James, over at James and the Giant Corn, has written a post about the long lasting tomatoes from India: Scientists at India’s NIPGR Create a Longer-Lasting Tomato (Studying The Regulation of Fruit Ripening). He does a great job of explaining cell wall chemistry, which I neglected to cover in I say tomato… I appreciate that he pointed out something that I forgot to mention (emphasis added): I shouldn’t have to say this, but there Ah, it is so nice to have a video program that does what I want it to do! This is an interview with Robert McDonald at The Nature Conservancy about genetic engineering, agriculture, and how the panel discussion went that he participated in at the 2009 BIO Convention in Atlanta last May. What I find refreshing about The Nature Conservancy’s position on genetic engineering – agnostic – is that it allows them to criticize
One of the things that we discovered while kicking around my place of origin is that we could very easily keep talking about GE crops and related issues until our voices ran out. We covered a lot of ground and have since thought that it would be nice to share some of those thoughts in more ways than just through written paragraphs. We recorded a video conversation right after we got back to my folk’s place from Chez Panisse, which I should have edited pretty soon, for example, and then there’s also the interview for my radio show. But we would like to do more. What do y’all think about a Biofortified podcast?
Continue reading… Researchers at the National Institute of Plant Genome Research in India have found a surprisingly simple way to extend the shelf life of fresh tomatoes. Most tomatoes will last about 10-15 days before going unappealingly squishy. The enhanced tomatoes last 45 days or more and are firmer than unmodified tomatoes, which I imagine makes for great tomato sandwiches! Before getting into the how, let’s talk about why this research is important. According to Enhancement of fruit shelf life by suppressing N-glycan processing enzymes in this week’s PNAS, post-harvest fruit and vegetable softening is a big problem, with losses accounting for almost 50% of all produce in developing countries. India, the country that funded the research, and the world’s 2nd largest fruit and vegetable producer, loses 35-40% of produce to softening. We all know that post-consumer food waste is a big problem, and we can alleviate this somewhat in our homes and by choosing restaurants that try to reduce waste. But there isn’t much we can do about pre-consumer waste – from grain that rots in the silo due to fungus to tomatoes that rot in transit due to ripening. By reducing pre-consumer food waste, we can reduce the number of acres needed to produce the same amount of food. In India, preventing all fruit and vegetable softening would be like reducing the amount of land needed to grow fruits and vegetables by 35-40%! I finally got signed up for a vegetable share with Small Potatoes Farm through Farm to Folk, our local CSA (Community Supported Agriculture) program. This is the fourth year that I’ve had a CSA and I love it. I’m really looking forward to spring, and not just because I don’t want to look at snow anymore. Having a CSA share is such a good experience in so many ways, but the most important one |
