Both raw and retrograded starch decrease serum triacylglicerol concentration and fat accretion in the rat.

Resistant starch

As shown in Table Iall of the samples contained appreciable amounts of fiber-associated RS, whose levels varied between 3.

An evidence-based approach to dietary phytochemicals. In general, moisture content in the same kind of tortilla did not change with the storage time; confirming that the poly-ethylene bags where the tortillas were stored restricted water losses.

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


The in vitro rate of hydrolysis was measured using hog pancreatic amylase, according to Holm et al. Journal of the Science of Food and Agriculture. Starch has been consumed by people and animals for thousands of years.

Gordon DT Dietary fiber definitions at risk. Since commercially available dehulled green and yellow peas are often consumed in Venezuela, these coat-free seeds were also evaluated. The values of total starch content TS are presented in Table 2. J Food Sci ; 49, It is noteworthy that RS contents in the four common bean Phaseolus vulgaris varieties analyzed fell within a narrow interval 5.

In general, hydrolysis rate fell as storage time increased, this pattern relates to RRS formation during tortilla storage. 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.

Cereal Chem ;80, Resistant starch is considered both a dietary fiber and a functional fiber, depending on whether it is naturally in foods or added. Starch consists of amylose and amylopectin [23] which affect the textural properties of manufactured foods. Nowadays, table tortillas are highly popular in United States and, to some extent, also in Canada and some European countries 3.

It is therefore important to make the appropriate choice of corn variety for obtaining major or minor AS content in tortillas.


RS3 are retrograded starches, which may be formed in cooked foods that are kept at low or room temperature J Cereal Sci ;3, Complex Carbohydrates in Foods. Insoluble dietary fiber residues were prepared in duplicate for each legume, following the enzymatic method of Prosky et al.

Tovar J, Bjorck I. Asia Pac J Clin Nutr. Also, despite the similar IDF content in yellow and green peas, their corrected IDF figures were considerably different.

These masas were obtained according to the traditional method redistente produce nixtamal, which shows minor differences among the different “tortillerias”; such variations relate mainly to the length of the steeping step 4. The in vitro a -amylolysis reaction of tortillas is represented in Figure 1. Am J Clin Nutr ; Digestion of carbohydrate from white beans Phaseolus vulgaris L.
