There are agricultural products where price per bushel has to do with some grading, which is tested along in the supply chain. If I can easily, quickly, cheaply test for any trait, its value can be priced in. See how much apples have improved, given that we could tell varieties on sight, and people learn the properties that come with each variety. If you could tell whether a pepper's value in the scoville scale before buying, or the supermarket could accurately label things cheaply. the price differential, and therefore the quality, will follow.
