Abstract:

Liquation, saccharification and purification of puffed corn meal were studied, and a new technology for producing sugar from puffed corn meal through liquation with medium-temperature α-amylase and gluten separation by sieving was developed. The results showed that using puffed corn meal as raw material instead of common corn meal, the liquation yield of starch is increased 7.82%, the saccharification time is reduced by 16.7%, and the final DE value of saccharification is up to 97.4. Furthermore, the production cost is reduced by 20% compared to traditional wet processing of starch sugar. Altogether, this new technology is energy-saving, water-saving and environment-friendly and has nice comprehensive benefit.
