Estudio piloto de preferencia y aceptabilidad de recetas con camote biofortificado: un estudio transversal a nivel comunitario

Abstract

Background: Vitamin A deficiency persists as public health problem in Panamanian rural communities. Objective: To determine acceptability and preference of four recipes using biofortified sweet potatoes by Panamanian women in rural non-indigenous and indigenous communities. Materials and Methods: A descriptive and cross-sectional pilot study with 50 women from rural non-indigenous and indigenous communities of El Cope (Cocle Province) and Chichica (Comarca Ngabe Bugle), in Panama. Sensory acceptability and preference tests were applied using hedonic scale to evaluate four local recipes (sweet potato pesada, sweet potato drink, sweet potato tamale, and roasted sweet potato). Sociodemographic data, diversity of diet and frequency of vitamin A food sources were collected. Additionally, vitamin A composition analysis were used to evaluate the content in the biofortified sweet potato. Results: A total of 50 women, 62 % in Chichica, 52 % in 34-49 years range. Significant difference was observed in diet diversity for roots/tubers and vegetables groups in Chichica 81 % y 48 %, respectively) and El Cope (42 % y 11 %, respectively) (proportional test (prtest), p<0.05); as well as for orange colored fruits, meats and milk/ dairy groups in Chichica (55 %, 42 % y 58 %, respectively) and El Cope (84 %, 74 % y 79 %, respectively) (prtest, p<0.05). High acceptability for all recipes, pesada (94 %), sweet potato drink (98 %), tamale (100 %), and roasted sweet potato (84 %). Preference is high for sweet potato tamale in both communities as a savory recipe; and sweet potato pesada in El Cope (74 %) and sweet potato drink in Chichica (61 %) as sweet recipes (prtest, p=0.0163). Vitamin A content in the biofortified sweet potato is 1000μg/100g. Conclusion: The four recipes are accepted. Preference for tamale in both communities; preference for pesada in El Cope and sweet potato drink in Chichica.
