MODIFIED SOYBEAN FIBRE AND HIGH-PERFORMANCE COMPOSITE GEL PREPARED USING SYNERGY OF SAME WITH GELLAN GUM

摘要

A modified soybean fibre and a high-performance composite gel prepared using synergy of same with gellan gum, relating to the technical field of food processing. Crushing dried bean dregs, sieving, and mixing with water, boiling the obtained mixed system at a pH of 10-12 and a temperature of 105-120℃, then stirring at a pH of 10-12 and a temperature of 40-60℃, centrifuging the obtained dispersion to collect the precipitate, re-dissolving the precipitate in water, adjusting the pH to neutral, centrifuging, and spray drying the obtained precipitate to obtain modified soybean fibre. Adding modified soybean fiber and gellan gum to water, shearing and stirring to mix uniformly, and thereby obtaining high-performance composite gel. The modified soybean fibre and gellan gum form the high-performance composite gel by means of the action of synergy, the gel strength, hardness, elasticity, and water retention of the composite gel being significantly improved.
