ABSTRACT

Problems with primary food production (food insecurity, malnutrition, and socioeconomic problems) persist throughout the world, especially in rural areas. Despite these problems, the available natural food resources are underutilized; residents are no longer interested in growing and consuming foods native to their region. In this regard, this study carries out the morphological and nutritional characterization of a native sunflower (Helianthus annuus) grown in the Sierra Gorda, Querétaro, Mexico, known as “Maíz de teja”, to implement a sustainable monoculture production system. The results were compared with some other sunflower varieties and other oilseeds grown and consumed in the country. This study determined that this native sunflower seed is a good source of linoleic acid (84.98%) and zinc (17.2 mg/100 g). It is an alternative protein source (18.6 g/100 g), comparable to foods of animal origin. It also provides a good amount of fiber (22.6 g/100 g) and bioactive compounds (total phenolic compounds (TPC) 3.434 ± 0.03 mg/g and total flavonoids (TFC) 0.67 ± 0.02 mg/g), and seed yield 341.13 kg/ha. This study demonstrated a valuable nutritional profile of this native seed and its potential for cultivation. Further research is needed to improve agricultural management to contribute to food security and improve the socioeconomic status of the community.
