摘要: 以DPPH和ABTS自由基清除率为考查指标,探究不同储存时间、pH值、金属离子、储存温度及人工模拟消化系统对兜唇石斛发酵多肽Asp-Asp-Asp-Tyr(DDDY)和Asp-Tyr-Asp-Asp(DYDD)抗氧化活性的影响,并进一步研究2种发酵多肽的稳定性。结果表明:随着储存时间的延长,DDDY和DYDD的DPPH和ABTS清除率均明显下降,DPPH清除率在储存16 h后分别下降了约73.43%和73.22%;DDDY和DYDD在酸性或弱酸性环境下的稳定性较好,当pH值为2.0~12.0时,其ABTS清除率分别下降了约66.00%和70.81%,而对DPPH清除率的影响不大;金属离子会明显提高2种发酵多肽的ABTS清除率,其中受Na+、K+和Fe3+这3种金属离子影响较大;过高和过低的储存温度均会降低2种发酵多肽的DPPH和ABTS清除率,其中DYDD的ABTS清除率受储存温度影响较大;DDDY和DYDD的抗氧化活性在人工模拟消化系统中随着消化作用时间的延长均明显降低。2种发酵多肽的稳定性受环境影响较大,未来可通过包埋或基团连接等方式深入研究提高其稳定性的路径。Abstract: The effects of different storage time, pH value, metal ions, storage temperature and artificial simulation of digestive system on the antioxidant activities of fermented peptides Asp-Asp-Asp-Tyr (DDDY) and Asp-Tyr-Asp-Asp (DYDD) of Dendrobium aphyllum were investigated using DPPH and ABTS free radical scavenging rate as indexes. The stability of the two fermented peptides was further studied. The results showed that the DPPH and ABTS clearance rates of DDDY and DYDD decreased significantly with the increase of storage time, and the DPPH clearance rate decreased by about 73.43% and 73.22%, respectively, after 16 hours of storage. The stability of DDDY and DYDD was better in acidic or weakly acidic environment, and the ABTS clearance rate of DDDY and DYDD decreased by about 66.00% and 70.81% when the pH value was 2.0~12.0, respectively. Metal ions could significantly improve the ABTS clearance rate of the two fermented peptides, which was greatly affected by three metal ions: Na+, K+ and Fe3+. Too high and too low storage temperature decreased the DPPH and ABTS clearance rates of the two fermented peptides, and the ABTS clearance rate of DYDD was greatly affected by storage temperature. The antioxidant activity of DDDY and DYDD decreased significantly with the prolongation of digestion time in the artificial simulated digestive system. The stability of the two fermented peptides was greatly affected by the environments, and the path to improve their stability could be further studied through embedding or group linking in the future.
