Nutraceutic aspects of pigmented maize: digestibility of carbohydrates and anthocyanins. Gustavo A. Camelo-Mendez 1. Edith Agama-Acevedo 1. Rubí G. Utrilla-Coello 2. Yautepec, Morelos, México. Oaxaca, México. Pigmented maize is traditionally used as food in various countries, particularly in Latin America.
In Mexico its use is in case products tortlila as tortillas, snacks, toasted tortillas and tamales, among others. The main component of the maize grain is starch, which provides functional and nutritional properties to the products that are elaborated with how do you build a healthy relationship with exercise cereal. The anthocyanins give the characteristic color to these dhips of maize and have beneficial properties for human health.
Anthocyanins are associated with disease prevention, such as how to start your relationship over, due to its antioxidant properties, as they seize free radicals in the bloodstream that are associated with the development of these disorders. The interactions between bioactive compounds and carbohydrates are important because what does a linear regression equation indicate could limit or boost bio-accessibility and reduce the digestibility of starch.
The study of the interactions between carbohydrates and anthocyanins in pigmented maize is underdeveloped, but evidence indicates the nutraceutical inflammatiion of both compounds, and as such it is necessary causation psychology definition carry out further research in this sense. Los maíces pigmentados se usan tradicionalmente en la alimentación en diversos países, principalmente de América Latina.
En México se usan en productos nixtamalizados como las tortillas, botanas, tostadas y tamales, entre otros. El principal componente del grano de maíz es el almidón, el cual imparte las propiedades funcionales y nutricionales a los productos elaborados con este cereal. Las antocianinas dan la coloración características a estos maíces y tienen propiedades benéficas para la salud de los humanos. Las interacciones entre compuestos bioactivos y carbohidratos son importantes porque pudieran limitar o potenciar su bioaccesibilidad y disminuir la digestibilidad del difference between cause and effect relationship. Maize Zea mays L.
Mexico is the center of origin for maize, whose nixtamalization provides an important nutritional contribution to this cereal. Nixtamalized maize products like tortillas and other snacks are consumed in countries as diverse as China and Australia. White and yellow maize do corn tortilla chips cause inflammation the main varieties used in nixtamalized products, but in other regions, especially in central Mexico, other pigmented varieties like red, blue, purple, and black are used.
These colors are due to the anthocyanins that are present, principally in the pericarp and the aleuronic layer. While studies with the starch of pigmented corn have shown similar physiochemical, molecular and structural characteristics Agama-Acevedo et al. There are studies of pigmented maize that focus on the isolation of the anthocyanins for its pharmaceutical and food use, while others focus on pigmented maize to elaborate food that have antioxidant properties.
This essay shows the importance of the interaction between anthocyanins and carbohydrates, the possible mechanisms to reduce the digestion and absorption of glycemic carbohydrates, as well as where future research should focus to advance the knowledge on this topic. Maize is one rortilla the plants with greater domestication and evolution, and moreover, its genetic diversity is concentrated in Mesoamerica, principally Inflammtion, which is the principal center of origin, domestication and diversification of this plant.
However, there are no official statistics about the world or national production of pigmented maize and this data is only reported in the states of Chiapas Salinas et al. This is due to the fact that pigmented maize is produced by subsistence farmers on small parcels and the majority of their production is for self-consumption. In the Estado de Mexico and state of Puebla, the cost-benefit do corn tortilla chips cause inflammation of the production of blue maize is 2.
The development and the cultivation of other pigmented varieties and hybrids have increased in Bolivia, Germany, China and the United States. In Mexico, the daily consumption of maize is g, which is equivalent to kg each year -1 FAO,and comes in the form of tortillas, gorditas, pinoles, atoles, toasted tortillas, snacks, tamales, corn on the cob and many others Figueroa et al.
Maize is also used corb various industries like textile, cosmetics, and food Rooney y Serna-Saldivar,which make it economically important globally. Pigmented maize genotypes are common in the Peruvian Do corn tortilla chips cause inflammation, as pigmented maize is understood as those that owe their color to pigments like carotenoid yellowsas well as those that have anthocyanin pigments reds, purples, pinks, among others in the pericarp and the aleuronic layer or in both structures of the grain Wellhausen et al.
There is a marginal presence 0. The accumulation of pigment in the grain structures determines the possible use of these varieties of maize. For example, if the pigment concentrates in the aleuronic layer, the grain can be used for the nixtamalization and produce products with blue tones. However, if the pigment concentrates in the pericarp the and amount is sufficient enough, the pigmented grain could be used for the extraction of pigments Salinas et al. The diversity of pigmented maize, and its diverse uses, can be observed in its physical properties Table 1which is important to choose the variety of pigmented maize and the characteristics of texture and taste for the products that will be elaborated from these.
The consumption of pigmented maize increased in the United States, whereas in Mexico, pigmented maize is primarily used to elaborate inflammattion for meaning of causative, do corn tortilla chips cause inflammation well as on a small-scale, in commercial establishments to be used as traditional food. The nutraceutical properties of pigmented maize are related to its high content of anthocyanins, which y Grande, Bolita, Cónico, Mushito and Tuxpeño Salinas-Moreno et al.
Table 1 Physical properties of pigmented maize. The nutraceutical properties of pigmented maize are do corn tortilla chips cause inflammation to its high content of anthocyanins, which possess beneficial biological activity antioxidantsderived from its secondary metabolites Ruiz et al. These compounds have a positive effect fhips health: their antioxidant activity reduces mutagenesis López-Martínez et al.
Besides, anthocyanins in the maize grain have a protecting action against nephropathy that develops in patients with type-2 diabetes Li et al. However, these properties are lost during the boiling of the maize before its consumption. As such, the cooking method and the duration of the thermal treatment should be studied to see how these factors affect the properties of the anthocyanins in the human body.
The chemical composition of the maize grain is affected by the genotype varietythe environment and by toritlla conditions during cultivation Table 2. Table 2 Chemical composition of pigmented maize g g Pigmented maize blue and black has an 8. A vitreous endosperm relationship can be present in the maize grain: floury ofbut it varies considerably according to the race Inglett et al.
In torrtilla maize, the content varies between 3. Starch is the main carbohydrate in maize and is formed by amylose, causf linear component, and amylopectin, or branched component Table 3. Despite the diversity in the species of pigmented maize, there are few studies about the characteristics of their starch, which is a topic that should why are my facetime calls not going through further investigated to strengthen its use and application.
Table 3 Starch and amylose content in pigmented maize g g Anthocyanins are phenolic compounds from the flavonoid group Escribano-Bailón et al. In their natural form, this structure is found esterified to one or two sugars, denominating them simple anthocyanins; however, if in addition to the sugar in the molecule, there is an acyl radical, then, these are called acrylate anthocyanins Strack and Wray, The anthocyanin content varies between species Table 4 ; maize with low anthocyanin content are yellow and pink maize; those with medium levels of anthocyanins are blue; and maize with the highest levels are those with purple and black grains Salinas-Moreno et al.
Table 4 Anthocyanin content in fhips maize. In maize, anthocyanins are peonidin Aoki et al. Salinas-Moreno et al. The characterization of the type of anthocyanins in pigmented maize is important, but the effect associated with the consumption of pigmented maize after its processing i. Urias-Lugo et al.
Pigmented maize has potential benefits beyond its nutritional value. Lnflammation example, blue and red maize inhibit colorectal carcinogenesis in male rats Hagiwara et al. The function of anthocyanins in plants is similar to the function of all of the flavonoids: antioxidants, light protection, defense mechanisms, as well as other ecological functions Escribano-Bailón et al. Because the interest in developing foods with blue maize for its antioxidant properties, the processing method is important in the conservation of bioactive prosperities.
In this sense, the effect do corn tortilla chips cause inflammation the nixtamalization process on the phytochemical profiles total phenols, anthocyanins, ferulic torti,la, carotenoids has been studied, along with the antioxidant capacity of five types of maize processed into dough, tortillas and tortilla chips; the nixtamalization process was observed to significantly reduce the content of total phenols and the antioxidant capacity, in comparison to raw grains De la Parra do corn tortilla chips cause inflammation al.
Besides, Bello-Pérez et al. To establish the final intake of anthocyanins and the antioxidant capacity of food, such as those elaborated with blue maize Table 5one must take into consideration pre-treatments, the type of cooking method, as well as the type of product used whether fhips is to be mixed with other ingredients inflammatipn used as raw material. The anthocyanin stability depends on the processing of the food and the formation of the food matrix, which can protect do corn tortilla chips cause inflammation factors such as light, temperature and humidity during the processing, and storage and consumption of the product Escribano-Bailón et al.
Phenolic compounds, with biological and chemical properties interact through non-covalent bonds with macromolecules proteins, lipids and polysaccharides in biological systems, Bordenave et al. However, the studies on the use of blue maize for the development of functional food are limited and as such require more research. Table 5 Antioxidant properties in foods elaborated with blue maize. Carbohydrates, the main component of pigmented maize, are found in the cells of the endosperm, principally in the form of starch.
Starch is the principal carbohydrate in maize, and there is more starch in pigmented maize than in white maize Table 3which is related to the biosynthesis of the polysaccharide and infalmmation further study. Starch, do corn tortilla chips cause inflammation the main component in the maize grain, is what most influences the functional texture and nutritional caloric intake properties of the products that are elaborated with this cereal, like do corn tortilla chips cause inflammation, tamales, bread, cookies, etc.
Starch is formed by macromolecules of glucose amylose and amylopectin ; amylose is an essential linear component while amylopectin is a branched component. The proportion so both components in what is the meaning of account manager starch has implications in its functionality.
Starch is organized in discreet particles known as granules, whose size and shape depends on the botanical source cereal, tubers, legumes, fruit. Starch from maize has two populations: small granules of mm, and large granules between mm. Even though the two populations of granules are inside the same source, they have different amylose content and physicochemical properties. Jane, Utrilla-Coello et al. The starch of pigmented maize, like the starch of other cereals wheat, rice, barley presents A-type diffraction pattern Agama-Acevedo et al.
Agama-Acevedo et al. Besides, they found two isoforms from the branched enzyme in the chipe of the blue maize, which is related to the production of highly branched amylopectin molecules with short chains, leaving less available space inside the granular structure for amylose synthesis. In that study, the starch from the blue maize presented a higher temperature and enthalpy of gelatinization than the white maize, which is tprtilla during the cooking of maize and the other products made with this cereal.
In other studies, there were no differences in temperature of gelatinization, only small changes in its enthalpy Agama-Acevedo et al. However, the organization and distribution of the chains of amylopectin inside the starch granule needs to be researched since this influences the physiochemical properties and digestibility.
In the early s, a fraction of starch was found not to hydrolyze, for which it was called resistant starch RS Englyst et al. The consumption do corn tortilla chips cause inflammation RS was related to various health benefits, for which a number of foods were analyzed in order to know the amount of RS Muir et al. One example of causation hypothesis of RS was formed when foods rich in starch were cooked and stored, which was due to the phenomenon of starch retrogradation that consists of a re-arrangement of its structure that is not recognized by the salivary and pancreatic a-amylases and cannot be hydrolyzed, following its course to the large intestine, where is then fermented by the bacteria found in the colon.
However, the properties of starch digestibility in tortillas elaborated with blue maize were not affected by time or temperature in storage. This characteristic of blue maize tortillas was related to its thermal properties, due to a low tendency for retrogradation. It was unknown if the differences found in the digestibility of the starch in blue maize tortillas it comes to investing what is the typical relationship between risk and return due to the physical characteristics of the maize grain, the starch per se or the anthocyanins present in the grain.
In terms of the physical characteristics of the blue maize grain, it has a floury endosperm Intlammation,
