What is Lactalbumin Phosphate?
Lactalbumin Phosphate (CAS Number: 977051-00-5) is a chemically modified form of lactalbumin, a naturally occurring whey protein derived from milk. The compound is created through phosphorylation—a process that adds phosphate groups to the protein structure. This modification may alter the protein's functional properties, including its solubility, emulsifying capacity, or binding characteristics. Lactalbumin itself comprises approximately 20% of whey protein and is valued in the dairy and nutrition industries for its amino acid profile and bioavailability.
Common Uses
The specific applications of Lactalbumin Phosphate in food products are not clearly documented in mainstream food science literature. Unlike many other phosphorylated proteins used in food manufacturing, there is limited public information regarding its commercial use or prevalence in food formulations. It may potentially be investigated for use in nutritional supplements, functional foods, or specialized dairy applications, but concrete commercial applications remain unclear. The phosphorylation process is sometimes used in food science to improve protein functionality in specific industrial contexts.
Safety Assessment
No adverse events related to Lactalbumin Phosphate have been reported to the FDA, and there are no documented FDA recalls associated with this additive. Since it is derived from milk—a common food ingredient—the base compound (lactalbumin) has a long history of safe use in human nutrition. However, the safety profile of the phosphorylated form specifically has not been extensively characterized in published scientific literature.
Individuals with milk allergies or lactose intolerance should note that this additive is dairy-derived, though the degree of allergenic potential may differ from whole milk proteins depending on processing methods. The phosphorylation process may affect protein structure in ways that could theoretically alter allergenic properties, but this has not been systematically studied for this particular compound.
Regulatory Status
Lactalbumin Phosphate is not currently listed as Generally Recognized As Safe (GRAS) by the U.S. FDA, which means it has not undergone the formal GRAS determination process. This does not necessarily indicate safety concerns; rather, it reflects that the compound has not been the subject of a formal safety evaluation petition or that such an evaluation has not been completed. The compound is not explicitly banned by the FDA. Regulatory status in other jurisdictions, including the European Union, is not clearly documented in available sources.
For a food additive to be legally used in the United States without GRAS status, it would typically require FDA food additive approval through the petition process, which involves submitting safety data and manufacturing information to the agency.
Key Studies
Published scientific literature specifically examining Lactalbumin Phosphate is extremely limited. Most research on phosphorylated proteins focuses on their functional properties in food systems—such as improved water-binding capacity or emulsification—rather than on safety assessment. General research on whey proteins and lactalbumin demonstrates their safety and nutritional value in human consumption.
The lack of published studies on this specific compound highlights a significant gap in available safety data. To establish a more comprehensive safety profile, toxicological studies, allergenicity assessments, and functional food applications would need to be formally evaluated and published.
Consumers seeking more information about Lactalbumin Phosphate in specific products should consult product labeling or contact manufacturers directly, as transparency regarding this ingredient's use and purpose remains limited.
