Temperature and Exposure Time Impact on the Extraction of Opuntia ficus-indica and Opuntia dillenii Cladodes on % Yield as a Response: Screening using Design Expert Software

Abstract

Objectives: The main aim of the present work is to screen the effect of temperature and exposure time (ET) on the extraction of Opuntia ficus-indica and Opuntia dillenii cladodes. Material and Methods: The literature revealed that few attempts were made on the cladodes and other parts of the plants for extracting constituents from them. However, no attempts were made on screening to find out the impact of dependent variables on the independent response. Design of the experiment using quality by design software, namely, Design Expert was used to reveal the impact of the dependent variable on the response. Results: O. ficus-indica and O. dillenii were poised, authenticated, and were hauled out with water and the effect of dependent variables (temperature and ET) on the response (% yield) was assessed. The equation coded from this study for the % yield was generated as +54.30+0.4061A–0.6432B+0.1500AB+0.8375A2+0.3875B2. Conclusion: The study revealed that 65°C is the optimum temperature and the extraction and ET are directly proportional to extracting the contents from the cladodes.
