In recent decades, the food industry has been faced with new challenges, and it has had to develop new types of diets and produce new types of foods that can slow down the spread of chronic diseases. The aim of our research was to identify the characteristics of plant-based nutrition, based on international and Hungarian literature. The comprehensive analysis was performed based on the theoretical model called Theory of Planned Behavior, in the course of which the perceived and objective benefits of and barriers to the conversion to a plant-based diet were examined. According to our results, the main benefits of plant-based nutrition are its many factors associated with a reduction in risk of developing numerous chronic diseases. This is followed by benefits of well-being and satisfaction, followed by ethical and environmental benefits. The most commonly reported inhibitory factor of a vegetarian diet is the enjoyment of eating meat and the difficulty in giving up meat consumption. This is followed by health considerations, e.g., lack of various ingredients in foods. Convenience and taste factors are also important disincentives, as well as the irrelevant nature of some plant-based nutrition information sources. Besides, social barriers, negative discrimination, and negative effect on mental health associated with them can also be a hindrance, as can financial barriers. The classification developed during our analysis can serve as a relevant guideline for decision-makers, and also as a basis for further primary qualitative and quantitative research.

The proposed study aims to segment consumers based on a sustainable approach to the consumption of food. The shift in consumers’ attitudes towards more balanced food consumption can be one of the sustainability drivers for entire food chains and may result in more sustained energy usage in the whole food chain and implementation of farm to fork strategy to the practice. We considered consumers’ attitudes as a multidimensional construct. Under this assumption, we asked respondents a series of questions related to the cognitive, behavioral, and affective components of an attitude. Data were collected from a market survey run among 433 consumers. We identified three consumer segments. The “Doers” segment exhibits sustainable behavior to a greater extent than the others. At the same time, they have less knowledge about the concept of food sustainability while the affective dimension was developed on an average level. The “Conscious” segment had well-developed cognitive and affective dimensions (which might indicate their openness to the information about sustainability positive feelings), however, it was not reflected in their behavior. Finally, the “Reluctant” segment, did not show a sustainable attitude towards food consumption in any of the analyzed dimensions. Answering the question of how common sustainable attitudes are may help in determining the market potential and in developing product and promotion strategies.

Food losses and waste are associated with inefficient use of agricultural land, water and other resources and agricultural raw materials. Reducing the scale of food wastage is one of the most urgent challenges for food system operators, starting from agriculture to food consumption in the households. This is all the more urgent as food insecurity has deepened during the COVID-19 pandemic. There are few studies on how to reduce food losses in food processing sectors, as most researchers focus on the demand side of the market, especially within household consumption. To fill the knowledge gaps related to the inefficient production system in the baking and confectionery industry (BCI), research was conducted to estimate the scale of losses in BCI in Poland, determine their causes and assess the risk of their occurrence, identify retrieve points (RP) and ways of reducing and preventing losses. Two research methods were used. Quantitative data were collected using an Internet survey method on a sample of 48 bakeries. The qualitative data was provided by 5 individual in-depth interviews with experts from the surveyed industry. The results showed that the total scale of losses in Polish BCI reached 2.39% (in 2017) and 2.63% (in 2018) of the weight of manufactured products. The loss analysis was presented within respective sections of production: raw materials magazine (RMM), production section (PS), final product magazine (FPM), final product transport (FPT). The highest loss level was reported for PS—1.56% (2017), 1.85% (2018). Additionally, 12 loss risks and nine main cause categories were identified. Potential 6 retrieve points (RP) during the baking processes were indicated: making and handling intermediate products and dough; portioning and forming of dough, baking, customised packing, shipping (storage), transport by own fleet. The type of risk, the cause of losses, their consequences, and manners of preventing losses were specified for each RP. Being the first study of this kind in Poland, its results are key to build a road map for further researches focused on reduction of food losses, more sustainable management of resources in BCI. It might contribute to corporate social responsibility and value co-creation.

Reducing food wastage is one of the challenges in achieving global food security and transforming current food systems. Since human nutrition is closely dependent on cereal production, research was undertaken aimed at understanding the food losses in the baking and confectionery industry (BCI) in Poland, in particular at determining the volume, reasons and ways of reducing losses, identifying possibly all of the reasons for losses in BCI using the Ishikawa 5M + 1E diagram and determining the level of significance and probability of risk of food losses in the analysed sector. Two research methods were used. Quantitative data were collected using the mass balance method from five businesses that served as case studies. Qualitative data were collected through individual in-depth interviews with 17 industry experts. The companies’ average daily losses ranged from 0.8 to 6.4 tons, representing 9.7 to 14.4% of production volume, including 10.4–13.4% of bread losses and 6.8–24.4% of fresh pastry losses. The highest losses were generated by transport departments and these were exclusively retail returns. Following the Ishikawa concept, 31 primary and 94 secondary reasons for food losses were identified. Using the probability of loss risk, a toolkit for loss prevention and mitigation across all departments within businesses (raw materials magazine, production section, final product magazine and final product transport) and a set of horizontal tools were identified, including specialised training for employees and activities in several areas, e.g., technical status and production technology, organisation and planning, logistics and sales and cooperation with retail. This study, conducted in Poland, offers valuable results for developing programmes and strategies to prevent and manage food losses in BCI. Many of the solutions proposed in both toolkits can bring economic benefits without involving additional high costs.

Barley (Hordeum vulgare L.) is an annual plant cultivated in spring or autumn. Currently, over 70% of the cultivated barley grains are utilized for preparing fodder, while the rest is used for the production of malt and cereals in the food industry. The purpose of the present work was to evaluate the content of bioactive compounds, antioxidant potential, and cholinesterase inhibitory effect of the aqueous extracts of juvenile barley leaves. It was found that the barley cultivars differed in their content of the determined phytochemicals as well as their antioxidant potential and cholinesterase-inhibitory activity. The water extracts of young barley leaves contained phenolic acids as well as quercetin, rutin, and kaempferitrin. The extracts showed a higher inhibitory effect on 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) than on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals. Based on the aqueous extracts analyzed, we found that winter cultivars were characterized by the highest iron-chelating activity. Furthermore, barley extracts showed a stronger inhibitory effect against acetylcholinesterase compared to butyrylcholinesterase. The results of the present work indicated that barley cultivars differed in their germination process. Among the tested samples, the highest cholinesterase inhibitory activity was shown by the Basic variety.
