Why do tomatoes turn some soaps yellow?

christopher_reality asked the Naked Scientists:
   
Hello,

We really love the show and I would like to ask a question.

I grow tomatoes in our garden and I have noticed when I come inside from trimming them or picking tomatoes my hands are bright yellow.

When I wash my hands with anti bacterial hand soap, the bubbles are white and clean, but when I wash my hands with a bar of soap, I notice that the bubbles have turned yellow.

Even when I wash my hands with the bar of soap after using antibacterial soap the bubbles are still yellow.

What has the bar of soap got that the anti bacterial soap doesn't?

We really love the show.

Thank you

Steve

What do you think?
