“…In Table 4, higher values of WAC and OAC were observed compared with other seeds such as talipot, pink pinion, and Cucurbita fisifolia (1.70, 1.07, and 1.4 g H 2 O/g sample, respectively), as reported by various authors (Navaf et al, 2020;Pensamiento-Niño et al, 2019;Rodríguez-Miranda et al, 2016). These differences are due both to geographical conditions and to the process of obtaining flour, due to the pressure and temperature exerted.…”

“…The Leucaena flour presented with an Aw of 0.35, which indicates that the Leucaena flour has high storage stability. It also showed an alkaline pH, but this value was below that reported for other seeds such as pink pinion seeds (7.23) reported by Pensamiento-Niño et al (2019), and Leucaena grown in Pakistan (5.6), ebony meal (5.96), and talipot palm meal (5.44) reported by Afza et al (2007), Hernández-Santos et al (2015 and Navaf et al (2020), respectively.…”

“…In parameter b*, a higher value was shown compared to that reported for the flours of a pink pinion (b* 16.62), talipot palm (b* 5.36), and cowpea (b* 13.14), and below the value reported for the flour of Terminalia chebula (b* 29.57). Likewise, Leucaena flour showed greater color saturation compared to pink pinion, talipot palm, and cowpea flours reported by Pensamiento-Niño et al ( 2019), Navaf et al (2020), andHamid et al (2015), respectively. For hº, a high value was also observed, indicating that the Leucaena flour shows a light brown color as indicated in the color chart (Table 4).…”

“…Regarding the color (Table 4), the L* of the Leucaena flour was higher than that reported by Pensamiento-Niño et al (2019) in pink pinion flour (L* 51.59) and by Pathak et al (2019) in Terminalia chebula flour (L* 54.89) and below that reported by Navaf et al (2020) and Hamid et al (2015) in talipot palm flours (L* 89.9) and cowpea (L* 85.24), respectively. In parameter a*, the values reported for pink pinion and Terminalia flours were higher (a* 7.85 and 6.40, respectively) than those found for Leucaena (Table 4).…”

The objective of this investigation was to study the physical, tecno-functional, chemical, and thermal properties of the Leucaena leucocephala seed. The physical properties revealed that the pod had an average weight of 2.14 g, a length of 13.67 cm, and an average of 20 seeds per pod. The seed had an average weight of 0.07 g with a volume of 30.02%. The sphericity was 52.14%, ovoid in shape, and presented with an apparent density and real density of 0.81 and 0.68 g/cm 3 , respectively, and a porosity of 15.64%. The seed had a green hue, whereas the flour had a light brown hue. The seed presented with a high-fat content of 31.78 g/100 g, protein of 26.56 g/100 g, and fiber of 15.49 g/100 g. The flour showed a water absorption capacity of 4.64 g/g, water solubility capacity of 16.20%, water activity of 0.35, oil absorption capacity of 2.03 g/g, and emulsifying capacity of 48.06%. It also showed foam formation ability (48.06%), gelling capacity (4.00%), swelling power (4.5-5.2%), and a pH of 6.7. The thermal properties showed the presence of three endodermic peaks, indicating the presence of protein-amylose and lipid-amylose interactions, in addition to the gelatinization temperature of the starch present in the flour.

“…3 In order to compete with fossil-derived materials, biopolymers must improve certain properties to be considered a viable alternative to conventional plastics. 4,5 One such property is their poor heat resistance. Films made from a combination of biopolymers typically have better properties than those made from a single biopolymer.…”

Addressing problems due to conventional plastics requires a comprehensive approach involving waste reduction, improved waste management practices, and the development of sustainable alternatives to conventional plastics. In this study, a system was designed that can decorate cellulose nanofiber with silver nanoparticles (AgNP) and then used as a reinforcing agent in thermoplastic starch matrix. The composites were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM) and transport properties. The morphology and chemical modification of cellulose nanomaterials with silver nanoparticles were confirmed by FESEM, TEM and FTIR and the results indicated proper adhesion of silver nanoparticles in cellulose nanofiber. The addition of AgNP decorated cellulose nanofiber on thermoplastic starch matrix could effectively reduce cracks and pores and improves the overall performance of nanocomposite films. The unique properties of starch nanoparticles make them a promising candidate for diverse applications, showcasing their potential as a sustainable and versatile nanomaterial.

In this work, films based on three different starches have been developed and modified by adding silver nanoparticles. We examined the films in terms of their mechanical properties, barrier properties and environmental toxicity to plants and invertebrates. For the toxicity studies, we used the following seeds: Berny rapeseed, Brassica napus; Salvia hispanica—chia, Salvia hispanica; and Karo narrowleaf lupine, Lupinus angustifolius. The invertebrates used for toxicity studies were Daphnia pulex, Tubifex tubifex, Chaoborus sp. (larva), Chironomus aprilinus, and Artemia sp. The tests showed that KD, TD, and ZD films were the most phytotoxic, which was confirmed by the percentages of germination and growth inhibition calculated for all test plants. K2D, D2T, and Z2D films exhibited considerable toxicity to lupine and chia. The conducted biotoxicity tests concerning the modified films and their effect on the selected invertebrates showed that Daphnia pulex and Artemia were highly sensitive to the tested factors. Only Chaoborus sp. (larva) exhibited total resistance to the tested films, which did not cause death of the organism in any case. Biotests on invertebrates and plants developed and used in this research can be successfully used to determine the toxicity of other substances.
