Abstract Vacuum drying of mango pulp at varying conditions of pulp thickness (2, 3, and 4 mm) and vacuum chamber plate temperature (65, 70, and 75°C) was carried out under 30–50 mm of mercury absolute pressure. A model based on moisture diffusivity was found to give close prediction to moisture content of the pulp at different times of drying with correlation coefficient varying between 0.98–0.99 for pure mango pulp and pulp with ingredients. Color change of reconstituted pulp made from mango powder was found to depend more on pulp thickness than plate temperature. For getting low color change vacuum drying should be carried at maximum pulp thickness of 2.6 mm and vacuum chamber plate temperature of 72.3°C. 相似文献

The pulp polyphenol composition of some Italian ancient apple cultivars, Dominici, Giachetta, Grigia di Torriana, Pom d'Aram, Ronzè, and Ros Borsetta, was studied in comparison with a Golden Delicious commercial variety, over a three-year period. Polyphenols were analyzed by liquid chromatography coupled with diode array and mass spectrometer detectors. The results showed that ancient varieties, such as Grigia di Torriana, Ros Borsetta, and Giachetta, constitute good sources of polyphenols, even without the peel. It was demonstrated that some representative apple phenolics, such as chlorogenic acid and phloridzin, were clearly affected by the harvesting year, whereas others, such as catechins and procyanidins, did not. 相似文献

Earlier work has shown that capturing the CO2 from flue gases in the recovery boiler at a market pulp mill can be a cost-effective way of reducing mill CO2 emissions. In this paper, it is investigated whether the same is valid for an integrated pulp and paper mill. Five configurations
are compared, supplying the extra energy needed by a biofuel boiler, an NGCC, a heat pump or by reducing the steam demand
at the mill in combination with a biofuel boiler or an NGCC. The configurations have been evaluated with energy market scenarios
and the avoidance cost has been calculated. The NGCC configurations have the lowest avoidance costs in all scenarios and they
also have the advantage of liberating biofuel for use in other parts of society.
