外层黑的没关系,是氧化所致。问题你这里面都有黑的,明显就是昨天没卖完混在一起再包装的。以前听过超市都这么干。没有异味没关系的
当然可以啊!如果不打开怎么知道有问题?我上次买了几个罐头,打开后才发现过期,马上去退。英文搜索了一下,说颜色不代表变质,还说“完全正常”,关键是味道和粘度不可疑就没问题。
话说~~打开包装了 还能退?
- It generally starts browning or graying from the inside. This is because there's no oxygen getting through to the core, starting the myoglobin on it's pigment-creating journey. It's not uncommon to buy meat from the store, open it right up, and find brown on the inside. It's a totally normal process.
- Again, "safe" here meaning that it's not rotten. If it has E. coli, it'll have E. Coli whether it's fresh or not.
