RESUMEN
Bioaccessibility analysis and antioxidant activity along in vitro digestion and a consumer-oriented sensory analysis were conducted in three potential functional foods based on Ca(II)-alginate beads containing bioactive compounds extracted from beet stems. Ca(II)-alginate beads per se, and two selected products (cookies and turkish delights supplemented with the beads) were prepared. Regarding the beads, among the attributes rated by consumers, visual appreciation predominates, being color in the just-as-right (JAR) category and in the like preference. Instead, both flavor and sweet taste were attributes highly penalized and should be improved in beads to be accepted as food per se. A higher percentage of customers preferred cookies and turkish delights instead of only beads, considering global satisfaction. Regarding in vitro digestion, there was a significant content of phenolic compounds in the products with beads, showing a bioaccessibility greater than 80% (for cookies) and 26% (for turkish delights). Also, the antioxidant capacity measured by ABTS ranged between 50 and 109% for cookies and turkish delights, being lower when measured by FRAP (between 20 and 30%, respectively). Thus, including the beads with beet stem extract in both products leads to a significant increase in the content of phenolic compounds and in the antioxidant capacity compared to their counterparts, protecting the compound during oral and gastric phases. These results allow the generation of improved Ca(II)-alginate systems with promising functional properties for the development of ingredients and functional foods.
RESUMEN
La triquinelosis es una enfermedad parasitaria ocasionada por el nematodo Trichinella spiralis. Actualmente el tratamiento utilizado para la triquinelosis es la administración de albendazol o mebendazol. Estos medicamentos son efectivos contra el parásito, solo si se administran por periodos prolongados; sin embargo existe el inconveniente de que pueden causar efectos adversos en el hospedero. El objetivo de este trabajo fue evaluar el efecto terapéutico del medicamento OXAL® (albendazol/quinfamida) contra la infección por T. spiralis en modelo murino, durante la fase intestinal de la infección (1 y 7 días) por un periodo de 3 días. Los resultados obtenidos mostraron que la administración de OXAL® durante 3 días, tuvo eficacia terapéutica durante la fase intestinal, ya que no se obtuvo carga parasitaria en el grupo con 1 día de infección, y la obtenida en el grupo con 7 días de infección tuvo una disminución significativa respecto al control, p < 0.05
Trichinellosis is a parasitic disease caused by the nematode Trichinella spiralis. Currently the treatment for Trichinellosis includes the administration of albendazole or mebendazole. These drugs are effective against the parasite, only if administered for prolonged periods; however there is a drawback that can cause adverse effects on the host. The aim of this study was to evaluate the therapeutic efficacy OXAL® (albendazole/quinfamide) against infection by T. spiralis in mice during the intestinal phase of the infection (1, and 7 days) for a period of 3 days. The results showed that administration of OXAL® for 3 days, had effective therapy for intestinal phase, since there was no parasitic load in the group with 1 day of infection, and the obtained in the group with 7 days of infection showed a significant decrease with regard to control, p <0.05
