| 1 | 海水鱼的腐败因素及其相关代表性保鲜技术进展显示文摘海水鱼捕捞上岸后,因为环境的不适应性常常在短时间内死亡。由于其富含水分、营养丰富,海水鱼死亡后会迅速进入腐败过程,货架期短,因此海水鱼保鲜技术的研发十分重要。本文解析了不同海水鱼死后的酶自溶、微生物和脂质氧化导致的腐败,分析了海水鱼冷藏过程中各种内源性酶对海水鱼品质的影响,同时也归纳了不同种类海水鱼的特定腐败微生物及其产生的腐败代谢物。重点阐述了传统、新兴保鲜技术在食品工业的研究进展,比较了上述技术的保鲜原理和效果,同时也展望了海水鱼保鲜技术的未来发展。旨在为进一步开发及优化海水鱼保鲜技术应用于食品工业提供借鉴和参考。 | 谢晶 裴聚鑫 郁慧洁 孙锦涛 | 2022 | 上海海洋大学学报2022，31，5： | 1 |
| 2 | 基于神经网络的生鲜水产品货架期预测模型的构建及应用显示文摘为建立一种能够同时适用于多种新鲜水产品货架期的预测模型,采用反向传播(BP)神经网络模型、遗传算法(GA)优化的BP神经网络模型(GA-BP)、径向基函数(RBF)神经网络模型、极限学习机(ELM)神经网络模型和支持向量回归机(SVR)模型分别对金枪鱼、三文鱼、大菱鲆和鲷鱼的货架期进行预测,寻找最优的模型预测结果。首先通过试验获得4种水产品在0,4,10℃贮藏条件下的感官评分、菌落总数、挥发性盐基氮值、K值、pH值,构建训练样本和测试样本。经相关性分析,选择与水产品货架期相关性较高的感官评分、菌落总数、挥发性盐基氮值、K值作为模型的输入层单元,然后确定各模型的网络拓扑结构以及参数,进行模型的训练,最后使用训练好的5种模型对测试样本的货架期进行预测。结果表明:5种预测模型的预测精度排序为:SVR模型>RBF神经网络模型>GA-BP神经网络模型>ELM神经网络模型>BP神经网络模型,其中BP神经网络模型的预测精度最差,均方误差(MSE)为9.5127×10^(-4),平均绝对误差(MAE)为0.0197,平均绝对百分比误差(MAPE)为0.0825,R^(2)为0.9766;SVR模型的预测精度最优,预测误差均在12%以内,MSE为2.2971×10^(-4),MAE为0.0128,MAPE为0.0631,R^(2)为0.9944,能够很好地同时预测4种水产品在不同储藏温度下的货架期。本研究为水产品的品质控制提供一定的理论基础。 | 崔方超 毛智超 李婷婷 励建荣 | 2023 | 中国食品学报2023，23，11： | 0 |
| 3 | Editorial:Improving fish from catch to the consumer:Post harvest handling,processing,packaging,transportation and storage显示文摘Aquaculture is the fastest growing food producing sector,accounting for almost 50%of the animal protein consumed globally,with the expectation that it will rise to 65%by 2030,due to the increasing emphasis on fish products as important components of a healthy diet.However,EU production is stagnating with approximately 60–65%of European demand for fish products being imported(EUMOFA,2021).The reason for this is complex and the sector faces a number of challenges. | Theofania Tsironi | 2023 | Aquaculture and Fisheries2023，8，4： | 0 |
| 4 | Physicochemical properties of silver carp(Hypophthalmichthys molitrix)mince sausages as influenced by washing and frozen storage显示文摘Frozen storage of emulsion-type sausages may be one approach to avoid or reduce the use of sodium nitrite,which is associated with health risks.Silver carp(Hypophthalmichthys molitrix)mince(M_(0))was washed for 1(M_(1))or 3(M_(3))times and the impact of washing on the properties frozen storage(−18℃)during 4 months were determined and results were compared to those of conventional silver carp sausages(Mt).Lipid oxidation,as evidenced by changes in thiobarbituric acid reactive substances and FFAs,took place during storage in the order of M_(0)>M_(1)=M_(3)=Mt with M_(0)being highly oxidized(P≤0.05).Total volatile base nitrogen formed during storage and the ranking for the quality loss was as follows M_(0)>M_(1)>M_(3)=Mt.Washing(M_(1)=M_(3))led to less hardness(P≤0.05).Mt had better redness,while M_(1)and M_(3)led to higher expressible moisture,water release and lightness(P≤0.05).Results indicated the lower sensory and consumer-liking properties of frozen M_(1)and M_(3)sausages.Therefore,washing and frozen storage influenced silver carp mince sausages. | Kaveh Rahmanifarah Joe M.Regenstein Mehdi Nikoo | 2023 | Aquaculture and Fisheries2023，8，4： | 0 |
