“…The list of materials that have been tested in such studies is long (and still increasing). Some examples include pine bark [282,283,302,304,305], almond shells [292,307], banana peels [284,293], sawdust [153,285,300], coconut fibers [285], rice bran [271,287], rice husk [271,287], moringa pods [271], hazelnut shells [299,300], wood residues [286], cork wastes [85,153,154,289,295,303,306] and chickpea husk [288]. In addition, assays have also been conducted with some of these materials after submitting them to more or less complex treatments (usually thermal), e.g.…”

“…This probably depends to a great extent on their polarity; the hydrophobicity of citral (log P = 2.7) was higher than that of butyl acetate (log P = 1.8); that is, a higher log P means a more hydrophobic compound. Within homologous series of aroma compounds, the higher the hydrophobicity of the aroma compound's substituent, the greater the possibility of establishing weak interactions with the contact surface . Such an unequal adsorption phenomenon may cause a change in the original ratios between volatiles and, consequently, a change in the character of the aroma.…”

Scalping of aroma compounds from food simulants into polyethylene terephthalate laminated steel

BACKGROUND Aroma scalping is a very common problem and can affect the sensory quality of packaged food. To study the aroma scalping characteristics of polyethylene terephthalate laminated steel (PET‐LS), the sorption kinetics of six common aroma compounds (2‐pentanone, 2‐heptanone, hexanal, citral, butyl acetate, isopentyl acetate) in foods were assessed for drawn–redrawn cans made with PET‐LS. RESULTS Storage temperature and initial concentration were proved as important factors to affect compound sorption and diffusion for flavors. The correlation between logarithm of equilibrium absorption ln M∞ and reciprocal of absolute temperature 1/T showed good linear relationship (R2 = 0.9380–0.9998) at 4 °C, 20 °C and 50 °C, and the M∞ obtained by the experiment was very close to the predicted value at 37 °C. At low initial concentration (below 500 µL L−1), the absorption capacity and initial concentration showed a slow linear growth trend, whereas there was a rapid change at high initial concentration. The values of diffusion coefficient D were on the order of 10−11–10−12 m2 day−1, which were lower than reported for other polymer materials (linear low‐density polyethylene, polybutylene succinate, polylactic acid). CONCLUSION The equilibrium absorption amount of each flavor component was dependent on the temperature under the same concentration (500 µL L−1). The Fickian diffusion model was used for fitting the experimental kinetics values satisfactorily (R2 = 0.9158–0.9885). © 2019 Society of Chemical Industry

The present study deals with slow pyrolysis of sesame oil cake in an isothermally operated 50 mm diameter and 640 mm long semibatch pyrolyser in the temperature range of 673−1173 K. Under isothermal condition, a lumped parameter model has been used to determine the kinetic parameters for degradation of solid reactant and formation of volatile and char. The iso-conversional kinetics applicable for DAEM (distributed activation energy model) processes have also been determined for pyrolysis of sesame oil cake under nonisothermal conditions based on the thermogravimetric analyses data at different heating rates. The activation energies at different conversion almost follow a Gaussian distribution. On the basis of presently determined lumped kinetic parameters and the literature data for secondary pyrolysis kinetics, a mathematical model has been developed. The model can predict the time histories of unreacted solid, char, CO, H 2 , CO 2 , CH 4 and condensable pyro-oil. Simulated predictions have been compared with the experimental results satisfactorily.
