Abstract
Description
This study aimed at producing isomaltooligosaccharides in juice blends using orange juice and malt extract and assessing their acceptability. Different blend formulations were prepared and fermented, varying the concentration of orange juice, sucrose and malt extract. Dextransucrase from Weissella cibaria 10 M was used to enzymatically synthesize α(1–6) linked glucan-oligosaccharides by transglycosylation reactions, with maltose as acceptor carbohydrate and sucrose as donor. The optimal yield of oligosaccharides was after 24 h, producing 19.4 g/L of oligosaccharides (degree of polymerization 3) from 36 g/L maltose and 19 g/L sucrose. All the blend proved to be good alternatives for synthesizing isomalto-oligosaccharides with different degrees of polymerization. Sensory analysis showed good average acceptability compared to natural orange juice, achieving scores of around 6 on a 9-point hedonic scale. In a comprehensive analysis, juice blends containing orange juice and malt extract with Weissella cibaria to produce oligosaccharides exhibited good sensory indicators as an innovative prebiotic beverage. A prebiotic oligosaccharide beverage can be produced by enzymatic synthesis of oligosaccharides with different degrees of polymerization.
