Packaging Venison for Extended Chilled Storage: Comparison of Vacuum and Modified Atmosphere Packaging Containing 100% Carbon Dioxide

Thirty red deer (Cervus elaphus) stags were slaughtered at three deer slaughter premises (plants A, B, and C) to determine the effects of initial microbial flora on the quality of chilled venison loins stored using three packaging methods: vacuum packaging (VP), modified atmosphere packaging using an ultra-high barrier outer barrier film (CO2-UHB), and modified atmosphere packaging using a dual aluminized polyethylene outer barrier film (CO2-MPET), all of which were stored for 6, 12, and 18 weeks at −1 ± 3°C. Carcasses slaughtered in plant B had higher aerobic plate counts than those killed at either plants A or C. Location of slaughter had little effect on loin quality except for drip loss, pH and anaerobic and lactic acid bacteria counts. Oxygen levels increased in the modified atmosphere packages (P<0.05) during storage from 12 to 18 weeks (CO2-UHB, 1%; CO2-MPET, 0.05%). Loins packaged in CO2 -UHB exhibited less acceptable surface color than meat packaged in CO2 -MPET or VP. Aroma, flavor, texture, and acceptability scores decreased (P<0.05) when loins were stored over 12 weeks regardless of packaging method. pH values of loins packaged in modified atmosphere packs were lower (P<0.05) than those in VP. The regression relationship between percent drip loss and pH was given by % drip = 39.1–6.49 [Standard error (SE) 1.52] pH. Acceptable display color of steaks cut from the loins, regardless of treatment, decreased as loins were stored from 6 to 18 weeks. These results suggest that vacuum packaged venison loins resulted in meat of acceptable quality after 12 and 18 weeks of chilled storage, and that modified atmosphere packaging contributed no additional benefit.

Effects of active modified atmosphere packaging (initial O2/CO2: 5/5; 30/5; and 80/0) and passive packaging [initial O2/CO2: 20.8/0 (air)] on the antioxidant capacity and sensory quality of fresh-cut ‘Yaoshan’ pear stored at 4 °C for 12 days were investigated. Samples stored in high O2 (30% and 80%) packages had higher phenolics and anthocyanin contents compared with those in passive and low O2 packages. After 12 days of storage, phenolics and anthocyanin contents of 80% O2 samples were 2.5 and 12 times, respectively, higher than those in the passive package and 3 and 2 times higher than those in low O2 package. High O2 modified atmosphere packaging was effective in keeping free radical scavenging capacity as measured by the DPPH assay. The sensory evaluation indicated that surface color of cut fruits were stable for at least 12 days in the high O2 modified atmosphere packaging. The results suggested that high O2 modified atmosphere packaging could be used to inhibit browning and prolong the shelf life of fresh-cut ‘Yaoshan’ pears in spite of more than 50% loss in vitamin C content.

Pampus Argenteus

The effects of modified atmosphere packaging (MAP: 80%CO2/20%O2) and chitosan (CS: 10.0g/L) on the shelf-life of pomfret (Pampus argenteus) fillets during chilled storage were studied. Quality assessment was based on biochemical (total viable counts (TVC), total volatile base nitrogen (TVB-N), tri-methylamine (TMA-N), K-value, pH value) and sensory analysis indices determination. The results showed that MAP and CS could keep the sensory quality of Pampus argenteus, delay its deteriorating speeds and slow down the increase of K-value effectively. Compared with the control samples, the shelf-life of pomfret samples in MAP and CS stored at 4±1°C were 10, 12d respectively.

Plate Counts

The objective of this research was to observe the effect of chlorine dioxide (ClO2) combined with modified atmosphere packaging on the quality of fresh chicken breasts under refrigerated storage for 15 days. Each chicken breast was inoculated with a 4-log CFU/ml culture of Salmonella Typhimurium (nalidixic acid–resistant strain) and placed into a barrier foam tray. Fast- or slow-release ClO2 sachets were placed next to the chicken in each package. A control set of packages that did not contain a ClO2 sachet was also included in the study. Packages were flushed with either 100% N2 or 75% N2–25% CO2 and stored at 3°C. Microbial analysis, CIE L.a.b. color, and sensory (appearance and aroma) were performed every 3 days for 15 days. Total plate counts for chicken increased steadily after 6 to 9 days of storage regardless of package atmosphere or ClO2 treatment. However, those treated with ClO2 sachets had 1 to 1.5 log CFU per chicken breast lower total plate counts compared with those without ClO2 sachets. After 15 days, samples treated with ClO2 (fast- and slow-release sachets) had significantly lower Salmonella Typhimurium (nalidixic acid–resistant strain) populations (approximately 1 log) compared with chicken that did not contain ClO2 sachets. The ClO2 adversely affected the color of the chicken in areas close to the sachet. No off-odor was detected by the sensory panelists.

Meat Samples

The aim of this study was to evaluate the effect of the packaging system type on the physical characteristics and microbial changes in ostrich meat during refrigerated storage. The applied packaging systems were vacuum packaging (VP) and modified atmosphere packaging (MAP) using two combinations of gases: MAP1 (40% O2/40% CO2/20% N2) and MAP2 (60% O2/30% CO2/10% N2). Eight meat samples were obtained in three replicates for all parameters, except for pH, for which six replicates were obtained from the M. ilifibularis (IF) muscle, and were stored in a refrigerator at 2 °C and analyzed at 0, 4, 8, 12 and 16 days for the effect of packaging methods on physical meat quality. The initial pH (5.99) decreased at the end of the storage time for MAP1 to 5.81, whereas VP was stable from day 0 to 12 and increased up to 6.08 on day 16. Regarding meat color, the L* value increased during storage for MAP1 and MAP2 from 36.99 to 40.75 and 41.60, respectively, whereas it declined for VP to 34.22. The same tendencies were reported for redness (a*) and yellowness (b*). Drip loss was the lowest in MAP1 and highest in VP. The lowest total viable bacteria counts were identified in VP, as compared to MAP1 and MAP2.

AbstractFresh-cut lettuce is a very well-known salad for today's routines because it obliges minimal preparation to minimize the loss of health beneficial vitamins, minerals, antioxidants and other phytochemicals. It is a prodigious challenge to serve its consumers fresh. Quality of freshly processed lettuce under high CO2 modified atmosphere packaging (MAP) has been investigated as a realistic alternative technique for its preservation. Storage under high CO2 atmospheric treatments exhibited a significant impact in microbial development, electrolyte leakage, volatile metabolites and sensory quality of fresh-cut iceberg lettuce. This storage condition (MAP 1: 5 kPa O2 and 20 kPa CO2 balanced by N2 at 7 °C for 6 days) inhibited the growth of mesophilic bacteria and yeasts; delayed the enzymatic browning (cut-edges and intact surface) of fresh-cut iceberg lettuce and overall visual quality was also in acceptance limit. The development of off-odors was perceived in high CO2 MAP as a consequence of volatiles (ethanol and acetaldehyde) accumulation which was persisted at an inexcusable level during 6 days of storage periods.
