Abstract
Purpose
Mango seed, an agricultural food (agri-food) waste obtained during mango processing is generally discarded and causes environmental stress. In the present study, mango kernel was processed into flour and incorporated into macaron formulation. This study aimed to investigate the antioxidant potential, physicochemical properties, and sensory qualities of macaron after substitution of almond flour (AF) with 0% (control, MC-0), 20% (MC-20), 40% (MC-40), 60% (MC-60), 80% (MC-80) and 100% (MC-100) (w/w) of mango kernel flour (MKF).
Design/methodology/approach
Sensory evaluation was conducted using a nine-point hedonic scale (n = 90 young adults) to evaluate the acceptance towards MC-0 (control), MC-20, MC-40, MC-60, MC-80 and MC-100 macaron shells (without mango-flavoured ganache). The most preferred formulated and control macarons were subjected to proximate analyses according to the methods of Association of Official Analytical Chemists for moisture, ash, and protein, and American Oil Chemists' Society for fat. Carbohydrate content was estimated by difference. Physical analyses such as colour, pH and water activity (aw) were performed using various instrumental techniques. Antioxidant activity of all macaron shell formulations was accessed using 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH-RSA). Sensory evaluation was repeated using a five-point hedonic scale to determine the acceptance of the most preferred macaron (with mango-flavoured ganache) among consumer panels of all age groups (n = 80).
Findings
The first sensory acceptance test revealed that macaron shell with 40% MKF substitution (MC-40) was the most preferred formulation among young adults aged 18–35 years old. Moisture and ash contents between MC-0 and MC-40 were found to be similar (p > 0.05), while significant differences (p < 0.05) were observed for the fat and protein contents. Antioxidant activity increased proportionally with increasing MKF substitution and exhibited significant improvement (p < 0.05) in MC-40. Approximately 93% of the panellists expressed their liking towards MC-40 in the second sensory acceptance test. Overall, this study demonstrated that 40% MKF substitution in macaron improved its antioxidant performance without compromising consumers' acceptance.
Originality/value
This innovative research features the incorporation of MKF in the development of an economical and healthier macaron. The results constitute industrial relevant findings pertaining to its application feasibility and nutritional properties. This research has contributed knowledge to the existing literature as well as benefitted food manufacturers to develop value-added products that could meet the needs and expectations of interested parties, including consumers, governmental organisations, health-cautious advocates and healthcare providers.

Abstract
Purpose
As a new communication paradigm, social networking sites (SNS) have boosted information diffusion and viral marketing. Prior researchers have identified various factors affecting information dissemination on SNS. However, they often focus on limited factors and there is a lack of an integrated theoretical framework that explains aspects of relevant factors. Besides, the research on the impacts of relationships on individual retweeting behavior is still controversial. The purpose of this paper is to propose a theoretical framework to systematically investigate the determinants of individual dissemination behavior on SNS based on the elaboration likelihood model (ELM). Moreover, the authors also examine the relative importance of those relevant factors.
Design/methodology/approach
The authors randomly selected 1,250 members of Twitter and crawled posts published by each member since he/she created the Twitter account using Twitter API. The authors processed the data to create panel data and tested hypotheses with the panel logit model.
Findings
Factors both on the central route and on the peripheral route of ELM have positive impacts on individual dissemination behavior. Among them, information receiver-related factor and relationships-related factors are the most influential. Contrastingly, source-related factors are the least influential. Furthermore, the authors find that social tie strength mediates almost 50 percent of the effect of value homophily on individual dissemination behavior.
Originality/value
The authors are the first to directly apply ELM to examine individual dissemination behavior on SNS. By integrating factors into the two information processing routes, They incorporate relevant factors into the model and systematically analyze their impacts on individual retweeting behavior on SNS. The research offers at least one explanation for the contradictory findings about the effect of homophily on individual sharing behavior in previous research. The authors propose new variables that gauge topical relevance and interpersonal value homophily on SNS.

Abstract
Purpose
A new business model online to offline (O2O) has emerged in recent years. Similar to many new models at an early stage, O2O has inconsistent definitions which not only inhibit its adoption but also poorly differentiate O2O from other existing business models. To resolve the two issues, the authors propose an approach of definition development.
Design/methodology/approach
To show the usefulness of the approach, the authors demonstrate the differences among O2O and other business models with the use of the distinctive definition and thereby evaluate adoption of O2O from a practical perspective and identify research directions from a theoretical perspective based on the differences.
Findings
The authors' proposed approach of definition development integrates the work of Tatarkiewicz (1980) and Nickerson et al. (2013). The approach generates a distinctive definition of O2O with important analytical dimensions which help decision-making of adoption of O2O.
Originality/value
The paper aims to make several contributions. First, on theoretical contribution, the authors confine the scope of O2O studies and facilitate accumulation of more coherent knowledge of O2O. The authors help O2O evolve from a “buzz word” of successful stories in real businesses to a more serious concept from an academic perspective. Second, from a practical perspective, the authors' definition provides business executives with critical evaluative dimensions for gauging the adoption of O2O. Lastly, from a methodological perspective, the proposed approach can be used in future to define an emerging concept in real life businesses.
