摘要:

为筛选适用于牛肉的天然抗氧化剂并优化其应用工艺,明确天然抗氧化剂对牛肉抗氧化能力和风味的影响,以8种香辛料提取物为研究对象,以1,1-二苯基-2-三硝基苯肼(DPPH)自由基清除率、2,2'-联氮双(3-乙基苯并噻唑啉-6-磺酸)(ABTS)自由基清除率、色差和硫代巴比妥酸反应物(thiobarbituric acid reactive substances, TBARS)值为评价指标,筛选抗氧化效果最佳的香辛料提取物;以TBARS值、红度(a*)和总巯基含量为指标,通过单因素实验结合响应面法,优化该提取物处理牛肉的质量分数、处理时间与液料比,并分析最优工艺条件下提取物处理前后牛肉挥发性成分的变化。结果表明,8种香辛料提取物中,百里香提取物的抗氧化效果最优;经响应面法优化得到百里香提取物处理牛肉的最佳工艺条件为质量分数0.15%、处理时间30 min、液料比3∶1(mg·L-1)。该工艺条件可显著抑制牛肉的脂肪和蛋白质氧化,降低TBARS值,维持较高的红度和总巯基含量;挥发性成分分析显示,百里香提取物处理可减少牛肉氧化异味成分的生成,同时保留其醛类、酯类等特征风味成分,提升产品风味品质。本研究为百里香提取物在牛肉天然保鲜与品质提升中的应用提供了理论依据与技术支撑。

Abstract:

To screen natural antioxidants suitable for beef, optimize their application process, and clarify the effects of natural antioxidants on the antioxidant capacity and flavor of beef, eight spice extracts were investigated, using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging rate, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging rate, color difference, and thiobarbituric acid reactive substances (TBARS) value as evaluation indicators, the spice extract with the best antioxidant effect was selected. Taking TBARS value, redness (a*), and total sulfhydryl content as indicators, the mass fraction of the extract, treatment time and liquid-to-solid ratio for treating beef were optimized through single-factor experiments combined with response surface methodology. Changes in volatile components of beef before and after treatment under the optimal process conditions were analyzed. The results showed that among the eight spice extracts, thyme extract exhibited the best antioxidant effect. The optimal process conditions for treating beef with thyme extract obtained by response surface methodology were mass fraction of 0.15%, treatment time of 30 min, and liquid-to-solid ratio of 3∶1 (mg·L-1). Under these conditions, lipid and protein oxidation of beef were significantly inhibited, TBARS value was reduced, and high redness and total sulfhydryl content were maintained. Volatile component analysis revealed that thyme extract treatment reduced the generation of oxidative off-odor compounds in beef while retaining characteristic flavor components such as aldehydes and esters, thereby improving the flavor quality of the product. This study provides a theoretical basis and technical support for the application of thyme extract in the natural preservation and quality enhancement of beef.
