The white stuff on Motts is starch.
The starch on Motts and Motts fruit snacks accumulates during the process of manufacturing and leads to the white appearance.
The white stuff on Motts is safe to consume and does not mean the Motts fruit snacks are bad.
Mott's fruit snacks are also made with 100% fruits and vegetables, the Carrots represent the veggies!
Mott's fruit snacks are healthier than a lot of other snack options on the market and do have real fruit ingredients, but must be eaten in moderation.
They also can't be considered as healthy as fresh fruits or fruit snacks that don't include artificial ingredients or added sugars.
Fresh fruit is healthier than fruit snacks but the fruit snacks are healthier than other junk food snacks.
