我喜欢鳄梨，但对他们感到沮丧。似乎无论我做什么在成熟的高峰期购买它们，除非我在完美的分钟内使用它们，否则他们将它们陷入粘性的棕色领域，然后我必须折腾它们。
Turns out, I’m not alone in my plight, which is why Santa Barbara company Apeel Sciences (with backing from the Bill And Melinda Gates Foundation) has been working on a new coating that would help prolong the edible life of not just avocados, but mangos, strawberries, apples, bananas, kumquats, and asparagus. It’s made from “naturally occurring lipids extracted from discarded fruit or vegetable waste” like grapes or tomatoes, making for an edible coating—not that helpful for avocados, but good for strawberries.守护者解释：
由Santa Barbara Company Apeel Sciences开发的无味涂层控制了导致新鲜农产品的两个主要因素变坏：水逃离水果和蔬菜表面的速度以及氧气进入的速率。这使得经过处理的产品将保持清新。
The produce won’t last forever or anything, but this coating—which will be sold in the U.S. for the first time this week in nationwide Costcos and Harps Food Stores in the Midwest—should add at least a few more days onto that elusive ripe-avocado window. It will also combat the tremendous amounts of food waste that gets tossed every year due to over-ripe produce. For avocado-toast and guac lovers like myself, I can’t think of a more exciting scientific discovery.
