Abstract: This study aimed to investigate the physicochemical properties, health-promoting benefits and rheological properties of an EPS produced by a novel probiotic Pediococcus pentosaceus M41 isolated from a marine source. P. pentosaceus M41 was able to produce an EPS with average molecular weight of 682.07 kDa. EPS-M41 consisted of arabinose, mannose, glucose and galactose with a molar ratio of 1.2:1.8:15.1:1.0. EPS-M41 structure could be proposed as →3)α-D-Glc(1→2)β-D-Man(1→2)α-D-Glc(1→6)α-D-Glc(1→4)α-D-Glc(1→4)α-D-Gal(1→ with arabinose linked at the terminals. At concentration of 10 mg.ml

Abstract: Camel (CM) milk is used in variety of ways however, it has inferior gelling properties compared with bovine milk (BM). In this study, we aimed to investigate the physicochemical, functional, microstructural, and rheological properties of low-moisture part-skim (LMPS) mozzarella cheese, made from BM, or BM mixed with 15% CM (CM15%) or 30% CM (CM30%), at various time points (up to 60 d) of storage at 4°C after manufacture. Low-moisture part-skim mozzarella cheeses using CM15% and CM30% had high moisture and total Ca contents, but lower soluble Ca content. Compared with BM cheese, CM15% and CM30% LMPS mozzarella cheese exhibited higher proteolysis rates during storage. Adding CM affected the color properties of LMPS mozzarella cheese manufactured from mixed milk. Scanning electron microscopy images showed that the microstructure of CM15% and CM30% cheeses had smooth surfaces, whereas the BM cheese microstructures were rough with granulated surfaces. Low-moisture part-skim mozzarella cheeses using CM15% and CM30% showed significantly lower hardness and chewiness, but higher stringiness than BM cheese. Compared with BM cheese, CM15% and CM30% cheeses showed lower tan δ levels during temperature surges, suggesting that the addition of CM increased the meltability of LMPS mozzarella cheese during temperature increases. Camel milk addition affected the physicochemical, microstructural, and rheological properties of LMPS mozzarella cheese.

Abstract: This study is aimed at developing a thermoplastic composite based on date pit powder waste for use as a thermal insulator in building industries. Date pits are the by-product of date stoning, either for the production of pitted dates or for the manufacture of date paste. The date pit powder (DPP) used in this study was obtained from the UAE University farm in Al Foah, UAE. DPP waste contents ranging from 0 wt.% to 50 wt.% were used to prepare the DPP-polystyrene composite. Date pit powder was mixed with polystyrene using a melt extruder, and then the mixture was transferred to the hot press to produce the final s le. The thermal and physical characteristics of the produced composites were measured experimentally and analyzed theoretically in terms of date pit and polystyrene properties. The characterized properties of the DPP-polystyrene composites, namely, density, thermal conductivity, water retention, thermal stability, and microstructure, showed that a stable composite material with insulation and construction capacity can be formed by the addition of date pit powder to the polystyrene matrix. The theoretical modeling of the measured thermal conductivity and the scanning electron microscope (SEM) monographs supported the hypothesis of date pit agglomeration in the composite matrix. The prepared composites showed low thermal conductivity (0.0515-0.0562 W / m K at 25°C) and very low density (457-630 kg / m 3 ), thus demonstrating their potential for use as a thermal insulator for building materials. In addition, replacing one-third of the classical construction wall content with DPP-polystyrene composite showed promise for constructive applications as a thermal insulator with 85% reduction in the overall thermal conductivity. Indeed, these properties are similar to those of other conventional insulating materials. This will lead to produce an inexpensive insulation material that exploits a common waste product in date fruit-producing countries.

Abstract: Camel milk (CM) can be used as an ingredient to produce various dairy products but it forms weak rennet-induced and acid-induced gels compared with bovine milk (BM). Therefore, in this study, we aimed to investigate the effect of blending bovine milk with camel milk on the physicochemical, rheological ( litude sweep and frequency sweep), and microstructural properties of low-fat akawi (LFA) cheese. The cheeses were made of BM only or BM blended with 15% (CM15%) or 30% (CM30%) camel milk and stored at 4°C for 28 d. The viscoelastic properties as a function of temperature were assessed. The LFA cheeses made from blended milks had higher moisture, total Ca, and soluble Ca contents, and had higher pH 4.6-water-soluble nitrogen compared with those made from BM. Analysis by scanning electron microscopy demonstrated that the microstructures formed in BM cheese were rough with granular surfaces, whereas those in blended milk cheeses had smooth surfaces. Hardness was lower for LFA cheeses made from blended milk than for those made from BM only. The LFA cheeses demonstrated viscoelastic behavior in a linear viscoelastic range from 0.1 to 1.0% strain. The storage modulus (G') was lower in LFA cheese made from BM over a range of frequencies. Adding CM reduced the resistance of LFA cheeses to flow as temperature increased. Blended cheeses exhibited lower complex viscosity values than BM cheeses during temperature increases. Thus, the addition of camel milk improved the rheological properties of LFA cheese.

Abstract: In this work, an investigation of the mechanical behavior of thermoplastic polystyrene (PS) composites containing date pit powder (DPP) is presented. DPP waste contents ranging from 0 wt% to 50 wt% were used to prepare the PS composite. The experimental results revealed that the addition of DPP to the PS matrix decreased the compressive, tensile, and flexural strengths and moduli of the composite. The reduction in the composite’s compressive strength was minimal with filler contents up to 30%. The DPP-PS composites demonstrated superior tensile strength (1.12–0.34 MPa), compressive strength (11.58–2.31 MPa), and flexural strength (21.10–2.37 MPa) when compared with the commonly used insulating materials and comparable to some construction materials. The negative impact of DPP on the mechanical properties of PS was attributed to the agglomeration of the natural fillers creating stress concentration points, as well as poor compatibility between the fillers and the PS matrix. Alkaline treatment of DPP with sodium hydroxide solution enhanced marginally the compressive strength (by 4.2%) and effectively the tensile (by 190%) and flexural strength (by 55%) of all prepared composites. The scanning electron microscopy micrographs demonstrated that the treatment effectively changed the surface roughness of the date pit particles and enhanced the interference between the fillers and the PS matrix. Thermogravimetric analysis and Fourier transform infrared spectra of the treated filler indicate that the observed improvement in adhesion was due to removal of hydrophilic components from DPP.
