The sacha inchi oils of ecotypes of Plukenetia huayllabambana and P. volubilis were microencapsulated to protect from environmental factors such as oxygen, light, moisture and the process conditions during the food processing. The study of the shelf life of the microencapsulated are very important for using them as a raw material in the development of functional foods. The objective of this work was to evaluate the shelf life of sacha inchi oils microencapsulated with different wall materials (Gum Arabic (GA), Hi-Cap, Maltodextrin (MD) and whey protein (WPI) ), alone or in mixtures; using the Rancimat method at temperatures of 70, 80, 90 and 100 ° C, respectively. The results of the shelf life extrapolated at 25°C of sacha inchi oils microencapsules were longer than sacha inchi oils without microencapsular, oxidative stability index and induction period (PI ), also confirmed that the m...

Los aceites de sacha inchi de los ecotipos Plukenetia huayllabambana y Plukenetia volubilis se microencapsularon para protegerlos de factores ambientales como el oxígeno, la luz, humedad y de las condiciones de los procesos durante la elaboración de los alimentos. El estudio de la vida útil del producto microencapsulado es muy importante a la hora de utilizarlo como materia prima en el desarrollo de alimentos funcionales. Por todo lo comentado anteriormente, el objetivo del trabajo fue evaluar la vida útil de los aceites de sacha inchi microencapsulados con diferentes materiales de pared (Goma Arábiga (GA), Hi-Cap, Maltodextrina (MD) y proteína de suero de leche (WPI)), solos o en mezclas; empleando el método Rancimat® a las temperaturas de 70, 80, 90 y 100°C.

Sacha inchi (Plukenetia huayllabambana L. and Plukenetia volubilis L.) edible oils were microencapsulated and the lipid fraction of the microparticles was characterized. Hi-cap®, Capsule®, Arabic gum, and the binary combination of Arabic gum + maltodextrin and the ternary combination of Arabic gum + maltodextrin + whey protein isolate, were used as coating materials for the encapsulation process using spray-drying. The surface and the total oils obtained from the microparticles were evaluated in terms of fatty acid composition, minor glyceride polar compounds, polymers, oxidized triglycerides, diglycerides, monoglycerides, and free fatty acids, along with their unsaponifiable components, sterols, and tocopherols. Differences between the original oils and the microencapsulated ones were determined. The most remarkable results included the presence of polymers when there were none in the...

The aim of this work was to obtain sacha inchi oil (SIO) microcapsules from two different species, 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 efficiency, 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 formulations 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 presented the highest oxidative stability and encapsulation efficiency compared to AG, AG:MD or AG:MD:WPC formulations.

Sacha inchi (Plukenetia huayllabambana) oil was co-microencapsulated with natural antioxidant extracts (NAE), such as camu-camu (Myrciaria dubia (HBK) Mc Vaugh) fruit, Añil variety Andean potato (Solanum tuberosum andigenum, and elderberry fruit (Sambucus peruviana). Gum Arabic and the ternary combination of gum Arabic (GA) + maltodextrin (MD) + whey protein isolate (WPI) at different formulations were used as coating materials for the encapsulation process using spray-drying. The moisture content, particle size distribution and morphology, total phenolic content, antioxidant activity, fatty acid and sterol composition, oxidative stability, and shelf-life were evaluated. Co-microcapsules of sacha inchi (P. huayllabambana) oil with camu camu skin extract (CCSE) at 200 ppm encapsulated with GA + MD + WPI had the highest total polyphenol content (4239.80 µg GAE/g powder), antioxidant acti...

This work tackles the study of the quality and authenticity of oils labeled and commercialized as extra virgin sacha inchi oil. Major and minor components as triglycerides, fatty acid methyl esters, tocopherols, sterols and hydrocarbons are determined as well as other physicochemical parameters (density, viscosity, acidity and peroxide value). The results showed that some of the commercialized oils do not fulfill the basic requirement established in the regulation such as the content of a-linolenic acid, higher than 44.7 or 55.0% in the cases of P. volubilis and P. huayllabambana, respectively. The calculated stigmasterol/campesterol ratio for genuine sacha inchi oils should be around 4, however not all commercial oils analyzed comply with this requirement. The presence of the flavons sesamin and sesamolin indicates the addition of compounds from sesame oils. Finally, some of the commerc...

This work deals with the characterization of the main glyceridic and unsaponifiable components of oils obtained from Sacha inchi (Plukenetia huayllabambana L.) seed ecotypes collected during two harvests in the Department of Amazonas in Peru. The seed-oil yield was 30.3–41.2%; standing out are the high percentages of the ¿3- and ¿6-fatty acids series whose ranges lie within those of the present Regulation for Sacha inchi oils. Triacylglycerols with even equivalent carbon number (ECN; 36–42) were the main components. Minor glyceridic polar compounds such as oxidized triglycerides, diglycerides, monoglycerides, and free fatty acids were determined by high-performance size exclusion chromatography. The low campesterol/stigmasterol ratio (1:6), unusual in the majority of vegetable oils, stands out. Regarding aliphatic hydrocarbons, these oils showed a particular profile for the saturat...

Este proyecto, iniciado en el 2015, se propone microencapsular aceites de sacha inchi (Plukenetia volubilis y P. huayllabambana) con antioxidantes naturales extraídos de algunos subproductos de la biodiversidad peruana, para ser empleados en la preparación de alimentos funcionales. De este modo, se eliminarán la inestabilidad y las alteraciones hidrolíticas de los aceites de sacha inchi, que representan un problema para su comercialización y almacenamiento. La formulación de alimentos funcionales con omega-3 y antioxidantes naturales contribuirá a mejorar la calidad de vida personas de 5 a 70 años de edad con oferta de jugos deshidratados y mayonesa light, y para bebés de 0 a 4 años con oferta de papilla. La producción de alimentos funcionales contribuirá a abrir nuevos mercados para el biocomercio de papa, yacón, tara, camu camu, kiwicha, quinua, cañihua y sauco, con lo cu...
