Reducing food waste is one key strategy to increasing food availability and ensuring that our limited global resources are better allocated. An international team of researchers from the United States Department of Agriculture and the Korea Food Research Institute has developed a novel microscopy technique that may help reduce food waste by identifying produce, specifically blueberries, that are more susceptible to spoilage.
