“…Jackfruit seeds starch has high amylose content (24-32%), high gelatinization temperature (75-85°C), thermomechanical shear tolerance, low lipid content, acidity resistance, higher temperature and pulp viscosity, and lower pulp breakage than the gels produced by cassava and potato starches (Rengsutthi and Charoenrein 2011;Santos et al 2009). The production of bioplastics based exclusively on starch requires the addition of plasticizers, since these films have low machinability, that is, they are difficult to adapt to the conventional processes of package production.…”

Biodegradable films based on starches from different botanical sources exhibited physicochemical and functional properties which were related with the starch characteristics. However, had inadequate mechanical properties and were hard and brittle. In this research, jackfruit seed starch plasticized with glycerol were developed and characterized. The starch and glycerol concentrations ranged from 2 to 6% w/w and 20 to 60 g/100 g starch, respectively. Bioplastics were obtained by the casting method and characterized in terms of color, mechanical properties, solubility, water vapor permeability (), morphology and free energy of the hydrophobic interaction. Electronic micrographics showed the presence of some intact starch granules. The bioplastics were hydrophilic and those of 6% starch and 40% glycerol were the most hydrophilic ([Formula: see text] = 41.35 mJ m). The solubility of the films presented a direct relationship with the starch concentration ranging from 16.42 to 23.26%. Increased opacity and color difference were observed with increasing starch concentration. The ranged from 1.374 × 10 to 3.07 × 10 g m/day m which was positively related with the concentration of starch and glycerol. Tensile strength, percent elongation and Young's Modulus indicated that the jackfruit starch and glycerol provided a film with good mechanical properties. The results replaced that jackfruit starch can be used to develop films, with low opacity, moderate and relatively high mechanical stability, by using glycerol in the gelatinized starch dispersions.

“…The starch granules ( Figure 3 A,B) had a rounded and irregular bell shape ranging from 4–6 μm. Starch extracted from Brazilian jackfruit is typically of this size and form [ 61 ], whereas jackfruit starch extracted from Thai, Malaysian, or Chinese jackfruit is different in size and shape [ 26 ]. The variations in granule morphology are influenced by differences in cultivars and environmental factors [ 62 ] and affect starch’s functional characteristics [ 26 ].…”

Due to the physical, thermal, and biological properties of silver nanoparticles (AgNPs), as well as the biocompatibility and environmental safety of the naturally occurring polymeric component, polysaccharide-based composites containing AgNPs are a promising choice for the development of biomaterials. Starch is a low-cost, non-toxic, biocompatible, and tissue-healing natural polymer. The application of starch in various forms and its combination with metallic nanoparticles have contributed to the advancement of biomaterials. Few investigations into jackfruit starch with silver nanoparticle biocomposites exist. This research intends to explore the physicochemical, morphological, and cytotoxic properties of a Brazilian jackfruit starch-based scaffold loaded with AgNPs. The AgNPs were synthesized by chemical reduction and the scaffold was produced by gelatinization. X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscopy coupled with energy-dispersive spectroscopy (SEM-EDS), and Fourier-transform infrared spectroscopy (FTIR) were used to study the scaffold. The findings supported the development of stable, monodispersed, and triangular AgNPs. XRD and EDS analyses demonstrated the incorporation of silver nanoparticles. AgNPs could alter the scaffold’s crystallinity, roughness, and thermal stability without affecting its chemistry or physics. Triangular anisotropic AgNPs exhibited no toxicity against L929 cells at concentrations ranging from 6.25 × 10−5 to 1 × 10−3 mol·L−1, implying that the scaffolds might have had no adverse effects on the cells. The scaffolds prepared with jackfruit starch showed greater crystallinity and thermal stability, and absence of toxicity after the incorporation of triangular AgNPs. These findings indicate that jackfruit is a promising starch source for developing biomaterials.

“…Por serem ricas em amido, proteína e fibras, as sementes de jaca têm sido cada vez mais investigadas e propostas para alimentação humana (Feitosa et al, 2017;Leite et al, 2019;Santos et al, 2012;Waghmare et al, 2019). A composição de amido nas sementes foi relatada, por exemplo, por Santos et al (2013) para duas variedades de jaca obtidas na região sudoeste da Bahia como em torno de 30 % (p/p), sendo que as sementes corresponderam a 12-13 % dos frutos. Devido às propriedades diferenciais do amido das sementes de jaca (Madruga et al, 2014;Santos et al, 2009;Rodrigues et al, 2020;Zhang et al, 2021) em relação aos amidos mais tradicionais, ele também tem sido proposto para diferentes aplicações tecnológicas como: alimentos, embalagens e recobrimentos, fermentação, etc.…”
