FOOD52 - A few years ago, an Australian company called Naturo Technologies invented a machine—the Natavo Zero, aka the Avocado Time Machine. This ATM supposedly miraculously slows the avocado ripening process, keeping it from turning brown for up to 10 days without the use of chemicals—or olive oil, or lemon juice, or red onion. (Naturo Technologies is currently working on a new process of pasteurization that leaves more of the natural vitamins and enzymes in the milk.)

So the impact of oxidation on avocado flavor is a bit up in the air. Eric Focht, a staff research associate at the University of California Riverside, said he wasn't aware of any blind taste tests of browned versus freshly-cut fruit. But, he'd "bet that if the subject couldn't see what they were eating, they'd notice little difference; I know I don't." Most of the aversion, he hypothesizes, is psychological: "We don't like the way it looks, so it's off-putting. A big part of food is its presentation, and we associate browning or discolored fruit with being bad or overripe or even rotten."
