“…Bamboo is also known to store starch in the undifferentiated cells between vascular bundles (Wang et al, 2016). The extracted starch has been identified to have the A-type structure (Felisberto et al, 2020). However, since the presence of starch is seasonal, transient structural species that form during starch metabolism could have contributed to what we observe as well.…”

X-ray and neutron scattering have long been used for structural characterization of cellulose in plants. Due to averaging over the illuminated sample volume, these measurements traditionally overlooked the compositional and morphological heterogeneity within the sample. Here, a scanning tomographic imaging method is described, using contrast derived from the X-ray scattering intensity, for virtually sectioning the sample to reveal its internal structure at a resolution of a few micrometres. This method provides a means for retrieving the local scattering signal that corresponds to any voxel within the virtual section, enabling characterization of the local structure using traditional data-analysis methods. This is accomplished through tomographic reconstruction of the spatial distribution of a handful of mathematical components identified by non-negative matrix factorization from the large dataset of X-ray scattering intensity. Joint analysis of multiple datasets, to find similarity between voxels by clustering of the decomposed data, could help elucidate systematic differences between samples, such as those expected from genetic modifications, chemical treatments or fungal decay. The spatial distribution of the microfibril angle can also be analyzed, based on the tomographically reconstructed scattering intensity as a function of the azimuthal angle.

“…Note that the Young's modulus values of BV fibers vary in the interval [7.65 GPa–9.37 GPa] and are in the same order of magnitude as those of other varieties of bamboo present in the literature. 21 Young's modulus increases from inside to outside in any radial position. This observation was also made when studying the fibers of another variety of bamboo.…”

“…19,20 Studies of bambusa vulgaris along the plant (base, middle and top) have been made on the physico-chemical characterization of the starch extracted from three different parts of the young bamboo culm of bambusa vulgaris. 21 Based on the work already done on bamboo in general, it emerges that for the case of bambusa vulgaris, the researchers have not yet addressed work on mechanical properties or fibers along the bambusa vulgaris stem as well as the study of viscoelastic behavior. Usable as reinforcement in composite materials, it is necessary to bring out in this paper the characteristics of bambusa vulgaris (BV) fibers both on the physicochemical level by studying its microstructure, thermogravimetric analysis, density and on the mechanical plane through the determination of the Young's modulus, stress at failure, bending properties and the study of viscoelastic behavior.…”

In this study on characterization of bambusa vulgaris fibers from Cameroon (BV), we evaluated the linear density as well as the moisture uptake. With the help of SEM, the cross-sections were observed to be circular shapes; they increase from outside to inside in any transverse position along the stem. Also, the degradation temperature of BV was investigated with the aid of TGA and the result showed that the degradation temperature of BV fibers is between 366 °C and 380 °C. In addition, their Young's moduli in dynamic tensile test was determined and it was noticed that the Young moduli increase from inside to outside. The bending tests of BV fibers were carried out and enable the various parameters in zone 3/3. Finally, the creep behavior of BV fibers was studied and it was revealed that the 4-element Burger model describes very well this phenomenon and could help in well predicting fatigue behaviour of BV fibers reinforced composites.

“…This raw material presented as a light brown powder with a velvety texture and the extraction process had a yield of 27.35%. These results showed that the starch yield from mango seed kernel is like conventional starch sources, such as cassava (18.00-29.33%) [75] and nonconventional starch sources, such as tarap (17.8%) [76], banana (13.57-16%) [77,78], and bamboo (3.12-19.15%) [79][80][81]. The amylose content of starches plays a pivotal role in influencing various properties, such as gelatinization behavior, retrogradation tendencies, swelling capacity, and susceptibility to enzymatic action.…”

The agro-food industry plays a crucial role in enhancing living standards; however, inadequate losses and waste management persists as significant challenges within its processes. Particularly, mango and cheese processing generate substantial waste, leading to ecological disruptions, economic losses, and concerns related to food security and public health. To address these issues, this study was aimed at utilizing this waste to produce a high-quality ice cream base, thereby valorizing the discarded materials. This approach not only adds nutritional value but also contributes to food security and sovereignty. The raw materials (cheese whey, oil, and starch) were subjected to physicochemical characterization, leading to the development of three different ice cream base formulations. Subsequently, the ice cream bases were evaluated for their physicochemical, functional, and sensory properties. The findings of this study revealed that mango seed kernel and cheese whey waste contain valuable components that enable the creation of an ice cream base with excellent physicochemical, functional, and sensory properties. Moreover, this research showcases a promising solution for effectively valorizing food waste and generating value-added products such as ice cream, thus promoting sustainability and resource optimization within the agro-food industry.
