Fruit carotenoids better choice for functional ingredients

Fruits and vegetables are rich sources of health-promoting nutrients called carotenoids. However, benefits to human health depend on how well these nutrients are absorbed by the body after digestion. A new study has shown that fruit carotenoids are better absorbed than those from green vegetables. This means that fruit carotenoids may be a better choice as ingredients for functional food and beverage products.

A study by Irish researchers used an experimental model of the digestive process to test the bioaccessibility of carotenoids, such as beta-carotene, lycopene, zeaxanthin and lycopene. Bioaccessibility was defined as the amount of carotenoids available for absorption after digestion.

The results showed that 50 to 100% of carotenoids in fruit were bioaccessible but that the corresponding figure for green vegetables was only 19 to 38%. The reduced bioaccessibility seen in green vegetables may be due to the higher fibre content, which is known to trap nutrients.
