摘要

Abstract Combining different preservative treatments for improving quality and safety of fishery products increasingly receives global research attention. Consistent with this pursuit, the current research was undertaken to determine the effects of different ozonized slurry-ice treatments and superchilling (?￠????1???°C) storage on microbial spoilage of European anchovy ( Eugraulis encrasicolus ) and sardine ( Sardina pilchardus ), which are two commercially important pelagic fish species. After the catch (within <5 hr) and at defined scheduled storage times, ozone has been discharged once on sardine (herein referred to as ?￠????One-T?￠????) and repeatedly/sequentially on European anchovy (herein referred to as ?￠????Seq-T?￠????). Microbiological analyses enumerated total viable count (TVC), Bacillus spp., Enterobacteriaceae , Lactobacillus spp., Moraxella spp., Shewanella spp., Listeria monocytogenes and Pseudomonas spp. Independent of potential antimicrobial effects of ozone during superchilling storage, no Listeria spp., Shewanella spp., Moraxella spp., and Bacillus spp. were found in all processed samples. While Enterobacteriaceae and Lactobacillus spp. were detected at below 1 log cfu/g, both TVC and Pseudomonas spp. proliferated at different rates throughout superchilling storage. The repeated ozone-treated (?￠????Seq-T?￠????) showed lower TVC and Pseudomonas spp. values compared with one-time treated (?￠????One-T?￠????) slurry-iced and control samples. Thus, combined slurry-ice and superchilling storage at Seq-T produced improved antimicrobial activity over One-T application. Largely, ozonized slurry-ice outcomes/results appear promising thanks to superchilling storage.

Seq-T ￠-???）。微生物学分析列举了总存活数（TVC），芽孢杆菌属，肠杆菌科，乳杆菌属，莫拉氏菌属，希瓦氏菌属，单核细胞增生李斯特菌和假单胞菌属。在过冷存储期间，与臭氧的潜在抗菌作用无关，没有李斯特菌属，希瓦氏菌属，莫拉氏菌属和芽孢杆菌属。在所有处理过的样品中都被发现。而肠杆菌科和乳酸杆菌属。在TVC和假单胞菌属物种中检测到的低于1 log cfu / g。在整个超冷存储中以不同的速率扩散。重复的臭氧处理（ΔSeq-TΔT）显示较低的TVC和假单胞菌属。值与一次性处理过的（结冰）和对照样品（一次）相比较。因此，与One-T应用相比，Seq-T的冰浆和超冷储藏相结合产生了更高的抗菌活性。很大程度上，由于过冷存储，臭氧化浆冰的结果/结果似乎很有希望。
