The aim of the work was a practical verification of assumption of the innovative method based on SSSA (Surface Spectrofluorimetry Shapes Analysis) conception. The results of floral types evaluating of honey were checked by the well-established melytopalynology method of honey identification. The new method of honey identification docs not require much time and costly preparations of samples, before their measurement The nature of the samples is preserved during its examination, as well. It is possible, that methods based on SSSA conception may constitute quick analytical procedures of nowadays.

The aim of this study was qualitative analysis of phosphates in meal concentrates. Additionally, the levels of total phosphorus, Ca, Mg, Fe, Zn and Mn were determined in all tested products. Results received were used to calculation of RDAs for these elements by one average portion. The content of phosphorus and other elements after wet mineralization in a microwave mineralizer was measured with the following methods: phosphorus by the spectrophotomertic method according to Scheele and other elements by flame atomic absorption (ASA). According to our findings total phosphorus ranged from 115,1 mg to 358,4 mg/100 g of meal concentrates. Phosphates added to the meal concentrâtes were identified by thin-layer chromatography. No prohibited phosphates were found in the meal concentrâtes investigated. Orthophosphates were in all analysed products. The concentration ranges of other elements were as follows: for calcium from 41mg to 474,1 mg/ 100 g product; for magnesium from 18,1 mg to 88,6 mg; for iron from 1,08 mg to 5,48 mg; for zinc from 0,54 mg to 2,51 mg; for manganese from 0,17 mg to 1,29 mg /100 g product. In conclusion, all tested products weren't rich in analysed minerals. One average portion (20 g) of meal concentrâtes covers for phosphorus maximally in 5% of RDAs. For other elements it is even less. Our study demonstrated that in meal concentrates the average proportions of calcium, magnesium, iron, zinc and manganese to phosphorus were very unprofitable. Such excess of phosphorus may impair the absorption of other minerals.
