Determination of the physicochemical properties and fatty acid profile of the oil of the seed obtained from the processing of passion fruit (Passiflora edulis)juice

Abstract

In general, the industrialization of fruits, like any food industry, involves the generation of a considerable amount of waste that can be used in various ways, such as animal feed, fertilizers, obtaining biogas, in the extraction of oils, pectins, flavonoids, among others. However, in most cases, the fate of waste generated from fruit processing is not managed properly, generating a negative impact on the environment. The objective of the present investigation was to evaluate the effect of the extraction method on the physicochemical properties and fatty acid profile of the seed oil obtained from the processing of passion fruit juice (Passiflora edulis), for which a factorial design 23 was applied. independent variables were type of raw material (fresh seeds and maracuya industrial waste seed) and extraction method (pressing and solvent) and dependent variables redimiento, acidity, peroxide index and oleic and linoleic acid content. It is concluded The cold pressing method allows to obtain higher oil yield for seeds of industrial waste of passion fruit. The extraction method affects the content of oleic and linoleic acids in the oil of the seeds of industrial waste of passion fruit, if you want an oil with a higher content of oleic acid the method to use is by cold pressing and if you want a higher acid content Linoleic is by solvent extraction. The extraction method affects the physicochemical properties of the oil (peroxide index and% acidity), these being higher when the method is used by solvent extraction.
