Abstract

Purpose

The purpose of this paper was to evaluate the effect of pomegranate seed powder, grape seed extract and tomato powder on the quality characteristics of chicken nuggets during refrigerated storage.

Design/methodology/approach

The study was designed to evaluate the effect of pomegranate seed powder, grape seed extract and tomato powder on the storage quality parameters of chicken nuggets. The products were developed by incorporating optimum level of pomegranate seed powder (3 per cent), grape seed extract (0.3 per cent) and tomato powder (2 per cent) separately and were aerobically packaged in low-density polyethylene pouches and assessed for various storage quality parameters under refrigerated (4±1°C) conditions for 21 days of storage. The products were evaluated for various physico-chemical, microbiological and sensory parameters at regular intervals of 0, 7, 14 and 21 days.

Findings

A significant (p < 0.05) effect of pomegranate seed powder, grape seed extract and tomato powder was observed on the pH and thiobarbituric acid reacting substances (mg malondialdehyde/kg) values of the chicken nuggets. A significant (p < 0.05) effect was also observed on the microbiological characteristics, as the products incorporated with pomegranate seed powder, grape seed extract and tomato powder showed significantly (p < 0.05) lower values for total plate count, psychrophilic count and yeast and mould count during the period of storage. Coliforms were not detected throughout the period of storage. Significantly (p < 0.05) higher scores were observed for various sensory parameters of the products incorporated with pomegranate seed powder (3 per cent), grape seed extract (0.3 per cent) and tomato powder (2 per cent).

Originality/value

Pomegranate seed powder (3 per cent), grape seed extract (0.3 per cent) and tomato powder (2 per cent) successfully improved the oxidative stability and storage quality of the products during refrigerated (4±1°C) storage and may be commercially exploited to improve the storage quality of muscle foods without adversely affecting the sensory quality of the products.

Abstract

Purpose

The purpose of the present study was to evaluate the effect of tert-Butylhydroquinone (TBHQ) on the quality characteristics of low-fat Kalari, a hard and dry cheese. The products treated with TBHQ were assessed for various oxidative stability and storage-quality parameters.

Design/methodology/approach

Low-fat Kalari was prepared and treated with different concentrations of TBHQ (0, 200, 300 ppm) and aerobically packaged within low-density polyethylene pouches and assessed for physicochemical, microbiological and sensory characteristics under refrigerated (4 ± 1°C) conditions.

Findings

TBHQ showed a significant (p < 0.05) effect on the lipid stability, as the treated products exhibited significantly (p < 0.05) lower TBARS (mg malonaldehyde/kg) values for the entire period of storage. pH showed a significant (p < 0.05) decreasing trend, whereas titratable acidity followed a significant (p < 0.05) increasing trend with storage period in control as well as treated products. No significant (p > 0.05) effect was observed on the microbiological characteristics of the products, as TBHQ-treated products showed comparable (p > 0.05) values for total plate count, psychrophillic count and yeast and mould count. Significantly (p < 0.05) higher scores were observed for various sensory parameters of the treated products.

Originality/value

TBHQ successfully improved the storage quality of low fat Kalari during refrigerated (4 ± 1°C) storage and may be commercially exploited as an antioxidant in Kalari and other cheese like products.

Abstract

Purpose

The purpose of this paper was to explore the possibility of utilization of Ocimum sanctum Linn (Tulsi) leaf extract as a natural preservative in muscle foods. The products incorporated with Ocimum sanctum leaf extract were assessed for various oxidative stability and storage quality parameters.

Design/methodology/approach

The Ocimum sanctum leaf extract was incorporated at 300 mg/kg level in the formulation. Chicken sausages incorporated with Ocimum sanctum leaf extract along with control samples were aerobically packaged in low-density polyethylene pouches and assessed for lipid oxidation, physicochemical, microbiological and sensory characteristics under refrigerated (4 ± 1°C) conditions.

Findings

Ocimum sanctum leaf extract showed a significant (p < 0.05) effect on the lipid stability, as the treated products exhibited significantly (p < 0.05) lower thiobarbituric acid reactive substances (mg malonaldehyde/kg) and free fatty acid (% oleic acid) values in comparison to control. A significant (p < 0.05) effect was also observed on the microbiological characteristics of the products, as the treated products showed significantly (p < 0.05) lower values for total plate count, psychrophilic count and yeast and mould count. Significantly, (p < 0.05) higher scores were also observed for various sensory parameters of the treated products.

Originality/value

The paper has demonstrated the use of Ocimum sanctum leaf extract as a potential natural preservative, as it successfully improved the oxidative stability and storage quality of the products during refrigerated (4 ± 1°C) storage and may be commercially exploited as a natural preservative in muscle foods.

Abstract

Purpose

The aim of the article was to focus on various peptides identified in the egg and their probable application as novel ingredients in the development of functional food products. Bioactive peptides of egg origin have attracted increasing interest as one of the prominent candidates for development of various health-promoting functional and designer foods.

Design/methodology/approach

Traditionally known as a source of highly valuable proteins in human nutrition, eggs are nowadays also considered as an important source of many bioactive peptides which may find wide application in medicine and food production. These specific protein fragments from egg proteins which, above and beyond their nutritional capabilities, have a positive impact on the body’s function or condition by affecting the digestive, endocrine, cardiovascular, immune and nervous systems, and may ultimately influence health.

Findings

Several peptides that are released in vitro or in vivo from egg proteins have been attributed to different health effects, including antihypertensive effects, antimicrobial properties, antioxidant activities, anticancer activity, immunomodulating activity, antiadhesive properties and enhancement of nutrient absorption and/or bioavailability. Extensive research has been undertaken to identify and characterize these biologically active peptides of egg origin which has changed the image of egg as a new source of biologically active ingredients for the development of functional foods with specific benefits for human health and treatment and prevention of diseases.

Originality/value

The paper mainly describes the above-stated properties of bioactive peptides derived from egg proteins.

Abstract

Purpose

The purpose of this study is to evaluate the possibility of utilization of pomegranate seed powder and tomato powder in the development of fiber-enriched chicken nuggets.

Design/methodology/approach

The study was designed to incorporate and evaluate the effect of pomegranate seed powder and tomato powder on the quality characteristics of the chicken nuggets. The products were developed by incorporating different levels of pomegranate seed powder (1, 2, 3 per cent) and tomato powder (1, 2, 3 per cent) separately and were analyzed for various physicochemical and sensory parameters.

Findings

The pomegranate seed powder and tomato powder significantly (p < 0.05) increased the fiber content of the chicken nuggets besides improving various sensory attributes of the products. A significant (p < 0.05) effect of the pomegranate seed powder was observed on the pH, emulsion stability, cooking yield and proximate parameters of the chicken nuggets. Tomato powder also showed a significant (p < 0.05) effect on the emulsion stability, moisture and fat content of the products. No significant (p > 0.05) effect of tomato was observed on the pH and cooking yield of the products.

Originality/value

Fiber-enriched chicken nuggets could be developed by incorporating pomegranate seed powder and tomato powder in the formulation besides improving various sensory attributes of the products.

Abstract

Purpose

The purpose of this paper is to examine the influences of consumer perceptions of labelled information and sensory attributes on consumers’ intention to buy fresh milk.

Design/methodology/approach

An experiment was conducted on 117 consumers in a lab at a university. After closely inspecting the labels’ information and tasting two types of milk, participants were asked to fill in a questionnaire, using the direct interview method. Exploratory factor analysis, confirmatory factor analysis and structural equation modelling were applied to analyse the data.

Findings

The results show that products’ labelled information and the sensory perceptions increase the buying intention of both ultra-high temperature treated fresh milk (UFM) and pasteurised fresh milk (PFM). The sensory perceptions of PFM can mediate the relationship between products’ labels and consumer buying intentions, but this relationship is not true for UFM. According to our results, nutritional facts and taking responsibility for one’s health are the keys to fresh milk commercialisation in terms of higher relative weights and commonness.

Originality/value

Although the sensory aspects of milk have been rigorously evaluated in the food science literature, to the best of the authors’ knowledge, few studies have focussed on the sensory perceptions of fresh milk incorporating process categories (UFM and PFM) and their mediating effect between labelled information and buying intention in the social sciences. The study is pioneering in that it investigates the perceptions of sensory attributes affecting consumer purchasing decisions for fresh milk in an emerging market.

Abstract

Purpose

The purpose of this paper is to investigate consumers' reactions to a new kind of green food product that is the so-called lab-grown meat (LGM). This kind of meat does not derive from animal or vegetal cultures but is produced on the basis of “tissue-engineering” technologies, by injecting muscle tissue from an animal into a cell culture, allowing cells to “grow” outside the animal's body. By considering the similar nutritional characteristics of traditional types of meat, and the potential in terms of sustainability, the authors investigate the effect of the advertising, communication focus promoting LGM-based meat, on consumers' willingness to buy (WTB) and word-of-mouth (WOM), by shedding light on the moderator role of consumers' environmentalism and status consumption orientation tendency in influencing such relationship.

Design/methodology/approach

Through an exploratory research design, the authors conducted a study based on a two-cell experiment that manipulated the advertising communication focus by using a hamburger made of synthetic meat related to a fictitious brand called “Gnam”, to manipulate the advertising communication focus (sustainability vs. taste), then evaluating consumers' WTB, WOM, environmentalism and status consumption orientation.

Findings

Results show that the communication focus (sustainability vs. taste) exerts a positive effect on consumers' WTB and WOM, and how such effect is magnified both by consumers' environmentalism and status consumption orientation, in the attempt to show other a green status and their green consumption tendency.

Research limitations/implications

Despite the promising results, the study does not consider other consumers' individual differences, i.e. as for the role of age, or cultural differences.

Practical implications

Practically, this study suggests marketers and managers how to design effective marketing campaigns to incentivise LGM-based food products purchase, and promote positive WOM, on the basis of certain consumers' individual differences useful to segment their clientele in terms of environmentalism, and status consumption orientation tendency.

Social implications

Socially, this study may contribute to incentivising the use of alternative forms of meat as a food product not deriving from animal or vegetal culture, coherently with recent sustainability worldwide claimed goals.

Originality/value

This is the first paper to investigate consumers' reactions to LGM-based food products, by shedding light on the fundamental role of consumers' individual differences.

Abstract

Purpose

This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist.

Design/methodology/approach

This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos.

Findings

Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible.

Originality/value

Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue.

Abstract

Purpose

This paper aims to highlight the candidature of papaya/Carica papaya L. extracts (PLE) and oregano/Origanum vulgare leaves extract (OLE) as novel natural antioxidants, which was further fortified into goat meat nuggets to evaluate quality changes and storage stability at refrigeration temperature (4 ± 1ºC) for 20 days.

Design/methodology/approach

Three different products, namely, control (without phyto-extracts), T−1: PLE (0.5 per cent) and T-2: OLE (1.0 per cent) fortified goat meat nuggets, were prepared and subjected for various quality attributes with relation to storage stability.

Findings

It was observed that pH significantly (p = 0.14) decreased till 10th day of storage i.e. from 6.49 to 6.32 (control), 6.37 to 6.28 (T−1) and 6.45 to 6.43 (T-2) afterword showed increasing trend till further storage of 20 days in control, as well as treated products. Water activity was non-significant (p = 0.01) on first day of storage and decreased up to 20th day. PLE treated product showed good margin of microbiological protection followed by OLE and least was found in control. L* value showed increasing trend (p = 0.03) throughout storage and ranged from 50.15 to 54.27, while a* values were decreased significantly from 10.36 to 9.06, 10.86 to 9.49 in PLE (p = 0.02) and OLE (p = 0.03), respectively. Sensory panel awarded the highest score for fortified goat meat nuggets, justifying the best quality attributes in term of texture attributes of the treated products. Thus, papaya and oregano leave extracts proved in the extension of shelf life and can be further harvested to develop functional goat meat nuggets.

Research limitations/implications

In search of novel bioactive phyto-extract, meat industry focussed most of the research towards natural anti-oxidants. In the view of same, the present research strategy was planned to examine candidature of Carica papaya L. and OLEs as novel natural antioxidant into meat system during aerobic packaging storage. Goat meat nuggets are amongst the most convenient and famous snack, as well as nutritious meat products, but lacks functional properties. Therefore, with implication of present research at practical level, meat industry can develop function goat meat nuggets by incorporating Carica papaya L. and Origanum vulgare extracts as natural and novel bioactive antioxidants with improved functionality.

Originality/value

This is the first attempt to develop functional goat meat nuggets incorporated with papaya/Carica papaya L. and oregano/OLE. This research can lead to be a pioneer work in meat science.

Abstract

Purpose

The purpose of this article is (1) to carry out an ambivalent analysis of the determinants (benefits/risks) of the adoption of cultured meat, (2) to identify their impacts on consumers’ attitudes (cognitive, affective and conative) and (3) to propose a research agenda.

Design/methodology/approach

A systematic review of the relevant literature was conducted. The authors selected 86 articles that were coded using NVivo 12 software according to the theoretical framework chosen for this study: (1) consumer attitude ambivalence (benefit–risk) – conflicting presence of positive and negative attitudes in decision-making, (2) the consumer preference theory – choice of consumers based on utility maximisation or best characteristics/determinants and (3) the three-dimensional perspective of attitude – cognitive, affective and behavioural components. The authors followed the methodological steps (formulation of the research question, identification of relevant scientific studies, evaluation of the quality of studies, summary of evidence and interpretation of results) recommended by Lipsey and Wilson (2001) and Tranfield et al. (2003). Several keywords were drawn from a study by Bryant and Barnett (2019) on cultured meat (CM) nomenclature and its impact on consumer acceptance.

Findings

The identified articles were relatively recent (84/86 articles were published after 2010) and in the fields of agriculture and ethical agriculture (22/86), policy and regulations (12/86) and psychology (11/86). Content analysis helped identify four types of ambivalent determinants for the adoption of cultured meat: ethics, intrinsic, informational and belief. The results suggest the existence of a group of “dominant” determinants for each attitude component. Thus, the dominant determinants of cognitive, affective and conative components are informational, ethical and intrinsic determinants, respectively.

Research limitations/implications

This research is based on a systematic review of literature and is a review of the narrative literature that provides an overview of what is known about cultured meat adoption. The main weakness of this type of method is the feasibility generally associated with the existence (and a sufficient number) of studies that can be included. Other types of the meta-analytic method could have been used and could have explored different measures and biases (e.g. effect sizes, statistical power, sampling error, measurement error and publication bias). Also, as a food technology whose social acceptability would be influenced by all stakeholders, it would be relevant to expand the analysis to other types of stakeholders.

Practical implications

Little is still known to the public about the adoption mechanisms of this technology. In terms of behaviour, Siegrist et al. (2018) suggest that new studies should focus on factors that influence the individual differences in the willingness of consumers to eat or purchase cultured meat. By identifying the dominant target influence of informational determinants on cognitive components, that of ethical determinants on affective components and finally that of intrinsic determinants on conative attitudes, this article offers a first avenue of solution to businesses operating in this new industry, as well as to public authorities, to improve the acceptance of cultured meat. Private businesses will benefit from the results of this research by understanding the underlying motivations of consumers to adopt this type of innovation in order to adjust future marketing.

Social implications

This article, through better understanding of the psychological mechanisms that contribute to its social acceptability amongst the population, has the potential to improve educational campaigns for this technology. The results could thus guide both public policies as well as the regulation of activities related to cultured meat in the coming years, professional orders, private businesses and the general public. It thus provides initial insight needed to understand this public debate.

Originality/value

Research addressing cultured meat has come primarily from agribusiness and environmental and biological sciences. The authors highlighted the need for interdisciplinary collaboration between biological and social sciences to address ethical issues. This article, via multidisciplinary systematic reviews, links environmental/biological sciences and social sciences, and management.
