‘The browning of an avocado is a natural chemical reaction called oxidisation that occurs when a cut avocado is exposed to oxygen in the air,’ she explained.

‘While it’s safe eat, brown avocados are not very aesthetically pleasing & can taste a bit bitter,’ she added.

The first hack she shared was to squeeze lemon over the freshly cut avocado, being careful to rub the juice into the flesh.

The second technique requires olive oil.

‘Coat the flesh of the avocado with olive oil,’ she said – showing herself drizzling it over the top.

The third method involves a red onion.

The dietitian simply placed the flat side of a halved onion on top of the cut section of the avocado.

She said storing them together in this way would stop the green fruit from changing colour.

She finished the long post with a tip on ripening the fruit.

‘If you want to speed up the ripening of you avocados, place them in a brown paper bag with a banana or apple,’ she said.

The video has been seen by more than 21k avocado lovers.

‘Oh, I didn’t know the red onion one,’ one woman exclaimed.

‘Great advice, I had no idea,’ one mum said.

A fellow dietitian said they use lemon juice every time.

Some people weren’t quite sold on the red onion tip.

‘Won’t it taste like onion?’ they asked.

‘Half way to guacamole,’ the dietitian replied.

Another woman claims she just runs water over her avocadoes to stop them from going brown and says it ‘works a treat’. 

Another woman seconded the water trick but said it didn’t work for as long as using lemon or oil.
