Abstract

The nutritional composition of the dried seaweed Ulva lactuca from Pameungpeuk waters, including proximate, vitamins, minerals, dietary fibre and heavy metal has been carried out. The objective of this present study is to know the nutritional composition of the dried seaweed U. lactuca for utilisation in human nutrition in the future. Results show that carbohydrate was the major component in the proximate analysis of U. lactuca in the present study. The carbohydrate content was 58.1%. Moisture, ash, protein and fat content were 16.9%, 11.2%, 13.6% and 0.19% respectively, while dietary fibre was 28.4%. The vitamin A content was examined in this study less than 0.5 IU/100 mg while vitamin B1 (thiamine) and vitamin B2 (riboflavin) were 4.87 mg/kg and 0.86 mg/kg respectively. The calcium content was 1828 mg/100 g higher than other minerals. The heavy metal content examined in this study were lower than the limit of the quality criteria applied to edible seaweeds sold in Indonesia. Based on the results of this study show that U. lactuca has potential to be developed as an alternative source of a healthy food for human in the future.

Highlights

Many current and potential uses of seaweeds have been identified and these have been separated into 10 categories: (1) agriculture, horticulture and agronomy, (2) uses in animal aquaculture, (3) aesthetics, (4) cosmetics, (5) environmental health, monitoring and remediation, (6) food, (7) health, thalassic and wellness, (8) industry, (9) pharmaceutical and pharmacology and (10) science, technology and biomedicine (Apaydin et al 2010).Seaweeds have been used as food, animal feeds, fertiliser and as sources of traditional medicine in many Asian civilisations since ancient times

Summary

Introduction

Seaweeds have been used as food, animal feeds, fertiliser and as sources of traditional medicine in many Asian civilisations since ancient times. In order to fully exploit the nutritional composition of various seaweeds. The biochemical composition of marine seaweeds is generally known to be highly influenced by geographical location and local environmental condition (Rohani-Ghadikolalel et al 2012). Seaweed possess nutrient potentials, and nutraceutical potentials like antioxidant, antimutagenic, anticoagulant, anticancerous and antibacterial activity (Abirami & Kowsalya 2011). Seaweeds can be considered as promising plants forming one of the important marine living resources of high nutritional value. Being plants of unique morphology and biochemical composition, U. lactuca could be exploited for their multifunctional properties in the form food, energy, medicine and as biotechnological tools (Abirami & Kowsalya 2011)
