Edible films nanostructured with mesopouros silica nanoparticles or with its amino-functionalized derivative were prepared from seed bitter vetch proteins, before and after their crosslinking by microbial transglutaminase, and characterized for their physicochemical, morphological and bioactive properties. Film gas vs electric stove cost tensile strength and elongation at break significantly increased in the presence of both kinds of nanoparticles, even though the amino-functionalized ones resulted more effective, determining a two-fold increase of the mechanical properties. Transglutaminase-catalyzed protein crosslinking counteracted these nanoparticle induced effects while, conversely, it further increased film barrier properties to gases and water vapour obtained by nanoparticles alone. AFM and SEM analyses indicated a more compact structure of the nanocomposite film matrix with more evident continuous zones compared to control films, as well as an effect of transglutaminase in including more homogenously both nanoparticles into the crosslinked protein network. Finally, all films exhibited antimicrobial and antifungal activities gas 87 89 93, probably due to phenolic compound(s) present in the bitter vetch protein concentrate, and the addition to the film forming solutions of the bioactive oligopeptide nisin significantly enhanced these properties.

In this research work, a modified water displacement method (MWDM) was designed and used in addition to geometry method (GM) to measure the bulk r gas constant volume and then determine the bulk density values of asbestos ceiling board, cardboard paper, chalk, clay (compacted) and gypsum board that have been sun-dried to constant weight. The mean bulk densities determined by both methods were compared with the reference bulk density values of the same porous materials obtained in this work using standard test procedure in accordance with ASTM D6683-14. It was observed that, for all the tested porous materials, the percentage error in the mean bulk density values ranged from 2.3% to 49.6% when using GM and 0.9% to 5.7% by using the MWDM. Also, at 0.05 level of significance with a degree of freedom of 3, correlation coefficients of 0.7430 and 0.9955 were obtained in the cases of GM and duke electric orlando the MWDM respectively. Again, all other analyses performed similarly revealed origin electricity login that the mean bulk densities obtained by the MWDM only were in close agreement with their corresponding reference values, thereby implying that apart from being cost-effective, the MWDM is better than GM in terms of accuracy, reliability, and validity. More importantly, it is noteworthy that even if the glass cylinder available for use is ungraduated, this MWDM can be employed to obtain accurate, reliable and valid bulk density values of porous materials in order to enhance thorough physical characterization, proper selection and suitable applications of such materials.
