Abstract

Parkia biglobosa is a non-wood forest product whose seeds contain an oil with interesting characteristics. Extracting this oil by pressing will produce a large quantity of oil cake. However, these cakes are not recovered and therefore constitute waste. This study therefore set out to transform this cake into a coffee substitute, using response surface methodology to optimise roasting conditions. The time and temperature varied from 10 to 20 minutes and from 190°C to 210°C respectively. Statistical analysis reveals that they have a significant influence on the response parameters (colour difference, polyphenol content and antioxidant activity) at the 95% confidence level. Colour difference, phenolic compound content and antioxidant activity increased from 32.499 to 54.608, from 53.406 mg/g to 79.036 mg/g and from 78.583% to 91.305% respectively. Roasting conditions (time and temperature) had an impact on phenolic compound content and antioxidant activity. This study revealed that antioxidant activity was correlated with polyphenol content, insofar as a decrease in polyphenol content with temperature led to a drop in antioxidant activity. So to produce the Parkia substitute with high nutritional potential, the response parameters must reach their maximum values. Under these experimental conditions, the optimum roasting parameters are 203°C for 12 minutes, resulting in a colour difference of 49.190, a polyphenol content of 73.949 mg/g and an antioxidant activity of 86.021%.
