AI Article Synopsis
- Orange juices have potential health benefits and vary in nutrient composition, particularly folates and minerals.
- A study analyzed 25 juice samples from various European countries, comparing fresh squeezed and commercial juices, focusing on their nutrient stability during storage.
- Results indicated that fresh squeezed and not from concentrate juices had higher folate levels, while juices from concentrate showed higher calcium, manganese, and zinc content, with both types meeting legal claims for potassium sources.
Article Abstract
Background: Orange juices are widely known for their organoleptic characteristics and potential health benefits derived from their nutritional and functional composition.
Objectives: The aim of this work was to provide comprehensive, up-to-date information on the content of folates and some minerals (Ca, K, Mg, Fe, Mn, and Zn) present in different fresh and commercial orange juices available in the European market, including juices from concentrate (FC) and not from concentrate (NFC).
Methods: A total of twenty-five juice samples were selected, comprising the most purchased types of commercial juices from France, the United Kingdom (UK), Germany, and Spain, and four fresh squeezed juices (FSJ) made from Spanish oranges. In FSJ, nutrient stability during storage time (0-48 h) was also assessed.
Results: Folate concentration was highly variable between commercial samples, with higher contents in FSJ and NFC samples, followed by FC juices. Regarding mineral content, FSJ showed significant differences with FC (except for Mg) and NFC juice samples (except for Ca and Mg), while FC and NFC had similar mineral profiles, except for Ca. Storage time had no significant impact on FSJ folates and minerals.
Conclusions: Among commercial juices, the NFC category generally showed the highest content of folates, K, Mg, and Fe, whereas FC juices showed the highest contents of Ca, Mn, and Zn. Some commercial juices met the legal use conditions for a "Source of folate" claim, whereas both commercial and fresh juices met the conditions for a "Source of potassium" claim, according to European and UK regulations.
