Evaluating antioxidant property of brown ALGA Colpomenia sinuosa (DERB. ET SOL)

  The brown alga, Colpomenia sinuosa was subjected to DPPH (1,1-diphenyl-2-picryl hydrazyl), nitric oxide radical, hydrogen peroxide, scavenging of ABTS radical and Total antioxidant capacity (TAC) inhibitory assays to assess its antioxidant property. The dimethyl sulphoxide (DMSO) and methanol extracts showed highest antioxidant activity in DPPH (96.56 and 88.57%), nitric oxide radical (81.2 ±...

Characterization of the gelatin of the flying gurnard (Dactylopterus volitans) and its interaction with starch

  Gelatin extracted from the skin of the flying gurnard (Dactylopterus volitans L,)was characterised and its interaction with cassava starch mixtures of different ratio concentrations was investigated by rheology and differential scanning calorimetry (DSC). Protein and moisture were the main proximate composition, whilst glycine was the main amino acid. The gelatin had high bloom (275 g) strength with...
