PurposeThe purpose of this study is to investigate the viability of probiotics, physicochemical and sensory properties of reduced fat synbiotic ice cream.Design/methodology/approachThe treatments were as follows: control was made by the addition of Lactobacillus salivarius NBIMCC 1589 and Lactobacillus crispatus NBIMCC 2451 (1:1). The treatments (T1, T2 and T3) were made with the addition of L. salivarius NBIMCC 1589 and L. crispatus NBIMCC 2451 (1:1) + 2% oat flour, 2% inulin and 4% oat flour + inulin (1:1). Physiochemical parameters (pH, moisture, fat, protein, fibre, ash, overrun, first dripping time and melting rate) were determined.FindingsThe ice cream with inulin and oat flour had lower moisture content, which was recorded 70.41, 69.88 and 68.82% for T1, T2 and T3, respectively. While the protein, fat and ash content of treated samples increased. The highest acidity (0.43%) was recorded in T3. The overrun increased by around 43% in T3 compared with control. The viable counts of probiotics were significantly (p = 0.05) decreased by two or three log cycles. Finally, T3 received the highest sensory score, which could be due to the combination between oat flour and inulin.Originality/valueA novel ice cream was produced using a combination of inulin and oat flour, which enhanced the viability of added probiotics. Reduced fat synbiotic ice cream was a good carrier for probiotics, which facilitates the production of healthy dairy products.

Purpose Among soy products, soy ice cream with neutral pH, high total solids contents and prebiotic oligosaccharides is an appropriate vehicle for probiotics. The purpose of this paper is to survey soy ice cream as a carrier for the efficient delivering of Lactobacillus casei, or L. casei. Design/methodology/approach Probiotic soy ice cream containing L. casei was produced via the powder of soy milk. The physicochemical and organoleptic properties of the product were assessed. Also, the viability of L. casei was surveyed over a 180-day period of storage at −25 °C. Findings The density characteristic of probiotic soy ice cream demonstrated a significant rise (P < 0.05). The result of the viability analysis showed significant alterations in the number of probiotics in this product after freezing and throughout the 180-day period (P < 0.05). The most noticeable drop was seen throughout the first 60 days about 1.83 logs after that the trend of survival of this probiotic strain leveled off over the next 120 days. Also, no significant differences were found in the organoleptic properties of both ice creams. Originality/value Soy ice cream with prebiotic elements protected the growing and activity of probiotic bacteria. The results showed that L. casei is a good probiotic for soy ice cream.

The Ideal

Purpose Carob has been proposed as a healthy, stimulant-free alternative to chocolate in frozen desserts. In order to make carob a viable and attractive alternative, food producers need to know how it interacts with sweeteners and frozen dessert dispersion matrices. The purpose of this paper is to find the optimal sweetener concentration in three plant-based frozen desserts and carob-flavoured milk dispersion matrix ice cream. Design/methodology/approach The ideal sucrose concentrations (per cent) were determined through an affective test using the “just-about-right” scale for carob-flavoured frozen desserts made with cashew nut, coconut and soy beverage, as well as milk dispersion matrix. The sweetness equivalence of artificial sweeteners relative to sucrose was determined by the magnitude estimation test. Findings The authors identified the concentrations of sucrose, stevia and sucralose that produced ideal sweetness in carob-flavoured frozen desserts. Concentrations for soy-based frozen desserts differed from the other dispersion mediums tested. Plant-based frozen desserts exhibited a higher ratio of sweetening power of stevia and sucralose to sucrose compared to milk-based ice cream by a factor of 1.18 and 1.14, respectively. Originality/value This study undertook a comprehensive survey of a dairy-free and chocolate-free alternative to chocolate ice cream and found new sweetener interactions with dispersion matrices in carob-flavoured frozen desserts. The findings in this study can be applied in the development of carob-flavoured soybean-, coconut-, cashew nut- and milk-based frozen desserts.

Purpose – The paper is devoted to develop the methodological technique for the implementation of competitive benchmarking in an industrial company in strategy of “the follower”. The paper aims to discuss these issues. Design/methodology/approach – In the research, a non-parametric methodology of efficiency analysis is used. To solve the problem of finding the best competitor, the author proposes to apply the method of free disposal hull (FDH). Findings – The proposed methodological technique for the implementation of competitive benchmarking in an industrial company in strategy of the follower enables to gradually develop and make informed strategic decisions that ensure the achievement of efficiency frontier and a leadership in its market segment. Research limitations/implications – The research is limited by a single industry (dairy products). This is explained by requirement of technology (product, service) homogeneity when using FDH model. Practical implications – By a case of 60 Ukrainian dairies, the paper demonstrates how the author can use the proposed technique in a practice and what steps the author should make to find company benchmark and improve the efficiency. It is possible to use the results of this research to make competitive benchmarking for the other industries. Originality/value – This paper adopts FDH model for competitive benchmarking and implementing the strategy of the followers. The proposed technique enables to improve the various activities of the analyzed dairies.

Food Safety Standards

Purpose – The purpose of this paper is to empirically examine how China's food safety standards affect agricultural trade in the case of dairy products. Design/methodology/approach – A gravity model is applied to quantitatively address the impacts of changing food safety standards in China in the case of its dairy imports. The paper considers the trade impacts of not only a specific hazard substance but also overall strictness of safety standards. Findings – The paper shows that changes in food safety standards of dairy products have no effect on China's dairy imports. The finding is not particularly surprising considering special characteristics of China's food safety standards. Given the fact that China's safety standards are relatively lower than that in its major exporters, the trade-impeding effect may not be substantial. Research limitations/implications – First, this study is unable to estimate the trade-enhancing and trade-impending effects separately. Second, the study does not account for a potential endogeneity issue associated with food safety standards. Originality/value – This paper contributes to the debate on how food safety standards affect trade by demonstrating that safety standards in developing countries like China can affect international trade differently from that in developed countries. Although results are specific to China's dairy imports, the explanations are applicable to food safety standards in other developing countries.

Purpose The purpose of this paper is to investigate how individuals perceive and react to the involuntary demotion of a co-worker in their organisation. Design/methodology/approach The authors draw on 46 semi-structured in-depth interviews (23 dyads) with co-workers of demoted individuals. Findings The findings suggest that an individual’s observation of the demotion of a co-worker has three stages: their perception of fairness, their emotional reaction and their behavioural reaction. The perception of fairness concerned issues of distributive, procedural, interpersonal and informational justice. The emotional responses identified were feelings of disappointment/disillusion, uncertainty, vulnerability and anger. Finally, the behavioural reactions triggered by their emotional responses included expressions of voice, loyalty, exit and adaptation. Originality/value Perceptions of (in)justice perpetrated on others stimulate emotional and behavioural responses, which impacts organisational functioning. Managers should therefore pay attention to the way a demotion is perceived, not only by those directly concerned, but also by co-workers as observers.

Purpose The purpose of this paper is to understand in-depth how consumers create value in their lives using WhatsApp, the leading mobile instant messaging (MIM) application. Design/methodology/approach The study adopts the perspective of customer-dominant logic (CDL) and uses a qualitative multimethod design involving 3 focus groups and 25 subsequent in-depth interviews. The research setting was Ecuador, a Latin American country. Findings Analysis and interpretation of the participants’ stories made it possible to identify and understand the creation of four types of value: maintaining and strengthening relationships; improving role performance; emotional support; and entertainment and fun. In addition, the present study proposes a conceptual model of consumer value creation as it applies to MIM. Practical implications Understanding the way consumers create value in their lives using MIM is important not only for organizations that offer MIM applications, but also for those companies that develop other applications for mobile phones or for those who wish to use MIM as an electronic word-of-mouth vehicle. Originality/value The current study is one of the first to address the topic of consumer behavior in the use of technologies from the perspective of CDL; this perspective enables an integrated qualitative vision of value creation in which the consumer is the protagonist.

Purpose The purpose of this paper is twofold: first, to understand data management challenges in e-maintenance systems from a holistically viewpoint through summarizing the earlier scattered research in the field, and second, to present a conceptual approach for addressing these challenges in practice. Design/methodology/approach The study is realized as a combination of a literature review and by the means of analyzing the practices on an industry leader in manufacturing and maintenance services. Findings This research provides a general understanding over data management challenges in e-maintenance and summarizes their associated proposed solutions. In addition, this paper lists and exemplifies different types and sources of data which can be collected in e-maintenance, across different organizational levels. Analyzing the data management practices of an e-maintenance industry leader provides a conceptual approach to address identified challenges in practice. Research limitations/implications Since this paper is based on studying the practices of a single company, it might be limited to generalize the results. Future research topics can focus on each of mentioned data management challenges and also validate the applicability of presented model in other companies and industries. Practical implications Understanding the e-maintenance-related challenges helps maintenance managers and other involved stakeholders in e-maintenance systems to better solve the challenges. Originality/value The so-far literature on e-maintenance has been studied with narrow focus to data and data management in e-maintenance appears as one of the less studied topics in the literature. This research paper contributes to e-maintenance by highlighting the deficiencies of the discussion surrounding the perspectives of data management in e-maintenance by studying all common data management challenges and listing different types of data which need to be acquired in e-maintenance systems.

Purpose The purpose of this study is to develop a profile of whistleblowers and to determine whether whistleblowing legislation would encourage those individuals to bring to light some illegal or unethical behaviour that otherwise would remain in the shadows. Design/methodology/approach Having identified whistleblowing correlation, a survey was carried out in Cyprus of actual whistleblowers and could-have-been whistleblowers. Findings Males between 46 and55 years of age, regardless of whether they have dependents or hold senior positions in organizations are significantly more likely to blow the whistle. However, could-have-been whistleblowers did not go ahead because they felt that the authorities would not act on their information. Research limitations/implications Because of the sensitive nature of the research topic and the fact that only whistleblowers or intended whistleblowers could participate in the study, the sample size is limited as a result. This, in turn, limits both the number of respondents in each category (actual and intended) as well as constrains the statistical analysis that could be carried out on the data. Practical implications It remains to be seen whether EU Member States shall implement the European Directive 2019/1937 on the protection of persons who report breaches of Union Law, in its entirety by the due date, namely December 2021. Originality/value This study provides a literature review of whistleblowing and reports an original survey against the backdrop of the European Directive.
