Effects of Different Extraction Method on Soluble Dietary Fibre Obtained from Apple Pomace
摘要
Abstract
The technology for extracted soluble dietary fibre from apple pomace was studied. Soluble dietary fibre was prepared by microwave and cellulase extraction. The optimal exatraction conditions of soluble dietary fibre by microwave through orthogonal tests, results showed that: the ratio of solid to liquid was 1:20, 1.5 min, fire was the intermediate fire(450W), pH 6.0. Under these conditions,the yield of soluble dietary fibre reached 13.6%. The water holding capacity and swelling capacity of dietary fibre product were 754.40% and 13 mL/g, respectively. The optimal exatraction conditions of soluble dietary fibre by cellulase were established through response surface analysi s (RSA). The results showed enzyme concentration 0.67%, pH 5.55, extraction 1.90 h at 45 ℃. Under the optimized conditions, the yield of soluble dietary fibre reached 17.50%. The water holding capacity and swelling capacity of dietary fibre product were 851. 25% and 15 mL/g, respectively.关键词
