The loss of vitamin B(12) in round herring meats during various cooking treatments was evaluated. Although amounts of vitamin B(12) were three times greater in the viscera (37.5 ± 10.6 μg/100 g fresh weight) than in the meats, about 73% of total vitamin B(12) found in the whole fish body (except for head and bones) were recovered in the meats (5.1 ± 1.0 μg of vitamin B(12)). The vitamin B(12) contents of the round herring's meats were significantly decreased up to ~62% during cooking by grilling, boiling, frying, steaming, and microwaving. There was, however, no loss of vitamin B(12) during vacuum-packed pouch cooking. Model experiment using hydroxocobalamin suggest that loss of vitamin B(12) is dependent on the degree of temperature and time used in conventional cooking, and is further affected by the concomitant ingredients of food. Retention of vitamin B(12) was not dependent on vacuum or temperature (or both) used in the vacuum-packed pouch cooking. 相似文献

This study examines food marketing to children on Greek television. Food advertisements broadcast in public and commercial channels during children’s programmes and programmes watched by family members are examined. The research took into consideration four different time periods of the second semester of 2011. 7 days in summer, 7 days in autumn, 4 weekends in autumn and five evenings in winter were examined. The total time of all advertisements counted was 25:28:06 h where the total time of food advertisements was 4:58:01 h. Food advertisements in summer counted to 12.47 % of the total number of advertisements. In autumn food advertisements counted to 30 % of all advertisements shown. On 4 weekends in autumn, food advertisements were equal to 29.47 % of total advertisements. In winter advertisements related to food were equal to 36 % of advertisements. In total out of 3,238 advertisements 913 were related to food. Most food advertisements were shown on commercial channels. Unhealthy food was advertised at all times as well as healthy lifestyle. Children are aggressively attacked by food marketing at all time periods. Advertisements that target children should be carefully examined even those that promote healthy lifestyle. Strict regulation is required to protect children from aggressive marketing. 相似文献

目的 为了控制餐饮食品食源性疾病的发生,对餐饮食品原料中沙门菌进行了定量风险评估.方法 采用国家食源性疾病监测网2004年获得的常见9类共10 896份食品中沙门菌污染数据,参考国际食品法典委员和美国农业部建立的即食肉制品中沙门菌致病的剂量-反应关系模型,根据我国居民营养调查数据获得的被评估食品的每日摄入量,对食品污染沙门菌后,人群发生疾病的致病概率进行了评估和预测.结果 评估结果表明,夏秋季节熟肉制品导致沙门菌中毒的致病概率约为0.20,远远高于生肉制品;尽管禽肉的污染水平高于畜肉,但是由于消费量和阳性率的影响,其致病概率为9.11×10-6,低于畜肉(3.14×10-5),均非常低.结论 沙门菌污染食品导致的食源性疾病的发生概率最终取决于食品的膳食消费量和入口前致病菌的繁殖水平,发病率与季节、经济发展水平有明显的相关关系. 相似文献

OBJECTIVE: To study the relationship between foodborne diseases (FBD) and contamination of Salmonella spp. in catering foods, quantitative microbiological risk assessment (QMRA) of Salmonella spp. was used to evaluate the food material or the ready to eat food. METHODS: The contamination data of Salmonella spp. in 10 896 food samples of 9 categories of food which were collected by National Food Contamination and Food Borne Disease Surveillance Net, combining with diet consumption data from National Food Nutrition Survey in 2002, were analyzed by the microbiological risk assessment model developed by WHO/FAO or FDA/FSIS of US to predict probability of FBD. RESULTS: The results of MRA showed that the probability of salmonellosis by consuming ready to eat meat in summer and autumn was 0.20, much higher than the other foods. Although the contamination level in raw poultry was higher than meat, the probability of salmonellosis by raw poultry (9.11 x 10(-6)) was lower than meat (3.14 x 10(-5)) because of the low consumption volume. CONCLUSION: Probability of FBD was significantly correlated with the volume of food consumption, the status of economy and bacteria contamination level. The level of FBD in summer season was higher than in winter and spring because of ambient temperature. 相似文献

Sharp reductions in the wild rabbit (Oryctolagus cuniculus (L.)) population in the Mallee are associated with annual myxomatosis epizootics. The extent to which the population reductions are the direct result of the epizootics varies with time of epizootic occurrence. All grazing animals in the Mallee are under nutritional stress each summer and autumn. When the epizootic occurs during the early summer heavy losses occur in a previously healthy population. Similar losses which occur in the late summer and autumn are the result of a nutritional stress - epizootic complex. The end result in each case is a population reduction of about 80%. This reduction occurs in a population which is the most resistant to myxomatosis known in Victoria and in association with epizootics caused by field strains of myxoma virus of moderate virulence only. The earlier summer epizootics are of considerable economic importance because they sharply reduce the pressure on the limited food available for other grazing animals. 相似文献

探索1种更适合社区使用的伊蚊密度监测新型容器。
2022年8月在上海市闵行区进行第一轮试验,采用人诱法选择 1个绿化面积较大的白纹伊蚊密度较高的小区作为试验场所,根据容器的材质、颜色、孔洞的大小、形状、位置、顶盖颜色等进行随机点位布放65只新的试验容器,连续观察7 d并记录蚊、卵的诱捕结果。2022年9月进行第二轮试验,制作最佳容器后,将140只新型容器与140只传统容器进行对比实验。采用SPSS 22.5软件进行统计分析。
预实验的3类容器布放的第4天(D4)和第7天(D7)诱蚊诱卵的效果有明显变化。一类容器中200 mL杯身上设3个圆形孔洞的容器诱蚊诱卵效果最好,诱蚊/卵阳性率为45.5%(5/11)、其他杯型诱蚊/卵阳性率为12.0%(6/50),两者差异有统计学意义(
新型诱蚊诱卵器可以提高容器有效率、整体回收率、密度精准性,值得进一步探索和研究。
