Physicochemical characterization and oxidative stability of microencapsulated edible sacha inchi seed oil by spray drying
Get PDFThe aim of this work was to obtain sacha inchi oil (SIO) microcapsules from two different spe-cies, Plukenetia volubilis L. (SIVO) and Plukenetia huayllabambana L. (SIHO), using different biopolymers as wall materials and spray drying technology. The physicochemical characteristics such as encapsulation effi-ciency, particle size, morphology and oxidative stability were analyzed in order to select the best formulation that could potentially be used as an ingredient in the development of functional food. Bulk SIO and four formu-lations were tested for each oil ecotype, using different encapsulating agents: maltodextrin (MD), Arabic gum (AG), whey protein concentrate (WPC) and modified starch HI-CAP®-100 (H). Microcapsules made of H pre-sented the highest oxidative stability and encapsulation efficiency compared to AG, AG:MD or AG:MD:WPC formulations
A Study on the Biodiversity of Pigmented Andean Potatoes: Nutritional Profile and Phenolic Composition
Get PDFThe characterization of six varieties of native Andean potatoes with a wide biodiversity in tuber shape, flesh, and skin color was performed, through the determination of their proximate composition, mineral content, and phenolic profile. Minerals concentration revealed significant genotypic variation. Potassium was the most abundant element in all varieties, ranging from 7272.9 to 13,059.9 µg/g and from 12,418 to 17,388.6 µg/g dried weight for the flesh and skin samples, respectively. Iron content was relevant, ranging from 20.5 to 39.9 µg/g and from 112.2 to 288.8 µg/g dried weight in flesh and skin samples, respectively. Phenolic compounds were consistently higher in the skin than in the flesh. The total content varied greatly from 19.5 to 2015.3 µg/g and from 1592.3 to 14807.3 µg/g dried weight for flesh and skin tissues, respectively. 5-caffeoylquinic acid was 74% of the total phenolic acids. Different pattern of anthocyanins was found, depending on the color of the variety; the red genotypes contained predominantly pelargonidin derivatives, while the purple samples had petunidin as a major anthocyanidin. This study increases the knowledge of the composition of the local Andean varieties (which are only scarcely studied so far), helping to enhance these genotypes and the conservation of biodiversity

riesgos de deficiencia nutricional y de
enfermedades crónicas no transmisibles
en personas en situación de mayor
vulnerabilidad. Para ello se ofrecerán
prácticas saludables de consumo de
alimentos, así como una oferta sostenida
y competitiva de alimentos funcionales de
origen nacional. El proyecto desarrollará
alimentos funcionales mediante la
incorporación de microcápsulas de aceite
de sacha inchi, rico en omega 3, y de
antioxidantes de la biodiversidad peruana. De
esta forma, se cierra un ciclo más del estudio
liderado por la misma investigadora y se abre
el camino a la transferencia tecnológica y a la
producción a gran escala.El objetivo del proyecto es prevenir los
