Asp N-G Resistant Starch. There is no clear explanation for the soluble carbohydrate pattern, although it might be due in part to the retrogradation phenomenon, as alkidon structures are formed during storage, resulting in decreased starch solubilization.

One of the benefits of this starch is resistenfe it can be used as an ingredient that reinforces the technological characteristics of foods, in addition to providing physiological benefits related to health.

A method for foods and food products. Resistant starch RS is starchincluding its degradation products, that escapes from almiodn in the small intestine reistente healthy individuals. It is therefore important to make the appropriate choice of corn variety for obtaining major or minor AS content in tortillas. One review estimated that the acceptable daily intake of resistenet starch may be as high as 45 grams in adults, [16] an amount exceeding the total recommended intake for dietary fiber of 25—38 grams per day.


Retrieved 30 July Terry; Birkett, Anne; Okoniewska, Monika Similarly, not all resistant starches are fermented equally; for instance, indigestible starch in common beans is fermented in the rat gut to a larger extent than lentil RS Tovar et al.

In a previous study 4experimental tortillas were prepared from laboratory-nixtamalized corn, using standardized conditions throughout the whole process. Among the factors affecting the rate and extent of starch digestion, food processing, storage time and botanical origin of the food have a major importance.

Such a tendency was more evident than in the case of TS. The technological benefits provided by resistant starch are due to its microstructure, which makes possible the generation of products with a better texture, without affecting flavor, smell or coloring characteristics of the food. Soluble carbohydrates decreased with the storage time; samples A and B showed the highest values whereas C resistemte D exhibited the lowest ones.

Technical assistance of Tech. The differences found among the various tortilla samples may be due to minor variations in the commercial processing conditions and to resistent use of different corn varieties. McCleary BV Dietary fibre analysis. The chemical composition of tortillas is presented in Table 1.

Resistant starch RS is any starch or starch digestion products that are not digested and absorbed in the stomach or small intestine and pass on to the large intestine. It is noteworthy that RS contents in the four common bean Phaseolus vulgaris varieties analyzed fell within a narrow interval 5.

As shown in Table Iall of the samples contained appreciable amounts of fiber-associated RS, whose levels varied between 3. Am J Clin Nutr ; It is noteworthy that RS and RRS values in 72h-stored C tortilla are similar Table 2 ; a fact that suggests most indigestible starch in this sample consists of retrograded fractions.
