Abstract

Background and Aim: Irradiation has become a preferred method for pork preservation in recent years. Electron-beam irradiation is notably recognized for its feasibility and safety among various irradiation methods. This meta-analysis study aims to elucidate the impact of electron-beam irradiation on oxidation parameters, color, sensory attributes, and microbiological conditions in pork. Materials and Methods: A total of 79 data from 22 articles were aggregated into an extensive database. The irradiation dose ranged from 0 to 20 kGy in this current meta-analysis. The observed parameters encompassed oxidation, color, sensory attributes, and microbiological conditions. A mixed-model approach was used to perform the meta-data analysis, in which irradiation dose was treated as fixed effects and distinct studies (articles) as random effects. Results: Electron-beam irradiation resulted in an increase in thiobarbituric acid-reactive substances levels and peroxide-oxygen value of pork (p < 0.01). Conversely, total volatile-base-nitrogen values (p < 0.05) were observed. Following irradiation, the pH value, lightness (L*), redness (a*), and yellowness (b*) remained unaffected. Pork color tended to decrease after irradiation treatment (p = 0.095 and p = 0.079, respectively) at 7 and 14 days of storage. The irradiation process resulted in an increase in the values of texture and juiciness parameters (p < 0.05). However, electron-beam irradiation resulted in decreased overall acceptability (p = 0.089). In terms of microbiological status, electron-beam irradiation led to a reduction in the populations of Salmonella (p < 0.01), Escherichia coli (p < 0.01), Listeria monocytogenes (p < 0.05), and coliforms (p < 0.05) at 7 and 14 days of storage. Conclusion: Electron-beam irradiation enhances lipid peroxidation in porcine meat. The color of the meat remained unchanged after treatment. However, with regard to sensory properties, electron-beam irradiation showed a tendency to decreased overall acceptability. Most microbiological parameters decreased following electron-beam irradiation. Keywords: electron beam, irradiation, meat, meta-analysis, pork.

电子束照射后猪肉的质量：荟萃分析研究

背景和目的：近年来，辐照已成为猪肉保存的首选方法。在各种辐照方法中，电子束辐照因其可行性和安全性而备受认可。这项荟萃分析研究旨在阐明电子束辐照对猪肉氧化参数、色泽、感官属性和微生物条件的影响：将 22 篇文章中的 79 个数据汇总到一个庞大的数据库中。在本次荟萃分析中，辐照剂量从 0 到 20 kGy 不等。观察到的参数包括氧化、颜色、感官属性和微生物条件。元数据分析采用混合模型法，其中辐照剂量作为固定效应，不同研究（文章）作为随机效应：结果：电子束辐照导致硫代巴比妥酸反应物质水平和猪肉过氧化氧值升高（p < 0.01）。相反，总挥发性碱基氮值（p < 0.05）则有所下降。辐照后，pH 值、亮度（L*）、红度（a*）和黄度（b*）均未受影响。辐照处理后，猪肉的颜色在储存 7 天和 14 天后有下降趋势（分别为 p = 0.095 和 p = 0.079）。辐照过程导致质地和多汁度参数值增加（p < 0.05）。然而，电子束辐照导致总体可接受性下降（p = 0.089）。在微生物状况方面，电子束辐照导致沙门氏菌（p < 0.01）、大肠埃希氏菌（p < 0.01）、单核细胞增生李斯特菌（p < 0.05）和大肠菌群（p < 0.05）在贮藏 7 天和 14 天时的数量减少：结论：电子束辐照会增强猪肉的脂质过氧化反应。结论：电子束辐照会增强猪肉的脂质过氧化反应。然而，在感官特性方面，电子束辐照有降低整体可接受性的趋势。关键词：电子束；辐照；肉；荟萃分析；猪肉。
