Company Determines Optimum Phytochemical Harvest Time For Buckwheat

A company that provides health care professionals with organically-grown whole food supplements has published a research paper analyzing the antioxidant activity of buckwheat throughout its various stages of growth. The goal of the study by Standard Process Inc.  was to determine the optimum time to harvest the plants. According to the company, levels of phytochemicals, such as carotenoids, fluctuate dramatically over the life cycle. But while scientists are well aware of rutin concentrations, similar information is lacking in buckwheat. Over the life of the plants, researchers analyzed the levels of lutein, beta-carotene, rutin, and anthocyanins. Allowing for plant size and yield, they determined that optimal harvest time for buckwheat is 4 – 5 weeks after sowing. The research is ongoing and will be revisited to make sure recommendations remain accurate.
