PHYSICAL PROPERTIES OF CORIANDER SEEDS AND HOW THEY ARE INFLUENCED BY PACKAGING

Mihaela Jarcău

Abstract
I paid attention to how coriander seeds interact with storage container for a period of 6 months. I examined some of the physical properties of the seeds such as: length L (mm), width W (mm), thickness T (mm), geometric mean diameter Dg (mm), sphericity Φ (%), porosity ε (%), volume V (mm3), mass m (g), bulk density ρb (g/cm3), true density ρtr (g/cm3) before and after storage for six months at normal temperature and pressure. The samples were: sample 1 coriander seeds in a plastic box with a top, sample 2 coriander seeds in a plastic bag. The physical dimensions of the samples measured in three mutually perpendicular directions before storage had values between: for T minimum - 3.39 mm, maximum 4.12 mm, for W - minimum 3.37 mm, maximum 3.80 mm, for L - minimum 4.14 mm, maximum 4.84 mm. After the six months of storage at normal temperature and pressure in various packages, the dimensions of the coriander seeds suffer different modifications that depend on the nature of the package used for each sample.
