An average of 0.21 kg spent gin botanicals (SGB) is generated for every 1 L of gin, making it the major by-product of gin distillation. The present circular economy dynamics and increased awareness on resource use presents an opportunity for valorisation of SGB. SGB was optimised for polyphenol extraction using a three-factor Box-Behnken Design in response surface methodology (RSM). This was used to both optimise and study how the extraction variables affected yields and values of polyphenol and antioxidant activity of SGB. The generated optimum conditions for polyphenol extraction from SGB were 50% (v/v) solvent concentration, 40 mL g−1 solvent: …
