Total antioxidant capacity of breastmilk from mothers following the 5th month postconception stored at various temperatures and durations (baseline to different storage temperatures and durations)

Mature milk (>5 months)	Mean TAC (SD) (µg/dL)
	Room temperature 37 °C	Refrigeration 48 hours 4 °C	Refrigeration 1 week 4 °C	Freezing 48 hours minus;8 °C	Freezing 1 week minus;8 °C
Mothers delivered
full-term	109.34 (11.4)	101.9 (12.03)	94.78 (11.1)	81.2 (4.76)	75.02 (5.2)
95% CI	101.2-117.5	93.3-110.5	87-102.7	77.8-84.6	71.3-78.7
Mothers delivered
preterm	106.36 (4.23)	100.03 (5.12)	93.31 (7.16)	82.72 (4.9)	73.55 (6.39)
95% CI	103.3-109.4	96.4-103.6	88.2-98.4	79.2-86.2	68.9-78.1

The paired and unpaired t-test analyses were applied. The TAC at all storage temperatures showed a difference from room temperature (baseline), which was highly significant (p<0.005).
