Abstract

Aims: Enteric viruses are recognized as a major concern in health care and in the food sector in Canada. Novel clean-label strategies for controlling enteric viruses are sought in the food industry. In this study, we examined the antiviral potential of plant extracts and essential oils on murine norovirus 1 (MNV-1), hepatitis A virus (HAV), and herpes simplex virus 1 (HSV-1).

Methods and results: Inactivation of the viruses by grape seed, blueberry, green tea, and cranberry extracts and by rosemary and thyme essential oils was measured using plaque formation assay. Concentrations ranging from 50 to 200 000 ppm with a contact time of 90 min were tested. Grape seed extract at 10 000 ppm was the most effective (P < 0.05) at reducing MNV-1 and HAV infectious titers, respectively, by 2.85 ± 0.44 log10 and 1.94 ± 0.17 log10. HSV-1 titer was reduced by 3.81 ± 0.40 log10 at 1000 ppm grape seed extract.

Conclusions: Among the plant products tested, grape seed extract was found the most effective at reducing the infectious titers of MNV-1, HAV, and HSV.

评估精油和天然提取物对食源性病毒的抑制活性。

目的：在加拿大，肠道病毒被认为是医疗保健和食品行业的主要问题。食品行业正在寻求控制肠道病毒的新型清洁标签策略。在这项研究中，我们考察了植物提取物和精油对小鼠诺如病毒 1（MNV-1）、甲型肝炎病毒（HAV）和单纯疱疹病毒 1（HSV-1）的抗病毒潜力：使用斑块形成试验测定了葡萄籽、蓝莓、绿茶和蔓越莓提取物以及迷迭香和百里香精油对病毒的灭活作用。测试的浓度范围为 50 至 200,000 ppm，接触时间为 90 分钟。浓度为 10,000 ppm 的葡萄籽提取物对降低 MNV-1 和 HAV 感染滴度最有效（p < 0.05），分别降低了 2.85 ± 0.44 log10 和 1.94 ± 0.17 log10。在 1000 ppm 的葡萄籽提取物中，HSV-1 滴度降低了 3.81 ± 0.40 log10：结论：在测试的植物产品中，葡萄籽提取物在降低 MNV-1、HAV 和 HSV 感染滴度方面最为有效。
