Optimization of Double Enzymatic Hydrolysis of Rice for Production of Infant Formula Rice Powder Using Response Surface Methodology

doi:10.7506/spkx1002-6630-201422012

Abstract

Abstract:

The enzymatic hydrolysis of rice slurry with α-amylase and β-amylase for use in infant formula rice powder
was optimized using a Box-Behnken design with response surface methodology. The optimal hydrolysis conditions
were established as follows: 0.04‰ (equivalent to 0.15 U/g) α-amylase, 0.26% (equivalent to 1 820 U/g) β-amylase, and
hydrolysis at 70.2 ℃, yielding a starch digestion index as high as 39.26%, which represented an over 10% increase over that
reported for commercial infant rice powder.

Key words: infant formula rice powder, α-amylase, β-amylase, mashing temperature, starch digestion index, response surface methodology
