Financial and Biotechnological Assessment of New Oil Extraction Technology

Abstract

Grape seed oil is recognized for its high quality bioactive compounds, however, these are sensitive to increased temperatures during manufacture. Technical and economical potential of the pretreatment in combination with the mixture of hydrolyzing enzymes have been analyzed. It was confirmed that the shockwave pretreatment significantly enhances the subsequent enzymatic hydrolysis, which subsequently better liberates the vacuoles rich in oil (without exceeding the temperature limitation). The assessment of oil yields achieved together with the holistic cost analysis indicates that this technology has significant technical potential. Admittedly, it still faces difficulties linked with increased cost of production.

Supercritical CO2 extraction of grape seeds oil: scale‐up and economic analysis

“…Such value is comparable to the results previously reported in the literature for industrial production of grape seeds oil: US$ 7.85 per kg‐oil in 2010 (Fiori, ) and US$ 12 per kg‐oil in 2012 (Prado et al ., ). The cost of shockwave pretreated cold pressed grape seeds oil is estimated at US$ 14.8–21.9 per L (Marousek et al ., ).…”

Characteristics and evolution of bioethanol from Manila Tamarind (Pithecellobium dulce) leaf through fermentation

“…Similar to this, the maximum oil output from grape seeds was obtained using a combination of pressure shock wave induction and enzyme hydrolysis procedures. Individual underwater shake pretreatment and enzyme hydrolysis, as reported by Marouek et al in 2015[Maroušek et al, 2015, enhanced oil extraction by 10% and 16%, respectively. These efforts are expected to contribute to the development of energy self-sustainability strategies in developing countries, particularly those based on bioethanol.…”

Real-time online monitoring technology for sweeping frequency ultrasound (SFU) assisted extraction of amur grape (Vitis amurensis) seed oil

“…Traditional oil extraction methods are mainly organic solvent extraction [9] , physical expression [10] and enzyme treatment [11] . However, the organic solvent extraction speed is slow, and the solvent has a certain degree of toxicity, and it's not safe [12] ; physical expression of oil production cycle is longer than other methods of oil extraction, and its production process is relatively cumbersome and low production efficiency; the enzyme treatment of fats and oils process is simple with low energy consumption, which can reduce the loss of nutrients, but the cost of enzyme preparations is higher [13] , the enzyme dissolution time is longer, and the extraction process about the formation of the mixed emulsion of oil, water and proteins need complex equipment to be able to be separated. Moreover, AGS hardness is high, the extraction rate is low but with long time, so it is necessary to develop a green efficient extraction of AGS oil.…”
