Study of the shelf life of beetroot dye with and without preservatives Asian Dyer, 2024
Effect of extraction conditions on colour content from raw beetroot Tanveer Malik, Shamayita Patra Indian Journal of Fibre and Textile Research, 2024 In the present study, a preliminary investigation on extraction and optimization of red colour from raw beetroot has been conducted to optimize the dye extraction process, the extraction parameters, viz temperature is varied from 6 to 70 °C, time from 30 to 120 min and medium pH from 3 to 11. At 45°C temperature, 90 min extraction time and 5 pH, the maximum colour extraction is achieved, at this optimum condition, the maximum colour yield (2.49 ± 0.08 g/100ml) is obtained. It is observed that at ≥47.5°C the chromophore of beetroot dye is denatured as can be seen by the value of λ max, which is changed form 530 nm to 430 nm at ≥47.5°C .
Design and development of chitosan-based textiles for biomedical applications Chetna Verma, Manali Somani, Ankita Sharma, Pratibha Singh, Surabhi Singh, Shamayita Patra, Mukesh Kumar Singh, Samrat Mukhopadhyay, Bhuvanesh Gupta Smart and Functional Textiles, 2023 Chitosan (CS) is considered to be one of the most abundant and prominent biopolymers, exhibiting excellent physicochemical properties such as hydrogel nature as well as anti-microbial and haemostatic nature. Moreover, its inherent properties make it suitable for wound healing applications and designing anti-microbial polymeric systems. CS can also be combined with other polymers to enhance its performance in wound care. Further, it may be immobilized on textile support for the development of bioactive surfaces for numerous biomedical applications. The haemostatic nature of the CS-based fabric also helps in designing materials for controlling excessive bleeding in patients. This chapter is focused on utilizing functional CS to yield more effective therapies and vastly extend human health span.
Effect of extraction solvent composition on concentration yield of beetroot dye Asian Dyer, 2023
A novel observation: effect of anionic gelatin nanoparticle on stromal cells Shamayita Patra, Piyali Basak, Pratik Das, Samrat Paul Journal of Biomaterials Science Polymer Edition, 2023 Biocompatible nanoparticles are very popular in health science research. Biomolecule carriers for wound healing and tissue engineering are two main applications among many others. In many instances, these structures come in direct vicinity of cells and govern cell behaviour and responses. In this study, gelatin nano/submicron structures were synthesized by binary nonsolvent aided coacervation (BNAC) method at pH ranging from 3 to 11 with an intention to employ in skin tissue regeneration. Effect of pH over morphology and the surface composition with respect to its ionic composition were studied. Further, the initial toxicity was assessed against peripheral blood mononuclear cells (PBMC). pH 7 was found to be the optimum for synthesis of gelatin nanoparticles (GNPs) with minimum particle size. Positive cell viability of 103.14% for GNPs synthesized at pH 7 was observed. It may be due to the minimum difference between cumulative negative and positive charge (CNCP) ratio of 1.19. Finally, effect of the gelatin nanoparticles over L929 mouse fibroblast cells were assessed through MTT assay. It has resulted in 122.77% cell viability.

Effect of Okra Plant Lifespan upon Optical Properties of Okra Fibers P. K. Gupta, S. Maiti, Shamayita Patra, R. V. Adivarekar Journal of Natural Fibers, 2022 The present research study has been made to identify the effect of the okra plant lifespan upon the optical appearance of the yielded fibers. 90 ± 10 days, 120 ± 10 days, and 160 ± 10 days matured crop waste were subjected to two different retting conditions. For this study, stagnant water retting conditions and running water retting conditions were approached. Optical properties such as whiteness index, yellowness index, and brightness index of yielded okra fibers were measured by spectrophotometer. The study revealed that for both the retting conditions, the whiteness and the brightness index increased with the retting period up to a certain level, i.e., approximately 5–15% improvement for the whiteness index while approximately 10–40% improvement for the brightness index. While the yellowness index mostly showed a reverse effect with the retting period. The reduction in the yellowness index was approximately 2–7%. However, the effect of the retting period got saturated after a certain retting period, i.e., in between 17 and 25 days.Okra fiber yielded from both 90 ± 10 days and 120 ± 10 days matured okra plants showed similar optical properties, but better whiteness index than fiber yielded from 160 ± 10 days matured okra plants. In this research study, similar optical properties were observed for the fibers yielded from both the retting conditions.
Effect of Okra Plant Lifespan upon Tensile Properties of Okra Fibers P.K Gupta, S. Maiti, S. Patra, R. V. Adivarekar Journal of Natural Fibers, 2022 This study has been carried out to identify the effect of the okra plant lifespan upon the tensile properties, that is, fiber bundle strength and elongation of the yielded fibers. 90 ± 10 days, 120 ± 10 days, and 160 ± 10 days matured crop waste were subjected to different retting conditions (retting duration and retting medium flow rate). Water was used as retting medium with two different flow rates (0 and 6.5 m/min). Five retting durations were taken for this study between 11 and 35 days. The bundle tenacity (gf/tex) and elongation at break (%) were measured by Instron automatic bundle strength tester for the extracted okra fibers. The study revealed that okra fiber extracted through the running water showed better tensile strength (at least 14% higher, range 14–80%) than fiber extracted through stagnant water retting conditions at every retting duration (11–35 days) for the different lifespans of okra plants. Okra fiber bundle tenacity continuously reduced with the retting period ranging from 11 to 35 days irrespective of okra plant lifespan and retting conditions. Improvement in tenacity was found from 90 ± 10 days to 120 ± 10 days okra plant lifespan, but no significant improvement was found after 120 ± 10 days okra plant lifespan. No significant effect of elongation at break (%) was found for the okra plant lifespan and retting conditions.
