Feed Grade Monosodium Phosphate CAS 7558-80-7

Product Description

Among all phosphates, several parameters can differ, such as the P digestibility, the pH, or the calcium level.Indeed, Calcium (Ca) is an important parameter to consider. it is important for the skeleton formation and maintenance, but in excess in diet, Ca can reduce the P bioavailability by complexation (Hossain & Yoshimatsu, 2014). Moreover, Calcium (Ca) can be absorbed directly from water via gills and intestine (Kaushik, 2005). So, to bring a phosphate source without calcium can help to balance the feed formula.A Monosodium phosphate (MSP) doesn't contain calciumA A compared to conventional phosphates used in aquafeed like monocalcium phosphate (MCP). The ingredient pH should be take into account in the aquafeed formulation because dietary acidifications can increase P digestibility in trout (>+16%) (Sugiura etA al., 2006) and shrimp (Piedad-Pascual, 1989; Lemos etA A al., 2021).A A Monosodium phosphate (MSP) has an acidic pHA A such as monoammonium phosphate (MAP) and thus contributes to the global acidification of the diet. Lastly, it is essential to consider the water solubility and digestibility of phosphorus. Indeed, better are the P water solubility, better will be the P digestibility for fish.A A Monosodium phosphate (MSP) has a high P water solubility (95%)A A among the inorganic feed phosphates, which consequently leads toA A a high phosphorus digestibility in aquafeed. As an example, in trout, Morales et al., 2018 have proved thatA A MSP has a high P digestibility (91.1%), close to MAP (92.9%).
