Abstract
Purpose
This study aims to develop nutritious and functional gluten-free cakes for celiac patients by substituting rice flour with unripe banana peel flour (UBPF) (0%, 5%, 10%, 15% and 20%) and to propound some chemical, textural and sensorial properties of cakes. A secondary purpose was also to contribute to waste management of the banana products industry by reevaluating the peel.
Design/methodology/approach
One-way analysis of variance and Duncan’s multiple comparison test (p < 0.05) were used to determine differences among the mean values. Proximate analysis, color, texture profile analysis, antioxidant activity, mineral composition and sensorial analysis were carried out. Data was analyzed using SAS software. Cake production was carried out in three replications.
Findings
UBPF in this study had high protein (11.2%) and dietary fiber (18.3%) as well as high antioxidant activity. In all, 5%–20% UBPF-substituted cakes had enhanced dietary fiber (2.5%–3.7% dry matter), ash content (1.6%–1.9% DM) in comparison to control cake (1.4% and 1.4%, respectively). 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of enriched gluten-free cakes increased by 102%–534%, whereas ferric-reducing antioxidant power increased by 29.6%–143%. Up to 10% UBPF substitution resulted in texturally and sensorially acceptable, nutritious gluten-free cakes.
Practical implications
The developed product can be used practically for several applications as a healthy alternative. The use of unripe banana peel represents a promising strategy to increase the nutritional value and number of ready-to-eat food in the gluten-free market.
Social implications
This study propounds a nutritious, functional and sensorially acceptable gluten-free cake for celiac people to use practically while socialization. Cakes which are appreciated by panelists in sensory analysis will create product variety in kitchens, markets and social areas, in particular for those people suffering from celiac and gluten intolerance.
Originality/value
This is the first study to consider UBPF as an ingredient in gluten-free cake formulation. The product may positively contribute to the life quality of celiac people by propounding a gluten-free snack food for consumption in their social life. This study is also an example of the contribution of banana by-products toward the implementation of the circular economy.

Abstract
Purpose of the paper
This paper gives an overview of the prevalence, symptoms, diagnosis and management of coeliac disease and associated disorders. It also gives some background to gluten testing in foods and developments in identification of gluten‐free foods at consumer level.
Design/methodology/approach
The most up‐to‐date literature on various aspects of the disease have been considered and included in the report.
Findings
Coeliac disease is now known to affect one in 100 of the population, including both adults and children. As more is understood about the pathophysiology of the disease and antibody screening techniques improve rates of diagnosis are increasing. The biopsy is still required for a firm diagnosis. The range of symptoms that is now recognised is far wider than previously thought, but symptoms are still often missed, or mis‐diagnosed as IBS. The treatment for coeliac disease is the gluten‐free diet, which controls the symptoms and reduces the risk of complications such as osteoporosis and gut cancer. Prescriptions of gluten‐free foods are known to improve adherence to the diet, and with the range of suitable foods in supermarkets increasing rapidly, gluten‐free living is becoming easier.
Originality/value
Information on several aspects of coeliac disease are presented in this paper to give the non‐expert a general, up‐to‐date overview of the disease.

Abstract
Purpose
The purpose of this paper is to contribute to the understanding of the tourism service experience of consumers with vulnerabilities. Moreover, this research analyses the pre-core service encounter in the tourism services sector, which is one of the most important phases in the service experience. The objective is to understand how vulnerability might influence risk perceptions when people travel. To this end, this study focusses on individuals with coeliac disease (CD) and non-coeliac gluten sensitivity (NCGS) as a specific group to test the hypotheses. For the millions of individuals with CD or NCGS, food is one of the most critical elements of a trip and the reason for vulnerability perception. The research also proposes measures suggested by survey respondents to improve the information search process of vulnerable travellers before a trip.
Design/methodology/approach
A mixed-method was used based on a survey of 813 responses from people diagnosed with CD and NCGS. The individuals were placed in three groups according to their perception of how strongly their disease impacts their trips: low impact, medium impact and high impact.
Findings
The results confirm that people with a high-risk perception due to their vulnerability spend more time searching for information prior to the trip than people without this perception. In this sense, individuals that feel more vulnerable, tend to use more personal information sources and also make greater use of online information sources. The participants affected by CD and NCGS proposed measures to reduce their perceived vulnerability. These proposals are based on information about the disease, specific information from the tourist industry at the destination and various online, as well as offline information channels.
Originality/value
The novelty of this research is mainly found in the study in the study of how consumers with vulnerabilities behave during the information process before travelling. From a holistic approach and based on both, marketing service theory and the risk perception perspectives, this research is focussed on vulnerable individuals affected by CD and NCGS to find answers to the problems they face during the pre-core service encounter.

Abstract
Purpose
The purpose of this paper is to divulge the current knowledge about the nutritional and functional characteristics of Cañihua (Chenopodium pallidicaule Aellen), in addition to its potential applications in the food industry since research studies related to it are still limited compared to other cereals of greater diffusion.
Design/methodology/approach
The scientific information was collected from Web of Science, Scopus and Google Scholar databases, using keywords such as nutrition value of Chenopodium pallidicaule, amaranth and pseudocereals. Consistent information was selected according to its relevance, year of publication and accuracy with the topic. A total of 49 research papers were selected.
Findings
Cañihua is a grain with high nutritional potential, considered a superfood because it has a high protein quality, a balanced composition of essential amino acids and unsaturated fatty acids, with a high concentration of linoleic and oleic acid. Besides, it has a good level of bioactive compounds with high antioxidant capacity. However, its production and consumption are limited outside its area of origin, although its cultivation is possible under harsh conditions.
Originality/value
This paper, through a systematic bibliographic review, highlights the potential of cañihua to be considered in the development of food products with high nutritional and functional value. The information compiled will help researchers and professionals become aware of the importance of this grain and join forces in its processing and enhancement of its attributes.

Abstract
Purpose
According to the dietary needs of celiac people and very limited variety of commercially available foodstuff, the demand for gluten-free products is increasing every day. Keeping this in view, the present study aims to develop healthier gluten-free chicken products by using different cereal sources and to determine the effect of substitution of wheat flour with gluten-free flours on quality of chicken products.
Design/methodology/approach
Buckwheat, chickpea and rice flours were used as gluten-free flours for the production of chicken products. The physical (yield parameters, crust colour), chemical (proximate composition, caloric value, pH) and sensorial properties of coated chicken products were measured. Duncan's multiple range test and principles component analysis were performed.
Findings
Gluten-free flours were significantly effective on yield parameters, colour, moisture, protein, lipid and caloric value of the samples (p < 0.05). The results showed that gluten-free chicken products had better pickup, lighter appearance, higher cooking yield and moisture, lower cooking loss, oil absorption, lipid and caloric values compared to commercial wheat flour coated control. Regarding the overall impression rank sums, the panellists were more preferred gluten-free products than control group. The samples coated with chickpea flour were best rated by the panellists. The results of the study suggested that the use of chickpea coating flour could be best nutritionally and sensorially suitable option for producing gluten-free chicken product.
Originality/value
This study offers potential healthy alternatives to increase the variety of gluten-free products that celiac people desperately need today.

Abstract
Purpose
The prevalence of celiac disease is increasing alarmingly. The only and effective treatment for this disease is a strict gluten-free diet Efforts have been made by industrialists to produce gluten-free products (GFPs); however, their low availability and high cost, compared to gluten-containing products (GCPs) still remain among the factors that cause gluten-free adherence failure. The objective of this survey is to compare the availability and cost of GFPs in supermarkets in two Moroccan cities, Marrakech and Casablanca, and on e-commerce platforms and see how they compare to GCPs.
Design/methodology/approach
This is a cross-sectional study that targets supermarkets and e-commerce websites that sell GFPs food and their GCPs equivalents. The price of each product is recorded per 100 g.
Findings
The study surveys 271 GFPs and their 579 GCPs equivalents that were subsequently divided into six categories. The “GF Cookie and Cakes” category came on top of the list of products. GFPs were more available on e-commerce websites than at supermarkets in two Moroccan cities (p = 0.003). The GFPs are 364% (115–1309%) more expensive than their GCPs counterparts. Also, the authors recorded a significant price difference between GFPs sold in supermarkets and those sold on online.
Originality/value
This study reveals that labeled GFPs are less available and more expensive than their equivalents GCPs in Morocco. This affects GF diet adherence and quality of life of celiac patients. The patients who use GFPs need financial compensation from the national government.

Abstract
Purpose
Celiac disease patients cannot consume gluten-containing diets; thus, gluten-free products should be offered to meet the nutritional needs of these patients. The purpose of this study was to produce gluten-free tarhana for celiac disease patients using corn flour instead of wheat flour and investigate some physicochemical properties of tarhana. Hydrocolloids were used to compensate for technological deficiencies caused by the absence of gluten.
Design/methodology/approach
Hydrocolloids including guar gum, xanthan gum and locust bean gum were added at concentrations of 0.5% and 1.0% to the corn flour. The substituted corn flour samples were used to produce tarhana powder.
Findings
The pH and acidity measurements were carried out in 0th, 24th and 48th h of fermentation, and for all samples, the pH gradually decreased during fermentation, whereas the acidity increased. According to the color measurements (L, a and b values), it was observed that there was no significant difference (p = 0.588) between the gums in terms of L values in tarhana dough samples. Water retention capacity values of control, guar gum 1%, xanthan gum 1% and locust bean gum 1% were found to be 1.1, 1.1, 0.7 and 1.2 mL/g, respectively. The viscosity measurements were carried out at three different temperatures (30°C, 45°C and 60°C), and the viscosity values were found to decrease significantly (p = 0.000) with the increase in temperature for all the samples studied. The highest viscosity values were obtained by 1.0% xanthan gum (4,333 mPa s) and 0.5% locust bean gum (3,575 mPa s) added tarhana samples for 3 rpm at 30°C. Xanthan gum addition showed the lowest foam capacity values (0.04 mL/mL) among the samples. The samples with guar gum, xanthan gum and locust bean gum are recommended with regard to consistency and foam stability in the production of tarhana.
Originality/value
This study confirms that the use of gums in tarhana, a gluten-free system, is beneficial for the technological aspect. The unfavorable properties that can be seen because of the absence of gluten in corn flour tarhana can be compensated with the use of hydrocolloids, and tarhana can be recommended to celiac disease patients.

Abstract
Purpose
Coeliac disease (CD) is a lifelong autoimmune disorder and is managed with a strict gluten-free (GF) diet. At diagnosis, an individual's nutritional status is affected by how long CD has been active, their dietary intake, intestinal inflammation and degree of malabsorption. This study explores if age and time since diagnosis affect nutritional knowledge, eating habits and emotional wellbeing of participants.
Design/methodology/approach
An online survey using Qualtrics was conducted. The survey consists of 4 sections exploring (1) demographics, (2) nutritional knowledge, (3) eating habits and (4) quality of life (QoL). A total of 162 valid questionnaires were completed.
Findings
Those who'd been diagnosed for more than 5 years demonstrated better knowledge about GF or gluten containing products. Social interactions are limited by concerns about becoming ill, unwanted attention and increased financial costs. Eight-eight % of participants would go hungry at social events. Those aged between 40–59 and above 60 years felt more financially restricted compared to younger adults (χ2(4) = 10.73, p = 0.01). Strong emotions were experienced by participants since diagnosed with CD. Anxiety, feelings of concern, sadness, depression and fear have declined and happiness, confidence and being accepting of CD have increased since diagnosis across all years.
Originality/value
This study is one of the first few studies to investigate time since diagnosis and age-related differences in nutritional knowledge, eating habits and QoL of adults diagnosed with CD. Over time, negative emotions could potentially be alleviated with improved knowledge and experience.
