Lycopene green ultrasound-assisted extraction using edible oil accompany with response surface methodology (RSM) optimization performance: Application in tomato processing wastes

Effect of tomato (Solanum lycopersicum L.) lycopene-rich extract on the kinetics of rancidity and shelf-life of linseed (Linum usitatissimum L.) oil

“…Kehili, Choura, Zammel, Allouche, and Sayadi (2018) studied the effect of oleoresin tomato peel on the oxidative stability of olive and sunflower oil for 19 weeks at 50 °C, using BHT as a control (200 mg/kg) and found that they had a protective effect on primary oxidation, strongly correlated to the presence of lycopene. The sunflower oil used to extract lycopene from tomato wastes showed a better oxidative stability than the pure oil during storage at 60 °C for 21 days (Rahimi & Mikani, 2019). Zhang, Yang, Zu, Chen, Wang, and Liu ( 2010) observed the protective effects of carnosic acid addition on sunflower oil during 21 days at 60 °C, and reported significant lower FFA, PV and p-AV than those of the sunflower oil control as well as of oil enriched (200 mg/kg) with synthetic antioxidants (BHT and BHA).…”

Tomato as Potential Source of Natural Additives for Meat Industry. A Review

“…The ideal conditions were the application of 70 W/m 2 during 10 min and the use of 1:5 solid/solvent ratio. According with the results, the use of Oil-UAE at optimal conditions extracted higher amounts of lycopene (91.5 mg/100 g) in 10 min than the conventional extraction, using hexane (63.7 mg/100 g) or hexane/acetone/methanol (2:1:1) mixture (74.9 mg/100 g) after 1 h [77]. However, it should be noted that the use of this technique does not allow the removal of the solvent (oil), so, if the lycopene will be used to reformulate some food must be incorporated together with the oil.…”

“…Finally, although the use of different assisted extraction technologies and the optimization of multiple parameters that affect carotenoids extraction presented clear advantages as low extraction times or the use of less solvent amounts, among other, all researchers commented above use toxic solvents to the lycopene extraction. Thus, to overcome this problem, a recent study proposed the utilization of edible oils (renewable and non-toxic solvent) as substitute of toxic organic solvent to recover lycopene from tomato by-product [77]. The green extraction proposed by these authors is the combination of edible oil (sunflower oil) with UAE.…”

“…The green extraction proposed by these authors is the combination of edible oil (sunflower oil) with UAE. The use of oil is a promising substitute to the conventional solvents due to the high solubility of lycopene in oil and acts as barrier against oxygen, delaying the oxidative degradation rate of carotenoid extract [77]. Additionally, the benefits reported above of the use of UAE resulted in improve of lycopene yields.…”

A brief overview on valorization of industrial tomato by-products using the biorefinery cascade approach

“…Solvent extraction has usually low yields due to the complex structure of the cell walls where the lycopene is trapped; moreover, degradation of the carotenoids can occur due to high temperature and long extraction time, reducing the lycopene extract quality. To overcome this problem, several techniques have been proposed in the literature, including: sonication-assisted extraction (Yilmaz et al, 2017, Rahimi andMikani, 2019), microwave-assisted extraction (Ho et al, 2015), enzyme-assisted extraction (Ranveer, 2013;Catalkaya and Kahveci, 2019) and Naviglio extraction (Naviglio et al, 2008).…”
