Sesame Seed
A premium, flavor-defined oilseed
Sesame stands apart from bulk oilseeds: it carries a very high oil content (roughly 48–55%) but its value rests overwhelmingly on flavor and tradition, not on commodity oil economics. The market splits into two distinct products. Toasted (roasted) sesame oil is deep-roasted to a dark color and intense aroma, used as a finishing condiment across East Asian cuisines and priced accordingly. Light or cold-pressed sesame oil is gently processed for a mild, pale oil used in cooking and some traditional and cosmetic applications. The two are effectively different products from the same seed, separated entirely by how much heat the seed sees before pressing.
Processing route: roast level is everything
Sesame is small and thin-coated, so it is generally pressed whole; some light-oil and tahini production dehulls for a paler product, but oil pressing usually does not. The decisive processing variable is roasting: deep roasting builds the color and aroma of toasted sesame oil, while minimal or no roasting preserves the light style. Traditional producers prize control here — flat-bottom (wok-style) roasters and careful temperature management define the flavor, and over-roasting that scorches the seed ruins a high-value batch. Gentle pressing, often hydraulic or slow screw, suits the premium, small-batch nature of the product, keeping the oil cool where the light style demands it.
Market position and why scale is small
Because sesame oil is a flavor and finishing product rather than a bulk frying oil, its processing is inherently small-batch and quality-obsessed. The premium is real but the volumes are modest, and the whole operation optimizes for consistency of roast and cleanliness of flavor rather than throughput or lowest residual oil. For a mill, sesame is an opportunity to build a differentiated, high-margin product line — provided it can source good seed, control roasting precisely, and press gently. It rewards craft far more than it rewards scale.
Typical processing route
Cleaning → Roasting (level = product) → Pressing → Filtering → Filling

FAQ
How much oil is in sesame seed?
Sesame is very oil-rich — roughly 48–55% — but its value comes from flavor, not commodity oil economics.
What is the difference between toasted and cold-pressed sesame oil?
Roast level. Toasted sesame oil is deep-roasted for a dark, aromatic finishing oil; light/cold-pressed sesame oil is minimally heated for a pale, mild oil. Same seed, different products.
Is sesame pressed whole or dehulled?
Oil sesame is usually pressed whole. Dehulling is used for lighter oil and for tahini, giving a paler product, but is not standard for pressing oil.
Is sesame good for a small premium mill?
Yes — high oil content, a strong flavor premium and small-batch character make it ideal for a craft, high-margin line, provided roasting is controlled precisely.
