Scientists at Plant & Food Research analysed the concentrations of 27 compounds thought to be beneficial to health in 109 different cultivars of apple – 94 from the Plant & Food Research germplasm collection and 15 grown in Luxembourg.
From these, five cultivars were selected that represented the extremes of chemical profiles identified. Extracts of the flesh and skin from each of these cultivars were analysed in laboratory cell-based assays for the apples’ effect on key components of human inflammation.
The results showed that the apples with high levels of two families of compounds -the procyanidins and triterpenes – inhibited the activation of two molecules known to play a role in inflammation and are key in inflammatory diseases, such as Inflammatory Bowel Disease (IBD).
Dr William Laing, science group leader biological chemistry and bioactives at plant & food research, said: “Apple is one of the most highly consumed fruits worldwide.
“Understanding which compounds in apple influence pathways in disease, such as IBD, allows us to breed new varieties of apple with more of these compounds that can then be used as ingredients in foods specifically designed to control the disease symptoms.”
