The Potency of Avocado Seeds (”Persea Americana” Mill.) as a Source of Antioxidant Tea

Abstract

The processing of avocado into avocado juice will produce organic waste, namely avocado skin, and seeds. This potential of organic waste from avocado seeds can be exploited by turning them into tea products. This study employed avocado seed as a source of antioxidants which was made into processed products, namely tea. This research was intended to discover the influence of temperature with avocado seeds on antioxidants as well as the quality of resulting tea products and to determine the best conditions for the drying process of avocado seed tea. This investigation was arranged at the Integrated Lab of Politeknik Indonesia Venezuela and the Laboratory of Banda Aceh Industrial Research and Standardization Center. The experimentation adopted a factorial completely randomized design pattern composed of 2 (two) parameters. The first parameter was avocado seed drying temperature comprising 3 (three) degrees, they were S1 (50°C), S2 (60°C), and S3 (70°C). The second parameter represented the drying time of avocado seeds which comprised 3 (three) degrees, they were L1 (2 hours), L2 (2.5 hours), and L3 (3 hours). Analysis carried out in the research was water, ash value, phenolic content, antioxidant, and sensory (colour, taste, and flavour). From the research, it was shown that the drying temperature was influenced by the moisture content, ash content, and antioxidant activity of avocado seed tea, while the drying time and the treatments of those parameters made an impact on total phenol. The best quality avocado seed tea was obtained from a drying temperature of 50°C along with a length of drying of 2 hours.

Application of Avocado Seed as Textile Natural Dye

“…Among the efforts to reduce the impact of waste, avocado seeds are used as natural dyes on fabrics. Anwar et al, [18] reported the utilization of avocado seeds as antioxidant tea. Another application of avocado seed was studied by Novelina et al, [19] as a mixture of modified cassava flour in cookies production.…”

Pretreatment of Used Cooking Oil Using Avocado Seed Adsorbent for Biodiesel Production Preparation

“…The use of avocado seeds as an adsorbent has been widely carried out. The results of the research of Munawarah et al (2022) andPutra et al (2022) showed that avocado seed activated charcoal has the potential as an adsorbent of Cd 2+ and Pb 2+ ions. The adsorption potential of avocado seed activated charcoal on Cd 2+ and Pb 2+ ions is optimum at concentrations of 0.38 ppm and 4.83 ppm, respectively, with adsorption efficiency of 97.11% and 97.92%, respectively (Munawarah et al, 2022) and 99.34% for Cd 2+ ions and 98.86% for Pb 2+ ions (Rahayu, 2014).…”

Characterization of avocado seed activated charcoal showed that activation using 5% H2SO4 activator had good characteristics with a water content of 3.68%, ash content of 0.84%, iodine adsorption 385.22 mg/g, and a surface area of 19.62 m 2 /g.…”
