Satiety and consumers' perceptions: What opinions do Argentinian and Brazilian people have about yogurt fortified with dairy and legume proteins?

This study (1) evaluated the perceptions of Argentinian and Brazilian consumers regarding yogurt fortified with dairy proteins, legume proteins, or a combination of both, and (2) determined the satiety expectations of these foods as well as the consumers' intentions to taste and purchase protein-fortified yogurt. A total of 298 Argentinian and 100 Brazilian participants completed an online survey for this study. The free word association technique was used to investigate their perceptions about "satiety" as a verbal stimulus and 6 concepts of yogurt as visual/verbal stimuli (yogurt, set yogurt, skim set yogurt, skim set yogurt with a high content of dairy proteins, skim set yogurt with a high content of legume proteins, and skim set yogurt with a mix of dairy and legume proteins).

Changes in the fatty acid composition in bitter Lupinus species depend on the debittering process.

The evaluation of changes in the fatty acid composition in Lupinus species after the debittering process is crucial to determine their nutritional implications. The aim of this study was to evaluate changes in the fatty acid composition in Lupinus albus and L. mutabilis after the debittering process.

[Determination of the antioxidant capacity of flavonoids in fruits and fresh and thermicaly treated vegetables].

The main objective of the work was to determine the antioxidant capacity of the flavonoids in red apples with and without skin, strawberries, tomatoes and fresh onions and thermally treated: humid heat (boiled and vapor), dry heat (oven) and high frequency (microwaves). The measurement was carried out in a fluorescence spectroscopy and the statistical analysis through the Variance and Test of Duncan. The results indicate that the antioxidant capacity of the flavonoids of red apples with and without skin, strawberries, tomatoes and onions were of 0.

[Chemical composition and digestibility of mote].

White and yellow maize grains (Zea mays amylacea, capia), polished by means of heat treatment with lime and ashes were analyzed (maize for mote); the chemical composition and digestibility in vitro of these grains cooked in boiling water were studied (mote), they were obtained under standardized conditions (laboratory) to compare them with the ones purchased at stores. The composition of nutrients was similar in polished grains, standing out the white ones from laboratory with a protein and sodium content of 9.95 100 g/100 g and 80.
