Caracterización fisicoquímica de oleogeles de aceite de aguacate (Persea americana) y sacha inchi (Plukenetia volubilis)

Due to the health consequences of an unhealthy diet with a high content of trans fats, food alternatives for health care have been developed, including natural foods with the minimum amount of carbohydrates and saturated fats. Therefore, the formulation of oleogeles free of trans fats was proposed from (w/o) emulsion using avocado and sacha inchi oil and different emulsifiers. A 3x3 factorial design was used in which the type of emulsifier: lecithin, glyceryl monostearate and the ratio of avocado and sacha inchi oil was varied. A product was obtained with greenish and yellow dyes, whose chromaticity b* is affected by the type of emulsifier, taking more yellow tones when the lecithin-glyceryl monostearate mixture is used. Formulations with a 70/30 ratio of oils using Lecithin as an emulsifier agent and formulation with an 80/20 oil ratio and using glyceryl monostearate showed the best results in terms of firmness in contrast to commercial margarines, meeting the physico-chemical requirements established in the current standards for oils and margarines such as: peroxide value (<10m-eq O2/kg fat), acidity (<0.8% oleic acid) and moisture content (≥ 16% w.b).
