The influence of mycorrhizal fungi in uptake of heavy metals, pollution response index and yield of sunflower in degraded soils were investigated. It was a greenhouse experiment with 2 arbuscular mycorrhizae (Glomus mosseae, Glomus intraradices) and a non-inoculation that served as control. The treatments were replicated 3 times in a completely randomized design. Each of the treatment consisted of 30 pots and each pot was filled with 5 kg by weight of dried top soil.

The results obtained by the analysis of the samples of coffee mostly consumed on our market showed that the coffee quality corresponds to the values as given in the Law of Health Food. It was not found that any of the parameters which determine food quality exceeded permitted values. Content of heavy metals and aflatoxines is below permitted values. The least content of caffeine was determined in a coffee sample roasted in the private roaster’s shop, and only in it the presence of coffee surrogates/substitutes was not proved.

It is possible to decompose starch into monosaccharides by the method of acid starch hydrolysis. By applying appropriate chemical procedure, a main solution is obtained, from which aliquots are taken after filtration to determine of the present glucose according to Luff-Shoorlu method. The analysed potatoes of cv. Desiree, grown on various sites in Serbia, have starch content that corresponds to available literature data. The highest starch content is found in potatoes from Ivanjica and Novi Pazar, i.e.

The result of examination of oil of unknown origin from the crisis territory as follows: the examined oil has qualities permissible for human nutrition. The examination of contained quantity of contaminants and heavy metals showed that ingredients were not higher than values prescribed by the Statute, except for lead. It is on the upper limit. Contents of radionuclides range within the limits of average values. The quantity is not dangerous for human food.

Phosphogypsum is formed as a by-product in the process of 'green' phosphoric acid production. This is done in the so called 'wet process' by the action of sulphuric acid on raw phosphate at low temperature (<100 °C). Despite the same molecular formula and marked similarity with natural gypsum, phosphogypsum contains more than 50 impurities, and this is directly connected with the type of phosphate used in the production cycle.

Beer-based drinks, 'Radler' type products in particular, arouse interest for a number of reasons. These newly produced drinks were obtained by mixing beer and soft drinks and are intended for a larger number of target groups than their each single component. Also, they combine advantages of both components in physiological respect.
