- Gluten-free products in celiac disease: Nutritional and technological challenges and solutions
17.7: Other Food Additives: Beneficial or Dangerous
In celiac patient exposure to even only a small amount of gluten can lead to malabsorption of some important nutrients including calcium, iron, folic acid, and fat-soluble vitamins because of small-intestine inflammation. A strictly followed gluten-free GF diet throughout the patient's lifetime is the only effective treatment for celiac disease; however, elimination of gluten from cereal-based product leads to many technological and nutritional problems.
This report discusses different substitutes to replace gluten functionality and examines the economic and social impacts of adherence to a GF diet. Better knowledge about the molecular basis of this disorder has encouraged the search for new methods of patient treatment.
The new and common GF sources and different challenges encountered in production and consumption of these products and different solutions for improving their properties are discussed in this review. Celiac disease is a chronic inflammatory disorder of the intestine which being asymptomatic to causing severe malnutrition. Gliadin and other prolamins in rye secalins and barley hordeins are toxic for patients with celiac disease.
This paper aims to review the current knowledge on different GF cereals and gluten substitutes used for the production of GF food and the recent advances in molecular knowledge of celiac disease which can help in the development of new methods for celiac therapy.
Hitherto, total lifelong avoidance of gluten ingestion has remained the primary treatment for celiac disease. The overall objective of the GFD is maintaining health through the adoption of a well-balanced diet without using gluten. Observing a strict GFD is not easy, not least because it contributes to the social isolation of patients with celiac disease. In addition, nutritional deficiencies in Vitamins D and B, iron, zinc, calcium, magnesium, and fiber may occur.
Furthermore, developing good-quality GF products could be challenging due to the unique properties of gluten. Several significant properties of rice — it lacks gluten, has a bland taste, is colorless and hypoallergenic, has low levels of protein, sodium, fat, and fiber, and contains high amounts of easily digested carbohydrates — make it suitable for making flour that can be used to prepare GF products.
As rice contains a relatively small amount of prolamin, it is necessary to combine it with some sort of gum, emulsifier, enzymes, modified starch, or dairy products to obtain viscoelastic properties.
Since rice protein cannot participate in the forming of a cohesive dough structure, gelatinized starch plays a role as a binder.
Crackers can be also obtained using either nonwaxy or waxy rice. The high protein, fat, and fiber content of pure oats make them a suitable choice for celiac patients. Therefore, it is necessary to extend strategies that would supply uncontaminated oats. In contrast to the most common grains, pseudocereals are composed mainly of albumins and globulins and contain very little or no storage prolamin proteins;[ 18 ] thus, they are good substitutes for cereal in GF foods.
The nutritional values of wheat and different important GF flour are compared in Table 1. Amaranth consists of small seeds with a nutritional value better than that of any other vegetable, including cereals, and much higher amounts of fiber and minerals than any other GF grain. It has a high amount of lysine, arginine, tryptophan, and sulfur-containing amino acids. Quinoa protein is rich in lysine, methionine, and cysteine. Thus, it is a good complement for legumes, which have low methionine and cysteine.
In addition, quinoa is a relatively good source of Vitamin E and B-group vitamins and has high levels of calcium, iron, and phosphorous. It also has a suitable fatty acid composition. Quinoa's high lipid and low amylase contents make it necessary to have a high shear in extrusion cooking. Buckwheat seeds contain fagopyritols, a type of soluble carbohydrates. Fagopyritols are a source of D-chiro-inositol, a compound that has shown efficiency in patients with noninsulin-dependent diabetes through improved glycemic control.
Buckwheat has a low glycemic index and also shows a beneficial effect on human health, lowering blood pressure and helping cholesterol metabolism. Schoenlechner et al. They found that the firmness and cooking time of amaranth pasta was lower than those for the other flours, while the cooking loss of quinoa pasta was greater than other flours.
Maize's high yields have made it a key crop in ensuring food availability and promoting food security. In addition, products such as curls, puffs, and balls can be produced by extrusion cooking of maize grits or meal, and fried snack products such as tortilla chips can be made from alkaline-processed maize. Breakfast cereals such as flakes, shreds, granules, puffs, or other forms can also be produced from maize. One good source of nutrients, especially fiber, calcium, and other minerals, is millet.
Lysine is a limiting amino acid in millet, while tryptophan and threonine are not deficient. Injera made from millet stales much more slowly than that made from sorghum or other cereals. The main use of teff grain in human food is in injera. Baby foods, snack foods,[ 31 ] and breakfast cereals[ 32 ] are other products made from millet. Germinated, popped, and roasted millet flours have been used along with milk solids, legume flour, and other cereals for the production of complementary and infant foods.
White, pleasant-tasting, and GF flour can be produced from sorghum. Malting can increase lysine and improve protein quality. However, using hydrocolloids could improve sorghum bread's quality.
Some of these studies are presented in Table 2. Sorghum flours have also been used to produce biscuits, granolas, infant food, and snack foods such as crisps and chips.
Since the amounts of Vitamin B, iron, folate, and dietary fiber are not sufficient in most GF flour, the use of chestnut flour seems to be advantageous for improving nutritional value.
Unfortunately, the qualities of chestnut bread, such as volume and color, are not suitable because of weak interactions between components of the chestnut dough,[ 1 ] inadequate starch gelatinization, and high amounts of sugar and fiber.
This flour is more suitable for pastry making. The chia Salvia hispanica L. It attracts a great deal of interest due to its nutritional and functional potential in food and pharmaceutical industries.
Sandri et al. They found no suitable physical and sensory properties when whole chia flour alone was used. They found improved in the dough rheological properties of elasticity, viscosity, and stability up to using 7. Breads produced from legumes such as pea isolate, chickpea flour, soya flour, or carob germ flour showed good sensory profiles and physicochemical characteristics.
Carob germ flour produced batters with good rheological characteristics, but its bread had poor properties. However, chickpea flour and pea isolate kinds of bread obtained good results in all parameters. Application of legume flours, especially lentil, led to lower batter viscosity and consequently higher specific volume than in the control sample. In addition, lentil-enriched cakes showed similar crumb hardness and higher springiness than the control cake.
In terms of nutritional quality, legumes have a higher protein content and protein availability than cereals; this makes legumes as a recommended flour for enriching GF cakes. The decrease in size of carob flour led to a slower rate of firming.
A comparison between GF commercial foods and their gluten-containing counterparts shows that GF food is more expensive. Activities such as baking celiac-specific cereal products, buying foods in large quantities with friends or support-group members, and choosing longer lasting products such as carrots, potatoes, and parsnips, seasonal products, and legumes could help patients to reduce food costs. In addition, damaged villi in celiac patients lead to lactose intolerance because of decreased lactase production, resulting in phosphorus, calcium, and Vitamin D deficiencies.
Using starches and refined flours with low fiber content in GF products leads to inadequate fiber intake. Gluten-containing products have higher folate content than their GF counterparts.
Therefore, fortification of GF products with folate is essential. Pseudocereals such as amaranth, buckwheat, and quinoa are good sources of iron, fiber, and some B vitamins. Recent studies showed a high prevalence of obesity in some celiac patients. A common problem for celiac is bloating, gas, and diarrhea; these may indicate lactose intolerance. Lactose consumption should be avoided and limited for one or more months in this situation until lactase enzyme production recovers.
As mentioned before in detail, the quality, mouth-feel, and flavor of GF products are lower than those of conventional wheat products. The elasticity and extensibility of dough and the volume of the loaves are attributed to gluten. Some of these additives are discussed in [ Table 2 ]. Hydrocolloids can be applied as gluten substitutes in the production of GF food due to their polymeric structure.
Guar gum and xanthan gum are the two most common hydrocolloids used in GF-baked products. HPMC is a cellulose derivative that has a positive effect on the reduction of cholesterol and has also been used in GF breads to increase loaf volume. CMC can increase the porosity and crumb elasticity of bread as well as the overall acceptability of a GF formulation. Some authors have investigated the effect of mixture of hydrocolloids.
They found that a blend of xanthan and guar gum decreased hardness, weight loss, enthalpy of retrogradation, and the change in setback viscosity values of cakes during storage, thus retarding staling.
Starch plays a key role in the texture of many kinds of food products. In some cases, native starch does not provide the functional properties, such as thickening and stabilization, for the production of some special foods.
Therefore, starches used in the food industry are often modified to overcome undesirable changes in product appearance and texture caused by retrogradation or breakdown of starch during processing and storage. Hydroxypropylated starch influences the viscoelastic properties of dough. One of the main factors that could modify the rheological properties of GF modified starch as a part of the dough is water-binding capacity. However, the application of hydroxypropylated starches has not been shown to have a significant impact on pasting characteristics.
This is accompanied by a decrease in average cell size and an increase in average cell number. Acetylation of starch is an important substitution method used for thickening GF food products. Addition of modified starch causes a more elastic crumb structure. A slight decrease in the hardness and chewiness of the crumb was also observable on the day of baking.
Cross-linked starches play an important role in increasing shear resistance and providing viscous batter. Modified starch has shown higher starch gelatinization temperatures and lower viscosity. It has been found that loaves baked with a proportion of resistant starch had a softer crumb than the control sample.
The resulting modified starch, called maltodextrin or dextrin, significantly increases pasting temperature and reduces the viscosity of the obtained pastes. Maltodextrins can attenuate structure and increase deformation sensitivity. The addition of maltodextrins with low dextrose equivalent DE decreases loaf volume and causes the deterioration of bread quality. Maltodextrins with the higher DE positively influence bread volume and have a beneficial effect on crumb hardening during storage. Maltodextrin with the highest DE also effectively reduces the recrystallization enthalpy of amylopectin.

Food Fortification through Innovative Technologies
On December 14, , amendments to nutrition labelling, list of ingredients and food colour requirements of the Food and Drug Regulations came into force. Regulated parties have a five 5 year transition period to meet the new labelling requirements. All prepackaged products with more than one ingredient must declare their ingredients definition and components definition in a list of ingredients [B.
Food processing and nutrition
Wheat flour is a powder made from the grinding of wheat used for human consumption. Wheat varieties are called "soft" or "weak" if gluten content is low, and are called "hard" or "strong" if they have high gluten content. Soft flour is comparatively low in gluten and thus results in a loaf with a finer, crumbly texture. White flour is made from the endosperm only.
Food based interventions include the establishment of horticultural and home garden projects, whereby support is given to strategic target groups to grow certain crops which could alleviate their dietary deficiency. Such activity has received widespread acceptance Arroyave, ; Smitasiri, ; Attig et al. Nutritional education aimed at getting people to improve their eating habits has also demonstrated positive results in selected situations Devadas, ; Soekirman and Jalal, Supplemental feeding programmes have also been very successful Devadas and Saroja, Development or promotion of superior plant varieties in terms of their micronutrient content as well as the identification of processing technologies which maximise vitamin retention are also important food based strategies FAO, ; Bouis, Taken individually any of these interventions is inadequate to eliminate micronutrient deficiency.

The main processing aids used are enzymes. Historically, market trends have developed from the use of ingredients in greater quantities - to obtain specific effects in bread such as fat for crumb softness - to the use of additives at much lower levels max. We will describe the food additives used under each class, individually describing their mode of action and effects on dough rheology, during the breadmaking process, and on product quality. We will also describe the main enzymes currently used, dividing them according to the substrate they act on gluten, starch, lipids, non-starch polysaccharides or NSPS , individually describing their mode of action and effects on dough rheology, during the breadmaking process, and on product quality. Legal aspects will also be addressed. We will conclude with future trends in the use of additives and processing aids in breadmaking. Food Additives.
The chapter aims to approach food fortification naturally as a result of the need for nutritional improvement and therefore underlines sustainable activities that would facilitate effective fortification. The need to fortify food is due to the close link between human, health, and food. The WHO and FAO and other internationally recognized organizations have recognized that there are over 2 billion people worldwide suffering from a variety of micronutrient deficiencies.
