In the selection of canned fruit, first of all, we must look at the appearance of the canned fruit pulp.

Normal canned fruit of yellow peaches, the color of its products should be less uniform, there is a golden yellow, and a little bit with green. Fake canned yellow peaches pulp is completely uniform, the color looks very nice. Normal canned yellow peaches it's soup should be colorless, and after dyeing the can, the soup is yellow.

For canned strawberries, look at the broth first. If the juice is very red, it is dyed, and if the juice is slightly pink, it is normal. The size of the pulp is also worth noting. Dyed canned strawberries, the pulp is immature, will be relatively small.
