Reformulation of snacks offered to children and adolescents at school kiosks: is this strategy enough or just the tip of the iceberg?

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.

Experimental data acquisition and mathematical model for soluble protein extraction from Argentinian extruded expeller soybean meal.

Extruded expeller soybean meal is a byproduct of the soybean oil extraction, which is frequently used in Argentina by animal feed millers. In this work, the soluble protein extraction stage is studied as the first step of a challenge project in order to obtain a soy protein product from this byproduct. Extruded expeller meals from 4 different Argentinian processing plants were used to obtain 41 experimental data sets, using 1 to 3 consecutive extraction cycles operating at temperatures from 55 to 65 °C.
