Study on compound black fungus powder and evaluation of in vitro hypolipidemic capacity

BAO Yihong;GAO Peidong;School of Forestry, Northeast Forestry University;  
Black fungus lipid-lowering powder was prepared by using black fungus as main raw material and oats, coix seed, maltodextrin, xylitol and xanthan as the auxiliary material. The effects of boiling time, drying temperature, particle size on the effect of black fungus powder's in vitro hypolipidemic capacity were discussed. The best making powder process and the best ratio of black fungus, oats and coix seed were determined by the single factor and orthogonal experiments. On the basis of that, by using dispersibility index, sedimentation rate, dispersion time, and sense evaluation as detection index, the single factor and response surface methodololgy(RSM) design were used to decide the optimum additive of the maltodextrin,xylitol, xanthan gum and the best preparation technology of black fungus powder reduction and product formula were obtained. The results showed that the best making black fungus powder process, black fungus were soaked, washed and boiled 20 min, dried in the oven at 80 ℃, crushed and seived by 80 mesh sieve.The best ratio was black fungus 47.6%, oats 17.3%, coix seed 21.6%, maltodextrin 7.4%, xylitol 5.6% and xanthan gum 0.5%. The product had good water-mixing property, sensory quality and high nourishment. In vitro digestion experiment, its bile acid salt combining ability was 1.18 μmol · 100 mg-1and cholesterol absorption ability was 23.2 mg·g-1, showing that it had good function in vitro hypolipidemic capacity.
