ABSTRACT
The two selected macro algae, namely, Gracilaria verrucosa (Red algae) and Enteromorpha compressa (Green algae) were seasonally collected from the central sector of Chilika lagoon and analyzed for their biochemical and mineral contents during 2022-23. The composition of biochemical components such as lipid, protein, carbohydrate, ash, nitrogen, total fiber and mineral contents like calcium, magnesium, phosphorus, potassium, sodium, iron, zinc, iodine, nickel, copper, molybdenum and selenium ware studied. The values of each triplicate sample were expressed on dry weight basis as the mean value with SD. The different proximate components of two species ranged from 27.4 to 56.2% (carbohydrate), 7.8 to 12.5 % (lipid), 28.8 to 57.1% (protein), 4.5 to 7.4% (ash), 11.65 to 14.95% (nitrogen) and 36 to 92% (total fiber) dry weight, respectively. E. compressa had higher mineral content than G. verrucosa such as calcium, magnesium, phosphorus during monsoon and post monsoon season, respectively. Seasonal variation affected mineral contents with some fluctuations of biochemical composition across species G. verrucosa and E. compressa showing rich in protein, carbohydrate and low level of ash percentage during post-monsoon. The results showed that the carbohydrate and protein were in inverse relationship, while protein, nitrogen, ash and fiber levels were correlated positively. Among the minerals, calcium, potassium, sodium, iron, zinc, iodine having significantly higher value were observed in E. compressa during all seasons than that of G. verrucosa. Hence, marine macro algae have been gaining importance due to nutritive value and suggesting that the seaweed species have potential to be used as raw material of a healthy food for human being.
