ALARCON RIVERA, Rafael; PEREZ CAMINO, María del Carmen  e  CHASQUIBOL SILVA, Nancy. Shelf life evaluation of Sacha Inchi oils (Plukenetia huayllabambana and Plukenetia volubilis) microencapsulated. Rev. Soc. Quím. Perú [online]. 2019, vol.85, n.3, pp.327-337. ISSN 1810-634X.

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 microcapsules obtained showed greater protection against oxidation, being the Hi- cap wall material that best protected the sacha inchi oils
