商品簡介 |
Canning includes handling food in shut glass jars at high temperatures. The intensity hinders regular decay by annihilating food impurities and, simultaneously, eliminates air from the jars. As the jars cool, a vacuum seal structures to forestall repeated pollution. Canning was once a strict lifeline a long time before refrigeration when it was important to safeguard food to take care of families through the long cold weather months. |
