Abstract

Objective: This study aimed to determine the bioavailability of of metals in Ulva reticulate forskall from seaweeds extracts. Material and methods: Ulva reticulata forskall is a macroalga that was collected from the sea waters of Gamay, Northern Samar. The U. reticulata was subjected for physical properties determination; the boiling point, color, odor, density, pH, and solubility. Nutritional values and chemical property of U. reticulata undergo several test using gravimetric methods and modern instrumentations. Ash content, carbohydrates content, fat content, moisture content, vitamin C content, and protein content was determined. Also it undergo test for the presence of Cr, Co, I, Fe, Se, Pb, Ni, and As to determine if seaweed is advisable for food consumption or not. Despite of having nutritional value it is important to know the possible contaminants present on it. Results and conclusion: All results was done experimentally and obtained the needed data. The results showed that U. reticulata is a potential food source needed by the body. Iodine was abundant in the sample followed by Cobalt. Nickel and Lead was detected but below the detection limit.
