Alteration of The Content of Piperine and Essential Oil from Black Pepper and White Pepper After a Year Storage

Abstract Pepper is a type of spice plant in Indonesia that used for cooking spices. One of the advantages of this spice is that it has a spicy taste and distinctive scent caused by piperine and essential oils contained in pepper seeds. This research was carried out from June 2018 to October 2019, using the main raw material for the Natar 1 variety of pepper. The pepper seed was processed into black pepper and white pepper, and the yield was calculated. Then observed levels of piperine and essential oils of black pepper and white pepper prior to and a year after storage. The data obtained were processed in a qualitative descriptive manner. The results showed that after 12 months of storage, there was a decrease in piperine content of 9.91% and a decrease in essential oil content of 21.77%; while white pepper decreased piperine content by 19.45% and essential oil content decreased by 56.91%. Based on the results of this study, good storage technology is needed to support the sustainability of the availability of black pepper and white pepper in particular, as well as pepper farming in general.
