Sadržaj toksičnih i esencijalnih metala u ljekovitom bilju koje raste u onečišćenim i neonečišćenim područjima u Makedoniji
The aim of this study was to determine and compare Ba, Cr, Cd, Fe, Sr, Pb, and Zn content in medicinal herbs Urtica dioica L., Taraxacum officinale, and Matricaria recutita growing in polluted and unpolluted areas of the Republic of Macedonia. The metal content was determined using inductively coupled plasma atomic emission spectroscopy (ICP-AES). In the unpolluted area of Mt. Plačkovica the metal content in Taraxacum officinale was in the descending order: Fe>Sr>Zn>Ba>Cr, while Pb and Cd were below the limit of detection. In the polluted area of Veles, the order was as follows: Fe>Zn>Sr>Pb>Ba>Cd>Cr. Our results suggest that quality assurance and monitoring of toxic metals is needed for plants intended for human use and consumption. Medicinal plants should be picked in areas free of any contamination sources.Cilj je ovoga istraživanja bio utvrditi i usporediti sadržaj Ba, Cr, Cd, Fe, Sr, Pb i Zn u ljekovitom bilju Urtica dioica L., Taraxacum offi cinale i Matricaria recutita koje raste u onečišćenome odnosno neonečišćenome području u Republici Makedoniji. Sadržaj metala utvrdili smo s pomoću atomske emisijske spektroskopije induktivno spregnutom plazmom (engl. inductively coupled plasma atomic emission spectroscopy, krat. ICP-AES). U neonečišćenome području planine Plačkovice, sadržaj metala u Taraxacum offi cinale kretao se kako slijedi: Fe>Sr>Zn>Ba>Cr, dok su Pb i Cd bili ispod granice detekcije. U onečišćenome području blizu talionice olova i cinka u Velesu redoslijed je bio ovakav: Fe>Zn>Sr>Pb>Ba>Cd>Cr. Naši rezultati upućuju na potrebu za osiguranjem kakvoće i praćenjem razina toksičnih metala u biljaka namijenjenih ljudskoj uporabi. Ljekovito bilje valja brati u područjima bez izvora onečišćenja

Chemical and Sensory Analysis of Strawberry Flavoured Yogurt Supplemented with an Algae Oil Emulsion
A yogurt mix (2 g fat and 17 g solids/100 g) was supplemented with an algae oil emulsion to provide 500 mg v -3 fatty acids per 272 g serving of yogurt white mass. The emulsion was added to the yogurt mix either before or after the homogenization step and prior to pasteurization. It was then flavoured with a strawberry fruit base and fermented and stored for up to three weeks. The oxidative deterioration of the products was determined by hydroperoxide measurements and by trained and consumer sensory evaluations. The hydroperoxide content of the supple- mented yogurts increased over the storage treatment and was unaffected by the stage of addition. The trained panel could distinguish a stronger fishy flavour in both of the supplemented yogurts after 22 days storage, but the consumer panel rated both control and supplemented samples similarly, as ‘ moderately liked ’

Sensory Properties of Vanilla and Strawberry Flavored Ice Cream Supplemented with Omega-3 Fatty Acids
An ice cream mix (14% fat, 40% solids) was supplemented with an algae oil emulsion to provide 300 mg ω-3 fatty acids per 65 g serving. After addition of the emulsion, the ice cream mix was flavored with either vanilla or strawberry liquid flavoring, frozen and hardened. Trained and consumer panel sensory tests were performed on the product within 2 weeks of manufacture. Trained panel evaluations were used to scale the level of fishy off-flavor and consumer sensory evaluations were done to assess the overall acceptability of the products. The trained panel could distinguish a stronger fishy flavor in both algae-oil supplemented ice creams. The consumer panel rated all products as moderately liked although they significantly preferred the control vanilla ice cream to co-3 fatty acid enriched vanilla ice cream and the ω-3 fatty acid enriched strawberry ice cream over the control strawberry ice cream
