黄金梨气调贮藏中CO2对果实组织褐变及品质的影响（Effects of Different CO2 Volumefraction on Fruit Browning and Quality of ‘Whangkeumbae’during Controlled Atmosphere Storage）
黄金梨 保鲜 气调贮藏 CO2体积分数
2010/12/29
研究了O2体积分数为3%，CO2体积分数分别为0、0.5%、1.0%、2.0%、3.0%，温度为0℃，相对湿度为80%～85%条件下的气调贮藏对黄金梨贮藏后货架期间果实品质、采后生理以及组织褐变情况的影响。结果表明，与CK相比，5个气调处理对果实硬度下降均有一定的抑制效果，但体积分数为0的CO2气调处理能明显抑制果实呼吸强度，抑制果实的PG活性，贮藏180d时，未发生果皮和果肉褐变（包括CK），...
Effect of Temperature and pH on Nonenzymic Browning in Minced Dried Pepper During Storage
Minced dried pepper Nonenzymic browning Temperature pH
2009/10/15
The effect of temperature and pH was investigated on the nonenzymic browning reactions in minced dried paprika. The browning pigments formation was both pH and temperature dependent. Increasing pH in ...
Kinetic Modelling of the Maillard Browning Reaction in Pekmez (Grape Molasses)
Maillard reaction Temperature pH Concentration
2009/10/14
The effects of pH, temperature and total solube solids on the Maillard reactions which occurred during the storage of Pekmez were determined using accelerated storage test. The reaction was followed m...
Comparison of Enzymatic Browning of Japanese Pear and Apple
apple (Malus x domestica) Japanese pear (Pyrus pyrifolia) enzymatic browning
2009/7/8
When Japanese pear and apple are cut, the section of Japanese pear does not turn brown as readily as apple, although both fruits belong to the same family. Here, the enzymatic browning of the two frui...
The Effect of Lipid Oxidation in Frozen Pulverized Niboshi (Boiled and Dried Sardine) on Color Browning and Formation of Free Amino Acid
lipid oxidation dried fish browning free amino acid
2009/7/7
The relationship between lipid oxidation in pulverized niboshi which occurred during freezing and further oxidation, free amino acid loss, and browning which took place after the sample had been thawe...
Correlations between Barley Constituents and the Browning Reaction in Heat-Treated Barley Pastes
hull-less barley browning reaction proanthocyanidin
2009/6/18
The browning reaction in barley products after boiling or steaming is undesirable in human food. We estimated the degree of browning reaction—the browning index (BI)—by the difference in the Hunter’s ...
Effect of Combination of Heating and Pressurization on Browning Reaction of Glucose-Glycine Solution and White Sauce
pressure high hydrostatic pressure browning
2009/6/18
The effect of the combination of heating and pressurization on Maillard reaction was investigated using a model solution of glucose and glycine, and a white sauce. The apparent browning rates were cal...
The effectiveness of pineapple stem protease (bromelain) in enzymatic browning inhibition was evaluated on apple juice and compared with that of L-cysteine and ascorbic acid at 25±1°C. The relative ef...
