Nutritional value of sea cucumber Acaudina molpadiodes from Delta Wulan Estuary, Demak Regency, Central of Java, Indonesia

Abstract

Sea cucumber Acaudina molpadiodes has a nutritional value that can be utilized as a functional food for humans. Therefore, this study aims to examine the composition of proximate, fatty acid, and amino acids in A. molpadiodes. The samples were collected from Delta Wulan Estuary, Demak Regency, Central Java, Indonesia. Based on the result of this study, the average value of moisture, protein, carbohydrate, total lipid, and ash contents in A. molpadiodes ranged between 90.44 – 91.23%, 4.44 – 4.97%, 4.12-4.35%, 0.16-0.18%, and 0.05-0.06% respectively. According to the result of amino acid analysis, the profile of essential amino acids comprised phenylalanine, isoleucine, valine, lysine, leucine, threonine, histidine, cysteine, methionine, and tryptophan. The average value of leucine content was 2273.95 ± 291.61 mg.kg-1, and the threonine content was 2732 ± 276.93 mg.kg-1. The non-essential amino acid profile consisted of glutamic acid, alanine, glycine, aspartic acid, tyrosine, proline, and taurine. The glycine and glutamic acid content in A. molpadiodes are 6843.67 ±393.71 mg.kg-1 and 5975.06 ± 687.85 mg.kg-1. Fatty acid profiles in A. molpadiodes are DHA (docosahexaenoic), EPA (Eicosapentaenoic acid), and AA (Arachidonic acid with an average value of 2.03 ±0.17 mg.100g-1, 2.42 ± 0.83 mg.100g-1, and 6.20±1.56 mg.100g-1.
