“…The XRD patterns of samples illustrates the presence of three diffraction peaks at 2θ=14.93°, 16.9°, 22.4° and 34.8° corresponding to the (110), ( 110), ( 200) and (004) crystallographic planes, respectively. These are typical re ection planes characteristic of cellulose I structure [39]. However, this result con rmed that the chemical process used from preparation of bleached cellulose micro bers did not alter the structure of cellulose I presented initially in the raw material.…”

Recently more attentions are growing every day towards the valorisation of industrial by-product especially those generated through agriculture and food industries, as the demands of bio-based resources for the necessary transition from fossil hydrocarbon sources to natural based products are increasing. This paper focuses on the potential effect of chemical treatments and modification as well as fibers loading on the thermal, mechanical, and rheological behaviour of reinforced Polypropylene (PP). During this work, fibers were prepared using alkali and bleaching treatments and then characterized using different analysis such SEM, X-ray, FT-IR and TGA/DTG. The composite materials were elaborated using twin-screw extrusion followed by injection molding by mixing PP with 5 to 10 Wt.% of raw bagasse cane (RBC), alkali bagasse cane (ABC) and bleached cellulose microfibers (BCM) as well as cellulose microfibers with Styrene-(ethylene-butene)-styrene three-block co-polymer grafted with maleic anhydride (SEBS-g-MA) as coupling agent. The result achieved from this study shows that the use of different type of fibers led to significant decrease in thermal degradation of PP. The mechanical results show a significant improvement in Yung’s modulus, tensile strength and hardness of the reinforced PP compared to neat PP. However, a remarkable decrease was obtained in elongation at break and toughness for all reinforced composites compared to neat PP. Besides, higher and low torsion modulus was obtained for PP reinforced with BCM and SEBS-g-MA-BCM, respectively.Statement of Novelty: This study aims to valorise bagasse sugar cane by-product as a lignocellulosic source for the isolation of cellulose fibers. Innovative composite materials were prepared based on polypropylene.

Fluorescence techniques have been widely used by scientists to reveal valuable information from biological samples, but in food science, small progress is known due to the complexity of the samples. In this study, two different biological samples, garlic skin (GS) and agave fibers (AF), were used to evaluate the techniques of confocal laser scanning microscopy (CLSM) and total internal reflection fluorescence (TIRF) microscopy, to obtain valuable information on the fiber size of the samples. A compositional characterization with calcofluor white in CLSM was achieved, but a superficial characterization of the samples with TIRF was made, evidencing fiber sizes of 398.67 ± 48.47 nm and 677.38 ± 76.88 nm for GS and AF, respectively. This work reveals that only an untreated sample can be used with the two techniques in the same microscope. In addition, it is possible to characterize the sample only using a spatial field of research and which valuable information about the structure of the material is found. This work provides the opportunity to use advanced fluorescence techniques for elucidation of structures shortly before studied with these techniques.

“…Nanoparticles have also been obtained from residues of the "pulque" production. Leaves of the agave "pulquero" were pretreated with an alkaline solution (5% NaOH) and then milled using a high-energy planetary micro mill [48]. An average size of approximately 3 nm was achieved with this process, and the agave cellulose had a high degree of crystallinity, which had a great influence on the nanoparticle size.…”

Agave, commonly known as “maguey” is an important part of the Mexican tradition and economy, and is mainly used for the production of alcoholic beverages, such as tequila. Industrial exploitation generates by-products, including leaves, bagasse, and fibers, that can be re-valorized. Agave is composed of cellulose, hemicellulose, lignin, fructans, and pectin, as well as simple carbohydrates. Regarding functional properties, fructans content makes agave a potential source of prebiotics with the capability to lower blood glucose and enhance lipid homeostasis when it is incorporated as a prebiotic ingredient in cookies and granola bars. Agave also has phytochemicals, such as saponins and flavonoids, conferring anti-inflammatory, antioxidant, antimicrobial, and anticancer properties, among other benefits. Agave fibers are used for polymer-based composite reinforcement and elaboration, due to their thermo-mechanical properties. Agave bagasse is considered a promising biofuel feedstock, attributed to its high-water efficiency and biomass productivity, as well as its high carbohydrate content. The optimization of physical and chemical pretreatments, enzymatic saccharification and fermentation are key for biofuel production. Emerging technologies, such as ultrasound, can provide an alternative to current pretreatment processes. In conclusion, agaves are a rich source of by-products with a wide range of potential industrial applications, therefore novel processing methods are being explored for a sustainable re-valorization of these residues.
