Seeds vs. sprouts: red cabbage and broccoli

This 2021 study compared properties of red cabbage and broccoli seeds and sprouts:

“Antioxidant and antidiabetic properties and metabolite profiling of ethanol extracts of red cabbage (RC) and broccoli (BR) seeds and sprouts were investigated:

  • BR seeds had the highest total phenolic and flavonoid contents;
  • BR sprouts had the highest saponin content;
  • RC sprouts demonstrated the highest antioxidant capacity;
  • BR and RC sprouts showed the most potent inhibition against α-glucosidase and pancreatic lipase; and
  • BR seeds demonstrated the lowest AGE inhibition.

RC and BR seeds vs sprouts

In vitro assessment of antidiabetic potential of extracts revealed that sprouts demonstrated better potential as antioxidant, α-glucosidase, and pancreatic lipase inhibitors compared to raw seeds. Amino acids and phenolic compounds were the most improved metabolites in the germination process.

Germination not only enhanced levels of metabolites, but also synthesized new compounds in seeds. Germination effectively enhanced functional properties and metabolite profiles of broccoli and red cabbage seeds, making their sprouts more applicable as functional ingredients.”

I asked coauthors for sprout ages and pertinent growing conditions for the above-pictured sprouts. I’ll guess > 3-days-old, temperature 25° C, and relative humidity 90%. What would you guess?

Update: Two coauthors replied:

“Red Cabbage and Broccoli were germinated for 6 and 7 days respectively. Temperature ranged between 20-23 °C in the dark.”
