Effect of paperboard packaging inner coated with preservation agents on fresh-keeping of honey peach

To investigate the preservation effect of paperboard packaging box with inner coating preservation agents, honey peach (Prunus persica L. cv.”fenghua”) was studied. The experimental treatments included paperboard packaging storaged at room temperature (25℃), paperboard packaging storaged at 4－6℃, packaging by the paperboard with inner coating layer stored at room temperature (25℃), packaging by the paperboard with inner coating layer stored at 4－6℃, no packaging storaged at 4－6℃ as low temperature control group, and no packaging storage at room temperature as normal control group. The results show that the paperboard packaging box with inner coating preservation agents of 0.8% nisin and 0.5% natamycin could effectively inhibit the respiration of Honey peach, maintain the peach flavor and flesh firmness, and can inhibit the texture changes effectively.
