怎么保鲜葡萄

葡萄富含有益于人体身心健康的多种元素,如维生素C、抗氧化剂,及其它多种维生素。多食用新鲜的葡萄,还有益于提高认知能力,改善视力和降低高血压。[1] 保鲜葡萄的方法有很多,下面就介绍几种。

部分 1 部分 1 的 3:

挑选新鲜的葡萄

  1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/0\/06\/Keep-Grapes-Fresh-Step-1.jpg\/v4-460px-Keep-Grapes-Fresh-Step-1.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/0\/06\/Keep-Grapes-Fresh-Step-1.jpg\/v4-728px-Keep-Grapes-Fresh-Step-1.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 挑选绿皮且紧致的葡萄。皮呈红色且与果肉分离的葡萄,通常已经非常成熟,买回家后不能存放太久。
  2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/1\/1a\/Keep-Grapes-Fresh-Step-2.jpg\/v4-460px-Keep-Grapes-Fresh-Step-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/1\/1a\/Keep-Grapes-Fresh-Step-2.jpg\/v4-728px-Keep-Grapes-Fresh-Step-2.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 观察葡萄的颜色,以辨别成熟度。通常绿色的葡萄应该发出亮亮的光泽,而红色或紫色的葡萄则发出较暗沉的光泽。[2]
    • 不要购买颜色看起来怪怪的葡萄,很可能内部已经开始腐烂了。
  3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/d\/da\/Keep-Grapes-Fresh-Step-3.jpg\/v4-460px-Keep-Grapes-Fresh-Step-3.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/d\/da\/Keep-Grapes-Fresh-Step-3.jpg\/v4-728px-Keep-Grapes-Fresh-Step-3.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 闻闻葡萄的香味。如果闻起来有股酸味,那么葡萄已经开始腐烂了。
  4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/0\/0a\/Keep-Grapes-Fresh-Step-4.jpg\/v4-460px-Keep-Grapes-Fresh-Step-4.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/0\/0a\/Keep-Grapes-Fresh-Step-4.jpg\/v4-728px-Keep-Grapes-Fresh-Step-4.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 观察葡萄茎。如果茎很软,而且出现白色或灰色的斑点,那么不要挑选这串。因为出现灰白斑点的葡萄茎,往往预示着葡萄将会很快腐烂。

合理保存葡萄

  1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/f\/f8\/Keep-Grapes-Fresh-Step-5.jpg\/v4-460px-Keep-Grapes-Fresh-Step-5.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/f\/f8\/Keep-Grapes-Fresh-Step-5.jpg\/v4-728px-Keep-Grapes-Fresh-Step-5.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 一到家就把葡萄放进冰箱里。最好置于30~32华氏度(-1~0摄氏度)下。
  2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/95\/Keep-Grapes-Fresh-Step-6.jpg\/v4-460px-Keep-Grapes-Fresh-Step-6.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/95\/Keep-Grapes-Fresh-Step-6.jpg\/v4-728px-Keep-Grapes-Fresh-Step-6.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 不要清洗葡萄,直接将其放进密封的塑料袋或罐子里。清洗葡萄会加速腐烂,通常清洗过后的葡萄最多只能存放七天。
    • 如果你立马想冷冻葡萄,那么可以清洗。清洗过后,先将葡萄平铺在做饼干的吸水纸上,这样可以防止在冷冻的过程中粘连在一起。冷冻好后,再把它们装进密封罐里。[3]
  3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/7\/76\/Keep-Grapes-Fresh-Step-7.jpg\/v4-460px-Keep-Grapes-Fresh-Step-7.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/7\/76\/Keep-Grapes-Fresh-Step-7.jpg\/v4-728px-Keep-Grapes-Fresh-Step-7.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 将葡萄放在冰箱的里层。通常,冰箱的里层较外面更冷,可以将葡萄保存至2~3星期。
  4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/a4\/Keep-Grapes-Fresh-Step-8.jpg\/v4-460px-Keep-Grapes-Fresh-Step-8.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/a4\/Keep-Grapes-Fresh-Step-8.jpg\/v4-728px-Keep-Grapes-Fresh-Step-8.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 将整串的葡萄分成几小串。这样,存放的时候不会叠在一起,也就不易腐烂。
  5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/ad\/Keep-Grapes-Fresh-Step-9.jpg\/v4-460px-Keep-Grapes-Fresh-Step-9.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/ad\/Keep-Grapes-Fresh-Step-9.jpg\/v4-728px-Keep-Grapes-Fresh-Step-9.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 不要将葡萄跟有味道的食物摆放一起,如洋葱、韭菜等等。因为葡萄善于吸收气味,如果摆放在有味道的食物旁边,葡萄就会吸收它们的气味,到时候会很难吃。

解冻葡萄供食用

  1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/e\/ed\/Keep-Grapes-Fresh-Step-10.jpg\/v4-460px-Keep-Grapes-Fresh-Step-10.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/e\/ed\/Keep-Grapes-Fresh-Step-10.jpg\/v4-728px-Keep-Grapes-Fresh-Step-10.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 在食用葡萄前,先清洗葡萄。用水可以洗掉葡萄表面的细菌和其它有害物质。
  2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/e\/e4\/Keep-Grapes-Fresh-Step-11.jpg\/v4-460px-Keep-Grapes-Fresh-Step-11.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/e\/e4\/Keep-Grapes-Fresh-Step-11.jpg\/v4-728px-Keep-Grapes-Fresh-Step-11.jpg","smallWidth":460,"smallHeight":306,"bigWidth":728,"bigHeight":485,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 从冰箱取出葡萄后的72小时内,要把葡萄吃完。从冰箱取出的72小时内,葡萄会开始脱水起皱,慢慢丧失营养成分。[4]

小提示

  • 如果想在午餐时吃点冷冻的葡萄,最好在打包午餐前就开始把葡萄拿出里,放在室温下解冻。这样,在你吃午餐的时候,葡萄吃起来就会既冰爽又新鲜了。

警告

  • 从树下采摘下来之后,葡萄就开始腐烂的过程了。所以一旦摘下,就把它放在冰箱里冷藏或冷冻,等吃之前再拿出里解冻,这样不至于烂掉。
