Sesame Seed

Natural sesame retains the seed coat and is bought where the coat is wanted — bakery toppings and some oil pressing — or where the buyer intends to hull it. Hulled sesame has had the coat removed, which changes colour and mouthfeel and makes the seed the pale, uniform article used in tahini and confectionery. Hulling exposes the seed and shortens its keeping quality, so hulled lots are handled and stored more carefully than natural ones.

Colour is a trading category rather than a cosmetic detail. White, brown, and black sesame are distinct articles with distinct uses and origins, and buyers specify colour uniformity because a scatter of off-colour seeds is visible in the finished product. Black sesame in particular serves markets where its appearance is the point.

The bulk of traded sesame goes to food manufacture, where it is used whole, hulled, roasted, or ground. A substantial share is pressed for oil, but the pressing is often oriented toward flavour rather than commodity oil supply: roasted sesame oil is a seasoning product whose value lies precisely in the character that full refining would remove. Cake from pressing is used in animal feed, though the volumes are modest relative to the major oilseed meals.

• Food — tahini, halva, and other paste and confectionery products
• Food — bakery toppings, snacks, and whole-seed culinary use
• Oil — pressed oils, including roasted seasoning oils and lighter culinary oils
• Feed — cake from pressing, a secondary outlet

AgricultureID models no sesame oil or sesame cake product entry at present; those pathways are real but are not yet published as separate entries, and are described here rather than linked.

Beyond purity and colour, lots are described by moisture, free fatty acid content, admixture and foreign material, and damaged or immature seed. Sesame’s small size and the way it is harvested make foreign material a persistent issue — soil, stones, chaff, and other seeds — which is why cleaning and sorting are central operations rather than finishing touches.

Sesame has a documented history of microbiological contamination incidents in international trade, and several jurisdictions have applied import controls and certification requirements to sesame consignments as a result. The relevant point for this entry is structural: because sesame is frequently consumed with little or no heat step, the seed’s own condition carries the risk rather than a later kill step. Which controls apply, what testing is required, and what limits are in force are determined by the food-safety authority in the destination market and change over time.

Sesame is oil-rich and small-seeded: it packs tightly, resists aeration, and its oil goes rancid if the seed heats. Hulled seed, having lost its coat, deteriorates faster than natural seed and is more prone to picking up moisture. Lots are kept dry, cool, and clean, with insect protection, and are typically moved in bags or containerised rather than in the large bulk vessels used for the major oilseeds — a reflection of both trade scale and the food-grade handling the commodity demands.
