Optimization of Different Variable for Eco-friendly Extraction of Betalains and Phytochemicals from Beetroot Pomace

Optimization of Different Variable for Eco-friendly Extraction of Betalains and Phytochemicals... Beetroot pomace is majorly considered as waste from beetroot processing industry though it contains higher amount of betalains and other phytochemicals which can be utilized in medicinal and food applications. In the present study, Fourier Transform Infrared Spectroscopy analysis of pomace also confirmed the presence of the betalian and phenolics by identifying the major functional groups. Therefore, an attempt has been made to optimize an eco-friendly method for extraction of betalains and phytochemicals from beetroot pomace by considering different experimental variables such as solid-to-liquid ratio (1:15–1:45), temperature (30–70 °C), time (2.50–12.50 min) and pH (1.50–5.50) using response surface methodology. Beetroot pomace was dried, grinded and subjected for extraction of betacyanin, betaxanthin, phenolics and antioxidants using different combinations of experimental variables. A prediction model was optimized and validated to get the optimum conditions. Solid-to-liquid ratio (1:15), temperature (50.04 °C), time (10 min.) and pH (2.50) was the optimized process conditions for the extraction of betalains and other phytochemicals achieved with the best fit of desirability i.e. 0.889. So, it is concluded that beetroot pomace can be successfully utilized cost effectively rather than simply thoroughly it in the open conditions or converting it in to compost. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Waste and Biomass Valorization Springer Journals

Abstract

Beetroot pomace is majorly considered as waste from beetroot processing industry though it contains higher amount of betalains and other phytochemicals which can be utilized in medicinal and food applications. In the present study, Fourier Transform Infrared Spectroscopy analysis of pomace also confirmed the presence of the betalian and phenolics by identifying the major functional groups. Therefore, an attempt has been made to optimize an eco-friendly method for extraction of betalains and phytochemicals from beetroot pomace by considering different experimental variables such as solid-to-liquid ratio (1:15–1:45), temperature (30–70 °C), time (2.50–12.50 min) and pH (1.50–5.50) using response surface methodology. Beetroot pomace was dried, grinded and subjected for extraction of betacyanin, betaxanthin, phenolics and antioxidants using different combinations of experimental variables. A prediction model was optimized and validated to get the optimum conditions. Solid-to-liquid ratio (1:15), temperature (50.04 °C), time (10 min.) and pH (2.50) was the optimized process conditions for the extraction of betalains and other phytochemicals achieved with the best fit of desirability i.e. 0.889. So, it is concluded that beetroot pomace can be successfully utilized cost effectively rather than simply thoroughly it in the open conditions or converting it in to compost.
