點解整生果片要用風乾機,而唔會用焗爐低溫焗呢?
另外,有冇人個維他命係幾多度會被破壞呢?

Dried fruits contain no water-soluble vitamins (such as the B vitamins or Vitamin C) because these vitamins are destroyed when the fruit is dried. If any packaged dried fruits you eat have a high Vitamin C content on the nutrition label, the vitamin has most likely been added back after processing. |
