Abstract

The Box-Behnken design combined with response surface methodology was used to optimize ultrasonic assisted extraction (UAE) of pectic substances from sugar beet pulp. The results indicated a highest extraction yield (16.3%) of pectic substances using UAE method using a frequency of 20 kHz and intensity of 99% for 10 min. In parallel, conventional acid extraction of pectic substances was also carried out. The highest yield could obtain by conventional method was 16% at a temperature of 90°C for 4 h. The crude extract of both procedure was then purified by centrifugation. The color attributes of UAE pectin compared to that of extracted by conventional method. Industrial relevance: Pressed sugar beet pulp, a residue of the sugar processing industry, is sold as animal feed at very low prices and readily available for revalorization, with few other commercial uses. Moreover, the drying process requires high energy and often presents an environmental problem. Therefore, numerous attempt

Conclusion

The optimized results showed that the highest extraction yield of pectic substances by ultrasonic-assisted extraction could arrive 16.26%, using ultrasound frequency of 20.21 kHz and ultrasound intensity of 99.9% for 10 min. The suitability of the model equation for predicting the optimum response value was treated using the selected optimal condition. Jafarzadeh-Moghaddam, Peighambardoust, Hesari and Azadmard-Damirchi 362 The predicted extraction yield of pectic substances was16.26%, which was almost consistent with the conventional extraction yield of pectic substances of 16.01%.
