In khaoklongngok gamma-aminobutyric acid (GABA) is the substance in which this type of acids play an important role towards the central nervous system. Help prevent disease or Alzheimer disease lose memory helps stress and have the ability to reduce blood pressure. This project aims to study and compare the effects of pH and temperature of the aqueous solution to create GABA in khaoklongngok, from which the experimental rice to soak in the solution with pH 5, 6, 7, 8 and 9, and then find the quantity of GABA in aqueous solution extracted from khaoklongngok by measuring the t absorb light.่ 630 NM It was found that the chilled with khaoklongngok solution is 60 hours of precious pH6 quantity most GABA, but it gradually decreased as more and more time, when the experimental study on the effect of temperature on rice by soaking in a solution of 10 to 20, pH6, 25, and 30° c for a period of 60 hours. It was found that a series of experiments in which the temperature is 30 degrees Celsius in the GABA increases possible.
