Resistant starch (RS) is starch, including its degradation products, that escapes from digestion in the small intestine of healthy individuals. Resistant starch. Efecto del tiempo de almacenamiento sobre el contenido de almidón resistente y la tasa de digestión in vitro de tortillas elaboradas con masas comerciales de.

In general, total resistant starch RS values in tortilla samples A, B and Allmidon increased with storage time ; this in accordance with the fact that tortillas were cold stored, thus favoring the retrogradation phenomenon RRS.
Critical Reviews in Food Science and Nutrition. Nutr Res Rev ;9: Starch availability in vitro and in vivo after flaking, steam-cooking and popping of wheat.

The main classification of RS has been proposed by Englyst et al. Resistant starch has a small particle size, white appearance, bland flavor and low water-holding capacity.
Characterization of comercial nixtamalized flours. Starch Prebiotics nutrition Food additives. Almudon values of total starch content TS are presented in Table 2. Journal of Agricultural and Food Chemistry.
Tortilla resiztente were elaborated by four small commercial factories in Mexico, employing masas prepared with the traditional nixtamalization process. In all samplesAS values decreased with storage time.
One review estimated that the acceptable daily intake of resistant starch may be as high as 45 grams in adults,  an amount exceeding the total recommended intake for dietary fiber of 25—38 grams per day. Resistant starch are found naturally in cereal grains, seeds, legumes and tubers and, in the food industry, it is in products associated with baking, pastries, cookies and extruded cereals.
Epub 21 Oct Digestion of carbohydrate from white beans Phaseolus vulgaris L. The reduction in AS content during storage may be explained by the formation of resistant starch due to the retrogradation phenomenon that takes place when a cooked starch product is cold-stored 8. Starch almidin and colorectal cancer risk: Moreover, fiber and RS may also exhibit different fermentation product patterns Nyman, Starches with high amylose content generally have increased resistant starch.
After baking control or following the corresponding storage period, samples were frozen in liquid nitrogen, freeze-dried and stored at room temperature in sealed plastic containers. Asia Pac J Clin Nutr. Also, when a single tortilla sample was compared throughout the different storage times, lower DRs were determined in samples subjected to prolonged storage, which is related to the concomitant increase in RRS.

It is therefore important to make the appropriate choice of corn variety reeistente obtaining major or minor AS content in tortillas. Selective nixtamalization of fractions of maize grain Zea mays L. Complex Carbohydrates in Foods.
Carbohydr Polym ;43, Resistant starch is considered both a dietary fiber and a functional fiber, depending on whether it is naturally in foods or added. Processing may affect the natural resistant starch content of foods. Fiber residues were analyzed enzymatically for starch remnants, i.
The highest values were recorded in sample A and the lowest ones in sample C. Food Chem ;56, Ash, protein and fat were analyzed according to AACC 21 methods, andrespectively ApartadoCaracas A. Incomplete digestion of legume starches in rats: Formation and measurement of starch that survives exhaustive digestion with amylolytic enzymes during the determination of dietary fibre”. The following legume seeds were analyzed: However, they are lower than those reported by Campas-Baypoli et al. A RRS value of 2.
Nutritional composition of corn and flour tortillas. RS contents in the four common bean Phaseolus vulgaris varieties analyzed fell within a narrow interval 5. American Journal of Agricultural and Biological Sciences. Samples were stored at 4 o C for up to 72 hours and their chemical composition and in vitro starch digestibility features were evaluated.
Resistant starch was measured by two different protocols: However, leaching of partly hydrolyzed starch fractions during grain nixtamalization cannot be ruled out. Influence of genotype and processing on the in vitro rate of starch hydrolysis and resistant starch formation in peas Pisum sativum L.
Resistant starch – Wikipedia
A randomized complete design with three replications was used to analyze changes during tortilla storage. Gordon DT Dietary fiber definitions at risk. Physicochemical changes of starch during maize tortilla production. Resistant starch associated to fiber, i. Employing previously reported dietary fiber values, RS levels recorded for each legume were used to calculate starch-corrected insoluble dietary fiber.
