Abstract

Purpose

The purpose of this paper is to systematically review the functionalities, safety regulations and product applications of herb Stevia rebaudiana extract. This plant material is embedded with multiple functionalities such as antioxidant, antidiabetics, anti-inflammation and antimicrobial. The regulations released from global authorities are covered to ensure the safety premise of stevia. Besides, the product applications of the extract of aerial parts of the herb S. rebaudiana helps us to recognize its value from commercial side.

Design/methodology/approach

Relevant literatures are selected and obtained from main scientific databases such as Google Scholar, Web of Science, PubMed and trade magazines published between 2000 and 2023. The keywords and their possible combinations such as sweetening, antioxidant, antidiabetics, anti-inflammation, safety and product development were used to ensure the preciseness and completeness of literature searching. Major data such as sweetness, total phenolic content and dose together with latter critical conclusions from searched publications were appropriately used and discussed. In this review, approximately 150 scientific literatures were meticulously ordered and analyzed. In applications, it is the first time that sentiment analysis was used to obtain a market assessment of the stevia-containing products.

Findings

This review paper helps rearrange the scientific affairs of those stevia extract’s functions like sweetening, antioxidant, antidiabetics and inflammation. Sweetness indexes of steviol glycosides were summarized together for comparison while various in vitro and in vivo approaches were reviewed to quantify those functions’ capacities and to depict the related mechanism. The regulation of steviol glycoside compounds such as rebaudioside A was established by global authorities such as US Food and Drug Administration and Joint FAO/World Health Organization Expert Committee to ensure the safety endorsement before commercialization. Then, this study discussed about the market performance of stevia ingredients or products with the self-developed data analytics. This study also investigated the product development progress of stevia-containing food products in the categories of beverage, bakery, dairy and confectionery. Those stevia-containing food consumer goods can be acceptable by certain consumers.

Originality/value

This review paper precisely presents the evidential information about the stevia’s multiple functionalities with mechanisms and global regulation milestones. To the best of the authors’ knowledge, it is then the first time to probe the stevia-containing products’ market performance through data analytics.

Abstract

Purpose

Prevention of chronic diseases by means of dietary modification can be achieved by consuming healthier foods with lower sugar content. However, reducing sugar content causes significant impact on the sensory quality and consumers’ acceptance towards local healthy products. This study aims to evaluate the effects of cross-modal interactions of Aroma-Taste-Texture (ATT) in yoghurt drink.

Design/methodology/approach

Fifteen sugar reduced yoghurt drinks [S, sugar percentage (0%, 2%, 4%); T, stevia dosage (0%, 0.01%, 0.02%); P, pectin dosage (0%, 0.3%, 0.6%)] based on ATT were evaluated by 300 consumer panellists on aroma, taste, texture and overall acceptability on a nine-point hedonic scale while sweetness intensity was measured using a seven-point just-about-right (JAR) scale. Interactions between ATT were determined.

Findings

Significant interaction was found between sugar and stevia, with F14 (4S0.02T0P) rated as sweeter than F4 (0S0.02T0P) (p = 0.003) and higher overall liking score than F11 (4S0T0P) (p = 0.001). Similarly, significant interaction was found between sugar and pectin, with F2 (0S0T0.6P) rated as significantly lower overall liking score and less sweet than F1 (0S0T0P) (p = 0.0001). Likewise, significant interaction was found between stevia and pectin, with F2 (0S0T0.6P) rated as significantly lower overall liking score and less sweet than F1 (0S0T0P) (p = 0.0001). Overall, F5 (0S0.02T0.6P) scored highest in overall liking and closest to the ideal sweetness (JAR = 4) indicating the possibility to apply 100% sugar replacement.

Originality/value

Application from the present study could be great potential solution in developing healthier range products while meeting consumer preference. The present study concluded that interactions of ATT of yoghurt drink will induce desirable changes in sensory and sweetness perception.

Abstract

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.

Abstract

Purpose

The purpose of this study is to test the visual superiority effect in a verisimilar scenario that an industry association seeks to manipulate consumers using a visual element in its ad while providing an ostensibly balanced claim about the potential health effects of stevia.

Design/methodology/approach

Two experiments were conducted. In Study 1, an online experiment was conducted with a sample of 112 adult consumers using a two-group (headline frame type: gain vs loss), post-test only design with additional planned analysis of an individual difference (i.e. regulatory focus). In Study 2, another online experiment was implemented with a sample of 175 adults using a 2 (headline frame type: gain vs loss) × 2 (image valence: positive vs negative) between-subjects design with additional planned analysis of regulatory focus. The hypotheses were tested by running the PROCESS macro on SPSS.

Findings

The results showed that when exposed to the advertising message designed to elicit uncertainty, participants relied more on the visual than the textual content (i.e. framed headline and body text) in forming attitude toward the behavior (i.e. consuming stevia). Analysis of cognitive responses also revealed that those who received the stimulus ad with an image added (Study 2) generated significantly fewer thoughts related to the textual content of the ad than those who received the ad with no image (Study 1).

Originality/value

This study represents one of the earliest experimental inquiries into the visual superiority effect in an advertising context. While earlier studies have tended to rely on dual-processing models to test the effects of advertising stimuli featuring both textual and visual elements, the findings of this study (e.g. visual content overwhelmed its textual counterpart in producing persuasive effects) somewhat contradict the premise of dual-processing models.

Abstract

Purpose

This study aims to illuminate the field conditions under which social entrepreneurship can become institutionalized and transform the existing institutional fields.

Design/methodology/approach

A comparative case study was conducted among three social enterprises, within different regional institutional fields, following a most different systems design: OTELO, in Mühlviertel, ADC MOURA, in Baixo Alentejo and STEVIA HELLAS in Phthiotis.

Findings

The results indicate some of the field conditions under which an institutionalization of social entrepreneurship can thrive, namely, a high civil approval, a highly institutionalized and decentralized institutional field that allows the social enterprise to remain autonomous, as well the anchoring of the venture to a pre-existing counter-hegemonic narrative or/and to an embedded network that drives the dissemination a new institutional logic forward.

Research limitations/implications

The institutionalization of the voluntary collective action that social entrepreneurship embodies has significant limitations. The same is true for innovation, which tends to lose its innovative spirit as it becomes institutionalized. Future research has to explore if institutionalized social entrepreneurship can maintain a voluntary perspective and an innovative drift.

Originality/value

Most studies on institutional entrepreneurship deploy in-depth case studies while multi-case comparative research remains rare. The current comparative study adds significantly to the understanding of institutional entrepreneurship, as it compares different degrees of institutionalization and successful institutional entrepreneurs to non-successful ones.

Abstract

Purpose

The purpose of this study is to collect and assess the evidence available on the effect of non nutritive sweeteners on appetite, weight and glycemic regulation. As a replacement for sugars, non-nutritive sweeteners (NNSs) are widely being used in different food products with the assumption that these would lower calorie intake and help to manage weight and blood sugar levels better. However, studies using animal models have reported that chronic exposure to NNSs leads to increased food consumption, weight gain and insulin resistance.

Design/methodology/approach

Evidence was acquired from systematic reviews or meta-analyses (2016–2021) of relevant clinical studies, especially randomized control trials using Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.

Findings

The review showed NNSs exposure did not conclusively induce increased food intake or change in subjective appetite ratings. Appetite biomarkers like ghrelin, gastric inhibitory peptide, C-peptide levels and Peptide YY remained mostly unaffected by NNSs. Meta-analyses of human randomized control studies showed a reduced energy intake and body weight. No significant change was seen in blood glucose levels, post-prandial glycemic or insulin response after consumption of NNSs. Adequate evidence is not available to conclusively say that NNSs influence gut health at doses relevant to human use.

Research limitations/implications

Most studies which are prospective cohort, observational and cross-sectional studies suggest that use of NNSs may promote obesity and metabolic syndrome in adults. Such studies are plagued by confounding variables and reverse causation. Mechanistic evidence is mostly based on in-vitro and in-vivo studies. The same causal pathways may not be operative or relevant in humans.

Practical implications

This review of available literature concludes that to achieve specific public health and clinical goals, the safe use of NNSs for the reduction of intakes of free sugars and energy should be explored. This would be possible by educating the consumer about energy compensation and understanding the nutritional content of artificially sweetened products in terms of calories coming from fat and complex carbohydrates used in the product.

Originality/value

This study was, thus, designed with the objective of examining the usefulness of NNSs in human population, especially with respect to insulin regulation, glycemic control and weight management. Well-designed randomized control trials which control for confounding variables are needed to generate high quality evidence.

Abstract

Purpose

There is growing awareness internationally of the need to reduce intake of added sugars. The purpose of this study was to examine consumer sugar knowledge and food label use.

Design/methodology/approach

This cross-sectional online survey included 229 adult participants (85% female and 15% male). Participants completed measures of demographics, sugar knowledge, interest in food and nutrition, food choice motivations and beliefs and food label use. The sample of convenience showed that participants were from Australasia (n = 90), the USA (n = 90) and other Western (Europe and Canada, n = 49) countries.

Findings

Overall, participant sugar knowledge predicted nutrition label use over and above individual demographic and psychological characteristics (interest in food and nutrition, health beliefs and food choice motivations) (p < 0.001). Country comparisons revealed that those in Australasia reported lower sugar knowledge compared to the USA (p =< 0.001) and other Western countries (p = 0.028).

Research limitations/implications

Overall, participant sugar knowledge predicted nutrition label use over and above individual demographic and psychological characteristics (interest in food and nutrition, health beliefs and food choice motivations) (p < 001). Country comparisons revealed that those in Australasia reported lower sugar knowledge compared to the USA (p =< 0.001) and other Western countries (p = 0.028).

Originality/value

This study explored sugar knowledge as a unique predictor of food label use, taking into account individual characteristics in demographics, food choice motivations and health beliefs.

This paper aims to study how diabetics/pre-diabetics (D) and non-diabetic (regular consumers of sweeteners (C) or not (NC)) perceive and consume sweetened processed food in Brazil.

Abstract

Purpose

This paper aims to study how diabetics/pre-diabetics (D) and non-diabetic (regular consumers of sweeteners (C) or not (NC)) perceive and consume sweetened processed food in Brazil.

Design/methodology/approach

A cross-sectional study (n = 2,204) was carried out to gather information about: consumption of 14 sweetened food/beverage categories, perception of sugar/sweeteners (check-all-that-apply (CATA) test), understanding of sugar claims and socioeconomic/demographic/consume profile. Chi-square test/Fisher exact tests were used to analyze the contingency tables. CATA test results were evaluated using Cochran Q test, RV coefficient and Kruskal-Wallis test.

Findings

Results revealed that although diabetics/pre-diabetics consumed less sugary products than non-diabetics (p < 0.001), >50.0% of them preferred sugary candies, bakeries, ready-to-drink fruit juice, ice cream, chocolate and ready-to-eat desserts. D, NC and C similarly perceived (RV = 0.99) sugar (sensory desirable, but penalized due to its health impact), naturally extracted sweeteners (opposite description of sugar) and chemically synthesized sweeteners (penalized by sensory and health impacts). Regarding the claims, those that mean the absence of sugar were correctly understood for = 90.0% participants, while incorrect interpretations were observed for “containing sugars from own ingredients” (42.7%) and “light on sugar” (21.0%), without differences between consumer groups (p = 0.93).

Research limitations/implications

This study was carried out with a convenience sample.

Practical implications

Results can be applied to support food policies and educational campaigns (improving consumer information on processed sweetened foods) and to guide product development in the food industry.

Originality/value

This is the first study to evaluate the Brazilians’ behavior regarding the perception of sugar and sweeteners, the choice of different sweetened processed food, and understanding of sugar claims.
