Obtención de un conservante natural a partir de la semilla de aguacate variedad Hass (Persea americana mill)

The objective of this project is to obtain a natural preservative from the Hass Persea americana miller avocado seed, in order to use it in the food industry. To carry out the main objective, it was essential to retrieve bibliographic information on the characteristics of preservatives in general, concepts about antioxidants, content of total polyphenols, antioxidant activity, enzymatic degradation tests, it was also necessary to make a characterization of the residue where determined properties of the raw material such as weight, length and diameter, bulk and bulk density, as well as moisture and ash content. This in order to bring the process to industrial scaling. In addition, tests were carried out on the preservative at 0.1%, 0.3% and 0.5% so that it could be applied in food evaluating pH, titratable acidity, and microbiological analysis. The extraction methods that were studied were ultrasound-assisted extraction and leaching, where, through a PUGH decision matrix, the relevant critical criteria for both the project were evaluated and thus the preservative was extracted at the best disposal with the methods found in the literature. Finally, the necessary variables were established to prepare an analysis of the financial viability of the project taking into account the evaluation criteria (IRR, IRT, Cash Flow, NPV and ROIC), in order to determine whether it is appropriate or not, Carry out this process to obtain the preservative from the food industry.
