摘要:以 1,1-二苯基-2-三硝基苯肼自由基(DPPH•)清除活性为评价指标,在评价了天然色素番茄红素和天然
防腐剂啤酒花中的各种活性成分(啤酒花浸膏、α-酸、β-酸和六氢 β-酸)单一溶液的抗氧化活性基础上,考察
了番茄红素分别与啤酒花浸膏、α-酸、β-酸、六氢 β-酸复配体系的协同抗氧化性能及复配液在不同温度和紫外
线照射不同时间下的稳定性。结果表明:番茄红素的抗氧化活性最强,其清除 DPPH•的 IC 50 为 8.73 mg/L;当番
茄红素质量浓度为 4 mg/L 时,其与啤酒花活性成分在中低质量比下,各复配体系协同抗氧化作用大小依次为番茄
红素/β-酸>番茄红素/六氢 β-酸>番茄红素/啤酒花浸膏>番茄红素/α-酸。50 ℃时,与 β-酸单组分溶液相比,番茄
红素/β-酸复配体系中 β-酸的稳定性提高 26.87%;与番茄红素单组分溶液相比,番茄红素/β-酸复配体系中番茄红
素的稳定性提高 11.27%;70 ℃时,与 β-酸单组分溶液相比,番茄红素/β-酸复配体系中 β-酸稳定性提高 40.86%,
与番茄红素单组分溶液相比,番茄红素/β-酸复配体系中番茄红素的稳定性提高 19.07%,且紫外线照射 10 h 各复
配体系吸光度值变化率维持在 80%以上,稳定性优异。

Abstract: The antioxidant activity of single solution of natural lycopene and hops active ingredients (hops
extract, α-acids, β-acids and hexahydro β-acids) was evaluated using the scavenging activity of
1,1-diphenyl-2-picrylhydrazyl radical (DPPH•) as evaluation index. Then, the synergistic antioxidant
properties of mixture solutions of lycopene with hops extract, α-acids, β-acids and hexahydro β-acids were
determined and the stability of mixture solutions at different temperatures and under ultraviolet irradiation
for different time. The results showed that the antioxidant activity of lycopene was the strongest, and it's
scavenging DPPH• IC 50 was 8.73 mg/L. When the mass concentration of lycopene was 4 mg/L, with the
active ingredients of hops at low to medium mass ratio the synergistic antioxidant effect of each mixture
solution was in order lycopene/β-acids > lycopene/hexahydrogen β-acids > lycopene/hops extract >
lycopene/α-acids. The stability of β-acids in the mixture solution of lycopene/β-acids was 26.87% and
40.86% higher than that of the single solution of β-acids at 50 and 70 ℃, respectively. While the stability
of lycopene increased by 11.27% and 19.07%, higher than that of the single solution of lycopene,
respectively. Moreover, the absorbance value change rate of all mixture solutions was maintained above
80% after ultraviolet irradiation for 10 h, and the stability was excellent.
