- Abstract
- This study was conducted in order to investigate the effect of different drying methods on free amino acids and dipeptide contents, Warner-Bratzler shear force and sensory property of beef jerky products. The drying methods used for this study were sun-drying, shade-drying and hot air-drying methods. The sun-dried beef jerky had the highest free amino acids (277.45 mg/100 g) followed by shade-dried (206.43 mg/100 g) and hot air-dried (111.88 mg/100 g) ones, whereas the amount of dipeptides were the highest in the shade-dried beef jerky followed by sun-dried and hot air-dried ones. The fatty acid composition of the beef jerky was not shown any difference among the beef jerkies with 3 different drying methods. The color L*-value of the beef jerky was lower in the hot-air dried, while the a*-value was higher in the sun-dried one. The shade-dried jerky showed a lower b*-value. The shear force of beef jerky was lower when it was either sun-dried or shade-dried than when it was hot air-dried. Sensory evaluation revealed that hot air-dried beef jerky scored lower than the sun-dried and shade-dried ones (p<0.05). Therefore, using either the sun drying or shade drying methods is more desirable than using the hot air drying method when manufacturing beef jerky for superior physicochemical qualities.
