  • Processing temperature and reduction of GABA particle size during granulation are significant factors that can affect the chemical stability of GABA.
  • Small particle size of HPC can cause higher degradation due to higher surface area in contact with GABA particles.
  • Processing parameters (screw speed and feed rate) should be optimized to achieve the balance between improving compaction properties but still maintaining chemical stability of GABA.
