Changes in the mineral and trace element contents of cereals, fruits and vegetables in Finland

Evaluation of beetroot (Beta vulgaris L.) leaves during its developmental stages: a chemical composition study

“…Beetroot leaves contain high amount of Cu, similar to the levels reported for watercress and rocket (Ekholm et al, 2007). High K contents were determined, as expected for vegetables and fruits since K + is necessary for the metabolism of carbohydrates and proteins 3 and the RDI for potassium varied from 1,950 to 5,900 mg/d (Brasil, 1998).The consumption of 145 g (about 4 cups) of DBL provides the recommended amounts of potassium.…”

“…Fe is a component of the hemoglobin molecule, which is essential for the transport of oxygen and cell breathing. These elements are found in cereals, fruit, and in roots and leaves of vegetables (Ekholm et al, 2007;Kawashima & Soares, 2003).…”

Status of Fe, Mn and Zn in red beet due to fertilization and environment

“…Again, the highest values were recorded in Brašljevica in 2003 (50-60 mg Zn*kg -1 in dry matter). It is worth highlighting that the obtained red beet zinc content is higher or similar to the data in the literature Silanpää (1982), Mikula and Indeka (1997), Sękara et al (2005), Lisiewska et al (2006), Ekholm et al (2007) and Nizioł-Łukaszewska and Gawęda (2016) (52,44,33,41,16 and 45 mg Zn*kg -1 respectively).…”

“…Despite the finding that fertilization did not significantly increase the red beet iron content, there were very interesting and important findings, namely, that the red beet iron content obtained in this study (annual average values ranged from 96 to 270 mg Fe*kg -1 in dry matter) is significantly higher than that reported in the literature (Silanpää ,1982;Maynard and Hochmuth, 1997;Kołota and Adamczewska-Sowinska, 2006 The red beet manganese content was highest in Brašljevica in 2003 (83-106 mg Mn*kg -1 in dry weight), and among the treatments, the highest value was obtained in the control treatment. This value is also higher than those reported by many authors (Lindow and Peterson, 1927;Mikula and Indeka, 1997;Lisiewska et al, 2006;Ekholm et al ,2007;and Nizioł-Łukaszewska and Gawęda, 2016) (35-76, 26, 27, 30 and 26 mg Mn*kg -1 , respectively). In terms of red beet zinc content, variation among studied environments was found.…”

A comparison of macro- and microelement concentrations in the whole grain of four Triticum species

“…However, little information is available on the differences in the chemical composition, nutritive value and baking quality of the cultivars under production (Stallknecht et al 1996, Abd-el-Aal et al 1997. Ekholm et al (2007) reported that the trace element concentrations in plants are known to be affected by the cultivar, soil conditions during growing, the use of fertilizers and the state of maturity at harvest. The knowledge of the microelement content of food products is very important because of their fundamental nutritional role in the human diet.…”
