上周投food chemistry X的一篇文章,涉及了食品风味的感官评价。编辑退回了稿件要求提供实施风味研究的许可:The authors should also confirm that their institution has given permission to conduct sensory panel research, however, if permission is not required by your institution, please give a brief statement. 这种应该去找什么机构开呢(已经问了学校的伦理委员会,他们说只能批准动物的),或者开不了许可,声明应该怎么写?
