This is Lee Min-a, playing with her young children.
The playdough they are playing with is made from sugar and milk so there's less of a choking hazard, and it isn't toxic.
Children tend to put things like toys in their mouths but with this edible playdough, parents have one less thing to worry about.
"It's made of milk there are no safety concerns. I worry less now, even if the children have to play by themselves."
The playdough is made using a process where protein powder extracted from milk is mixed with water and vinegar.
Various colors are added, not by adding artificial coloring, but food like grapefruit or sweet pumpkin.
Its powder base doesn't go off quickly either so it can last for over a year.
"It was during a start-up class I took in college where I thought of using the leftovers of oversupplied agricultural and fishery materials to make safer toys for children."
The edible playdough has already been safety-approved and has received both Korean and European safety certificates.
The next step is to discover other safe raw materials.
"There's parts of rice that get thrown out in the milling process. I'm thinking of developing another fun toy by adding color to the rice."
The project has earned support from public institutions for its outstanding developments in the agricultural field.
"Our aim is to help young people with ideas start businesses, as well as to actively support the promotion of the product to the public."
What's left now is to strengthen commercialization of the playdough by creating kits that allow children to make their favorite shapes.
