Combined with multivariate calibration methods, near-infrared (NIR) spectroscopy is a non-destructive, rapid, precise and inexpensive analytical method to predict chemical contents of organic products. Nevertheless, one practical limitation of this approach is that performance of the calibration model may decrease when the data are acquired with di...
Le collage structural est l’assemblage de deux ou plusieurs matériaux via un adhésif. Cette technique s’impose de plus en plus dans l’industrie grâce à ses nombreux avantages tels que l’amélioration de la performance globale des assemblages, l’optimisation de la définition des structures et la simplification de certains processus industriels. Toute...
Beninese smallholders associate food crops and cash crops with immature oil palms to reduce field maintenance costs and gain income before the palms reach productive phase. Little is known about the effects of these crops on the nutritional status and growth of the palms in their immature phase even though the yield of adult palms can be affected b...
Plants can detect the quality, quantity and direction of light and use it as a signal to adapt their morphogenesis and growth. Thus depending on their light transmission, coloured nets used to protect plants from pests and limit irradiance can also impact plant growth and production. Tomato plants have been grown under blue or red nets transmitting...
Kava is a non-alcoholic beverage prepared by cold water extraction of the ground roots and stumps of Piper methysticum Forst. f. Kava contains flavokawains (FKs) which have been suspected of being potentially cytotoxic. Current HPLC protocols are not adapted to high-throughput quantification before export. The objectives of the present study were (...
Introduction – Piper borbonense from Reunion Island is an overlooked wild pepper that remains unutilized today. The purpose of this multidisciplinary work was to study its anatomy, morphology and biochemical composition with a view to its possible commercial development. Materials and methods – We determined its biochemical composition using, notab...
The purpose of this review is to support breeders and food scientists by examining research carried out on end‐user preferences for gari and its derived dough product, eba, in Africa. The review focused on gari regarding the physical and chemical composition of raw cassava roots, methods of storage, the composition of gari with or without enrichmen...
The latex collected from the Hevea brasiliensis tree is today the only commercial source of natural rubber (NR), the cis-1,4-polyisoprene polymer, a strategic raw material. The Hevea latex is a very complex material both in its structure and composition. In terms of structure, it is a colloidal dispersion where various micrometric objects, mainly r...
High-performance liquid chromatography with diode array (HPLC-DAD) and liquid chromatograph triple quadrupole mass spectrometry (HPLC-MS/MS) were used to characterize raw and fermented coffee pulps in terms of their phenolic composition and caffeine content. The qualitative analysis showed no significant differences between the raw and the fermente...
Eucalyptus trees have been adapted to the Tunisian climate. Now, they need to be economically valued. Tunisian Eucalyptus have great technological properties allowing us to use them as wooden material. However, there is large variability in the natural durability between heartwood Eucalyptus spp. The wood sustainability assessment provides reliable...
