Consumers’ knowledge about proper household practises during food handling and storage are deemed insufficient. Therefore, the aim of our study was to investigate the conditions of food storage in refrigerators (temperature, hygienic and storage conditions) and consumer knowledge about good practises. This study included 100 households from the Belgrade area. All participants were interviewed using a standardized questionnaire. The internal temperature of refrigerators was measured at three points: the top and bottom shelves and the refrigerator door. The average temperature in the refrigerators was 9.3°C. The average temperature recorded in the refrigerator doors was significantly higher (P < 0.01) than temperatures recorded on the top or bottom shelves. The age and design of refrigerators, and potential heat source near refrigerator can impact the refrigerator temperature. In 50% of the surveyed refrigerators, food storage practises were incorrect. More than a half (56%) of the surveyed consumers were aware of the recommended refrigerator temperature, but measured temperature in their refrigerators was considerably higher. The results from our study indicate that knowledge of recommended behaviour about good food safety practise do not always translate into practise in the home.

Abstract:Grains have great agronomic and economic importance and they are one of the most important plants. Triticale is modern cereal grain, hybrid of wheat and rye, which inherited the ability of the rye to survive the high frosts, but has a higher protein value than rye, while higher grain yields and increased tolerance to diseases were inherited from wheat. The way in which triticale will be used depends on the characteristics of the variety. Triticale varieties of large and uniform grains which have more proteins then starch are used as concentrated feed for poultry, ruminants and nonruminants. Varieties that form large biomass, similar to rye, can be and are grazed, or harvested for silage or hay and straw. Triticale grain has nutritional value like wheat but with slightly more lysine amino acid. Triticale as a feed grain with good essential amino acid balance, minerals and vitamins is primarily included in livestock diets especially as an energy source. Depending on the type of domestic animal and meal, triticale can be used in significant percentage. The advantage of triticale over other cereals is that it has higher yields, a faster spring growth, and a longer mowing time as a green animal feed, than for example rays or oats. Because of all these advantages, triticale is suitable for planting especially in developing countries.

The antioxidant stability of minced pork treated with thyme and oregano essential oils (EOs) was determined. Minced pork containing different concentrations (0%, 0.3%, 0.6%, or 0.9%) of thyme (TEO) or oregano essential oil (OEO) and packaged under vacuum or modified atmosphere (MAP) (30%O2/50%CO2/20%N2) was evaluated within 15 days of refrigeration (3 ± 1 °C) storage. EOs were examined for scavenging capacity toward 2,2‐diphenyl‐1‐picrylhydrazyl, nitric oxide radicals, and hydroxyl, and inhibition of lipid peroxidation and ferric ion reducing antioxidant power (butylated hydroxytoluene was used as positive controls). The order of antioxidative effectiveness was as follows: butylated hydroxytoluene > OEO > TEO, with significant differences between agents (P < 0.05). Lipid oxidation in meat was determined by monitoring malondialdehyde (MDA) formation and lipolysis was assessed by measuring the acidity index immediately and after 3, 6, 9, 12, and 15 days of storage. EOs significantly (P < 0.05) increased the stability of minced pork with respect to lipid oxidation compared with the control, and the antioxidative effect was dose‐dependent. Moreover, vacuum packaging resulted in mince with significantly lower oxidation and lipolysis levels than modified atmosphere packaged mince (P < 0.05). The results demonstrate that both EOs examined effectively reduced lipid oxidation in raw pork mince after 2 weeks’ storage. Practical Application The natural food preservatives market is growing rapidly, as is high demand for organic foods. These results are likely to be of interest to the scientists, researchers, and persons who work in the meat industry. Results and discussion can contribute to a better understanding of antioxidative properties of essential oils in food model. Furthermore, no study has reported the effect of these MAP on pork oxidative stability.
