Sesame Seed

Sesame seed is the spice produced from the oilseeds of Sesamum indicum, an annual herb in the Pedaliaceae family.

REGION OF ORIGIN

The wild relatives of the Sesamum indicum evolved on the ancient savanna plains of sub-Saharan Africa. They still grow abundantly in Ethiopia today. Through trade, they eventually made it to India, where they were first domesticated into the Sesamum indicum species.

PART & COLOR

Depending on the variety and how they're processed, the small, drop-shaped seeds can come in a variety of colors. The most common are pale and creamy white, but they can also be yellow, red, brown, or black (below). The outer husk of the seed is often removed during processing, leaving the “hulled” white seeds that are so popular for cooking.

HARVEST

Sesame is planted in the late spring. After 4-6 weeks, it starts flowering and the seed pods form. They are ready for harvest in the early autumn when they turn yellowish brown, but they must be cut before they fully ripen to stop them from spitting open and scattering the seeds. They are then dried so the seeds can be extracted in a controlled environment.

FLAVOR & AROMA PROFILE

Sesame seeds have a soft, nutty aroma. It’s akin to toasted almonds or hazelnuts with subtle earthy notes underneath. They taste mildly nutty and buttery.

Toasting sesame seeds gives them much more depth. It makes them nuttier and brings out a rich, smoky, savory quality. They also offer a light crunch, a welcome textural contrast to your other ingredients.

Tahini is another popular way to experience this spice, ever since ancient Mesopotamia. It’s a smooth paste made only by grinding toasted sesame seeds. Its creamy consistency heightens the perception of sesame seeds' rich nuttiness and light bitterness.

CULINARY USES

The versatility of sesame seeds is on display in Asian cuisine. They’re sprinkled over sushi, meats, noodles, and rice. In Japan, they're an essential element of two of the most popular seasoning blends: furikake and shichimi togarashi.

Sesame oil, derived from the seeds, is a critical ingredient in China, Japan, Korea, and Southeast Asia. It’s often added to sauces and dressings or used as a finishing oil for stir-fries.

In Middle Eastern cuisine, sesame mainly takes on its tahini form, which is critical to hummus, baba ghanoush, and halva. Sesame seeds also weave their way through European breads, pastries, and salads. You also can’t deny their efficacy on the bun of an American burger.

Important Considerations

Most Research is Preliminary: While research is promising, more extensive human clinical trials are needed to definitively confirm the efficacy and safety of sesame seed's medicinal properties.
Dosage Matters: Researchers commonly use concentrated extracts, so standard dietary consumption may not yield the same results. More studies are required to establish proper dosages and administration methods.
Medication Interaction: Sesame seed should not be considered a replacement for conventional medical treatments. While it is generally safe for most people, it is critical to exercise moderation and consider interactions with other medications.
Disclaimer: Consult healthcare professionals before using spices or herbs medicinally.

CHEMICAL COMPOSITION

The unique combination of fatty acids and lignans in sesame seeds is most responsible for their beloved culinary characteristics. Here is a breakdown of the key compounds present in sesame seeds, highlighting the bioactive and sensory effects of each:

Flavor & Aroma Compounds

2-Pentylfuran
- Culinary: Contributes to the green, earthy aroma of sesame, particularly when seeds are roasted or in the form of sesame oil.
- Medicinal: Potential antioxidant activity.
Other Volatile Compounds
- Sesame seeds contain various other volatile compounds, including aldehydes, ketones, pyrazines, and furans, which contribute subtle nuances to their flavor.

Other Phytochemicals

Lignans (sesamin, sesamol, sesaminol, episesamin)
- Culinary: The high concentration of these unique lignans in sesame seeds contributes to their nutty, subtly sweet aroma and slightly bitter undertones. Their effects are most pronounced in toasted sesame oil, but they also enhance the seeds' savory profile when they’re in the form of tahini (sesame paste).
- Medicinal: Potent antioxidant and anti-inflammatory properties. Lignans in sesame seeds have also been linked to improved cholesterol levels, blood pressure regulation, and potential anti-cancer effects.
Phytosterols
- These plant compounds structurally resemble cholesterol and may help lower blood cholesterol levels by competing with cholesterol for absorption in the gut.
Phenolic Acids (ferulic acid, p-coumaric acid)
- Culinary: These phenolic acids contribute to the antioxidant properties of sesame seeds and may influence the flavor profile by adding a slight bitterness.
- Medicinal: Potent antioxidant and anti-inflammatory activity.

Fatty Acids

Linoleic Acid (omega-6 fatty acid)
- Culinary: The most abundant fatty acid—imparts a rich, nutty flavor with subtle earthy undertones.
- Medicinal: Essential for healthy skin and hair.
Oleic Acid (omega-9 fatty acid)
- Culinary: Adds a smooth, buttery note to the overall flavor profile.
- Medicinal: Potential heart-health benefits.

Understanding Composition

Since the macronutrients (fats, carbohydrates, proteins) and micronutrients (vitamins, minerals) are listed in the Nutrition Facts above, this section focuses on the compounds most responsible for a spice or herb's culinary and medicinal properties.
Chemical composition can vary widely, mainly in the concentrations of compounds. This is why there are differences in quality and why spices are often graded by measuring the key compounds that directly influence flavor, aroma, and color.
This variation, and therefore, quality, is affected by variety/cultivar, age/ripeness/freshness, region, terroir, environmental stressors, potential adulteration, and the techniques deployed throughout the following processes: cultivation, harvesting, processing (drying, curing), shipping, storage, and preparation (grinding, grating, infusing, toasting). A magnificent spice is a celebration of a complex journey, shaped by both natural forces and human ingenuity.

ALTERNATIVE USES

Here are some of sesame seed's popular alternative uses:

Cultural and Spiritual Significance
- In India and other parts of Asia, sesame seeds are associated with abundance, prosperity, and good luck and are often used in religious ceremonies and rituals.
Skincare
- Sesame seed oil is added to lotions, creams, and soaps to protect, soothe, and hydrate skin.
Hair Care
- Sesame oil is believed to nourish and strengthen hair in Ayurveda and other traditional medicine systems.
Oil Pulling
- Sesame oil is often used in oil pulling, the ancient Ayurvedic technique of swishing oil in the mouth to support oral hygiene and general health.
Biofuel
- Sesame oil is starting to get noticed as a possible ingredient for making biodiesel, a cleaner alternative to traditional fuel. Its high fat content makes it a great option for a process called transesterification, which turns the oil into the key components of biodiesel. This process basically transforms sesame oil into a fuel that can power engines while being more eco-friendly.
Nanotechnology
- Sesame seed oil can create stable emulsions, which means it can effectively mix oil and water without rapid separation. This is being investigated for use in nanotechnology, including the creation of nanomaterials and medication delivery systems.
Other Industrial Uses
- Due to its high viscosity and resilience at high temperatures, sesame oil is used in a wide range of industrial applications, such as paints, hydraulic fluids, and machinery lubricants.

Disclaimer

While sesame seed shows promise in these areas, its effectiveness may be limited compared to commercial alternatives.

SUBSTITUTIONS

When sesame seeds are unavailable or you're looking to add a different dimension to your dish, several substitutes can step in to offer similarities:

Poppy Seeds
- These tiny seeds provide a similar delicate crunch to sesame seeds, but their flavor is more subtle and slightly sweet. They are often used in baked goods and sprinkled on top of dishes for visual appeal and texture.
Hemp Seeds
- These seeds have a slightly earthy and nutty flavor, although less pronounced than sesame seeds. They offer additional nutritional benefits, being rich in protein and omega-3 fatty acids.
Sunflower Seeds
- These seeds have a milder nutty flavor and a slightly softer texture than sesame seeds. They can be toasted for a more pronounced flavor and used as a 1:1 substitute in most recipes.
Pumpkin Seeds
- With a slightly sweet and nutty flavor, pumpkin seeds can add a similar richness to dishes. Toast them lightly to enhance their flavor and use them in salads, granola, or baked goods.
Tahini
- A paste made from ground sesame seeds, tahini offers the most direct flavor substitute, but it's not a good substitute in terms of texture. Use it in dressings, dips, or sauces to capture the nutty essence of sesame seeds.

Substitution Tips

Incomplete Substitution: All spices and herbs are too complex to match exactly, so focus on which aspects of their flavor, aroma, texture, or color you wish to replicate.
Quantity: Start with a small amount of the substitute and adjust to taste. It won't be a 1:1 exchange in flavor or potency.
Context: Consider the entire dish and how the substitute's full flavor profile will merge with the other ingredients.
Experimentation: Playing with substitutions is a great opportunity to explore how different flavors interact. If you approach it with curiosity, you may really enjoy the process and make some delicious discoveries along the way.

A BRIEF HISTORY

The wild relatives of the sesame plant are native to the ancient plains of sub-Saharan Africa, where they still grow abundantly today. Through trade, they traveled through North Africa and the Middle East and eventually arrived in India. This is where the domesticated species, Sesamum indicum, was likely first cultivated thousands of years ago. Ancient Hindu scriptures like the Vedas talk about how sesame seeds (or til) were served as offerings to the gods. They were included in funeral rights to ensure the immortality of the soul. Til was a symbol of the eternal existence of life.

From India, sesame seeds and their precious oil spread to East Asia, the Middle East, and back to Africa. When sesame seeds were introduced to China from India via the Silk Road, sesame oil in particular became incredibly important to their cuisine, and was considered a luxury. In the Middle East, the plant’s ability to grow even with poor soil and little to no rainfall made it a vital crop. The Assyrians and Babylonians were among the first to cultivate sesame extensively. They were likely the first peoples to create tahini, the sesame paste that is still a staple of Middle Eastern cuisine to this day. Believing the gods drank sesame wine before creating the earth, the Babylonians called it the "seed of the gods." In Africa, sesame seeds were a crucial part of the overland Saharan trade routes, and sesame oil was exchanged for gold, ivory, and other valuables.

In ancient Egypt, sesame oil was used in cooking, medicine, and cosmetics. The Ebers Papyrus, one of humanity’s oldest medical texts, mentions sesame oil as a remedy for many health issues. The Egyptians also used sesame seeds in bread and other foods, perhaps being the first to realize their stellar nutritional value. Roman soldiers took it one step further, eating a mixture of honey and sesame seeds for energy before battle. This is perhaps the first "energy bar."

In the 9th century, the phrase “open sesame” emerged from the tale of Ali Baba and the Forty Thieves in the famous collection of Middle Eastern folktales, One Thousand and One Nights (also known as the Arabian Nights). This phrase, still popular around the world today, refers to the way sesame pods burst open when they reach full maturity, which must have seemed fantastical to early harvesters.

The global popularity of sesame seeds grew in the 20th century as international cuisines became more accessible. Sesame oil became a common ingredient in Asian cooking worldwide, and tahini became a staple for the health-conscious. The rise of vegetarian and vegan diets further boosted sesame’s popularity due to its high content of healthy fats.

Today, sesame seeds are grown in over 60 countries, with major production centers in India, China, Sudan, Myanmar, and Nigeria. They are a key addition to many foods, from baked goods to sushi and salad dressings. Beyond the kitchen, sesame oil is still used in traditional medicine, skincare products, and even as a biofuel. It has great versatility, and we'll likely see its uses expand in the years to come.
