If you want certain foods to last other than your milk, curd, fruits and vegetable, they need to be kept in the fridge to retain their flavour / freshness.
1. Dried fruit and nuts
Dried fruit and nuts
Like
Most of us just toss dried fruit and nuts in the pantry, but the truth
is that dried fruit and nuts can stay fresh and tasty for longer if you
keep them in the fridge. Storing nuts in a cooler climate will prevent
them from becoming rancid for up to a year, or up to 2 years if you’re
storing them sealed in the freezer. When it comes to dried fruit, it’s
much better to keep them in the fridge because that way they will
maintain their texture in a cool climate for up to six months.
2. Flower bouquets
Who said your fridge is only reserved for groceries? If you’d like to
keep your flower bouquets for a longer time and prevent flower buds from
wilting, store them in the cold overnight. Just make sure that the
flowers don’t touch the fridge shelves or the door because this may
actually have the opposite effect.
3. Avocados
Storing avocados and getting them to stay just ripe enough may seem like
an impossible quest, but it really isn’t. For example, the majority of
people only put avocados in the fridge when they are cut in half, which
is definitely the right thing to do, and we even showed you the best
method to do so in a previous article all about avocados.
However, whole avocados can be easily stored in the fridge as well. If
you have a ripe whole avocado and want to keep it fresh for up to 2
weeks, simply place it in the fridge. However, if you have an unripe
avocado, it’s best to leave it on the counter for a few days and wait
for it to ripen before you place it in the fridge, as cold temperatures
really slow down the ripening process.
4. Ketchup and mustard 
There are two types of people - those who store their condiments in the
pantry, and those who keep them in the fridge. Both of these are right,
but not entirely. While certain condiments, such as hot sauce and
vinegar, for example, can be safely kept in the pantry, doing the same
with ketchup and mustard is not advisable.
The problem isn’t even in them getting spoiled, as the highly acidic
environment and preservatives present in condiments will prevent the
spread of bacteria. The main issue is that warmer temperatures will make
condiments like ketchup and mustard lose their flavor much faster,
which is the last thing you want.
5. Tortillas
A designated bread box is the best way to keep bread and the majority of
other baked goods fresh, the same doesn’t apply to tortillas and other
soft flat-breads. The best way to extend their shelf life for days is to
simply pop them into the fridge after you’ve opened and unsealed a bag.
If eating cold tortillas doesn’t sound so appetizing, though, remember
that you can easily reheat your tortillas on the stove or by microwaving
them on the medium setting for a minute or so.
6. Nail polish
This one might surprise you, but it turns out that there is a
significant number of beauty products, such as eye creams and face masks
that are better off in the fridge. One of the most surprising beauty
items you should start storing in the refrigerator is nail polish.
The reason why is related to sun and light exposure. Sunlight and heat
alter the texture of nail polish over time, making it thick and gloopy
and in some cases, exposure to light and heat can even make it turn into
strange colors. Storing nail polish in the fridge, in turn, will help
preserve the original color and texture of the product.
7. Red wine 
Normally, we are instructed by wine experts to chill white and sparkling
wine before serving, but when it comes to red wine, putting it in the
fridge is considered a big no-no. However, these storage tips and
serving temperature instructions only apply to a full bottle of wine.
When it comes to leftover red wine, storing it at room temperature,
especially in the summer, will make it oxidize, and eventually, it will
taste like vinegar. So, to preserve the beautifully balanced taste of a
good Merlot or Cabernet, for the majority of us who don't have a wine
cellar, it's best to re-cork it and place the bottle in the fridge. If
you prefer your red wine at room temperature, simply take it out of the
fridge 15-20 minutes before serving, of course.
