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.

Definition of dietary fibre, physiological relevance, health benefits and analytical aspects. The differences determined in fat values may be also attributable to the corn variety and conditions prevailing during nixtamalization process.
Retrieved 9 January J Agric Food Chem ; As shown in Table Iall of the samples contained appreciable amounts of fiber-associated RS, xlmidon levels varied between 3.
Effect of storage time on in vitro digestibility and resistant starch content of nixtamal, masa and tortilla. Am J Clin Nutr ; This apparent discrepancy may be consequence of the accuracy differences existing among resistant starch methods of analysis 7although the rrsistente of varietal or processing conditions cannot be ruled out.

One review estimated that the acceptable daily intake of resistant starch may be as high as 45 grams in adults, resisstente an amount exceeding the total recommended intake for dietary fiber of 25—38 grams per day. American Association of Cereal Chemists A. Brit J Nutr ; Asp N-G Dietary carbohydrates: Soluble carbohydrates decreased with the storage time; samples A and B showed the highest values whereas C and D exhibited the lowest ones. When the behavior of this tortilla sample was compared along the different storage times Fig.
Also, despite the similar IDF content in yellow and green peas, their corrected IDF figures were considerably different. Carbohidratos en Alimentos Regionales Latinoamericanos.
Nutritional implications of resistant starch. Food and Nutrition Board. Moreover, fiber and RS may also exhibit different fermentation product patterns Nyman, Classification and measurement of nutritionally important starch fractions.
rfsistente The differences found in starch bioavailability in tortillas may be mainly due to both corn variety and nixtamalization conditions used in each tortilleria for masa preparation. RRS values between 2. It is therefore important to make the appropriate choice of corn variety for obtaining major or minor AS content apmidon tortillas.
Protein 2,3 Ash 2. In general, processes that break down structural barriers to digestion reduce resistant starch content, with greater reductions resulting from processing.
Ash content usually does not vary with the nixtamalization process 29, Once in the laboratory, the masa was quickly molded by pressure and extruded into thin circles to obtain 1mm-thick “tortillas”. Classification by chemistry and physiology. Starch in raw foods is not easily digested, exhibiting variable levels of RS2 fractions. M and Asp NG. Differences were found in moisture level among the different tortilla samples, which may be due to either corn variety or, more likely, to variations in the nixtamalization process, as all tortillas were cooked under the same temperature and time conditions.
Resistant starch – Wikipedia
However, leaching of partly hydrolyzed starch fractions during grain nixtamalization cannot be ruled out. Nutritional composition of corn and flour tortillas. Hence, in spite of the current tendency to integrate all indigestible fractions to the dietary fiber concept Saura-Calixto et al.
Such figures may be employed to calculate starch-corrected dietary fiber values for these edible pulses. RS2 from potato starch and green banana starch maintain their resistance as long as they are consumed raw and unheated. Rooney; Lusas, Edmund W. Physiological Roles and Food Applications”. Nowadays, table tortillas are highly popular in United States and, to some extent, also in Canada and some European countries 3. Freshly cooked sample B showed the highest values and the A tortillas the lowest ones.
