- Functional foods have a nutritive value and appearance similar to conventional foods, but they bring additional health-promoting effects and/or disease-preventing capabilities when consumed as part of a varied daily diet. These can occur naturally or be developed through processing or agro-biotechnological strategies. However, modified or not, they must always be safe, without any consideration of a trade-off between health benefit and health risk (Pinela et al., 2016). Nowadays, processing and preserving functional foods, whether solid or liquid, is a major scientific challenge since the factors involved can lead to the degradation of micronutrients and bioactive compounds and affect physicochemical parameters.
