Running out of cooking oil or need some dressing for your salad?The solution may be bugs from your backyard!Scientists are turning insects into a source of eatable and healthy oil.Even though serving insects as dishes is common in some parts of the world,to many people,the thought of eating them is rather disgusting.
In the Western countries,there is no culture of eating entire insects.So when the idea is to use the protein in powder as an ingredient,people might tend to receive this protein better,on condition that they cannot see it."said researcher Daylan Tzompas-Sosa,Wageningen University,Netherlands."There are many uses for the oil in general,but we are investigating the use of these oils for a food,as a food ingredient."
The Mexican researcher,working in the Netherlands,said insects are a great source of heart healthy omega-3fatty acids,which can help treat anxiety disorder symptoms.Backing up the increased reliance on insects is the United Nations Food and Agriculture Organization.In a 2017report,the UN agency approved the cultivation of bugs as a food source,saying it's environmentally-friendly and could increase the world's food production.
There are clear reasons why experts advise people to eat the insects.Experts say insects require little food to grow and that the backyard can be a good place to raise them.And there's no shortage of protein-rich insects,which also contain fat,vitamins,fiber and minerals.
Researchers say different bugs provide unique tastes and textures."This is very liquid and it has a different color,so this can be used as a dressing for example and it's easy to use and this can be used for example for pastry (油酥面團(tuán)),because for pastry you need hard fats,"stated Tzompas-Sosa.
But not all insects produce good oil.Cockroaches (蟑螂) don't.The bug oils must be tested to make sure they are safe to consume.But getting over the"disgusting feeling"may be a bigger challenge.
