Dataset for the publication entitled "Pulsed ultrasound-assisted extraction of lycopene and β-carotene from industrial grated tomato by-products"

The aim of this research was to study the effect of temperature, time, and amplitude as operating variables (using Response Surface Methodology -RSM-on ethanolic pulsed ultrasound-assisted extraction (UAE) of carotenoids from industrial grated tomato by-products, due to be a great source of lycopene. The major strength of the study is the use of industrial tomato by-products. A Central Composite Design was used for RSM optimization. Fixed variables were particle size (<56 μm), solid:liquid ratio (2:25), and duty cycle (30:30). Carotenoids were quantified as equivalents of β-carotene (for lutein and ∑β-carotene), and lycopene (∑Lycopene and ∑Carotenoids).
