说到食物,消费者的口味可能各不相同,但他们看重的品质是不变的. 新鲜, high-quality ingredients, 方便和环境责任始终是消费者对食品和包装的首要要求. 罐头可以帮助品牌实现所有这些,但许多消费者没有意识到这一事实.

1810年,英国国王乔治二世授予彼得·杜兰德(Peter Durand)用密封锡容器保存食物的想法专利,此后金属食品包装一直保持着食物的新鲜. By the end of the 20th century, 水果罐头, 蔬菜, 肉类和食物已经成为我们文化的一个标准部分,几乎在每个家庭的食品储藏室都能找到.

今天, 然而, while we continue to value canned foods for the convenience they offer, 我们往往忘记了最初促使杜兰德这样的人用金属包装食品的好处, namely the health and nutritional advantages that the format affords. 一些消费者认为罐头食品不如新鲜或冷冻食品有营养. But, these canned food facts prove that nothing could be further from the truth. Canned foods are nutritionally on par with fresh and frozen products, 在很多情况下, they are more nutritious. 例如,罐装番茄通常比新鲜番茄含有更多的番茄红素和-胡萝卜素. Canning also helps make fiber in certain 蔬菜, 像豆子, more soluble and therefore more useful to the human body. 

罐装设备战略性地设置在农场附近,这样水果和蔬菜在采摘后的几个小时内就能被罐装——这是它们最新鲜的时候. The food is then cooked in the can to destroy bacteria, 在罐头的整个保质期内,在低氧环境中保持食品罐装当天的维生素和营养成分的相同数量,而不需要任何化学防腐剂. 

这是 an important distinction between canned and fresh foods. 水果和蔬菜从被采摘的那一刻起就开始失去营养价值,因此在农场附近设置罐装和冷冻设备. 它可以, 然而, sometimes take weeks to transport fresh produce from the farm to store shelves, during which many of the valuable nutrients can be lost. 结果是, 新鲜食品通常在采摘后用防腐剂处理,以防止变质,但也使消费者接触到不必要的化学物质. 当谈到冷冻食品时,农产品会立即快速冷冻以保持新鲜. 然而, 然后,在储存和运输过程中,各品牌将面临高昂的能源成本,以保持蔬菜处于冷冻状态. Goods in steel food cans avoid this problem since they can be transported as-is.

The Value of Metal 食品包装

The high temperatures of retort cooking effectively sterilize the food in cans, which is critical to maintaining the safety of those products. 金属罐在热处理和储存过程中保护食品免受任何外部影响,因为在还原之前形成了密封. According to the Center for Disease Control, 至少128个,000 Americans are hospitalized each year with food-borne illnesses, 分析得出的结论是,罐装食品是更安全的选择,部分原因是罐装过程为微生物污染创造了屏障. In fact, according to U.S. 食物 & Drug Administration records, 在超过35年的时间里,没有发生过因金属包装失效而导致食源性疾病的事件. 

由于金属食品包装在蒸煮过程中比其他材料更快地将热量传递给食品,并使热量完全渗透到产品的中心, 食物完全煮熟并保存,在储存过程中没有变质的风险. 这是 essentially the exact same process used in home canning, simply on a larger scale—the food, water and any salt or spices for taste are canned, 加热, 然后静待冷却. No further additives, preservatives or chemicals are needed. 

Canned foods provide a smart, shelf-stable option for families and one that offers valuable savings, 既减少了准备一顿饭所需的时间,又帮助家庭在预算紧张的情况下保持健康的生活方式. 

And once the packaging process is complete, 只有金属罐才能最有效地继续保持它所装食物的质量. 食物s typically degrade through extended exposure to air or sunlight, 金属是唯一一种完全防止光和氧气渗入包装的容器材料, offering excellent barrier properties. 这是, 当然, 为什么从炼乳到宠物食品等产品传统上都是用金属包装的, 作为屏障,可以最好地保护并大大延长产品的保质期.
