Production of the antioxidant ascorbyl palmitate by an innovative process of synthesis and purification

A
scorbyl palmitate, an antioxidant derived from ascorbic acid, represents a feasible alternative to petrochemical compounds such
as BHT, BHA and TBHQ, which are used in the food, pharmaceutical and cosmetic industries. The process developed in this
proposal considers an enzymatic synthesis of this compound using commercial lipase novozyme 435 in nonconventional medium
at 60°C, achieving 65% conversion. The main advantage is the absence of secondary compounds that occur when this antioxidant
is synthesized chemically, making the purification associated with the antioxidant to be simpler and cheaper, unlike the process
currently used in the industry, which corresponds to a chemical synthesis. The purification process contemplated in this proposal
comprises five-unit operations, considering a stage of recovery of the solvents used, to be a more environmental friendly process.
The ascorbyl palmitate obtained from this process meets the quality standards necessary for its use at industrial level, since it is
contemplated the use of solvents allowed by FAO in the manufacture of food additives, in addition to achieving a high purity, over
99%. Therefore, the process developed to obtain this antioxidant represents a highly competitive alternative at the industrial level.
