Engineers are looking to turn discarded avocado seeds into a tasty snack. 

Industrial production of cold-pressed avocado oil produces a large amount of avocado seed waste, but now Kiwi researchers have been able to extrude this waste into a porous puffed snack. This type of snack makes up around half of the ready-to-eat snack market. 

According to tests so far, the extruded avocado seed product has a higher antioxidant capacity than brown rice or malted barley, and non-toxic levels of the toxins amygdalin and persin. 

The authors say the process looks promising, and now more work is needed to find out if customers would find the snack appealing.
