什么食物不應該冷藏?

Most homes these days have refrigerators and have a habit of storing all the food in it. However, in fact, not all foods are suitable for storage in the refrigerator, not to mention that each food has a different way of preservation.

現(xiàn)在大多數(shù)家庭都有冰箱，并且有把所有食物都放在冰箱里的習慣。然而，事實上，并不是所有的食物都適合放在冰箱里儲存，更不用說每種食物都有不同的保存方法。

If we do not know how to properly preserve, some foods, when stored in the refrigerator, can lose their nutrition and even be poisonous, easily affecting health. Here are 7 foods that sisters should never store in the refrigerator.

如果我們不知道如何妥善保存，有些食物在儲存在冰箱里時，會失去營養(yǎng)，甚至有毒，容易影響健康。下面是姐妹們不應該放在冰箱里的7種食物。

Food should not be refrigerated

不應該冷藏的食物

1. Potatoes

土豆

According to the US Food Standards Agency (FSA), potatoes are foods you should never keep in the refrigerator - as they can be harmful.

根據(jù)美國食品標準局(FSA)的說法，土豆是絕對不應該放在冰箱里的食物，因為它們可能有害。

“The most important food that should not be refrigerated is potatoes,” explains the FSA's website. When they are stored in the refrigerator, the starch in potatoes is converted to sugar. When baked or fried, these sugars combine with the amino acid asparagine and create the chemical acrylamide, which is believed to be harmful to health.

“最重要的不應該冷藏的食物是土豆，”食品標準局的網(wǎng)站上解釋道。當土豆被儲存在冰箱里時，土豆中的淀粉會轉(zhuǎn)化為糖。當烘焙或油炸時，這些糖與氨基酸天門冬酰胺結(jié)合，產(chǎn)生化學物質(zhì)丙烯酰胺，這被認為是對健康有害的。

2. Watermelon

西瓜

In the summer, many people like to eat melons in the refrigerator because it will be cooler. However, everyone should know that melons contain many natural antioxidants that are good for health, can prevent cancer or many other problems.

夏天的時候，很多人喜歡在冰箱里放西瓜，因為這樣比較涼快。然而，每個人都應該知道，西瓜含有許多對健康有益的天然抗氧化劑，可以預防癌癥或許多其他問題。

Watermelon, for example, contains several antioxidants such as lycopene and beta-carotene. But these are lost when we put the watermelon in the refrigerator. Therefore, if cut watermelon, you should wrap it with food wrap to limit the loss of nutrients.

例如，西瓜含有多種抗氧化劑，如番茄紅素和-胡蘿卜素。但是當我們把西瓜放在冰箱里的時候，這些都丟失了。因此，如果切西瓜，你應該用食品包裝紙把它包起來，以限制營養(yǎng)流失。

3. Garlic

大蒜

Many people have the habit of leaving garlic in the refrigerator without knowing this will cause the garlic to spoil at a faster rate by adding moisture, unless the garlic is peeled and prepared. It is best to keep the garlic in a dry place, with good air circulation, at room temperature and away from light. Garlic will also last longer if left intact until you're ready to use it.

很多人都有把大蒜放在冰箱里的習慣，卻不知道這樣做會增加水分，讓大蒜腐爛得更快，除非大蒜是剝皮和準備好的。最好將大蒜保存在干燥、空氣流通良好的地方，室溫下遠離光線。大蒜如果保存完好，保存時間也會更長，直到你準備使用它。

4. Tomatoes

西紅柿

Many people like to refrigerate tomatoes because they think it will be crunchier and cooler when added to salads. However this is not recommended. Keeping tomatoes at temperatures below 12 degrees C will affect the nutrients of this fruit, damage the inner membrane of the fruit, alter the taste and texture.

許多人喜歡把西紅柿放在冰箱里，因為他們認為把它加到沙拉里會更脆更涼。但是不建議這樣做。將番茄的溫度保持在12攝氏度以下會影響這種水果的營養(yǎng)成分，破壞水果的內(nèi)膜，改變它的味道和口感。

Cold temperatures alter the natural texture, hindering the production of volatile compounds found in tomatoes. 65% of these compounds will disappear if refrigerated.

低溫會改變番茄的天然質(zhì)地，阻礙番茄中揮發(fā)性化合物的產(chǎn)生。如果冷藏，這些化合物中的65%將消失。

Tomatoes will lose their flavor and may taste slightly watery and underripe. Many studies have shown that tomatoes stored in the natural environment have a much better taste than those stored in the refrigerator.

西紅柿會失去它們的味道，嘗起來可能有點水和未成熟。許多研究表明，在自然環(huán)境中儲存的西紅柿比在冰箱中儲存的味道更好。

5. Eggs

雞蛋

According to a study published in the Journal of Food Protection, eggs when stored at extremely low temperatures, their nutritional value decreases.

根據(jù)發(fā)表在《食品保護雜志》上的一項研究，雞蛋在極低溫下儲存時，其營養(yǎng)價值會下降。

The essential minerals and enzymes found in eggs can lose their effects on human health when eggs are stored in the refrigerator because cold temperatures can destroy the active enzymes. What's more, this study also found that eggs stored in the refrigerator had a higher risk of becoming contaminated with salmonella.

當雞蛋被儲存在冰箱中時，雞蛋中所含的必需礦物質(zhì)和酶會失去對人體健康的影響，因為低溫會破壞活性酶。更重要的是，這項研究還發(fā)現(xiàn)，儲存在冰箱中的雞蛋被沙門氏菌污染的風險更高。

Salmonella is a type of bacteria that can cause infections like stomach ailments and typhoid fever. So it is better to keep eggs out of the refrigerator and use them quickly so they don't spoil.

沙門氏菌是一種可以引起胃病和傷寒等感染的細菌。所以最好不要把雞蛋放在冰箱里，而且要快用，這樣才不會變質(zhì)。

6. Herbs

草本植物

Herbs and basil are tropical plants that cannot tolerate cold. Therefore, during storage should limit to the refrigerator but should store at indoor temperature.

草本植物和羅勒是不能耐寒的熱帶植物。因此，儲存期間應限制放在冰箱，應在室內(nèi)溫度下儲存。

7. Onions

洋蔥

The whole onion is best kept in a dark and cool place. They contain starch, so they will be damp, soaked in water and easily damaged if stored in the refrigerator for too long. Once cut, onions should be sealed in a can and kept in the refrigerator.

整個洋蔥最好保存在陰涼處。它們含有淀粉，所以如果在冰箱里存放太久，會受潮，浸在水里，很容易損壞。洋蔥切好以后，應該密封在罐頭里，放在冰箱里。
