“…This factor must be considered by nutritionists when using this food, since an imbalance between these minerals could compromise animal metabolism. Crustacean shells have between 30% and 50% of calcium-based compounds, such as carbonates and phosphates, which may limit their use in broiler diets (Suryawanshi et al, 2019). Calcium intake above requirements results in decreased plasma parathyroid hormone concentration through a negative feedback mechanism that would affect the absorption of Ca and P (Proszkowiec-Weglarz & Angel, 2013).…”

Shrimp waste meal (SWM) is a by-product from the processing of shrimp for human consumption. The value of SMW in feeding poultry is not well documented. The objective of this study was to determine the energy value and optimal inclusion level of SWM in the diet of growing chickens. A total of 180 one-day-old broilers were randomly assigned to five treatments with 0, 50, 100, 150 and 200 g/kg of SWM included in their diet. There were six replicates of six birds for each treatment. Dry matter intake (DMI) was not affected by the level of SWM that was fed. Retained dry matter varied from 72.39% in the diet that did not contain SWM to 66.97% in the diet with 200 g/kg of SWM. Nitrogen retention (NR) ranged from 54.70% to 70.10%; N ingested was between 18.71% and 24.03%. Energy intake ranged from 73.57% to 69.33% for the control and the diet with 200 g/kg of SWM, respectively. NR improved with increasing SWM inclusion levels. The apparent metabolizable energy (AME) and corrected apparent energy metabolizable (AMEn) ranged from 2928 to 2527 kcal/kg and 2774 to 2329 kcal/kg, respectively, relative to the control and 200 g/kg SWM diets. The energy consumption, in kcal/kg, of SWM consumed was AME = 2332-6.971 x SWM and AMEn = 2113-8.128 x SWM. High levels of SWM reduce the dry matter metabolization coefficient and metabolizable energy values in broilers during the growing phase, so it is recommended that up to 100 g/kg should be included, which would provide an AMEn of 1300.2 kcal/kg for free-range chickens in dry matter.

“…Therefore, in conclusion, the optimized concentration of HCl is 2.0 M for the demineralization process of the crab shell samples. Several previous studies conducted by several authors globally, however, the optimized acid concentrations for demineralization process are not similar [ 23 ]. Their optimized concentration of HCl for demineralization process of the marine waste samples is different from each other' or even from our results, even though, they used the same method for the demineralization process of marine samples and the same process was used for the quantification of minerals in the demineralized crab shell samples by using ICP-OES analysis [ 14 ].…”

Chitin is an organic polymer and it is the most frequent marine natural polysaccharide after cellulose. The main natural sources of chitin are exoskeletons of insects, mollusks, the cell walls of certain fungi and crustaceans such as crabs, shrimps and lobsters. The waste of these marine exoskeletons are pollutant for the environment, but these waste raw materials could be useful for production of commercial products like chitin. Chitin is an important raw material used for water treatment, agricultural, biomedical, biotechnological purposes, food and paper industry and cosmetics. Based on the variety of importance, the present targets of this study are to optimize the demineralization process for the removal of calcium and phosphate contents from the waste of Portunidae segnis ( P. segnis ) by using acid at ambient temperature and to characterize the isolated demineralized sample as well as the percentage of remaining calcium and phosphorus contents by using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). The prepared waste carbs coarse powder samples of P. segnis were demineralized with seven different concentrations of hydrochloric acid at ambient temperature for 1 h. All the demineralization samples by the different concentrations were analyzed by using sensitive ICP-OES. The results based on ICP-OES showed that among the seven different concentrations used in the demineralization process for the isolation of chitin, the best was 2 M of HCl concentration for the production of chitin. The results also showed that the optimized concentration 2 M HCl gave the minimum concentration of calcium and phosphorus compared to other concentrations applied in this experiment. In conclusion, the optimized concentration for demineralization process could be used commercially for the isolation or commercial production of chitin for agricultural, biomedical and biotechnological purposes.

“…For commercial purposes, chitin is extracted using chemical, electrochemical and biochemical methods from the cuticles of crustaceans, mostly crabs and shripms [19][20][21][22][23][24] and corals [25]. It is isolated by chemical extraction via three stages, i.e., deproteinization by alkaline treatment, i.e., employing NaOH, Na 2 CO 3 , NaHCO 3 , KOH, K 2 CO 3 , demineralization using acidic (i.e., HCl, HNO 3 , H 2 SO 4 , CH 3 COOH), or EDTA-based solutions [26], and finally discoloration following the incubation in alkaline solution or by the addition of acetone or, alternatively, using KMnO 4 , H 2 O 2 [27] or oxalic acid [12,28].…”

The growing demand for new, sophisticated, multifunctional materials has brought natural structural composites into focus, since they underwent a substantial optimization during long evolutionary selection pressure and adaptation processes. Marine biological materials are the most important sources of both inspiration for biomimetics and of raw materials for practical applications in technology and biomedicine. The use of marine natural products as multifunctional biomaterials is currently undergoing a renaissance in the modern materials science. The diversity of marine biomaterials, their forms and fields of application are highlighted in this review. We will discuss the challenges, solutions, and future directions of modern marine biomaterialogy using a thorough analysis of scientific sources over the past ten years.
