“…Novel pH responsive biopolymer lms made by immobilising the anthocyanin pigment from natural dyes have received great interest recently. [7][8][9][10][11] The pigment particles immobilised during evaporation and drying process. Immobilisation boosts the orientation of pigments are vertically within the lm layer and it is reported that sol gel method is a popular method for immobilisation of pigment.…”

“…Two main constituents of pH sensitive colorimetric lms are a solid base and a pigment to check pH change. Several intelligent pH sensitive biopolymer based lms were developed by using different biopolymers like starch 8,10,[12][13][14] bacterial nanocellulose, 8 chitosan, 15 methyl cellulose, 16 polyvinyl alcohol. 15 Recently natural colour pigments are focused more because they are eco-friendly compared to synthetic dyes.…”

“…En la Tabla 4 se puede observar que cada empresa podría ser una alternativa para el uso de sus subproductos en diferentes propósitos o aplicaciones. A excepción del contenido de lípidos, los valores de pH, BVT y NNP están muy relacionados con el manejo y sugieren cambios bioquímicos o microbiológicos están ocurriendo; sin embargo, por el pH per se no debe tomarse como referencia de calidad, pero al asociarlo con BVT, brinda herramientas suficientes para predecir la calidad de un producto pesquero (Ezati et al, 2019). Por lo tanto, con el presente estudio se confirma García-Sifuentes et al: Explorando diferentes subproductos considerados como / XXII (2): 61-69 (2020) la necesidad e importancia de mejorar las buenas prácticas de manejo de subproductos y de esta manera, aumentar las posibilidades de su utilización en aplicaciones relacionadas con el consumo humano indirecto o directo, dependiendo de la legislación, sobre todo con el sitio MM.…”

La producción y poco aprovechamiento de subproductos de los grandes centros de distribución en México causa problemas ambientales. Se exploró la composición fisicoquímica de distintos subproductos evaluando el pH, humedad, lípidos, ceniza, proteínas, nitrógeno no proteico, bases volátiles totales, hidroxiprolina y prolina en tres sitios (zonas) de muestreo durante tres meses diferentes, cada zona o sitio representó muestras diferentes, así: MM (mezcla de subproductos de diferentes especies), AT (subproductos derivados del enlatado de atún), TL (subproductos derivados del fileteo de tilapia). Se registraron diferencias en la composición química entre los tres meses de muestreo y entre los tres sitios evaluados. Los resultados mostraron que los componentes más importantes que se pueden recuperar son: proteínas, para el sitio MM, incluyendo el colágeno; lípidos y proteínas, para el sitio AT; colágeno y lípidos para el sitio TL. Los valores promedio de pH (7.89), humedad (72.75 %) y BVT (188 mg N/100 g) para el sitio MM, demuestran la necesidad de mejorar el manejo de los subproductos en ese sitio. Los subproductos de los tres sitios de muestreo mostraron ser una fuente alternativa de componentes importantes como proteínas que no son colágeno, colágeno, lípidos y cenizas, dependiendo del sitio. Sin embargo, es importante resaltar la necesidad de mejorar el manejo de los subproductos para lograr un mayor aprovechamiento.ABSTRACTThe production and under-utilization of by-products from the large distribution centers in México, promotes environmental problems. The physicochemical composition of different by-products produced by the large distribution centers throughout different months was explored evaluating pH, moisture, lipids, ash, proteins, non-protein nitrogen, total volatile bases, hydroxyproline and proline, in three places during three months, each place represented different sample, including: MM (by-products from different fish species), AT (by-products of tuna canning, and TL (tilapia by-products). There were differences in chemical composition among the three months and the evaluated places. Results showed that the most important components that could be recovered are proteins for MM, collagen, lipids and proteins for AT and collagen and lipids for TL. Average values of pH (7.89), moisture (72.75 %) and total volatile bases (188 mg N/100 g) demonstrate the need of improving the by-products management in the MM place. By-products from the three evaluated places showed be an alternative source to obtain important components including non-collagen proteins, collagen, lipids, and ash depending on the sampling place. However, it is important to highlight the need of improving the handling of by-products to achieve greater exploitation.

“…[6] Colour of alizarin changes with the pH of the solution, and thus making it a pH indicator. [7] Figure 1 portrays the structure and characteristic features of alizarin red S. In humans, ARS causes some adverse effects including skin, lungs and eye irritations, vomiting, nausea, and hypersensitivity. [8] It can stain contact lenses if interacted resulting in contact dermatitis.…”

Water pollution is one of the major global challenges today. Water bodies are contaminated by the heavy release of waste effluents of textile industries, which includes intensively colored dye pollutants. Herein, a ternary nanocomposite of bismuth copper selenide with small particle size and ternary metal selenide (TMS)‐chitosan microspheres (TMS‐CM) of the spherical porous surface were successfully synthesized. SEM, XRD, EDX, FTIR, and UV/Vis spectrophotometry analysis revealed the structural and morphological characteristics of the newly synthesized nanocomposites. SEM imaging showed the average diameter of TMS nanoparticle to be 33 nm. The crystal size was calculated as 6.33 nm and crystalline structure as orthorhombic using XRD findings. EDX confirmed the presence of Bi, Cu, and Se in the ternary nanocomposite. The bandgap of 1.8 eV was calculated from Tauc's plot for the TMS nanocomposite. SEM confirmed the successful synthesis of spherical TMS‐CM microspheres of porous surface morphology with an average size of 885.6 μm. The presence of chitosan microspheres in the synthesis of TMS nanocomposite was identified by FTIR spectral analysis. Furthermore, highly efficient photocatalytic degradation (up to 95.4%) of ARS was achieved within 180 min at pH 4.0 using 0.5 g of TMS‐CM in sunlight. The first‐order kinetic model fitted well to the photocatalytic decontamination of ARS using TMS‐CM with a rate constant of 6.1x10−2 min−1. The TMS‐CM gave attractive results and high efficiency in photocatalytic degradation of ARS dye after reusing and regeneration of up to seven successive cycles. The newly synthesized nanophotocatalyst could be efficiently used for the decontamination of dye polluted water from textile industries.
