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

摘要

I paid attention to how mustard seeds interact with storage container for a period of 6 months. I examined some of the physical properties of these seeds such as: length L (mm), width W (mm), thickness T (mm), geometric mean diameter Dg (mm), sphericity Φ (%), porosity ε (%), volume V (mm 3 ), mass m (g), bulk density ρ b (g/cm 3 ), true density ρ tr (g/cm 3 ) before and after storage for six months at normal temperature and pressure. The samples were: sample 1 mustard seeds in a plastic bag and sample 2 mustard seeds in a plastic box with a top. The physical dimensions of the samples measured in three mutually perpendicular directions before storage had values between: for T minimum – 1.90 mm, maximum 2.61 mm, for W – minimum 1.87 mm, maximum 2.44 mm, for L – minimum 1.82 mm, maximum 2.58 mm. After the six months of storage at normal temperature and pressure in various packages, the physical dimensions of the mustard seeds varied the least for the seeds in sample 1.
