Effect of Vacuum Packaging on Storage Quality of Peanut

The purpose of the study is to investigate the effect of vacuum packaging on storage quality of peanut. The acid value, peroxide value, relative conductivity, mildew rate and germination rate of peanut were examined in both vacuum-packed bags and control packaging bags. The results showed that the acid value, peroxide value, relative conductivity and mildew rate of peanut were maintained at a lower level and germination rate was maintained at a higher level in vacuum-packed bags than in control packaging bags. The storage quality of peanut in vacuum-packed bags was better than in control packaging bags. The order of different vacuum degree of vacuum-packed bags from good to bad according to storage quality of peanut was－0.06 MPa>－0.09 MPa>－0.03 MPa, and －0.06 MPa was the most beneficial vacuum degree for the peanut storage
