批发芝麻油供应商 — 烤制、精制及冷榨

Sesame oil is sold commercially in three principal grades, each serving distinct applications with very different price and demand profiles.

Refined sesame oil is produced from sesame seeds using solvent extraction or mechanical pressing followed by RBD refining. The result is a light-coloured, mild-flavoured oil with a smoke point of approximately 210–230°C — suitable for frying, general cooking, and food manufacturing where sesame flavour is not the primary requirement. It is the lowest-priced sesame oil grade and is used in cosmetics, pharmaceutical manufacturing (it is an established carrier oil in injectable formulations), and as a base oil for blending in Asian food manufacturing.

Toasted (roasted) sesame oil is produced by cold-pressing or expeller pressing deeply roasted sesame seeds, then typically light-filtering without full refining to preserve the characteristic deep amber colour and intense nutty-roasted aroma. This is the most commercially recognised sesame oil in Asian cuisine — the Chinese, Korean, and Japanese condiment sesame oil that is drizzled over dishes after cooking rather than used as a frying medium. Its smoke point is lower (170–180°C) due to the presence of aromatic compounds from roasting, making it unsuitable for high-temperature cooking. Toasted sesame oil commands a significant price premium over refined grade and is primarily used in Asian sauces, dressings, noodles, dumplings, and marinades.

Cold-pressed sesame oil is produced without heat, pressing unroasted seeds to yield a pale golden oil with a mild sesame aroma. It retains higher levels of sesame lignans (sesamol, sesamolin) and vitamin E, and is positioned in health food and natural cosmetic markets. It is more expensive than refined but less intense in flavour than toasted.

For food manufacturing or retail buyers, confirm your required grade clearly — toasted and refined sesame oil look similar in descriptions but have completely different applications, flavour profiles, and price points.

The world's major sesame producing countries are India, Sudan, Tanzania, Ethiopia, Myanmar, and China. China dominates production and export of toasted sesame oil for the Asian food sector; India and Ethiopia are large exporters of refined sesame oil and sesame seed. The supply chain for toasted sesame oil is dominated by Chinese manufacturers supplying to East and Southeast Asian food markets globally.

Standard specifications for bulk refined sesame oil:

• Colour (Lovibond, 5.25" cell): <25Y, <2.5R for light-refined grades
• Free fatty acids (FFA as oleic): <0.1%
• Peroxide value (PV): <2.0 meq/kg
• Moisture and volatile matter: <0.1%
• Iodine value: 103–116
• Saponification value: 186–195

For toasted sesame oil, colour is typically assessed visually or by spectrophotometry — deep amber to red-brown is expected, and lighter colour may indicate under-roasting or dilution with refined oil. Request authenticity testing (sesamin, sesamolin, sesamol content by HPLC) if you are buying toasted sesame oil at scale for branded product use — adulteration with refined or blended base oil is a known fraud in the sesame oil category.

Critical allergen note: Sesame is a declared major food allergen in the EU (EU Regulation 1169/2011), UK, US (FASTER Act, effective 2023), and Canada. This has significant implications for food manufacturing — using sesame oil requires full allergen disclosure on finished product labels in these markets, and cross-contamination management in manufacturing facilities. This applies even to highly refined sesame oil from which most protein has been removed — regulatory bodies treat it as an allergen regardless. Confirm your regulatory obligations before incorporating sesame oil into a new product formulation.

Bulk formats: 180–200-litre drums, 1,000-litre IBC, 5kg–25kg pails. Sesame oil is liquid at ambient temperature. Flexi-tank supply is less common for sesame oil given the premium positioning and smaller trade volumes compared to commodity oils.
