Shelf Life Determination of Fresh Blueberries (Vaccinium corymbosum) Stored under Controlled Atmosphere and Ozone

Table 2

Mold counts (log CFU/g) and increase over 10 days (Δ) of highbush blueberries stored at 4°C or 12°C under controlled atmosphere storage conditions (CAS), ozone (O₃), or regular atmosphere (Air).

Treatment	4°C			12°C
	Day 0	Day 10	Δ	Day 0	Day 10	Δ
Air	<1.0	3.74	2.74	<1.0	3.75	2.75
CAS	2.85	4.95	2.10	2.24	2.60	0.20
O3	2.86	4.7	1.89	2.24	3.39	1.15

No growth at limit of detection.
Mold counts at day 7 used, because of no growth at day 10 due to high limit of detection.
