摘要
色素大米因其生物活性化合物所带来的营养和健康益处而备受关注。尽管有这些优点,但色素稻米易受霉菌毒素污染的问题却令人十分担忧。这项研究考察了泰国七个色素大米品种的真菌生物群,重点研究了能够产生赭曲霉毒素 A(OTA)和柠檬素的真菌。研究分析了 110 个色素稻米样本,发现曲霉菌属(Aspergillus)占主导地位(50-82.35%),其次是青霉属(Penicillium)(12.50-70.59%)。从 Nigri 曲霉科(1/112)分离出的一个 A. carbonarius 和从 Circumdati 曲霉科(2/61)分离出的两个 A. steynii 和 A. flocculosus 产生了 OTA。不过,没有一种青霉产生 OTA,但柠檬青霉(128/280)明显产生柠檬素。研究发现,黑茉莉香米和红茉莉香米品种更容易产生霉菌毒素,而Luem Pua糯米和Hom Nil大米品种对这两种霉菌毒素的积累表现出更强的抵抗力。这些发现应能指导采取有针对性的战略,以降低霉菌毒素风险,确保色素稻米在食物链中的安全性。
Assessment of mycobiota in Thai pigmented rice: Insights into ochratoxin A and citrinin production by Aspergillus and Penicillium species
Pigmented rice has gained interest for its nutritional and health benefits attributed to its bioactive compounds. Despite these advantages, the vulnerability of pigmented rice to mycotoxin contamination poses a major concern. This study examined the mycobiota of seven Thai pigmented rice varieties, with a focus on fungi capable of producing ochratoxin A (OTA) and citrinin. The study analyzed 110 pigmented rice samples and found that the Aspergillus section Aspergillus was predominant (50–82.35%), followed by Penicillium species (12.50–70.59%). One isolate of A. carbonarius from Aspergillus section Nigri (1/112) and two isolates from Aspergillus section Circumdati (2/61)—A. steynii and A. flocculosus—produced OTA. However, none of the Penicillium species produced OTA, though citrinin production was notable in P. citrinum (128/280). The study found that the Black Jasmine rice and Red Jasmine rice varieties were more susceptible to mycotoxin production, while the Luem Pua glutinous rice and Hom Nil rice varieties displayed more resistance to the accumulation of both mycotoxins. These findings should guide targeted strategies to mitigate mycotoxin risks and ensure the safety of pigmented rice in the food chain.
期刊介绍:
The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
