Characterisation of polyphenol oxidase and peroxidase and the role in browning of loquat fruit
Eriobotrya japonica PPO POD
2015/3/30
Polyphenol oxidase (PPO) and peroxidase (POD) were extracted from a new loquat fruit cultivar (Ninghaibai) and characterised using reliable spectrophotometric methods. In both cases, the optimum pH fo...
Dual Effects of Whey Protein Isolates on the Inhibition of Enzymatic Browning and Clarification of Apple Juice
apple polyphenoloxidase(PPO) whey proteins browning

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 ...
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...
