Calcium carbonate nanoparticles of quail’s egg shells: Synthesis and characterizations

Abstract

Avian eggshell is a natural biomaterial that has been used as an alternative natural source of CaCO3 and is accessible in big amounts from egg manufacturing. This study was planned to estimate CaCO3 in quail’s eggshell because it has a probable use in the progress of a novel choice of many applications. Physical properties: mineralogical documentation of the natural eggshell nanoparticles were approved using XRD and FTIR to explore the chemical bond or molecular structure of the materials. Micrographs were obtained using FESEM/EDX and TEM to identify the morphology and size of nanoparticles. The results showed that quail eggshell was soft, with white to light sand color, and a smooth texture which allows good deposition of different color spots, from black to brown spots. The resulted of eggshells signifies almost 8.4% w/w of the overall weight (12.2) gram of quail egg and 91.60% w/w of the micropowder to the full weight of (0.94) gram of quail eggshell. The results presented that calcium is the main element in an eggshell; frequently occurs in a formula of CaCO3 and the crystal construction was almost pure calcite. FTIR spectra for quail eggshell demonstrated the existence of the out of plane bending, the asymmetric stretching, and the plane bending styles of the carbonate groups, specific of normal dolomite, situated at 873 cm–1, 1405 cm–1, and 710 cm–1, respectively. The FESEM and TEM for nanoparticles were shown calcite CaCO3 nanoparticles with an ordinary size of ≤ 100 nm for FESEM and with a variety size of ≤ 50 nm for TEM. Unfortunately, eggshell is an egg product manufacturing deposit. These incomes will let fast developments in proportional studies of the organic elements of avian eggshell and their purposeful consequences by usages of eggshell in nourishment and medicine which can be applied for many resolutions that diminish their consequence on environmental contamination.

A novel source of calcium: effects of calcium pidolate concentration on egg quality in aged laying quails (Coturnix coturnix Japonica)

“…Dietary calcium is necessary for both bird development and egg quality (Ahmed et al ., 2022). There is a close relationship between calcium metabolism and poultry aging (Manangi et al ., 2018; Zhao et al ., 2020; López et al ., 2021; Lee et al ., 2021), so determining the optimal levels of calcium in the diet is essential to ensure the economic viability of the production.…”

“…Further investigation of the constituent properties of CP was carried out by FTIR, as shown in Figure 4. The strong absorption peak at 1476 cm −1 is due to the anti-symmetric stretching vibration of the carbonate; The absorption peak located at 1079 cm −1 is due to the symmetric stretching vibration of the carbonate; The peak change at 859 cm −1 is attributed to the out-of-plane bending vibration of the carbonate, and the peak at 708 cm −1 is identified as the in-plane bending vibration of the carbonate [34,35]. The absorption peak at 3408 cm −1 is assigned to the stretching vibration of hydroxyl (-OH); The two successive peaks at 2982 cm −1 and 2917 cm −1 are due to the anti-symmetric stretching vibration of methyl (-CH 3 ) and the anti-symmetric stretching vibration of methylene (-CH 2 ), respectively; The weak absorption peak at 2844 cm −1 is attributed to the symmetric stretching vibration of methylene (-CH 2 ); The obviously peak at 2519 cm −1 is the combination frequency of anti-symmetric and symmetric stretching vibrations, and the peak locked at 1788 cm −1 is attributed to the stretching vibration of C=O [29,36,37].…”

Egg Shell: An Essential Waste Product to Improve Dietary Calcium Uptake

“…Enhanced bone strength, reduced pain feeling, and increased mobility is all signs of osteoporosis. ES calcium has a high bioavailability and has been shown to help with fragile fingernails, hair, lethargy, and asthma in both kids and young adults [6][7][8][9]. The present study looked into the nutritional profile of ES importance of calcium in the diet as well as the ingredients which are needed as support for calcium absorption.…”
