| 1 | 使用气态臭氧体外处理控制储存埃及带壳花生中黄曲霉和黄曲霉毒素B_(1)的潜力显示文摘研究考察在不同水分活度(aw,0.89~0.97=13.1%~24%水分含量)和体外25℃条件下,气态臭氧(O_(3))对黄曲霉菌株(a)孢子萌发,(b)菌丝生长,(c)产黄曲霉毒素B_(1)(AFB_(1))的影响。此外,以埃及花生为研究对象,在0.93 aw下,带壳花生接种两种浓度的黄曲霉分生孢子(103、105分生孢子/g)置于气态O_(3)中然后储存。在所有情况下,臭氧处理设置为30 min,流速为6 L/min。通常,大于100 ppm浓度的O_(3)48 h内,可显著抑制黄曲霉菌株(EGP-B07;SRRC-G 1907)在特定酵母蔗糖培养基上的分生孢子萌发。然而,浓度高达300 ppm的O_(3),对黄曲霉的生长和菌落的扩展没有影响。相同浓度在0.89 aw时能显著影响AFB_(1)的产生。0.93 aw条件下,储存带壳花生中的两种黄曲霉菌株在100~400 ppm O_(3)的数量显著减少。然而,两接种量水平下,AFB_(1)产量仅在400 ppm O_(3)处理中显著降低。对使用O_(3)气体控制采后带壳花生中的黄曲霉种群和AFB_(1)的结果进行了讨论。 | Yousef Sultan Naresh Magan | 2021 | 粮油食品科技2021，29，6： | 3 |

| 11 | 非生物储存因素互作对储藏土耳其带壳榛子呼吸、干物质损失和黄曲霉毒素B_(1)污染的影响显示文摘榛子是一种具重要经济意义、世界各地广泛食用的坚果,易受黄曲霉感染和黄曲霉毒素的污染。以土耳其榛子为研究对象,旨在了解不同的温度和可利用水分下,自然存储的带壳榛子的量化呼吸速率、干物质损失(DML)和黄曲霉毒素B_(1)(AFB_(1))的污染等情况,以及榛子储存前附加接种黄曲霉对干物质损失和AFB_(1)污染的影响。榛子和相关菌群的最大呼吸作用发生在0.90~0.95水分活度(aw=12.5%~18%水分含量)的潮湿条件下。这导致25和30℃下储存5 d后,榛子损失约10%的DML。储存的带壳榛子+接种黄曲霉在25~30℃和小于0.90 aw下产生类似的最佳呼吸模式。事实上,在测试的最大水分水平0.90 aw的AFB_(1)污染是最高的;这样的污染水平超过了欧盟对这些坚果污染AFB_(1)的法定限制。两组研究中,DML与所有AFB_(1)数据之间的相关性表明,由于干燥或≥0.6%不良储存引起非常小的DML变化,可导致AFB_(1)污染超过欧盟法定限制。因此,有效干燥和安全监控储存对于最大限度地降低这种重要经济商品中AFB_(1)污染风险并避免消费者暴露于此类毒素是十分必要的。 | Kalliopi Mylona Angel Medina Naresh Magan | 2021 | 粮油食品科技2021，29，6： | 0 |
| 12 | Effect of Interacting Abiotic Storage Conditions on Respiration,Dry Matter Losses and Aflatoxin B_(1) Contamination of Stored Turkey’s Shelled Hazelnuts显示文摘Hazelnuts are an economically important nut which is consumed world-wide.It is prone to infection by Aspergillus flavus and contamination with aflatoxins.Taking Tukey’s hazelnuts as a research object,the objective of this study were to(a)quantify respiration rates and(b)dry matter losses(DMLs)and(c)aflatoxin B_(1)(AFB_(1))contamination of naturally stored shelled hazelnuts at different temperatures and water availabilities.Subsequently,shelled hazelnuts were inoculated with additional A.flavus inoculum prior to storage to examine effects on dry matter losses and on AFB_(1) contamination.Maximum respiration of hazelnuts and associated mycoflora was under wetter conditions of 0.90~0.95 water activity(aw=12.5%~18%moisture content).This resulted in between approx.10%DML at 25 and 30℃after 5 days storage.Inoculation and storage of shelled hazelnuts+A.flavus inoculum resulted in similar patterns of respiration with optimal levels at 25~30℃and>0.90 aw.Indeed,AFB_(1) contamination was highest at the maximum water levels tested of 0.90 aw.Indeed the contamination level exceeded the legislative limits set by the EU for AFB_(1) contamination of these nuts.Correlation between DMLs and all the AFB_(1) data in both sets of studies showed that very small changes in DML due to poor drying or storage of≥0.6%resulted in AFB_(1) contamination levels exceeding the EU legislative limits.Thus,efficient drying and safe monitored storage is necessary to minimise the risk of AFB_(1) contamination in this economically important commodity and to avoid exposure of consumers to such toxins. | Kalliopi Mylona Angel Medina Naresh Magan | 2021 | 粮油食品科技2021，29，6： | 0 |
| 13 | Potential for Control of A.Flavus and Aflatoxin B_(1)in Vitro and in Stored Egyptian Shelled Peanuts using Gaseous Ozone Treatment显示文摘The objective of this study was to examine the effect of gaseous ozone(O_(3))on(a)germination,(b)mycelial growth,(c)aflatoxin B1(AFB1)production by strains of Aspergillus flavus at different water activity(aw,0.89~0.97=13.1%~24%moisture content)and 25 oC in vitro.In addition,taking Egyptian peanuts as a research object,shelled peanuts at 0.93 aw were inoculated with two concentrations of A.flavus conidia(103,105 conidia/g)and exposed to gaseous O_(3) and then stored.In all cases,exposure was for 30 min at 6 L/min.Generally,>100 ppm O_(3) significantly inhibited conidial germination of A.flavus strains(EGP-B07;SRRC-G 1907)on a defined yeast sucrose medium within 48 hrs.However,exposure of growing colonies of A.flavus to O_(3) with up to 300 ppm,had no effect on subsequent colony extension.The same concentration significantly affected AFB1 production,but only at 0.89 aw.Populations of both A.flavus strains in stored shelled peanuts exposed at 0.93 aw were significantly decreased at 100~400 ppm O_(3).However,AFB1 production was only significantly reduced in the 400 ppm O_(3) treatments at both inoculum load levels.These results are discussed in the context of O_(3) gas use for controlling A.flavus populations and AFB1 in shelled peanuts post-harvest. | Yousef Sultan Naresh Magan | 2021 | 粮油食品科技2021，29，6： | 0 |
