Insect-containing products are gaining more space in the market. Bakery products are one of the most promising since the added ground insects can enhance not only the nutritional quality of the dough, but technological parameters and sensory properties of the final products. In the present research, different amounts of ground Acheta domesticus (house cricket) were used to produce oat biscuits. Colour, hardness, and total titratable acidity (TTA) values were measured as well as a consumer sensory test was completed using the check-all-that-apply (CATA) method. An estimation of nutrient composition of the samples revealed that, according to the European Union’s Regulation No. 1924/2006, the products with 10 and 15 g/100 g cricket enrichment (CP10 and CP15, respectively) can be labelled as protein sources. Results of the colour, TTA, and texture measurements showed that even small amounts of the cricket powder darkened the colour of the samples and increased their acidity, but did not influence the texture significantly. Among product-related check all that apply (CATA) attributes, fatty and cheesy flavour showed a significant positive effect on overall liking (OAL). On the other hand, burnt flavour and brown colour significantly decreased OAL. OAL values showed that consumers preferred the control product (CP0) and the product with 5 g/100 g cricket enrichment (CP5) samples over CP10 and rejected CP15.

In this work, 10 processing type Hungarian tomato gene bank accessions were investigated in a 3-year open-field experiment together with three commercial varieties for quantifying the genotype × environment interaction for their total soluble solids, total acid, dry matter, lycopene, total polyphenol content and antioxidant activity. Results showed remarkable differences of accessions in phytonutrient content over the 3 years (environments). Genotype main effect plus genotype × environment interaction biplots were created for the visualization of the best performing samples and of their relation to a theoretical best variety. Obovate fruit-shaped accessions (especially RCAT031257 and RCAT060349) reached outstanding nutritional results in every environment. According to extremities in weather conditions, two landraces (RCAT060348 and RCAT060349) with higher drought tolerance, and two (RCAT031257 and RCAT029837) less prone to excessive rainfalls were identified. The results can contribute to the enrichment of tomato nutritional phenotypic data banks, facilitating the utilization of gene bank accessions in genomic studies.

At both global and national levels, COVID-19 caused huge changes both in politics and economics, including the agricultural sector and the food industry, from producers, manufacturers, and traders to consumers. Since March 2020, many restrictions and protective measures were introduced worldwide, which only began to be relaxed in the last weeks of spring 2021 as the number of people vaccinated against the coronavirus increased in Hungary. The aim of this study was to investigate the attitudes of Hungarian consumers toward food purchases during the COVID-19 pandemic, in terms of safety. The research was based on the purchase of bakery products, which are basic food products and are most often found in an unpackaged form in Hungarian stores. The BimiLeap® study, a revolutionary tool for uncovering people’s minds, was completed by 125 participants, gathered by a snowballing technique. There were no significant differences among consumers’ attitudes based on the traditional socio-demographic descriptors; however, the mindset-based classification was able to differentiate significantly. The three identified mindsets covered people who themselves consider bakery products, the purchase method, and being in the store as the highest risk of a potential COVID infection.

Plant genetic resources (PGRs) serving as a wide genetic pool of tomato germplasm can provide a solid base for recent breeding efforts to increase consumer acceptance towards the taste and the phytonutrient properties of novel tomato varieties. Old varieties and landraces were abandoned by producers due to unfavorable phenotypic characteristics; however, their high adaptability and nutritional properties are inevitably valuable. This study aims to investigate the impact of open-field vs. protected production on various bioactive compound parameters and on the antioxidant status of seven indeterminate-type tomato PGRs in an organic production system for two years (2015–2016). Genotype main effect plus genotype × environment interaction (GGE) biplots were created for visualizing the which-won-where concept of the PGRs investigated. The GGE analysis revealed that the phytonutrient content of certain PGRs is less dependent on location and more influenced by differences in microclimatic conditions. “Balatonboglár”, “Mátrafüred” and “Fadd” PGRs performed better in a polytunnel, while Tarnaméra provided better results in an open field. “Máriapócs” and “San Marzano” showed a relative independence from production location in terms of their measured phytonutrient values. These findings enrich the nutritional datasets of tomato landraces, which support the in situ conservation and utilization of PGRs in breeding programs.

Polymorphisms of TAS2R38 gene responsible for bitter taste perception elicit a bimodal receptor response in the population upon the detection of phenylthiocarbamide and 6-n-propylthiouracil, respectively. Genetic differences in sensitivity to phenylthiocarbamide and 6-n-propylthiouracil may affect body composition, food preferences, and frequency of consuming different food types. To date, no publication has been published in Hungary on the joint study of these factors. The aim of the present research is to find correlations between phenylthiocarbamide taster status and body composition, and the frequency of consumption of different bitter-tasting foods. In the study, a taster status survey of participants (n = 170), a bioimpedance-based body composition analysis (n = 96) and completed a food frequency questionnaire of bitter foods (n = 170) were conducted. Descriptive statistical methods, cross-tabulation analysis, multiple correspondence analysis, and Mann-Whitney test were used for data analysis at 5% significance level. The proportions of the taster and non-taster categories proved to be the same as reported by international literature (70%/30% respectively). There were no significant correlations among taster status and the other examined parameters, however, based on the multiple correspondence analysis, the observed trends are in accordance with the international literature. There were significant correlations among gender, body composition and some variables describing food preference. Based on the literature data and our own results, there can be a relationship between genotype and body composition, and genotype and food choice. Further analyses with large-sample size and representative research are needed to substantiate these assumptions.
