    Reformulation of snacks offered to children and adolescents at school kiosks: is this strategy enough or just the tip of the iceberg?
    (2024-08-29) Lingiardi, Nadia; Arribas, Alberto; Arriola, Ileana; Godoy, Ezequiel; Reinheimer, María Agustina
    Several studies have reported high overweight and obesity incidence among schoolchildren and adolescents, who mostly consume packaged snacks with critical nutrients exceeding the criteria of international profiling systems during school breaks. Then, the objectives of this work were to reformulate a snack consumed by Argentinian schoolchildren and adolescents (aged 6-13 years) to decrease its critical nutrient contents and to determine if this product would still be accepted. Chocolate chip vanilla cookies were selected for reformulation considering each recommended cut-off point for critical nutrients, since a prohibition of products with warning octagons being offered at schools would come into effect in Argentina. These cookies received good acceptability scores (above 3 of 5 points) and would be consumed by 8 of 10 schoolchildren in a sample of 200 participants. These findings underscore the importance of legislation promoting awareness of healthier eating habits and increasing the availability of healthier food 30 options in schools.

    Protein recovery from yellow peas (Pisum sativum L.) for enhanced processing sustainability and functional properties.
    (2024) Guraya, María Ángeles; Andrín, María Nieves; Batres, Rocío; Torresi, Pablo Antonio; Godoy, Ezequiel; Reinheimer, María Agustina
    This research focuses on sustainable protein recovery methods from a new yellow pea variety by examining alternative pH-shifting processes. The study focuses on reducing water consumption during alkaline extraction by adjusting solid-liquid ratios, and evaluating the impact of various isoelectric precipitants, including lactic acid and lactic acid bacteria (Lactobacillus plantarum and Lactobacillus lactis), on the functional and antioxidant properties of products across a wide range of pH values. It was here found that the process alternative with three 1:10 (w/v) extraction cycles and lactic acid bacteria as precipitant agent achieved high process productivity (0.36 kg protein product/kg pea flour) and low specific water consumption (94.9 kg water/kg protein product). No significant differences were observed in protein content and yield when compared to other flour-water ratios with higher water consumption or less eco-friendly precipitants. Products precipitated with lactic acid bacteria formed stable emulsions even at the isoelectric point, exhibited superior free radical scavenging activity, although solubility and water holding capacity were lower, and no differences were noted in oil holding capacity, foaming capacity, and foam stability.
