Characterization dataset for pre- and post-irradiated shrimp waste chitosan

Abstract

This dataset presents morphological features, elemental composition and functional groups of different pre- and post-gamma (γ)-irradiated chitosan (10kGy & 20kGy) prepared from shrimp waste. The γ-irradiated chitosan was characterized using Fourier transfer infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analyses. Thermogravimetry/differential thermal analysis (TG/DTA) were performed using Perkin Elmer Pyris Diamond DSC with a heating rate of 10 °C/minute and dynamic synthetic atmospheric air set at flow rate of 100 ml/minute. We observed γ-irradiated chitosan to have shorter polymer size, small pores and compacted structure with active alkyl and hydroxyl groups when compared to non-irradiated chitosan. Our data provides baseline understanding for structure of shrimp chitosan after 60 Co exposure which means, the biopolymer becomes more stable and is considered suitable for vast food industry applications.

Synthesis and Characterization of Diosgenin Encapsulated Poly-ε-Caprolactone-Pluronic Nanoparticles and Its Effect on Brain Cancer Cells

“…The diffraction patterns of PCL, Diosgenin, and Diosgenin-loaded nanoparticles (PCL-F68-D-NPs) were determined using a Phillips X'Pert Pro Powder X-ray diffractometer (XRD) (PANalytical, Almelo, The Netherlands). The samples were scanned from 2θ = 5 • to 60 • using a beam of Cu Kα radiation of wavelength, λ = 0.1542 nm, operated at 45 kV, 40 mA [41,42].…”

Sustainable Upcycling of Fisheries and Aquaculture Wastes Using Fish-Derived Cold-Adapted Proteases

“…The enzymatic hydrolysis process for shellfish wastes produces protein hydrolyzates, oils and deproteinized shells ( Figure 1 ). The shells can further be processed into chitin (and/or chitosan) which is a biocompatible, non-toxic and biodegradable polymer with a range of usable applications ( 11 ).…”

Amylases: Biofilm Inducer or Biofilm Inhibitor?

“…Amylase is an important group of enzymes, which are classified into α, β, γ subtypes, isoamylase, glucoamylase, and others. α and β-amylase have the potential to catalyze the hydrolysis of chitosan ( Rokhati et al., 2013 ) and reduce its molecular weight, which makes it more soluble ( Pati et al., 2020a ) and thus may lead to diversified applications ( Pati et al., 2020b ). Since the discovery of the first amylase by Anselme Payen, in 1833 ( Krikorian, 1970 ), many more have been found within living systems that have specific substrates ( Guzmàn-Maldonado et al., 1995 ; Gupta et al., 2003 ).…”
