No study has been conducted to determine the mineral content of seeds belonging to different quinoa varieties under the conditions of Turkey. In addition, there is no study on whether quinoa seeds that containing high amounts of minerals can be utilized for mineral needs of laying hens in particular. In this study, which was carried out under Erzurum irrigated conditions, it was aimed to determine the mineral content of seeds belonging to nine quinoa varieties and whether they can appropriately utilize for meeting mineral requirements (as recommended by NRC) of laying hens. Significant differences were observed in the mineral contents of the varieties. The phosphorus, potassium, calcium, magnesium, iron, copper, manganese, zinc and boron contents of the seeds varied between 0.18-0.25%, 0.76-1.08%, 0.07-0.12%, 3427-5453 mg kg-1, 233.8-577.8 mg kg-1, 45.6-107.8 mg kg-1, 40.2-72.9 mg kg-1, 29.8-55.4 mg kg-1 and 48.3-94.7 mg kg-1, respectively. When these results were compared with the values recommended by NRC, it was seen that quinoa seeds could exceedingly meet the daily mineral requirements (except calcium) of laying hens. As a result, it has been revealed that the seeds of all quinoa varieties can be evaluated as an organic mineral source in the feeding of laying hens.

<p style="text-align: justify;">This paper describes the determination of iron, copper, manganese and zinc in the soils, grapes and wines of the three viticultural regions of the Azores. Iron, copper and zinc were determined by flame atomic absorption spectrometry and manganese by graphite furnace atomic absorption. The concentrations of the four elements differed in soils of the three regions; there was no difference in the concentration in grapes, whereas significant differences were observed for the wines as regards the amounts of iron, manganese and zinc. The concentrations of these four elements in wine correspond with the mean values observed for other European regions.</p>

Preparation Period

This method of sample preparation for iron, copper, manganese and zinc in wine were studied in this paper. At the preparation period adopted a method using nitric acid to extract, which mostly reduced the losing of metals and saved the time. Determinate the iron, copper, manganese and zinc in wine by AFS, and the recovery is in the range of 102.4 %~107.8 %, and the relative standard deviation is in the range of 0.955 %~3.806 %.
