Table 4. Changes in acid value and peroxide value of carotenoid-enriched oil affected by oxidation treatment

Oil sample1)	Δ Acid value2) (mg/g)		Δ Peroxide value (meq/kg)
	Non-treated	Oxidation treated		Non-treated	Oxidation treated
Control	0.07±0.062)	0.10±0.10		1.20±1.74	9.93±5.01
CESO	0.03±0.06	0.03±0.05		0.30±0.26	7.83±2.25

Control, non-treated soybean oil; CESO, carotenoid-enriched soybean oil prepared from persimmon peels by ultrasonic extraction (62°C, 32 min, persimmon peel to oil ratio of 1:3.1).
Δ Acid or peroxide value, (acid or peroxide value after oxidation treatment) – (initial acid or peroxide value before oxidation treatment).
Values represent mean±SD (n=3).
