Pre-prepared brassicas "have poorer flavour" says specialist grower

Chopping kale and other brassicas in advance adversely affects their taste, Lancashire specialist grower Chris Molyneux said during a tour of his field as part of today's AHDB GREATsoils grower event.

"The glucosinolates in brassicas convert to nitriles when the plant is damaged, so when they're chopped and prepared they won't have as good a flavour," he told fellow growers and suppliers. "It's part of the plant's defence mechanism."

He added: "Brussels sprouts left on the stalk will taste better. I have done taste tests at Booth's supermarkets comparing freshly cut leaves to those cut the day before. There is a clear difference."

Molyneux was demonstrating the effect a range of green cover crops on his fields near Ormskirk, which he said improve soil health and so crop quality.
