Saffron packaging: main factors to be considered

Saffron is one of the most widely used and expensive spices. Maintaining the quality of this product and increasing its shelf life during the distribution and consumption cycle is mandatory. Different packages have been designed for saffron which differs in material, design, manufacturing method, and quality. In this study, first, the types of common packaging for saffron and their characteristics were investigated. The role of nanotechnology and biomaterials in improving the properties of saffron packaging was also discussed. In the following, some important properties of saffron packaging were discussed. Finally, other methods of saffron storing and new recommendations for producing intelligent or active packaging were presented. Based on the results of this research, few studies reported the development of saffron packaging considering the growth of microorganisms, oxidation, and barrier properties. The lack of using different nanoparticles and biodegradable biomaterials was not considered in the studies notably. However, saffron packaging can be significantly developed by mimicking the smart and active packaging systems.

Automated summary

This study investigated the common packaging types and characteristics of saffron, and discussed the role of nanotechnology and biomaterials in improving packaging properties. Few studies have considered the development of saffron packaging in terms of microbial growth, oxidation, and barrier properties, and the use of different nanoparticles and biodegradable biomaterials has not been explored. However, by mimicking smart and active packaging systems, saffron packaging can be significantly improved.
