For water-soluble polyphenols, molecular weights between 500 and 3000 were reported to be required for protein precipitation. However, smaller molecules might still have astringent qualities likely due to the formation of unprecipitated complexes with proteins or cross-linking of proteins with simple phenols that have 1,2-dihydroxy or 1,2,3 ...

[4]In plants, algae, and other photosynthetic organisms, lycopene is an intermediate in the biosynthesis of many carotenoids, including beta-carotene, which is responsible for yellow, orange, or red pigmentation, photosynthesis, and ...
The glucose in corn syrup binds water well, helping prevent moisture loss and extending the shelf life of baked goods “without the cloying sweetness” of honey or other sugar syrups, McGee says.
Nature, traditional agriculture methods, and plant breeding have produced various uncommon crops containing anthocyanins, including blue- or red-flesh potatoes and purple or red broccoli, cabbage, cauliflower, carrots, and corn. Garden tomatoes have been subjected to a breeding program using introgression lines of genetically modified organisms ...
A pantry full of canned goods will come in handy when you're whipping up a quick meal. But it's safe to say that many cans probably linger a little too long in your cupboard. Maybe you're making ...
