Abstract
Ultrasound-assisted extraction of pectin from Saba banana (Musa acuminata x balbisiana (BBB Group) "Saba") peels produced crude pectin that requires further purification. Two downstream processes (alcohol washing (AW) and acid demethylation (AD)) were compared. AW involved gelatinous precipitate washing with 85% alcohol and pressing to squeeze out liquids, while AD involved a sequential AW of the dried pectin with 60% acidified alcohol, and 60% and 95% alcohol solutions. Results showed that both methods produced low methoxyl pectins with similar color, yield, and moisture content, with no significant (p > 0.05) differences observed. AD, however, produced pectin with better quality in terms of ash content and anhydrouronic acid (AUA) content relative to the control. Fourier transform infrared spectra revealed that the samples contain -OH, C-H, COO-, COO, and C-O groups, but only AD has COO-R due to structural modification. Overall, AD has the potential to improve the quality of crude ultrasound-extracted pectin from Saba banana peels. Yet, pre-extraction processing methods are necessary to meet FAO color standards for pectin.
期刊介绍:
International Journal of Food Science is a peer-reviewed, Open Access journal that publishes research and review articles in all areas of food science. As a multidisciplinary journal, articles discussing all aspects of food science will be considered, including, but not limited to: enhancing shelf life, food deterioration, food engineering, food handling, food processing, food quality, food safety, microbiology, and nutritional research. The journal aims to provide a valuable resource for food scientists, food producers, food retailers, nutritionists, the public health sector, and relevant governmental and non-governmental agencies.
