Caracterización de las mezclas de aceite de semillas de maracuyá y pepa de aguacate como material cambio de fase

Abstract

Passion fruit seeds such as avocado seed are considered organic waste of industries, giving it a utility as oil, and finding an applicability makes it sustainable and attractive to the national market since they are native products. Based on the above, this research seeks to characterize a new phase change materials from organic waste to give it an application and take advantage of its usefulness. The present research work in a first stage will carry out the obtaining of the oils of the passion fruit seeds and avocado seed from which they will be mixed in the established proportions and the oils will be characterized by means of Differential Scanning Calorimetry, Infrared Spectrometry and Thermogravimetry to determine its properties and catalog it as a phase change material. The results showed that the candidates for phase change materials for their high enthalpy are the 100% avocado oil samples with fusion enthalpy of 73.96 J/g, melting temperature of -23.69 0Cand 25% passion fruit-75% avocado oil with melting enthalpy of 40.01J/g, melting temperature of -39.050C that can be used as thermal storage at low temperature. The technological contribution of this research work will focus on that from renewable, cheap raw material that is considered a waste or waste of the food industry to be able to take advantage of this waste to give it a new use.
