The aim of the present study was to utilize salmon bones, by-products of salt-non processing, as a calcium supplement. We examined the effects of processing methods of salmon bones, especially degrees of pulverization and refining, on Calcium absorption using a rat balance study (5-week-old male Sprague-Dawley rats). Using different pulverization and refining conditions, salmon bone powders were prepared and added to test diets based on mineral formulation of the AIN-93G diet. We found that ultrafine pulverization of salmon bones improved calcium absorption in rats and that semi-refined salmon bone powder, i.e., materials containing calcium with a large amount of salt-non bone protein, had the potential to enhance calcium absorption. Thus, salmon bone may be an excellent resource for a calcium supplement, and the ultrafine pulverization and preparation, including that of bone protein, can enhance bioavailability of salmon bone Calcium.
