生活在大都市的我们，吃不到最新鲜的菜。为了节省时间，通常会一次购买几天的量（尤其是水果）。如果不注意保鲜，时间稍放得久一点，不仅给微生物的生长提供了很好的条件，自身的物质也会分崩离析。为了能延缓食物变老，防止微生物对他们的损害，能吃到更加安全新鲜的产品，小编告诉您几类常见的保鲜方法。
Living in a big city, we can't eat the most fresh food. In order to save time, usually buy a few days a few days (especially fruit). If you do not pay attention to the preservation time, slightly put a little too long, not only for microbial growth and provide a very good condition, the material will fall apart. In order to delay the aging of the food, prevent the damage to them, can eat more safe and fresh products, small make up to tell you a few kinds of common preservation method.
1、保鲜期特别短，可能在一天内腐败的，应用降温法。如荔枝，一盆水大约加10克的食盐，泡一会然后晾干，放入水果音乐保鲜袋中，放入零下冷冻层，然后拿出来，常温下自然解冻。荔枝保鲜其实不应该放在保鲜柜，提醒大家。最好是放在冷冻层以零下的温度来保存，取出后让其自然解冻，因为只有这样荔枝的色、香、味才能得到有效保留;
1, the fresh period is very short, may be in a day of corruption, the application of cooling method. Such as litchi, a pot of water, about 10 grams of salt, soak for a while and then dry, put the fruit music in the bag, put into the frozen layer, and then take out, natural thawing at room temperature. Litchi preservation should not be placed in the storage cabinet, to remind everyone. It is best to put in the frozen layer to the temperature below zero to save, remove and let the natural thaw, because only the color, smell and taste of litchi can be effectively preserved;
2、表皮很厚的，应用保鲜袋保险法。如西瓜，只要拿保鲜膜把西瓜表面覆起来就可以了，其实西瓜只是这样保鲜是不对的，因为放入蛋糕柜的西瓜，看上去其实非常容易。但其实熟食柜会从西瓜表皮吸干水分，这样即使包着保鲜膜覆盖的也没用，所以西瓜保鲜应该用保鲜膜全部包起来，连皮一起包在保鲜膜内。然后把空气挤出;
2, the skin is very thick, the use of plastic bags insurance law. Such as watermelon, as long as the preservation film to cover the surface of the watermelon can be, in fact, only this is not a fresh watermelon, because the watermelon into the cabinet, it looks very easy. But in fact the delicatessen will moisture from watermelon epidermal dry, so even if wrapped in plastic wrap cover is useless, so fresh watermelon should use plastic wrap all wrapped up, together with skin wrapped in cling film. And then the air out;
3、与空气接触，很容易烂的水果，应用阴凉加保鲜袋保险法。如香蕉，香蕉的正确方法应该是将香蕉放入水果保鲜袋。放入阴凉地方保存即可。这里人气美食提醒大家，千万不要将香蕉放入冷柜。
3, contact with the air, it is easy to rotten fruit, the application of a cool and fresh bags of insurance law. Such as bananas, the correct way of bananas should be put into the fruit preservation bag of bananas. Store in a cool place. This popular delicacy to remind you, do not be a banana into the freezer.
对于水果来说，保鲜主要需要注意三个方面：其一，尽量抑制呼吸作用，减少内部营养的损失，比如低温或者加二氧化碳；其二，抑制细菌的生长，防止腐烂，比如使用抑菌剂；其三，控制蒸腾作用，减少水分损失，保持一定的湿度，保留新鲜的状态。
For the fruit, fresh need to pay attention to three aspects: first, to inhibit respiration, reduce internal nutrient losses, such as low temperature or addition of carbon dioxide; second, to prevent the decay of growth inhibition of bacteria, such as the use of antibacterial agents; third, control of transpiration, reduce water loss, maintain a certain humidity, keep fresh state.
