Abstract

Egg masses of the wedge sea hare Dolabella auricularia are gathered as human food in the Visayas region and other areas in the Philippines, but there have been no studies examining their appropriateness for human consumption. This study was conducted to characterize the biochemical components of the egg masses. Biochemical characterization was assessed through proximate composition analysis and an amino acid profile. The egg masses comprised 91.10 percent moisture, 3.43 percent ash, 2.85 percent crude protein, 1.77 percent carbohydrates, and 0.85 percent fats. The 23 amino acid included six (6) essential components, nine (9) non-essential components, and eight (8) others. The essential amino acids included leucine, valine, isoleucine, phenylalanine, threonine and histidine, while the non-essential amino acids included taurine, tyrosine, serine, glycine, aspartic acid, glutamic acid, alanine, glutamine and proline. The other components included phospho-serine, urea, aromatic amino acid, citrulline, beta-alanine, gamma-aminobutyric acid, ammonia and ornithine. The results show that egg masses contain amino acids that are important for human health, thus making it another food commodity from the ocean.
