Blasting Yeast with UV Light

Or, if you're making orange juice, make the ingredients label say oranges. But you can split it up, take the peels, put them into a hydraulic press, extract out oils that have the concentrated aroma and flavor of oranges, homogenize some of that into the juice. Or you can centrifuge the juice, or you can pass it through osmotic filters to remove some of the water and concentrate the flavor. No rule saying you can't treat some of the juice similar to sugar beet juice and try to isolate its sugars. At the end, you reassemble a perfect consistent mixture. The label doesn't have to tell you about any of this, it just has to tell you that the ingredients were oranges.

(The recipe for the best lemonade you'll ever make is like this, it's just lemons and water and sugar, but you zest the lemons into the simple syrup you're making with the sugar water, then strain it with cheesecloth or a coffee filter, before adding to the juice and water and pulp.)

Imported oils, you can basically do anything that some middleman country allows you to do with the oil (in particular mix with cheaper oils) and then say "oh this is imported olive oil, olive oil according to someone else's standards”...

Looks like when law enforcement does the infamous parallel comstruction trick, gathering evidence through illegal means and later pretending to have just discovered what they secretely already know, but through legal means this time. See https://en.wikipedia.org/wiki/Parallel_construction

But nowadays we have things like single cell sequencing, which allows you to label thousands of cells with unique DNA barcodes (not the cell itself but the sequencing library you construct to go into the sequencer), and sequence them all in a massive parallel fashion.

Basically all of molecular (and other types) biology is now "high throughput", consequently data science has become very important for biologists.

Once you know what it is, you run the same thing on the unmodified population.
