Australian nutrition scientist reveals complete guide to freeze food

If you have scraps of pasta or rice, consider freezing them to use as servings for an easy-to-carry meal option.

If you are trying to reduce the cost of your weekly grocery receipt, freezing food is a great way to save.

According to the Australian nutrition specialist, Dr. Joanna McMillan, there is a whole range of foods that can be frozen, which makes it an ideal way to manage excess waste.

"Freezing is a really amazing way to preserve food because you do not have to use chemical preservatives," Dr. McMillan said on Today.

"Actually, it's one of the oldest ways to preserve food. In fact, it's not very good in the current era where we think everything has to be fresh. "

She said that foods like cooked rice and pasta are perfect for freezing and her suggestion is to always cook a little more and leave leftovers in serving size bags.

Dr. McMillan said that having some cooked portions by hand can relieve pressure if time is short after work and a quick meal is needed.

The expert recommends removing the pasta and rice from the freezer ahead of time to make sure it is defrosted properly.

Pasta and rice have a suggested storage time of one to two months after they have been frozen.

The nutrition scientist also revealed that the nuts froze particularly well and this was a great option to keep them fresh for longer.

The recommended amount of time to store the nuts in the freezer is one year.

Flour is another food that can be frozen, Dr. McMillan revealed.

It should be kept in an airtight container and the flour can be frozen for a maximum of two years.

Bananas that are beginning to brown can also freeze, however, Dr. McMillan recommends peeling and cutting them first.

Which foods do not freeze well:

Foods that contain a high water content do not freeze well.

These include vegetables such as celery, lettuce, zucchini, cucumber, cabbage

"They're great to use in cooking if you're making muffins for kids or to add to smoothies," he said on the show.

The frozen bananas will last between three and four months in the freezer.

While freezing food helps control waste, Dr. McMillan said it was worthwhile to be aware of the fact that freezing does not completely stop the growth of bacteria.

"It will often make the bacteria inactive, so if the food is a little old, that's the kind of thing you do not want to put in the freezer," he said.
