Nopparut Sitthiwong

Abstract


Edible freshwater macroalgae are normally found in natural water sources and local markets, and are commonly consumed as a traditional type of food in north-eastern Thailand. Macroalgae has been found to possess high nutritional value and contain various bioactive compounds. The focus of this research study was to examine the diversity of edible macroalgae, chlorophyll and to assess the nutritional value of the macroalgae samples collected from 12 water resources of Sakon Nakhon, Nakhon Phanom and Mukdahan Provinces. Only one genus of Spirogyra spp. was found in the collection process. The macroalgae samples collected from each sampling site were dried and the pigment quantity and nutritional value were analyzed. The highest quantity of chlorophyll a, b and the carotenoid content were recorded at 4.067, 1.716 and 1.209 mg/g of cell dry weight, respectively. The samples were tested for their basic nutritional value and the highest values of ash, fat, moisture, protein, carbohydrate and energy were recorded at 17.37, 5.51, 14.90, 22.77, 67.13 g/100g and 363 kcal/100g, respectively.
