Quick Answers

 

 

Many of our tomatoes have white pitted areas under the skin. What causes this and is it safe to can these tomatoes?


White spots, also known as "cloud spots," right beneath the skin of the tomato are caused by insects sucking juice out of the fruit. This damage can be quite extensive. These spots heal over leaving scar tissue that appears as a white spot. The surface area remains quite smooth. The acidity of the tomatoes should not be affected and the spots can be cut out as the tomatoes are prepared for canning. This particular exception, however, does not affect our general recommendation of never canning tomatoes with soft spots, broken skin or decay.
