“…Some processing factors affecting palm kernel oil yield recovery in a hot-water extraction system have been detailed by Obetta and Onwualu (2007). Gandh et al (2005) reported the possibility of using some alternative solvents like n-propanol, isopropyl alcohol, ethanol and n-hexane in place of of n-hexane for the extraction of peanut oil. However, small amount of oil was also wasted in the residue.…”

An experiment was conducted to evaluate and standardize the protocol for enhancing recovery of oil and quality from cold pressed wild apricot kernels by using various enzymes. Wild apricot kernels were ground into powder in a grinder. Different lots of 3 kg powdered kernel were prepared and treated with different concentrations of enzyme solutions viz. Pectazyme (Pectinase), Mashzyme (Cellulase) and Pectazyme + Mashzyme. Kernel powder mixed with enzyme solutions were kept for 2 h at 50(±2)°C temperature for enzymatic treatment before its use for oil extraction through oil expeller. Results indicate that use of enzymes resulted in enhancement of oil recovery by 9.00-14.22 %. Maximum oil recovery was observed at 0.3-0.4 % enzyme concentration for both the enzymes individually, as well as in combination. All the three enzymatic treatments resulted in increasing oil yield. However, with 0.3 % (Pectazyme + Mashzyme) combination, maximum oil recovery of 47.33 % could be observed against were 33.11 % in control. The oil content left (wasted) in the cake and residue were reduced from 11.67 and 11.60 % to 7.31 and 2.72 % respectively, thus showing a high increase in efficiency of oil recovery from wild apricot kernels. Quality characteristics indicate that the oil quality was not adversely affected by enzymatic treatment. It was concluded treatment of powdered wild apricot kernels with 0.3 % (Pectazyme + Mashzyme) combination was highly effective in increasing oil recovery by 14.22 % without adversely affecting the quality and thus may be commercially used by the industry for reducing wastage of highly precious oil in the cake.

“…The dehulled seeds were dried in a vacuum oven at 318K (Johnson and Lusas, 1983;Becker, 1978). It is listed as a hazardous air pollutant by the US Clean Air Act since it can react with other pollutants to produce ozone and photochemical oxidants (Wan et al, 1995a;Hanmoungjai et al, 2000) and its use in oilseed extraction plants can adversely affect workers' central nervous system (Becker, 1978;Johnson and Lusas, 1983;Lusas et al, 1991;Gandhi et al, 2003). The control of its emission levels in extraction plants requires the installation of additional control equipment at additional costs (Conkerton, et al, 1995).…”

“…Almeida et al (2017), em um estudo sobre a extração do óleo de Moringa utilizando diferentes solventes, entre eles acetona e hexano, observaram que em todos os tempos analisados, o hexano extraiu maior quantidade de óleo O mesmo não foi observado neste trabalho para as extrações de óleo de polpa de abacate. Gandhi et al (2003), buscaram diversos solventes para extração de óleo de soja, desta forma, utilizaram os solventes puros n-hexano, n-heptano, n-propanol, isopropanol e etanol, além da aplicação de sistemas de solventes aquosos (90:10 n-propanol) e azeótropos como, por exemplo, n-hexano + isopropanol (78+22), em períodos de extração crescentes até 10 h. Desta maneira, concluíram, ao se comparar com o n-hexano, n-heptano, n-propanol, isopropanol e etanol foram efetivos na extração de forma igual, o que é notado neste experimento visto que na proporção 1:10 a 55°C todos os solventes foram efetivos na extração do óleo da polpa do abacate.…”

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)
