It is evident that date fruits provide a wide variety of essential nutrients which impart potential human health benefits. In Bangladesh, the popularity of date and its consumption surge few-fold during Ramadan among Muslims owing to the profound emotion related to religious belief that breaking of dawn-to-dusk fasting with dates is fulfilling a Sunnah. The present study aimed to explore the microbiological quality of the five most popular fresh date samples (Nagal, Dhapas, Boroi, Morium, and Tunisia) purchased from different locations of Dhaka City, Bangladesh. Among 25 samples tested, 23 were observed to carry 3.30-5.65 Log CFU/gm aerobic bacteria and 3.30-5.36 Log CFU/gm yeasts and molds population. Coliform bacteria and were not found in any of the samples analyzed in this study. However, except Nagal and Boroi from Mohammadpur and Mirpur, respectively, none of the samples were found safe to consume according to the microbiological grade recommended by Woolworths Quality Assurance Standard (WQAS), 2009, as fresh dates with microbial load can cause food poisoning or even foodborne intoxication. Date samples with less or no processing is responsible for this contamination which can be subsided and eliminated by appropriate handling and hygiene practices during postharvest processing.
显然,椰枣提供了多种必需营养素,对人体健康具有潜在益处。在孟加拉国,由于与宗教信仰相关的深厚情感,即开斋时食用椰枣来打破从黎明到黄昏的禁食是履行一项圣行,在斋月期间,椰枣的受欢迎程度及其消费量激增数倍。本研究旨在探究从孟加拉国达卡市不同地点购买的五种最受欢迎的新鲜椰枣样本(纳加尔、达帕斯、博罗伊、莫里姆和突尼斯)的微生物质量。在测试的25个样本中,观察到23个样本携带3.30 - 5.65 Log CFU/g的需氧菌以及3.30 - 5.36 Log CFU/g的酵母菌和霉菌。在本研究分析的任何样本中均未发现大肠菌群。然而,根据伍尔沃思质量保证标准(WQAS,2009)推荐的微生物等级,除了分别来自穆罕默德布尔和米尔布尔的纳加尔和博罗伊外,没有一个样本被认为食用安全,因为微生物负荷高的新鲜椰枣可能会导致食物中毒甚至食源性中毒。加工较少或未加工的椰枣样本是造成这种污染的原因,在收获后加工过程中通过适当的处理和卫生措施可以减少和消除这种污染。
