Introduction: Seaweed is considered as a promising alternative food source for animals, with numerous benefits, such as high growth rates, exceptional tolerance for potential seawater breeding, and no occupation of arable land. The aim of this study was to evaluate the nutritional value (approximate composition, amino acid and fatty acid), phytochemical (sterol, phenol and flavonoid) and antioxidant activity (diphenylpicryl hydrazyl (DPPH) of aqueous extract of brown algae macroalgae Sargassum ilicifolium, Nizimuddinia zanardini, Cystoseira indica and Padina australis was performed.
Material & Methods: In this study, after collecting macroalgae from the tidal areas of Chabahar coasts, they were washed and after drying in a ratio of 1: 1: 1, they were combined and turned into a powder. Chemical composition was measured by AOAC method, fatty acids by chromatography, amino acids by HPLC, sterol by gas and phenol chromatography, flavonoids and antioxidant activity by spectrophotometer.
Results: The results showed that the amount of protein, fat, carbohydrate, ash and moisture were 6.38, 1.30, 0.86, 5.10, 2.20 and 85.46 g per 100 g of fresh weight of premix and the amount of crude energy, respectively. 4238.86 calories per gram was premix. The predominant saturated fatty acids in the premix of macroalgae tested were palmitic acid (15.11±0.89%), myristic acid (10.51±0.28%) and stearic acid (8.54±0.43%), respectively. Among monounsaturated fatty acids, oleic acid (7.49±0.97%) and among long chain unsaturated fatty acids (PUFA), respectively, arachidonic acid (20.48±4.23%), linoleic Acid (18.32±6.12%) and alpha linolenic acid (6.50±78 0.78%) were predominant. The total essential and non-essential amino acids were 7.88 and 11.41 amino acids per 100 g, respectively. Glutamic acid (4.12±0.02 amino acid per 100 g of sample), aspartic acid (1.71±0.05 g of amino acid per 100 g of sample) and serine (1.64±0.09 g of amino acid per 100 g of sample) was dominated by non-essential amino acids, respectively. The predominant sterol was cytostanol. The total sterol content was 234.54±12.18 mg/100 g dry matter. Cholesterol and cholesterol levels were 6.36±0.62 and 5.38±0.21 mg/100g dry matter, respectively. Phenol, flavonoids and antioxidant activity of premix aqueous extract were 83.46±7.7mg GAE/g extract, 10.01±0.98 mg QE/g dry extract and 1323.87±11.28 μmol TE/g, respectively.
Conclusion: It was an extract. Overall, the results of this study showed that due to the presence of long-chain unsaturated fatty acids, the balance between essential and essential amino acids, sterols and natural antioxidants, the use of macroalgae premix. S. ilicifolium, N. zanardini, C. indica and P. australis are recommended in food and pharmaceutical industries. |
