Changes in cell wall constituents and mechanical properties during post-harvest hardening of trifoliate yam Dioscorea dumetorum (Kunth) pax tubers
In an attempt to investigate the changes leading to the rapid post-harvest hardening of the white cultivars of Dioscorea dumetorum tubers, alterations in the plant cell wall constituents and mechanical properties of the tubers were monitored. A 4 × 2…
Application of response surface methodology for studying the influence of soaking, blanching and sodium hexametaphosphate salt concentration on some biochemical and physical characteristics of cowpeas (Vigna unguiculata) during canning
Response surface methodology and central composite design for K=3 was used to study the combined effect of blanching time (0–12 min), soaking time (0–24 h) and sodium hexametaphosphate [(NaPO3)6] salt concentration (0–1%) on moisture, ash, leached…
Effect of roasting conditions on the browning index and appearance properties of pulp pre-conditioned and fermented cocoa (Theobroma Cacao) beans
Appearance is an important quality determinant of cocoa beans and it is used as standard criteria to establish the degree of fermentation and drying of the beans. Changes in browning index and colour (L* a* b*) during roasting of pulp pre-conditioned…
