| Abstract: | Objective]The research aimed to discuss the technology conditions of producing mannose-oligosaccharides by hydrolyzing konjak gum using neutral β-mannanase under middle-test conditions.Method] Under the conditions of single factor test,hydrolytic conditions of konjak gum for producing mannose-oligosaccharides were studied with neutral β-mannanase from Bacillus subtilis.Result]When konjak gum was hydrolyzed by enzyme method for producing mannose-oligosaccharides,the optimized enzymatic hydrolysis conditions were as follows:pH of 6.0,konjak gum concentration of 150 g/L,β-mannanase dosage of 200 IU/g konjak gum,enzymatic hydrolytic temperature of 50 ℃ and hydrolytic time of 3 h.Conclusion]The research could greatly enhance the additive value of konjak gum. |
| Keywords: | β-mannanase mannose-oligosaccharides konjak gum |
