True Story: Sri Lanka

“We are unable to control customer complaints due to moisture related complications, infestation, adulteration and most importantly providing certificates for sterilization requirements in different world regions. Also, the firm unable to cater into the lucrative spice retail packaging business both locally and internationally where percentage of markup will be at high 30s’ and 40s’.”


This post was publish on ethicallegend.com, one of my site somewhere in last month.[May|2021]. The feedback received from my viewers was fascinating there. Hence, I thought to share same with you too thinking that this might help you to develop your status quo to next level. 

1. What is black Pepper?

Black pepper (Piper nigrum) , well known as “king of Spice” is the most consumed spice throughout the world, taken from drupes of the plant. Most of the black pepper producing countries are comes under the “ developing country” category and processors/packers are in developed world asking more hygienic raw material from these countries. Even today it is hardly to prepare value added product such as consumer pack to SME exporters in developing countries. Main reason not to by value added product from developing countries exporters is microbial contamination occurred such as Salmonella.

2. Why sterilization?

Despite black pepper’s contribution to overall food sensorial properties, the main draw back not only for the black pepper but also some other spices are microbiological contamination. Reduction of microbial number in spices through various treatments become a necessity considering possible changes that could occur during spices’ storage and application in food resulting in public health risk. There are no avenues or methods to treat contaminants like E-coli and Salmonella if found in final products. Therefore, this has been a growing concern of USA and EU for the imports they make from developing countries where the sanitation is a luxury but a necessity.

3. How Contamination Occur?

The contamination may occur at any stage of processing such as harvesting, transportation and even during drying if the proper precaution measures are not taken. There are no avenues or methods to treat contaminants like E-coli and Salmonella which occur during the processing. This basically happen due to human interaction with pepper which can be eliminated but those methods are costly.

4. What are the Sterilization Methods Available?

Commonly used sterilization methods and description of the same are shown below.

Steam Sterilization
Gamma Irradiation
EtO (Ethylene Oxide)
Steam Sterilization

Steam sterilization is achieved by exposing the spices to be sterilized with saturated steam under pressure. Steam enhances the ability of heat to kill microorganisms of spices by reducing the time and temperature required to denature or coagulate proteins in the microorganisms. Color fading, reduce voltaic compound content and aroma deterioration is inevitable.

Gamma Irradiation

Gamma radiation is a type of high-energy radiation that is different from x-rays. The gamma irradiation process uses Cobalt 60 radiation to kill microorganisms on a variety of different products in a specially designed cell. This method associate some issues such as with high cost, safety measures skillful employees and finally mistrust of consumers.

EtO (Ethylene Oxide)

It is gas used mainly to sterilize medical instruments and treat spices. EtO exposure has been recorded to be associated with cancer of blood. This is not recommended by EU considering carcinogen residues but this method is accepted by USA.

All the above methods associate high cost for machinery & skillful employees which are impeding factors to adopt and use those methods for developing country processors/exporters.

5. Is there any alternative other than sterilization?

Yes. But it has to follow basic steps shown in below figure and this method is proven in Sri Lankan few exporters/processors and could be able to get through all required certifications and test reports requested by both EU & USA buyers.

Black pepper processing can be summarized as below along with necessary machineries in order to follow the process for anyone who who wishes to start pepper processing.
