Black pepper is produced from the still-green, unripe drupes of the pepper plant. Black pepper is the world's most traded spice and is one of the most common spices added to cuisines around the world. Its spiciness is due to the chemical piperine, not to be confused with the capsaicin characteristic of chili peppers. It is ubiquitous in the modern world as a seasoning and is often paired with salt. Packaging materials such as glass jar, laminated bags, steel jar, plastic jar, aluminum bag and poly bags are used for keeping black pepper powders.
