“…Iron deficiency still remains a significant public health problem in the developed world and is particularly prevalent in less-developed countries. According to the National Institute of Health (NIH), the average daily iron requirements for adult men and women are 8 and 18 mg, respectively, while the requirements for children and pregnant women are 8 and 27 mg, respectively (NIH 2007;Kwak et al 2014).…”

Iron was incorporated at 20–60 mg/kg of yoghurt using iron‐encapsulated cold‐set whey protein isolate gel powder (WPI‐Fe) and by direct addition of ferrous sulphate solution. The changes in physicochemical and sensory qualities of the yoghurt samples were determined over 14 days of storage. Quality attributes of the yoghurt fortified using WPI‐Fe particles at up to 60 mg iron/kg were similar to those of unfortified control samples, especially in terms of colour and flavour, while the samples fortified by direct addition of ferrous sulphate exhibited noticeable adverse effects even at 20 mg iron/kg.

“…A further issue, which should be considered if migration of ENOs into food occurs, is possible changes of the food matrix itself by interaction with the migrated ENOs. ENOs have the potential to interact with functional groups of organic molecules, such as carboxyl, hydroxyl, amino or carbonyl groups, which may lead to changes of proteins, lipids and polysaccharides in food (Kwak 2014). …”

The use of nanomaterials in food-contact applications has created enormous interest in recent years. The potential migration of engineered nano-objects (ENOs) from food-contact materials (FCMs) is one of the most important concerns regarding potential human exposure to ENOs and health risks. Current research focusing on FCMs has often reached inconsistency regarding migration of ENOs. The scope of this critical review is to give a concise overview of the most relevant aspects of the subject, and to identify and discuss the major open questions in relation to migration of ENOs from FCMs. This includes the very fundamental questions whether ENOs can migrate from FCMs at all and what the potential release mechanisms of ENOs could be. The inconsistency of findings from experimental studies is highlighted based on the example of silver nanoparticle migration from polymer-based FCMs. Challenges in the detection and characterisation of ENOs in migration studies and the suitability of the most frequently used analytical techniques are discussed. Further, this review questions the suitability of standard food simulants and migration test conditions for FCMs as well as of conventional mathematical migration models. Considerations regarding the risk for consumers associated with migrating ENOs from FCMs are discussed. ARTICLE HISTORY

“…NG formulations are a form of nano-encapsulation. This technology comprises a process where core materials enriched with bioactive compounds are packed within inert wall materials, which protect and isolate the target product from the external environment [70,71]. Ionic gelation [61], coacervation, nanoprecipitation, inclusion complexation and supercritical fluid extraction are some methodologies that produce capsules in the nano-range [70].…”

Purification and Formulation of Xanthophyll for Pharmaceutical Use: Current Strategies and Future Trends

The increasing attention to biological activities of dietary xanthophylls demands the establishment of attractive and easy-to-implement purification protocols for their recovery from different sources. Bioengineering strategies that involve alternative isolation and purification techniques have gained interest since they offer practical benefits in comparison to traditional column chromatography methods. Furthermore, the use of these techniques has resulted in compound purities from 50 to 98 %. Besides purification, it is important to keep in mind that xanthophyll bioavailability is limited due to their low solubility in digestive fluids. Therefore, there is also the need to enhance xanthophyll bioavailability through formulations of the purified compounds. Several formulation techniques have been employed to obtain products for bioavailability or stability studies. However, there is a lack of studies that address the effect of the formulation upon the bioavailability and stability of these compounds. In the present review, emerging purification and formulation technologies that have shown potential for xanthophyll isolation and bioavailability enhancement are critically discussed. This analysis is presented in order to discuss the current trends in the purification and formulation technologies of xanthophylls, particularly for pharmaceutical use.
