Abstract

Seaweed is one of the most extensively used as functional foods and medicinal herbs with a long history in Asian countries. Seaweed is one of food materials with high content of iodine and dietary fiber. There are three classes of seaweed, named Chlorophyceae (green algae), Rhodophyceae (red algae), and Phaeophyceae (brown algae). Eucheuma cottonii and Eucheuma spinosum are Rhodophyceae (red algae) that can be found in Indonesian waters. The purpose of this study is on development of ready-to-drink edible bird’s nest using Eucheuma cottonii to enhance the nutritional value and bioavailability. The objective of this study is to enhance nutritional value of ready-to-drink edible bird nest (RTD-EBN) by Eucheuma Cottonii and incorporate bioactive flavonoids and other possible natural antioxidants from Eucheuma Cottonii, including phlorotannins and fucoidan in RTD-EBN. In this study, different ratio of Eucheuma Cottonii and edible bird’s nest were studied. Proximate analysis, total sugar content and antioxidant properties and sensory evaluation were carried out to evaluate the organoleptics and sensory characteristics of ready-to-drink edible bird nest (RTD-EBN) with Eucheuma Cottonii. Microbiological testing were also carried out to ensure safety of food product. The antioxidant properties for the best formulations among three samples were: DPPH Radical Scavenging Activity (36.72 ± 0.18%), Total Phenolic Content (56.42 ± 0.29 mg GAE/g) and Total Flavonoids Content (189.98±1.26 mg CAE/g). The proximate analysis of the best formulation were: total sugar (1.72 ± 0.03 %), crude protein (1.07 ± 0.18 %), crude fiber (7.75 ± 0.32%), ash (3.67 ±1.15 %), Calcium (300.00± 7.81 mg), potassium (54.54 ± 0.53 mg) and magnesium (26.52 ± 0.42 mg). Sensory were evaluated with many attributes, each attribute is significant differences (p<0.05) among the ready-to-drink edible bird nest (RTD-EBN) with Eucheuma Cottonii and the reference.
