Maize, millet, rice and sorghum are staple cereals and major source of micronutrients for rural dwellers of Northeast Nigeria. These cereals were randomly sampled form the open markets and investigated for the levels of Iron (Fe) and Zinc (Zn) with a view to provide supportive monitoring information on possible dietary deficiency implications. The standard calibration method of flame atomic absorption spectrometry was used for the determination of Fe and Zn in the cereals. The results of the analysis show average Fe concentrations in cereals: Millet (10.28±2.38µg/g), Maize (5.26± 1.41µg/g), Sorghum (11.03±5.32µg/g) and Rice (6.67±5.94µg/g), and average Zn concentrations in cereals, Millet (5.89±0.88µg/g), Maize (3.92±0.91µg/g), Sorghum (3.84±0.92µg/g), Rice (1.80±0.32µg/g). This study revealed low levels of Zn and Fe in the cereal grains from the study areas, an observation that might be a risk factor for micronutrient malnutrition in the populations of rural dwellers of this region that depend so much on these cereals in their diets. Thus although exposure effects could be additive for Fe where similar foods are eaten, the Zn and Fe contents of the cereal grains may also be hampered from full absorption in the body due to lack of aiding diet components and certain cultural practices.
玉米、小米、大米和高粱是尼日利亚东北部农村居民的主要谷物和微量营养素的主要来源。从开放市场随机抽取这些谷物,调查其铁(Fe)和锌(Zn)水平,以期就可能的膳食缺乏问题提供支持性监测信息。采用火焰原子吸收光谱法测定谷物中铁和锌的标准校准方法。分析结果显示,谷子(10.28±2.38µg/g)、玉米(5.26±1.41µg/g)、高粱(11.03±5.32µg/g)、大米(6.67±5.94µg/g)中铁的平均浓度;谷子(5.89±0.88µg/g)、玉米(3.92±0.91µg/g)、高粱(3.84±0.92µg/g)、大米(1.80±0.32µg/g)中锌的平均浓度。这项研究显示,研究地区的谷物中锌和铁的含量较低,这一观察结果可能是该地区农村居民微量营养素营养不良的一个危险因素,因为他们在饮食中非常依赖这些谷物。因此,尽管在食用类似食物的地方,暴露效应可能是铁的累加性,但由于缺乏辅助饮食成分和某些文化习俗,谷物中的锌和铁含量也可能受到阻碍,无法在体内完全吸收。

Food borne diseases are of public health importance. A food poisoning incident occurred on 24th October 2010 amongst 22 mourners who had consumed porridge one day after the funeral rites of a child in Mubachi Sub-Location of Suba West Division in Migori District, south western Kenya. An investigation of the incident was conducted with only two objectives in mind, i.e. (1) to document the poisoning incident for learning and for future reference and (2) to deter- mine the causative factors so as to recommend appropriate public health interventions. Both patient and clinician interviews were conducted. A total of seven patients were interviewed. Patients denied any knowledge of environmental contamination within or without the homestead. They also denied care-less handling of tobacco farming pesticides. The investigation es- tablished that the water used in preparing the porridge had been left uncovered on the verandah overnight and it had devel- oped a brownish discoloration. The porridge was prepared from a mixture of cassava and sorghum flour in the ordinary way and mourners had consumed between 250ml-500ml in clean plastic cups. The victims developed signs and symptoms about 30-60 minutes after consumption. Children were affected first. They collapsed, vomited, complained of abdominal pains and had diarrhea. Other signs and symptoms occurring in both adults and children were fever, generalized body weakness, and profuse sweating. The frequency distribution of signs and symp-toms showed 63% generalized body weak- ness, 50% vomiting, 27% nausea, 23% abdominal pain, 14% diarrhea, 9% cough and 5% restlessness. The attack rate was 100%. The suspected cause of poisoning was either hydrocyanic acid in cassava flour or pesticide contamination of the water used in preparing the porridge. In order to arrive at a differential diagnosis, an internet-based literature search was con-ducted to provide an overview of the signs and symptoms associated with the suspected toxicological agents. On this basis, hydrocyanic acid, organochlorine and pyrethroid pesticides were ruled out. There was a near-perfect match between the signs and symptoms of the poisoning to classical signs and symptoms of organophosphate poisoning in the literature. We conclude that the poisoning agent was an organophosphate. Though the victims denied any knowledge of environmen- tal contamination, we strongly believe that the water used in preparing the porridge had been chemically contaminated ei- ther by careless handling of pesticides or foul play. We recommend that since the affected area and indeed the rest of Migo- ri district are tobacco growing areas, there is need for mass health education on the safe handling and disposal of pesticide products as these are widely used. Pesticide dispensing outlets should provide also pesticide safety education to customers on each pesticide sold to encourage safe use and handling.
食源性疾病对公共卫生具有重要意义。2010年10月24日,在肯尼亚西南部Migori县Suba West分部Mubachi分区,22名哀悼者在一名儿童的葬礼后一天食用了粥,发生了食物中毒事件。对该事件进行调查的目的只有两个,即(1)记录中毒事件,以供学习和今后参考;(2)阻止-确定致病因素,以便建议适当的公共卫生干预措施。对患者和临床医生进行了访谈。共采访了7名患者。患者否认对宅基地内外的环境污染知情。他们还否认对烟草种植的农药处理不当。调查证实,用于煮粥的水被放在阳台上过夜,并且已经变成了褐色。这种粥是由木薯粉和高粱粉以普通方式混合制成的,哀悼者在干净的塑料杯中喝下250毫升至500毫升。受害者在食用后约30-60分钟出现体征和症状。儿童首先受到影响。他们晕倒、呕吐、抱怨腹痛和腹泻。成人和儿童均出现的其他体征和症状为发热、全身无力和大量出汗。体征和症状的频率分布为全身无力63%,呕吐50%,恶心27%,腹痛23%,腹泻14%,咳嗽9%,烦躁5%。攻击率为100%。中毒的原因可能是木薯粉中的氢氰酸,或者是煮粥所用的水被农药污染。为了得出鉴别诊断,进行了基于互联网的文献检索,以提供与疑似毒理学因子相关的体征和症状的概述。在此基础上,排除了氢氰酸、有机氯和拟除虫菊酯类农药。中毒的症状和体征与文献中有机磷中毒的典型症状和体征几乎完全吻合。我们断定中毒剂是一种有机磷。虽然受害者否认对环境污染有任何了解,但我们坚信,煮粥所用的水受到了化学污染——要么是农药的粗心处理,要么是谋杀。我们建议,由于受影响地区以及Migo- ri区的其他地区都是烟草种植区,有必要就农药产品的安全处理和处置进行大规模健康教育,因为农药产品被广泛使用。除害剂配售点亦应就所售除害剂向顾客提供除害剂安全教育,鼓励顾客安全使用和处理。

Three hundred and ninety-three samples of dairy products (124 samples of white cheese, 61 samples of cream cheese, 76 samples of Kashar cheese, and 132 samples of butter), 91 samples of cashew nut and 97 macademia nut marketed in Eastern Province, Saudi Arabia during September 2010-September 2011, were analyzed for aflatoxin M1 (AFM1), total aflatoxin and AFB1 by microtitre plate enzyme linked immunosorband assay (ELISA) The incidence of AFM1 contamination in dairy products analyzed was 82%. Total aflatoxin contamination was determined in 84 (92.3%) of 91 cashew nut and in 88 (90.7%) of 97 macademia nut whereas total aflatoxin contamination was not detected in 3 (3.2%) of 91 cashew nut samples and in 12 of 97 macademia nut samples. AFB1 was found in 84 (92.3%) of 91 cashew nut and in 83 (85.5%) of 97 samples of macademia nut samples. AFM1 levels in 3 (2.4%) white cheese, 4 (3.0%) of butter, 2 (3.2%) in cream cheese and 5 (6.5%) of Kashar cheese samples were found higher than the maximum acceptable levels as set by European Union.Continuous surveillance program may be warranted to monitor regularly the occurrence of aflatoxins in foodstuffs.

The Choice of rice varieties by farmers and consumers and the rate at which farmers in Ebonyi state go for new rice varieties at the expense of indigenous varieties have become a source of worry to scientists in Nigeria. We assessed the cooking quality and physico-chemical characteristics of 15 selected indigenous and five newly introduced hybrid rice varieties grown in Ebonyi State, Nigeria. Significant variation (P<0.05) was detected among the 20 rice varieties for all the traits evaluated. The results showed that all the five newly introduced hybrid rice varieties do not swell appreciably during cooking. The grains of Cv.“China” had the highest elongation values of 3.2 ± 0.00 mm. “E4197” has the best physical appearance but easily dissolves in water during cooking. Most of the physico-chemical characteristic such as amylose, amylopectin, gel consistency and gelatinization temperature were significantly correlated (positively or negatively) with some of the cooking quality traits (elongation during cooking, solids in cooking water and optimum cooking time), indicating that efforts aimed at selecting rice varieties with improved cooking quality traits would warrant a consideration of the physico-chemical attributes of the rice grain. The overall cooking quality and physico-chemical attributes of some of the indigenous rice varieties were even relatively better than the newly introduced hybrid varieties. Farmers should, therefore, be critical in accepting new varieties that may not be comparably outstanding in cooking quality and physico-chemical characteristics, in order to preserve the integrity of the all-cherished indigenous rice varieties of Ebonyi State, Nigeria.
农民和消费者对水稻品种的选择,以及Ebonyi州农民以牺牲本土品种为代价选择新水稻品种的速度,已经成为尼日利亚科学家担忧的一个问题。我们评估了在尼日利亚埃邦伊州种植的15个精选的本地水稻品种和5个新引进的杂交水稻品种的蒸煮质量和理化特性。20个水稻品种间各性状均存在显著差异(P<0.05)。结果表明,5个新引进的杂交稻品种在蒸煮过程中均没有明显的膨胀现象。Cv的颗粒。“China”的伸长率最高,为3.2±0.00 mm,“E4197”的物理外观最好,但在烹饪过程中容易溶于水。直链淀粉、支链淀粉、凝胶稠度和糊化温度等大部分理化性状与部分蒸煮品质性状(蒸煮伸长率、蒸煮水固含量和最佳蒸煮时间)显著相关(正相关或负相关),表明在选择蒸煮品质性状较好的水稻品种时,必须考虑稻米的理化性状。部分地方水稻品种的整体蒸煮品质和理化性状甚至相对优于新引进的杂交品种。因此,农民在接受可能在烹饪质量和物理化学特性方面不那么突出的新品种时应持关键态度,以便保持尼日利亚埃邦伊州极为珍贵的本土水稻品种的完整性。

Tea is consumed throughout the world, both for pleasure and therapeutic purpose. Most people will be unaware of their involuntary exposure to residues of pesticide lingering in processed tea and so possibly transferring into infusion of tea. The objective of this trial was not only to provide a simple residue analytical method to evaluate the safe application rate of emamectin benzoate for tea crops but also suitable dosage in tea crop. The residues of emamectin benzoate were deter- mined by high performance liquid chromatography equipped with fluorescence detector. Tea samples extracted with ace- tone/water (70:30 v/v), the extract were cleaned up by liquid - liquid extraction under the fortified level 0.02 µg/mg to 2.0 µg/mg, the recovery ranged from 80.90 % to 115.72 % for black tea, 82.72 % to 106.06 % for sundried green leaves, 83.85 % to 90.64 % for tea brew and 86.33 % to 104.19 % for soil. The limit of detection and limit of quantification of the method were 0.01 µg/mg and 0.02 µg/mg.
茶在世界各地都被消费,既用于娱乐,也用于治疗。大多数人不会意识到他们无意中接触到残留在加工茶中的农药残留物,因此可能会转移到茶的冲泡中。本试验的目的是为评价苯甲酸埃维菌素在茶树中的安全施用量和适宜用量提供一种简便的残留分析方法。采用荧光检测器高效液相色谱法测定了苯甲酸埃维菌素的残留量。用ace- tone/water (70:30 v/v)萃取的茶叶样品,在强化浓度0.02µg/mg ~ 2.0µg/mg下进行液-液萃取,对红茶的回收率为80.90% ~ 115.72%,对干绿叶的回收率为82.72% ~ 106.06%,对茶叶的回收率为83.85% ~ 90.64%,对土壤的回收率为86.33% ~ 104.19%。方法的检出限和定量限分别为0.01µg/mg和0.02µg/mg。

The present investigation was conducted to study the effect of processing (soaking and germination) and cooking methods (ordinary cooking and autoclaving) on the chemical composition, sugars and phytic of two varieties soybean seeds, Giza, 21 and Giza, 35. The processing and cooking methods caused increase in both protein and crude fiber contents. Meanwhile, crude oil and carbohydrates contents were decreased of the studied soybean seeds. Generally, the processing and cooking methods resulted in a decrease of raffinose, stachyose, verbascose, maltose and sucrose accompanied by an increase in glucose. These resulted revealed that the processing (soaking and germination) and cooking methods (ordinary cooking and autoclaving) was more effective in eliminating the contents of oligosaccharides and phytic acid in both varieties soybean seeds.
以吉萨21号和吉萨35号两个大豆品种为研究对象,研究了不同处理方式(浸泡和发芽)和蒸煮方式(普通蒸煮和高压灭菌)对其化学成分、糖和植物性的影响。加工方法和蒸煮方法均使蛋白质和粗纤维含量增加。同时,大豆种子的原油含量和碳水化合物含量均有所降低。一般来说,加工和烹饪方法导致棉子糖、水苏糖、毛蕊糖、麦芽糖和蔗糖的减少,同时葡萄糖的增加。结果表明,处理方法(浸泡和发芽)和蒸煮方法(普通蒸煮和高压灭菌)对两个品种大豆种子中低聚糖和植酸含量的去除效果更好。

Policy makers at global, national and local levels are more than ever concerned about the rising trend in child malnutrition in Sub-Saharan Africa and how it can be curtailed in the context of general food and basic-needs policies. To support programme setting at the local government level, this study was conducted to examine the relative importance of environmental and socio economic correlates of child malnutrition. Primary data were collected through a well structured questionnaire and analysed using Z-score indices and probit model.Our results reveal that 46% of the children are stunted, 6% under weight and 21% wasted. Our model estimation identified the age of the child, diarrhoea infection and poor sanitation as key factors that increases the likelihood of malnutrition in the study area. This reflects the relative importance of environ- mental factors in the study area. Socioeconomic factors were less robust but were consistent with previous empirical studies in terms of direction of association. The study recommends that government and other stakeholders should pursue sanitation/ hygiene programmes and public enlightenment programmes on the dangers of poor sanitation and diarrhoea.
全球、国家和地方各级的决策者比以往任何时候都更加关注撒哈拉以南非洲儿童营养不良的上升趋势,以及如何在总体粮食和基本需求政策的背景下遏制这一趋势。为了支持地方政府层面的项目设置,本研究旨在检验环境和社会经济因素对儿童营养不良的相对重要性。通过结构良好的问卷收集原始数据,并使用Z-score指数和probit模型进行分析。我们的研究结果显示,46%的儿童发育不良,6%的儿童体重不足,21%的儿童消瘦。我们的模型估计确定了儿童的年龄,腹泻感染和卫生条件差是增加研究地区营养不良可能性的关键因素。这反映了环境因素在研究区域的相对重要性。社会经济因素较弱,但在关联方向上与先前的实证研究一致。该研究建议,政府和其他利益相关者应推行环境卫生/个人卫生计划,并开展关于环境卫生不良和腹泻危险的公众启蒙计划。

The aim of this study was to characterize the Bombacopis glabra nut oil (Malvaceae-Bombacoideae) by the determination of its lipid content and fatty acid composition with emphasis on the cyclopropenoid fatty acids (CPFA). The lipids were obtained by five different extraction conditions:(raw almonds: maceration with ethyl ether (I-MA) and n-hexane (II-MA), both at room temperature, and Soxhlet extraction with hexane for 6 (III-MA) and 12 h (IV-MA) and toasted almond: maceration with hexane at room temperature (V-MA)). Additionally, the oxidation stability of oil by the Rancimat test and the boiling point by thermal analysis (technical TG / DTG) were evaluated. The oil content ranged from 34.99 (I-MA) to 47.36% (IV-MA); oxidation stability was 4.18 h and the boiling point was 373.37 ℃. It should be noted that results about thermal and oxidative stability are been reported for the first time with respect to Bombacopis glabra nut oil. The major oil constituents were palmitic acid (56.06%) and esterculico (24.83%). The high percentage of CPFA oil, determined by NMR 1 H (26.2 to 30.9%) and GC-FID (26.5%), reinforce that the kernels of this species are not suitable for human consumption.
以环丙烯脂肪酸(CPFA)为主要成分,对光绵猴坚果油(malvacae - bombacoideae)的脂质含量和脂肪酸组成进行了研究。通过5种不同的提取条件(生杏仁:在室温下用乙醚(I-MA)和正己烷(II-MA)浸渍,用己烷索氏浸渍6 (III-MA)和12 h (IV-MA),烤杏仁:在室温下用己烷浸渍(V-MA))得到脂质。此外,还对油的氧化稳定性和沸点进行了热分析(技术TG / DTG)。含油量为34.99 (I-MA) ~ 47.36% (IV-MA);氧化稳定性为4.18 h,沸点为373.37℃。值得注意的是,本文首次报道了光斑Bombacopis glabra坚果油的热稳定性和氧化稳定性。主要油脂成分为棕榈酸(56.06%)和酯酸(24.83%)。核磁共振1 H(26.2 - 30.9%)和气相色谱- fid(26.5%)测定的CPFA油的高百分比强化了该物种的仁不适合人类食用。
