Abstract
With increasing global demand for seafood, seafood byproducts (SB) utilization can contribute to a more sustainable food supply chain through waste-to-value food product development. However, consumer perceptions of SB (e.g., fish skin and bones) are underexplored. Therefore, this study aims to evaluate some factors influencing consumers' willingness-to-try seafood byproducts. An online survey was conducted in the USA regarding intervention of SB informational cues with N = 904 adult seafood consumers internationally. The proportion of consumers willing to try SB increased significantly (McNemar's test, α = 0.05) from 47% to 68% after SB safety and health claims had been presented in the questionnaire. Gender, race, SB knowledge, and previous SB consumption were significant predictors of trial intent (based on logistic regression), as were emotional baseline scores during the COVID-19 pandemic. Males were more open to SB consumption than females, and racial identity was associated with differential responsiveness to SB information. Higher levels of "bored" and "unsafe" feelings, and lower levels of "free" were associated with increased SB trial intent. Potential SB consumers identified fish products (82% willingness-to-try); seasoning mix, sauces, and dressing (71% willingness-to-try); and soup and gravy products (62% willingness-to-try) as most appropriate for SB incorporation. Predominant reasons for SB avoidance were concerns about sensory quality, safety, and nutrition. These consumer-driven data could guide SB product development concepts to encourage trial and overcome aversions through new consumption experience.

Abstract
This narrative historical review examines the wide range of approaches that has been trialled/suggested in order to reduce the consumption of salt. While sodium is an essential micronutrient, there is widespread evidence that high levels of consumption are leading to various negative health outcomes. This review summarises the evidence relating to the various approaches that have been put forward to date to help reduce salt consumption over the years, while also highlighting a number of important questions that remains for future research. Solutions to reducing salt consumption include everything from the gradual reduction in salt in foods through to the reduction in the number/size of holes in saltshakers (what one might consider a behavioural nudge). Physico-chemical solutions have included salt replacers, such as monosodium glutamate (MSG) through to the asymmetric distribution of salt in processed (e.g., layered) foods. A wide range of sensory approaches to modulating expected and perceived saltiness have also been suggested, including the use of salty aromas, as well as suggesting the use of colour cues, sonic seasoning, and even textural primes. It is currently unclear whether different salty aromas can be combined to increase odour-induced taste enhancement (OITE) effectiveness. In the years ahead, it will be interesting to assess how long such solutions remain effective, as well as whether different solutions can be combined to help reduce salt consumption without having to compromise on taste/flavour

Abstract
Consumers all across the world are looking for the most delectable and appealing foods, while also demanding products that are safer, more nutritious, and healthier. Substitution of synthetic colorants with natural colorants has piqued consumer and market interest in recent years. Due to increasing demand, extensive research has been conducted to find natural and safe food additives, such as natural pigments, that may have health benefits. Natural colorants are made up of a variety of pigments, many of which have significant biological potential. Because of the promising health advantages, natural colorants are gaining immense interest in the dairy industry. This review goes over the use of various natural colorants in dairy products which can provide desirable color as well as positive health impacts. The purpose of this review is to provide an in-depth look into the field of food (natural or synthetic) colorants applied in dairy products as well as their potential health benefits, safety, general trends, and future prospects in food science and technology. In this paper, we listed a plethora of applications of natural colorants in various milk-based products.

Abstract
In response to health concerns generated by increased sodium intake, many new approaches have been studied to reduce the sodium content in processed food. It has been suggested that reducing sodium in the food supply may be the most appropriate solution. The aim of this scoping review was to establish what sodium reduction strategies are effective in maintaining acceptable sensory qualities for various food industry applications. Studies that evaluate and report on the effectiveness of a sodium reduction strategy relevant to food and included outcomes detailing how the strategies were received by human subjects using sensory data are included, as well as book chapters, literature reviews, and patents focusing on sodium reduction strategies. Only those published in English and since 1970 were included. Literature was obtained through Scopus, PubMed, EBSCOhost, and ScienceDirect databases, whereas patents were obtained through US Patent Trademark Office, Google Patents, and PATENTSCOPE databases. Two-hundred and seventy-seven primary studies, 27 literature reviews, 10 book chapters, and 143 patents were selected for inclusion. Data extracted included details such as analytical methods, broad and specific treatment categories, significant outcomes, and limitations among other material. Sodium reduction methods were categorized as either salt removal, salt replacement, flavor modification, functional modification, or physical modification. Although salt removal and salt replacement were the majority of included studies, future research would benefit from combining methods from other categories while investigating the impact on sensory characteristics, technological aspects, and consumer perception of the strategy.

Abstract
Sodium reduction influences the quality of processed meat products that, in turn, affect consumer acceptance. The objective of this study was to develop and evaluate the texture, color, and sensory acceptability of reduced-sodium Vienna sausage. A three-component mixture design (0-65% NaCl; 35-100% KCl; 0-20% glycine [Gly]) was performed to obtain an optimal salt mixture based on 14 sausage formulations. Mixture response surface plots revealed the optimal reduced-sodium Vienna sausage containing 20.13-65.00% NaCl, 35.00-60.15% KCl, and 0.00-20.00% Gly (this salt mixture constituted 1.35% of the formulation). One optimal laboratory-scale sausage, formulated with 21.43% NaCl, 59.71% KCl, and 18.86% Gly, was further selected for commercial scale-up production (a 25-kg batch). Both laboratory-scale and scale-up products were comparably acceptable (5.9-6.6 vs. 5.9-6.7) for overall liking, flavor, saltiness, and texture, and contained 315.4-333.5 mg sodium/100 g, hence having >25% sodium reduction compared to the control (569.5 mg/100 g) according to US Food and Drugs Administration regulation. This study demonstrated the feasibility of a scale-up production of acceptable reduced-sodium Vienna sausage formulated with a salt mixture of NaCl/KCl/Gly. PRACTICAL APPLICATION: Processed meat products are one of the major sources of daily dietary sodium in the form of sodium chloride. Recently, there is an increased demand by consumers for healthier meat products. Of particular interest is finding solutions for sodium reduction in meat products while maintaining sensory properties and consumer acceptance. This study demonstrated that a mixture of KCl and Gly could be used as partial NaCl substitution in the commercial scale-up of Vienna sausages without drastically compromising sensory acceptability.

Abstract
With increasing demand for ready-to-eat (RTE) fresh vegetables, it is important to understand how visual information cues, both intrinsic and extrinsic, affect consumer perception of these products. This study developed an emotional and wellness lexicon related to RTE salads. Subsequent questionnaires with images of salads were used to quantify consumer (N = 150) emotional and hedonic perceptions related to green color shade, shape/size of pieces, multicolor scheme, product name, and packaging. The different visual cues significantly impacted emotions and their intensities. Qualitatively, feelings of health and wellness predominated across salad samples. Negative emotions were more influenced by size of piece and green-color (intrinsic), while positive emotions were influenced by viewing salads of multiple colors (intrinsic) and packaging (extrinsic). Pale green salads were generally less liked than darker green ones. Values, in one case, ranged from 4.39 to 7.28 (on a 9-point hedonic scale), but naming the product (“iceberg lettuce”) did raise the lowest score to 5.75. The addition of vegetables with orange and purple colors to the salad mix had a positive impact on the perception of pale green salads. This study demonstrated that intrinsic and extrinsic visual cues significantly influenced consumer emotions, hedonic perception and purchase intent of RTE salads, but the effects of extrinsic cues were generally less prominent.

Abstract
Colored Cheddar cheeses are prepared by adding an aqueous annatto extract (norbixin) to cheese milk; however, a considerable proportion (∼20%) of such colorant is transferred to whey, which can limit the end use applications of whey products. Different geographical regions have adopted various strategies for handling whey derived from colored cheeses production. For example, in the United States, whey products are treated with oxidizing agents such as hydrogen peroxide and benzoyl peroxide to obtain white and colorless spray-dried products; however, chemical bleaching of whey is prohibited in Europe and China. Fundamental studies have focused on understanding the interactions between colorants molecules and various components of cheese. In addition, the selective delivery of colorants to the cheese curd through approaches such as encapsulated norbixin and microcapsules of bixin or use of alternative colorants, including fat-soluble/emulsified versions of annatto or beta-carotene, has been studied. This review provides a critical analysis of pertinent scientific and patent literature pertaining to colorant delivery in cheese and various types of colorant products on the market for cheese manufacture, and also considers interactions between colorant molecules and cheese components; various strategies for elimination of color transfer to whey during cheese manufacture are also discussed.

Abstract
Emojis can be used to explore food-evoked emotions in order to provide information that can support the product development and marketing decisions. This study aimed to evaluate consumers' acceptance, purchase intent and emotional responses to milk beverages, with and without kefir added, before and after these consumers were informed about the products' composition (0%, 15%, 30% and 50% m/v) and health claims toward kefir (blind and informed tests, respectively). Emotional responses were assessed by emoji use within a RATA questionnaire in order quantify the perceived significance of the emojis chosen. In the informed test, the consumers' perception of the sensory attributes of the milk beverages, such as their perception of an acid taste in added kefir beverages was shown to have changed. Overall, participants attributed significantly higher acceptance and purchase intent scores to added kefir beverages after they had been informed on its health benefits. In addition, expressions of positive emotion increased when participants were exposed to stimuli related to health benefits of kefir (15%, 30% and 50% m/v), while negative expressions of emotion decreased. The provided information of kefir modified valence and arousal in subjects, and it can be said that to 30% of kefir can be added to yogurt without compromising its sensory acceptability. Thus, health benefits alone cannot improve product acceptance, since participants found a 50% addition of kefir to be unpleasant when tasted during a blind test. Mixed beverages may present a probiotic beverage alternative for consumers who dislike kefir milk, but want to include it in their diets. The implications of liking and purchase intent and how they are linked to emotions are discussed in this paper as well.

Abstract
Visual cues have been reported to influence taste and flavor perceptions. The objectives of this study were to evaluate the impact of visual cues (color and viscosity) of syrups on expected sweetness and bitterness perception (Study I), and on sweetness perception and sweetness liking of brewed coffee after syrup had been added, and the amount of syrups to be added to brewed coffee (Study II). For Study I, the visual stimuli were developed by varying viscosity (80, 800, and 8000 cP) and yellow index (YI) (0.04, 0.08, 0.16, and 0.32), resulting in 12 syrups with 20 degrees Brix. Visual observations indicated greater expected sweetness perceptions of syrups when YI and viscosity were increased. However, YI, but not viscosity, affected expected bitterness perceptions. Increasing YI raised the frequency (%) of "too sweet" perceptions of syrups on a JAR scale. For Study II, only four syrups (LC1, LC2, HC1, HC2; L = viscosity, 80 cP, H = 8,000 cP; C1 = YI 0.04, C2 = YI 0.32) were studied. The visual perception affected consumers' behaviors concerning the amount of syrup added to brewed coffee. Consumers added the greatest volume of syrups with the lowest viscosity and YI (LC1), while the lowest volume of syrups with the highest viscosity and YI (HC2). There were no significant differences in sweetness liking of brewed coffees added with LC1, LC2, and/or HC1 syrups. This study indicated that visual cues could potentially intensify the perceived sweetness of syrups, and reduced the volume of syrup added to brewed coffee and consequently calories consumed. PRACTICAL APPLICATION: Sensory visual cues associated with a syrup can be used to reduce the volume consumed and thereby promote reduced consumption of calories while maintaining sensory acceptability. Increasing a syrup's viscosity and yellow/brown color intensity enhanced the expectation of sweetness and resulted in less volume of syrup added to brewed coffee. This research demonstrated that the impact of visual cues not only influenced expectation and sensory acceptability but also impacted the cognitive process of eating. This strategy could provide a way to promote a sustainable reduction in sugar and, hence, calorie consumption without compromising sensory liking.

Abstract
BACKGROUND In duplicated ranking tests, panelists either rank duplicates separately (2SS) or jointly in a single session (1SS). This study compared data analyses of duplicated yellow color intensity rank data using Friedman versus Mack-Skillings (M-S) tests. Panelists (n = 75) ranked an orange juice set twice - a similar-samples set (100%, 95% versus 90%); samples other than the 100% juice were prepared by dilution with water. Rank sum data were obtained from (a) intermediate ranks from jointly re-ranked scores of 2SS for each panelist, and (b) joint rank data of all panelists from the two replications in 1SS. Both (a) and (b) were analyzed using the M-S test. The median rank data (c) for each panelist from two replications were analyzed using the Friedman test. RESULTS Comparing M-S with the Friedman tests, the former generally produced higher test statistics and lower P-values than the latter. However, when considering the pattern of post hoc pairwise significant differences, both tests yielded similar conclusions. CONCLUSION This study demonstrated that, in a duplicated ranking test with three samples that were very similar in color, separating the two replications into two complete individual ranking tests or serving sessions (2SS) may prevent sensitivity loss due to fatigue that is otherwise experienced when evaluating all samples together in a single session (1SS). We expected to find the M-S test to be more sensitive than the Friedman test; however, this hypothesis was not supported by the post hoc (Tukey's honest significant difference (HSD)) multiple comparison test results under the specific test conditions in this study. © 2019 Society of Chemical Industry.

J Food Sci 2019; 84:3018-3026. [PMID: 31546288 DOI: 10.1111/1750-3841.14808] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Revised: 07/13/2019] [Accepted: 08/20/2019] [Indexed: 11/29/2022]
Abstract
The effects of visual cues on familiarity, expected heat intensity, liking of appearance, emotional and wellness responses, and purchase intent (PI) before and after disclosing information associated with red chili powders were determined using a 3-point scale, a 15-cm line scale, a 9-point hedonic scale, a 15-cm line scale, and a binomial scale, respectively. In this study, consumers only visually evaluated red chili powder samples without sniffing nor tasting. Eight chili powders were prepared according to a 23 factorial design: roasted (Ro) compared with unroasted (Un); whole pod with seeds (Wh) compared with seedless (Sl); coarsely (Cr) compared with finely ground (Gr). Thai consumers (N = 230) were generally more familiar with samples having coarse particles and more reddish color (lower hue angle and higher a* values) than samples having finely ground particles and less reddish/more yellowish color (higher hue angle and lower a* values). The expected heat intensity and liking scores for appearance were lower for samples with higher hue values, particularly RoWhGr and RoSIGr samples. All scores for emotion/wellness terms, except curious, were generally higher for samples with lower hue angle and higher a* values (redness). The consumer familiarity to the appearance of the samples influenced expected heat intensity, liking of appearance, and emotion/wellness responses. PI increased by >10% after presenting "organic," "aflatoxin free," and "organic and aflatoxin free" product statements to consumers. Results showed that familiarity, overall liking of appearance, color liking, fine particles liking, and healthy as well as wild terms were significant predictors for PI (odds ratio = 1.282, 1.519, 1.314, 1.158, 1.056, and 0.939, respectively) of red chili powders. PRACTICAL APPLICATION: This study showed that consumer familiarity to the appearance (visual cues) of red chili powder affected expected heat intensity, liking of appearance, and emotion/wellness responses, which, in turn, affected purchase intent (PI). Samples with more reddish color and coarse particles were perceived to be more familiar than those with more yellowish color and finer particles. Familiarity, overall liking of appearance, color liking, fine particles liking, and healthy and wild terms were significant predictors for PI of chili power. The results demonstrated the importance of visual cues on the consumers' expectation and PI of red chili powder, thus offering valuable information for manufacturers.

Seafood Flavor Perception, Liking, Emotion, and Purchase Intent of Coated Peanuts as Affected by Coating Color and Hydrolyzed Squid Peptide Powder. J Food Sci 2019; 84:1570-1576. [PMID: 31120576 DOI: 10.1111/1750-3841.14638] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2019] [Revised: 03/28/2019] [Accepted: 04/09/2019] [Indexed: 02/05/2023]
Abstract
This study evaluated effects of green compared with brown coating colors and varying levels of hydrolyzed squid peptide powder (HSP) on seafood flavor perception, sensory liking, emotions, and purchase intent (PI) of coated peanuts. Dried squid head was enzymatically hydrolyzed to produce HSP, which was then incorporated into peanut coating material at 0%, 0.89%, 1.78%, and 2.66% levels. Green-coated peanuts (GCP) and brown-coated peanuts (BCP) were produced and tested with U.S. consumers. A 2-AC test (N = 100 consumers) was used to determine effects of coating colors on expected/perceived seafood flavor intensity of GCP compared with BCP at an equal HSP level based separately on looking, smelling, and tasting. Only tasting produced perceptual differences, at 1.78% and 2.66% HSP, with stronger seafood flavor intensity observed for GCP. Consumer testing (N = 160) yielded low mean seafood aroma liking scores for BCP (4.04) and GCP (4.13) at 2.66% HSP. The emotion "disgusted" was most affected by HSP addition for GCP. Presenting consumers with health benefit information (HBI) increased positive PI from 62.5% to 81.25% for BCP at 1.78% HSP, which had higher mean overall liking scores (6.05 before HBI, 6.24 after HBI) than 2.66% HSP samples. Overall liking was a significant predictor for positive PI with odds ratios of 1.52 to 2.20. Overall, green color and HSP addition levels of the coating inserted negative effects on liking, emotion, and PI of coated peanuts. This study demonstrated that HSP made from byproduct of squid processing could be successfully incorporated into coated peanuts, supporting the concept of sustainability of food supply. PRACTICAL APPLICATION: In this study, the functional peptide ingredient made from squid head, a byproduct from seafood industry, was incorporated into coated peanuts. Effects of different coating colors (green compared with brown) and varying levels of hydrolyzed squid peptide powder on consumers' seafood flavor perception, liking, emotions, and purchase intent of seasoned coated peanuts were clearly observed. The color of the coating material played an important visual cue that influenced product liking. Presenting consumers with health benefit information increased overall liking and positive purchase intent of the samples. Multisensory interactions of color and seafood aroma/flavor in these products should be further optimized.
