生活在大都市的我們，吃不到最新鮮的菜。為了節省時間，通常會一次購買幾天的量（尤其是水果）。如果不注意保鮮，時間稍放得久一點，不僅給微生物的生長提供了很好的條件，自身的物質也會分崩離析。為了能延緩食物變老，防止微生物對他們的損害，能吃到更加安全新鮮的產品，小編告訴您幾類常見的保鮮方法。
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、保鮮期特別短，可能在一天內腐敗的，應用降溫法。如荔枝，一盆水大約加10克的食鹽，泡一會然后晾干，放入水果音樂保鮮袋中，放入零下冷凍層，然后拿出來，常溫下自然解凍。荔枝保鮮其實不應該放在保鮮柜，提醒大家。最好是放在冷凍層以零下的溫度來保存，取出后讓其自然解凍，因為只有這樣荔枝的色、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，應用保鮮袋保險法。如西瓜，只要拿保鮮膜把西瓜表面覆起來就可以了，其實西瓜只是這樣保鮮是不對的，因為放入蛋糕柜的西瓜，看上去其實非常容易。但其實熟食柜會從西瓜表皮吸干水分，這樣即使包著保鮮膜覆蓋的也沒用，所以西瓜保鮮應該用保鮮膜全部包起來，連皮一起包在保鮮膜內。然后把空氣擠出;
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、與空氣接觸，很容易爛的水果，應用陰涼加保鮮袋保險法。如香蕉，香蕉的正確方法應該是將香蕉放入水果保鮮袋。放入陰涼地方保存即可。這里人氣美食提醒大家，千萬不要將香蕉放入冷柜。
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.
對于水果來說，保鮮主要需要注意三個方面：其一，盡量抑制呼吸作用，減少內部營養的損失，比如低溫或者加二氧化碳；其二，抑制細菌的生長，防止腐爛，比如使用抑菌劑；其三，控制蒸騰作用，減少水分損失，保持一定的濕度，保留新鮮的狀態。
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.
