Which food can not be put in the refridgerator?Answer it ,please.
火龙果、芒果、荔枝、龙眼、木瓜、红毛丹、香蕉等都非常畅销.可是,这些水果买回家后一旦放进冰箱,没几天就开始出现黑斑,它们大部分比较怕冷,不适宜放在冰箱中冷藏.果皮发生凹陷,出现一些黑褐色的斑点,就说明水果被冻伤了.冻伤的水果不仅营养成分遭到破坏,还很容易变质.再过几天,果肉的颜色就会变成褐色,并开始腐烂,这样的水果往往不能再吃.
热带水果最好放在避光、阴凉的地方贮藏,如果一定要放入冰箱,应置于温度较高的蔬果槽中,保存的时间最好不要超过两天.有些买回来时还未成熟的热带水果,比如颜色发青的香蕉等,耐寒性更差,因此最好别放入冰箱中菜冰箱储藏诀窍.绿叶菜很容易打蔫,要让它保持新鲜,放冰箱的确是一种办法,但是冰箱温度最好控制在0－4摄氏度之间,外面再套个保鲜袋,或者放进保鲜盒储藏,才能达到保鲜效果.记得储藏前最好不要清洗,放置时间不宜太长,否则菜很容易捂烂.
像土豆、黄瓜、胡萝卜等块茎类蔬菜没有那么娇气,室温下保存就可以了,不需要放冰箱.需要注意的是,西红柿不适合放入冰箱贮藏.因为西红柿经低温冷冻后,肉质就会呈水泡状,鲜味会消失,不容易煮熟,严重的还会酸败腐烂.
还有不少水果也不适合放冰箱储藏,尤其是芒果、柿子、香蕉等酱果类的水果.所谓酱果类水果就是那些能够剥皮、果肉呈酱状的水果,浆果类水果在低温条件下,香味会减退,表皮也会变质.比如说,我们都知道香蕉放在12℃以下容易发黑腐烂,还有鲜荔枝在0℃的环境中放置一天,果皮会变黑、果肉会变味.像橙子、柠檬、桔子等柑橘类的水果,在低温情况下,表皮的油脂很容易渗进果肉,果肉就容易发苦,所以也不适宜放冰箱,柑橘类水果最好放置在15度左右的室温下储藏.像草莓、杨梅、桑椹等即食类水果,最好即买即食,放入冰箱不仅会影响口味,也容易霉变.苹果、西瓜则可以短期暂住冰箱,延长保质期.
白菜、芹菜、洋葱、胡萝卜等的适宜存放温度为0℃左右.
黄瓜、茄子、西红柿等的适宜存放温度为7．2℃至10℃之间.
南瓜适宜在10℃以上存放.
西红柿西红柿经低温冷冻后,肉质呈水泡状,显得软烂,或出现散裂现象,表面有黑斑,煮不熟,无鲜味,严重的则腐烂.
香蕉若把香蕉放在12℃以下的地方贮存,会使香蕉发黑腐烂.
鲜荔枝若将荔枝在0℃的环境中放置一天,即会使其表皮变黑,果肉变味.
巧克力巧克力在冰箱中冷藏后,一旦取出,在室温条件下即会在表面结出一层白霜,极易发霉变质,失去原味.
火腿若将火腿放入冰箱低温贮存,其中的水分就会结冰,脂肪析出,火腿肉结块或松散,肉质变味,极易腐败.
面包在烘烤过程中,面粉中的直链淀粉部分已经老化,这就是面包产生弹性和柔软结构的原因.随着防止实践的演唱,面包中的直链淀粉部分的直链慢慢缔合,而使柔软的面包逐渐变硬,社中现象叫做“变陈”.变陈的速度与温度有关.在低温室变硬较快,面包放在冰箱中药比放在室温变硬的速度来的快,所以,如果短时间存放应将面包放在室温下,防止面包变硬.
中药不宜放在冰箱里,药材放入冰箱内,和其他食物混放时间一长,不但各种细菌容易侵入药材内,而且容易受潮,破坏了药材的药性,所以对一些贵重的药材,如人参、鹿茸、天麻、党参等,若需长期保存,可放在一个干净的玻璃瓶内,然后投入适量用文火炒至暗黄的糯米,待晾凉后放入,将瓶盖封严,搁置在阴凉通风处.
吃剩的月饼别放进冰箱,月饼是用面粉、油、糖和果仁等配料精制, 并经过焙烤的糕点.焙烤食品是不宜放入冰箱储存的. 尽管对于有些品种的月饼来说,放入冰箱可以延长其保质时间,但还是会影响其风味.这是因为,月饼原料中的淀粉在经过焙烤后熟化,并变得柔软,而在低温的条件下,熟化了的淀粉会析出水分,变得老化（也就是“返生”）,使月饼变硬、口感变差.
含油脂、水分较少的月饼品种,比如老北京的自来红、自来白月饼,变硬现象更为明显,把它放在冰箱低温潮湿的环境中,不但会很快变硬,还容易发霉.但对广式月饼来说,其油脂含量高、面粉少,口味变化会相对小些.
冰箱中的鱼不宜存放太久,家用电冰箱的冷藏温度一般为－15℃,最佳冰箱也只能达到－20℃,而水产品,尤其是鱼类,在贮藏温度未达到－30℃以下时,鱼体组织就会发生脱水或其它变化,如鲫鱼长时间冷藏,就容易出现鱼体酸败,肉质发生变化,不可食用.因此,冰箱中存放的鱼,时间不宜太久.
冷冻食品解冻后不宜再存放,从市场上买回来的冷冻食品,肉、鱼、鸡、鸭、蛋、速冻蔬菜等,一经解冻要尽快加工食用,不宜存放.如果存放时间太长,肉、鱼、鸡,鸭等会因为细菌和酶的活力恢复,不但能很快繁殖分解蛋白质引起变质,而且还能产生有毒的组胺物质,人吃了会引起食物中毒；冷冻蔬菜存放时间太长,不仅色变,营养损失,品质下降,而且也很容易腐烂变质,不能食用.冷冻的肉、鱼、鸡、鸭等冷冻时由于水分结晶的作用,其组织细胞便受到破坏,一经解冻,被破坏了的组织细胞中,会渗出大量的蛋白质,就成了细菌繁殖的养料.有实验表明,将经冷冻1天的新鲜青花鱼,放在30℃温度下6小时,其腐败速度要比鲜鱼快1倍；将解冻的蛋黄放在18℃温度下2小时,细菌数增加约2倍,经8小时,细菌数增加50倍以上；将冷冻的鲜鸡蛋,放在0～15℃温度下达10天以上,因经冷、热温度的变化时间太长,不但卵膜变松、蛋清稀薄,而且还发生粘壳、散黄,甚至霉变、发臭,不能食用；冷冻过的蔬菜,尤其是在热天更不宜存放,否则绿叶蔬菜很快会变黄,维生素C也易被破坏.蔬菜放在20℃温度下,比放在6～8℃的温度下,维生素C的分解损失要多2倍.
黄瓜青椒：黄瓜、青椒在冰箱中久存,会出现冻“伤”——变黑、变软、变味.黄瓜还会长毛发粘.因为冰箱里存放的温度一般为4℃至6℃左右,而黄瓜贮存适宜温度为10℃至12℃,青椒为7℃至8℃.故不宜久存.
鲜果汁,冷冻后容易破坏它的维生素等营养成分

bananas, oranges

apple、banana、tomato
