AB  - Total fungal count, incidence of fungi and aflatoxin B1 (AFB1) concentration were studied in 33 samples of bee pollen randomly collected from beekeepers in Serbia. The total number of fungi was determined by dilution method whereas AFB1 was detected using the Enzyme-Linked Immuno-Sorbent Assay (ELISA). The mycological estimation showed the presence of nine genera of fungi as followed: Acremonium, Alternaría, Aspergillus, Cladosporium, Epiccocum, Fusarium, Mucor, Pénicillium and Rhizopus, with total number ranging from 1 x 103 to 1 x 105 CFU g-1. The results have shown the predominance of the fungi from the genera Aspergillus and Alternaria. Among Aspergillus species it was observed that the most frequent species was A. flavus with incidence of 27.27 %. Mycotoxin AFB1 was detected as 100% positive in all samples (100%) with an average concentration of 8.61 μg kg-1. The obtained results indicated that honey bee pollen must be strictly controlled during its manipulation in the harvesting and manufacturing. Therefore, the implementation of good manufacturing (beekeeping) practice to define procedures for honeybee products could be crucial to reduce the risk of possible contamination and provide natural and safety product without risk on the human health.
AB  - Ukupan broj gljiva, učestalost (incidenca) gljiva i koncentracija aflatoksina B1 (AFB1) ispitivani su u 33 uzoraka polena sakupljenih od pčelara iz različitih regiona u Srbiji. Ukupan broj gljiva određen je primenom metode razređenja a AFB1 je određen primenom imunoadsorpcione enzimske metode (ELISA). Mikološkim ispitivanjima identifikovano je devet rodova gljiva: Acremonium, Alternaria, Aspergillus, Cladosporium, Epiccocum, Fusarium, Mucor, Penicillium i Rhizopus, sa ukupnim brojem od 1 x 103 to 1 x 105 CFU g-1. Najučestalije vrste gljiva su u rodovima Aspergillus i Alternaria. Među Aspergillus vrstama najučestalija je vrsta A. flavus sa incidencom od 27,27%. AFB1 je detektovan u svim uzorcima sa prosečnom koncentracijom od 8,61 μg kg-1. Dobijeni rezultati ukazuju da pčelarski polen mora biti strogo kontrolisan tokom prikupljanja i njegove dalje prerade. Zbog toga, sprovođenje dobre proizvođačke (pčelarske) prakse podrazumeva definisanje procedura za pčelarske proizvode što bi moglo biti presudno za smanjenje rizika od moguće kontaminacije i dobijanje prirodnih i bezbednih proizvoda bez rizika po zdravlje ljudi.

AB  - The aim of this paper was to optimize the technological process of broccoli drying. The drying experiment were carried out in the laboratory dehydrator, at two temperature regimes of drying, batch process (constant air temperature of 70 °C for a period of 8h) and simulated continual process (the air temperature of 70 °C for a period of 3h and then the air temperature of 50 °C for a period of 5h). The amount of evaporated water was expressed in relative and absolute units of measure. The experiment was conducted to follow the moisture rate of drying of broccoli and was expressed as speed changes in the ratio of moisture content in the moist material depending on the current moisture content. The results showed that in simulated continual process of drying the lower maximum moisture rate of drying was achieved, drying was more evenly and in this way the technological process was finished with a smaller temperature stress for plant tissue, resulting in a better quality of the final product. The second temperature regime of draying, which simulated continual process, was more acceptable in terms of the final product.

AB  - In the present study, we investigated the use of spray drying as a way to prepare dairybased powders with high number of viable cells of the potential probiotic strain L. plantarum JS7A. Microencapsulation was done using reconstituted skim milk (RSM), inulin and maltodextrin as carriers. When RSM was used as a spray drying carrier a microbial survival rate of 73 % was achieved, although the partial substitution of skim milk with inulin also resulted in high level of survival of 70 %. The poorest survival of 41 % was obtained with maltodextrin as a carrier. The moisture contents in powders were ranging from 4.1 % to 4.4 %. Spray drying process stressed the cells which was shown by increased sensitivity to NaCl. However, it was obtained that reconstituted skim milk showed the significantly lower inhibition of cells of 49 % comparing with inulin and maltodextrin with 55 and 75 % of inhibition, respectively.

AB  - Packaging has an active role in processing, preservation and retaining the quality of the food. The growing consumers demands for the food that are ready to eat, fresh-tasting, nutrient and vitamin rich and minimally-processed and preserved are a major challenges for the current food industry. In order to realize these demands more significant role is gained to the packaging techniques and materials. Development in packaging is focused primarily towards the better protection of packaged food products, greater reliability, increased functionality, better environmental attributes of packaging, as well as in the development of new materials and packaging technology. In this paper the method of modified (protective) atmosphere packaging, biodegradable packaging as well as active and intelligent packaging are discussed. In addition the advantages of nanoscale materials for application in food packaging is also reviewed.
