Abstract

The egg mass of the wedge seahare Dolabella auricularia has been gathered as human food for quite a long time without knowing its nutritional composition. Thus, this study was conducted in order to determine some nutritional aspects of the egg mass as basis of its utilization as human food. Important composition of the egg mass that were determined were its proximate composition, mineral contents and amino acid profile. In terms of proximate composition, the egg mass has a moisture content of 91.10 percent, fat of 0.85 percent, protein of 2.85 percent, ash of 3.43 percent and 1.77 percent for carbohydrates. The mineral content such as: calcium, iron, potassium, sodium and zinc contain 1040 mg/kg, 25.3 mg/kg, 599 mg/kg, 9803 mg/kg and 41.6 mg/kg, respectively. The amino acid profile has six (6) essential amino acids such as: threonine, valine, isoleucine, leucine, phenylalanine and hstidine while it has nine (9) non-essential amino acid like: taurine, aspartic acid, serine, glutamic acid, glumatimine, glycine, alanine, tyrosine, proline. It has also eight (8) other amino acids components such as: Phospo-serine, urea, aromatic amino acid, citrulline, beta-alanine, gamma-aminobutyric acid, ammonia, ornithine. Results show that the egg mass of the wedge seahare contains some nutritional components that are very essential in maintaining a healthy and balanced life, thus making it as another food commodity from the marine environment.
