Notes:
Some of the viscoelastic properties of four peanut varieties were investigated by a series of uniaxial compression tests. The uniaxial tests were performed with a universal testing machine at temperatures of 5, 20 and 30°C, all at 55% relative humidity. Individual amino acid contents of the peanuts were determined by ion exchange chromatography. A proximate analysis was run to determine Kjeldahl nitrogen and oil. The results of the mechanical tests were analyzed to obtain uniaxial modulus of elasticity at various times and a decay constant. A correlation analysis of viscoelastic properties with chemical composition yielded significant correlations between modulus of elasticity and some individual amino acids, protein and oil. The amino aicds and protein were positively correlated while oil exhibited a negative correlation to the viscoelastic properties.
