Effect of potassium sorbate and modified atmosphere packaging on the shelf-life extension of seer fish (iScomberomorus commerson/i) steaks during iced storage.

摘要

A study to evaluate the influence of potassium sorbate combined with modified atmosphere packaging (MAP) at 2C on the shelf-life extension of seer fish (Scomberomorus commerson) steaks was made. The shelf life of 12 days in air pack was extended by 10 and 18 days in MAP and modified-atmosphere-packed seer fish pretreated with potassium sorbate, respectively. K value was not a suitable predictor of shelf life for seer fish. Potassium sorbate treatment showed further inhibition of total aerobic mesophilic count while sulfite reducing clostridial counts were 1 log cfu/g in all the packs after day 12 of storage. Potassium sorbate treated MAP samples showed higher sensory score on day 25 than those observed for MAP (PP<0.05) in shelf life was noticed due to MAP and treating samples with potassium sorbate.
