For NASA, the growth chambers on the space station are the predecessors of extraterrestrial farms beyond Earth. If human beings ever travel to another planet, they will need enough food for the journey. NASA has spent years perfecting thermo-stabilized or freeze-dried entrées and snacks for astronauts on the International Space Station, from scrambled eggs to chicken teriyaki. The meals are meant to last, but they wouldn’t survive the long journey to Mars, says Julie Robinson, the chief scientist for the International Space Station.

We're not looking at years if it's SS/SH.. more like 3-6 months at most. I agree that grow your own is vital but not because the food wouldn't keep.

What's supposed to spoil the food? I guess there must have been some misunderstanding, or she's never heard of Spam, not the new kind, the old kind :-)Ration packs, good for 3 to 5 years...''An MRE will store for about 5 years, if stored at 75° F or less. The cooler the temperature, the longer they will store. Some items in an MRE will last longer than 5 years, although the wet pack entrees typically expire within 5 years''.
Can China grow a flower on the moon? The countdown beginshttps://www.scmp.com/news/china/science/article/2181971/can-china-grow-flower-moon-countdown-beginsChang'e 4 includes a mini biological lab with plants and silkworms
According to Torres, during the first stage, they would cultivate easy-to-grow plants such as microgreens. He also said that in the midterm stage, they would grow crops like tomatoes and peppers. Finally, they would do long-term research on Mars soil to create a full-scale greenhouse.

That said, IAUI they aren't allowed to assume freezers will be available. (Same with ISS food storage.) So everything has to store at room temp or worse. I assume having enough power/thermal excess to run food freezers would make things easier.

So as I understand Quantum dots, they can absorbe light of different spectra, and emit a single frequency based on the size of the dot.I also recall a grade school science experiment involving celery and a jar of food-dye colored water.Might there be some practical benifit to growing a plant intended for low light in a QD-rich growth medium, such that light chrolophil is not well suited to absorb is converted by quantum dots into light it is suited to absorb?

You can't live for a NASA planned mission lengths on just MREs.Her team has been researching this for years. They keep various meals in storage for various times then check them for taste/nutrients/rancidity/other-spoilage. It's an issue. They're not just making crap up.That said, IAUI they aren't allowed to assume freezers will be available. (Same with ISS food storage.) So everything has to store at room temp or worse.
