Development of Efficient Polydextrose Production Process and Device Improvement
Polydextrose is produced by mixing edible glucose,sorbitol and citric acid in a certain proportion and then melting and condensing under high-temperature and vacuum conditions,and there are some shortcomings in the production,such as unstable polymerization temperature control,high polymerization viscosity and fluctuation with the process,poor heat transfer of materials leading to caramelization reaction,and slow polymerization speed leading to deep color of products.In this paper,taking the reducing sugar mass fraction and chroma of the synthesized product as reference indexes,the influence of heating mode,temperature control method,reaction temperature,reaction time,polymerization viscosity,reaction negative pressure and other process conditions on the synthesis effect of polydextrose was studied,the polydextrose synthesis process was optimized,and the optimized method to improve the existing device was put forward,so as to make the product polymerization process under effective control,and thus produce polydextrose in an efficient manner.
