从China供应商批发进口Algae Docosahexaenoic Acid Oil Cas No. 6217-54-5 — FOB条款

Algae Docosahexaenoic Acid Oil (CAS 6217-54-5) from Deyang Rishon Biochem Co., Ltd. is a pale yellow to light brown liquid at 25°C, characterised by an algal characteristic flavour without off-odours. The oil is docosahexaenoic acid (DHA) derived from microalgae fermentation, offering a vegetarian and potentially more sustainable alternative to fish-source omega-3 oils. It dissolves in organic solvents including ethanol and light petroleum, but is immiscible with water, standard for long-chain polyunsaturated fatty acid (LC-PUFA) oils. The product is packaged in 5 kg net aluminium bottles purged with nitrogen to minimise oxidative degradation. This material serves nutraceutical, functional food, infant formula, and dietary supplement manufacturers seeking algae-origin DHA with defined purity profiles.

The oil's fatty acid profile is centred on DHA (C22:6 n-3), typically comprising 35-55% of total fatty acids in standard algae DHA oils, though the exact concentration for this grade is not stated. Remaining fractions include other omega-3s, saturated fatty acids (palmitic, stearic), and minor monounsaturates. Peroxide value, anisidine value, and total oxidation (TOTOX) are critical quality parameters for LC-PUFA oils, with typical industry limits of 5 meq O2/kg, 20, and 26 respectively for premium grades. The nitrogen purge in packaging is essential because DHA's six double bonds render it highly susceptible to autoxidation, leading rancidity, colour darkening, and formation of fishy-volatile aldehydes. Antioxidant addition, often mixed tocopherols or ascorbyl palmitate at 500-2000 ppm, is standard practice; confirm whether Deyang Rishon includes these or supplies the oil unprotected.

Primary buyers include infant formula producers (where algae DHA avoids marine allergen labelling), vegan supplement brands, and functional food developers targeting pregnancy, cognitive health, and eye health markets. The oil may also serve pharmaceutical applications requiring purified DHA for lipid emulsions or API synthesis. Importers should request the certificate of analysis for each lot, including fatty acid methyl ester (FAME) profile by GC, moisture and volatile matter, and heavy metals (lead, arsenic, mercury, cadmium). Stability data under accelerated conditions (40°C/75% RH) and cold chain recommendations for bulk storage should be confirmed. Regulatory acceptance varies: algae DHA is GRAS in the USA for infant formula and has Novel Food status in the EU; buyers must verify Deyang Rishon's documentation supports their specific market approval pathway.

Deyang Rishon Biochem Co., Ltd. is headquartered at No. 172 North Tianshan Road, Deyang, Sichuan Province, China, postal code 618000. Deyang is an industrial city in western China with established chemical and biochemical manufacturing infrastructure, including access to the Chengdu economic corridor. The supplier holds a Harbor trust tier on the platform, but shows a 0.00% response rate with zero average response hours, indicating no engagement through platform-mediated messaging. Buyers should plan for direct outreach, potentially via telephone or WeChat, or engage a Sichuan-based sourcing agent to facilitate communication.

The company profile for this listing is limited to a single product, Algae Docosahexaenoic Acid Oil, with no stated additional product portfolio, manufacturing scale, or year of establishment. No certifications such as ISO 22000, HACCP, GMP, or organic credentials are mentioned in the source data. The absence of company history, employee count, revenue figures, or client references means all claims about scale or market position must be verified independently. Importers should request a company brochure, manufacturing licence, and audit reports if considering Deyang Rishon as a primary supplier for regulated applications such as infant formula or pharmaceutical excipients.
