lycium-barbarum-concrete from Top is the concentrated aqueous/alcoholic extract of Lycium barbarum (goji berry) — a sweet-red, nutrient-dense fruit concrete, not a distilled oil. Top declares the botanical name on every COA.Origin is Ningxia / Gansu / Qinghai cultivated bases, China. Goji is a medicine-food dual-use species listed by China's NHC; goji products are ordinary food raw materials in China. Top keeps the species + origin declaration so the identity is traceable. Because it is a fruit extract (not a distilled oil), it is labelled and used as a fruit concrete / extract, not an essential oil; nutrients come from polysaccharides...

Top can supply pre-blended (defined ratio in a food-grade carrier) or pre-diluted forms for easier handling and lower-cost trials. Blend base and concentration are agreed per order and stated on the COA.Note that blending changes the measured specification window, so the COA always declares the actual concentration and base. Neat lots remain the default for buyers who formulate in-house.

Top controls consistency through Q/XXXX and per-batch QC matched to the reference profile. Traceability runs raw-material source through processing to the finished product with a lot-specific ledger and retention sample.If your application needs tight tolerances, tell Top and we can select lots from the same source or blend to a target profile. Every shipment carries a lot number linking to the COA and assay on file.

AppearanceA dark-red to reddish-brown viscous concrete/paste. Odour/TasteCharacteristic sweet, slightly earthy goji berry odour.Because it is a natural aromatic material, the aroma is the natural Lycium barbarum L. (goji berry) character. Sensory evaluation follows an in-house panel; Top provides the odour/flavour description on the COA and can supply a reference sample.Store sealed, away from light/heat/moisture.

Top provides ongoing support: lot traceability and re-test within shelf life using the retention sample, documentation re-issue (COA / SDS / origin / health / phytosanitary cert copies), formulation advice and a responsive complaint channel. For LTA buyers we assign a dedicated contact and periodic review of grade consistency.We treat the relationship as long-term — the after-sales step is where we protect your production continuity, not an afterthought.

Top authenticates by:HPLC for polysaccharides and carotenoids, GC for the fruity volatile fingerprint matched to the natural Lycium barbarum L. (goji berry) profile and the GC/MS fingerprintGC/MS fingerprint plus targeted adulterant screeningSpecies + "Lycium barbarum L. (goji berry) species-specific raw material" declaration on COAHeavy metals + microbiology per food-safety.Every lot ships with COA plus assay. We screen adulterants, heavy metals and solvent residue.Lots failing the natural profile or exceeding limits are blocked.
