Abstract

Ulva lactuca is a potential source of functional salt. The production of the functional salt is limited by the fishy smell of the product. The purpose of this research was to determine the concentration of activated charcoal that can reduce the fishy odor of seaweed salt. The functional salt was extracted using activated charcoal at 0.5; 0.75; 1; 1.25 and 1.5%. The sensory and functional properties of the salt including mineral content, Na: K ratio, NaCl levels, total phenol and antioxidant activity were characterized. The sensory tests showed that 1.5% activated charcoal improved salt's consumer acceptance. The selected functional salt contained Na 91.00±1.28 g/kg; K 44.88±0.06 g/kg with a Na: K ratio of 2.03±0.03. This salt also contained NaCl 9.08±0.42%; total phenols of 13.72±0.19 mg GAE/g extract and antioxidant activity expressed by IC50 1681.27±3.80 mg / L.

Abstract

Tujuan penelitian ini yaitu menentukan proporsi terbaik bubur rumput laut dalam menghambat kemunduran mutu ikan nila. Proporsi bubur rumput laut yang digunakan yaitu 0; 12,5; 25; 50%. Parameter uji meliputi organoleptik, derajat keasaman, total mikroba, dan total volatile base (TVB). Penelitian ini meliputi preparasi sampel, analisis fitokimia, pembuatan proporsi bubur rumput laut, serta penentuan proporsi bubur rumput laut terbaik. Penelitian dilakukan pada suhu ruang dengan dua kali ulangan. Hasil analisis fitokimia ekstrak metanol menunjukkan bahwa S. polycystum mengandung senyawa alkaloid, steroid, flavonoid, fenol, dan tanin. Proporsi bubur rumput laut 25% merupakan perlakuan terbaik dalam mempertahankan mutu ikan nila hingga waktu penyimpanan jam ke-6. Semakin lama waktu penyimpanan maka ikan nila semakin mengalami kemunduran mutu.
