Dielectric barrier discharge (DBD) atmospheric plasma treatment is an innovative non‐thermal food processing technology. There is an abundant body of research on the effectiveness in inactivation of foodborne pathogens on fresh fruit and vegetable produce with atmospheric air DBD plasma. However, studies that disclose plasma interactions with fruit or vegetable juices are scarce in number to the knowledge of the author. Color changes of orange and carrot juice blend due to atmospheric air DBD plasma treatment have been examined to estimate the extent of juice changes after treatments at varying durations of 5 s,15 s, and 30 s. Results indicate potentiality of cloud loss reduction, while treatments can cause minor degradation of color attributes. However, browning of treated samples was not observed. The influence of this new non‐thermal treatment on measured properties of orange and carrot juice blend shows promising results which need to be further confirmed and established. Practical applications The work described in this research offers an innovative treatment of orange and carrot juice blend with atmospheric air DBD plasma. This article assesses the suitability of atmospheric air DBD plasma to be used in orange and carrot juice blend, and its effects on color attributes. The results indicate the potential of treatment as a browning inhibitor in orange and carrot juice blend during processing which could be of practical industrial relevance.

This paper presents relationship between the rheological properties of dough and individual polymer swelling properties in wheat flour mill streams. The swelling properties were measured by applying the Solvent Retention Capacities (SRC) tests. Significant correlation coefficients were determined for certain rheological parameters. In an effort to extract additional insights from the properties measured, a multivariate analysis was used to develop relationships between the studied parameters. To determine relevant relationships among the parameters, the data exploration step by the Principal Component Analysis was performed. Then, multivariate Partial Least Squares Regression (PLSR) models were developed, to predict certain empirical rheology parameters based on the SRC parameters. The processing of experimental data indicated the possibility of using SRC parameters for predicting rheological properties in conjunction with a suitable mathematical model. The presented approach may be useful for rapid prediction of wheat flour mill streams characteristics and for optimization of the end-flour performances.

Cereals, nuts and spices are foods that are used in the daily human diet. According to FAO the average consumption of foods of vegetable origin in people's diet is increasing. Due to inadequate conditions during storage of foods of vegetable origin, there is possibility of contamination by mold that produces mycotoxins. Since the intake of these products in organism has been increased, there is a risk of exposure to mycotoxins and their harmful effect on the consumers' health. The aim of this study was to determine the presence of aflatoxin B1 in products of vegetable origin (cereals, nuts and spices). Aflatoxin B1 was determined by enzyme-imunochemical method (ELISA), using commercial kit. 38 samples were tested. In 25 analyzed samples, the content of aflatoxin B1 was higher than 1 µg/kg (1 µg/kg is limit of detection). Out of the total number of tested samples, in 18 samples the content of aflatoxin B1 was determined higher than the allowed amount for this product group by the current regulations (2 µg/kg for cereals, 2 µg/kg for nuts and 5 µg/kg for spices).

By the application of processes of stabilization through drying,separation of seed and grinding of remaining placenta dietaryfiber-rich powdered product was obtained from pepper (Capsicumannum L.) processing waste. Effects of dosing of pepper placentabasedsupplement (1, 2 and 3%) on farinograph, extensographand amylograph parameters, as well as test baking, wereconducted in this study.Addition of pepper placenta-based supplement resulted in anincrease of farinograph water absorption in obtaining of darkerand more intensively colored bread crust and in smaller and moreevenly distributed pores of breadcrumb. It also inhibited thefirming of breadcrumb during bread shelf life. The main negativeeffects of the application of placenta-based supplement were theincrease of dough resistance and the decrease of breadcrumbcohesiveness.
