    Influencia del proceso de secado convectivo en el contenido de antocianinas, compuestos fenólicos totales, capacidad antimicrobiana y antioxidante en frutillas (Fragaria annanasa var. San Andrea)

    La frutilla (Fragaria ananassa) posee compuestos bioactivos de interés nutricional y elevada actividad antioxidante, que pueden conferir importantes beneficios a la salud humana. Sin embargo, son productos altamente perecederos. El objetivo de este trabajo fue deshidratar frutillas por secado convectivo, para extender su vida útil. Se ensayaron tres temperaturas del aire de secado: 60º, 70º y 80 ºC y una velocidad de 0,7 m/s. Para caracterizar las harinas obtenidas, se midió el color, la capacidad antimicrobiana y antioxidante, el contenido de antocianinas y de compuestos fenólicos totales (CPT), en extractos hidroalcohólicos generados por agitación. La harina de frutillas obtenida conservó o incrementó el contenido de CPT y la capacidad antioxidante, particularmente cuando la materia prima se deshidrató a 70 ºC. El contenido de antocianinas disminuyó y el color también fue modificado. Se evidenció la potencialidad de las harinas de frutillas para su aprovechamiento como ingrediente en la formulación de alimentos, por sus aportes de compuestos bioactivos.

    Purpose: This study aimed to formulate multiple nutritionally improved snacks intended for school-aged children according to international nutritional goals: Vanilla cookies (VC), Bay biscuits (BB), Cheese crackers (CC), and Tomato muffins (TM). Design/methodology/approach: The reformulation targets implied incorporating alternative flours and milk powder, and reducing the sugar and sodium contents, with respect to the usually consumed control products. These products were subjected to proximate composition, colour, and sensory profile analyses. Their overall acceptability was assessed by school-aged children whose nutritional status was also evaluated. Findings: Significant increments in relevant nutrients were observed in the composition of snacks: fibre (p=0.01 for VC, p<0.01 for BB and CC), proteins (p<0.01 for all snacks), and calcium (p<0.01 for all snacks). Average sodium reductions of 1.5 % and 3.7 % were achieved for CC and TM. During formulation, added sugar was reduced by 15.5 % and 23.5 % for VC and BB. All snacks were found to be acceptable in terms of appearance, texture, flavour, and overall acceptability by the participants, and VC, BB, and CC were ready for their effective implementation as part of school meals. Originality/value: Comprehensive policies have become necessary to combat malnutrition, mainly overweight and obesity. The incorporation of nutritionally improved snacks in school environments is one of several strategies for promoting healthier lifestyles among children, including educational programs, workshops, and food assistance.
