In vitro digestion of protein and starch in sponge cakes formulated with pea (Pisum sativum L.) ingredients
<p>This is the data used for the figures and supplementary information in the following publication:</p> <p>S. Krause, S. Debon, K. Pälchen, R. Jakobi, C. Bonazzi, B. Rega and T. Grauwet, Food Funct., 2022, 13, 3206-3219. DOI: 10.1039/d1fo03601g</p> <p> </p> <p><strong>Abstract</strong></p> <p>This study investigated the <em>in vitro </em>digestion of purified pea fractions (protein isolate and starch) in sponge cakes when compared to unrefined pea flour and to the whole wheat flour and purified maize starch commonly used in the food industry. Proteins in the wheat cake were hydrolysed more rapidly than those in cakes made with either pea flour or a combination of pea proteins and purified starch. In absolute terms, however, more readily bioaccessible protein was released from these pea cakes (by around 40%). By contrast, cakes containing wheat flour or maize starch were more susceptible to amylolysis compared to those based on pea starch in the form of the purified ingredient or whole flour. This could be attributed to a higher proportion of amylose and resistant starch in the pea cakes as well as structural characteristics that might have decelerated enzyme-substrate interactions. Interestingly, similar digestion patterns were observed regarding the purified pea ingredients and unrefined whole pea flour. It was therefore concluded that pea ingredients, and particularly the less purified and thus more sustainable whole pea flour, are promising plant-based alternatives for use in gluten-free baked products.</p>
In vitro protein and starch digestion kinetics of individual chickpea cells: from static to more complex in vitro digestion approaches
<p>Attention has been given to more (semi-)dynamic <em>in vitro</em> digestion approaches ascertaining the consequences of dynamic <em>in vivo </em>aspects on <em>in vitro </em>digestion kinetics. As these often come with time and economical constraints, evaluating the consequence of stepwise increasing the complexity of static <em>in vitro </em>approaches using easy-to-handle digestion set-ups has been the center of our interest.</p> <p>Starting from the INFOGEST static <em>in vitro </em>protocol, we studied the influence of static gastric pH <em>versus </em>gradual gastric pH change (pH 6.3 to pH 2.5 in 2 h) on macronutrient digestion in individual cotyledon cells derived from chickpeas. Little effect on small intestinal proteolysis was observed comparing the applied digestion conditions. Contrary, the implementation of a gradual gastric pH change, with and without the addition of salivary α-amylase, altered starch digestion kinetics rates, and extents by 25%. The evaluation of starch and protein digestion, being co-embedded in cotyledon cells, did not only confirm but accounted for the interdependent digestion behavior. The insights generated in this study demonstrate the possibility of using a hypothesis-based approach to introduce dynamic factors to <em>in vitro</em> models while sticking to simple and cost-efficient set-ups.</p> <p> </p> <p>The data used for the graphs in the paper: K.
