Organic Broccoli Packs a Nutritional Punch
Organic broccoli had significantly higher organic acid content, including vitamin C, than conventionally grown broccoli
It's no secret that broccoli is good for you. But the longer it takes this superfood to go from farm to table, the more nutrition it loses. A study in the Journal of the Science of Food and Agriculture found that organically grown broccoli may be more nutritious than conventional varieties, and that using a heat treatment after harvest can help keep broccoli fresher, longer.
Tiny trees bring good health
Chock full of vitamin C, vitamin K, folate, and antioxidant compounds called phenolics, broccoli may help aid in detoxification, lower cholesterol, protect against heart disease, and promote healthy skin. It's also a terrific source of anti-inflammatory and cancer-preventing compounds called glucosinolates.
Experimenting to improve preservation
Investigators from the UK and Spain set out to extend broccoli's shelf life and optimize its nutritional profile. The broccoli was grown in two adjacent fields in Spain. One crop was treated with conventional methods, and the other was organically grown (without the use of synthetic pesticides or fertilizers). After harvest, the broccoli was divided into four groups:
Before treatment, and periodically for eight days, the broccoli was examined for color, weight, and chemical characteristics, including organic acid (like vitamin C and malic acid) and phenolic content, and total antioxidant capacity (a measure of free radical-fighting ability).
Broccoli heads that were assigned to the no-heat-treatment group were dipped in room temperature distilled water for 15 minutes. The heat-treated broccoli was dipped in 122F water for 15 minutes. The broccoli was then stored for eight days at 68F.
Treat your broccoli right
How you store and prepare your broccoli is just as important as how it's treated before making it to your fridge. Try these tips to optimize broccoli's nutrition:
