摘要:

在不同巴氏杀菌温度、时间处理三华李果汁,以总多酚、花青素、VC含量及抗氧化能力(DPPH自由基清除能力)为指标,研究巴氏杀菌条件对三华李果汁主要抗氧化成分的影响。研究设计12组巴氏杀菌处理条件(82℃、5s,82℃、15s,82℃、30s,82℃、60s,88℃、5s,88℃、15s,88℃、30s,88℃、60s,93℃、5s,93℃、15s,93℃、30s,93℃、60s)。结果表明:不同温度和杀菌时间只对VC含量和DPPH自由基清除能力有显著影响,而对总多酚和花青素的含量无显著性影响。88℃、15s可最大程度地保留VC含量(4.24mg/L),而在93℃、60s时DPPH自由基清除率达到最高(94.6%)。

Abstract:

Sanhua plum juice was treated under different pasteurization time/temperature conditions (82 ℃ for 5 s, 82 ℃ for 15 s,
82 ℃ for 30 s, 82 ℃ for 60 s, 88 ℃ for 5 s, 88 ℃ for 15 s, 88 ℃ for 30 s, 88 ℃ for 60 s, 93 ℃ for 5 s, 93 ℃ for 15 s, 93 ℃ for 30 s, and
93 ℃ for 60 s). The contents of antioxidant compounds including total phenolic compounds, anthocyanin, vitamin C and antioxidant
capacity (DPPH radical scavenging capacity) were investigated under different pasteurization conditions. Results indicated that different
temperatures and treatment times could affect vitamin C content and DPPH radical scavenging capacity significantly, while having no
effect on total phenolic compounds or anthocyanin. The treatments at 88 ℃ for 15 s and 93 ℃ for 60 s were the optimal conditions for
preserving total vitamin C content (4.24 mg/L) and DPPH radical scavenging capacity (94.6%), respectively.

Key words: Sanhua plum juice, pasteurization, total phenolic compounds, anthocyanin, total vitamin C, total antioxidant capacity
