The present article aimed to study the effects of four selected concentrations (1%, 2%, 5%, and 10%) of apple pomace powder (APP), obtained from juice production, on the nutritional value and selected physico-chemical, antioxidant, and sensory properties of wheat bread. We have found that the ash and total carbohydrate contents, total polyphenols content, and antioxidant activity of the supplemented bread loaves were markedly higher (p < 0.05) as compared to the control ones. On the other hand, values for protein and fat contents and loaf volume in APP-containing bread samples were statistically lower (p < 0.05). Finally, sensory evaluation revealed no significant differences in all tested attributes between the investigated groups of bread samples. The current results suggest that 10% APP addition appears to be an attractive ingredient applied to bread formulation to obtain a bakery product with high nutritional value and required qualitative and sensory properties. In such a manner, apple pomace as by-products from apple juice processing can be efficiently utilized in an eco-friendly way by the food industry to decrease unnecessary waste and environmental pollution.

Cereal (1,3)(1,4)-β-d-glucans, known as β-d-glucans, are cell wall polysaccharides observed in selected plants of grasses, and oats and barley are their good natural sources. Thanks to their physicochemical properties β-d-glucans have therapeutic and nutritional potential and a specific place for their functional characteristics in diverse food formulations. They can function as thickeners, stabilizers, emulsifiers, and textural and gelation agents in beverages, bakery, meat, and extruded products. The objective of this review is to describe the primary procedures for the production of β-d-glucans from cereal grains, to define the processing factors influencing their properties, and to summarize their current use in the production of novel cereal-based foods. Additionally, the study delves into the utilization of β-d-glucans in the rapidly evolving field of nanotechnology, exploring potential applications within this technological realm.

Drought is one of the most important factors that influences plant morphology, biochemistry, and physiology, and finally leads to the decline in crops productivity and seed quality. Climate change, severe changes in water availability together with thermal stresses environment coincide with increasing human population, and to reveal sustainable solutions it is necessary to understand: i) how cereals react to drought, ii) how the tolerance mechanisms are exhibited by the genotype, and iii) which approaches enable to increase the tolerance of crop species against limited water availability. Especially in cereals as in high-quality food sources, it is important to reveal the adaptation mechanisms to rainfall dynamics on arable land and to the prolonged period of drought. This review summarizes current knowledge on the impact of drought on cereals, the mechanisms these crops utilize to cope water scarcity and survive, and the most efficient approaches to improve their drought tolerance.

Improving the micronutrients in food has become an important field of the Second Green Revolution. In recent years, minor bioactive compounds such as polyphenols, pigments and carotenoids, have attracted more and more interest from both researchers and food manufactures as health-promoting and disease-preventing effects in both in vitro and in vivo studies. One of plant pigments, wheat anthocyanins as plant phenolics are increasingly attractive as natural compounds positively affecting consumer´s health and condition moreover wheat is staple food source consumed usually daily. For a purple, blue, or red colour of wheat seed are responsible glycosylated cyanidins, delphinidins, malvinidins, pelargonidins, petunidins, and peonidins located in aleurone layer or pericarp, respectively. Other than white seed colour is not natural for common hexaploid wheat but this trait can be introduced from donors by aimed breeding programs. The way of wheat anthocyanins to provide positive effects for consumer´s physiology is limited due to their specific occurrence in seed parts usually removed during grain milling practice and lower stability during processing to food

Oil content, fatty acids profile, acid and saponification values of poppy seeds grown on two localities of the Slovak Republic were evaluated in the study. Statistically significant effects of locality, genotype and their interaction (P < 0.05) for numerous descriptors were proved by non-parametric tests. Results confirmed that variation in the analysed parameters was influenced by the colour of seeds. Ochre variety Redy contained the highest oil level in both localities (49.9 and 52.4%) and linoleic acid level (74.3 and 71.6%). White-seeded Racek and Albín had the highest acid value (2.8 and 2.4% of free fatty acids) and grey-seeded Malsar and blue-seeded Maratón contained the highest saponification value. Buddha, a high-morphine poppy variety, differed significantly in all monitored parameters. High negative interrelation between linoleic and oleic acids levels was observed. Oil content was positively correlated with linoleic acid and negatively with oleic acid. Weather conditions at the end of vegetation influenced the accumulation of oil and essential linoleic acid.
