“…Natural Ca sources are of interest because they contain not only Ca but also other elements (e.g., Sr and F), which may have a positive effect on bone metabolism (Olgun et al, 2015). Concentrations of other elements (Na, K, P) in eggshells are very low compared to the daily recommended allowance (Neunzehn et al, 2015). Studies have proven natural calcium supplement safety -eggshell powder has a smaller amount of V, Cr, Pb, Al, and Cd compared to oyster shells or purified CaCO3 (Schaafsma et al, 2000).…”

Today's food ration does not often contain enough vitamins, fibre, macro-and micronutrients, especially calcium. Research aim: to study possibilities for the use of the eggshell powder in the production of bread enriched with calcium. For the study, the free-range hen eggshells, main components of which are inorganic salts, were used. The eggshells have been washed, dried and ground. To avoid changes in the texture of bread, the solubility of the eggshell powder was tested by incorporating different quantity of eggshell powder (2.5 g,) into rye sourdough with Lactobacilli for 12 hours. After discovering good solubility of the eggshell powder in the fermented leaven samples, sourdough of rye bread was prepared (control, 2.5, 5.0, 7.5, 10.0, 12.5 g addition of eggshell powder) and using them six samples of wheat bread were baked. To estimate an influence of eggshell powder on a product quality and acceptability of bread by consumers, sensory evaluation for bread samples was carried out. Besides porosity, moisture content, acidity, the actual acidity, specific volume of bread were defined, and also nutritional value and amount of calcium were calculated. The study showed that when making the bread enriched with calcium, it is recommended to add an eggshell powder to rye sourdough with lactic acid bacteria. The sensory evaluation shows that the bread with eggshell powder had a better appearance of the crust, colour of the crumb, flavour and overall acceptability compared to control bread, however the taste and flavour remained similar or got worse. By increasing the amount of eggshells, bread porosity and specific volume of bread increased, while acidity and active acidity decreased. Bread containing 5.0 g of eggshell powder was marked as a bread of the best quality.

“…A vitro study, carried out by Neunzehn et al, (2015) exhibited the high capability of the blend of eggshell particles and hyaluronan as essential segments for bone recovery and tissue designing. These results were in accordance with Krithiga andSastry, (2011) andBee, (2011) who reported that the utilization of chicken eggshell powder may be useful, it could expand bone thickness and diminish torment in patients with osteoporosis.…”

Bone mass declines alongside maturing, particularly for ladies after menopause as a result of diminishing estrogen emission together with low calcium consumption. This examination was directed to examine the impact of powdered cuttlebone, crab shell and eggshell, on female rats with induced osteoporosis. Fifty adult female albino rats, of (200 ± 10 g) were haphazardly divided into five groups, the first group, negative control group (-ve) fed on basal diet only, the other four groups (10 rats each) were fed on basal diet containing 100 mg prednisone acetate as source of glucocorticoid/ kg diet to induce osteoporosis for two weeks. One group of them was selected as a positive control group, the other three groups were fed on prednisone acetate diets containing powder of cuttlebone, crabshell and eggshell, at the level of 2.5% individually. Blood samples and femur bones were gathered for measure both serum and bone markers of osteoporosis. The results indicated that, supplementation with powder of cuttlebone, crabshell and eggshell significantly (P<0.05) increase of Ca and P in serum of osteoporotic rats. There were a significant increment in serum free thyroxin (T4) and a significant decrease in parathyroid hormone (PTH). Femur bone mineral content (BMC) and bone mineral density (BMD) were likewise increased as compared to positive control group. In addition, liver functions were significantly (P<0.05) improved compared to the positive control group, while serum lipid profiles were significantly decreased. These results recommend that sustaining postmenopausal rats with osteoporosis on diets supplemented with powder of cuttlebone, crab shell and eggshell instigated an enemy of osteoporotic impact. This impact may be due to upgrade of bone arrangement and direction of some metabolic hormones which control calcium. Therefore, it could be recommended using powder of cuttlebone, crabshell and eggshell for postmenopausal women suffering from osteoporosis.

Factors Affecting the Particle Size of Bio-Calcium Carbonate Synthesized from Industrial Eggshell Waste

Calcium carbonate is broadly used as a catalyst support, filler, additive, and reinforcement in several types of industry e.g. chemical, food, and biomedical industry. Recently, eggshell waste has attracted much attention for the purpose of calcium carbonate production due to its compost about 96% calcium carbonate. However, direct use of egg shells as filler material can probably cause product defects. In this research, calcium chloride was extracted from chicken-eggshell waste followed by precipitation of micron size calcium carbonate. The effect of agitation time, the initial concentration of calcium chloride and synthesis temperature on particle size, and selected physicochemical properties of this precipitated calcium carbonate (PCC) were investigated. Scanning electron micrographs of the prepared materials illustrated that all of the PCCs obtained from these experiments exhibit uniform-round shape. The laser diffraction results show that the median size of the PCC particles increased significantly from about 6 µm to 19 µm with increasing agitation time and with decreasing initial concentration of calcium chloride. However, increasing the synthesis temperature from 30°C to 160°C only slightly increased the median size of the PCC particles. The results of X-ray diffraction indicated that both agitation time and initial concentration also have an effect on the crystalline morphology of the PCCs. In addition, calcite crystalline phase became dominant over the other crystalline phases when agitation time and initial concentration were increased. In comparison, PCCs synthesized from this eggshell waste have much smaller median particle size than commercial calcium carbonate. Furthermore, the purity of the PCC derived from shell waste was comparable to commercial calcium carbonate. This facile synthesis is environmentally friendly and cost effective.
