Follow these tips to get the most mileage out of your grocery budget.

When we shop, we never buy anything with the intention of throwing it away. 

Still, there are times when the food destined for our stomachs winds up in the bin. Sometimes it's an oversight, but it can also come down to a profound confusion about the best way to keep food for optimal longevity. 

Limp herbs, furry bread and curdled milk are all commonplace in the home kitchen and although deterioration is inevitable, there are ways we can delay the decay of our more fragile groceries.

If you're in the dark about storing food to keep it fresher for longer, here are some mistakes to avoid if you want to make the most of your grocery shop. 

1. Not making the most of your freezer

Yes, your fridge keeps most things fresh, but your freezer can keep some items fresher for much, much longer. Of course, we all know about freezing meat and fruit such as bananas, but did you know nuts are also suitable for freezing? 

"Nuts are expensive and can go rancid quickly once opened, but they're perfect for freezing," says CHOICE kitchen expert Fiona Mair

She suggests storing nuts in an airtight container and using them straight from the freezer as needed. Fiona also reveals that seeds such as fennel, poppy and sesame can be stored and used in the same way.

2. Refrigerating your bread

If this is your habit, it's time to break it. Bread and moisture are not great friends and you'll find your loaf becomes stale much quicker than if you leave it at room temperature. 

Also, avoid keeping your bread in a plastic bag, as this will encourage mould, especially in humid climates. Instead, keep it in a paper bag, or, if you live somewhere particularly humid, slice your bread and store it in the freezer. 

Of course, every loaf is destined eventually to go stale. But rather than tossing it, whizz it in a food processor and freeze the crumbs for making schnitzels.

Setting your fridge and freezer to the wrong temperatures can be fatal to keeping food fresh.

3. Setting your fridge to the wrong temperature

Fix that stat! Food will spoil at a greater rate if your fridge is set to the wrong temperature. 

Too cold and you'll be finding frost-bitten food shivering in the depths of the fridge. Too warm and bacteria could proliferate, creating a food poisoning risk. 

Some fruit and veg with a high water content, such as cucumbers and lettuce, are prone to freezing below 0°C and become a gelatinous mess once defrosted.

But other foods such as meat and fish prefer temperatures below 0°C, and these should be stored in the chiller compartment. If you're unsure what temperature is best, CHOICE fridge expert Ashley Iredale says to set it to 3°C. 

"The Australian Standard for fridges uses a fresh food compartment average temperature of 3°C," he says. "It's a good target to aim for because it means not freezing foods yet still keeping them below 4°C."

4. Being disorganised

We've all had the unpleasant experience of discovering last month's curry skulking in the back of the fridge. But there are also a couple of other reasons why a neat fridge is a good fridge. 

First, if it's overloaded with food, finding things is like a scavenger hunt and leaving the door open while you locate the mayo wastes energy and money. 

Second, if you let the air circulate within the fridge, it will do its job much better. And of course, keeping it lightly stocked will hopefully mean you don't forget about that tzatziki you bought last week.

5. Not knowing the difference between use-by and best-before

Some of us have a cavalier attitude towards vaguely whiffy items and others adhere strictly to best-before dates. 

But did you know that use-by and best-before are not the same thing? You should definitely heed use-by dates, as these products need to be eaten by a specified day – but best-before dates are different. 

"Foods with a best-before date are less perishable, and this date gives a guide as to how long you can expect the food to keep its quality, rather than its safety," says CHOICE food expert Rachel Clemons

"Food can be eaten and sold after this date and it'll often be perfectly acceptable."

So if you're chucking out items at their best-before date, you're wasting perfectly good food and money.

Try a little tenderness: storing leafy herbs such as parsley and basil takes a little more thought.

6. Putting your herbs in water on the bench

Woody herbs can withstand a bit of rough treatment, but leafy varieties such as parsley and basil need more tenderness. 

Fiona says they'll last longer if you wrap them in wet paper towel and pop them in an airtight container. But if you've returned from the farmers' market with an oversupply of fragile herbs, you can always whip them into a pesto or salsa verde and keep them for a few weeks.

7. Storing eggs at room temperature

It's generally fine to keep your eggs on the benchtop, but they'll keep far longer in their carton in the fridge. 

Although those plastic egg holders in your fridge may keep things tidy, it's better to keep your eggs protected in their cardboard, as this means you can keep an eye on their best-before date. It'll also stop the eggs from losing moisture and absorbing fridge odours.  

8. Keeping tomatoes in the fridge

Gorgeously fragrant fresh tomatoes will lose their aroma in the fridge, so keep them in a bowl on the benchtop, separate from other fruit and veg.

If they start to wrinkle up or slump a little, roast them with garlic and pass them through a mouli for a delicious, freezable pasta sauce.
