Sesame Seeds
A Nutty Tale

Introduction

Sesame seeds, a small but versatile commodity, have been an integral part of global cuisine for centuries. While often overshadowed by larger agricultural exports, sesame seeds play a crucial role in various culinary traditions worldwide. In international commodity trading, sesame seeds are prized for their diverse applications, ranging from cooking oil to confectionery. In this blog, we'll explore the world of sesame seeds in international trade, focusing on the differences between non-hulled and hulled varieties, the various types of sesame seeds, and how they are graded.

Sesame Seeds: Hulled vs. Non-Hulled

One of the primary distinctions in the sesame seed market is between hulled and non-hulled seeds. Understanding this difference is essential for both buyers and sellers in the international trade of sesame seeds.

1. Hulled Sesame Seeds:
- Hulled sesame seeds have had their outer husks removed, resulting in a creamy-white appearance.
- They are often preferred in applications where a smoother texture and a milder flavor are desired, such as in bakery products and tahini production.
- Hulled sesame seeds generally command higher prices due to their increased processing.

2. Non-Hulled Sesame Seeds (Natural):
- Non-hulled, or natural, sesame seeds retain their outer husks, giving them a reddish-brown to black color.
- These seeds have a more robust and nuttier flavor, making them popular in traditional dishes and for garnishing bread and pastries.
- Natural sesame seeds are typically less expensive than hulled varieties because they require less processing.

Types of Sesame Seeds

Sesame seeds come in various types, each with its unique characteristics and applications:

1. White Sesame Seeds: These are one of the most commonly traded sesame seeds. They are available in both hulled and non-hulled forms and are versatile for various culinary uses.

2. Black Sesame Seeds: Often non-hulled, black sesame seeds are known for their rich, nutty flavor. They are used in desserts, savory dishes, and as a decorative element.

3. Brown Sesame Seeds: Brown sesame seeds can be either hulled or non-hulled. They offer a mild, slightly nutty flavor and are commonly used in bakery products and salads.

4. Red Sesame Seeds: These are less common but highly sought after for their unique reddish-brown color. They are typically non-hulled and used in Asian cuisine for their decorative appeal.

Sesame Seed Grading

Sesame seeds are graded based on several factors, including purity, color, and size. The grading process ensures consistency and quality in the international trade of sesame seeds. Here are some common grading types:

1. Purity: Sesame seeds are inspected for impurities such as stones, dirt, and other foreign matter. Premium-grade sesame seeds have the highest purity levels.

2. Color: The color of sesame seeds is crucial. Buyers often have specific color requirements based on their intended use.

3. Size: Sesame seeds are graded by size, with larger seeds typically commanding higher prices.

4. Moisture Content: Low moisture content is essential to prevent spoilage during storage and transportation.

5. Oil Content: The oil content of sesame seeds can vary, and it is an important consideration for buyers in industries like oil extraction.

The specific grading system can vary depending on regional and industry standards. Here are some common grades for sesame seeds:

1. Grade A: Grade A sesame seeds are of the highest quality. They are typically pure, free from impurities, and have a uniform color. These seeds are often used in premium food products and for high-quality oil extraction.

2. Grade B: Grade B sesame seeds are of good quality but may have some minor imperfections. They can still be used in various culinary applications and oil extraction.

3. Grade C: Grade C sesame seeds may have more noticeable imperfections, such as color variations or slight impurities. They are suitable for certain industrial uses, but not typically used in premium food products.

4. Standard Grade: Standard grade sesame seeds meet basic quality standards but may have a wider range of color variations and impurities. They are often used in more cost-sensitive food products and some industrial applications.

5. Natural or Whole Sesame Seeds: These are often graded based on color, with darker seeds considered of lower quality. They may also be categorized as natural, which means they have not been hulled, or mechanically hulled to remove the outer husk.

6. Mechanically Hulled Sesame Seeds: These are sesame seeds that have been mechanically processed to remove the outer husk. They are typically graded based on color, size, and purity.

7. Roasted Sesame Seeds: When sesame seeds are roasted, their color and flavor change. Roasted sesame seeds can also be graded based on factors like color consistency and flavor intensity.

8. Oil Content: some cases, sesame seeds may be graded based on their oil content. Higher oil content is often preferred in the oil extraction industry.

9. Specialty Grades: Depending on the region and specific industry requirements, there may be specialty grades for sesame seeds used in particular applications, such as baking or confectionery.

It's important to note that grading standards can vary from one country or region to another, and different buyers may have specific requirements based on their intended use for the sesame seeds. Buyers and sellers should be aware of the grading criteria that apply to their particular market and industry to ensure they meet quality and specification standards.
