Just a few weeks ago we were talking about the alarming decreasing nutrient content in crops, and up pops a tool to measure same in real time. Via NewScientist (23 September 2017):
FARMERS can now zap their crops with a handheld scanner to instantly determine nutritional content, which could prove crucial in mitigating the effects of climate change on food quality. It also brings similar consumer gadgets a step closer – so we can find out what is in our food for ourselves.
The device, called GrainSense, analyses wheat, oats, rye and barley by scanning a sample with various frequencies of near-infrared light. The amount of each type of light that is absorbed allows it to precisely determine the levels of protein, moisture, oil and carbohydrate in the grain.
This technique has been used for decades in the lab, but this is the first time it has been available instantly on a handheld device. …
GrainSense will be launched at the Agritechnica fair in Hanover, Germany, in November. And Krogius and his team are already thinking about adding corn and rice to its repertoire. But the technology could be adapted to assess the protein content of any organic material, including meat.
Other companies are developing similar gadgets for consumers, and sensors that can be fitted onto a smartphone. Whether we all start making healthier food choices is another matter.
I haven’t heard anything about nutrition level decrease deniers, but I shouldn’t be surprised to hear of them. This might put a stake right through the heart of such a movement.
And this might be the one kooky kitchen gadget I will have to get. Although it might induce a sense of foreboding as the years pass.
