Comparative Study of the Physicochemical, Functional, Thermal, and Rheological Properties of Pretreated Flours From Dioscorea alata and Dioscorea rotundata [PDF]

open access: yesFood Sci Nutr
Pretreatments help improve flour quality. The increase in solubility and dispersibility is greater in D. rotundata. D. alata flours are more resistant to shear than D. rotundata flours. All flours degrade after 200°C. D. alata flours are more elastic while D. rotundata flours are more viscous.

Enzymatic and Nonenzymatic Antioxidant Systems Affected by the Application of Hydrothermal Treatment and Calcium Chloride in Papaya Fruit. [PDF]

open access: yesInt J Food Sci
Papaya fruits have a high content of bioactive compounds that provide them high antioxidant capacity; however, these fruits undergo rapid deterioration processes once harvested, which implies a decrease in antioxidant activity. In order to reduce the oxidative stress that causes deterioration in the fruit, it is important to use technologies to ...

Packaging of Fresh Sliced Mushrooms with Essential Oils Vapours: A New Technology for Maintaining Quality and Extending Shelf Life

open access: yesFoods, 2021
The use of vapour of essential oils (EOs) through an innovative pilot-plant packaging device was studied to preserve the quality of sliced mushrooms during storage. A mix of EOs (eugenol, bergamot EO, and grapefruit EO) was vaporized (100 and 125 µL L−1)

Banana Polyphenoloxidase. Preparation and Properties [PDF]

open access: yesPlant Physiology, 1963
Griffiths (13) has presented evidence indicating that the browning reactions of banana fruit result from the enzymic oxidation of dopamine (3,4 dihydroxyphenylethyliamine) by polyphenoloxidase. Although dopamine does occur in various fruits and vegetables (23), it has not previously been implicated as an important substrate in browning reactions.

Inhibition of Palmito Polyphenoloxidase by Halide Salts [PDF]

open access: yesJournal of Enzyme Inhibition, 1998
The inhibitory properties of halide salts on palmito polyphenoloxidase (PPO) are described. Halide salts have the same inhibitory effect on the two forms of palmito PPO separated by hydrophobic chromatography. Fluoride and chloride ions showed a non-competitive, mixed type inhibition while bromide and iodide ions were found to be non-competitive ...
