摘要

针对鲜切肉苁蓉易出现褐变和品质劣变的问题,该研究以新疆荒漠肉苁蓉为研究试材,在(4±0.5) ℃条件下,采用气调包装(4%O2+2%CO2+94%N2、4%O2+4%CO2+92%N2、4%O2+6%CO2+90%N2)进行处理,采用L*值、ΔE、褐变度、硬度、水分含量、呼吸强度、维生素C含量、总酚含量和菌落总数等指标评价气调包装对鲜切肉苁蓉褐变及品质的影响。结果表明,气调包装处理能有效抑制鲜切肉苁蓉在贮藏过程中褐变和品质劣变,且以4%O2+6%CO2+90%N2气调包装保鲜效果最佳。该处理能有效抑制贮藏期间鲜切肉苁蓉多酚氧化酶(polyphenol oxidase,PPO)、过氧化物酶(peroxidase,POD)活性(P<0.05)、延缓其褐变过程。此外,该条件可显著抑制鲜切肉苁蓉呼吸强度,延缓水分、维生素C及总酚含量的下降(P<0.05),并有效抑制了失重率和菌落总数的上升,较好地维持了鲜切肉苁蓉的感官品质,贮藏期延长至8 d。该研究说明,在低温条件下,4%O2+6%CO2+90%N2处理能有效保持鲜切肉苁蓉贮藏品质,该实验结果可为鲜切肉苁蓉采后贮运技术的研究提供理论依据。

Abstract

For the problems of browning and quality deterioration of fresh cut Cistanche deserticola, in this research, Cistanche deserticola of Xinjiang was used as experimental material and treated with modified atmosphere packaging (4%O2+2%CO2+94%N2, 4%O2+4%CO2+92%N2, and 4%O2+6%CO2+90%N2) at (4±0.5) ℃. The parameters, including the L* value, ΔE, browning degree, hardness, moisture content, respiratory intensity, vitamin C content, total phenol content, and total bacterial count were used to evaluate the effects of modified atmosphere packaging on browning and storage quality of fresh-cut Cistanche deserticola. Results showed that all the modified atmosphere packaging could effectively inhibit browning and quality deterioration of Cistanche deserticola during storage. The optimal modified atmosphere packaging was the 4%O2+6%CO2+90%N2, which could effectively inhibit the activities of polyphenol oxidase (PPO) and peroxidase (POD) and delay the browning of Cistanche deserticola during storage (P<0.05). In addition, the respiratory intensity was inhibited and the decreases in water content, vitamin C, as well as total phenol contents, were significantly delayed (P<0.05). Furthermore, the weightlessness rate and total bacterial count were effectively inhibited by 4%O2+6%CO2+90%N2 modified atmosphere packaging, the storage period was extended to 8 days using this method. In conclusion, these results demonstrated that the storage quality of fresh-cut Cistanche deserticola could be effectively maintained by the treatment of 4%O2+6%CO2+90%N2 under low-temperature conditions. This study could provide a theoretical basis for the study of postharvest storage and transportation technology of fresh-cut Cistanche deserticola.
