加拿大的一個組織解釋了為什麽商品大蒜要接受輻射

Health Canada explains food irradiation as, “the process of exposing food to a controlled amount of energy called ‘ionizing radiation’. There are three different types of radiation allowed: Gamma rays, X-rays and electron beam radiation”. This process acts by damaging the food product’s DNA beyond its ability to repair.  Therefore, organisms can no longer successfully continue the process of cell division, and the organism ceases all processes related to maturation or reproduction.

DNA已經被損壞了，所以當然無法正常生長。
