Sesame Seeds

What are moisture factors in sesame seed export?

Moisture content is one of the most critical quality parameters influencing the global trade of sesame seeds. Improper moisture levels during harvesting, processing, and storage can significantly compromise the physical, chemical, and microbial integrity of the seeds, leading to far-reaching consequences in international markets.

MOISTURE STANDARDS IN SESAME SEED EXPORT

1. Fungal Contamination and Aflatoxin Risk

High moisture content, typically above 8–9%, creates favorable conditions for fungal growth. Contamination by aflatoxins is a major concern in key export destinations where regulatory limits are strict. Shipments found to exceed permissible aflatoxin levels are often rejected, confiscated, or destroyed, leading to significant financial and reputational loss.

2. Loss of Physical and Nutritional Quality

Excessive moisture accelerates the degradation of seed structure. It can lead to:

Discoloration and loss of visual appeal.
Premature germination or sprouting during transit.
A decline in oil content and flavor profile.
Increased incidence of broken or split seeds during handling.

These quality defects reduce the market value of the product and can result in downgrading or outright rejection by buyers and regulatory authorities.

3. Reduced Shelf Life and Storage Stability

Sesame seeds with high moisture content exhibit decreased storage stability. Moisture encourages microbial activity and chemical reactions that cause rancidity, especially in the high-fat content present in sesame seeds.

Under humid storage conditions or in inadequately ventilated containers, condensation may occur, further exacerbating microbial growth. This compromises the product’s shelf life and makes it unsuitable for long-term distribution or processing into derivative products such as sesame oil, tahini, or confectionery.

4. Regulatory Compliance and International Standards

Most importing countries enforce maximum allowable moisture content in sesame seeds, often ranging between 6% and 8%, depending on the market. Exporters failing to meet these standards may face:

Shipment rejections or returns.
Loss of trade licenses or blacklisting by buyers.
Increased scrutiny and mandatory pre-shipment inspections.
Additional costs for treatment, drying, or re-exporting.

Maintaining optimal moisture levels is not just a quality control issue—it is a regulatory requirement tied to access and credibility in international markets.

5. Economic and Logistical Impacts

The financial risks associated with high-moisture sesame seeds extend beyond quality losses. These may include:

Costs associated with re-drying, fumigation, or re-packaging.
Increased freight charges due to added weight from moisture.
Delays in shipping schedules and customs clearance.
Compensation claims or penalties from international buyers.

Long-term damage may also occur in the form of reduced buyer confidence and loss of export contracts.

Moisture Content and Standards in Export of Sesame Seeds

Moisture content is a key quality factor in the export of sesame seeds. Excessive moisture increases the risk of mold, aflatoxin contamination, spoilage, and shipment rejection. Sesame seeds need to be stored and dried correctly to preserve their export quality.

Maximum allowable moisture content: usually 6% – 8%
Premium export quality: often maintained at below 6%
Above 8% moisture: considered risky, as it encourages fungal growth and discolouration and reduces shelf life

Global Standards: Typically between 6% and 8%
European Union: ≤ 7%–8%
Japan & North America: ≤ 6%–7%
Middle East: Up to 8% accepted
India (Export Guidelines): ≤ 6%, as per APEDA and FSSAI

Why use desiccant bags in sesame seed export?

Maintaining the quality of sesame seeds during international shipment requires effective moisture control. Cargo desiccant bags serve as a preventive solution by absorbing excess humidity inside containers, ensuring that the product reaches its destination without spoilage, mold, or regulatory issues. These bags are especially vital during long transit periods or routes with high humidity fluctuations.

1

Prevention of Mold and Fungal Growth Sesame seeds are highly sensitive to moisture, particularly during maritime transport. When humidity levels rise, conditions become ideal for mold development. Cargo desiccant bags reduce moisture levels in the air, preventing fungal activity and maintaining a clean, contamination-free environment throughout the shipment.
2

Reduction in Aflatoxin Risk Aflatoxins are poisonous substances that some fungus make, usually in warm, humid environments. These contaminants are a major concern in food exports, as they are closely monitored by international regulatory bodies. By minimizing moisture, cargo desiccant bags help prevent the formation of aflatoxins, thereby supporting food safety compliance and reducing the likelihood of shipment rejection.
3

Protection Against Container Rain (Condensation) Temperature variations during sea transport can lead to condensation inside shipping containers, commonly referred to as “container rain.” This occurs when warm, moist air condenses on cooler container walls and ceilings, forming droplets that fall onto the cargo. Cargo desiccant bags capture ambient moisture before condensation can occur, significantly lowering the risk of seed damage from dripping water.
4

Preservation of Sesame Seed Quality and Physical Appearance Moisture exposure can cause sesame seeds to clump, discolor, lose aroma, and develop off-flavors. It may also affect oil content and reduce the seeds' market value. Cargo Desiccant bags play a crucial role in preserving visual and sensory characteristics by maintaining a dry shipping environment, ensuring that seeds arrive in pristine, export-grade condition.
5

Extension of Shelf Life Effective humidity control during shipment plays a crucial role in preserving the chemical and physical stability of sesame seeds. By maintaining low moisture conditions, cargo desiccant bags help prevent oxidation, inhibit microbial growth, and minimize other spoilage factors. This protection contributes to an extended shelf life, allowing for longer storage durations and smoother distribution at the destination.
6

Minimization of Economic Losses During sesame seed exports, moisture-related issues such as contamination, cargo rejection, or repacking can result in significant financial losses. Cargo desiccant bags offer a cost-effective method of risk mitigation, helping to avoid delays, penalties, and reputational damage. Uses of cargo desiccant bag reduces the need for reprocessing, disposal, or compensation claims from buyers.
7

Support for Compliance with International Quality Standards Many importing countries enforce strict guidelines on moisture content and fungal contamination in food products. The use of desiccant bags contributes to meeting these standards by maintaining optimal conditions during shipment. This strengthens quality assurance and helps ensure smoother customs clearance and acceptance upon arrival.
