PurposeThis study investigates the relationship between buyers’ psychological antecedent and repurchase intentions in online group buying. Considering and evaluating pre-purchase, the authors measure the buyers’ overall experience of online group buying through their perceived value (PV) and risk. This study examines the influence of PV and perceived risk (PR) on positive electronic word-of-mouth (eWoM) communication and repurchase intention in online group buying.Design/methodology/approachThe authors verify the research model using SPSS and the structural equation modeling-partial least square (SEM-PLS) to analyze 839 convincing respondents. This quantitative research provides insights into online group buying, including the food industry.FindingsThe results demonstrate that the buyers’ PV of online group buying enhanced positive eWoM communication and repurchase intention. The willingness of buyers to spread positive eWoM indicates their recognition and satisfaction with a product or brand. Thus, they have the behavioral intention to repurchase in online group buying. The study found that while positive eWoM communication significantly impacts repurchase intention, PR negatively affects PV. The research provides theoretical and practical implications at the end of the study.Research limitations/implicationsThis study has some limitations. First, the study only used PV and PR to measure consumers’ considerations and evaluations of the initial stage in the consumer decision journey. Future studies can include more dimensions that may further affect these considerations and assessments to verify the research model. Second, the study only used positive eWoM communication to measure the “enjoy-advocate-bond” of consumption and usage in the post-purchase stage.Originality/valueThe study proposes the sequential relationship in the psychological decision procedure of participating in online group buying and provides valuable managerial implications for managers operating online group buying on third-party platforms. The findings provide good knowledge for the food industry to stay connected with customers and develop their satisfaction.

PurposeIn a sector that needs to satisfy a fast-increasing population, advancements like cultivated meat and bio-circular economy are basic to sustain the industry and the society. As innovations are key for economic and social progress, it is crucial to understand consumers' position on this matter.Design/methodology/approachBased on text data mining, 7,030 tweets were collected and organised into 14 different food-related topics. Of the total, 6 of these categories were positive, 5 were negative and 3 were neutral.FindingsIn total, 6 categories related to food technologies were positively perceived by Twitter users, such as innovative solutions and sustainable agriculture, while 5 like the virtual dimensions of the industry or crisis-related scenarios were negatively perceived. It is remarkable that 3 categories had a neutral sentiment, which gives ground to improvement before consumers have a negative opinion and consequently will be more complicated to change their minds.Originality/valueTechnological innovations are becoming predominant in the food industry. The SARS-CoV-2 pandemic has made the sector improve even faster. Traditional methods needed to be substituted and technologies such as robots, artificial intelligence, blockchain and genetics are here to stay.

The genus Hyssopus is widespread in central Asia, East Mediterranean, and Mongolian areas. It has six main species which are used as herbal remedies, such as Hyssopus officinalis which is used as a condiment and flavoring agent in food industry. The other five species are H. ambiguus, H. cuspidatus, H. latilabiatus, H. macranthus, and H. seravschanicus. Its species are used in the treatment of various ailments such as cold, cough, loss of appetite, fungal infection, and spasmodic condition. Its constituents especially essential oils are popularly used as an additive in beverages, foods, and cosmetics. The volatile constituents are used for aroma in the food industry, cosmetic industry, and household products. The important active constituents in its essential oils are β-pinene, pinocamphone, isopinocamphone, and other terpenoids. Hyssopus genus is also bundled with other secondary metabolites including flavonoids luteolin, quercetin, apigenin, and their glucosides, as well as phenolic compounds including ferulic, p-hydroxy-benzoic acid, protocatechuic acid, chlorogenic, and caffeic acid. Combinedly, the extracts of Hyssopus are reported to have potential antiviral and antifungal activities proven using in vitro studies, whereas in vivo investigations have reported the crucial role of Hyssopus extracts in plasma membrane relaxation, cytotoxic, and sedative effects. This plant is believed to be relatively safe at levels commonly used in foods; nevertheless, more studies are needed to determine the safety profile.

The purpose of this research was to studythe ability of whey protein concentrates (WPC) and whey permeate produced with ultrafiltration of cheese whey to rehydrate. The products studied were cheese whey concentrate witha PDM percentage of 80% (WPC-80), and cheese whey permeate, both produced under the conditions of the PJSC Dairy “Voronezhsky”.WPC-80 and the whey permeate dissolution processes were studied using microscopy. Water-impermeable hydrophobic layers were formed at the boundary, preventing water penetration into dry particles. The result was a higher dissolution timeforWPC-80 compared with whey permeate. When WPC-80 came into contact with water,it initially formed an obtuse wetting angle with a slow change over time. Whey permeate reached the equilibrium wetting angle more quickly. Quickreconditioning of WPC moisture content required avoiding capillary penetration of water, which created a turbulent liquid flow. The application of these ingredients in different food industry areas can reduce the costs for finished products, contribute to cost-effectiveness, increase the total production, and reduce environmental risks. Keywords: whey protein concentrate, whey permeate powder, water-wetting, dissolution

Introduction. Statistical methods of data processing and IT technologies make it possible to introduce new modern methods of hazard and risk analysis in food industry. The research objective was to develop new software that would link together various risk-related production data. Study objects and methods. The research featured food production company LLC Yug (Biysk, Russia) that specializes in functional products and various ready-made software automation solutions. The study also involved statistical methods, methods of observation, collection of primary information, sequential top-down development of algorithms, and the Java programming language. Results and discussion. Food producers have a registration procedure for inconsistencies and violations of permissible limits at critical control points. The authors developed a new software program that allows production line operators to enter data on downtime and other violations of the production process. The program makes it possible for managers to receive up-to-date reports on various criteria, identify violations, and select appropriate corrective actions. This ready-made solution automates the process of accounting and hazard analysis. The program was tested at LLC Yug with the focus on the time that operators and managers needed to register the problem, analyze the data, develop corrective or preventive measures, and apply them. Conclusion. The new software proved to be less time-consuming than standard procedures applied in food industry and made it possible to save the time that operators and managers spent on decision making and reporting.

Introduction. Contemporary food industry strives to increase the production volume of high-quality and biologically complete protein products. The Foodnet market also raised the demand for functional foods in Russia. The research objective was to develop a new functional curd product fortified with probiotic microflora. Study objects and methods. The study featured cow’s milk, skimmed milk, cream, whey protein concentrate Milkiland-WPC 80, pollen, glutamine, starter cultures DVS Danisco Probat 576 and Howaru Bifido ARO-1, buckwheat flour, and oat flour. The experiment included physicochemical, sensory, biochemical, and microbiological methods. Results and discussion. The milk-protein base of the curd product was produced in a GEA Westfalia KDB 30 curd separator. The research involved 15 and 20% cream with two different starter cultures. In case of 15% cream, Probat 576 Howaru Bifido appeared to be 1.66 times more active than ARO-1 Howaru Bifido, in case of 20% cream the result was even higher – 1.73 times. Probat 576 also demonstrated a better active acidity, i.e. 5.5 after three hours, which was two hours faster than ARO-1. Mathematical modeling revealed the positive effect of buckwheat and oat flour on the cream fermentation process. Oat flour (5%) was the optimal prebiotic, while buckwheat flour added its color to the final product, thus spoiling its market quality. Conclusion. The new biotechnology for a curd product fortified with probiotic cultures can expand the range of functional products for sports diet.
