Abstract

The purpose of this study was to investigate the effects of Lactobacillus rhamnosus GG (LGG) fermentation on the composition, structure, and functional properties of dietary fiber (DF) in bamboo shoot. Then, we added it to bread to evaluate the texture properties, digestive properties, and functionality of bread. After LGG fermentation, the DF was decomposed into pieces, which had stronger water-swelling capacity and nitrite adsorption capacity. The ability of producing short-chain fatty acids was significantly improved and the digestive resistance was remarkable enhanced as well. Except the bread hardness was increased, there was no significant difference in other texture properties when adding 3% FTDF-LGG to bread. It had good adsorption capacity of cholesterol and more than 25% reduced the release of reducing sugar. Overall, the technic of LGG fermentation had improved functional properties of DF in bamboo shoot, which could be applied to bread production for exerting its effects in the future.

Practical applications

Bamboo shoots are immature and tender stems of bamboo, rich in nutritional value, and rich in DF. Bamboo shoot DF has been proven to have a variety of biological activities, and is the main material for bamboo shoot to exert functional activities. In this study, bamboo shoot DF was modified by LGG fermentation, which showed stronger functional activity, and was successfully applied to bread. This study lays the foundation for the fermented modified bamboo shoot DF and its application in food.
