Sourcing and Comparative Study on Proximate and Characterisation of Chitin and Chitosan from the Biomass of Nigerian Shrimp and Crab Shells and Conversion to Glucosamine | Chapter 7 | Research Perspective on Biological Science Vol. 5

 

The most important biopolysaccharides for biochemical industries are chitin and chitosan. These chemical entities are nitrogenous polysaccharide polymers containing 2-acetamido-2-deoxyglucoside units. These products are useful in engineering, medicine, agriculture and other industrial uses. Over the past few years, these compounds have garnered significant recognition for their numerous potential applications in cutting-edge pharmaceutical research.

 

Glucosamine is a known drug for treating musculoskeletal problems and has been obtained from a set of amino polysaccharides. Despite their broad applicability, there is limited information in the Nigerian context regarding their extraction and utilisation from local sources.

 

The present study was aimed at isolation of chitin and chitosan from shrimp and crab wastes by chemical methods involving deproteinization, demineralisation at 1M concentration of HCl and NaOH depigmentation, filtration and Deacetylation with 50% NaOH at 100°C, where necessary. These were simultaneously converted to glucosamine by acid hydrolysis using 37% HCl for 1 hour. The yield of chitin was 17% for shrimp and 28.00% for crab. Deacetylation of chitin using 50% NaOH at 100oC resulted in 56% chitosan from shrimp and 71.10% from crab. The proximate analysis of chitin isolated gave rise to the following result: moisture 2.9%, ash 4.54%, lipids 2.1% and protein 3.3% for shrimp and moisture 4.03, ash 1.97%, lipid 1.73%, and protein 2.90% for Crab. These compounds were characterised using FTIR. In the infra-red spectrum, the shrimp chitin indicated an amide (I) band at 1614cm-1, while crab chitin indicated an amide (1) band at 1629 cm-1 whereas chitosan and glucosamine showed no amide band but hydroxyl and amino groups between the ranges of 3110-3595 cm-1 while crab showed absorption at 3565-3015cm-1. The results of these analyses, including the proximate analysis, compared well with literature values. There is a paucity of information in the literature about this type of study in Nigeria. This study has created awareness that these biomaterials from crustacean sources from Nigeria are technologically useful for conversion into useful products that can be used in Engineering, Medicine, Agriculture and other industrial products. This work provides a route for controlling pollution threats caused by fishing and canning sites. This is a case of creating Wealth from Waste.

Assessment of Biodegradable Blends of Poly(Vinyl Alcohol) and Chitosan for Food Industry and Biomedical Application | Chapter 04 | Current Topics on Chemistry and Biochemistry Vol. 1

 Due to the presence of two types of reactive primary and secondary hydroxyl groups, chitosan (CS), an amino polysaccharide, is a stiff polymer (-OH). It is also a biodegradable, biocompatible, non-toxic, safe, and antibacterial polymer, making it suitable for use in the food and biomedical industries. As a result, biodegradable films based on poly (vinyl alcohol) (PVA) and chitosan (CS) are being developed for usage in food packaging and biomedical applications. The goal of this research is to create a low-cost biodegradable PVA/CS film using a solution casting process with glutaraldehyde as the cross linking agent. Fourier transform infrared spectroscopy (FTIR) and microhardness techniques were used to investigate the intermolecular interactions between constituents of polymer blends and mechanical properties. The degrading characteristics of PVA/CS films were investigated using composting. PVA and PVA/CS mixes had different absorption bands in their FTIR spectra, showing interactions between the blend's components. The marten hardness (HM) value changed from 83.08 MPa in pure PVA to 142.18 MPa (maximum value) with chitosan component of 40% wt. Chitosan boosted the mechanical stiffness of PVA/CS blends by up to 40%, and the optimal combination for the maximum improvement in mechanical properties was determined. This is because blending causes an intermolecular connection between two polymers, which improves the blends' mechanical strength. As the amount of chitosan in the mix rose, the rate of degradation increased.

Bio-efficacy of Acacia auriculiformis against Bactrocera cucurbitae | Chapter 8 | Recent Research Advances in Biology Vol. 9

 Pesticides made of synthetic chemicals used in agriculture have caused massive difficulties, raising concerns about their impact on the environment and human health. It is necessary to set a limit on the usage of these dangerous compounds. investigation of chemical constituents of pure fractions obtained from A. auriculiformis against the selected pest, B. cucurbitae, to build a base for industrial applications and formulations of ready-to-use type pesticides for farmers Pesticide-contaminated food, air, and water resulted from traditional pest management practises. Bactrocera cucurbitae, the melon fruit fly, is resistant to active components of Acacia auriculiformis, an economically valuable medicinal shrub. The findings revealed that fractions of ethyl acetate extract have a potential effect against insect pests, as treatments reduced emergence, increased mortality, and lowered pest pupal weight. Flavonoids make up the bulk of the fractions, according to chemical analysis of the active components using several spectroscopic techniques (FTIR, NMR, LC-MS). Flavonoids, primarily apigenin, gallic acid, and catechin, were also found in fractions A1, A2, and A4, respectively. Insecticides as insecticides

Spectral, Thermal, Mineral and Phenolic Characteristics of Plant Seeds from Ten Families | Chapter 8 | Current Research Trends in Biological Science Vol. 2

Seeds are a main dietary component for humans and animals. In this work, the physical, spectral, thermal, mineral and phenolic characteristics of seeds from 47 species belonging to 10 families (Arecaceae, Amaranthaceae, Anacardiaceae, Asteraceae, Fabaceae, Lamiaceae, Malvaceae, Rutaceae, Sapindaceae and Sapotaceae) are described. The seeds had moisture and ash contents in the 1.6–12.9% and 1.0–5.5% range, respectively, and the seed coat represented from 12 to 85% of the seed weight, depending on the species. The protein, starch and oil-associated vibrations in the seeds were characterized by infrared spectroscopy. The thermal behavior of the seeds, which involved an initial dehydration step, followed by free/bound moisture and volatile extractives release, and by protein, starch and oil decomposition, was studied by thermogravimetric (TG) and differential scanning calorimetry (DSC) techniques, evidencing noticeable differences between families. The total polyphenol and mineral contents widely varied from 185 to 3441 mg/100 g and from 831 to 7904 mg/100 g, respectively. Cluster analysis was used to categorize seed potentiality in terms of mineral contents. Variations in seed proximate parameters, spectral, thermal, phenolic and mineral characteristics as a function of the family to which the seeds belong to are also discussed.
