天然植物提取物含有多种抗氧化剂成分，这些抗氧化剂可以抑制肉类加工过程中HAs的生成。然而肉类中HAs的生成还会受到原料肉基质的影响，在特定基质的肉制品中不同种类多酚对HAs的抑制作用不同。目前，大多数研究集中于酚类化合物对牛肉、猪肉和鸡肉等原料肉中HAs形成的影响，而关于酚类物质对番鸭肉制品中游离和结合态HAs抑制作用的报道较少。南京农业大学Yan Xu等在桑叶提取物酚类成分鉴定的基础上，筛选出来...
To manage atmospheric carbon dioxide and convert the gas into a useful product, Cornell scientists have dusted off an archaic – now 120 years old – electrochemical equation. The group aims to thwart t...
By bringing together the right materials duking it out, a Cornell-led collaboration has for the first time used voltage to turn on and off a material’s crystal symmetry, thereby controlling its electr...
