The market for gluten-free products is increasing with an estimated 7.6% annual growth rate from 2020 to 2027. It has been reported that most gluten-free products, such as bread, cookies, and pasta, contain great amounts of simple carbohydrates and are low in fiber and protein, affecting people\'s health. Pulses such as common beans, chickpeas, lentils, and peas have been studied as an alternative for developing gluten-free products because of their high protein and fiber content. In addition, they contain bioactive compounds with nutraceutical properties, such as phenolics, saponins, dietary fiber, and resistant starch, among others. Most studies carried out with pulses in vitro and in vivo have displayed health benefits, proving that pulse-based food products are better than their counterparts, even those containing wheat, with proper sensory acceptance. This work reviews pulse\'s nutritional and nutraceutical properties to promote the development and consumption of gluten-free products and improve their formulations to promote people\'s health.

Celiac disease is an immune-mediated disorder caused by the ingestion of gluten proteins. The gluten-free diet is currently the only therapy to achieve the symptoms\' remission. Biotechnological approaches are currently being explored to obtain safer and healthier food for celiacs. This article analyzes consumer awareness and acceptance of advanced biotechnologies to develop gluten-free products. An online snowball sampling questionnaire was proposed to 511 Italian participants, selected among celiac and non-celiac people, from December 2020 to January 2021, during the second wave of the COVID-19 pandemic. Overall, 64% of respondents favor food biotechnology, as long as it has benefits for health or the environment. Moreover, biotechnology perception differs according to education level and type. A total of 65% of the survey participants would taste gluten-free products obtained through a biotechnological approach, and 57% would buy them at a higher price than the current market price. Our results show a change in public opinion about the usefulness of food biotechnology and its moral acceptability compared to 20 years ago. However, the study of public opinion is very complex, dealing with individuals with social, economic, and cultural differences. Undoubtedly, the scientific dissemination of genetic biotechnologies must be more effective and usable to increase the level of citizens\' awareness.

Cereal-based foods have been essential elements in nutrition throughout history. Recently, there has been an increasing interest in the application of innovative strategies to improve technological and nutritional properties of dough-based cereal products. Literature studies indicate that the integration of vacuum technology into baking and noodle industry can significantly enhance the quality and feasibility of final products. The vacuum has direct impact on gluten network, gas distribution and interaction of components in food matrix, especially due to aerated structure of dough systems. In this respect, this review for the first time presents a comprehensive evaluation regarding to use of vacuum technology in processing steps (i.e., mixing, baking, and cooling) of dough-based products in light of recent studies. The implementation of vacuum in the processes provide desired impacts on productivity and profitability for manufacturing industries. Vacuum application provides many advantages including improved product quality, nutritive value, extended shelf life, and reduced energy consumption.

Although whole grain (WG) sorghum is affordable and a healthier alternative to gluten-free pastas (GFPa), sorghum diversity requires evaluation for application in pasta. We aimed to develop GFPa using six sorghum hybrids. White commercial flour (WCF) and sorghums with brown (BRS 305 and 1167048), red (BRS 330 and BRS 332), and white (CMSXS 180) pericarp colors. Total phenolic content (TPC), total condensed tannins (TAN), total antioxidant activity (TAA-FRAP and DPPH), resistant starch (RS), cooking properties, texture, and sensory evaluation were carried out in sorghum pasta. The statistical analyses were ANOVA, Tukey and Friedman test, and multiple factorial analyses. Brown sorghum GFPa showed the best results for bioactive compounds (RS (1.8 and 2.9 g/100 g), TPC (69.9 and 42.8 mg/100 g), TAN (16.9 and 9.4 mg proanthocyanidin/100 g), TAA for FRAP (305 and 195 mM Teq/g), and DPPH (8.7 and 9.0 mg/mL)), but also the highest soluble solids loss (8.0 g/100 g) and lower flavor acceptance for BRS 305. BRS 332 was highlighted for its higher flavor acceptance and intermediary phenolics content. The most accepted pasta was obtained with WCF, and the least accepted with the brown BRS 305. Sweetness (SWE), soluble starch (SS), and DPPH were associated with liking. The main negative variables were WG_flavor, brown color, FRAP, sandy surface (SAN), WG_odor, and TAN. Sorghum hybrids of different pericarp colors are feasible for GFPa production, leading to differences in pasta quality. SAN and GRA, associated with disliking in antioxidant-rich GFPa, could be improved by milling process adjustments. Increasing the SS proportion and SWE with flavors can contribute to the balance between liking and nutritional advantages.

The food industry generates a great amount of food waste and by-products, which in many cases are not fully valorized. Press cakes, deriving from oilseeds extraction, represent interesting co-products due to their nutritional value, high biopolymers content, and the presence of bioactive phytochemicals. Gluten-free breads (GFBs) are products that have disadvantages such as unsatisfactory texture, low nutritional value, and short shelf life, so natural additives containing proteins and hydrocolloids are in demand to increase GFBs value. In this study, extract from flaxseed by-product (FOCE-Flaxseed Oil Cake Extract) was used to replace water (25-100%) in GFBs formulations and their nutritional value, antioxidant properties, and sensory features were investigated. The results showed that GFBs with FOCE had an elevated nutritional and nutraceutical profile (up to 60% more proteins, significantly increased K, Mg, and P levels). Moreover, the addition of FOCE improved the technological parameters (increased specific volume, number of cells and height/width ratio, reduced density, average size, and perimeter of cells), antioxidant potential, and overall sensory quality of GFBs. This study showed an encouraging way of using a by-product that, due to its high content of proteins, polysaccharides, minerals, and antioxidants, can add value to GFBs.

Gluten, a protein fraction from wheat, rye, barley, oats, their hybrids and derivatives, is very important in baking technology. The number of people suffering from gluten intolerance is growing worldwide, and at the same time, the need for foods suitable for a gluten-free diet is increasing. Bread and bakery products are an essential part of the daily diet. Therefore, new naturally gluten-free baking ingredients and new methods of processing traditional ingredients are sought. The study discusses the use of additives to replace gluten and ensure the stability and elasticity of the dough, to improve the nutritional quality and sensory properties of gluten-free bread. The current task is to extend the shelf life of gluten-free bread and bakery products and thus extend the possibility of its distribution in a fresh state. This work is also focused on various technological possibilities of gluten-free bread and the preparation of bakery products.

In the past decades, food products and beverages made from gluten-free cereals were initially created for certain groups of people who experience gluten-related disorders such as wheat allergies, gluten ataxia, non-celiac gluten sensitivity, and the most well-known, celiac disease. Nowadays, the consumption of gluten-free products is not only restricted to targeted groups, but it has become a food trend for normal consumers, especially in countries such as the UK, the US, and some European countries, who believe that consuming a gluten-free product is a healthier choice compared to normal gluten-containing products. However, some research studies have disapproved of this claim because the currently available gluten-free products in the market are generally known to be lower in proteins, vitamins, and minerals and to contain higher lipids, sugar, and salt compared to their gluten-containing counterparts. The use of other gluten-free cereals such as sorghum, millet, and teff as well as pseudo cereals such as buckwheat and quinoa has gained significant interest in research in terms of their various potential health benefits. Hence, this review highlights the potential health benefits of some gluten-free cereals and pseudo cereals apart from corn and rice in the last decade. The potential health benefits of gluten-free products such as bread, pasta, crackers, and cookies and the health benefits of some other non-alcoholic beverages made from gluten-free cereals and pseudo cereals are reported.

Celiac disease (CD) is a chronic autoimmune disorder of the small intestine, whose only effective treatment is a gluten-free diet (GFD). It is characterized by the atrophy of the intestinal villi that leads to altered nutrient absorption. This study describes the nutritional imbalances which may be found in adults with CD following a GFD. During the first year of treatment, deficiencies will overcome as the intestinal mucosa recovers. Thus, biochemical data will show this progression, together with the decrease in symptoms. In contrast, in the long term, when a strict GFD is followed and mucosal recovery is achieved, analyzing nutrient intake makes more sense. Macronutrient consumption is characterized by its low complex carbohydrate and fiber intakes, and high fat (especially SFA) and sugar intakes. This profile has been related to the consumption of GFP and their nutritional composition, in addition to unbalanced dietary habits. The most notable deficiencies in micronutrients are usually those of iron, calcium and magnesium and vitamin D, E and some of group B. It is necessary to follow up patients with CD and to promote nutritional education among them, since it could help not only to achieve a gluten free but also a balanced diet.

UNASSIGNED: Celiac disease is a chronic autoimmune disease triggered by gluten exposure in genetically predisposed individuals. A life-long intake of a gluten-free (GF) diet is required for its management. Wheat, rye and barley are eliminated in a GF diet and the nutritional adequacy of the diet has been questioned. In Norway, cereals and bread constitute a key role of the diet and are the main source of fiber intake. Gluten restrictions may therefore offer important implications for nutrient adequacy especially linked to fiber intake in people with celiac disease.
UNASSIGNED: The aim of the study was to investigate the nutritional quality and price of GF products and compare with gluten-containing counterparts available at instead of in the Norwegian market.
UNASSIGNED: The macronutrient content of 423 unique GF products were compared with 337 equivalents with gluten. All products were selected from grocery stores and web-based shops, with the aim of including as many GF products as possible. Listed macronutrients content and price in 11 different food categories were compared to gluten-containing counterparts with Wilcoxon signed rank test.
UNASSIGNED: The GF products contained less protein and fiber, and higher content of saturated fat, carbohydrate and salt compared to the gluten-containing products. The total amount of fat was not different between the groups. A similar pattern was found within several of the food categories. More gluten-containing products met the nutrition claim \"high in fiber\" (fiber > 6 g/100 g) compared to the GF products. The price of the GF products was higher; ranging from 46%-443% more expensive than the gluten-containing products.
UNASSIGNED: GF products are less nutritious and have a higher price compared to equivalent gluten-containing products. Knowing that an unhealthy diet is the most important risk factor for developing non-communicable diseases, the nutritional quality of a GF diet needs to be addressed and should be improved.

Special diets are used for the treatment and prevention of diseases of the digestive system, taking into account individual food intolerance and possible allergic reactions. The monotony of the diet due to the limited range of recommended foods and dishes negatively affects both the effectiveness of the treatment of gluten intolerance, and the provision of the body with essential and replaceable nutrients. The aim of this study was to determine the selenium content in the flour of gluten-free crops (rice, corn, buckwheat and amaranth), their mixtures, as well as in dishes (pancakes) from a mixture of amaranth and buckwheat flours. Material and methods. The following raw materials were used in the study: amaranth flour, unboiled buckwheat groats, whole grain rice flour and corn flour. By mixing the components in a laboratory mixer, dry gluten-free compositions were obtained: a mixture of amaranth flour and flour from native buckwheat; a mixture of amaranth and rice flour and a mixture of amaranth and corn flour in the ratio of 1:2 and 1:1; and a mixture of amaranth, buckwheat and corn flour in equal proportions. In laboratory baking of pancakes, mixtures of amaranth flour and flour from native buckwheat were used. The selenium content was determined by atomic absorption spectroscopy with electrothermal atomization after wet mineralization of the samples. Results. The results of the study showed that amaranth, buckwheat and corn are rich sources of selenium. The most valuable source of selenium was amaranth flour (515 μg/kg). Selenium content in native buckwheat flour and corn flour was 405 and 458 μg/kg, respectively. The lowest selenium content among the studied crops was found in rice flour (135 μg/kg). Selenium content in flour mixtures of the studied cultures ranged from 258 to 522 μg/kg. The highest values of selenium content were observed in mixtures of amaranth with corn flour (516-522 μg/kg). The lowest content of this trace element was found in mixtures containing rice flour (from 258 to 325 μg/kg). Selenium content in pancakes made from mixtures of amaranth flour and native buckwheat flour varied from 290 to 326 μg/kg. The calculation showed that the consumption of a portion of pancakes (50 g) by school-age children will satisfy their daily requirement for selenium by 7.3-8.1%. Conclusion. Regular inclusion of amaranth-based foods in the diet of children with gluten intolerance can positively affect the elimination of selenium deficiency.
