EXTRAÇÕES DE ÓLEO DA POLPA DE ABACATE (Persea americana MILL) UTILIZANDO DIFERENTES SOLVENTES

Abstract

RESUMO: O abacate (Persea americana Mill) é um fruto originado do continente ABSTRACT: Avocado (Persea americana Mill) is a fruit originated from the American continent, widely produced in Brazilian territory. Its fleshy pulp provides the extraction of a high quality oil containing several bioactive compounds. In this work, the viability of avocado oil extraction was evaluated using different extraction conditions. The avocado pulp was dried in an oven, and then milled to obtain a bran. Extractions were performed with 3 g of the sample and varying amounts of solvent (ethanol, hexane, isopropanol and acetone) to obtain different solid: solvent ratios (1: 5, 1: 7.5 and 1:10). The system was incubated in Shaker at constant temperature (35 °C, 45 °C and 55 °C)

Pumpkin (Cucurbita maxima) by‐products: Obtaining seed oil enriched with active compounds from the peel by ultrasonic‐assisted extraction

“…To reduce environmental impacts, such as the emission of greenhouse gases, ethanol can be used as an oil extraction solvent, since it is renewable, formed by biotechnological processes, it is a nontoxic solvent with low flammability (Bessa et al, 2017), and because it has similar capacity to n ‐hexane for oil extraction (Baümler, Carŕin, & Carelli, ; Escorsim et al, ; Oliveira & Menezes, ; Rodrigues, Mello, Garcia, & Silva, ).…”

Reaproveitamento de resíduos gerados pelas espécies Persea americana e Theobroma grandiflorum: Uma alternativa para sustentabilidade ambiental

“…O abacate (Persea americana Mill) é um fruto originado do continente americano, amplamente produzido no território brasileiro (Oliveira et al, 2017). É cultivado em todas as regiões tropicais e subtropicais do mundo, particularmente no México, Indonésia, Estados Unidos, Brasil, Chile, Colômbia, República Dominicana, Peru e Etiópia, a produção brasileira é distribuída nas regiões Sudeste, Nordeste e Sul, e o estado de São Paulo é o maior produtor seguido pelos estados do Paraná e Espírito Santo ( Paixão et al, 2016).…”
