美国专利及商标局-
多年来，美国专利及商标局搜集了各种使肉质鲜嫩的技术，从传统手艺（敲击，酶嫩化剂）到创新技术（使用压力脉冲或声波让肉均匀变化）应有尽有。
Over the years , the U.S. Patent and Trademark Office has rounded up herds of ideas for tenderizing meat , from the familiar ( spiky hammers , enzymatic tenderizers ) to the outlandish ( using pressure pulses or acoustic waves on submerged meat ) .
