PROCESS FOR PREPARING SWEET POTATO POWDER WITH INHIBITED BROWNING AND SWEET POTATO POWDER PREPARED THEREBY |
摘要 |
A method of manufacturing sweet potato powder with inhibited browning by soaking a peeled sweet potato in a sulfurous acid solution is provided to do not change an original quality characteristic of sweet potato while maintaining the original color and produce sweet potato powder with low residual sulfurous acid concentrations. A sweet potato is peeled in 950ppm sulfurous acid solution, soaked in the sulfurous acid solution for 3min, sliced into 1mm in thickness, soaked in 950ppm sulfurous acid solution for 3min, dried at 70deg.C until the moisture content reaches 3 to 5% and then ground to 80meshes. The treated sweet potato has a residual concentration of sulfurous acid of less than 10ppm.
