Abstract

This study aims to analyze the changes in the physical properties of peanut seeds (Arachis hypogaea L.) during storage in a humid environment. Several parameters observed include dimensions, volume, surface area, bulk density, true density, porosity, and angle of repose. Measurements were taken at three different moisture contents, namely 6.24%, 10.28%, and 14.11%. The results show that increasing moisture content significantly affects the physical properties of peanut seeds. The arithmetic diameter increased from 10.11 mm at moisture content 1 to 12.21 mm at moisture content 3, while the geometric diameter increased from 9.58 mm to 11.63 mm. Both arithmetic and geometric volumes also increased, from 540.42 mm³ to 953.79 mm³, and from 460.16 mm³ to 823.39 mm³, respectively. Increasing moisture content also influenced both bulk density and true density, with true density ranging from 2,990 g/cm³ to 2,444 g/cm³, while bulk density decreased from 2.002 g/cm³ to 1.656 g/cm³. Furthermore, the angle of repose of the peanut seeds increased from 21.7° to 31.3°, indicating an increase in cohesion between the seed particles due to the presence of water. This study indicates that moisture content plays a crucial role in determining the physical properties and storage stability of peanuts, which could potentially affect product quality and shelf life during long-term storage. Keywords: Peanuts, moisture content, physical properties, storage, humid environment.
