But before you can throw it away, your mother stops you. She cuts off the mouldy part and eats the rest. Is it safe to do this? Mould can grow on almost all kinds of foods.Mould is usually green, white, black or grey. Mould makes food soft and changes its colour.Mouldy food tastes quite bad and it's not safe to eat. If you find mould in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually holds water. This makes it easy for mould to grow below its surface(表面). Bacteria (细菌) can also grow along with it. But it's easy to remove mould from hard food. Mould can't grow very far inside this kind of food. According to the research, you should cut off about 2. 5 cm around and below the mold to remove it. It's OK to cut off the mouldy parts from hard food and eat the rest. But if the food is totally covered with mould, you should still throw it away. Most kinds of mould are bad for us. But some kinds of mould can be used to make food. For example, penicillium(青霉菌) can be used to make many kinds of cheeses, such as blue cheese. These cheeses are safe to eat and they're quite delicious as well. ( )1.
