Table 2. Moisture content, pH, soluble solids and color property of flour and galangal powder

Sample	Weak flour	Galangal powder	Significance
Moisture content (%)	12.66±0.701)	12.88±0.39	NS2)
pH	6.24±0.09	5.13±0.14	***3)
Soluble solid (°Brix)	0.90±0.00	1.97±0.06	***
Color property
Lightness (L*)	92.74±0.01	65.55±0.10	***
Redness (a*)	0.28±0.00	6.91±0.01	***
Yellowness (b*)	8.48±0.01	24.46±0.02	***

All values are mean±SD (n=3). Values in the same row with asterisks (^*) are significantly different (p<0.05), as determined by a two-sample t-test.
NS, not significant.
Significant at *p<0.05, *p<0.01.
