Preparation of water-soluble dietary fiber from bamboo shoots by fungi fermentation and its supplementation in biscuits
Expanding the utilization of bamboo shoots is extremely meaningful in China because of the high output every year. In this study, the bamboo shoot powder was used as a substrate to produce water-soluble dietary fiber (WSDF) by fermentation with a screened fungi strain Trichoderma dorotheae MLG23, and the prepared WSDF was utilized in the production of biscuits. The bamboo shoots and their residues, WSDF, and biscuits were analyzed on Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), inductively coupled plasma mass spectrometry (ICP-MS), and texture analyzer. The results showed that the fungi exhibited a strong ability to express extracellular cellulase. The enzymatic activities of filter paper activity (FPA), cellobiohydrolase (CBH), and ꞵ-glucosidase (BG) secreted by the strain showed the highest at 50 °C, reaching 0.13, 0.19, and 1.20 U/mL, respectively, and the highest enzymatic activity of endoglucanase (EG) with 0.37 U/mL was obtained at 60 °C. The highest WSDF yield of 45.97 wt% was obtained under the fermentation conditions of bamboo shoot loading 30 g/L, strain inoculum 1010 CFU/L, and fermentation time 4 d at 30 °C. The cellulose and hemicellulose in bamboo shoots were partially utilized by the fungi to produce WSDF. The main metal elements in WSDF were Mg, K, Ca, and Zn. The hardness, cohesion, chewiness, resilience, and adhesion of the biscuits showed a gradual decrease with the increase of WSDF addition in the range from 0 to 10 g per 100 g of low gluten flour. The incorporation of WSDF disrupted the network structure of the gluten, leading to the reduction of some textural properties and the change of microstructure. These results showed a potential utilization of bamboo shoot in production of WSDF and functional biscuits.
期刊介绍:
Official Journal of the European Federation of Chemical Engineering:
Part C
FBP aims to be the principal international journal for publication of high quality, original papers in the branches of engineering and science dedicated to the safe processing of biological products. It is the only journal to exploit the synergy between biotechnology, bioprocessing and food engineering.
Papers showing how research results can be used in engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in equipment or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of food and bioproducts processing.
The journal has a strong emphasis on the interface between engineering and food or bioproducts. Papers that are not likely to be published are those:
• Primarily concerned with food formulation
• That use experimental design techniques to obtain response surfaces but gain little insight from them
• That are empirical and ignore established mechanistic models, e.g., empirical drying curves
• That are primarily concerned about sensory evaluation and colour
• Concern the extraction, encapsulation and/or antioxidant activity of a specific biological material without providing insight that could be applied to a similar but different material,
• Containing only chemical analyses of biological materials.
