aroma, system stability, raw material loss and low-temperature fluidity, all indicators passing inspection. The client’s R&D team confirmed the feasibility of the optimized solutions.
· Full Line Resumption: The client fully deployed the new formulas and operating standards, producing more than 20 consecutive batches without recurrence of the four core issues, restoring the product qualification rate to 100% and normal production capacity.
· End-user Feedback: Partner restaurants and offline retail outlets reported stable flavor and fragrance performance with favorable user experience, sustaining high end-market reputation.
