Case Study: Garlic Oil Sample Test to Long-Term Bulk Supply Partnership
Overview
A Europe-based flavor formulation company specializes in savory food flavors and seasoning blends. They were sourcing natural garlic oil for their snack and savory seasoning lines, but struggled to find a supplier with stable allicin content, consistent aroma, and reliable batch-to-batch uniformity.
After contacting our team at Dielegance Biotechnology, they started with sample evaluation, followed by lab testing, trial bulk shipment, and finally built a long-term supply partnership. They also extended cooperation to our other botanical raw materials later.
Stage 1: Sample Request & Initial Evaluation
The client reached out with clear specification requirements: 100% natural steam-distilled garlic oil, stable flavor profile, qualified heavy metal, pesticide residue and microbiology indicators, suitable for savory flavor compounding. We prepared free samples with full supporting documents: COA, specification sheet, GC report and storage guidance, then arranged international delivery for their R&D team.
During the initial sensory test, their formulators checked the garlic aroma intensity, purity and off-notes. The sample matched their target flavor direction and moved forward to formal lab analysis.
Stage 2: Lab Testing & Confirmation
The client’s in-house laboratory ran a full set of tests on our garlic oil sample:
Sensory assessment: color, odor, flavor
Chemical index: allicin content
Safety indicators: heavy metals, pesticide residues, PAHs, microbiological test All test results met their internal standards. Their R&D team confirmed that our garlic oil blended well with other flavor components without unwanted bitter or burnt notes. After successful sample validation, they decided to place a trial order
Stage 3: 500kg Trial Bulk Order
The client placed a 500kg trial order for natural garlic oil. Before production, we shared the production schedule and pre-production test data. After finishing production, we retested the finished batch and sent the updated COA for confirmation before shipment. We followed proper packaging and cold-friendly shipping suggestions to protect the oil from oxidation during transit. When the goods arrived, the client did incoming inspection. The batch index and aroma were consistent with the approved sample. The trial run in their seasoning production line went smoothly.
Satisfied with our product quality, technical support and after-sales service, the client turned the trial purchase into recurring bulk orders of garlic oil.
As trust grew, they started exploring more raw materials from our catalog. They later added ginger oil and other botanical extracts into their purchasing list for new product development.
Now we regularly communicate on new formulation needs, adjust specifications when required, and support their new flavor project development.
Key Takeaways From This Cooperation
1) Consistent sample-batch consistency is critical for flavor manufacturers.
2) Complete test documentation helps R&D teams save evaluation time.
3) Flexible sampling service lowers the risk for customers’ new formula development.
4) Reliable logistics and professional technical communication support long-term partnership.
If your team is looking for dependable natural garlic oil or botanical extracts for flavor, cosmetic or functional food formulations, we welcome you to start with sample testing. Our R&D and QC team can provide technical support throughout your formulation process.
