                              現在很多人都喜歡在空閑的時候買大量的食物囤積在冰箱里。特別是逢年過節的時候,這種情況更是屢見不鮮,肉類是人們常買的食物之一。他們覺得速凍的肉食能保存很長時間,什么時候吃都沒關系。但是,肉類也是有保質期的。下面,就讓小編給大家做個簡單的科普。
                              Nowadays, many people like to buy a lot of food in their spare time and store it in the refrigerator. Especially in the Spring Festival, this situation is common, meat is one of the food people often buy. They think frozen meat can be preserved for a long time, and it doesn't matter when they eat it. But meat also has a shelf life. Now, let's make a simple popular science for you.
                              冷凍肉保質期是多久?
                              How long is the shelf life of frozen meat?
                              根據科普我們可以得知,紅肉:豬、牛、羊等肉類保質期可達10~12個月,其中牛肉性質比豬肉、羊肉穩定,瘦肉又比肥肉保存時間更長一些。禽類:雞、鴨、鵝、鴿等保質期比紅肉類稍短一些,通常為8~10個月。海鮮:魚、蝦、鱉、貝等海鮮由于它們含有大量易于氧化的不飽和脂肪酸,所以保質期比畜禽肉類更短一些,一般能達半年左右,盡量在4個月內食用。如果未經任何處理就冷凍起來,只能保存1—2個月。
                              According to popular science, we can know that the shelf life of red meat: pigs, cattle, sheep and other meat can reach 10-12 months, of which the nature of beef is more stable than pork and mutton, and lean meat is longer than fat meat. Poultry: the shelf life of chicken, duck, goose and pigeon is slightly shorter than that of red meat, usually 8-10 months. Seafood: fish, shrimp, turtle, shellfish and other seafood contain a lot of unsaturated fatty acids which are easy to oxidize, so the shelf life is shorter than that of livestock and poultry meat, which can generally reach about half a year, and should be eaten within 4 months as far as possible. If it is frozen without any treatment, it can only be preserved for 1-2 months.
                              速凍類食品:自制的餃子、包子、湯圓、餛飩等,成分復雜的餡料會逐漸發生口感變化,也很容易串味,因此不宜冷凍太長時間,盡量在一兩個月內吃完。蔬菜:一般蔬菜不宜冷凍,僅少部分蔬菜,如玉米、板栗、豆類等,保質期5個月左右。
                              Quick frozen food: homemade dumplings, steamed buns, dumplings, wonton, etc. the stuffing with complex ingredients will gradually change the taste, and it is easy to cross taste, so it is not suitable to freeze for too long, try to finish it in one or two months. Vegetables: general vegetables should not be frozen, only a small number of vegetables, such as corn, chestnut, beans, etc., shelf life of about 5 months.

                              1. Pretreatment: the internal organs of poultry, seafood and river fresh should be removed, cleaned inside and outside, and then frozen; Other foods and meat also need to be cleaned carefully before freezing to remove bacteria from the surface.
                              2、包裝分袋:所有食品在冷凍前,都應按量分配裝袋,用保鮮袋或保鮮膜仔細包裝,以防3、止水分損失。在外包裝貼上標有日期和名稱的標簽,便于以后取用。
                              2. Packaging: all foods should be packed according to the quantity before freezing, and carefully packed with fresh-keeping bags or plastic film to prevent water loss. Label the outer package with date and name for later use.
                              4、趁早食用:家用冰箱門經常開關、突然斷電等情況,都會使冰箱溫度發生波動。因此,5、從超市購買的各種肉冷凍后盡量在1個月內食用完,現吃現買。
                              4. Eat as early as possible: household refrigerator door often open and close, sudden power failure, etc., will make the refrigerator temperature fluctuations. Therefore, 5. Try to eat all kinds of frozen meat from the supermarket within one month, and buy it now.

                              11、水解:在時間緊的情況下,將包裝袋中的空氣排出,封好開口并用流水沖泡。
                              11. Hydrolysis: in the case of tight time, the air in the packaging bag is discharged, the opening is sealed and the water is used for brewing.
