Pectinmethylesterase affects the flow behavior of orange pulp

Journal of Food Science, 2021
Abstract In the orange juice industry, pulp (ruptured juice sacs) is separated from the juice after extraction and pasteurized separately before blending back with juice or sold for other food applications.

Pectinmethylesterase inactivation by bubbling with N2

Biotechnology Techniques, 1998
The half-life of pectinmethylesterase decreased from 8.5 h in an aqueous solution to 3.5 h when 100 mL/N2 min−1 was bubbled through it at 50°C. Inactivation strongly depended on the pH and the ionic strength and was enhanced at a pH close to the pI of the enzyme.

Separation of Thermostable Pectinmethylesterase from Marsh Grapefruit Pulp

Journal of Agricultural and Food Chemistry, 2000
A rapid, ion-exchange method that isolates thermostable pectinmethylesterase (TS-PME) from Marsh grapefruit pulp is presented. TS-PME was selectively extracted with 1 M NaCl and equilibrated at low pH (3.1 +/- 0.04). After dilution to a final concentration of 50 mM acetate buffer, pH 5.5, and 0.1, 0.25, or 0.5 M NaCl, the extract was applied to an ion ...

Inactivation of Heat-Resistant Pectinmethylesterase from Orange by Manothermosonication

Journal of Agricultural and Food Chemistry, 1999
Pectinmethylesterase of navel oranges shows two fractions greatly differing in thermostability. The most thermostable fraction accounts for approximately 10% of total activity. The thermal inactivation of this fraction follows first-order kinetics both in 5 mM, pH 3.5, citrate buffer and in orange juice at the same pH, showing a z value of 5.1 degrees ...

Pectin from Passion Fruit Fiber and Its Modification by Pectinmethylesterase

Preventive Nutrition and Food Science, 2010
Passion fruit fiber pectin gels represent a new alternative pectin source with potential for food and non-food applications on a commercial scale. Pectic polysaccharides were extracted from passion fruit (Passiflora edulis) fiber using citric acid as a clean catalyst and autoclaved for 20 to 60 min at $121^{circ}C$.
