Metabolic engineering focuses on improving cellular activities as an applied science by the use of recombinant DNA technology. Metabolic engineering has been advanced as an effective tool for improving industrial fermentation processes. As cell factories, engineered microbes constructed by designing metabolic pathways can convert carbon sources such as sugars into value-added chemicals and food materials. Rational metabolic engineering is related to the engineering of enzymes and regulatory proteins based on a rational analysis of the regulation of a target metabolic network. Biotransformation using microbial fermentation has provided robust and safe manufacturing processes for food ingredients. Human milk contains essential nutrients and functional ingredients for promoting infant health. Human Milk Oligosaccharides (HMOs) are a part of these functional ingredients. Sugar alcohols can be acquired when aldehyde or ketone in sugars is reduced to the hydroxyl group and widely found in fruits and vegetables.
