Abstract

Purpose

The purpose of this paper is to evaluate effects of simultaneous supplementation of milk protein concentrate (MPC) as texture modifier and microencapsulated Lactobacillus paracasei (L. paracasei) (entrapped in gellan–caseinate) on physico-chemical, sensorial and microbial characteristics of yogurt during storage time.

Design/methodology/approach

L. paracasei cells were encapsulated through unique pH triggered gelation technique using combination of sodium caseinate-gellan gum as protective shell material. MPC was also used to improve physico-chemical indices of probiotic yogurt at different levels (0–3 percent).

Findings

The results showed that yogurt samples containing encapsulated L. paracasei showed lower post-acidification and higher viability. Samples containing encapsulated L. paracasei showed less syneresis amount, due to possible hydration of shell material, also application of MPC could reduce this attribute during storage time. The numbers of probiotic bacteria were remained above the recommended therapeutic minimum throughout the samples.

Practical implications

The findings suggest a practical ingredient in probiotic dairy product. Simultaneous usage of this kind of encapsulation via MPC enhanced sensorial and physical properties of probiotic yogurt while of no reduction in viable counts survival.

Originality/value

This study revealed usage of microcapsules of L. paracasei prepared by the gelation of sodium caseinate-gellan gum could be a suitable manner for delivery of probiotics in fermented dairy products like yogurt.

Abstract

Purpose

The quality of probiotic yogurt which is remarked as a healthy, therapeutic and nutritious food product strongly depends on starter types and their compositions; however, the choice of starter culture affects the taste, aroma and quality of the final product. Through this study, to obtain favorable quality attributes of probiotic yogurt, a mixture of two thermophilic/mesophilic starter cultures (YC- 350/YC- X16) was applied for fermentation.

Design/methodology/approach

The effects of starter mixture, probiotic Lactobacillus paracasei and storage time on quality indices, such as apparent viscosity, water holding capacity, syneresis, post acidification rate and probiotic viability (L. paracasei), were assessed through using a combined (mixture-process) statistical design.

Findings

The results revealed that changes in viscosity and syneresis depend on the amount of YC- X16. Acidification rate was more pronounced at higher levels of YC- 350 (1.22 per cent) in comparison to that in YC-X16 (1.08 per cent) during storage time. With respect to probiotic viability, L. paracasei count was more than 107 cfu/mL during refrigerated storage time. Moreover, a promotive effect of YC- 350 on L. paracasei proliferation was observed in this study.

Originality/value

The favorable yogurt, from qualitative aspects, was manufactured at 75:25 per cent ratio of YC- X16:YC- 350 in probiotic type yogurts. Therefore, the use of mixed starter cultures developed textural properties of probiotic yogurt beside L. paracasei survival.

Abstract

Purpose

Considering the importance of innovation in organizations and the formation of innovative behaviors (IBs) in the life of the organization, the authors study the effect of moderating social capital (SC) and gender in the link between knowledge sharing (KS), including sharing best practices and sharing mistakes with IB.

Design/methodology/approach

In this research, a random sampling method was used. A questionnaire was completed by 310 employees working in five prestigious companies in the energy sector located in Mashhad province, Iran.

Findings

The findings of the research indicate the influence of KS on IB. Also, SC moderates the effect of KS on IB. However, the moderating effect of gender was not significant, sharing best practices more likely to lead IB in women. Moreover, the men are more likely to show IB as they share their mistakes in comparison with women.

Originality/value

This research aims to break the black box on the link between employee KS and his/her own innovativeness, which is not frequently investigated. To the authors' best knowledge, there is a lack of deep empirical study that has delved into analyzing the impact of gender-groups and SC on this relation.

Abstract

Purpose

The purpose of this paper is to explore empirically how the two kinds of strategic orientations including export market orientation (EMO) and technology orientation (TO) predict innovation performance (IP) and export performance (EP), by investigating the mediation effect of IP and the moderation effect of external network (EN).

Design/methodology/approach

The statistical population of this research is the food and agricultural products exporting firms which participated in the 26th International Agrofood Exhibition in Tehran, Iran. The sample of 296 managers filled out questionnaires using systematic random sampling methods. Structural equation modeling was used to analyze the data.

Findings

Results demonstrate that the increase of EMO and IP is related to a rise in EP. Furthermore, the research finds that IP is a partial mediator in the link between EMO and EP. Finally, the moderation impact of the external networks in an association between TO and IP is supported by the data.

Originality/value

This study is one of the limited number of studies to consider the mediation impact of innovation performance in the relationship between EMO and EP, and it is actually the first study, to the best of the authors’ knowledge, to investigate the moderating impact of EN in the relationship between TO and IP in the context of one developing country.

Abstract

Purpose

This study explores the effects of competitive intensity and innovation orientation on export outcomes, including export entrepreneurship (EE) and export performance (EP), and determines the direct and moderating impact of corporate social responsibility (CSR) among exporting agricultural and food (agri-food) small and medium-sized enterprises (SMEs) in Iran.

Design/methodology/approach

Using systematic random sampling, 296 firms participating in the international food and agricultural industries exhibition filled out a questionnaire. Smart PLS3 software was used to analyze the data.

Findings

The competitive intensity has positive effects on export entrepreneurship of Iranian agri-food SMEs. Additionally, innovation orientation, CSR and EE positively impact EP. However, the moderating impact of CSR on the relationship between innovation orientation and EP was not supported by data.

Originality/value

The current study enriches the existing knowledge in international business in the specific setting of exporting agri-food SMEs operating in a developing economy.

Abstract

Purpose

This paper investigates the impact of various leadership styles on the professionalization and subsequent performance of family businesses.

Design/methodology/approach

Using a survey method and employing a partial least squares approach to structural equation modeling, we tested our model and analyzed the collected data based on the responses of 216 managers in Iran.

Findings

Our research demonstrates that professionalization mediates the relationship between leadership style and performance. Moreover, our findings show that the participative leadership style is the most effective option for family businesses seeking to achieve professionalization and improve performance.

Research limitations/implications

First, the sample used in this study was drawn from a single country, namely Iran. Second, although we adhered to established practices for measuring financial performance, future research could explore alternative dimensions of performance, including non-financial goals. Third, we did not investigate the impact of different leadership styles on each dimension of professionalization.

Practical implications

These findings provide valuable insights for family business managers seeking to adopt a suitable leadership style to achieve professional management and realize favorable outcomes.

Originality/value

Our study suggests that examining the potential impact of leadership styles on professionalization can provide clarity amidst mixed findings regarding the influence of professionalization on firm performance. Additionally, we challenge the oversimplified categorization of professionalization and argue for a multifaceted view, contending that professionalization comprises various dimensions acting concurrently and potentially mediates the effect of leadership styles on family business performance.

Abstract

Purpose

This study aims to investigate the effect of intangible capital (e.g. intangible investments and research and development (R&D) expenditures) on future profitability in an emerging economy and the moderating role of economic policy uncertainty (EPU) for companies listed on the Tehran Stock Exchange.

Design/methodology/approach

To this aim, information about 210 companies during 2014–2021 was collected. This study calculated EPU based on the inflation rate, interest rate, exchange rate and economic growth.

Findings

The results showed that both R&D expenditures and other intangible investments positively affect future profitability. Moreover, EPU decreases the positive effect of R&D expenditures and other intangible investments on future profitability. Hypothesis testing based on ordinary least squares and generalized method of moments regressions confirmed these results. This study emphasizes the urgent need to adjust how they operate the business during the COVID-19 pandemic.

Originality/value

The nature and degree of intangible assets and R&D expenditures in firms in emerging markets is an interesting area of research. However, empirical studies in this area have not led to any unanimous conclusion in emerging markets. Moreover, intangible assets and R&D expenditures become very important in the economy affected by the financial crisis and conditions of uncertainties. In light of the COVID-19 crisis, significant changes occurred at all levels and affected accounting-related issues, and the present study highlighted COVID-19. The findings of this research will not only help the managers of companies in developing countries but also, because of the dearth of similar research, they can help managers in developed countries and the global community.

Abstract

Purpose

There are different opinions about the quality and reputation of publications. Given that one of the ways to analyze the quality of journals and articles is citation indicators, the purpose of this paper is to compare the citation indicators of open access (OA), full subscription and hybrid journals and articles based on the Scopus in the field of library and information science (LIS) for a period of ten years (2004-2013).

Design/methodology/approach

The research population is all LIS journals and articles in LIS hybrid journals in Scopus. The data related to citation indicators (number of received citations, two years’ impact, Citescore [IPP] and H-index) were extracted from Scopus, Journal Metrics and SCImago and analyzed using descriptive and analytical statistics with SPSS and Excel.

Findings

The findings indicate that number of OA journals and articles were less than that of full subscription and hybrid journals. The average rate of all citation indicators in hybrid journals were more than that of OA and full subscription journals. However, in the level of articles, the average number of citations received by OA articles (15.6) was more than that of non-OA articles (2.25).

Originality/value

Unlike journals, OA seems to be an advantage for articles in LIS. LIS hybrid journals receive more citations than OA and subscription journals. Thus, the authors’ approach to publishing in OA, hybrid or subscription journals and the publishers approach to the publication type may also be influenced by the findings of the present study.
