Anthocyanins are important components in the peel of red pears and contribute to the appearance of the fruit.Melatonin application is known to affect anthocyanin biosynthesis,but the effect of preharvest melatonin application on fruit coloration remains l
中国对于水产品的需求量日益增加,由于水生生物具有很强的重金属富集能力,因此水生生物的重金属富集及人群有关的相关风险评价日益受到人们的关注。本研究对目前国内外相关学者的研究进行总结与分析,讨论了水生生物的重金属污染研究现状、富集及暴露评价等内容,强调了建立地区性的水生生物重金属富集与暴露风险评价的重要性。本研究可为后续水生经济生物对人体健康的风险评价和生态环境保护等方面的相关研究提供更为细致的理论支持,也可为消费者提供更完善的风险评估结果和消费建议。

水产品作为与畜禽肉类具有同等食物地位的动物性食物,具有高蛋白、低脂肪和低热量的特征,在居民食物结构中发挥着重要作用。为研究水产品对动物性食物蛋白质总量的贡献水平,本研究对中国动物性水产品可食率和蛋白质贡献量进行了测算,并与畜禽肉类、蛋奶类等动物性蛋白质贡献量进行比较分析,测算得出水产品整体及各品类水产品的平均可食率、平均蛋白质含量和蛋白质贡献率等相关指标。水产品平均可食率为54.30%,其中,海水产品平均可食率为51.86%,淡水产品平均可食率为56.67%。每100 g水产品可食部的蛋白质含量为16.8
