    • Abstract:
      Research background. In India, widespread dietary deficiency in calcium and vitamin D is a significant public health concern. Over the past five decades, evidence has shown a decline in dietary calcium intake in rural, tribal and urban populations. This persistent deficiency poses a serious risk to bone health and contributes to the development of rickets, osteoporosis and osteopenia, as well as potential disturbances in metabolic rates and physiological functions. A key factor in this decline appears to be the reduced consumption of calcium-rich dairy products. As a result, research is exploring alternative, highly bioavailable sources of calcium, such as those derived from fish bone waste. The potential of nano-calcium supplements to improve absorption and bone density compared to traditional supplements is an area of active investigation. Experimental approach. Nano-calcium powder was synthesised from the bones of two commercial fish species, Daysciaena albida and Otolithes ruber, ethically sourced from the Kerala coast following relevant regulations. Alkali extraction method was used and the resulting nano-calcium powder was characterized by various physiological and chemical analyses. Results and conclusions. The yield percentage of two samples was different. Notably, both samples had different colour properties, proximate composition and results of scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). The nano-calcium from D. albida also contains slightly more calcium and phosphorus than that from O. ruber. The nanoparticles of the calcium from D. albida (d=153.8 nm) were also smaller than the nanoparticles of the calcium from O. ruber (d=337.1 nm). Interestingly, further analyses using techniques such as Fourier transform infrared spectroscopy (FTIR), zeta potential, thermogravimetric analysis (TGA) and X-ray diffraction (XRD) showed significant similarity between the nano-calcium samples from D. albida and O. ruber, despite the in
      Pozadina istraživanja. U Indiji bitnu prijetnju javnom zdravlju predstavlja nutritivni manjak kalcija i vitamina D. Istraživanja pokazuju da u posljednjih pet desetljeća dolazi do smanjenja unosa kalcija putem prehrane u ruralnim, plemenskim i urbanim populacijama. Ovaj trajan nedostatak predstavlja ozbiljan rizik za zdravlje kostiju i pridonosi razvoju rahitisa, osteoporoze i osteopenije, kao i mogućim poremećajima metabolizma i fizioloških funkcija. Ključni faktor nastanka ovih poremećaja je najvjerojatnije manji unos mliječnih proizvoda bogatih kalcijem. Stoga se istraživanja usmjeravaju na alternativne izvore kalcija velike bioraspoloživosti, poput onog dobivenog iz otpada kostiju riba. Aktivno se istražuje mogućnost primjene dodataka prehrani koji sadržavaju nanočestice kalcija, u svrhu poboljšanja apsorpcije kalcija i gustoće kostiju, u usporedbi s tradicionalnim dodacima. Eksperimentalni pristup. Prah nanočestica kalcija sintetiziran je iz kostiju dviju komercijalnih vrsta riba, Daysciaena albida i Otolithes ruber, ulovljenih u obalnom području Kerale u skladu s lovačkom etikom i relevantnim propisima. Za ekstrakciju kalcija je korištena natrijeva lužina, a dobiveni prah nanočestica kalcija okarakteriziran je ispitivanjem različitih fizioloških i kemijskih svojstava. Rezultati i zaključci. Postotak prinosa dvaju uzoraka bio je različit. Zamijećeno je da su uzorci imali različita svojstva boje i različit sastav, pa su se i rezultati pretražne elektronske mikroskopije s energijski razlučujućom rendgenskom spektroskopijom (SEM-EDX) razlikovali. Nanočestice kalcija dobivene iz vrste D. albida sadržavale su nešto više kalcija i fosfora od onih iz vrste O. ruber. Nanočestice kalcija iz vrste D. albida bile su i manje (d=153,8 nm) od nanočestica kalcija iz vrste O. ruber (d=337,1 nm). Zanimljivo je da se daljnjim ispitivanjima pomoću tehnika poput Fourierove transformacijske infracrvene spektroskopije (FTIR), određivanja zeta potencijala, termogravimetrijske analize
