Things That Go Bump

I don't pay much attention to sell by dates because they don't really mean much if the foods have met with any variables on their way to you,for instance twice this past summer I had bags of salad  that had been frozen in transit because the reefer truck was over refrigerating the load due to the outside temperature. The opposite can apply to milk and dairy products if they meet with heat in their handling. So with those things in mind the news of a bio-reactive bump to replace sell by dates is fairly exciting. The 23 year old industrial designer was looking for ways to improve life for the blind when she designed the gelatine label for foods. It starts out flush with the packaging but as the foods inside began to decay the bumps in the label can be felt. The labels work well with protein based products so the gelatine decays at the same rate,but she is working on altering the concentration to adapt it to other products. It would also be handy to not have to haul the reading glasses out for the smaller print dates.
