Macro and micro minerals: are frozen fruits a good source?

Abstract

Fruits are rich in minerals, which are essential for a wide variety of metabolic and physiologic processes in the human body. The use of frozen fruits has greatly spread in the last years not only in the preparation of juices, but also as raw material for yogurts, candies, cookies, cakes, ice creams, and children's food. However, up to now there is no data about the mineral profile of frozen fruits. This is the first database to quantify the levels of minerals in 23 samples of frozen fruits, including the most used around the world and some native fruits from the Amazon rainforest in Brazil. Considering the Dietary Reference Intakes, 100g of frozen fruits can provide 0.2 to 2.8% of macro and 2.5 to 100% of microminerals for adults (31-50 years old). Although geographical differences should be considered, these data can help to plan diets and to develop population interventions aiming to prevent chronic diseases.

Quality pattern evaluation of frozen soursop pulps: an assessment based on chemical composition and chemometric analysis

“…However, contributions from the calcium and zinc RDOs do not reach 1.6% for either age group. These values are similar to those found by Spada et al (2010), who reported a contribution of 0.5% for calcium RDO and approximately 2.0% for manganese RDO from the consumption of a 100 g-portion of soursop pulp.…”

“…Low zinc contents were determined in all the frozen pulps analyzed (< 0.85 μg g -1 ). Spada et al (2010) did not find Cu, Zn and Mn in some of the frozen soursop pulps marketed in the state of Rio Grande do Sul, Brazil. The absence of these elements may be related to different growing conditions (Tiburski et al, 2011).…”

Distribution of elements in seeds of some wild and cultivated fruits. Nutrition and authenticity aspects

“…The manganese level was also the highest in bilberry seeds (0.189 g kg −1 dw), which agrees with Ekholm et al . but is much higher than the results for Spada et al . Wild fruits may also be sources of dietary copper, providing values of over 0.016 g kg −1 dw – for example Prunus avium and Prunus spinosa .…”

Bioactive compounds from Cucumis melo L. fruits as potential nutraceutical food ingredients and juice processing using membrane technology

“…Indeed, a number of microminerals such as manganese, copper, and zinc are cofactors of many enzymes. As well, iron is a component of several enzymes in the muscle cells (Spada et al, 2010 ). Based on the above results, it is noted that Maazoun flesh is rich in minerals, particularly potassium, magnesium, and calcium, which could be salutary for human nutrition.…”
