Berry pigments and herb oils could replace synthetic food preservatives

Medicinal Plants
The deep purple in your blueberries, the bitter tang of dandelion greens, and the aroma of rosemary in your herb bed all come from the same class of protective compounds this review says could replace synthetic preservatives in your pantry.
Plants make their own natural sunscreen and armor against stress in the form of antioxidant compounds like polyphenols, terpenoids, and vitamins, and it turns out these same molecules can protect human cells too. Scientists reviewed how plants build these compounds, how to pull them out efficiently, and where they're already being used, from coloring and preserving food to treating conditions like heart disease and diabetes. The tricky part is that these compounds are often scarce in the plant and break down easily once extracted, so better extraction methods are the current bottleneck.
Key Findings
Plant-derived antioxidants span five major classes: polyphenolics, terpenoids, vitamins, alkaloids, and saponins
These compounds show measurable effects against neurodegenerative disease, viral infection, cardiovascular disease, diabetes, and certain cancers by targeting oxidative stress pathways
Main industrial barriers are low natural abundance, extraction impurities, and poor post-isolation stability, prompting proposed fixes via synthetic biology, green purification, and nano-delivery
chevron_right Technical Summary
Compounds found naturally in plants, like those giving berries their color or herbs their aroma, can protect the body from cell damage as effectively as lab-made antioxidants, and researchers are working out how to extract them cleanly for use in food and medicine.

Gene editing removes 97% of celiac-triggering proteins from bread wheat
It could mean that people with celiac disease — roughly 1 in 100 worldwide — may one day safely eat bread made from real wheat, without sacrificing the taste...
Food forests are multi-layered agroforestry systems that mimic natural forest structure by combining trees, shrubs, and understory plants to produce diverse edible and useful yields. This approach interests plant scientists because it reveals how species with different growth habits, root depths,
