Silicone diffusion was used for the generation of passive modified atmosphere at low temperature to over come the deficiencies associated with LDPE based diffusion. The optimization of MAP variables (...
The quality of minced beef was improved. Combinations of modified atmosphere packaging (MAP) and vacuum packaging (VP) with lactic acid (LA), dihydroquercetin (DHQ) and linalool (LIN) mixes were used ...
In the past, food packaging was primarily used to support product sales and protect food from contamination or environmental e ects which would reduce the life of the food. According to the ...
The volatile organic compounds (VOCs) in the packing of chicken meat in a modified atmosphere was qualitatively and quantitatively evaluated. The total number of 72 samples of chicken hindquarters wer...
The effect of superficial treatment with taxifolin solution (1 g L-1) in combination with modified atmosphere packaging (80%O2/20%CO2) on the sensory quality and instrumental color characteristics of ...
This study evaluated the combined effect of Modified Atmosphere Packaging (MAP) and refrigeration (7±1°C) on shelf-life extension of ready-to-serve pizza. Quality assessment was based on sensory and b...
A mathematical model to predict oxygen, carbon dioxide, and water vapour exchanges in non-perforated and micro-perforated modified atmosphere packaging films has successfully been proposed. The transm...
为研究气调对蕨菜贮藏期间保鲜效果的影响,设置不同CO2和O2的体积分数,对蕨菜采后SOD活性、POD活性、呼吸强度、乙烯释放量、蕨菜干鲜重以及丙二醛、叶绿素、可溶性糖、VC含量进行了研究。结果表明:适宜的CO2和O2组合有利于采后蕨菜维持较高的SOD和POD活性,减少了MDA的积累,维持恰当的呼吸强度和乙烯释放速率,减少蕨菜干鲜重的损失,利于蕨菜采后叶绿素、可溶性糖、VC的保存。试验得出了最好的气...
气体置换装置是气调包装机的核心部件。以盒式气调包装机中2种典型气体置换装置结构为研究对象,建立了2种气体置换结构的物理模型和包装盒内气体流场分析数学模型,应用Fluent软件对包装盒内的气体流场进行三维数值模拟。建立了保证气体置换质量的包装盒内三维流场评价指标,分析了气体置换装置充、排气孔的结构布置与排列方式对气体置换性能的影响。结果表明,与传统结构相比,新设计结构在气体置换率、流场静压分布、气体...
The chemical components and quality stability of pre-cut Welsh onion wrapped in an unperforated or micro-perforated orientated polypropylene (OPP) film package were evaluated during storage at 10°C. T...
通过小袋法测定了不同材料薄膜分别在2、8、14、20℃下的薄膜透气系数,分析了温度对薄膜透气系数和透气系数比的影响。试验得出:随着温度的升高果蔬包装薄膜的透气系数增大,薄膜材料LDPE的透气系数比显著上升,但薄膜材料PVC的透气系数比在试验温度范围内呈现不同的变化趋势。薄膜透气系数与绝对温度之间满足Arrhenius方程,透气系数的自然对数值与绝对温度的倒数值之间呈显著的线性关系。 The gas...
Modified atmosphere conditions which would prolong the storage life of ‘Rong-Rien’ rambutan (Nephilium lappaceum) was investigated. Rambutans were packed in 0.04 mm low-density polyethylene (LDPE) bag...
The effect of modified atmosphere (80% oxygen +20% carbon dioxide) packaging, vacuum packaging and aerobic packaging on the microbial qualities viz., Total Viable Count (TVC) and anaerobic count, phys...
The synergistic effect between modified atmosphere and potassium permanganate based ethylene scrubber on ripening behaviour of unripe banana fruits was evaluated at 13±1°C followed by ethrel induced r...
Silicone diffusion was used for the generation of passive modified atmosphere at low temperature to over come the deficiencies associated with LDPE based diffusion. The optimization of MAP variables (...
